這裡我就簡單寫個動態註冊廣播的使用案例

• 傳送方（請求方）

傳送廣播

Intent intent = new Intent();
//設定廣播的名字（設定Action）
intent.setAction("voice_home");
sendBroadcast(intent);

• 接收方

註冊廣播

IntentFilter myIntentFilter = new IntentFilter();
myIntentFilter.addAction("voice_home");
//註冊廣播
registerReceiver(voiceReceiver, myIntentFilter);

廣播接收

private BroadcastReceiver voiceReceiver = new BroadcastReceiver() {
     @Override
     public void onReceive(Context context, Intent intent) {
         String action = intent.getAction();
         if (action.equals("voice_home")) {
             Intent intent1 = new                Intent(HostMainActivity.this,HostVoiceActivity.class);
             intent1.putExtra("voice_type","home");
             startActivity(intent1);
            }
        }
    };
