我试图从我的活动中调用我的服务类的stopService()方法.但我不知道如何从我的活动类访问stopservice方法.我有下面的代码,但它不工作...........
这是HomeScreen类:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
enablecheck = (CheckBox)findViewById(R.id.enablecheck);
enablecheck.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(enablecheck.isChecked()){
startService(new Intent(HomeScreen.this, AutoService.class));
}else
{
stopService(new Intent(HomeScreen.this, AutoService.class));
}
}
});
}

事实上,要停止服务,我们必须使用该方法,stopService()并且您正在以正确的方式进行:
开始服务:
Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
startService(myService);

停止服务:
Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
stopService(myService);

如果你调用stopService(),那么调用onDestroy()服务中的stopService()方法(不是方法):
@Override
public void onDestroy() {
timer.cancel();
task.cancel();
Log.i(TAG, "onCreate() , service stopped...");
}

你必须实现这个onDestroy()方法!
这是一个完整的示例,包括如何启动/停止服务.

我实际上使用了与你相同的代码.我在清单中的服务注册如下
<service android:name=".service.MyService" android:enabled="true">
<intent-filter android:label="@string/menuItemStartService" >
<action android:name="it.unibz.bluedroid.bluetooth.service.MY_SERVICE"/>
</intent-filter>
</service>

在服务类中,我创建了一个相应的常量字符串,用于标识服务名称,如:
public class MyService extends ForeGroundService {
public static final String MY_SERVICE = "it.unibz.bluedroid.bluetooth.service.MY_SERVICE";
...
}

从相应的活动我称之为
startService(new Intent(MyService.MY_SERVICE));

并停止它
stopService(new Intent(MyService.MY_SERVICE));

它完美地运作.尝试检查您的配置,如果您没有发现任何异常,请尝试调试您的stopService是否正确调用.
取消选中该复选框后,它似乎应该停止服务。日志中是否有例外?stopService返回一个布尔值,指示它是否能够停止该服务。
如果要通过Intents启动服务,则可能要扩展IntentService而不是Service。当该类没有更多工作要做时,它将自行停止该服务。
