Android Text Animations

Android Text Animations -Best Libraries and Examples

So you are developing your app and you have the space for alittle modernization. How about animating some of your text? Well this is what this tutorial is dedicated for. We want to see how to animate texts in android.

(a). TextSurface

A little animation framework which could help you to show message in a nice looking way.

Here’s an example:

Android Text Animation

Step 1: Install TextSurface

First add jitpack as a maven url in your allProjects closure in the project-level build.gradle file:

 maven { url "https://jitpack.io" }

Then specify the dependency in the build.gradle file:

implementation 'com.github.elevenetc:textsurface:0.9.1'

Step 2: Add to Layout

The next step is to add TextSurface to your XML layout:

<su.levenetc.android.textsurface.TextSurface
        android:id="@+id/text_surface"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

Step 3: Write Code

  • Create TextSurface instance or add it in your layout.
  • Create Text instancies with TextBuilder defining appearance of text and position:
Text textDaai = TextBuilder
        .create("Daai")
        .setSize(64)
        .setAlpha(0)
        .setColor(Color.WHITE)
        .setPosition(Align.SURFACE_CENTER).build();

Create animations and pass them to the TextSurface instance:

textSurface.play(
        new Sequential(
                Slide.showFrom(Side.TOP, textDaai, 500),
                Delay.duration(500),
                Alpha.hide(textDaai, 1500)
        )
);

Adjusting animations

  • To play animations sequentially use Sequential.java

  • To play animations simultaneously use Parallel.java

  • Animations/effects could be combined like this:

    new Parallel(Alpha.show(textA, 500), ChangeColor.to(textA, 500, Color.RED))

    i.e. alpha and color of text will be changed simultaneously in 500ms

Adding your own animations/effects

There’re two basic classes which you could extend to add custom animation:

Proguard configuration

The framework is based on standard android animation classes which uses reflection extensively. To avoid obfuscation you need to exclude classes of the framework:

-keep class su.levenetc.android.textsurface.** { *; }

Example

Text Scaling Example

Here is an example that scales text:

public class ScaleTextSample {
    public static void run(TextSurface textSurface) {
//      Text textA = TextBuilder.create("oat cake")
////                .setScale(2.0f, Pivot.RIGHT)
//              .build();
//
//      textSurface.play(TYPE.SEQUENTIAL,
//              //Just.show(textA)
//              new Scale(textA, 1000, 0.1f, 1.5f, Pivot.RIGHT)
//      );

        Text textA = TextBuilder.create("textA")
//              .setPosition(Align.SURFACE_CENTER)
                .build();

        Text textB = TextBuilder.create("textB")
                .setPosition(Align.LEFT_OF, textA)
                .build();

        Text textC = TextBuilder.create("textC")
                .setPosition(Align.RIGHT_OF, textA)
                .build();

        Text textD = TextBuilder.create("textD")
                .setPosition(Align.LEFT_OF, textB)
                .build();

        Text textE = TextBuilder.create("textE")
                .setPosition(Align.RIGHT_OF, textC)
                .build();

        textSurface.play(TYPE.PARALLEL,
                Just.show(textA, textB),
                new Sequential(new Scale(textA, 1000, 1, 2, Pivot.CENTER), new Scale(textA, 1000, 2, 1, Pivot.CENTER))
//              new Parallel(new Scale(textA, 500, 1.5f, 1f, Pivot.LEFT), new Scale(textA, 500, 1, 1.5f, Pivot.LEFT)),
//              new Sequential(Delay.duration(250), new Parallel(new Scale(textB, 500, 1.5f, 1f, Pivot.LEFT), new Scale(textB, 500, 1, 1.5f, Pivot.LEFT))),
//              new Sequential(Delay.duration(500), new Parallel(new Scale(textC, 500, 1.5f, 1f, Pivot.LEFT), new Scale(textC, 500, 1, 1.5f, Pivot.LEFT))),
//              new Sequential(Delay.duration(750), new Parallel(new Scale(textD, 500, 1.5f, 1f, Pivot.LEFT), new Scale(textD, 500, 1, 1.5f, Pivot.LEFT)))
        );
    }
}

SurfaceScale example

Here is a surface scale example:

public class SurfaceScaleSample {
    public static void play(TextSurface textSurface) {

        Text textA = TextBuilder.create("How are you?").setPosition(Align.SURFACE_CENTER).build();
        Text textB = TextBuilder.create("Would you mind?").setPosition(Align.BOTTOM_OF | Align.CENTER_OF, textA).build();
        Text textC = TextBuilder.create("Yes!").setPosition(Align.BOTTOM_OF | Align.CENTER_OF, textB).build();

        textSurface.play(TYPE.SEQUENTIAL,
                Alpha.show(textA, 500),
                new AnimationsSet(TYPE.PARALLEL,
                        new AnimationsSet(TYPE.PARALLEL, Alpha.show(textB, 500), Alpha.hide(textA, 500)),
                        new ScaleSurface(500, textB, Fit.WIDTH)
                ),
                Delay.duration(1000),
                new AnimationsSet(TYPE.PARALLEL,
                        new AnimationsSet(TYPE.PARALLEL, Alpha.show(textC, 500), Alpha.hide(textB, 500)),
                        new ScaleSurface(500, textC, Fit.WIDTH)
                )
        );
    }
}

3D Rotation Example

Here is an example of 3D text rotation:

public class Rotation3DSample {
    public static void play(TextSurface textSurface) {
        Text textA = TextBuilder.create("How are you?").setPosition(Align.SURFACE_CENTER).build();
        Text textB = TextBuilder.create("I'm fine! And you?").setPosition(Align.SURFACE_CENTER, textA).build();
        Text textC = TextBuilder.create("Haaay!").setPosition(Align.SURFACE_CENTER, textB).build();
        int duration = 2750;

        textSurface.play(TYPE.SEQUENTIAL,
                new AnimationsSet(TYPE.SEQUENTIAL,
                        Rotate3D.showFromCenter(textA, duration, Direction.CLOCK, Axis.X),
                        Rotate3D.hideFromCenter(textA, duration, Direction.CLOCK, Axis.Y)
                ),
                new AnimationsSet(TYPE.SEQUENTIAL,
                        Rotate3D.showFromSide(textB, duration, Pivot.LEFT),
                        Rotate3D.hideFromSide(textB, duration, Pivot.RIGHT)
                ),
                new AnimationsSet(TYPE.SEQUENTIAL,
                        Rotate3D.showFromSide(textC, duration, Pivot.TOP),
                        Rotate3D.hideFromSide(textC, duration, Pivot.BOTTOM)
                )
        );
    }
}

(b). Ticker

An Android text view with scrolling text change animation.

Android Text Ticker

Ticker is a simple Android UI component for displaying scrolling text. Think about how an odometer scrolls when going from one number to the next, that is similar to what Ticker does. The Ticker handles smooth animations between strings and also string resizing (e.g. animate from "9999" to "10000").

You can specify how the animations proceed by defining an array of characters in order. Each character displayed by Ticker is controlled by this array which dictates how to animate from a starting character to a target character. For example, if you just use a basic ASCII character list, when animating from ‘A’ to ‘Z’, it will go from ‘A’ -> ‘B’ -> … ‘Z’. We will perform wrap-around animation when it’s faster (e.g. ‘Z’ to ‘A’ will just animate ‘Z’ -> ‘A’).

Here’s how to use it.

Step 1: Install it

Install it using the following implementation statement:

implementation 'com.robinhood.ticker:ticker:2.0.2'

Step 2: Add to Layout

After installation you need to add it to your xml layout as follows:

<com.robinhood.ticker.TickerView
    android:id="@+id/tickerView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

Step 3: Use it in Code

Then in your java or kotlin code you use like below:

final TickerView tickerView = findViewById(R.id.tickerView);
tickerView.setCharacterLists(TickerUtils.provideNumberList());

How to Customize

It has basic customization attributes for example:

android:gravity="center"
android:textColor="@color/colorPrimary"
android:textSize="16sp"
app:ticker_animationDuration="1500"
app:ticker_preferredScrollingDirection="any"

Or tocustomize it programmatically:

tickerView.setTextColor(textColor);
tickerView.setTextSize(textSize);
tickerView.setTypeface(myCustomTypeface);
tickerView.setAnimationDuration(500);
tickerView.setAnimationInterpolator(new OvershootInterpolator());
tickerView.setGravity(Gravity.START);
tickerView.setPreferredScrollingDirection(TickerView.ScrollingDirection.ANY);

(c). CountAnimationTextView

A tiny Android library makes very easier count animation of TextView.

Here is the demo:

Counter TextView

Let’s proceed and see how to use this CounterAnimationTextView

Step 1: Install it

Install it using the following implementation statement:

implementation 'com.daasuu:CountAnimationTextView:0.1.2'

Step 2: Add to Layout

The next step after installation is to add it to your XML layout:

    <com.daasuu.cat.CountAnimationTextView
        android:id="@+id/count_animation_textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="0"
        />

Step 3: Write Code

The first step is to reference the widget from the layout:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mCountAnimationTextView = (CountAnimationTextView) findViewById(R.id.count_animation_textView);
    }

Now you can animate with duration as follows:

    mCountAnimationTextView
        .setAnimationDuration(5000)
        .countAnimation(0, 99999);

Or with a decimal format as follows:

    mCountAnimationTextView
        .setDecimalFormat(new DecimalFormat("###,###,###"))
        .setAnimationDuration(10000)
        .countAnimation(0, 9999999);

To animate with an interpolator:

    mCountAnimationTextView
        .setInterpolator(new AccelerateInterpolator())
        .countAnimation(0, 9999999);

Example

Here is a full example. Start by installing the library as has been discussed.

activity_main.xml

Now design the main activity layout as follows;

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.daasuu.countanimationtextview.MainActivity">

    <Button
        android:id="@+id/btn_count_anim_0"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="count up 0 to 99999"
        android:textAllCaps="false" />

    <Button
        android:id="@+id/btn_count_anim_1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="count down 99999 to 0"
        android:textAllCaps="false" />

    <Button
        android:id="@+id/btn_count_anim_2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="count up 0 to 9999999 with \nDemicalFormat of '###,###,###'"
        android:textAllCaps="false" />

    <com.daasuu.cat.CountAnimationTextView
        android:id="@+id/count_animation_textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="0"
        android:textSize="32sp" />
</LinearLayout>

MainActivity.java

Now come and write your java code as follows:

import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;

import com.daasuu.cat.CountAnimationTextView;

import java.text.DecimalFormat;

public class MainActivity extends AppCompatActivity {

    private CountAnimationTextView mCountAnimationTextView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mCountAnimationTextView = (CountAnimationTextView) findViewById(R.id.count_animation_textView);

        Button button0 = (Button) findViewById(R.id.btn_count_anim_0);
        button0.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mCountAnimationTextView
                        .setAnimationDuration(5000)
                        .countAnimation(0, 99999);
            }
        });

        Button button1 = (Button) findViewById(R.id.btn_count_anim_1);
        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mCountAnimationTextView
                        .setAnimationDuration(5000)
                        .countAnimation(99999, 0);
            }
        });

        Button button2 = (Button) findViewById(R.id.btn_count_anim_2);
        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mCountAnimationTextView
                        .setDecimalFormat(new DecimalFormat("###,###,###"))
                        .setAnimationDuration(10000)
                        .countAnimation(0, 9999999);
            }
        });

        mCountAnimationTextView.setCountAnimationListener(new CountAnimationTextView.CountAnimationListener() {
            @Override
            public void onAnimationStart(Object animatedValue) {
                // do nothing
            }

            @Override
            public void onAnimationEnd(Object animatedValue) {
                mCountAnimationTextView.clearDecimalFormat();
            }
        });

    }
}
