java - 无法在 AlertDialog/LoginDialog 期间隐藏导航栏

Question

我试图通过运行 Android 4.2.2 的应用程序全局隐藏导航栏

我已经成功地使用了以下(公认的 hackish)方法来实现:

getWindow().getDecorView().setSystemUiVisibility(8);

它成功地删除了导航栏(事实上它是 hackish 非常好 - 这是用于信息亭所以它只会安装在有限数量的设备上)

现在，我正尝试删除 MainActivity 以外其他地方的导航栏 - 例如当它在 AlertDialog/LoginDialog 期间重新出现时。

我正在尝试使用:

public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(getActivity(),R.style.HoloDarkDialog));
    LayoutInflater inflater = getActivity().getLayoutInflater();

    variables = SingletonVariables.getInstance();

    view = inflater.inflate(R.layout.login, null);
    EditText userEditText = (EditText) view.findViewById(R.id.loginUserIdEditText);
    getWindow().getDecorView().setSystemUiVisibility(8);

但是这会导致错误:

The method getWindow() is undefined for the type LoginDialog

有谁知道可以避免这种情况的方法吗？

编辑:(额外请求的源代码)

// Function to handle show dialog
public void showLogin(View view, String whichActivity) {
    pd = new ProgressDialog(this.getApplicationContext());
    pd.setMessage("Logging in, Please wait....");

    LoginDialog logindialog = new LoginDialog();
    logindialog.setWhichActivity(whichActivity);
    logindialog.show(getFragmentManager(), "MyLogin");
}

Answer 1

试试这段代码

@Override
public void show() {
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    super.show();
    int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_FULLSCREEN;
    this.getWindow().getDecorView().setSystemUiVisibility(uiOptions);
    this.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);

}
