method does not override method from its superclass . Android Fragment
提问by pmipmi
fragment1:
片段1：
public class fragment1 extends Fragment implements View.OnClickListener {
ImageButton but, but1, but2;
ImageView view;
@Override << this one
public View OnCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View myView = inflater.inflate(R.layout.fragment1, null);
but = (ImageButton) myView.findViewById(R.id.imageButton11);
but.setOnClickListener(this);
but1 = (ImageButton) myView.findViewById(R.id.imageButton1);
but1.setOnClickListener(this);
but2 = (ImageButton) myView.findViewById(R.id.imageButton2);
but2.setOnClickListener(this);
return myView;
}
@Override
public void onClick(View v) {
main xxx = (main)getActivity();
switch (v.getId()) {
case R.id.imageButton11:
xxx.str="but1";
break;
..
}}
main:
主要的：
Fragment frag1 = new fragment1();
fr1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
fTrans = getFragmentManager().beginTransaction();
fTrans.replace(R.id.frameLayout2, frag1);
fTrans.addToBackStack(null);
fTrans.commit();
}
});
method does not override method from its superclass in fragment1(first override) but without "implemets View.OnClickListener" it works
方法不会在fragment1（第一次覆盖）中覆盖其超类中的方法，但没有“实现View.OnClickListener”它可以工作

Spelling mistake. Name the method onCreateViewinstead of OnCreateView.
拼写错误。命名方法onCreateView而不是OnCreateView.

I am not familiar with the android sdk but I think you need something like this
我对 android sdk 不熟悉，但我认为你需要这样的东西
Fragment frag1 = new fragment1(){
@Override
public void onClick(View view) {
fTrans = getFragmentManager().beginTransaction();
fTrans.replace(R.id.frameLayout2, frag1);
fTrans.addToBackStack(null);
fTrans.commit();
}
};

return your inflated view
返回你膨胀的视图
public View onCreateView(.....) {
...
...
return InputFragmentView;
}
and change OnCreateView to onCreateView. you can tap ctrl+o to get it ready ^^
并将 OnCreateView 更改为 onCreateView。你可以点击 ctrl+o 来准备它^^

In my case I was not extending it from Fragment. Make sure you extend your fragment from Fragmentclass.
就我而言，我不是从 Fragment 扩展它。确保你从Fragment类中扩展你的片段。
public class fragment1 extends Fragment implements View.OnClickListener {
@Override
/// public View onCreateView.......
}
