noListener nolistener =new noListener();
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.demo);
Dialog alertDialog = new AlertDialog.Builder(this).setTitle("标题")
.setMessage("内容").setIcon(R.drawable.ic_launcher)
.setPositiveButton("确定", oklistener)
.setNegativeButton("取消", nolistener)
.create();
alertDialog.show();
}
public class okListener implements DialogInterface.OnClickListener{
@Override
public void onClick(DialogInterface dialog, int which) {
