BroadcastReceiver实现短信拦截

1、布局

<LinearLayout 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"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="启动" />

    <TextView
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

2、Service类

public class TestService extends Service {

	private Handler handler;
	
	private boolean flag = true;

	@Override
	public IBinder onBind(Intent arg0) {
		// 绑定到一个Activity中，这里一般不会编写内容，如果绑定了，则Activity关闭时，此Service也一起关闭。
		return null;
	}

	@Override
	public void onCreate() {
		super.onCreate();
		System.out.println("创建Service....");
		handler = new Handler() {
			@Override
			public void handleMessage(Message msg) {
				Toast.makeText(TestService.this, "启动了的服务....",
						Toast.LENGTH_SHORT).show();
			}
		};
	}

	@Override
	public void onDestroy() {
		super.onDestroy();
		System.out.println("销毁Service....");
		flag = false;
	}

	@Override
	public int onStartCommand(Intent intent, int flags, int startId) {
		// 启动服务时,自动调用这个方法
		Thread t = new Thread() {
			@Override
			public void run() {
				while (flag) {
					try {
						Thread.sleep(3000);
					} catch (Exception e) {
					}
					handler.sendEmptyMessage(0);
				}
			}
		};
		t.start();

		return super.onStartCommand(intent, flags, startId);
	}
}

3、BroadcastReceiver进行接收

public class MyReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		// 先判断是否是因为接收到短信进入此接收器的
		if (intent.getAction()
				.equals("android.provider.Telephony.SMS_RECEIVED")) {
			// 停止此广播,让后面的接收器无法接收到信息
			this.abortBroadcast();
			// 取得发送过来的参数
			Bundle b = intent.getExtras();
			if (b != null) {
				Object[] objs = (Object[]) b.get("pdus");

				SimpleDateFormat sf = new SimpleDateFormat(
						"yyyy-MM-dd HH:mm:ss");
				// 循环建立短信对象,并取得里面的信息.
				for (int i = 0; i < objs.length; i++) {
					SmsMessage msg = SmsMessage.createFromPdu((byte[]) objs[i]);
					// 取得消息中的内容
					String content = msg.getMessageBody();
					// 发送人信息
					String sender = msg.getDisplayOriginatingAddress();
					// 发送时间
					Date date = new Date(msg.getTimestampMillis());
					String sendTime = sf.format(date);

					// 打印结果
					System.out.println("接收到的消息为: " + sender + " --> " + content
							+ " --> " + sendTime);
				}
			}

		} else {
			Toast.makeText(context, "接收到了广播", Toast.LENGTH_SHORT).show();
		}
	}

}

4、Activity类

public class MainActivity extends Activity {

	private TextView text;

	private Button btn;

	@Override
	protected void onCreate(final Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		btn = (Button) findViewById(R.id.btn);
		text = (TextView) findViewById(R.id.content);
		btn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				// Intent in = new Intent(MainActivity.this, TestService.class);
				// startService(in);
				// Intent in = new Intent(MainActivity.this, MyReceiver.class);
				// sendBroadcast(in);

				String content = "测试消息内容";

				SmsManager manager = SmsManager.getDefault();

				List<String> all = manager.divideMessage(content);
				for (int i = 0; i < all.size(); i++) {
					manager.sendTextMessage("15162852231", null, all.get(0),
							null, null);
				}

			}
		});

		// 取得电话状态服务
		TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
		StringBuilder builder = new StringBuilder();
		builder.append(tm.getLine1Number() + "\r\n");
		builder.append(tm.getDeviceId() + "\r\n");
		builder.append(tm.getNetworkCountryIso() + "\r\n");
		builder.append(tm.getNetworkOperatorName() + "\r\n");

		// 取得网络状态
		ConnectivityManager cm = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);

		NetworkInfo info = cm.getActiveNetworkInfo();

		builder.append(info.getTypeName() + "\r\n");

		text.setText(builder.toString());

	}
}
