我想知道如何在Android Studio上檢查imageview的顏色

Question

這就是我現在所擁有的，但是每次都錯了

if(ivBall.equals(Color.RED))
        {
            Toast.makeText(getApplicationContext(), "good", Toast.LENGTH_SHORT).show();
        }
        else
        {
            Toast.makeText(getApplicationContext(), "wrong", Toast.LENGTH_SHORT).show();
        }

將顏色設置為ImageView：

ivBall.setBackgroundColor(Color.RED);

嘗試使用此：

    ColorDrawable drawable = (ColorDrawable) ivBall.getBackground();
    if(drawable.getColor() == Color.RED)
    {
        Toast.makeText(getApplicationContext(), "good", Toast.LENGTH_SHORT).show();
    }
    else
    {
        Toast.makeText(getApplicationContext(), "wrong", Toast.LENGTH_SHORT).show();
    }
