当尝试请求无倾斜条时，应用程序崩溃

Question

当我尝试请求没有标题栏时，应用程序崩溃了

super.onCreate (savedInstanceState);this.requestWindowFeature (Window.FEATURE_NO_TITLE);this.getWindow () .setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);setContentView (R.layout.activity_main);

---

Answer 1

在style.xml中编写以下代码:

<style name="NoAB" parent="Theme.AppCompat.Light.NoActionBar"></style>

并将此主题应用于要隐藏操作栏的活动

<activity
            android:name=".<YourActivity>"
            android:theme="@style/NoAB" >

Answer 2

在super.onCreate(savedInstanceState)之前调用this.requestWindowFeature(Window.FEATURE_NO_TITLE)
