Question

我用eclipse android写个textview显示一个txt的内容，代码没显示问题，虚拟机运行会停止，帮我看看。

package com.example.jishiben;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends Activity {

private EditText edit1;
private Button but1;
private TextView text1;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edit1=(EditText)findViewById(R.id.edit1);
but1=(Button)findViewById(R.id.but1);
text1=(TextView)findViewById(R.id.text1);
//读取txt文本，显示在textview上
StringBuffer sb=new StringBuffer();
BufferedReader br = null;
File file=new File("text1.txt");
try {
br = new BufferedReader(new FileReader(file));
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
String line="";
try {
while((line=br.readLine())!=null){
sb.append(line);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
br.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
text1.setText(sb.toString());
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

}
