IntentService.java
public class Intentservice1 extends IntentService {
private String count;
private mybinder bind=new mybinder();
public class mybinder extends Binder
{
public String getcount()
{
System.out.println(count);
return count;
}
}
public Intentservice1()
{
super("Intentservice1");
System.out.println("构造方法");
}
@Override
public void onCreate()
{
super.onCreate();
System.out.println("onCreate方法");
}
@Override
public IBinder onBind(Intent intenr)
{
System.out.println("service isbind");
return bind;
}
@Override
protected void onHandleIntent(Intent arg0) {
// TODO Auto-generated method stub
}
}
MainActivity.java
private Intentservice1.mybinder binder1;
private ServiceConnection conn=new ServiceConnection()
{
@Override
public void onServiceConnected(ComponentName name,IBinder service)
{
System.out.println("service is connect");
binder1=(Intentservice1.mybinder)service;
System.out.println(binder1.getcount()); //这里发生了NullPointerException
}
在运行的时候发生NullPointerException，请问为什么binder1.getcount()会发生这样的错误？binder1不是已经获得返回的Intentservice1.mybinder的值了吗？这里应该如何去改？
