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_modeor set it todisabled, this view will not draw any likes. - All attributes applicable to LikesLayout will be used as default values for child with
likes_modeset toenabled. - Custom drawable width and height will set exact size ignoring aspect ratio.
- Likes floating from bottom to top.
