Ошибка: eglSurfaceAttrib не реализован

Question

Я пытаюсь отобразить график линии с помощью aChartEngine, однако, страница приходит пустой и я получаю сообщение об ошибке «eglSurfaceAttrib не реализованы»

код для прогресса (дисплей) страницы:

<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>

    dataset.addSeries(series); 

    //customize lines

      } 

Код для .MainActivity:

Любая помощь будет оценена. Спасибо

Answer 1

Из журналов ошибок:

android.content.ActivityNotFoundException: Не удается найти явный класс активности {com.lifematters/com.lifematters.LineGraph}; Вы объявили эту активность в своем AndroidManifest.xml?

Answer 2

Попробуйте

public void openProgress() { 
     //create new textview 
     LineGraph line = new LineGraph(); 
     Intent lineIntent = line.getIntent(this); 
     startActivity(lineIntent); 
     } 

ИЛИ

public void openProgress() { 

    lineGraphHandler(); 
    } 

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

Answer 3

добавить этот код для вашей основной деятельности

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Button b2; 
    b2=(Button)findViewById(R.id.button2); 
    b2.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 

      Intent i = new Intent(getApplicationContext(), MyLine.class); 
      startActivity(i); 
     } 
    }); 

я есть сделать свой класс как MyLine так добавить это MyLine класса

package com.isuru.mychater; 

import org.achartengine.ChartFactory; 
import org.achartengine.GraphicalView; 
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; 
import android.widget.RelativeLayout; 

public class MyLine extends Activity{ 



@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.line); 
    //getIntent(this); 
    MyLine line = new MyLine(); 
    GraphicalView gview = line.getView(this); 
    RelativeLayout layout =(RelativeLayout)findViewById(R.id.chart); 
    layout.addView(gview); 
} 

public GraphicalView getView(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); 

    return ChartFactory.getLineChartView(context, dataset, mRenderer); 



     } 

} 

шнур для моего файла line.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" > 

<RelativeLayout 
    android:id="@+id/chart" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentTop="true" > 
</RelativeLayout> 

также не для получения обновления файла манифеста, как

<activity 
     android:name="com.isuru.mychater.MyLine" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MYLINE" /> 

      <category android:name="android.intent.category.DEFAULT" /> 
     </intent-filter> 
    </activity> 
    <activity android:name="org.achartengine.GraphicalActivity"/>
