强制关闭onclick意图

Question

我已经尝试搜索并排查了几个小时，但我仍然无法弄清楚为什么我的应用程序会关闭。

当我点击文本时，它会完美地切换并显示figure603.xml，然后出现强制关闭。

任何人都可以告诉我出了什么问题？

figure603.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/figure"/>

</LinearLayout>

figure603.java

package com.rufflez.swipeytabs;

import android.app.Activity;
import android.os.Bundle;


public class figure603 extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.figure603);
    }

}

Fragment_6.java

import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import android.view.View.OnClickListener;

import com.actionbarsherlock.app.SherlockFragment;

public class Fragment_6 extends SherlockFragment{

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){

        View v =inflater.inflate(R.layout.fragment_6, container, false); // inflate the layout
        TextView tv = (TextView) v.findViewById(R.id.textView1); // initialize textview using inflated view object 

        tv.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            Intent intent=new Intent(getActivity(), figure603.class);
            startActivity(intent);
        }
        }); 
        return v;
}

}
