Question

在XML档案中,我有以下选定人:res/color/redeemlist_item_color.xml:

<?xml version="1.0" encoding="utf-8"?>
   <selector xmlns:android="http://schemas.android.com/apk/res/android">

      <item android:state_pressed="true"
            android:color="#FFFFFF" /> <!-- pressed -->

      <item android:state_selected="true"
            android:color="#FFFFFF" /> <!-- focused -->

      <item android:color="#000000" /> <!-- default -->

   </selector>

I also have a TextView in a ListView item layout. When I set android:textColor on this TextView to the above selector in XML, then the color changes correctly when the item is selected. However, I am trying to set this resource programmatically in the following way:

holder.label.setTextColor(R.color.redeemlist_item_color);

这样,肤色就不再改变。能够以这种方式指派一名选择人到<条码>。

Answer 1

I think you might need to add findViewById or something of that variety

Edit:上述说法不正确,因为根据我的意见,适当的答案是正确的。

setTextColor(getResources().getColorStateList(R.color.redeemlist_item_color));

I was also struggling with this problem, if you want to have use a state list, you need to declare it in the color resources folder, instead of the drawable folder, and use the setTextColor(getResources().getColorStateList(R.color.redeemlist_item_color)).

Answer 3

You can try:

holder.label.setTextColor(getResources().getColor(R.color.redeemlist_item_color));

而不是:

持有人.label.setTextColor(R.color.redeemlist_item_color);

Answer 4

Rasman is correct. You need to give the TextView an ID, android:id="@+/something". You retrieve a reference to that particular using that ID and findViewById, and then you may set the text color.
