Question

I’ve being trying to display two graphics in one screen but I’m not able. Here is the code where i show one graphic inside the onClick function:

case R.id.graphs:
            GraphicalView mChartView = new Niveau().execute(this);
            LinearLayout layout = (LinearLayout) findViewById(R.id.graph);
            layout.removeAllViews();
            layout.addView(mChartView, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
            break;

Any idea??

Thank you very much!

Answer 1

case R.id.graphs:
        GraphicalView mChartView1 = new Niveau().execute(this);
        GraphicalView mChartView2 = //  another chartView creation
        LinearLayout layout = (LinearLayout) findViewById(R.id.graph);
        layout.removeAllViews();
        layout.addView(mChartView1, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        layout.addView(mChartView2, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        break;

That should work. Be sure to have different ids on your mChartView – if you create them programmatically and not inflated from an XML layout, you need to set the id programmatically too:

mChartView1.setId(1);
mChartView2.setId(2);

Also, a RelativeLayout would probably offer you more customization in term of layout and positionning. You then need to set the relative positions in your layout params:

RelativeLayout layout = (RelativeLayout) findViewById(R.id.graph);
....
RelativeLayout.LayoutParams paramsForChart2 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
paramsForChart2.addRule(RelativeLayout.RIGHT_OF, mChartView1.getId());
layout.addView(mChartView2, paramsForChart2);
