broadcastReceiver传值的⽤法详情
注意：⼴播的发送都是全局发送的，跨应⽤的，所以我们在使⽤的时候不能使⽤下⾯的action传参数，需要添加参数
intent.setComponent(new ComponentName("com.archermind.fm", "com.archermind.fm.MusicWidgetBroadcastReceiver"));
第⼀步：⾃定义⼴播
安卓intent用法
public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = Extras();
int count = Int( "count" );
Log.v("MainActivity", "Count is " + count);}}
第⼆步：声明和注册⼴播
private MyReceiver receiver = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
setContentView( R.layout.activity_main );
//启动服务
startService(new Intent(MainActivity.this, MyService.class));
//注册⼴播接收器
receiver=new MyReceiver();
IntentFilter filter=new IntentFilter();
filter.addAction("li.demobroad.MyService");
isterReceiver(receiver,filter);
}
@Override
protected void onDestroy() {
//结束服务
stopService(new Intent(MainActivity.this, MyService.class));
}
第三步：补充服务端
public class MyService extends Service {
private int count = 0;
private boolean tag=false;
@Override
public void onCreate() {
new Thread(new Runnable() {
@Override
public void run() {
while (!tag) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
count++;
Log.v("MyService", "Count is " + count);
//发送⼴播
Intent intent=new Intent();
intent.putExtra("count", count);
intent.setAction("li.demobroad.MyService"); sendBroadcast(intent);}}
}).start();
}
@Override
public IBinder onBind(Intent intent) {return null;}
@Override
public void onDestroy() {
count=0;
tag = true;
Log.v("MyService", "on destroy");
}}
第三步：清单⽂件中注册服务（注意资源回收 ⼴播和服务）<service
android:name=".MyService"
android:enabled="true"
android:exported="true"
tools:ignore="WrongManifestParent"></service>
