使用 TransitionDrawable 動畫檢視背景顏色(開關顏色)

public void setCardColorTran(View view) {
   ColorDrawable[] color = {new ColorDrawable(Color.BLUE), new ColorDrawable(Color.RED)};
   TransitionDrawable trans = new TransitionDrawable(color);
    if(Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN) {
        view.setBackgroundDrawable(trans);
        }else {
        view.setBackground(trans);
    }
    trans.startTransition(5000);
}
