1.发送标准广播 在一个Activity中,点击按钮,然后执行相应的代码:
public void click(View view) {
Intent intent =new Intent("com.example.my");
sendBroadcast(intent);
}2.发送有序广播
public void click(View view) {
Intent intent =new Intent("com.example.my");
sendOrderedBroadcast(intent,null);
}区别: 就是调用的函数不一样,参数不一样 sendOrderedBroadcast第二个参数是与权限有关
其实跟系统广播差不多,多了个LocalBroadcastManager 对象
public void click(View view) {
LocalBroadcastManager localBroadcastManager=LocalBroadcastManager.getInstance(this);
Intent intent=new Intent("com.my.localBroadCast");
localBroadcastManager.sendBroadcast(intent);
}
