问题描述

I start from activity A->B->C->D->E ..when i go from D->E there should be no activity in stack but, the user can use back button from D and go to C (without refreshing Activity C, like normal back function)
推荐答案
您可以添加一个的BroadcastReceiver
在要关闭(A,B,C,D的所有活动):
You could add a BroadcastReceiver
in all activities you want to close (A, B, C, D):
public class MyActivity extends Activity {
private FinishReceiver finishReceiver;
private static final String ACTION_FINISH =
"com.mypackage.MyActivity.ACTION_FINISH";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
finishReceiver= new FinishReceiver();
registerReceiver(finishReceiver, new IntentFilter(ACTION_FINISH));
}
@Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(finishReceiver);
}
private final class FinishReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_FINISH))
finish();
}
}
}
......,并通过调用关闭它们...
... and close them by calling ...
sendBroadcast(new Intent(ACTION_FINISH));
...在活动E.检查this很好的例子的了。
