How to hide Title Bar of a pop-up activity

Question

I created an activity which is shown as pop up/ Dialog by following answers given in this question .

I did it by adding these lines in AndroidManifest

 <activity
        android:name=".package.Activity"
        android:theme="@style/Theme.AppCompat.Light.Dialog.Alert" />

It works well as intended but the problem it shows Appname as title. I want to make it appear as AlertDialog. How to fix this?

I also cant use setTitle("") or label="" because empty space is left where appname was before.

Answer 1

您可以在Activity中简单地调用setTitle("")函数。

Answer 2

Add this code to the top of the onCreate() method of the Activity:

setTheme(R.style.{style}

• The {style} should be ended with NoActionBar . ie R.style.Theme_AppCompat_NoActionBar

• And most importantly, add the code before these two lines of code (add it to the top of the method):

   super.onCreate(savedInstanceState); setContentView(R.layout.{your layout}); 

Hope this answer helped!
