Question

我有一个listview的片段。我正在使用包含textview和imagebutton的list项填充lisview。我想在fragment的onCreateView（）中的listitem按钮上设置onClickListener。我使用Cursoradapter和list_item.xml填充列表。但我无法在onCreateView（）中获得对此按钮的引用，因为按钮不是膨胀布局的一部分，而是list_item.xml的一部分。如何在listitem按钮上设置单击侦听器。非常感谢。这是我的片段：

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
       rootView = inflater.inflate(R.layout.activity_account, container, false);
 accountListView = (ListView)rootView. findViewById(R.id.list);
    mCursorAdapter = new accountCursorAdapter(getActivity(), null);
        accountListView.setAdapter(mCursorAdapter);

// I want to set click listener on button here.Button is in list_item.xml

//给我的cursoradapter充气。

   return rootView;
    }

我的适配器类： public class accountCursorAdapter扩展了CursorAdapter {

@SuppressWarnings("deprecation")

public accountCursorAdapter（Context context，Cursor c）{ super（context，c）;

}

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
    // Inflate a list item view using the layout specified in list_item.xml
    return LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);

}

@Override
public void bindView(View view, final Context context, Cursor cursor) {
    // Find individual views that we want to modify in the list item layout
    TextView nameTextView = (TextView) view.findViewById(R.id.name);

    ImageButton image = (ImageButton) view.findViewById(R.id.account_menu);

    int nameColumnIndex =  cursor.getColumnIndex(accountContract.accountEntry.COLUMN_NAME);

    String name = cursor.getString(nameColumnIndex);

    nameTextView.setText(name);

    int position;
    position=cursor.getPosition();
    image.setTag(position);
}

}

您可以在适配器中注册onClickListener：

  @Override
    public void bindView(View view, final Context context, Cursor cursor) {
        // Find individual views that we want to modify in the list item layout
        TextView nameTextView = (TextView) view.findViewById(R.id.name);

    ImageButton image = (ImageButton) view.findViewById(R.id.account_menu);

    int nameColumnIndex =  
    cursor.getColumnIndex(accountContract.accountEntry.COLUMN_NAME);

    String name = cursor.getString(nameColumnIndex);

    nameTextView.setText(name);

    int position;
    position=cursor.getPosition();
    image.setTag(position);

    image.setOnClickListener(new OnClickListener() {
    public void onClick(View v)
      {
        //do something
      } 
    });
}
