【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

"1.0" encoding="utf-8"?>
""
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >


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

然后list.xml

"1.0" encoding="utf-8"?>
""
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

android:id="@+id/_id"
android:visibility="gone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="TextView" />


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"
/>

以下是自定义组件。

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

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> data;
private LayoutInflater layoutInflater;
private List delNumber = new ArrayList();
@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> getData() {
List> list = new ArrayList>();

while (getCursor().moveToNext()) {
Map map = new HashMap();
// 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;
}

}

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> data; private LayoutInflater layoutInflater; private List delNumber = new ArrayList(); @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> getData() { List> list = new ArrayList>(); while (getCursor().moveToNext()) { Map map = new HashMap(); // 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);
}






}
