A beautiful Android custom View that works similar to a range or seekbar. Selection by gesture. With animations. Supporting API level 11+.

For a short demonstration, please download the demo application from the Google PlayStore. The corresponding code for the demo application can be found in the ValueBarExample folder.

For using ValueBar, either

• clone this repository and add the library folder to your Android application project
• or download the latest .jar file from the release-section and copy it into the libs folder of your Android application project.

Create a ValueBar in .xml:

<com.philjay.valuebar.ValueBar
        android:id="@+id/valueBar"
        android:layout_width="match_parent"
        android:layout_height="60dp"
        android:layout_margin="5dp" />

or in code, and then add it to a layout:

 ValueBar bar = new ValueBar(Context);

Apply styling, and display values:

 bar.setMinMax(0, 1000);
 bar.setInterval(1f); // interval in which can be selected
 bar.setDrawBorder(false);
 bar.setValueTextSize(14f);
 bar.setMinMaxTextSize(14f);
 bar.setValueTextTypeface(...);
 bar.setMinMaxTextTypeface(...);
 
 // create your custom color formatter by using the BarColorFormatter interface
 bar.setColorFormatter(new RedToGreenFormatter());
 
 // add your custom text formatter by using the ValueTextFormatter interface
 bar.setValueTextFormatter(...);
            
 bar.setValue(800f); // display a value
            
 bar.setValueBarSelectionListener(...); // add a listener for callbacks when touching
