一：想都不用想的，有图有真相，看着爽了，在看下面源码

二：实例源码分析

①：首先定义接口

package com.demo.tools.view;

/**

* 数字动画自定义

*

* @author zengtao 2015年7月17日 上午11:48:27

*

*/

public interface RiseNumberBase {

public void start();

public RiseNumberTextView withNumber(float number);

public RiseNumberTextView withNumber(float number, boolean flag);

public RiseNumberTextView withNumber(int number);

public RiseNumberTextView setDuration(long duration);

public void setOnEnd(RiseNumberTextView.EndListener callback);

}

②：自定义控件

package com.demo.tools.view;

import android.animation.ValueAnimator;

import android.content.Context;

import android.util.AttributeSet;

import android.widget.TextView;

import com.demo.tools.Utils;

/**

* 数字动画自定义

*

* @author zengtao 2015年7月17日 上午11:48:03

*

*/

public class RiseNumberTextView extends TextView implements RiseNumberBase {

private static final int STOPPED = 0;

private static final int RUNNING = 1;

private int mPlayingState = STOPPED;

private float number;

private float fromNumber;

private long duration = 1000;

/**

* 1.int 2.float

*/

private int numberType = 2;

private boolean flags = true;

private EndListener mEndListener = null;

final static int[] sizeTable = { 9, 99, 999, 9999, 99999, 999999, 9999999, 99999999, 999999999, Integer.MAX_VALUE };

public RiseNumberTextView(Context context) {

super(context);

}

public RiseNumberTextView(Context context, AttributeSet attr) {

super(context, attr);

}

public RiseNumberTextView(Context context, AttributeSet attr, int defStyle) {

super(context, attr, defStyle);

}

public interface EndListener {

public void onEndFinish();

}

public boolean isRunning() {

return (mPlayingState == RUNNING);

}

private void runFloat() {

ValueAnimator valueAnimator = ValueAnimator.ofFloat(fromNumber, number);

valueAnimator.setDuration(duration);

valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

@Override

public void onAnimationUpdate(ValueAnimator valueAnimator) {

if (flags) {

setText(Utils.format(",##0.00").format(Double.parseDouble(valueAnimator.getAnimatedValue().toString())) + "");

if (valueAnimator.getAnimatedValue().toString().equalsIgnoreCase(number + "")) {

setText(Utils.format(",##0.00").format(Double.parseDouble(number + "")));

}

} else {

setText(Utils.format("##0.00").format(Double.parseDouble(valueAnimator.getAnimatedValue().toString())) + "");

if (valueAnimator.getAnimatedValue().toString().equalsIgnoreCase(number + "")) {

setText(Utils.format("##0.00").format(Double.parseDouble(number + "")));

}

}

if (valueAnimator.getAnimatedFraction() >= 1) {

mPlayingState = STOPPED;

if (mEndListener != null)

mEndListener.onEndFinish();

}

}

});

valueAnimator.start();

}

private void runInt() {

ValueAnimator valueAnimator = ValueAnimator.ofInt((int) fromNumber, (int) number);

valueAnimator.setDuration(duration);

valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

@Override

public void onAnimationUpdate(ValueAnimator valueAnimator) {

setText(valueAnimator.getAnimatedValue().toString());

if (valueAnimator.getAnimatedFraction() >= 1) {

mPlayingState = STOPPED;

if (mEndListener != null)

mEndListener.onEndFinish();

}

}

});

valueAnimator.start();

}

static int sizeOfInt(int x) {

for (int i = 0;; i++)

if (x <= sizeTable[i])

return i + 1;

}

@Override

protected void onFinishInflate() {

super.onFinishInflate();

}

@Override

public void start() {

if (!isRunning()) {

mPlayingState = RUNNING;

if (numberType == 1)

runInt();

else

runFloat();

}

}

@Override

public RiseNumberTextView withNumber(float number, boolean flag) {

this.number = number;

this.flags = flag;

numberType = 2;

fromNumber = 0;

return this;

}

@Override

public RiseNumberTextView withNumber(float number) {

System.out.println(number);

this.number = number;

numberType = 2;

fromNumber = 0;

return this;

}

@Override

public RiseNumberTextView withNumber(int number) {

this.number = number;

numberType = 1;

fromNumber = 0;

return this;

}

@Override

public RiseNumberTextView setDuration(long duration) {

this.duration = duration;

return this;

}

@Override

public void setOnEnd(EndListener callback) {

mEndListener = callback;

}

}

③工具类的编写

package com.demo.tools;

import java.math.RoundingMode;

import java.text.DecimalFormat;

/**

* 配置文件

* @author zengtao 2015年7月17日 上午11:47:44

*

*/

public class Utils {

/**

* 格式化

*/

private static DecimalFormat dfs = null;

public static DecimalFormat format(String pattern) {

if (dfs == null) {

dfs = new DecimalFormat();

}

dfs.setRoundingMode(RoundingMode.FLOOR);

dfs.applyPattern(pattern);

return dfs;

}

}

三：主界面调用

package com.demo.ui;

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import com.demo.tools.view.RiseNumberTextView;

/**

* 数字动画

*

* @author zengtao 2015年7月17日 上午11:48:54

*

*/

public class MainActivity extends Activity {

private RiseNumberTextView number1, number2, number3, number4, number5;

private Button start;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main_activity);

initView();

}

private void initView() {

number1 = (RiseNumberTextView) findViewById(R.id.number1);

number2 = (RiseNumberTextView) findViewById(R.id.number2);

number3 = (RiseNumberTextView) findViewById(R.id.number3);

number4 = (RiseNumberTextView) findViewById(R.id.number4);

number5 = (RiseNumberTextView) findViewById(R.id.number5);

start = (Button) findViewById(R.id.start);

start.setOnClickListener(listener);

}

OnClickListener listener = new OnClickListener() {

@Override

public void onClick(View v) {

if (v == start) {

initData();

}

}

};

private void initData() {

number1.withNumber(12.3f).start();

number2.withNumber(16.3f).start();

number3.withNumber(10.3f).start();

number4.withNumber(18.3f).start();

number5.withNumber(17.3f).start();

}

}
