Gradle Dependency

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

Add the dependency :

dependencies {
	        compile 'com.github.GoodieBag:HorizontalPicker:v1.0'
	}

Sync the gradle and that's it! ????

Features :

  • Supports icons and text or a mixture of both as items of the picker.
  • Tap or scroll horizontally to select the items.
  • Supports drawables, selectors and text highlighting using selectors.
  • Selection change listener to monitor the current selected item.

Usage

XML :

<com.goodiebag.horizontalpicker.HorizontalPicker
            android:id="@+id/hpicker"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:textSize="18sp"
            app:itemMargin="5dp"
            app:itemHeight="40dp"
            app:itemWidth="40dp"
            app:backgroundSelector="@drawable/selector_background_example"
            app:textColorSelector="@color/selector_text_view"/>

P.S : itemWidth and itemHeight are not mandatory. If ignored, it is WRAP_CONTENT by default.
textColorSelector is only applicable when the items are textItems.

Java :

 //If your picker needs to have text as items :  
 HorizontalPicker hpText = (HorizontalPicker) findViewById(R.id.picker);
 
 List<HorizontalPicker.PickerItem> textItems = new ArrayList<>();
        for(int i=1;i<=4;i++){
            textItems.add(new HorizontalPicker.TextItem("S"+i));
        }
  hpText.setItems(textItems,3); //3 here signifies the default selected item. Use : hpText.setItems(textItems) if none of the items are selected by default.
  
 //If your picker takes images as items : 
HorizontalPicker hpImage = (HorizontalPicker) findViewById(R.id.hpImage);
 
List<HorizontalPicker.PickerItem> imageItems = new ArrayList<>();
imageItems.add(new HorizontalPicker.DrawableItem(R.drawable.example));
imageItems.add(new HorizontalPicker.DrawableItem(R.drawable.example2));
hpImage.setItems(imageItems);
Use hpText.setSelectedIndex(index) to select an item programmatically.

Listeners :

A listener exists to monitor the item selection change on slide or on tap.

HorizontalPicker.OnSelectionChangeListener listener = new HorizontalPicker.OnSelectionChangeListener() {
      		@Override
            public void onItemSelect(HorizontalPicker picker, int index) {
                HorizontalPicker.PickerItem selected = picker.getSelectedItem();
                Toast.makeText(MainActivity.this, selected.hasDrawable() ? "Item at " + (picker.getSelectedIndex() + 1) + " is selected" : selected.getText() + " is selected", Toast.LENGTH_SHORT).show();
            }
hpText.setChangeListener(listener);

Known Issues :

When the HorizontalPicker is wrapped in an HorizontalScrollView the scroll to select feature of the picker does not work as expected. This will be fixed soon.
