Question

我正在尝试使用Android Studio 2.2预览1，但如果我创建一个新项目并添加一个简单的EditText并尝试运行，则会出现以下错误。

我的布局是

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/content_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="br.com.tutorialandroid.sqlite.MainActivity"
    tools:showIn="@layout/app_bar_main"
    tools:layout_editor_absoluteX="0dp"
    tools:layout_editor_absoluteY="81dp">

    <EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:inputType="textPersonName"
    android:text="Nome"
    android:ems="10"
    tools:layout_editor_absoluteX="84dp"
    tools:layout_editor_absoluteY="262dp"
    android:id="@+id/txtNome"
    app:layout_constraintLeft_toLeftOf="@+id/content_main"
    tools:layout_constraintLeft_creator="0"
    app:layout_constraintTop_toTopOf="@+id/content_main"
    tools:layout_constraintTop_creator="0"
    app:layout_constraintRight_toRightOf="@+id/content_main"
    tools:layout_constraintRight_creator="0"
    app:layout_constraintBottom_toBottomOf="@+id/content_main"
    tools:layout_constraintBottom_creator="0" />

</android.support.constraint.ConstraintLayout>

我的build.gradle（模块级别）文件是

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    defaultConfig {
        applicationId "br.com.tutorialandroid.sqlite"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:design:23.4.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha1'
    testCompile 'junit:junit:4.12'
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
    androidTestCompile 'com.android.support.test:runner:0.5'
    androidTestCompile 'com.android.support:support-annotations:23.4.0'
}

和我的build.gradle（应用程序级别）文件是

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0-alpha1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这是我在AS 2.2预览1中的布局预览

Answer 1

经过真正的斗争，这似乎是一个问题。降级从2.2.0-alpha1到稳定版本（2.1对我有用）。

因此，请更改build.gradle（应用级别）并同步：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Answer 2

这似乎有关，但我遇到了一个问题，即edittexts导致Samsung Tab 4崩溃，但似乎在其他所有设备上运行正常。最后发现缺少 /res/drawable-v21/abc_edit_text_material.xml ，所以我从之前的sdk中获取 abc_edit_text_material.xml 并添加到我的项目中，直到所有的bug来自即将推出的Gradle插件。

Answer 3

无需降级只需创建一个扩展EditText的子类。例如：

public class Text extends EditText {
    public Text(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
}

然后在EditText

的xml文件中使用此类

<com.example.edittextproblem.Text
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="haha"/>

你的问题将得到解决：）
