How to use

Configuring your project dependencies

Add the library dependency to your build.gradle file.

dependencies {

  ...
  compile 'com.redinput.compassview:compassview:1.0' 
}

Adding and Customizing the View

You can declare a CompassView just like that:

<com.redinput.compassview.CompassView
  android:id="@+id/compass"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  app:backgroundColor="#000000"
  app:showMarker="true"
  app:markerColor="#FF0000"
  app:lineColor="#FFFFFF"
  app:textColor="#FFFFFF"
  app:textSize="15sp"
  app:degrees="0"
  app:rangeDegrees="180.0" />

Property values shown above are the defaults of the CompassView and it can be omitted for brevity.

Also, you can set all that properties with Java.

CompassView compass = (CompassView) findViewById(R.id.compass);
  compass.setDegrees(57);
 compass.setBackgroundColor(Color.YELLOW);
 compass.setLineColor(Color.RED);
 compass.setMarkerColor(Color.BLACK);
 compass.setTextColor(Color.WHITE);
 compass.setShowMarker(false);
 compass.setTextSize(37);
 compass.setRangeDegrees(270);

Another feature is that you can move the 'CompassView' dragging the view horizontally and even you can attach it a 'OnCompassDragListener' to observe the changes on the degrees value.

compass.setOnCompassDragListener(new CompassView.OnCompassDragListener() {
  @Override  public void onCompassDragListener(float degrees) {

// Do what you want with the degrees  
}
 
}
);
