bindservice同步问题

[kingecg]

请看代码：

package com.ewinfo.test;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.os.RemoteException;
import android.widget.Button;
import android.widget.TextView;
import android.view.View;

public class Main extends Activity implements View.OnClickListener {
	private iTService mService;
	private ServiceConnection mConnection = new ServiceConnection() {

		@Override
		public void onServiceConnected(ComponentName name, IBinder service)
		{
			// TODO Auto-generated method stub
			mService=iTService.Stub.asInterface(service);
		}

		@Override
		public void onServiceDisconnected(ComponentName name)
		{
			// TODO Auto-generated method stub
			
		}
		
	};
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView txt=(TextView)findViewById(R.id.hello);
        this.bindService(new Intent(iTService.class.getName()), mConnection, Context.BIND_AUTO_CREATE);//---1
        if(this.mService!=null)
        {
        	try
			{
				if(this.mService.isStart())
					txt.setText("Service is Start");
				else
					txt.setText("Service not Start");
			} catch (RemoteException e)
			{
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
        }
        Button start=(Button)findViewById(R.id.start_service);
        start.setOnClickListener(this);
    }
	@Override
	public void onClick(View v)
	{
		// TODO Auto-generated method stub
		this.startService(new Intent(this,TService.class));
	}
}

问题：如何在1处bind成功后让mService立即可用（即this.mService!=null成立）？

友情帮顶~~~

onServiceConnected 方法不就是bind成功立马调用的吗？

[nj_dobetter]

貌似只有在
public void onServiceConnected(ComponentName name, IBinder service)
{
// TODO Auto-generated method stub
mService=iTService.Stub.asInterface(service);
}
中做后续工作了

顶三楼，还有就是可以在事件响应中用mservice

[kuangbenderen]

应该是在Start之后，Service才可以使用吧

[biaozai06]

在onCreate()函数里面不一定已经bind service成功，但是bind service成功后系统会立即回调onServiceConnected()方法，因此对service的处理要等到nServiceConnected()之后

6楼正解。高焕堂老师形容得好：Don't call me, I'll call you back。

我也做过类似的测试。可能是进程同步的问题？你在onServiceConnected调用之后再操作mService就行了。

你可以设置第二个事件响应，这个时候mService就不为空了
