repositories {
// ...
maven { url 'https://jitpack.io' }
}
dependencies {
implementation 'com.github.bffcorreia:fole:1.0.0'
}
Basic Usage
Fole.with(yourTextView).text("Your text...").maxLines(4).toggleView(yourToggleView);
Fole.with(yourTextView).text("Your text...").maxChars(50).toggleView(yourToggleView);
Ellipsis Placeholder
Fole.with(yourTextView).maxLines(4).ellipsisPlaceholder("###").toggleView(yourToggleView);
Callback
If you want to know when the TextView expands or collapses just add a FoleCallback.
FoleCallback callback = new FoleCallback() {
@Override public void onTextExpand() {
// Handle onTextExpand!
}
@Override public void onTextCollapse() {
// Handle onTextCollapse!
}
};
Fole.with(yourTextView).maxLines(4).toggleView(yourToggleView, callback);
Animations
To animate the TextView when it extends or collapses, simply add your animation.
Animation animation = AnimationUtils.loadAnimation(context, android.R.anim.fade_in);
Fole.with(yourTextView)
.maxLines(4)
.animation(animation)
.toggleView(yourToggleView);
If you want to use different animations:
Animation expandAnimation = AnimationUtils.loadAnimation(context, android.R.anim.fade_in);
Animation collapseAnimation = AnimationUtils.loadAnimation(context, android.R.anim.slide_in_left);
Fole.with(yourTextView)
.maxLines(4)
.expandAnimation(expandAnimation)
.collapseAnimation(collapseAnimation)
.toggleView(yourToggleView);
