Question

我有一个VectorDrawable xml，在为android创建一个watch face时，在onDraw（Canvas canvas，Rect bounds）方法中，我可以绘制这个vectorDrawable吗？像canvas.draw（vector.xml），我不知道如何，请帮助！

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:height="64dp"
    android:width="64dp"
    android:viewportHeight="600"
    android:viewportWidth="600" >
    <group
        android:name="rotationGroup"
        android:pivotX="300.0"
        android:pivotY="300.0"
        android:rotation="45.0" >
        <path
            android:name="v"
            android:fillColor="#000000"
            android:pathData="M300,70 l 0,-70 70,70 0,0 -70,70z" />
    </group>
</vector>

以下是WatchFaceService.Engine的简单代码

private class Engine extends CanvasWatchFaceService.Engine {

    private Drawable mVectorDrawable;

    @Override
    public void onCreate(SurfaceHolder holder) {
        super.onCreate(holder);
        ...
        Resources resources = FooBarWatchFace.this.getResources();
        mVectorDrawable =resources.getDrawable(R.drawable.rounded);
    }

    @Override
    public void onDraw(Canvas canvas, Rect bounds) {
        int width = bounds.width();
        int height = bounds.height();
        ...
        mVectorDrawable.setBounds(0,0,width,height);
        mVectorDrawable.draw(canvas);
    }
}

Android CanvasWatchFaceService.Engine onDraw绘制一个向量xml
