Menu and a ContextMenu for a aChartengine chart

Question

Is it possible? have anyone been doing this before? I don\'t know where to start.

I mostly need the menu, not the context menu.

My \"BudgetPieChart\" class

To get a menu you need only 1 thing. You have to use GraphicalView on your own activity. In order to do that you'll need:

Former BudgetPieChart class

public class ExpByCatPieChartHelper extends AbstractChart{

    private DataToArray dta;

    @Override
    public String getName() {
        return MyApplication.getContext().getString(R.string.ExpensesByCategoriesPieChartName);
    }

    @Override
    public String getDesc() {
        return "The budget per project for this year (pie chart)";      
    }


    public GraphicalView createView(Context context) {

            dta = new DataToArray();
            String[] categories = dta.expenseByCategoriesToArray();
            double[] values = dta.expensesValuesByCategoriesToArray();      
            int[] colors = dta.getColorsArray(categories.length);           

            DefaultRenderer renderer = buildCategoryRenderer(colors);           
            renderer.setZoomButtonsVisible(true);
            renderer.setZoomEnabled(true);
            renderer.setChartTitleTextSize(20);

            return ChartFactory.getPieChartView(context, buildCategoryDataset("Wydatki kategoriami", categories, values), renderer);
        }

    @Override
    public Intent execute(Context context) {
        return null;
    }


}

Additional class with activity of your own:

public class ExpByCatPieChart extends Activity{

    private IACharts pieChart = new ExpByCatPieChartHelper();

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        GraphicalView mGraphicalView = new ExpByCatPieChartHelper().createView(this);
        setContentView(mGraphicalView);
        super.onCreate(savedInstanceState);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.chart_settings_menu, menu);
        return true;
    }

    @Override
    public boolean onMenuItemSelected(int featureId, MenuItem item) {
        switch(item.getItemId()) {
        case R.id.chart_settings:
            Intent i = new Intent(this, PieChartSettings.class);
            startActivityForResult(i, 0); 
            return true;
        case R.id.home:
            finish();
            return true;
        }
        return super.onMenuItemSelected(featureId, item);
    }



}

And this is pretty much everything. You get a default achart view and seit it as a content of a new activity. Viola :)
