先编写activity_main.xml文件

代码如下:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/MyLayout"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
	<TextView 
	    android:id="@+id/mytext"
	    android:text="北京魔乐科技软件学院"
	    android:layout_width="wrap_content"
	    android:layout_height="wrap_content"/>
	<Button 
	    android:id="@+id/mybut"
	    android:text="删除"
	    android:layout_width="wrap_content"
	    android:layout_height="wrap_content"/>
</LinearLayout>

  然后编写MainActivity类中的代码;

代码如下:

package com.example.myporject;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.DialogInterface;
import android.text.method.HideReturnsTransformationMethod;
import android.text.method.PasswordTransformationMethod;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnFocusChangeListener;
import android.view.View.OnLongClickListener;
import android.view.ViewGroup;
import android.view.WindowManager;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.DatePicker;
import android.widget.DatePicker.OnDateChangedListener;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.SeekBar;
import android.widget.SimpleAdapter;
import android.widget.Spinner;
import android.widget.TextView;
import android.widget.TimePicker;
import android.widget.TimePicker.OnTimeChangedListener;

public class MainActivity extends Activity {
	private Button mybut = null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        this.mybut = (Button)super.findViewById(R.id.mybut);
        this.mybut.setOnClickListener(new OnClickListenerlmpl());
    }
    private class OnClickListenerlmpl implements OnClickListener{
    	public void onClick(View v){
    		Dialog dialog =new AlertDialog.Builder(MainActivity.this).setIcon(R.drawable.logo).setTitle("确定删除").setMessage("您确定要删除该条信息吗")
    				.setPositiveButton("删除",new DialogInterface.OnClickListener() {
						
						public void onClick(DialogInterface dialog, int which) {
							// TODO Auto-generated method stub
							
						}
					} ).setNeutralButton("查看详情", new DialogInterface.OnClickListener() {
						
						public void onClick(DialogInterface dialog, int which) {
							// TODO Auto-generated method stub
							
						}
					}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
						
						public void onClick(DialogInterface dialog, int which) {
							// TODO Auto-generated method stub
							
						}
					}).create();
    		dialog.show();
    	}

		
    }
}

  效果图如下:
