问题描述

我正在尝试使用aChartEngine显示折线图，但是页面空白，并且收到错误 eglSurfaceAttrib未实现

I am trying to display a line graph using aChartEngine, however, the page is coming up blank and I am receiving the error "eglSurfaceAttrib not implemented"

代码进度（显示）页面：

Code for Progress(display) page:

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:paddingBottom="@dimen/activity_vertical_margin"
     android:paddingLeft="@dimen/activity_horizontal_margin"
     android:paddingRight="@dimen/activity_horizontal_margin"
     android:paddingTop="@dimen/activity_vertical_margin"
     tools:context=".LineGraph" >


     </RelativeLayout>

LineGraph.java的代码：

Code for LineGraph.java :

    package com.lifematters;

    import org.achartengine.ChartFactory;
    import org.achartengine.model.TimeSeries;
    import org.achartengine.model.XYMultipleSeriesDataset;
    import org.achartengine.renderer.XYMultipleSeriesRenderer;
    import org.achartengine.renderer.XYSeriesRenderer;

    import android.app.Activity;
    import android.content.Context;
    import android.content.Intent;
    import android.os.Bundle;

    public class LineGraph extends Activity {

//define layout
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.progress);
}

public Intent getIntent(Context context)
{

    int[] x = {1, 2, 3, 4, 5, 6, 7}; //x values
    int[] y = {3, 2, 3, 4, 2, 1, 3}; //y values

    //need to create series as graph does not support arrays
    TimeSeries series = new TimeSeries("Line1");
        for( int i = 0; i < x.length; i++)
        {
            series.add(x[i], y[i]);
        }

    //allows more than 1 line to be added to linegraph
    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();

    dataset.addSeries(series);

    //customize lines
    XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();
    XYSeriesRenderer renderer = new XYSeriesRenderer();
    mRenderer.addSeriesRenderer(renderer);

    Intent intent = ChartFactory.getLineChartIntent(context, dataset, mRenderer,
             "Line Graph Title");
            return intent;


       }

          }

.MainActivity的代码：

Code for .MainActivity :

    package com.lifematters;

    import android.os.Bundle;
    import android.app.Activity;
    import android.content.Intent;
    import android.view.View;
    import android.widget.ImageButton;

    public class MainActivity extends Activity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

      //define Navigation Image Buttons
      final ImageButton progressBtn = (ImageButton) findViewById(R.id.ImagebtnProgress);


      //Set up listener for Progress
      progressBtn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            //listener call this function
            openProgress();
        }
    });

        }

        //Open progress page
        public void openProgress() {
        //create new textview
        Intent i = new Intent(getApplicationContext(), LineGraph.class);
        startActivity(i);
        }

        public void lineGraphHandler (View view)
        {
        LineGraph line = new LineGraph();
        Intent lineIntent = line.getIntent(this);
        startActivity(lineIntent);
        }

        }
