在调用onStop（）之后导航到活动

Question

When onPause is called, the Dialog is shown and it's background it's transparent so application behind is visible. So if I press Home button while Dialog is shown and then navigate back to application it shows Dialog with black background, if I dismiss Dialog application continuous normally. So how do I make background visible after navigating to application. Black background only happens when I press Home button so application is not visible. I'm guessing that something strange happens in onStop method...

This is how I call my Dialog:

pauseMenu = new PauseMenu();
pauseMenu.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
pauseMenu.show();

And onCreate from Dialog class:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.pause_menu);

    }

Answer 1

Your dialog is recreated automatically, so

pauseMenu.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

is not called. So, try to call this set in your onCreate() after calling super.onCreate()
