Likes Layout

LikesLayout is an implementation of layout that can draw likes similar to Periscope app.

Setup and usage

To include this library to your project add dependency in build.gradle file:

dependencies {
    compile 'com.github.iojjj:likeslayout:1.0.0'
}

There are three implementations of LikesLayout interface: LikesFrameLayout, LikesLinearLayout, LikesRelativeLayout. You can add them to your view via XML or in Java code.

<com.github.iojjj.likeslayout.LikesLinearLayout
        android:layout_width="match_parent"
        android:layout_height="250dp"
        app:likes_drawable="drawable resource id"
        app:likes_drawableWidth="custom drawable width"
        app:likes_drawableHeight="custom drawable height"
        app:likes_produceInterval="produce interval in milliseconds"
        app:likes_animationDuration="animationduration in milliseconds"
        app:likes_tintMode="off|on_successively|on_random"
        app:likes_tintColors="array resource id"
        app:likes_drawableAnimator="cannonical class name"
        app:likes_drawablePositionAnimator="cannonical class name"
        >

        <ImageButton
            ...
            app:likes_drawable="drawable resource id"
            app:likes_drawableWidth="custom drawable width"
            app:likes_drawableHeight="custom drawable height"
            app:likes_mode="enabled|disabled"
            app:likes_produceInterval="produce interval in milliseconds"
            app:likes_animationDuration="animationduration in milliseconds"
            app:likes_tintMode="off|on_successively|on_random"
            app:likes_tintColors="array resource id"
            app:likes_drawableAnimator="cannonical class name"
            app:likes_drawablePositionAnimator="cannonical class name"
            />

</com.github.iojjj.likeslayout.LikesLinearLayout>   

or

// create new LikesLayout
LikesLinearLayout likesLinearLayout = new LikesLinearLayout(getContext());
likesLinearLayout.setId(R.id.likes_layout);
// set layout height
final RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
        (int) (getResources().getDisplayMetrics().density * 250));
likesLinearLayout.setLayoutParams(params);
likesLinearLayout.setOrientation(LinearLayout.HORIZONTAL);
// make sure your buttons located at the bottom of LikesLayout
likesLinearLayout.setGravity(Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL);
likesLinearLayout.setPadding(0, 0, 0, (int) (getResources().getDisplayMetrics().density * 16));
// get attributes object that will store default values
likesLinearLayout.getAttributes().setAnimationDuration(1200);
likesLinearLayout.getAttributes().setTintMode(LikesAttributes.TINT_MODE_ON_SUCCESSIVELY);
likesLinearLayout.getAttributes().setTintColors(colors);

// it's time to add a button
ImageButton button = new ImageButton(getContext(), null, R.style.LikeButton_Grade);
button.setId(R.id.btn_grade);
button.setImageResource(R.drawable.ic_grade);
DrawableCompat.setTint(button.getDrawable(), ContextCompat.getColor(getContext(), R.color.colorAccent));
// you can create layout params for your button using LikesLayout.newLayoutParamsBuilder() method
// then using a builder you can set all necessary attributes values
final ViewGroup.LayoutParams params = likesLinearLayout
        .newLayoutParamsBuilder(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)
        .setDrawable(ContextCompat.getDrawable(getContext(), R.drawable.ic_grade_normal))
        .setAnimationDuration(3000)
        .setProduceInterval(500)
        .setPositionAnimatorFactory(new CustomPositionAnimatorFactory2())
        // don't forget to enable likes mode :)
        .setLikesMode(LikesAttributes.LIKES_MODE_ENABLED)
        .build();
// set parameters and add button to LikesLayout
button.setLayoutParams(params);
likesLinearLayout.addView(button);

There is the list of available attributes:

Attribute name ATLL CBOBC Description Default value
likes_animationDuration yes yes Animation duration in milliseconds. 1200
likes_drawable yes yes Drawable that will be drawn when user presses view. null
likes_drawableAnimator yes yes Drawable animator factory. @string/likes_drawable_animator_factory
likes_drawableHeight yes yes Custom drawable height. 0
likes_drawablePositionAnimator yes yes Drawable's position animator factory. @string/likes_position_animator_factory
likes_drawableWidth yes yes Custom drawable width. 0
likes_mode no yes Switch that allows to enable/disable drawing likes on touching child view. If likes_drawable is null, likes_mode will be considered as disabled. disabled
likes_produceInterval yes yes Rate at which new likes drawables are produced in milliseconds. 300
likes_tintMode yes yes Switch that allows to enable/disable tinting drawables. not_set
likes_tintColors yes yes Array of colors used for tinting drawables. If array is empty, likes_tintMode will be considered as off. null

Where:

  • ATLL - Available to LikesLayout
  • CBOBC - Can be overridden by child?

Produce likes programmatically

For this case you can use LikesLayout.produceLikes(...) methods, for example:

mLikesLayout.produceLikes(mBtnFavorite, 3, TimeUnit.SECONDS);

Make sure that child passed as an argument ( mBtnFavorite) was added to this mLikesLayout (via XML or Java code). Otherwise you will get IllegalArgumentException.

Custom Animations

You can provide your own animations. There are two types of animators available: DrawableAnimator and PositionAnimator. First one used for animating drawable itself (size, alpha, etc). Second one used for animating drawable's position. Note that PositionAnimator animates center of drawable. To use your custom animations you need to create DrawableAnimator.Factory or PositionAnimator.Factory implementations. Then you can set them via XML or in Java code.

Restrictions

  • If you will not set likes_mode or set it to disabled, this view will not draw any likes.
  • All attributes applicable to LikesLayout will be used as default values for child with likes_mode set to enabled.
  • Custom drawable width and height will set exact size ignoring aspect ratio.
  • Likes floating from bottom to top.
