Solution 1

try this way. Just override getView() method of you adapter. And change color from there.

AD = new SimpleAdapter(this, data, R.layout.modelo, from, views){
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.modelo, null);
}
TextView text1 = (TextView) v.findViewById(R.id.txttitulo);
TextView text2 = (TextView) v.findViewById(R.id.txtconteudo);
TextView text3 = (TextView) v.findViewById(R.id.textview3);
text1.setTextColor(Color.GREEN);
text2.setTextColor(Color.GREEN);
text3.setTextColor(Color.GREEN);
return super.getView(position, v, parent);
}
};

I hope this will help you.

Solution 2

Check this one,

TextView textView = (TextView) findViewById(R.id.text1);
textView.setText("Welcome");
textView.setTextColor(Color.WHITE);
textView.setBackgroundColor(Color.RED);

Solution 3

This may be Help You.

textview.setBackgroundResource(R.color.white);

Note :instead of textview you need to write your TextView object name.
