HoldingButton

Button which is visible while user holds it. Main use case is controlling audio recording state (like in Telegram, Viber, VK).

Getting started

Add library as dependency to your build.gradle.

compile 'com.dewarder:holdingbutton:0.1.3'

How to use

1. Wrap your layout with HoldingButtonLayout. It is simple FrameLayout inside.

    <com.dewarder.holdinglibrary.HoldingButtonLayout
        android:id="@+id/input_holder"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        
        ...
     
        <ImageView
            android:id="@+id/start_record"
            android:layout_width="48dp"
            android:layout_height="match_parent"
            android:scaleType="center"
            android:src="@drawable/ic_mic_black_24dp"/>
   
        ...
   
    </com.dewarder.holdinglibrary.HoldingButtonLayout>
   
   

2. Set app:hbl_holding_view property to id of view which would be translated to HoldingButton

    <com.dewarder.holdinglibrary.HoldingButtonLayout
        android:id="@+id/input_holder"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:hbl_holding_view="@+id/start_record">
   

3. Set app:hbl_icon property to icon (usually it is the same as in translated view) which would be appeared in HoldingButton.

    <com.dewarder.holdinglibrary.HoldingButtonLayout
        android:id="@+id/input_holder"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:hbl_holding_view="@+id/start_record"
        app:hbl_icon="@drawable/ic_mic_black_24dp">
   

4. Listen events

   mHoldingButtonLayout.addListener(new SimpleHoldingButtonLayoutListener() {
       @Override
       public void onOffsetChanged(float offset, boolean isCancel) {
           mSlideToCancel.setTranslationX(-mHoldingButtonLayout.getWidth() * offset);
           mSlideToCancel.setAlpha(1 - SLIDE_TO_CANCEL_ALPHA_MULTIPLIER * offset);
       }
   });
   
   

5. Enjoy!
