问题 I have a graph and I need the Y axis to display to 1dp. This works by doing the following code. NumberFormat nf = NumberFormat.getInstance(); nf.setMinimumFractionDigits(1); graph.getGridLabelRenderer().setLabelFormatter(new DefaultLabelFormatter(nf, nf)); I need the X axis to display 2 strings, 1 at the beginning and 1 at the end. This works by doing the following code. StaticLabelsFormatter staticLabelsFormatter = new StaticLabelsFormatter(graph); staticLabelsFormatter.setHorizontalLabels

Android/Java creating a helper class to create graphs

由 一世执手 提交于 2019-12-10 19:32:08

Here is what the code looks like for one of those fragments (this code currently works correctly): public class GyroscopeFragment extends Fragment implements SensorEventListener { private final short TYPE_GYROSCOPE = Sensor.TYPE_GYROSCOPE; private final short POLL_FREQUENCY = 100; //in milliseconds private

问题 I have big problem with understanding multi threading in my application and because of that finding a bug. I've checked I think all possibilities and still I am getting various (sometimes unexpected) errors. Maybe someone here will be able to advice me, what I should do. In my project I am using two external libraries: GraphView - provides views for graph drawing EventBus - provides interface for easy communication between app components As for the app it has the structure like this:
