Android Imitation Alipay balance treasure in the digital animation effect _android

To implement the effect diagram:

Here is the specific code that can be copied directly:

Package com.lcw.rabbit.widget;
Import Android.animation.ObjectAnimator;
Import Android.content.Context;
Import Android.text.TextUtils;
Import Android.util.AttributeSet;
Import Android.view.animation.AccelerateDecelerateInterpolator;

Import Android.widget.TextView;  /** * High imitation balance treasure Digital Animation * Create By:chenwei.li * date:2016-07-20 * time:11:52 * email:lichenwei.me@foxmail.com/Public
 Class Countnumberview extends TextView {//animation time long private int duration = 1500;
 Display digital private float number;

 Displays an expression private String regex; Displays the expression public static final string Intregex = "%1$01.0f";//No decimal, Integer public static final String Floatregex = "%1$01.2f";
 /Keep 2 decimal countnumberview (context, AttributeSet attrs) {Super (context, attrs); /** * Displays the animated number * @param numbers * @param regex */public void shownumberwithanimation (float, String rege
 x) {if (Textutils.isempty (regex)) {//default is integer This.regex = Intregex;
 else {This.regex = regex; }//Modify the Number property to call theSetnumber method Objectanimator Objectanimator = Objectanimator.offloat (This, "number", 0, number);
 Objectanimator.setduration (duration);
 Accelerator, from slow to fast to slow objectanimator.setinterpolator (new Acceleratedecelerateinterpolator ());
 Objectanimator.start ();
 /** * Get current digit * @return/public float GetNumber () {return number;
 /** * According to regular expression, display corresponding digital style * @param number/public void Setnumber (float number) {this.number = #;
 SetText (String.Format (regex, number)); }
}

Using the method, which is declared in XML (which can be used entirely as TextView), is invoked directly in the Java file:

 Mtvcountnum1.shownumberwithanimation (3201.23f, Countnumberview.floatregex);
 Mtvcountnum2.shownumberwithanimation (65535f, Countnumberview.intregex);

Here for flexible use, set aside the digital display format (the default to provide a full model and floating-point type), you can change according to their own needs Regex .

The first format parameter for String.Format, which references the description of the following API:

The syntax for format specifiers for general types, character types, and numeric types is as follows:

%[argument_index$][flags][width][.precision]conversion

Optionally argument_index , a decimal integer indicating the position of the parameter in the parameter list. The first parameter is referenced by "1$", the second parameter is referenced by "2$", and so on.

Optional flags is the character set that modifies the output format. The set of valid flags depends on the type of conversion.

Optionally width , a nonnegative decimal integer indicating the minimum number of characters to write to the output.

Optional precision is a nonnegative decimal integer that is typically used to limit the number of characters. Specific behavior depends on the type of conversion.
