android 中点击一个Button,怎的在TextView中显示点击次数

//这是GridView的OnItemClickListener的监听public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {   LayoutInflater inflater = LayoutInflater.from(this);   //自定义了布局               final View v = inflater.inflate(R.layout.view02, null);       Button Right = (Button) v.findViewById(R.id.right);    Right.setOnClickListener(new righonclickListener());    AlertDialog.Builder builder = new AlertDialog.Builder(this)    .setTitle("请选择：")    .setView(v)    .setIcon(arg0.getId())    .setPositiveButton("确定", new DialogInterface.OnClickListener(){    @Override    public void onClick(DialogInterface dialog, int which) {           TextView num_tv = (TextView) v.findViewById(R.id.morensl);    num_tv.setText(String.valueOf(m_ClickNum));    String numStr = num_tv.getText().toString();                //省略下边对numStr的操作                        }        })    .setNegativeButton("取消", null);    AlertDialog alert = builder.create();    alert.show();            }//对Button的监听器    public class righonclickListener implements OnClickListener{    @Override    public void onClick(View arg0) {    // TODO Auto-generated method stub     m_ClickNum ++ ;//已经声明为Private                     }            }
