RotatingText

Rotating text is an Android library that can be used to make text switching painless and beautiful, with the use of interpolators, typefaces and more customisations.

Usage

Just add the following dependency in your app's build.gradle

dependencies {
      compile 'com.sdsmdg.harjot:rotatingtext:1.0.2'
}

Example Usage 1 (Simple)

XML

<com.sdsmdg.harjot.rotatingtext.RotatingTextWrapper
        android:id="@+id/custom_switcher"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

Java

RotatingTextWrapper rotatingTextWrapper = (RotatingTextWrapper) findViewById(R.id.custom_switcher);
rotatingTextWrapper.setSize(35);

Rotatable rotatable = new Rotatable(Color.parseColor("#FFA036"), 1000, "Word", "Word01", "Word02");
rotatable.setSize(35);
rotatable.setAnimationDuration(500);

rotatingTextWrapper.setContent("This is ?", rotatable);

Result

Example Usage 2 (Typeface + Interpolator)

XML

<com.sdsmdg.harjot.rotatingtext.RotatingTextWrapper
        android:id="@+id/custom_switcher"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

Java

Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/Raleway-Light.ttf");
Typeface typeface2 = Typeface.createFromAsset(getAssets(), "fonts/Reckoner_Bold.ttf");

RotatingTextWrapper rotatingTextWrapper = (RotatingTextWrapper) findViewById(R.id.custom_switcher);
rotatingTextWrapper.setSize(35);
rotatingTextWrapper.setTypeface(typeface2);

Rotatable rotatable = new Rotatable(Color.parseColor("#FFA036"), 1000, "Word", "Word01", "Word02");
rotatable.setSize(35);
rotatable.setAnimationDuration(500);
rotatable.setTypeface(typeface);
rotatable.setInterpolator(new BounceInterpolator());

rotatingTextWrapper.setContent("This is ?", rotatable);

Result

Example Usage 3 (Multiple Rotatables)

XML

<com.sdsmdg.harjot.rotatingtext.RotatingTextWrapper
        android:id="@+id/custom_switcher"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

Java

Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/Raleway-Light.ttf");
Typeface typeface2 = Typeface.createFromAsset(getAssets(), "fonts/Reckoner_Bold.ttf");

RotatingTextWrapper rotatingTextWrapper = (RotatingTextWrapper) findViewById(R.id.custom_switcher);
rotatingTextWrapper.setSize(35);
rotatingTextWrapper.setTypeface(typeface2);

Rotatable rotatable = new Rotatable(Color.parseColor("#FFA036"), 1000, "Word", "Word01", "Word02");
rotatable.setSize(35);
rotatable.setTypeface(typeface);
rotatable.setInterpolator(new AccelerateInterpolator());
rotatable.setAnimationDuration(500);

Rotatable rotatable2 = new Rotatable(Color.parseColor("#123456"), 1000, "Word03", "Word04", "Word05");
rotatable2.setSize(25);
rotatable2.setTypeface(typeface);
rotatable2.setInterpolator(new DecelerateInterpolator());
rotatable2.setAnimationDuration(500);

rotatingTextWrapper.setContent("This is ? and ?", rotatable, rotatable2);

Result

Documentation

Rotating text is made of two parts : RotatingTextWrapper and Rotatable.
Each rotatable encapsulates the collection of words that are two be periodically switched and also defines various properties related to these words, like, size, color, animation interpolator etc.
Each Rotatable must be a part of a RotatingTextWrapper. This defines the actual layout of the text and the positions of the rotating text.

For eg : rotatingTextWrapper.setContent("This is ?", rotatble);. Here the ? denotes the postion of the rotatable.

RotatingTextWrapper

Property	Function	Description
Content	setContent(...)	Set the actual content. Composed of a String and array of Rotatables.
Typeface	setTypeface(...)	Set the typeface of the non-rotating text
Size	setSize(...)	Set the size of the non-rotating text
Pause	pause(x)	Method to pause the 'x'th rotatable
Resume	resume(x)	Method to resume the 'x'th rotatable

Rotatable

Property	Function	Description
Color	setColor(...)	Set the color of the rotating text associated with this rotatable
Size	setSize(...)	Set the size of the rotating text associated with this rotatable
Typeface	setTypeface(...)	Set the typeface of the rotating text associated with this rotatable
Interpolator	setInterpolator(...)	Set the animation interpolator used while switching text
Update Duration	setUpdateDuration(...)	Set the interval between switching the words
Animation Duration	setAnimationDuration(...)	Set the duration of the switching animation
Center Align	setCenter(...)	Align the rotating text to center of the textview if set to true
