问题
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。
我在用
- Gradle 1.5
- 支持库23.2('com.android.support:appcompat-v7:23.2.0')
我发现的是，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 {

buildToolsVersion "23.0.2"
defaultConfig {

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。)

由于谷歌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：
- 首先在应用程序"res / values / attrs.xml"的attrs.xml文件中添加自定义TextView属性：<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"/>
</声明-设置样式>
</资源> - 然后像这样创建自定义TextView类：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;
公共类CustomTextView扩展AppCompatTextView {
public CustomTextView(Context context){
超级(上下文);
}
public CustomTextView(Context context，AttributeSet attrs){
超级(环境，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);
}
//支持rtl
setCompoundDrawablesRelativeWithIntrinsicBounds(drawableStart，drawableTop，drawableEnd，drawableBottom);
attributeArray.recycle();
}
}
}
- 现在，你可以通过自定义属性在任何布局中轻松使用它：<YOUR_VIEW_PACKAGE.CustomTextView
android：id ="@ id / edt_my_edit_text"
机器人：layout_width = "WRAP_CONTENT"
机器人：layout_height = "WRAP_CONTENT"
app：drawableStartCompat ="@ drawable / your_vector_drawable"<！ - vector drawable - >
app：drawableEndCompat ="@ drawable / your_vector_drawable"<！ - vector drawable - >
app：drawableTopCompat ="@ drawable / your_vector_drawable"<！ - vector drawable - >
app：drawableBottomCompat ="@ drawable / your_vector_drawable"<！ - vector drawable - >
/>
你可以使用Button，EditText和RadioButton执行类似的操作，因为它们是从TextView派生的
希望这可以帮助 ：)

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>

我找到的最佳方式：
Drawable leftDrawable = AppCompatResources.getDrawable(this, R.drawable.ic_search);
search.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, null, null);
