IncDec Android UI Library

Incrementor and Decrementor (IncDec)

IncDec library will allow you to perform increment and decrement operation. As it supports single click and long press, it enhances UX solving the delay problem in the typical number picker.

  • IncDec can be used as an alternate for numberpicker, for fast number picking. User need not scroll the wheel for long time. He can just press and hold the button and IncDec will do it's magic.
  • For usecases like shopping cart quantity, medicine units, setting up time and medicine quantity, IncDec will hold good

Why IncDec ?

  • It is based on skeuomorphism concept of picking a number.
  • simple and auto-explanatory to the user
  • Allows user to quickly pick things
  • Supports Array values, Integer and float values
  • Highly flexible (supporting color, drawable, speed etc.)
  • Long press and single tap support
  • FAB and ImageButton support

Using IncDec Library in your application

Add this in your build.gradle

compile 'com.hariofspades.IncDec:incdeclibrary:0.0.5'

Adding IncDec FAB in to the XML

<com.hariofspades.incdeclibrary.IncDecCircular
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:textSize="44"
        android:id="@+id/incdec"
        app:textColor="@color/white"
        app:leftButtonColorTint="@color/colorPrimaryDark"
        app:rightButtonColorTinit="@color/colorPrimary"
        app:leftDrawableTint="@color/white"
        app:rightDrawableTint="@color/white"
        app:leftDrawable="@drawable/ic_remove_black_24dp"
        app:rightDrawable="@drawable/ic_add_black_24dp"/>

Setting up Array values to IncDec

ArrayList<String> values=new ArrayList<>();
        values.add("Apple");
        values.add("Ball");
        values.add("Cat");
        values.add("Dog");
        values.add("Elephant");
        
 IncDecCircular incdec=(IncDecCircular)findViewById(R.id.incdec);
 incdec.setConfiguration(LinearLayout.HORIZONTAL,IncDecCircular.TYPE_ARRAY,
                IncDecCircular.DECREMENT,IncDecCircular.INCREMENT);
 incdec.setArrayList(values);
 incdec.setArrayIndexes(1,3,1);
 incdec.enableLongPress(true,true,500);

Decoding the above function parameters

setConfiguration - Layout's orientation, type(array,integer,float),left button (increment/decrement), right button (increment/decrement)

setArrayList - arraylist values

setArrayIndexes - starting index, stoping index, interval count

enableLongPress - for left button, right button and the speed in ms for counting

Making IncDec behave for float values

IncDecCircular incdec =(IncDecCircular) findViewById(R.id.incdec);
incdec.setConfiguration(LinearLayout.VERTICAL,IncDecCircular.TYPE_FLOAT,
                IncDecCircular.INCREMENT,IncDecCircular.DECREMENT);
incdec.setupValues(2,40,(float)0.7,10);
incdec.setprecision("%.1f");
incdec.enableLongPress(false,false,500);

Decoding function parameters

setupValues - intial value final value, interval and start value

setprecision - Restricting decimal places

Making IncDec behave for integers

IncDecCircular incdec=(IncDecCircular)findViewById(R.id.incdec);
incdec.setConfiguration(LinearLayout.HORIZONTAL,IncDecCircular.TYPE_INTEGER,
                IncDecCircular.DECREMENT,IncDecCircular.INCREMENT);
incdec.setupValues(0,20,1,4);
incdec.enableLongPress(true,true,500);

Listeners for IncDec

 incdec.setOnClickListener(new IncDecCircular.OnClickListener() {
            @Override
            public void onClick(View view) {
                //For Array
                Toast.makeText(MainActivity.this,
                        String.valueOf(incdec.getCurrentIndex()), Toast.LENGTH_SHORT).show();
                //For int and float
                Toast.makeText(MainActivity.this,
                        incdec.getValue(), Toast.LENGTH_SHORT).show();
            }
        });
        
  incdec.setOnValueChangeListener(new IncDecCircular.OnValueChangeListener() {
            @Override
            public void onValueChange(IncDecCircular view, float oldValue, float newValue) {
                Toast.makeText(MainActivity.this, String.valueOf(oldValue)+"/"+
                        String.valueOf(newValue), Toast.LENGTH_SHORT).show();
            }
        });
    

IncDec for traditional ImageButton

 <com.hariofspades.incdeclibrary.IncDecImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:textSizeB="24"
        android:id="@+id/incdec"
        android:layout_marginTop="20dp"
        app:textColorB="@color/white"
        app:leftButtonColorTintB="@color/colorPrimaryDark"
        app:rightButtonColorTinitB="@color/colorPrimary"
        app:leftDrawableTintB="@color/white"
        app:rightDrawableTintB="@color/white"
        app:leftDrawableB="@drawable/ic_remove_black_24dp"
        app:rightDrawableB="@drawable/ic_add_black_24dp"/>

For Adding your own Background for ImageButton

    IncDecImageButton incdecImg2=(IncDecImageButton) findViewById(R.id.incdecbut2);
    incdecImg2.setBackgroundforButton(ContextCompat.getDrawable(this,R.drawable.round),
                    ContextCompat.getDrawable(this,R.drawable.round));

#Decoding function parameters setBackground - leftbutton background, right button background

Note : By default, the background of the image button will be transparent. You can add lefttint and righttint for colours.

##Happy Coding!!
