例如：A界面要收到B界面的更變信息

一、A界面注冊廣播

private static final String INTENT_BROADCAST = "android.intent.action.MEDICAL_BROADCAST";// 廣播跳轉意圖

?

LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(getActivity());
?????????? ?IntentFilter intentFilter = new IntentFilter();
????????????intentFilter.addAction(INTENT_BROADCAST);
?????????? ?BroadcastReceiver bordcastReceiver = new BroadcastReceiver() {

??????????????? ?@Override
??????????????? public void onReceive(Context context, Intent intent) {
??????????????????????//信息處理

??????????????????????Toast.makeText(context, "信息更新", Toast.LENGTH_SHORT).show();?????????????

??????????????? }
???????? ??};
??broadcastManager.registerReceiver(bordcastReceiver, intentFilter);

?

?

二、B界面發送廣播通知A界面改變信息

Intent broadcast = new Intent(INTENT_BROADCASTS);

LocalBroadcastManager.getInstance(this).sendBroadcast(broadcast);
