我想從achartengine的示例餅圖代碼中使用代碼。在添加代碼和庫時，應用程序崩潰。我添加了這個庫：achartengine-1.0.0.jar使用Buildpath - > configure build path - > libraries - >添加外部jar。問題添加庫：找不到類
但是這個庫顯示在被引用的庫中，而不是在eclipse的私有庫中顯示。 我使用此示例代碼：
code = new String[] {
"Eclair & Older", "Froyo", "Gingerbread", "Honeycomb",
"IceCream Sandwich", "Jelly Bean"
};
// Pie Chart Slice Values
double[] distribution = { 3.9, 12.9, 55.8, 1.9, 23.7, 1.8 } ;
// Color of each Pie Chart Slices
int[] colors = { Color.BLUE, Color.MAGENTA, Color.GREEN, Color.CYAN, Color.RED,
Color.YELLOW };
// Instantiating CategorySeries to plot Pie Chart
CategorySeries distributionSeries = new CategorySeries(" Android version distribution as on October 1, 2012");
for(int i=0 ;i < distribution.length;i++){
// Adding a slice with its values and name to the Pie Chart
distributionSeries.add(code[i], distribution[i]);
}
// Instantiating a renderer for the Pie Chart
DefaultRenderer defaultRenderer = new DefaultRenderer();
for(int i = 0 ;i<distribution.length;i++){
// Instantiating a render for the slice
SimpleSeriesRenderer seriesRenderer = new SimpleSeriesRenderer();
seriesRenderer.setColor(colors[i]);
seriesRenderer.setDisplayChartValues(true);
// Adding the renderer of a slice to the renderer of the pie chart
defaultRenderer.addSeriesRenderer(seriesRenderer);
}
defaultRenderer.setChartTitle("Android version distribution as on October 1, 2012 ");
defaultRenderer.setChartTitleTextSize(20);
defaultRenderer.setZoomButtonsVisible(true);
// Getting a reference to view group linear layout chart_container
// Getting PieChartView to add to the custom layout
mChart = ChartFactory.getPieChartView(getBaseContext(), distributionSeries, defaultRenderer);
// Adding the pie chart to the custom layout
contentView.addView(mChart);
和應用程序崩潰，並顯示以下錯誤：
