无法解决方法getwidth和getHeight

Question

我的错误无法解决方法getWidth();和getHeight()相同; 我还是Android工作室的新手，所以请给我一些懈怠，请向我解释。

注意，第二个canvas.scale是我发现的添加代码应该是解决方案以获得屏幕分辨率。

这是我的代码

       private void draw(){
           if(visible){
               Canvas canvas= holder.lockCanvas();
               canvas.save();


               movie.draw(canvas, -100, 0);
               canvas.restore();
               holder.unlockCanvasAndPost(canvas);
               movie.setTime((int) (System.currentTimeMillis() % movie.duration()));
               handler.removeCallbacks(drawGif);
               handler.postDelayed(drawGif,frameDuration);

           }
       }



    @Override
    public void onVisibilityChanged(boolean visible) {
        super.onVisibilityChanged(visible);
        this.visible=visible;
        if(visible){
            handler.post(drawGif);
        } else {
            handler.removeCallbacks(drawGif);
        }
    }


    @Override
    public void onDestroy() {
        super.onDestroy();
    }



}

}

您可以使用画布代替上下文

 canvas.scale((float)canvas.getWidth() / (float)movie.width(),(float)canvas.getHeight() /      (float)movie.height());
