You need to use a Theme.AppCompat theme (or descendant) with this activity
来源:互联网 发布:我的世界0.15天堂js 编辑:程序博客网 时间:2024/05/16 04:40
问题现象:
只要添加android:theme="@android:style/Theme.Black.NoTitleBar",APP就会闪退。
错误log:
java.lang.RuntimeException:Unable to start activityComponentInfo{com.example.test2/com.example.test2.MainActivity}:java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (ordescendant) with this activity.
原因:
从错误提示中提到Theme.AppCompat theme,这是因为我们的activity一定是继承了兼容包中的类,
比如我这里就无意中继承了ActionBarActivity,它来自android.support.v7.app.ActionBarActivity。
所以就要使用与其配合的AppCompat的theme才行。
解决方法:
解决两种:
1.根据提示来使用AppCompat的theme,如下:
[html] view plaincopy
- <activity
- android:name=".MainActivity"
- android:theme="@style/Theme.AppCompat.Light.NoActionBar"
- android:label="@string/app_name" >
不过我要设置全屏,但我并没有找到,所以虽然错误不见了,但并没有达到我的预期。
2.如果不是那么强烈需要继承自ActionBarActivity,就直接继承Activity吧。问题自然搞定!
