Installing

    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);
