HoldToLoadLayout is a view group that can contain a single child. It draws your child to middle of layout, and performs loading wheel around it with settings you determined.

Simply, add a child to HoldToLoadLayout, than set properties about the animation you'd like.

     <com.melih.holdtoload.HoldToLoadLayout
            android:id="@+id/holdToLoadLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
    
            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/github"/>
        </com.melih.holdtoload.HoldToLoadLayout>

         HoldToLoadLayout holdToLoadLayout = (HoldToLoadLayout) findViewById(R.id.holdToLoadLayout);
         
         holdToLoadLayout.setStrokeWidth(10); // Set stroke width in px ( dp in xml )
         holdToLoadLayout.setStrokeAlpha(255); // Set alpha value of paint ( 0 - 255 )
         holdToLoadLayout.setPlayReverseAnimation(true); // Reverse like it fills, with animation
         holdToLoadLayout.setStopWhenFilled(false); // Stop when holded fully
         holdToLoadLayout.setColorAnimator(Color.YELLOW, Color.RED); // Animate color while drawing
         holdToLoadLayout.setStartAngle(Angle.TOP); // Use any of the pre-defined starting angle
         holdToLoadLayout.setStartAngle(30); // Starting angle of loading

Customization

setStrokeWidth(int strokeWidth)

• Sets stroke width in pixels if strokeWidth is greater than 0.
  You can set dp values from XML. Default is 0.
  Does NOT updates stroke width dynamically.

setPlayReverseAnimation(boolean isReverseAnimationEnabled)

• If set true, loading will reverse from the point user stopped touching to 0. If set false, loading will disappear instantly.
  Default value is true.

setStopWhenFilled(boolean stopWhenFilled)

• If set true, loading will stop when it's completed. If set false, loading will be reversed /disappear even if it is filled.
  Default value is true;

setHoldAtLastPosition(boolean isHoldAtLastPosition)

• If set true, progress will not be reverted or reset when user lifts up his/her finger. This will suppress stopWhenFilled and setPlayReverseAnimation.
  Default value is false.

setColorAnimator(int startingColor, int endingColor)

• When set, changes color of loading animation up to progress, starting with startingColor and ending with endingColor.
  There is no color animation by default.

setStrokeColor(int color)
setStrokeColor(String color)

• Set loading's color. Default color is Color.GREEN ( HoldToLoadLayout.DEFAULT_COLOR ).
  Does NOT updates color dynamically.

setDuration(int durationInMillis)

• Set duration of fill time in milliseconds. This will throw IllegalArgumentException if durationInMillis is not greater than 0.
  Default value is 1500 ( HoldToLoadLayout.DEFAULT_DURATION ).

setStrokeAlpha(int alpha)

• Set paint's alpha value. This will throw IllegalArgumentException if alpha is less than 0 or greater than 255.
  Default value is 255 ( HoldToLoadLayout.DEFAULT_ALPHA ).

setStartAngle(Angle startAngle)

• Set loading's starting point from pre-defined angles. Default value is Angle.TOP

setStartAngle(float startAngle)

• Set loading's starting point as angle. Default value is 270 ( top ) ( HoldToLoadLayout.DEFAULT_START_ANGLE ).
  

setFillListener(FillListener fillListener)

• Set a fill listener ( HoldToLoadLayout.FillListener() ), which has onFull(), onEmpty(), onAngleChanged(float angle) and onOffsetChanged(float offset)methods.
  Setting null will remove the listener.

setFillListener(FillListener fillListener)

• Set a fill listener ( HoldToLoadLayout.FillListener() ), which has onFull(), onEmpty() and onAngleChanged(float angle) methods.

removeFillListener()

• Removes fill listener.

Add it in your root build.gradle at the end of repositories:

allprojects {
  repositories {
   ...
   maven { url "https://jitpack.io" }
  }
 }

Add library dependency to your build.gradle file:

dependencies {    
     compile 'com.github.melihaksoy:HoldToLoadLayout:1.0.7'
}
