android强制转换为整形,android – 类强制转换异常

这是我的代码：

package com.example.userpage;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

import android.widget.TextView;

public class UserPage extends Activity {

String tv,tv1;

EditText name,pass;

TextView x,y;

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Button button = (Button) findViewById(R.id.widget44);

button.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

name.setText(" ");

pass.setText(" ");

}

});

x = (TextView) findViewById(R.id.widget46);

y = (TextView) findViewById(R.id.widget47);

name = (EditText)findViewById(R.id.widget41);

pass = (EditText)findViewById(R.id.widget42);

Button button1 = (Button) findViewById(R.id.widget45);

button1.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

tv= name.getText().toString();

tv1 = pass.getText().toString();

x.setText(tv);

y.setText(tv1);

}

});

}

}
