Android studio inherits AppCompatActivity and the title bar is hidden.

Android studio inherits AppCompatActivity and the title bar is hidden.

In the official version of android studio 1.5.1, the newly created activity inherits AppCompatActivity, but when we hide the title bar and use code again, it will cause a crash. The Code is as follows:

RequestWindowFeature (Window. FEATURE_NO_TITLE );

The method we used is in setContentView (R. layout.Activity_navigation) Previously used. It can be used normally under the inherited standard Activity.

If AppCompatActivity is inherited, it must be changed to setContentView (R. layout.Activity_navigation,

Use the following code:

Getsuppactionactionbar (). hide ();

I will update it for specific reasons.
