广播的使用

第一个页面

1.注册广播 onCreat里面

/* 注册一个广播，用来刷新内容 */

LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(activity);

IntentFilter intentFilter = new IntentFilter();

intentFilter.addAction("android.intent.action.CART_BROADCAST2");

broadcastManager.registerReceiver(mItemViewListClickReceiver, intentFilter);

2.接受广播

/** 用于接收刷新数据 */

BroadcastReceiver mItemViewListClickReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

ContactsDetails mContactsDetails = (ContactsDetails) intent.getSerializableExtra("contact");

if (mContactsDetails == null) { // 从创建页面过来的 需要刷新数据

exeContactsSelectListAsyncTask(false, "onReceive");

} else { // 从联系人详情页面过来的不需要刷数据

for (int i = 0; i < mContactsList.size(); i++) {

if (mContactsList.get(i).contacts_id.equals(mContactsDetails.contacts_id)) {

ContactsDetails contactsDetails = mContactsList.get(i);

mContactsList.set(i, mContactsDetails);

mPeopleAdapter.notifyDataSetChanged(mContactsList);

}

}

}

}

};

第二个页面

3.发送广播

Intent intent = new Intent("android.intent.action.CART_BROADCAST2");

intent.putExtra("people_str", mContactsSelectListResponse.result_json.contacts_count);

LocalBroadcastManager.getInstance(getActivity()).sendBroadcast(intent);
