How to remove Alert dialog Title bar

If you don't want title bar in alert dialog then just remove below line from code.

dialogbuilder.setTitle("Login");

If still not working then add below line.

dialogbuilder.requestWindowFeature(Window.FEATURE_NO_TITLE);

Use dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

Use dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); before dialog.setContentView(R.layout.logindialog); by doing so you will be able to hide the Dialog's title.
