我有以下视图类:
public class MyHorizontalViewIndicator extends View{
protected synchronized void onDraw(Canvas canvas) {
super.onDraw(canvas);
Paint paint = new Paint();
paint.setTextSize(30);
canvas.drawText("Test",90, 90, paint);
}
}
<com.my.myview.MyHorizontalViewIndicator
android:id="@+id/view_indicator"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layoutDirection="inherit"/>
当语言为英语时,(LTR)测试消息显示正常,但是,当我将语言更改为阿拉伯语(RTL)时,画布不会显示。

在Manifest.xml中,您添加了android:supportsRtl
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
将此行canvas.drawText("Test",90, 90, paint);
更改为
canvas.drawText("Test",bound.top-100, bound.left-100, paint);
尝试绘制文本的负值
并在xml中更改并尝试layoutDirection = LOCALE
