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

MainActivity例如以下:

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;

	//全部短信

	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);

		//注冊内容观察者

		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例如以下:

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 {

	//全部短信

	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:

	 * 该处仅仅用依照时间降序取出第一条就可以

	 * 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例如以下:

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例如以下:

<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>
