Android利用ContentProvider读取短信内容
本文实例为大家分享了Android利用ContentProvider读取短信内容的具体代码,供大家参考,具体内容如下
首先,我们来看下运行效果
运行效果如下:
展示短信内容的效果如下:
布局文件(activity_sms.xml)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_sms"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:orientation="vertical"
tools:context="com.example.administrator.myapplication.SMSActivity">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="获取手机所有的短信内容"
android:onClick="getContactsSms"
/>
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/lv_sms_list"
></ListView>
</LinearLayout>
一个简单的读取短信内容的例子(SMSActivity)
package com.example.administrator.myapplication;
import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class SMSActivity extends AppCompatActivity {
private ListView lv_sms_list;
private List<Map<String,Object>> data;
private SimpleAdapter simpleAdapter;
private ContentResolver contentResolver;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sms);
//获取访问者
contentResolver = getContentResolver();
lv_sms_list = (ListView) findViewById(R.id.lv_sms_list);
data = new ArrayList<Map<String,Object>>();
//适配器
simpleAdapter = new SimpleAdapter(this,data,android.R.layout.simple_list_item_2,new String[]{"names","note"},new int[]{android.R.id.text1,android.R.id.text2});
lv_sms_list.setAdapter(simpleAdapter);
}
public void getContactsSms(View view) {
//读取所有短信
Uri uri=Uri.parse("content://sms/");
ContentResolver resolver = getContentResolver();
Cursor cursor = resolver.query(uri, new String[]{"_id", "address", "body", "date", "type"}, null, null, null);
if(cursor!=null&&cursor.getCount()>0){
int _id;
String address;
String body;
String date;
int type;
while (cursor.moveToNext()){
Map<String,Object>map=new HashMap<String,Object>();
_id=cursor.getInt(0);
address=cursor.getString(1);
body=cursor.getString(2);
date=cursor.getString(3);
type=cursor.getInt(4);
map.put("names",body);
data.add(map);
Log.i("test","_id="+_id+" address="+address+" body="+body+" date="+date+" type="+type);
//通知适配器发生改变
simpleAdapter.notifyDataSetChanged();
}
}
}
}
最后需要在清单文件上配置读取短信的权限即可(AndroidManifest.xml)
<uses-permission android:name="android.permission.READ_SMS" />
