BroadCastReceive的使用
1.在activity中Intent i = new Intent();i.setAction("ck"); //ck是随便定义的一个字符串i.putExtra("msg","message from broadcast...");sendBroadcast(i);2.在Manifest中<receiver android:name="MyReceiver"> //MyReceiver是接受类的名字<intent-filter><action android:name="ck"/> //和之前的字符串保持一致..</intent-filter></receiver>3.在接受类MyReceiver中MyReceiver继承BroadcastReceiver重写onReceive方法,获取msg信息..String msg = intent.getString("msg");
