android listView实现单选

1，先上布局文件，利用了以前的布局，不要在意变量名称的细节

layout_wifi_item.xml

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

<CheckBox
android:id="@+id/tv_wifiName"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="@drawable/item_click"
android:button="@null"
android:gravity="center"
android:text="123"
android:textColor="@android:color/black" />
</LinearLayout>

2 drawable文件

item_click.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/colorAccent" android:state_selected="true" />
<item android:drawable="@color/colorAccent" android:state_checked="true" />
<item android:drawable="@color/white" />
</selector>

3.adapter   

AbstractAdapter 这是adapter的父类，里面主要重写了BaseAdapter，不用在意

package com.my.test.mytestdemo.adapter;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CheckBox;
import com.my.test.mytestdemo.R;
import java.util.List;
import java.util.Map;

/**

public class ItemClickAdapter extends AbstractAdapter {
private Map<Integer, Boolean> map;

public ItemClickAdapter(Context context, List listData, Map<Integer, Boolean> map) {
super(context, listData);
this.map = map;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
convertView = inflate(R.layout.layout_wifi_item);
holder = new ViewHolder();
holder.tv_wifiName = (CheckBox) convertView.findViewById(R.id.tv_wifiName);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
if (map.get(position)){
holder.tv_wifiName.setChecked(true);
}else {
holder.tv_wifiName.setChecked(false);
}
holder.tv_wifiName.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (holder.tv_wifiName.isChecked()) {
for (Integer keys : map.keySet()) {
if (map.get(keys)) {
map.put(keys, false);
}
}
map.put(position, true);
} else {
map.put(position, false);
}
notifyDataSetChanged();
}
});
return convertView;
}

private class ViewHolder {
private CheckBox tv_wifiName;
}
}

4.activity 

package com.my.test.mytestdemo.listview.listview;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ListView;
import com.my.test.mytestdemo.R;
import com.my.test.mytestdemo.adapter.ItemClickAdapter;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class ItemClickActivity extends AppCompatActivity {
private ListView lv_list;
private ItemClickAdapter adapter;
private List<String> list = new ArrayList<String>();
private Map<Integer,Boolean> map=new HashMap<Integer, Boolean>();

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_item_click);
initView();
}

private void initView() {
for (int i = 0; i < 5; i++) {
list.add(i + "");
map.put(i,false);
}
lv_list = (ListView) findViewById(R.id.lv_list);
adapter = new ItemClickAdapter(this, list,map);
lv_list.setAdapter(adapter);
lv_list.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}
}

6,代码挺简单，就不做说明
