我试图使用按钮去另一个页面,但它总是失败.
这是我的头等舱与其XML：
public class FindPeopleFragment extends Fragment {
public FindPeopleFragment(){}
@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_home,container,false);
return rootView;
}
public void goToAttract(View v)
{
Intent intent = new Intent(getActivity().getApplication(),MainActivityList.class);
startActivity(intent);
}
}
这是我的XML：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true"
android:layout_marginBottom="48dp"
android:onClick="goToAttract"
android:text="Button" /></RelativeLayout>
这是我的堆栈跟踪.这是当我使用onclicklistener的结果

解决方法
用这个
public void goToAttract(View v)
{
Intent intent = new Intent(getActivity(),MainActivityList.class);
startActivity(intent);
}
确保你已经在你的清单中注册了MainActivityList
