有没有办法让一个像素的颜色表示（X，Y），并检查它的红色，如果是红色的，然后送触摸事件。

Is there a way to get color of a pixel say (x,y) and check if its red and if it is red then send a touch event.

我希望它在后台运行，它应始终检查像素（X，Y）的颜色，只要它变为红色，触摸事件进行仿真。

I want it to run in background and it should always be checking the color of that pixel (x,y) and as soon as it turns red , a touch event should be simulated.

推荐答案

您可以从下面的例子中得到的值。

You can get values from the following example.

final Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap();
imageView.setOnTouchListener(new OnTouchListener(){
        @Override
        public boolean onTouch(View v, MotionEvent event){
            int x = (int)event.getX();
            int y = (int)event.getY();
            int pixel = bitmap.getPixel(x,y);


            int red = Color.red(pixel);
            int blue = Color.blue(pixel);
            int green = Color.green(pixel);        
            return false;
        }
   });
