导入包：

import android.app.Activity;import android.app.AlertDialog;import android.content.DialogInterface;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;

MainActivity类实现：

public class MainActivity extends Activity {private Button btn1;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);btn1 = (Button) findViewById(R.id.button1);btn1.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setIcon(R.drawable.ic_launcher);builder.setTitle("你确定要离开吗？");builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubonShowDialog("你选择了确定");}});builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubonShowDialog("你选择了取消");}});builder.create().show();}private void onShowDialog(String str) {new AlertDialog.Builder(MainActivity.this).setMessage(str).show();}});}}
