CompassView

Compass view for Android.

This library provides a fully customizable linear compass view.

If configured range > 50 degrees, e.g. setRangeDegrees(180):

If range is <= 50 degrees, e.g. setRangeDegrees(50), numbers are shown:

How to use

Configuring your project dependencies

Add the JitPack repository to your root build.gradle at the end of repositories:

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

Add the library dependency to your build.gradle file.

dependencies {
    ...
    implementation 'com.github.kix2902:CompassView:master-SNAPSHOT'
}

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); //immediate change
compass.setDegrees(57,true); //with animation
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);

compass.getDegrees(); //read current degrees value

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
	}
});
