代码讲解

1. 重写BroadcastReceiver的onReceive方法

   let receiver = new JavaAdapter(android.content.BroadcastReceiver, {
         
         
     onReceive: function (context, intent) {
         
         
       log(intent);
       switch (intent.action) {
         
         
         case Intent.ACTION_BATTERY_CHANGED:
           log("ACTION_BATTERY_CHANGED");
           let level = intent.getIntExtra("level", 0);
           toastLog("当前电量:" + level + "%");
           break;
         case "android.intent.action.yashu":
           toastLog("牙叔自定义广播");
           let value = intent.getStringExtra("author");
           log("接收到数据 author: " + value);
           break;
       }
     },
   });
   

2. 注册广播

   context.registerReceiver(receiver, filter);
   

3. 发送广播

   app.sendBroadcast({
         
         
     action: action,
     extras: {
         
         
       author: "yashu",
     },
   });
   

4. 取消广播监听

   function unregisterReceiver() {
         
         
     if (flag) {
         
         
       receiver && context.unregisterReceiver(receiver);
       flag = false;
       toastLog("关闭广播");
     }
   }
