Question

my TextView that I add to my LinearLayout is not visible…why ?

layoutVenues = (LinearLayout) findViewById(R.id.layoutv);
layoutVenues.addView(genTextView(v.getName()));
layoutVenues.addView(genLineView());

and the genTextView Method:

public TextView genTextView(String text) {
        TextView tv = new TextView(this);
        tv.setText(text);
        tv.setTextColor(Color.BLACK);
        return tv;
    }

Answer 1

You need to set layout parameters otherwise you will not have a proper layout

public TextView genTextView(String text) {
     TextView tv = new TextView(this);
     LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutPararms.WRAP_CONTENT);
     tv.setLayoutParams(lp);
     tv.setText(text);
     tv.setTextColor(Color.BLACK);
     return tv;
    }
