4.监听手机收到短信

先是广播接收器

class InnerSmsReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {L.d("sms");//获取短信内容返回的是一个Object数组Object[] objs = (Object[]) intent.getExtras().get("pdus");//遍历数组得到短信内容for (Object obj : objs) {// 超过140字节,会分多条短信发送//把数组元素转换成短信对象SmsMessage sms = SmsMessage.createFromPdu((byte[]) obj);originatingAddress = sms.getOriginatingAddress();messageBody = sms.getMessageBody();L.i("短信号码:" + originatingAddress + ";短信内容:"+ messageBody);//弹框显示showSmsWindow(originatingAddress, messageBody);}}
}

下面注册广播

// 拦截短信, 同等条件下,动态注册更优先获取广播
mReceiver = new InnerSmsReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
filter.setPriority(Integer.MAX_VALUE);
registerReceiver(mReceiver, filter);
自定义广播里有一个监听到短信后弹出一个窗口，下面代码：
private void showSmsWindow(String title, String content) {//窗口管理器wm = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE);//布局参数layoutParams = new WindowManager.LayoutParams();layoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;layoutParams.height = WindowManager.LayoutParams.MATCH_PARENT;layoutParams.flags =//WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE | 不能触摸WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH;//WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | 沒有焦点//格式layoutParams.format = PixelFormat.TRANSLUCENT;//类型layoutParams.type = WindowManager.LayoutParams.TYPE_PHONE;mView = (SessionLinearLayout) View.inflate(getApplicationContext(), R.layout.window_item, null);tv_title = (TextView) mView.findViewById(R.id.tv_title);tv_title.setText("发件人：" + originatingAddress);tv_content = (TextView) mView.findViewById(R.id.tv_content);tv_content.setText("短信内容：" + messageBody);btnSend = (Button) mView.findViewById(R.id.btnSend);btnSend.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {if (mView.getParent() != null) {wm.removeView(mView);}//send smsUri uri = Uri.parse("smsto:" + originatingAddress);Intent i = new Intent(Intent.ACTION_SENDTO, uri);i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);i.putExtra("sms_baby", "");startActivity(i);}});wm.addView(mView, layoutParams);//监听返回键mView.setDispatchKeyEventListener(mDispatchKeyEventListener);
}

上面代码里面还有一个按键的监听，Android里面的Home，Back，Menu三个键同样使用广播进行管理。

HomeWatcherReceiver mHomeKeyReceiver;
//注册Home监听广播
mHomeKeyReceiver = new HomeWatcherReceiver();
final IntentFilter homeFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
registerReceiver(mHomeKeyReceiver, homeFilter);
//监听返回键
mView.setDispatchKeyEventListener(mDispatchKeyEventListener);
/*** 返回鍵监听*/
private SessionLinearLayout.DispatchKeyEventListener mDispatchKeyEventListener = new SessionLinearLayout.DispatchKeyEventListener() {@Overridepublic boolean dispatchKeyEvent(KeyEvent event) {if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) {if (mView.getParent() != null) {wm.removeView(mView);}return true;}return false;}
};
还有一个Home键
/*** 监听Home键*/
class HomeWatcherReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);if (SYSTEM_DIALOG_REASON_HOME_KEY.equals(reason)) {if (mView.getParent() != null) {wm.removeView(mView);}}}}
}

后面的代码看了下，的确是基础课程，都比较简单，没什么复杂的东西，好多都是用了很多次的东西，下一篇再把零碎知识整理一下，也就完工了。哈哈  ^_^
