大佬教程收集整理的这篇文章主要介绍了Android：活动对话框/对话框意外消失，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我有一个 tabactivity应用程序,每当我从我的引擎(NDK C代码)获得回调时,我都会显示一个对话框.当应用程序处于恢复状态时,我确保显示对话框.

收到引擎回调后,我启动了NetworkDownDialog活动,但这会导致对话框停留一秒然后消失.如果我使用Dialog或AlertDialog,也会发生同样的事情.最奇怪的是,失踪似乎是随机的(并不总是发生).

这是一个S3设备.这是怎么回事？

网络向下对话代码

public class NetworkDownDialog extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.network_down);
        Logger.d("NetworkDownDialog","----------onCreate-----------");
        registerReceiver(mNetworkDownReceiver,new IntentFilter("NetworkDown"));
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        unregisterReceiver(mNetworkDownReceiver);
        Logger.d("NetworkDownDialog","------onDestroy-------");
    }
    @Override
    protected void onResume() {
        super.onResume();
        Logger.d("NetworkDownDialog","------onResume-------");
    }
    @Override
    protected void onRestart() {
        super.onRestart();
        Logger.d("NetworkDownDialog","------onRestart-------");
    }
    @Override
    protected void onStart() {
        super.onStart();
        Logger.d("NetworkDownDialog","------onStart-------");
    }
    @Override
    protected void onStop() {
        super.onStop();
        Logger.d("NetworkDownDialog","------onStop-------");
    }
    @Override
    public void onBACkPressed() {
        Logger.d("NetworkDownDialog","------onBACkPressed Do nothing-------");
    }
    private BroadcastReceiver mNetworkDownReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context,Intent intent) {
            finish();
        }
    };
}

在日志中,这是我看到的：

在这种情况下,ActivityDialog在上述之后消失了.

为什么我的对话框消失了？我的C级本机代码中的内存损坏是否可能导致此问题？我在UI方面做错了吗？我完全陷入困境……

SurfaceFlinger删除了我的tabactivity.这会导致对话框删除吗？
