Question

我的项目中有一个列表片段，当你从中选择一个项目时。它假设要更改片段，但它似乎根本没有接收到点击。我已经尝试设置后代的可聚焦性，但似乎没有任何东西可以让它甚至注册myclicks。我已经尝试过在这个网站上看过的解决方案，因为它似乎是一个常见的问题，但它们似乎都不允许我的特定程序正常工作

这是我的ListFragment：

import java.util.ArrayList;

import android.app.FragmentTransaction;
import android.app.ListFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class CharacterListFragment extends ListFragment{



    ArrayList<String> charList = new ArrayList<String>();





    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.character_list, null, false);
         ListView ls = (ListView) view.findViewById(android.R.id.list);
         ls.setClickable(false);
         return view;
        }
    @Override
    public void onListItemClick(ListView l, View v, int position, long id) {
         super.onListItemClick(l,v,position,id);
         String clickedDetail = (String) l.getItemAtPosition(position);

         CharacterFragment myCharFragment = new CharacterFragment();
         Bundle bundle = new Bundle();
         bundle.putString("KEY_DETAIL", clickedDetail);
         myCharFragment.setArguments(bundle);
         FragmentTransaction fragmentTransaction =
         getFragmentManager().beginTransaction();
         fragmentTransaction.replace(R.id.simpleFragment, myCharFragment);
         fragmentTransaction.commit(); 

     }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onActivityCreated(savedInstanceState);
        DatabaseHelper db = new DatabaseHelper(getActivity());
        db.open();
        charList = db.getArrayList();
        db.close();



        setListAdapter(new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, charList));
    }


}

我的片段布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:focusable="false" >
    <ListView android:id="@android:id/list"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:descendantFocusability="blocksDescendants"
    android:clickable="true"
    android:focusable="true">
    </ListView>
</LinearLayout>

我不知道它是否简单，我只是在俯视

Answer 1

  public static class FragmentA extends ListFragment {
    OnArticleSelectedListener mListener;
    ...
    @Override
    public void onListItemClick(ListView l, View v, int position, long id) {
        // Append the clicked item's row ID with the content provider Uri
        Uri noteUri = ContentUris.withAppendedId(ArticleColumns.CONTENT_URI, id);
        // Send the event and Uri to the host activity
        mListener.onArticleSelected(noteUri);
    }
    ...

这适用于listFragment

中的OnListItemClick

OnListItemClick无法在listfragment中工作
