Question

我在MainActivity中使用NavigationView。现在，我的应用程序在Android 5.0及更高版本中正常运行。但是，它并没有在Android 4.0.4中运行。它在XML中显示<NavigationView />错误。

我认为应该有所帮助，而不是添加multidex支持。但是，它没有。

目前我在NavigationView＆amp; header_layout中的1个启动器图标。所以，我认为不应该OutOfMemoryError。

这是我的代码

的build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.gripxtech.kasimrangwala.unipayretailer"

        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:cardview-v7:23.1.1'

    compile 'com.squareup.okhttp:okhttp:2.7.0'
    compile 'org.apache.commons:commons-lang3:3.4'
    compile project(':materialdatetimepicker-library')
}

activity_main.xml中

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

        android:layout_width="match_parent"

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        app:headerLayout="@layout/nav_header"
        app:menu="@menu/nav_main" />

</android.support.v4.widget.DrawerLayout>

我无法弄清楚该怎么做。谢谢你提前。

Answer 1

最后，我找到了它。

首先，这是我的nav_header.xml文件。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="@dimen/nav_header_height"
    android:background="@drawable/side_nav_bar"
    android:gravity="bottom"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:theme="@style/ThemeOverlay.AppCompat.Dark" >

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:contentDescription="@string/app_name"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        android:src="@mipmap/ic_launcher" />

    <TextView
        android:id="@+id/tvNavUserFullName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        android:text="@string/nav_title"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

    <TextView
        android:id="@+id/tvNavUserBalance"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/nav_sub_head" />

</LinearLayout>

现在，专注于线号。 5。 android:background="@drawable/side_nav_bar" 它只不过是梯度。

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:angle="135"
        android:endColor="?attr/colorPrimaryDark"
        android:startColor="?attr/colorPrimary"
        android:type="linear" />
</shape>

我改变了这样的颜色值。

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:angle="135"
        android:endColor="@color/primary_dark"
        android:startColor="@color/primary"
        android:type="linear" />
</shape>

现在，它正在Android 2.3.3仿真器上运行。希望这将有助于将来的一些人。谢谢大家。

确保您对Android设计支持库具有正确的依赖关系。选择错误的一个很容易 - 因为Google似乎发布了两个不同的依赖字符串：

在此回答时，Android developer blog（以及用户hungryghost的注释）具有正确的依赖关系字符串，而Support library主页上的依赖关系字符串不起作用。

使用这个：compile＆＃39; com.android.support：design：22.2.0＆＃39;

请注意，版本是22.2.0（错误：22.0.0），并且该包名为design（错误：support-design）

完成这些更改后，请使用Android Studio菜单＆＃34;重建项目＆＃34;或＆＃34;同步＆＃34;更改gradle文件后有时会出现的按钮。
