我试图在ListView中更改文本的颜色,所以我创建了ViewBinder,但我的文本仍然是白色,没有任何变化,该怎么办?

// map each name to a TextView
    String[] from = new String[] { "event" };
    int[] to = new int[] { R.id.countryTextView };
    conAdapter = new SimpleCursorAdapter(Clock.this, R.layout.day_plan, null, from, to);
    setListAdapter(conAdapter); // set adapter

    SimpleCursorAdapter.ViewBinder binder = new SimpleCursorAdapter.ViewBinder() {

        @Override
        public boolean setViewValue(View view, Cursor cursor, int columnIndex){
            int getIndex = cursor.getColumnIndex("colour");
            String color = cursor.getString(getIndex);
           tv = (TextView)findViewById(R.id.countryTextView);

            tv.setTextColor(Color.BLUE);

           if(color.equals("Green"))
            {
                tv.setTextColor(Color.rgb(0,255,0));
                return true;
            }
            return false;
        }};

最佳答案

您打过conAdapter.setViewBinder(SimpleCursorAdapter.ViewBinder)吗?也就是说,您确定实际上正在调用这些方法吗?

还要更改以下几行之一:

       tv = (TextView)view.findViewById(R.id.countryTextView); // <-- add 'view.'
