Usage
Add to your root build.gradle:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}Add the dependency:
dependencies {
compile 'com.github.huzenan:EasyPullLayout:v1.0.0'
}layout
Just wrap any layout with EasyPullLayout, then set the 'layout_type' attributes to 'content', 'edge_left', 'edge_top', 'edge_right' or 'edge_bottom':
<com.hzn.lib.EasyPullLayout
android:id="@+id/epl"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:max_offset_bottom="150dp"
app:max_offset_top="150dp"
app:trigger_offset_bottom="75dp"
app:trigger_offset_top="75dp">
<com.hzn.easypulllayout.recyclerview.TransformerView
android:id="@+id/topView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_type="edge_top" />
<com.hzn.easypulllayout.recyclerview.TransformerView
android:id="@+id/bottomView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_type="edge_bottom" />
<android.support.v7.widget.RecyclerView
android:id="@+id/rv"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_type="content" />
</com.hzn.lib.EasyPullLayout>Activity
Then set listeners:
  // set Pull Listener if you have to change the edge view while pulling
  epl.setOnPullListener { type, fraction, changed ->
when (type) {
EasyPullLayout.TYPE_EDGE_TOP -> {
topView.setFraction(START_FRACTION, fraction)
if (fraction == 1f)
topView.ready()
else
topView.idle()
}
...
}
  }
// set Trigger Listener, do your actions while the edge view is triggered
  epl.setOnTriggerListener {
when (it) {
EasyPullLayout.TYPE_EDGE_TOP -> {
topView.triggered()
}
EasyPullLayout.TYPE_EDGE_BOTTOM -> {
bottomView.triggered()
}
Loading()
}
  }Also if you want to check the edge yourself, set the Edge Listener(this will cover the default checking process):
epl.setOnEdgeListener {
...
if (onEdge)
return EasyPullLayout.TYPE_EDGE_TOP
...
}LayoutParams
