Android BroadcastReceiver传值 _Broadcast

壮心未与年俱老，死去犹能作鬼雄。这篇文章主要讲述Android BroadcastReceiver传值相关的知识，希望能为你提供帮助。
1、定义两个常量：广播名和广播键值

public static finalString ACTION_BONED = "ACTION_BONED"; public static final String ACTION_BONED_DATA = "https://www.songbingjia.com/android/ACTION_BONED_DATA";

2、在Activity或Service中发送广播

Intent mIntent = new Intent(BluetoothBonedReceiver.ACTION_BONED); mIntent.putExtra(BluetoothBonedReceiver.ACTION_BONED_DATA, sb.toString()); sendBroadcast(mIntent);

3、定义广播接收器

private BroadcastReceiver bonedReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if(BluetoothBonedReceiver.ACTION_BONED.equals(action)){ String data = https://www.songbingjia.com/android/intent.getStringExtra(BluetoothBonedReceiver.ACTION_BONED_DATA); Message msg = new Message(); msg.obj = data; handler.sendMessage(msg); } } };

4、注册广播

IntentFilter intentFilter = new IntentFilter(); // 监视蓝牙关闭和打开的状态 intentFilter1.addAction(BluetoothBonedReceiver.ACTION_BONED); registerReceiver(bonedReceiver, intentFilter);

5、注销广播
