Android短信监听(二)——利用ContentObserver实现短信监听

MainActivity如下:

package cc.testsmslistener;

import cc.testsmslistener.SMSContentObserver.MessageListener;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.widget.TextView;
import android.app.Activity;
/**

public class MainActivity extends Activity {
private TextView mTextView;
//所有短信
public static final String URI = "content://sms/";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
init();
}


private void init() {
mTextView=(TextView) findViewById(R.id.textView);

//注册内容观察者
SMSContentObserver smsContentObserver = 
    new SMSContentObserver(new Handler(),this);

this.getContentResolver().registerContentObserver
(Uri.parse(URI), true, smsContentObserver);

//回调
smsContentObserver.setOnReceivedMessageListener(new MessageListener() {
@Override
public void OnReceived(String message) {
mTextView.setText(message);
}
});
}

}

SMSContentObserver如下:

package cc.testsmslistener;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.database.ContentObserver;
import android.database.Cursor;
import android.net.Uri;
import android.os.Handler;
public class SMSContentObserver extends ContentObserver {
//所有短信
public static final String SMS_URI_ALL = "content://sms/";
//收件箱短信
public static final String SMS_URI_INBOX = "content://sms/inbox";
 //发件箱短信
public static final String SMS_URI_SEND = "content://sms/sent";
//草稿箱短信
public static final String SMS_URI_DRAFT = "content://sms/draft";
private Activity mActivity;
private List<SmsInfo> mSmsInfoList;
private MessageListener mMessageListener;

public SMSContentObserver(Handler handler, Activity activity) {
super(handler);
this.mActivity = activity;
}

@Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
Uri uri = Uri.parse(SMS_URI_INBOX);
mSmsInfoList = this.getSmsInfo(uri,mActivity);
mMessageListener.OnReceived(mSmsInfoList.get(0).getSmsbody());
System.out.println("Message content is:"+mSmsInfoList.get(0).getSmsbody());
System.out.println("Message info is:"+mSmsInfoList.get(0));
}

/**
 * 注意:
 * 该处只用按照时间降序取出第一条即可
 * 这条当然是最新收到的消息
 */
private List<SmsInfo> getSmsInfo(Uri uri,Activity activity){
List<SmsInfo> smsInfoList=new ArrayList<SmsInfo>();
String[] projection = new String[] { "_id", "address", "person","body", "date", "type" };
Cursor cusor = activity.managedQuery(uri, projection, null, null,"date desc limit 1");
int nameColumn = cusor.getColumnIndex("person");
int phoneNumberColumn = cusor.getColumnIndex("address");
int smsbodyColumn = cusor.getColumnIndex("body");
int dateColumn = cusor.getColumnIndex("date");
int typeColumn = cusor.getColumnIndex("type");
if (cusor != null) {
while (cusor.moveToNext()) {
SmsInfo smsinfo = new SmsInfo();
smsinfo.setName(cusor.getString(nameColumn));
smsinfo.setDate(cusor.getString(dateColumn));
smsinfo.setPhoneNumber(cusor.getString(phoneNumberColumn));
smsinfo.setSmsbody(cusor.getString(smsbodyColumn));
smsinfo.setType(cusor.getString(typeColumn));
smsInfoList.add(smsinfo);
}
cusor.close();
}
System.out.println("smsInfoList.size()="+smsInfoList.size());
return smsInfoList;
}



// 回调接口
public interface MessageListener {
public void OnReceived(String message);
}

public void setOnReceivedMessageListener(
MessageListener messageListener) {
this.mMessageListener=messageListener;
}
}

SmsInfo如下:

package cc.testsmslistener;
public class SmsInfo {
    //短信内容
private String smsbody;
//发送短信的电话号码
private String phoneNumber;
//发送短信时间
private String date;
//发送短信人的姓名
private String name;
//短信类型1是接收到的,2是已发出
private String type;

public String getSmsbody() {
return smsbody;
}

public void setSmsbody(String smsbody) {
this.smsbody = smsbody;
}

public String getPhoneNumber() {
return phoneNumber;
}

public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}

public String getDate() {
return date;
}

public void setDate(String date) {
this.date = date;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getType() {
return type;
}

public void setType(String type) {
this.type = type;
}

@Override
public String toString() {
return "SmsInfo [smsbody=" + smsbody + ", phoneNumber=" + phoneNumber
+ ", date=" + date + ", name=" + name + ", type=" + type + "]";
}


}

main.xml如下:

<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"
   >

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world"
        android:layout_centerInParent="true"
    />

</RelativeLayout>
