Question

I’m trying to make some graphics in my application with the AchartEngine API but it doesn’t works.

Can anyone explain me how to have a view with a graphic instead of Intent?

Cause in the demo code it’s only by Intent, not by view.

edit:
I tried to test the 2 options at the same time:
I have a linearLayout with a button in it:

<LinearLayout android:id="@+id/list_infos_layout_stat" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" >

<Button 
    android:id="@+id/list_infos_bouton_stats"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="statistiques"
/>

When I hit the button, a new activity is made by the ChartFactory.getLineChartIntent(..) method and it works great.

And in the same LinearLayout, I put a view returned by ChartFactory.getLineChartView method, its ok I have the graphic at the right of the button.
But when I remove the button I have nothing…

View graphique = new ReponsesChart().getView(contexte);
        if (graphique !=null){
            LinearLayout layout = (LinearLayout)convertView.findViewById(R.id.list_infos_layout_stat);
            layout.addView(graphique, new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
        } else {
            Log.d("Infos", "GRAPHIQUE NULL");
        }

edit 2: Fixed by replacing Fill Parent properties when I add the view to the layout by the width of the screen

In the ChartFactory class there are several methods that you can use like this:

    GraphicalView gView=ChartFactory.getDoughnutChartView(context,data,renderer);

and similar ones for other graph types like line charts and bar charts. You can then simply call:

    setContentView(gView);

Download the documentation for AChartEngine, its pretty easy to find there.
