【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);       }     @Overridepublic int getCount() {// TODO Auto-generated method stubreturn super.getCount();}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn super.getItem(position);}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn super.getItemId(position);}@SuppressWarnings("unused")@Overridepublic View getView(final int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubCompan 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);                   }@Overrideprotected void onListItemClick(ListView l, View v, int position, long id) {// TODO Auto-generated method stubSystem.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);}}
