Question

当我在textview或imageview中使用VectorDrawable资源时，使用“android：DrawableRight”/“android：DrawableEnd”/“android：DrawableStart”/“android：DrawableLeft”时会出现运行时崩溃。

该应用程序将编译正常，没有任何警告。

我正在使用

Gradle 1.5
支持库23.2（'com.android.support:appcompat-v7:23.2.0'）

我发现我可以通过编程方式在Java中分配SVG，而不会像这样崩溃。

TextView tv = (TextView) findViewById(R.id.textView);
tv.setCompoundDrawablesWithIntrinsicBounds(null,null, getResources().getDrawable(R.drawable.ic_accessible_white_36px),null);

（我怀疑这是23.2的支持库错误。）

但是可以将drawableRight等用于SVG资产吗？

这是我的布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="au.com.angryitguy.testsvg.MainActivity">


<TextView
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:drawableRight="@drawable/ic_accessible_white_36px"
    android:background="@color/colorPrimary"
    android:textColor="#FFFFFF"
    android:textSize="22sp"
    android:text="Hello World!"/>
</RelativeLayout>

这是我的活动

package au.com.angryitguy.testsvg;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        }
    }

以下是Google材料设计网站中未经修改的VectorDrawable资产。

<vector android:height="24dp" android:viewportHeight="24.0"
    android:viewportWidth="24.0" android:width="24dp" xmlns:android="http://schemas.android.com/apk/res/android">

</vector>

这是我的app build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "au.com.angryitguy.testsvg"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        // Stops the Gradle plugin’s automatic rasterization of vectors
        generatedDensities = []
    }
    // Flag to tell aapt to keep the attribute ids around
    aaptOptions {
        additionalParameters "--no-version-vectors"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.0'
}

这是崩溃。（注意引用textview的膨胀错误。）

Answer 1

可以将drawableRight等用于SVG资产吗？

是

AppCompatTextView now支持app:drawableLeftCompat，app:drawableTopCompat，app:drawableRightCompat，app:drawableBottomCompat，app:drawableStartCompat和{{1}复合drawables，支持向后移植的可绘制类型，例如app:drawableEndCompat。

将其包含在您的gradle文件中

VectorDrawableCompat

在文字视图中，您可以使用

implementation 'androidx.appcompat:appcompat:1.1.0-alpha01'

旧答案

由于Google似乎不会在短期内对此问题采取任何措施，因此我不得不为我的所有应用提出更可靠的可重用解决方案：

首先在应用“res / values / attrs.xml”的attrs.xml文件中添加自定义 TextView 属性：
```
app:drawableLeftCompat
app:drawableStartCompat
```

然后像这样创建自定义TextView类：

<resources>
    <declare-styleable name="CustomTextView">
        <attr name="drawableStartCompat" format="reference"/>
        <attr name="drawableEndCompat" format="reference"/>
        <attr name="drawableTopCompat" format="reference"/>
        <attr name="drawableBottomCompat" format="reference"/>
    </declare-styleable>
</resources>

现在，您可以通过自定义属性在任何布局中轻松使用它：

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.drawable.Drawable;
import android.os.Build;
import android.support.v7.content.res.AppCompatResources;
import android.support.v7.widget.AppCompatTextView;
import android.util.AttributeSet;

public class CustomTextView extends AppCompatTextView {
    public CustomTextView(Context context) {
        super(context);
    }    
    public CustomTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initAttrs(context, attrs);
    }
    public CustomTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initAttrs(context, attrs);
    }

    void initAttrs(Context context, AttributeSet attrs) {
        if (attrs != null) {
            TypedArray attributeArray = context.obtainStyledAttributes(
                    attrs,
                    R.styleable.CustomTextView);

            Drawable drawableStart = null;
            Drawable drawableEnd = null;
            Drawable drawableBottom = null;
            Drawable drawableTop = null;
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                drawableStart = attributeArray.getDrawable(R.styleable.CustomTextView_drawableStartCompat);
                drawableEnd = attributeArray.getDrawable(R.styleable.CustomTextView_drawableEndCompat);
                drawableBottom = attributeArray.getDrawable(R.styleable.CustomTextView_drawableBottomCompat);
                drawableTop = attributeArray.getDrawable(R.styleable.CustomTextView_drawableTopCompat);
            } else {
                final int drawableStartId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableStartCompat, -1);
                final int drawableEndId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableEndCompat, -1);
                final int drawableBottomId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableBottomCompat, -1);
                final int drawableTopId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableTopCompat, -1);

                if (drawableStartId != -1)
                    drawableStart = AppCompatResources.getDrawable(context, drawableStartId);
                if (drawableEndId != -1)
                    drawableEnd = AppCompatResources.getDrawable(context, drawableEndId);
                if (drawableBottomId != -1)
                    drawableBottom = AppCompatResources.getDrawable(context, drawableBottomId);
                if (drawableTopId != -1)
                    drawableTop = AppCompatResources.getDrawable(context, drawableTopId);
            }

            // to support rtl
            setCompoundDrawablesRelativeWithIntrinsicBounds(drawableStart, drawableTop, drawableEnd, drawableBottom);
            attributeArray.recycle();
        }
    }
}

您可以使用按钮， EditText 和 RadioButton 执行类似操作，因为它们来自TextView

希望这会有所帮助：）

Answer 2

此解决方案不再正确。从23.3.0版本开始，矢量drawable只能通过app：srcCompat或setImageResource（）

加载

尝试将矢量drawable包装到layer-list或selector中：

<TextView
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:drawableRight="@drawable/ic_accessible_white_wrapped"
    android:background="@color/colorPrimary"
    android:textColor="#FFFFFF"
    android:textSize="22sp"
    android:text="Hello World!"/>

ic_accessible_white_wrapped.xml：

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_accessible_white_36px"/>
</layer-list>

Answer 3

我找到的最佳方式：

Drawable leftDrawable = AppCompatResources.getDrawable(this, R.drawable.ic_search);
search.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, null, null);

Answer 4

补充一些答案：您可以将VectorDrawable作为drawableLeft（等）使用，但这取决于支持库版本，并且需要付出代价。 < / p>

在哪些情况下有效？我已经this diagram提供帮助（对支持库23.4.0有效 - 至少 - 25.1.0）。

Answer 5

其他答案都不起作用，这里是我如何向VectorDrawable添加TextView，在处理{{1}时应使用VectorDrawableCompat.create()在VectorDrawables下面：

Android L

简短，甜蜜，至关重要！

Answer 6

来自Google：从Android支持库23.3.0开始，支持向量 drawable只能通过app：srcCompat或setImageResource（）..
加载

http://android-developers.blogspot.ru/2016/02/android-support-library-232.html

Answer 7

可以在xml中直接设置矢量drawable，但是你已经包含了数据绑定框架。

只需写下

<TextView
...
android:drawableRight="@{@drawable/ic_accessible_white_36px}"/>

并将整个布局包装在<layout>标记中，所以基本上你的xml看起来像：

<?xml version="1.0" encoding="utf-8"?>
<layout>

    <RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"

要激活数据绑定框架，只需添加

android {
    ....
    defaultConfig {
        dataBinding {
            enabled = true
        }
    }
}

您不必使用绑定库的任何其他功能

修改

当然如果你想使用pre-Lollipop的矢量drawables，你必须使用
启用支持向量drawables
vectorDrawables.useSupportLibrary = true

所以你的build.gradle需要2个新命令：

android { .... defaultConfig { vectorDrawables.useSupportLibrary = true dataBinding { enabled = true } } }

我通过所有答案并使用最新的Android studio 3.0.1和appcompat支持库26.1.0，我可以保证这个工作正常。

在build.gradle（app）文件中

android {
    compileSdkVersion 26
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
    }
}

dependencies {
    implementation 'com.android.support:appcompat-v7:26.1.0'
}

在Activity中，扩展AppcompatActivity包含了这个方法，即静态块

static {
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}

或者如果您希望将其应用于整个应用程序，请在此处包含此行扩展应用程序类的类

override fun onCreate() {
    super.onCreate()
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true)
}

xml中的Textview

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="vertical">

<TextView
        android:id="@+id/passName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:drawableLeft="@drawable/account_drawableleft_selector"
        android:drawablePadding="5dp"
        android:ellipsize="marquee"
        android:fontFamily="@font/montserrat_light_family"
        android:gravity="center_vertical"
        android:marqueeRepeatLimit="marquee_forever"
        android:paddingRight="10dp"
        android:scrollHorizontally="true"
        android:singleLine="true"
        android:textColor="@color/app_text_color"
        android:textSize="12sp"
        tools:text="Account Name" />
</LinearLayout>

account_drawableleft_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_account_circle_24dp" /> <!-- checked -->
</selector>

Answer 9

自appcompat:1.1.0起，您可以使用

app:drawableLeftCompat
app:drawableStartCompat
...

Answer 10

如果您正在使用绑定，还有另一种神奇的方法可以使用相同的方法在TextView中使用向量。将它们包装成：

android:drawableLeft="@{@drawable/vector_ic_access_time_24px}"
android:drawableStart="@{@drawable/vector_ic_access_time_24px}"

这将神奇地起作用，我没有调查幕后发生的事情，但我猜TextView正在使用getDrawable或类似的AppCompatResources方法。

Answer 11

我为此设计了一个小型图书馆 - textview-rich-drawable（它还支持定义复合绘图＆＃39;尺寸和着色）。

<com.tolstykh.textviewrichdrawable.TextViewRichDrawable
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Some text"
    app:compoundDrawableHeight="24dp"
    app:compoundDrawableWidth="24dp"
    app:drawableTopVector="@drawable/some_vector_drawble"
    app:drawableEndVector="@drawable/another_vector_drawable"
    app:drawableTint="@color/colorAccent" />

依赖

compile 'com.tolstykh.textviewrichdrawable:textview-rich-drawable:0.3.2'

Answer 12

在build.gradle（app）文件中

android {
    compileSdkVersion 26
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
    }

    dataBinding {
        enabled = true
    }
}



public class BindingUtils {
    @BindingAdapter("android:drawableRight")
    public static void setDrawableStart(TextView textView, int resourceId) {
        Drawable drawable = AppCompatResources.getDrawable(textView.getContext(), resourceId);
        Drawable[] drawables = textView.getCompoundDrawables();
        textView.setCompoundDrawablesWithIntrinsicBounds(drawable,
                drawables[1], drawables[2], drawables[3]);
    } 
}

使用（当数据绑定时）

android:drawableRight="@{viewModel.ResId}"

或（正常）

android:drawableRight="@{@drawable/ic_login_24dp}"

Answer 13

基于Behzad Bahmanyar的answer，我注意到我无法对正常的png文件使用android的正常属性：

android:drawableTop
android:drawableBottom
etc

因为它将被替换为null

Drawable drawableTop = null;
...
setCompoundDrawablesRelativeWithIntrinsicBounds(drawableStart, drawableTop, drawableEnd, drawableBottom);

如果未设置app:drawableTopCompat，但是设置了android:drawableTop（例如）。

这是完整的解决方案：

public class CustomTextView extends AppCompatTextView {
    private static final int NOT_SET = -1;
    private static final int LEFT = 0;
    private static final int START = 0;
    private static final int TOP = 1;
    private static final int RIGHT = 2;
    private static final int END = 2;
    private static final int BOTTOM = 3;

    public CustomTextView(Context context) {
        super(context);
    }

    public CustomTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initAttrs(context, attrs);
    }

    public CustomTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initAttrs(context, attrs);
    }

    void initAttrs(Context context, AttributeSet attrs) {
        if (attrs == null) {
            return;
        }
        Drawable[] drawablesArr = getCompoundDrawables();

        TypedArray attributeArray = context.obtainStyledAttributes(attrs, R.styleable.CustomTextView);
        Drawable drawableStart = null;
        Drawable drawableEnd = null;
        Drawable drawableBottom = null;
        Drawable drawableTop = null;
        Drawable drawableLeft = null;
        Drawable drawableRight = null;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            drawableStart = attributeArray.getDrawable(R.styleable.CustomTextView_drawableStartCompat);
            drawableEnd = attributeArray.getDrawable(R.styleable.CustomTextView_drawableEndCompat);
            drawableBottom = attributeArray.getDrawable(R.styleable.CustomTextView_drawableBottomCompat);
            drawableTop = attributeArray.getDrawable(R.styleable.CustomTextView_drawableTopCompat);
            drawableLeft = attributeArray.getDrawable(R.styleable.CustomTextView_drawableLeftCompat);
            drawableRight = attributeArray.getDrawable(R.styleable.CustomTextView_drawableRightCompat);
        } else {
            final int drawableStartId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableStartCompat, NOT_SET);
            final int drawableEndId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableEndCompat, NOT_SET);
            final int drawableBottomId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableBottomCompat, NOT_SET);
            final int drawableTopId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableTopCompat, NOT_SET);
            final int drawableLeftId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableLeftCompat, NOT_SET);
            final int drawableRightId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableRightCompat, NOT_SET);

            if (drawableStartId != NOT_SET)
                drawableStart = AppCompatResources.getDrawable(context, drawableStartId);
            if (drawableLeftId != NOT_SET)
                drawableLeft = AppCompatResources.getDrawable(context, drawableLeftId);
            if (drawableEndId != NOT_SET)
                drawableEnd = AppCompatResources.getDrawable(context, drawableEndId);
            if (drawableRightId != NOT_SET)
                drawableRight = AppCompatResources.getDrawable(context, drawableRightId);
            if (drawableBottomId != NOT_SET)
                drawableBottom = AppCompatResources.getDrawable(context, drawableBottomId);
            if (drawableTopId != NOT_SET)
                drawableTop = AppCompatResources.getDrawable(context, drawableTopId);
        }

        drawableStart = (drawableStart != null ? drawableStart : drawablesArr[START]);
        drawableLeft = (drawableLeft != null ? drawableLeft : drawablesArr[LEFT]);
        drawableStart = (drawableStart != null ? drawableStart : drawableLeft);

        drawableEnd = (drawableEnd != null ? drawableEnd : drawablesArr[END]);
        drawableRight = (drawableRight != null ? drawableRight : drawablesArr[RIGHT]);
        drawableEnd = (drawableEnd != null ? drawableEnd : drawableRight);

        drawableBottom = (drawableBottom != null ? drawableBottom : drawablesArr[BOTTOM]);
        drawableTop = (drawableTop != null ? drawableTop : drawablesArr[TOP]);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            setCompoundDrawablesRelativeWithIntrinsicBounds(drawableStart, drawableTop, drawableEnd, drawableBottom);
        } else {
            setCompoundDrawables(drawableStart, drawableTop, drawableEnd, drawableBottom);
        }

        attributeArray.recycle();
    }
}

Answer 14

使用Vector Drawables使用

kotlin

 val drawable1 = VectorDrawableCompat.create(resources, R.drawable.ic_rb_username, theme)
        yourView.setCompoundDrawablesRelativeWithIntrinsicBounds( drawable1, null, null, null)

java

  Drawable drawable1 = VectorDrawableCompat.create(getResources(), R.drawable.ic_rb_username, getTheme());
        yourView.setCompoundDrawablesRelativeWithIntrinsicBounds( drawable1, null, null, null);

Answer 15

为了向后兼容，请使用：

TextViewCompat.setCompoundDrawablesRelativeWithIntrinsicBounds(textView, left, top, right, bottom)

Answer 16

我正在使用绑定适配器来解决此问题

@JvmStatic
@BindingAdapter("drawableSvgLeft")
fun addDrawableSvgLeft(textView: TextView,drawable: Drawable){
    textView.setCompoundDrawablesWithIntrinsicBounds(drawable,null,null,null)
}

@JvmStatic
@BindingAdapter("drawableSvgRight")
fun addDrawableSvgRight(textView: TextView,drawable: Drawable){
    textView.setCompoundDrawablesWithIntrinsicBounds(null,null,drawable,null)
}

并在我的布局中也以此方式使用

<TextView
  drawableSvgRight="@{@drawable/svg_ic_battle_trophy}"
  .....

可能是vectorDrawables.useSupportLibrary = true 默认配置是必需的

是否可以使用android：DrawableRight在Buttons和TextViews中使用VectorDrawable？
