DialogFragment添加警告窗口

Question

我有觸發時的功能後沒有顯示，成功地顯示與下面的代碼DialogFragment

DialogFragment

DialogFragment dialog; 
View dialogView; 
Context activityContext; 

... 

dialog = new DialogFragment(){ 
    @Override public Dialog onCreateDialog(Bundle savedInstanceState) { 
     dialogView = getActivity().getLayoutInflater().inflate(R.layout.customView, null); 
     ... 
     AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 
     builder.setView(dialogView); 
     return builder.create(); 
    } 
}; 

dialog.show(activityContext.getSupportFragmentManager() , "MyDialog"); 

的問題是，我添加了一個系統警報後，窗口中的DialogFragment不再顯示，但是如果我傳遞給另一個應用程序，當我的應用程序最小化時，我可以看到DialogFragment，同時減小它的大小

系統警報窗口

WindowManager mWindowManager; 
WindowManager.LayoutParams params; 

... 

mWindowManager = (WindowManager)activityContext.getSystemService(Context.WINDOW_SERVICE); 
params = new WindowManager.LayoutParams(
    WindowManager.LayoutParams.WRAP_CONTENT, 
    WindowManager.LayoutParams.WRAP_CONTENT, 
    WindowManager.LayoutParams.TYPE_PHONE, 
    WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, 
    PixelFormat.TRANSLUCENT 
} 
params.gravity = Gravity.CENTER_VERTICAL | Gravity.RIGHT; 
addView(((LayoutInflater)activityContext.getSystemService("layout_inflater")).inflate(R.layout.floatingBotton, null)); 

所以......爲什麼我不能看到我的對話框頂部（據我瞭解，在對話框中顯示） 爲什麼當系統警告窗口時纔會發生顯示

我和其他標誌的系統警告窗口試過，但我有，我試過的那些同樣的問題

Answer 1

FragmentManager fmg1=this.getChildFragmentManager(); 
//or 
FragmentManager fmg1=this.getFragmentManager(); 

dialog.show(fmg1 , "MyDialog"); 

請試試這個可能有用
