我试图用 "按钮 "转到另一个页面,但总是失败。
下面是我的第一类和它的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);
}
}
这里是我的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,这是我使用onclicklistener时的结果。

试试这个代码,一次-
public class FindPeopleFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_home,
container, false);
Button button = (Button) rootView.findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
updateDetail();
}
});
return rootView;
}
public void updateDetail() {
Intent intent = new Intent(getActivity(), MainActivityList.class);
startActivity(intent);
}
}
按照Raghunandan的建议,从你的fragment_home.xml
中删除以下代码
android:onClick="goToAttract"
删除此内容
android:onClick="goToAttract"
然后
View rootView = inflater.inflate(R.layout.fragment_home, container, false);
Button b = (Button)rootView.findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
Intent intent = new Intent(getActivity(), MainActivityList.class);
startActivity(intent);
}
});
return rootView;
错误说你需要在活动类中`public void goToAttract(View v)'。
Could not find method goToAttract(View) in the activity class
原因请查看PareshMayani的回答@@。

编辑:
Caused by: java.lang.OutOfMemoryError
我猜你的图片太大,无法装入,需要缩小。因此出现了 "OutOfMemoryError"。
