Android 数字刷新从0开始变化的样式

在项目中用到的刷新数据的时候,从0开始刷新数据直到显示到最终的结果.

最终的效果图是这样子的,比较丑,就是个Demo,大家可以放在自己需要的界面上,

具体的实现代码如下:

package com.example.listviewtest;

import java.text.DecimalFormat;
import java.util.Timer;
import java.util.TimerTask;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends Activity {
    private TextView one;
    private TextView two;
    private TextView three;
    private TextView four;

    private Timer timer = null;
    private TimerTask mTimerTaskt;
    private int mIndext = 0;
    public static int MI = 50;

    private Double mRealValue1 = (Double) 1000.00, mRealValue2 = (Double) 50000.00,
            mRealValue3 = (Double) 44332.00, mRealValue4 = (Double)5654.00;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        one = (TextView) findViewById(R.id.one);
        two = (TextView) findViewById(R.id.two);
        three = (TextView) findViewById(R.id.three);
        four = (TextView) findViewById(R.id.four);
    }

    @Override
    protected void onResume() {
        super.onResume();
        timer = new Timer(true);
        setView();
    }

    public void refresh(View v){
        mIndext = 0;
        setView();
    }

    private void setView(){
        move();
    }

    private void move() {
        if (mIndext != 10) {
            if (timer != null) {
                if (mTimerTaskt != null)
                    mTimerTaskt.cancel(); // 将原任务从队列中移除
                mTimerTaskt = new MyTimerTaskT(); // 新建
                timer.schedule(mTimerTaskt, 10, MI);
            }
        }
    }

    private class MyTimerTaskT extends TimerTask {

        public void run() {

            int cont = 3;
            if (mIndext < 10) {
                mIndext++;
                cont = 3;
            } else {
                cont = 0;
            }
            handlert.sendMessageDelayed(
                    handlert.obtainMessage(cont, mIndext + ""), MI);
        }
    };
    /**
