隱藏Android狀態欄中

Question

我嘗試使用下面的代碼隱藏我的活動android的狀態欄：

的OnCreate代碼：

// set as full screen 
    View decorView = getWindow().getDecorView(); 
    // Hide the status bar. 
    int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN; 
    decorView.setSystemUiVisibility(uiOptions); 

protected void onResume() { 
    super.onResume(); 
    // set as full screen 
    View decorView = getWindow().getDecorView(); 
    // Hide the status bar. 
    int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN; 
    decorView.setSystemUiVisibility(uiOptions); 
} 

protected void onWindowFocusChanged() { 
    // set as full screen 
    View decorView = getWindow().getDecorView(); 
    // Hide the status bar. 
    int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN; 
    decorView.setSystemUiVisibility(uiOptions); 
} 

的狀態欄隱藏，直到我選擇菜單（下面的代碼菜單）：

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    if (item.getItemId() == R.id.help) { 
     homehelp = 0; // reset the homehelp logic 
     homehelp(); // call it to display 
    } 
    return false; 
} 

任何使菜單膨脹的選項都會顯示狀態欄 - 狀態欄會一直保留，直到我使用電源關閉/打開或騎自行車離開我的活動強制執行簡歷。

有人可以提供一個建議如何保持與菜單通貨膨脹/選擇隱藏狀態欄？

謝謝;

嘗試

public boolean onOptionsItemSelected(MenuItem item) { 
    if (item.getItemId() == R.id.help) { 
     homehelp = 0; // reset the homehelp logic 
     homehelp(); // call it to display 
    } 

    // set as full screen 
    View decorView = getWindow().getDecorView(); 
    // Hide the status bar. 
    int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN; 
    decorView.setSystemUiVisibility(uiOptions); 

    return false; 
}

嘗試

public void onWindowFocusChanged(boolean winChange){ 
     super.onWindowFocusChanged(winChange); 

     if(winChange){ 
      View decorView = getWindow.getDecorView(); 
      int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN; 
      decorView.setSystemVisibility(uiOptions) 
     } 
}
