在菜单选择上隐藏android状态栏

Question

我正在尝试使用以下代码隐藏我的活动中的Android状态栏：

创建代码：

    // 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);
}

状态栏隐藏，直到我选择菜单（菜单下面的代码）：

@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，直到我强行恢复电源关闭/开启或循环离开我的活动。

有人可以提供如何通过菜单通胀/选择隐藏状态栏的建议吗？

感谢;

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)
        }
}
