选定的ListView行设置背景 [英] Set background of a selected listview row

问题描述

我有被填充的位置，当你点击这个带来了就业机会，这个位置内完成一个位置的列表视图。当所有的工作已经完成，然后你点击一个OK按钮，现在在这一点上我想在ListView背景颜色选定位置的行改变。
我至今该按钮是什么

I have a listview which is populated with locations, When you click on a location this brings up jobs to be done within this location. When all jobs have been completed you then click on a ok button now at this point I want the selected location row in the listview background colour to change. What I have so far for the button

 mOkBtn.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            View listView = getActivity().findViewById(R.id.area_list);  
            listView.setBackgroundColor(Color.GREEN);
            mArea.checkResult = CheckResult.OK;
            mArea.checkTimeStamp = System.currentTimeMillis()/1000L;
            showResults();
        }
    });

目前，这改变了整个列表视图绿色，但林不知道如何得到它改变的只是选定行。

At the moment this changes the whole listview green, but im not sure how to get it to change just the selected row.

推荐答案

有关设置颜色，你需要一个选择。您可以使用Android的清单上设置此：listSelector属性为：

For setting the colour, you need a selector. You can set this on your list using the android:listSelector attribute as :

 <ListView 
 android:id="@+id/foodlistview"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:cacheColorHint="#00000000"
 android:scrollbarFadeDuration="0"
 android:divider="@android:color/white"
 android:dividerHeight="2px"
 android:listSelector="list_selector"
 ></ListView>

和list_selector.xml：

And list_selector.xml :

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_enabled="false" android:state_focused="true"
        android:drawable="@drawable/item_disabled" />
  <item android:state_pressed="true"
        android:drawable="@drawable/item_pressed" />
  <item android:state_focused="true"
        android:drawable="@drawable/item_focused" />
</selector>
