我尝试在我的清单文件中更改我的启动器活动。更改后,我再次重新设置了我的代码(重新编辑,以便它与以前一样)。所以我只是在我的活动之间复制粘贴这段代码
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
重置我的代码后,该应用无法打开。 我收到了一个错误
java.lang.IllegalArgumentException
:AppCompat不支持当前的主题功能,在我的setContentView(R.layout.activity_main)上停止;
我对这个问题感到非常沮丧,因为我没有在我的代码中更改任何内容(它在以前的工作中是不可思议的)
这是我的清单文件代码

You can easily change the main theme. Just modify application.android:theme attribute.
There are 8 main themes you can use:
Theme.CityGuide.Blue
Theme.CityGuide.Brown
Theme.CityGuide.Carrot
Theme.CityGuide.Gray
Theme.CityGuide.Green
Theme.CityGuide.Indigo
Theme.CityGuide.Red
Theme.CityGuide.Yellow
Don't forget to modify also MainActivity's theme.

答案 0 :(得分:0)
当我第一次使用API 23在android stdio中创建项目时,我遇到了类似的问题,因此要解决这些问题,请尝试进行一些更改。 请在第一行更改您的活动代码: -
public class MainActivity extends AppCompatActivity
这些: -
public class MainActivity extends Activity
当我遇到同样的问题时,它对我有用。
