Override the onBackPressed()of your activity
覆盖onBackPressed()您的活动
@SuppressLint("MissingSuperCall")
@Override
public void onBackPressed()
{
// super.onBackPressed(); // Comment this super call to avoid calling finish() or fragmentmanager's backstack pop operation.
}
You may suppress lint's error by adding @SuppressLint("MissingSuperCall")as per Matthew Read pointed out.
您可以通过@SuppressLint("MissingSuperCall")按照 Matthew Read 指出的添加来抑制 lint 的错误。

This way works for all versions of Android, and will work with libraries that may override the default functionality in their Activities(such as cocos2d-x):
这种方式适用于所有版本的Android，并且适用于可能覆盖其默认功能的库Activities（例如cocos2d-x）：
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
return (keyCode == KeyEvent.KEYCODE_BACK ? true : super.onKeyDown(keyCode, event));
}
