我试图改变ListView中文本的颜色,所以我创建了ViewBinder,但我的文字仍然是白色的,没有任何变化,我该怎么办呢?
// 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;
}};
答案 0 :(得分:1)
您致电conAdapter.setViewBinder(SimpleCursorAdapter.ViewBinder)
了吗?也就是说,你确定这些方法实际上是被调用的吗?
同时更改其中一行:
tv = (TextView)view.findViewById(R.id.countryTextView); // <-- add 'view.'
