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？
