Android的列表视图不再突出选择的onclick [英] Android listview no longer highlights selection onclick

问题描述

我有一个是显示，当我接触了他们对项yellowtint列表视图。所有我所做的不同是改变背景图像中的列表视图XML，现在它不再会告诉我yellowtint

I have a listview that was showing a yellowtint on items when I touched them. All I've done differently is change the background image in that listview xml , and now it no longer will show me the yellowtint

下面是code

列表视图中的XML，它仅仅是一个与背景图像TextView的：

the list view xml, it is just a textview with a background image:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:padding="10dp"
    android:textSize="24sp"
    android:textColor="#000000"
    android:background="@drawable/bglistitem"
    android:gravity="center_vertical|center_horizontal">
</TextView>

在那里它被称为在另一个布局的地方

the place in another layout where it is called

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:padding="10dp"
    android:textSize="24sp"
    android:textColor="#000000"
    android:background="@drawable/bglistitem"
    android:gravity="center_vertical|center_horizontal">
</TextView>

和这里是code：

lv.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> arg0, View arg1,int arg2, long arg3) {}
});

，你可以在上面看到的，我从来没有做任何事情，会改变选择高亮的默认行为，为什么会这样，现在是不同的，你看，我不认为或许是？

as you can see above, I was never doing anything that would change the default behavior of the selection highlighting, why would this be different now, perhaps something you see that I don't see?

推荐答案

当你添加了一个新的背景到ListView你推翻机器人这是最有可能使用一个选择器着色取决于他们的状态ListItems的默认背景。

When you added a new background to the ListView you overrode androids default background that was most likely using a selector to tint the ListItems depending on their state.

尝试使用自定义选择

创建一个XML文件，mycustombackground.xml，并且将其添加到它：

Create an XML file, mycustombackground.xml, and add this to it:

<?xml version="1.0" encoding="utf-8"?>
 <selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:state_pressed="true"
      android:drawable="@drawable/item_pressed" /> 
   <item android:state_focused="true"
      android:drawable="@drawable/item_focused" /> 
   <item android:drawable="@drawable/item_normal" /> 
 </selector>

替换为自己的@drawables相对于状态。 那么你的列表视图的背景设定在XML文件中。

Replace the @drawables with your own in relation to the state. Then set the background of your listview to the xml file.

android:background="@drawable/mycustombackground" 

您可能想看看到XML创建黄色，或者只是创建自己的形象。

You may want to take a look into the XML to create the yellow color, or just create your own image.
