Answer 1

类似于这样的 IntentFilter commandFilter = new IntentFilter();
commandFilter.addAction(SERVICECMD);
commandFilter.addAction(TOGGLEPAUSE_ACTION);
commandFilter.addAction(PAUSE_ACTION);
commandFilter.addAction(NEXT_ACTION);
commandFilter.addAction(PREVIOUS_ACTION);
commandFilter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
registerReceiver(mIntentReceiver, commandFilter);
private BroadcastReceiver mIntentReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
String cmd = intent.getStringExtra("command");
MusicUtils.debugLog("mIntentReceiver.onReceive " + action + " / "
+ cmd);
if (CMDNEXT.equals(cmd) || NEXT_ACTION.equals(action)) {
} else if (CMDPREVIOUS.equals(cmd)
|| PREVIOUS_ACTION.equals(action)) {
} else if (CMDTOGGLEPAUSE.equals(cmd)
|| TOGGLEPAUSE_ACTION.equals(action)) {
} else if (CMDPAUSE.equals(cmd) || PAUSE_ACTION.equals(action)) {
} else if (CMDSTOP.equals(cmd)) {
} else if (MediaAppWidgetProvider.CMDAPPWIDGETUPDATE.equals(cmd)) {
}else if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals(intent
.getAction())) {
}
}
};
