Usage
-----
Using the ExpandableTextView is very easy, it's just a regular TextView with some extra functionality added to it. By defining the android:maxLines attribute, you can set the default number of lines for the TextView collapsed state.
```xml
```
In your Activity or Fragment:
```java
final ExpandableTextView expandableTextView = (ExpandableTextView) this.findViewById(R.id.expandableTextView);
final Button buttonToggle = (Button) this.findViewById(R.id.button_toggle);
// set animation duration via code, but preferable in your layout files by using the animation_duration attribute
expandableTextView.setAnimationDuration(750L);
// set interpolators for both expanding and collapsing animations
expandableTextView.setInterpolator(new OvershootInterpolator());
// or set them separately
expandableTextView.setExpandInterpolator(new OvershootInterpolator());
expandableTextView.setCollapseInterpolator(new OvershootInterpolator());
// toggle the ExpandableTextView
buttonToggle.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(final View v)
{
buttonToggle.setText(expandableTextView.isExpanded() ? R.string.expand : R.string.collapse);
expandableTextView.toggle();
}
});
// but, you can also do the checks yourself
buttonToggle.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(final View v)
{
if (expandableTextView.isExpanded())
{
expandableTextView.collapse();
buttonToggle.setText(R.string.expand);
}
else
{
expandableTextView.expand();
buttonToggle.setText(R.string.collapse);
}
}
});
// listen for expand / collapse events
expandableTextView.setOnExpandListener(new ExpandableTextView.OnExpandListener()
{
@Override
public void onExpand(final ExpandableTextView view)
{
Log.d(TAG, "ExpandableTextView expanded");
}
@Override
public void onCollapse(final ExpandableTextView view)
{
Log.d(TAG, "ExpandableTextView collapsed");
}
});
```
