enter code here if (createSuccses){
                        val userDataChange=Intent(BRODCAST_USER_DATA_CHANGE)
                        LocalBroadcastManager.getInstance(this).sendBroadcast(
                            userDataChange
                        )
                        enableSpinner(false)
                        finish()

如何将全局广播更改为局部广播

1)创建实例

LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);

2)用于注册BroadcastReceiver

取代

registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

与

localBroadcastManager.registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

3)用于发送广播信息

取代

sendBroadcast(intent);

与

localBroadcastManager.sendBroadcast(intent);

4)注销广播信息

取代

unregisterReceiver(mybroadcast);

与

localBroadcastManager.unregisterReceiver(mybroadcast);

enter code here if (createSuccses){
                        val userDataChange=Intent(BRODCAST_USER_DATA_CHANGE)
                        LocalBroadcastManager.getInstance(this).sendBroadcast(
                            userDataChange
                        )
                        enableSpinner(false)
                        finish()

在Eclipse中，最终我不得不通过右键单击我的项目并选择添加兼容性/支持库:

Android工具->添加支持库

一旦添加了它，我就可以在代码中使用LocalBroadcastManager类了。

一个实现LocalBroadcastManager的Activity和Service的例子可以在开发者文档中找到。我个人觉得它非常有用。

我更愿意全面地回答。

LocalbroadcastManager included in android 3.0 and above so you have to use support library v4 for early releases. see instructions here Create a broadcast receiver: private BroadcastReceiver onNotice= new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { // intent can contain anydata Log.d("sohail","onReceive called"); tv.setText("Broadcast received !"); } }; Register your receiver in onResume of activity like: protected void onResume() { super.onResume(); IntentFilter iff= new IntentFilter(MyIntentService.ACTION); LocalBroadcastManager.getInstance(this).registerReceiver(onNotice, iff); } //MyIntentService.ACTION is just a public static string defined in MyIntentService. unRegister receiver in onPause: protected void onPause() { super.onPause(); LocalBroadcastManager.getInstance(this).unregisterReceiver(onNotice); } Now whenever a localbroadcast is sent from applications' activity or service, onReceive of onNotice will be called :).
