安卓广播使用 BroadcastReceiver

1    private String ALLDATA_NAME = "action.allData";

IntentFilter myIntentFilter = new IntentFilter();
        myIntentFilter.addAction(ALLDATA_NAME);
        // 注册广播
        mActivity.registerReceiver(mBroadcastReceiver, myIntentFilter);

/**

     * 广播接收类
     */
    private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (action.equals(ALLDATA_NAME)) {
                onRefresh();
            }
        }

    };
