Android RelativeLayout选择器state_pressed不起作用 [英] Android RelativeLayout Selector state_pressed doesn't work

问题描述

我有这样的RelativeLayout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/contacts"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_weight="0.2"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

<ImageView
    android:id="@+id/image"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:contentDescription="@string/content_description_contacts"
    android:scaleType="fitXY"
    android:src="@drawable/contacts" />

<TextView
    android:id="@+id/text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignBottom="@id/image"
    android:paddingBottom="10dp"
    android:textColor="@drawable/text_color"
    android:text="@string/button_contacts"
    android:textSize="12sp" />    
</RelativeLayout>

，看起来像:

我的contacts选择器似乎是:

<?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/contacts_over" />
<item android:state_selected="true"
    android:drawable="@drawable/contacts_selected" />
<item
     android:drawable="@drawable/contacts_default" />
</selector>

如您所见，我有3张图像:默认情况下，已选择并按下.

As you can see I have 3 images: by default, selected and pressed.

但是我有一个问题:只有默认图像和state_selected图像可以正常工作，但是state_pressed似乎不起作用.

But I have a problem: only default and state_selected images are work as expected, but state_pressed dosn't seem to work.

我有几个上面提到的RelativeLayouts，没有人使用state_pressed.

I have several above mentioned RelativeLayouts and no one works with state_pressed.

有人知道我的问题在哪里吗?

Does anybody know where is my problem?

谢谢！
