Question

I need to dynamically add some tablerows to a linearlayout in my app. I write this code:

LinearLayout tabella = (LinearLayout) findViewById(R.id.tabella_contatori);

    for(int i =0; i<array_list.size(); i++){
        TableRow row = new TableRow(getApplicationContext());
        row.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));

        TextView data = new TextView(getApplicationContext());
        data.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 0.2f));
        data.setTextAppearance(getApplicationContext(), android.R.attr.textAppearanceMedium);
        data.setTextColor(Color.BLACK);
        data.setBackgroundColor(Color.WHITE);
        data.setPadding(2, 0, 0, 0);
        data.setText("asd");

        row.addView(data);
        tabella.addView(row);
    }
}

But when I open the app nothing appens. I already check if array_list.size is bigger than 0.
How can I do?
Thanks, Mattia

The problem is in your TextView Layout Params. The type should be TableRow.LayoutParams not LinearLayout.LayoutParams.
data.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
