【android】checkedTextView形成自定义ListView

网络上的那个东西似乎都不准，以下是我做的此方法为可行。
首先，main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ListView>

</LinearLayout>

然后list.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
    <TextView
        android:id="@+id/_id"
        android:visibility="gone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:text="TextView" />
    
    <CheckedTextView
    android:id="@+id/checkText"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:gravity="center_vertical"
    android:checkMark="?android:attr/listChoiceIndicatorMultiple"
    android:paddingLeft="6dip"
    android:paddingRight="6dip"
/>

</RelativeLayout>

以下是自定义组件。

public final class Compan {
	public TextView id;
	public CheckedTextView ctv;
}

自定义adapter方法

package com.duduli.li;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.CheckedTextView;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;

public class MyAdapter extends SimpleCursorAdapter{
	 private List list = new ArrayList();
	 public String s[];
	 private List<Map<String, Object>> data;   
	 private LayoutInflater layoutInflater;   
	 private List<String> delNumber = new ArrayList<String>();
	 @SuppressWarnings("unused")
	 private Context context; 
	 public MyAdapter(Context context, int layout, Cursor c,
				String[] from, int[] to) {  
		 super(context, layout, c, from, to);
	        this.context = context;   
	        this.data = getData();   
	        this.layoutInflater = LayoutInflater.from(context);   
	    }  
	 
	 
	 @Override
		public int getCount() {
			// TODO Auto-generated method stub
			return super.getCount();
		}

		@Override
		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return super.getItem(position);
		}

		@Override
		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return super.getItemId(position);
		}

		
	@SuppressWarnings("unused")
	@Override
	public View getView(final int position, View convertView, ViewGroup parent) {
		// TODO Auto-generated method stub
		Compan cp = null;
		if(cp == null){
			cp = new Compan();
			convertView = layoutInflater.inflate(R.layout.list, null);
			cp.id = (TextView) convertView.findViewById(R.id._id);
			cp.ctv =  (CheckedTextView) convertView.findViewById(R.id.checkText);
			convertView.setTag(cp);
		}else{
			cp = (Compan) convertView.getTag();
		}
		cp.id.setText((CharSequence) data.get(position).get("_id"));
		cp.ctv.setText((CharSequence) data.get(position).get("Number"));
		
		
		
		return convertView;
	}
	



	public List<Map<String, Object>> getData() {
		List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

		while (getCursor().moveToNext()) {
			Map<String, Object> map = new HashMap<String, Object>();
			// System.out.println("ID: "+getCursor().getString(0));
			map.put("_id", getCursor().getString(0));
			// System.out.println("NAME: "+getCursor().getString(1));
			map.put("Number", getCursor().getString(1));
			list.add(map);
		}

		return list;
	}

}

下面是Acitivity

	

package com.duduli.li;

import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.CheckedTextView;
import android.widget.ListView;

import com.duduli.db.AllowCallDAO;

	/**
	 * This example shows how to use choice mode on a list. This list is 
	 * in CHOICE_MODE_MULTIPLE mode, which means the items behave like
	 * checkboxes.
	 */
	public class CallComingTest2Activity extends ListActivity {
		private CheckedTextView multiple;
	    @Override
	    public void onCreate(Bundle savedInstanceState) {
	        super.onCreate(savedInstanceState);
	        AllowCallDAO dao = new AllowCallDAO(this);
	        MyAdapter adapter = new MyAdapter(this, R.layout.list, dao.show()
	        		, new String[]{"_id","phonenr"}, new int[]{R.id._id,R.id.checkText});
	        
	        

	        
	        final ListView listView = getListView();
	        
	        listView.setItemsCanFocus(false);
	        setListAdapter(adapter);
	        
	       
	    }


		@Override
		protected void onListItemClick(ListView l, View v, int position, long id) {
			// TODO Auto-generated method stub
			System.out.println(position);

//			[b]下面的才是最重要的，网络上写的为：multiple = (CheckedTextView)l.getChildAt(position).findViewById(R.id.checkText);此方法很有问题，比如说listview进行翻页之后就会出问题。[/b]
			multiple = (CheckedTextView)v.findViewById(R.id.checkText);
			if(multiple != null){
				System.out.println("not null");
			}else{
				System.out.println("null");
			}
			
			if(multiple.isChecked()){
				multiple.setChecked(false);
			}else{
				multiple.setChecked(true);
			}
			super.onListItemClick(l, v, position, id);
		}
