我在扩展 ActionBarActivity 时遇到错误捕获。如果我扩展 Activity 则没有错误。
事情是在我的其他 Activity 中它完美地工作。起初，我认为这是因为我之前的 Activity 在 Intent 中加入了额外的东西。但即使没有它，应用程序也会崩溃。
这是我的代码:
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
public class FullscreenActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fullscreen);
}
}
编辑: 和日志结果:

最佳答案
根据您发布的错误:“您需要在此 Activity 中使用 Theme.AppCompat 主题(或后代)。”您应该将 appcompat 库用作库项目，在这种情况下，您将在该项目的 res/values 下看到可用的主题
