所以我在图像视图上做一些旋转和翻译。据我了解,图像视图在其中任何一个之后都不是真正位于新位置,您必须在动画完成后将其实际移动到那里。所以我试图移动的图像视图被称为令牌,它被设置在它的原始位置并token.getLocationOnScreen( tokenPos );有它的起始位置。移动或平移后,我调用resetToken以处理移动或旋转。这似乎在一半的时间内完成了预期的结果......不确定我做错了什么,但它与它面对我想要的方式不一致。

public void resetToken() {   
    //Decode Image using Bitmap factory.
    Bitmap bMap = Bitmap.createBitmap(token.getDrawingCache());

    Matrix matrix = new Matrix();
    matrix.postRotate(0);

    //move the token to the spot it needs to be in
    //after an animation the token is not really
    //in the new spot
    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(token.getWidth(), token.getHeight());
    lp.setMargins(tokenPos[0], tokenPos[1], 0, 0);

    //Create bitmap with new values.
    Bitmap bMapRotate = Bitmap.createBitmap(bMap, 0, 0, token.getWidth(), token.getHeight(), matrix, true);
    token.setImageBitmap(bMapRotate);
    token.setLayoutParams(lp);
    //put rotated image in ImageView.


    moveCounter = moveCounter + 1;

}

我能够做到这一点。

public void resetToken() {   

    Bitmap bmpOriginal = BitmapFactory.decodeResource(this.getResources(), R.drawable.robo);
    Bitmap bmResult = Bitmap.createBitmap(bmpOriginal.getWidth(), bmpOriginal.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas tempCanvas = new Canvas(bmResult); 
    tempCanvas.rotate(currentMapDirection, token.getWidth(), token.getHeight());
    tempCanvas.drawBitmap(bmpOriginal, 0, 0, null);

    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(token.getWidth(), token.getHeight());
    lp.setMargins(tokenPos[0], tokenPos[1], 0, 0);

    token.setLayoutParams(lp);

    token.setImageBitmap(bmResult);


}
