显示标题栏

Question

我有一个应用程序，可以在全屏和普通屏幕之间切换以适应特定条件。 我已经成功地完成了这个通知，但是在我将其从全屏恢复到正常屏幕模式后，TITLE BAR仍然保持隐藏状态。那么如何在隐藏它后显示标题栏？

编辑：

我所遇到的答案，他们做一个自定义标题栏并将其可见性之间进行切换，但是那不是我想要的。

CODE：

if(ScreenReceiver.wasScreenOn) { 
    Toast toast=Toast.makeText(this, "screen was on", Toast.LENGTH_LONG); 
    toast.show(); 
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN); 
    setContentView(R.layout.resume); 
} else { 
    Toast toast=Toast.makeText(this, "screen was off", Toast.LENGTH_LONG); 
    toast.show(); 
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN); 
    setContentView(R.layout.main); 
} 

Answer 1

试试这个

this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
           WindowManager.LayoutParams.FLAG_FULLSCREEN); 


/// custom tittle bar declaration 
final boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 

/// custom tittle bar creation ///.... 
    if (customTitleSupported) { 
     getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.tittle_bar); 
    } 
    final TextView myTitleText = (TextView) findViewById(R.id.title_bar); 
    if (myTitleText != null) { 
     myTitleText.setText("Categories"); 
    }
