我正在尝试调用postannonce
方法,但它没有显示在Onclick
方法列表中。这是我的SecondeFrament.java
代码:

import java.io.File;
public class SecondeFragment extends Fragment {
public static final String TAG = "seconde";
ProgressBar prog;
Button post;
EditText titre;
EditText text;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.secondefragment, container, false);
post = (Button) view.findViewById(R.id.ressayer);
titre = (EditText) view.findViewById(R.id.titreannonce);
text = (EditText) view.findViewById(R.id.textannonce);
prog = (ProgressBar) view.findViewById(R.id.progressBar2);
return view;
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
public void postannonce(View view){
prog.setVisibility(View.VISIBLE);
String titreannonce = titre.getText().toString();
String textannonce= text.getText().toString();
if((!titreannonce.trim().equals(""))&&(!textannonce.trim().equals(""))){
new PostActivity(getActivity(),prog).execute(titreannonce, textannonce);
}
else{
Toast.makeText(getActivity(), "Veuillez remplir tout les champs svp", Toast.LENGTH_SHORT).show();
prog.setVisibility(View.INVISIBLE);
}
}
}

我还是Android新手,如果有人能告诉我代码中缺少什么,我将不胜感激。

您的postannonce
方法需要在SecondeFragment
课程内。改变这一部分:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
public void postannonce(View view){
prog.setVisibility(View.VISIBLE);
String titreannonce = titre.getText().toString();
String textannonce= text.getText().toString();
if((!titreannonce.trim().equals(""))&&(!textannonce.trim().equals(""))){
new PostActivity(getActivity(),prog).execute(titreannonce, textannonce);
}
else{
Toast.makeText(getActivity(), "Veuillez remplir tout les champs svp", Toast.LENGTH_SHORT).show();
prog.setVisibility(View.INVISIBLE);
}
}
}
看起来像这样:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
public void postannonce(View view){
prog.setVisibility(View.VISIBLE);
String titreannonce = titre.getText().toString();
String textannonce= text.getText().toString();
if((!titreannonce.trim().equals(""))&&(!textannonce.trim().equals(""))){
new PostActivity(getActivity(),prog).execute(titreannonce, textannonce);
}
else{
Toast.makeText(getActivity(), "Veuillez remplir tout les champs svp", Toast.LENGTH_SHORT).show();
prog.setVisibility(View.INVISIBLE);
}
}
}
}
