计算机113 袁博
创建一个名为layout_switch

package com.example.layout_switch;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.content.Intent;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

 

public class MainActivity extends Activity implements OnClickListener {

 

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

b1=(Button) findViewById(R.id.btn1);

b1.setOnClickListener(this);

}

Button b1;

 

@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;

}

 

@Override

public void onClick(View arg0) {

// TODO Auto-generated method stub

// Intent i=new Intent(MainActivity.this,MYActivity.class);

// startActivity(i);

Intent intent1=new Intent(MainActivity.this,MYActivity.class);

} 

}

代码实现效果如下:
