Android的选项卡布局子活动出错？

Question

我为我的应用程序创建了tab小部件。每个活动都有多个子活动。我的主要活动是

package com.example.travelmate;

import android.app.ActivityGroup;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class TaxiActivity extends ActivityGroup 
{

Button taxi_meter_btn1,taxi_meter_btn2;


public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);


    setContentView(R.layout.taxi_layout);


    taxi_meter_btn1 = (Button)findViewById(R.id.meter_bt1);
    taxi_meter_btn2 = (Button)findViewById(R.id.meter_bt2);


    taxi_meter_btn1.setOnClickListener(new View.OnClickListener()
    {

        @Override
        public void onClick(View v1)
        {
            // TODO Auto-generated method stub



            Intent activity3Intent = new Intent(v1.getContext(),TaxiMeterActivityMain.class);
            replaceContentView1("activity3", activity3Intent);


        }
    });

    taxi_meter_btn2.setOnClickListener(new View.OnClickListener()
    {

        @Override
        public void onClick(View v2)
        {
            // TODO Auto-generated method stub



            Intent activity4Intent = new Intent(v2.getContext(),TaxiMeterActivityMain.class);
            replaceContentView2("activity3", activity4Intent);


        }
    });





}
@SuppressWarnings("deprecation")
public void replaceContentView1(String id, Intent newIntent) {
    View view = getLocalActivityManager().startActivity(id,
            newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
            .getDecorView();
    this.setContentView(view);
}
public void replaceContentView2(String id, Intent newIntent) {
    @SuppressWarnings("deprecation")
    View view = getLocalActivityManager().startActivity(id,
            newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
            .getDecorView();
    this.setContentView(view);
}
}

我的子活动是

 public class TaxiMeterActivityMain extends ActivityGroup
 {

Button end_jour_btn;


public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);


    setContentView(R.layout.taxi_meter_layout);



    end_jour_btn = (Button)findViewById(R.id.end_jour_bt);



    end_jour_btn.setOnClickListener(new View.OnClickListener()
    {

        @Override
        public void onClick(View v) 
        {

            // TODO Auto-generated method stub


            Intent activity3Intent = new Intent(TaxiMeterActivityMain.this, TaxiActivity.class);
            replaceContentView("activity3", activity3Intent);
        }
    });


}
@SuppressWarnings("deprecation")
public void replaceContentView(String id, Intent newIntent) {
    View view = getLocalActivityManager().startActivity(id,
            newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
            .getDecorView();
    this.setContentView(view);
}
 }

我想将这个子活动称为两个不同的按钮两次。当我点击第一个按钮时，我可以回到主要活动。但是当点击相同活动的第二个按钮时，它会引发错误，如http://pastie.org/8420928。我怎么能解决这个问题，有人可以帮助我吗？提前谢谢。
