无法在AlertDialog /隐藏的LoginDialog导航栏 [英] Unable To Hide Navigation Bar during AlertDialog/LoginDialog

问题描述

我试图通过运行Android 4.2.2我的应用程序在全球隐藏导航栏

我已成功地使用实施以下（admitadly的hackish）方法：

。

  getWindow（）getDecorView（）setSystemUiVisibility（8）;
 

其中成功地消除了导航栏（事实上，它是hackish的是完全没有问题 - 这是一个售货亭所以它将仅仅在设备上的有限数量的被安装）

现在我试图删除导航栏比我MainActivity其他地方 - 比如当它AlertDialog /时的LoginDialog再次出现

我试图使用方法：

 公共对话框onCreateDialog（捆绑savedInstanceState）{
    AlertDialog.Builder建设者=新AlertDialog.Builder（新ContextThemeWrapper（getActivity（），R.style.HoloDarkDialog））;
    LayoutInflater吹气= getActivity（）getLayoutInflater（）。    变量= SingletonVariables.getInstance（）;    鉴于= inflater.inflate（R.layout.login，NULL）;
    的EditText userEditText =（EditText上）view.findViewById（R.id.loginUserIdEditText）;
    。getWindow（）getDecorView（）setSystemUiVisibility（8）。
 

不过这个结果在错误：

 的方法getWindow（）是未定义的类型函数LoginDialog
 

有谁知道这可能是可以避免的方法？

由于提前，

编辑：（附加要求源$ C ​​$ C）

  //函数来处理显示对话框
公共无效showLogin（查看视图，弦乐whichActivity）{
    PD =新ProgressDialog（this.getApplicationContext（））;
    pd.setMessage（登录，请稍候....）;    一个LoginDialog =的LoginDialog新一个LoginDialog（）;
    logindialog.setWhichActivity（whichActivity）;
    logindialog.show（getFragmentManager（），MyLogin）;
}

Smthng这样？

 查看decorView = getActivity（）getWindow（）getDecorView（）。
INT uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility（uiOptions）;
 

更新：
（来源：<一个href=\"http://stackoverflow.com/a/2844648/3464293\">http://stackoverflow.com/a/2844648/3464293)

在您LoginDialog.java添加这个方法：

  @覆盖
公共无效调用onStart（）{
super.onStart（）;
窗口窗口= getDialog（）getWindow（）。
window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
window.requestWindowFeature（Window.FEATURE_NO_TITLE）;
INT uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN;
。window.getDecorView（）setSystemUiVisibility（uiOptions）;
}
 

和尝试呢。删除previous更新。

I'm attempting to hide the navigation bar globally through my app running Android 4.2.2

I have managed to use the following (admitadly hackish) method of implementing:

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

Which successfully removes the Navigation bar (the fact it is hackish is perfectly fine - this is for a kiosk so it will only be installed on a limited number of devices)

Now I'm attempting to remove the navigation bar in places other than my MainActivity - such as when it reappears during a AlertDialog/LoginDialog.

I'm attempting to use:

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);

However this result in the error:

The method getWindow() is undefined for the type LoginDialog

Does anyone know of a way this might be avoided?

Thanks in advance,

A.A.

Edit: (additional requested source code)

// 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");
}

解决方案

Maybe this can help you? http://stackoverflow.com/a/23435922/3464293

Smthng like this?

View decorView = getActivity().getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

Update: (source: http://stackoverflow.com/a/2844648/3464293)

In your LoginDialog.java add this method:

@Override
public void onStart() {
super.onStart();
Window window = getDialog().getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
window.requestWindowFeature(Window.FEATURE_NO_TITLE); 
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN; 
window.getDecorView().setSystemUiVisibility(uiOptions);
}

and try then. Remove previous updates.
