This is the code I wrote using the GraphView website:
package com.example.sander.app;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import com.jjoe64.graphview.GraphView;
import com.jjoe64.graphview.series.DataPoint;
import com.jjoe64.graphview.series.LineGraphSeries;
/**
* Created by Sander on 8-4-2017.
*/
public class GraphFrame extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_graph,
container, false);
GraphView graph = (GraphView) view.findViewById(R.id.graph);
LineGraphSeries<DataPoint> series = new LineGraphSeries<>(new DataPoint[] {
new DataPoint(0, 1),
new DataPoint(1, 5),
new DataPoint(2, 3),
new DataPoint(3, 2),
new DataPoint(4, 6)
});
graph.addSeries(series);
return view;
}
}
This is the matching XML
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<com.jjoe64.graphview.GraphView
android:layout_width="match_parent"
android:layout_height="200dip"
android:id="@+id/graph" />
</RelativeLayout>
The points I defined inside the LineGraphSeries won't show on the graph. I've used the almost the same example as on android-graphview.org Could anyone help me fix this
Try this, should work.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.fragment_graph);
GraphView graph = (GraphView) findViewById(R.id.graph);
LineGraphSeries<DataPoint> series = new LineGraphSeries<>(new DataPoint[] {
new DataPoint(0, 1),
new DataPoint(1, 5),
new DataPoint(2, 3),
new DataPoint(3, 2),
new DataPoint(4, 6)
});
graph.addSeries(series);
}
}
