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

该应用程序将编译良好，没有任何警告。

我在用

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

但我发现，我可以在 Java 中以编程方式分配 SVG，而不会发生这样的崩溃。

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。）

但是是否可以将 drawableRight 等用于 SVG 资产？

这是我的布局

可以对 SVG 资产使用 drawableRight 等吗？

是的

AppCompatTextView 现在支持app:drawableLeftCompat、app:drawableTopCompat、app:drawableRightCompat、app:drawableBottomCompat和复合可绘制对象，支持向后移植的可绘制类型app:drawableStartCompat，app:drawableEndCompat例如VectorDrawableCompat.

将此包含在您的 gradle 文件中

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

在您的文本视图中，您可以使用

app:drawableLeftCompat
app:drawableStartCompat

如果在按钮中使用 app:drawableLeftCompat、app:drawableStartCompat 时遇到问题，您需要将库更新为

androidx.appcompat:appcompat:1.2.0-alpha01

他们有一个错误

androidx.appcompat:appcompat:1.1.0-alpha01

你可以看到文档

或者，如果您还不想更新，那么：

因为 Google 似乎不会在短期内对这个问题采取任何措施，所以我不得不为我的所有应用想出一个更可靠的可重用解决方案：

  1. 首先在您的应用程序"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"/>
    </declare-styleable>
</resources>

  2. 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;

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();
        }
    }
}

  3. 现在，您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"
    android:layout_width="wrap_content"
    android: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 -->
    />
    • 您可以使用Button、EditText和RadioButton做类似的事情，因为它们派生自 TextView

希望这可以帮助 ：）

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

尝试将您的矢量可绘制对象包装到图层列表或选择器中：

<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>

为了补充这里的一些答案：您可以让 VectorDrawable 像drawableLeft（等）一样工作，但这取决于支持库版本，并且需要付出代价。

在哪些情况下有效？我已制作此图以提供帮助（对支持库 23.4.0 至 - 至少 - 25.1.0 有效）。

其他答案均无效，这是我将 a 添加VectorDrawable到 a 的方式TextView，您VectorDrawableCompat.create()在处理VectorDrawables以下内容时应使用Android L：

TextView titleTextView = (TextView) viewHolder.getView(android.R.id.text1);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
{
       Drawable leftDrawable = AppCompatResources
                            .getDrawable(context, R.drawable.ic_tickbox);
       titleTextView.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, null, null);
}
else
{
      //Safely create our VectorDrawable on pre-L android versions. 
       Drawable leftDrawable = VectorDrawableCompat
                            .create(context.getResources(), R.drawable.ic_tickbox, null);
       titleTextView.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, null, null);
}

可以直接在 xml 中设置矢量可绘制对象，但您必须包含数据绑定框架。

写吧

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

并将你的整个布局包装在一个<layout>标签中，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"
        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:background="@color/colorPrimary"
            android:drawableRight="@{@drawable/ic_accessible_white_36px}"
            android:text="Hello World!"
            android:textColor="#FFFFFF"
            android:textSize="22sp"/>
    </RelativeLayout>
</layout>

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

编辑：

当然，如果您想在 Lollipop 之前使用矢量可绘制对象，则必须使用启用支持矢量可绘制对象

vectorDrawables.useSupportLibrary = true

因此，您build.gradle需要 2 个新命令：

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

我浏览了所有答案并使用了最新的 Android Studio 3.0.1 和 AppCompat Support Library 26.1.0，我可以保证这一切正常。

在build.gradle (app) 文件中

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

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

并且在 Activity 扩展中AppcompatActivity包括这个外部方法，即一个static块

static {
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}

或者，如果您希望将其应用于整个应用程序，只需将此行包含在类扩展Application类中

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

我回答这个问题来得太晚了，因为我在这个问题上迟到了。我对带有 TextView 的 svg/vector drawables 有同样的问题。我可以使用以下两行代码来解决我的问题，而不是制作您自己的自定义可绘制对象：

Drawable drawableTop = AppCompatResources.getDrawable(view.getContext(), iconId);
view.setCompoundDrawablesWithIntrinsicBounds(null, drawableTop, null, null);

希望它会帮助你。

我为此设计了一个小型库 - textview-rich-drawable（它还支持定义复合绘图的大小和着色）。

<com.tolstykh.textviewrichdrawable.TextViewRichDrawable
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Some text"
    app:compoundDrawableHeight="24dp"

    app:drawableTopVector="@drawable/some_vector_drawble"
    app:drawableEndVector="@drawable/another_vector_drawable"

和依赖

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。像这样包装它们：

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

这会神奇地起作用，我还没有调查幕后发生的事情，但我猜 TextView 正在使用getDrawable来自AppCompatResources或类似的方法。

根据 Behzad Bahmanyar 的回答，我注意到我无法将 android 的正常属性用于普通 png 文件：

android:drawableTop
android:drawableBottom
etc

因为它将被替换为 null in

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

如果app:drawableTopCompat未设置，但android:drawableTop已设置（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;

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}"

为了向后兼容，请使用：

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

使用 Vector Drawable 使用

科特林

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

爪哇

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

我使用绑定适配器来解决这个问题

@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)
}

并在我的布局中以这种方式使用

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

可能需要默认配置中的 vectorDrawables.useSupportLibrary = true
