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 {
	@Override
	public 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);
		}
		
		@Override
		public 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();
	
	@Override
	protected 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();
		}
	}
}
