public class MainActivity extends Activity {

private Button mybut=null;

private TextView mytxt=null;

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

this.mytxt=(TextView) super.findViewById(R.id.mytxt);

//获取我们的按钮对象

this.mybut=(Button) super.findViewById(R.id.mybut);

//为我们的按钮添加事件

this.mybut.setOnClickListener(new OnClickListenerImp());

}

public class OnClickListenerImp  implements OnClickListener{

public void onClick(View arg0) {

Dialog dialog=new AlertDialog.Builder(MainActivity.this)

.setTitle("删除对话框")

.setIcon(R.drawable.ic_launcher)

.setMessage("确认删除吗？")

//相当于点击确认按钮

.setPositiveButton("确认", new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog, int which) {

MainActivity.this.mytxt.setText("删除成功");

}

})

//相当于点击取消按钮

.setNegativeButton("取消", new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog, int which) {

// TODO Auto-generated method stub

MainActivity.this.mytxt.setText("取消删除");

}

})

.create();

dialog.show();

}

}

}
