我在某些用户的电话（例如Motorola Razr i）上收到“ nosuchmethod错误”，但在HTC上工作正常。下面是代码。
Drawable rBlack;
rBlack = getResources().getDrawable(R.drawable.rblack, getTheme());
和Stacktrace：

如果我使用此代码：
flipButton.setImageDrawable(getDrawable(R.drawable.rblack));
我得到这个错误

我敢打赌，它getDrawable(R.drawable.rblack, getTheme());在API 21中添加的失败。将该行更改为：
if(android.os.Build.VERSION.SDK_INT >= 21){
rBlack = getResources().getDrawable(R.drawable.rblack, getTheme());
} else {
rBlack = getResources().getDrawable(R.drawable.rblack);
}
