如何在android中直接比较两个图像背景

Question

嗨，我在这里做一个应用程序，我需要比较图像背景。当图像背景不同意味着我需要翻转这些图像，图像背景相同意味着我需要停止动画。我尝试使用下面的代码，但我翻转图像。但我不知道当图像背景相同时如何停止这些图像翻转动画。在这里我需要提供自定义背景，因此为 3 张图片拍摄了 6 张图片。请任何人帮助我......

Answer 1

尝试将 Drawable 改为 Bitmap 对象

Bitmap bitmap = ...;
Bitmap bitmap1 = ...;

if(bitmap == bitmap2)
{
    //Your Toasts
}

转换示例：

Drawable myDraw = view.getBackground();
Bitmap bitmap = ((BitmapDrawable)myDraw).getBitmap();

Answer 2

 i1=(ImageView)findViewById(R.id.imageView1);
 i2=(ImageView)findViewById(R.id.imageView2);

 Drawable d=i1.getDrawable();
 Drawable d1=i2.getDrawable();
 if( d == d1){
     Toast.makeText(Example.this, "hello", Toast.LENGTH_SHORT).show();
 }else {
    Toast.makeText(Example.this, "hai", Toast.LENGTH_SHORT).show();
 }
