Android自定义ListFragment 显示

1.继承ListFragment类, 实现方法getView方法

package com.lance.sample;import java.util.ArrayList;import android.content.Intent;import android.os.Bundle;import android.support.v4.app.ListFragment;import android.view.View;import android.view.ViewGroup;import android.widget.ArrayAdapter;import android.widget.CheckBox;import android.widget.ListView;import android.widget.TextView;public class UserListFragment extends ListFragment {@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);ArrayList<User> mUsers = UserDB.get().getUsers();UserAdapter adapter = new UserAdapter(mUsers);setListAdapter(adapter);}/** * Listener List item click event */public void onListItemClick(ListView l, View v, int position, long id) {User user = (User)getListAdapter().getItem(position);Intent intent = new Intent(getActivity(), UserDetailActivity.class);intent.putExtra(UserDetailFragment.USER_ID, user.getId());startActivity(intent);}/** * rewrite getView method * @author lance */private class UserAdapter extends ArrayAdapter<User>{public UserAdapter(ArrayList<User> mUsers) {super(getActivity(), 0, mUsers);}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {if(convertView == null) {convertView = getActivity().getLayoutInflater().inflate(R.layout.activity_list_item, null);}User user = getItem(position);CheckBox vipBox = (CheckBox)convertView.findViewById(R.id.list_item_vip);vipBox.setChecked(user.isVip());TextView nameText = (TextView)convertView.findViewById(R.id.list_item_name);nameText.setText(user.getName());TextView cardNoText = (TextView)convertView.findViewById(R.id.list_item_cardno);cardNoText.setText(String.valueOf(user.getCardNo()));return convertView;}}}

2.定义显示view文件activity_list_item.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"     android:paddingTop="4dp">    <CheckBox        android:id="@+id/list_item_vip"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentRight="true"        android:padding="6dp"        android:layout_marginTop="4dp"        android:text="@string/list_item_vip"         android:focusable="false"/>    <TextView        android:id="@+id/list_item_name"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:paddingLeft="4dp"        android:paddingRight="4dp"        android:textStyle="bold"        android:layout_toLeftOf="@id/list_item_vip"        android:text="@string/list_item_name" />    <TextView        android:id="@+id/list_item_cardno"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentLeft="true"        android:layout_below="@id/list_item_name"        android:layout_toLeftOf="@id/list_item_vip"        android:padding="4dp"        android:text="@string/list_item_name" /></RelativeLayout>

3.fragment托管给activity

package com.lance.sample;import android.os.Bundle;import android.support.v4.app.Fragment;import android.support.v4.app.FragmentActivity;import android.support.v4.app.FragmentManager;/** * 提供基本FragmentActivity, 供list列表和detail用 * @author lance */public abstract class BaseFragmentActivity extends FragmentActivity {/** * create fragment * @return */protected abstract Fragment createFrag();@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);FragmentManager fm = getSupportFragmentManager();Fragment fragment = fm.findFragmentById(R.id.frag_container);if(fragment == null) {fragment = createFrag();fm.beginTransaction().add(R.id.frag_container, fragment).commit();}}}
