'How to hide the title bar through code in android

I want to hide the title bar using code for some of my activities.

I have used the following code

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                          WindowManager.LayoutParams.FLAG_FULLSCREEN);

the second line is working for full screen but it shows the application title. Lets say for my splash screen i want to hide my title. The 1st line of code crashes my application. Please help me if we can do it using code.

thanks.

Solution 1:^[1]

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

You should call this before your setContentView() method, did you do that?

You could always do it in your manifest by adding android:theme="@android:style/Theme.NoTitleBar" to your activity

If you are using API 11 and above

ActionBar actionBar = getActionBar();
actionBar.hide(); // slides out
actionBar.show(); // slides in

Solution 3:^[3]

for remove Application Titlebar then add this line

requestWindowFeature(Window.FEATURE_NO_TITLE);

before setContentView(R.layout.main);

Solution 4:^[4]

Make sure you are calling setContentView after these 2 lines

Solution 5:^[5]

Update for 2022. Works in Android 9+ (at least) and you can call it after setContentView()

// Hide action bar Objects.requireNonNull(getSupportActionBar()).hide();

// Show action bar Objects.requireNonNull(getSupportActionBar()).show();
