为什么AppTheme.NoActionBar无法正常工作? [英] Why is AppTheme.NoActionBar not working?
问题描述
我已经在Android Studio中创建了一个Android应用,并且默认情况下它创建了以下样式:
I've created an Android app in Android Studio, and it has created these styles by default:
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
但是,在一个活动中,我尝试将其设置为主题:
However, in an activity, I try to set this as a theme:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
...
android:theme="@style/AppTheme.NoActionBar">
但是当我运行该应用程序时,我会看到操作栏:
But when I run the app I'm getting the action bar:
我为什么要获得操作栏?我是不是做错了明显的事情,还是Google Studio本身的平台的官方IDE Android Studio试图混淆/误导其开发人员?
Why am I getting an action bar? Am I doing something obviously wrong, or is Android Studio, Google's official IDE for it's own platform, trying to confuse/mislead its developers?
这是我的活动代码,其中没有任何内容可以导致操作栏单独显示:
Here is my activity code, there's nothing in it that can cause the action bar to appear by itself:
public class WelcomeActivity extends AppCompatActivity {
@Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
setContentView(R.layout.activity_welcome);
}
}
推荐答案
尝试如下操作:
<style name="AppTheme.NoActionBar">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>
</style>
,并将其设置为清单中活动的主题,即:
and set this as the theme of your activity in the manifest, that is:
<activity
...
android:theme="@style/AppTheme.NoActionBar">
</activity>
