隐藏Android状态栏中

Question

我尝试使用下面的代码隐藏我的活动android的状态栏：

的OnCreate代码：

// 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); 
} 

的状态栏隐藏，直到我选择菜单（下面的代码菜单）：

@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; 
} 

任何使菜单膨胀的选项都会显示状态栏 - 状态栏会一直保留，直到我使用电源关闭/打开或骑自行车离开我的活动强制执行简历。

有人可以提供一个建议如何保持与菜单通货膨胀/选择隐藏状态栏？

谢谢;

尝试

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; 
}

尝试

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

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