IWAHalfModalPresenter

Simple modal presenter that can be easily customized

The modal will be shown in the bottom half part of the screen

This implementation is inspired by Georg Bednorz's animation

##Usage

First, add gradle dependency with command:

dependencies {

  compile 'com.inandwin.halfmodalpresenter:halfmodalpresenter:0.0.4' 
}

Inside your fragment/activity layout, just add 3 views (example below) :

An HalfModalView that will contain your button/expanding views
An HalfModalTriggerView that matches your trigger button
An HalfModalExpandedView that contain the content you want to show

HalfModalTriggerView and HalfModalExpandedView both inherits of LinearLayout, so you can adjust the orientation of this ViewGroups as you want to

<com.inandwin.halfmodalpresenter.HalfModalView

android:id="@+id/halfModal"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

app:backgroundButtonExpanded="@color/other"

app:backgroundButtonTrigger="@color/other">

<com.inandwin.halfmodalpresenter.HalfModalTriggerView

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:background="@color/other">

</com.inandwin.halfmodalpresenter.HalfModalTriggerView>

<com.inandwin.halfmodalpresenter.HalfModalExpandedView

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:background="@color/other">

</com.inandwin.halfmodalpresenter.HalfModalExpandedView>
  </com.inandwin.halfmodalpresenter.HalfModalView>

##Customization

The animation is splitted in two parts :

Trigger button becomes smaller and move a little bit to the top
Expanded view appears like an explosion

You can change these two backgrounds in layout:

app:backgroundButtonExpanded="@color/other" app:backgroundButtonTrigger="@color/other"

Or programmatically:

HalfModalView hfm = (HalfModalView) findViewById(R.id.halfModal);
 hfm.setBackgroundButtonTrigger(ContextCompat.getDrawable(this, R.color.other));
 hfm.setBackgroundButtonExpanded(ContextCompat.getDrawable(this, R.color.other));

If you need to show move the button to another part of the screen, you can adjust his position via :

app:positionFromTop="0.8"

hfm.setPositionFromTop(0.8f);
