Android查看手机通讯录（ListView）

一、添加权限：

<uses-permission android:name="android.permission.READ_CONTACTS" />

二、item.xml（创建ListView）：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <LinearLayout        android:layout_width="match_parent"        android:layout_height="60sp"        android:orientation="horizontal" >        <TextView            android:id="@+id/tv_name"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_vertical"            android:text="1111"            android:textSize="35sp" />        <TextView            android:id="@+id/tv_number"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="bottom"            android:text="2222"            android:textSize="25sp" />    LinearLayout>LinearLayout>

三、activity_main.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <ListView        android:id="@+id/lv"        android:layout_width="match_parent"        android:layout_height="match_parent" >    ListView>RelativeLayout>

四、ListViewAdapter.java(ListView的适配器):

package com.example.listviewshowlianxipeople;import java.util.List;import android.annotation.SuppressLint;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;@SuppressLint("InflateParams")public class ListViewAdapter extends BaseAdapter {    List names, phones;    LayoutInflater inflater;    @SuppressWarnings("static-access")    public ListViewAdapter(Context context, List names,            List phones) {        inflater = inflater.from(context);        this.names = names;        this.phones = phones;    }    @Override    public int getCount() {        return names.size();    }    @Override    public Object getItem(int position) {        return position;    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        View view;        if (convertView == null) {            view = inflater.inflate(R.layout.item, null);            TextView tv_name = (TextView) view.findViewById(R.id.tv_name);            TextView tv_phone = (TextView) view.findViewById(R.id.tv_number);            tv_name.setText(names.get(position));            tv_phone.setText(phones.get(position));        } else {            view = convertView;        }        return view;    }}

五、MainActivity.java:

package com.example.listviewshowlianxipeople;import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.database.Cursor;import android.os.Bundle;import android.provider.ContactsContract;import android.widget.ListView;public class MainActivity extends Activity {    ListView lv;    List list_phone, list_name;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        lv = (ListView) findViewById(R.id.lv);        list_name = new ArrayList();        list_phone = new ArrayList();        Cursor c = getContentResolver().query(                ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,                null, null);        //获取通讯录的信息        startManagingCursor(c);        int phoneIndex = 0, nameIndex = 0;        if (c.getCount() > 0) {            phoneIndex = c                    .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);            // 获取手机号码的列名            nameIndex = c                    .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);            // 获取用户名的列名        }        while (c.moveToNext()) {            String phone = c.getString(phoneIndex);            // 获取手机号码            list_phone.add(phone);            String name = c.getString(nameIndex);            // 获取用户名            list_name.add(name);        }        ListViewAdapter adapter = new ListViewAdapter(this, list_name,                list_phone);        lv.setAdapter(adapter);    }}
