android-button 背景可绘制对象不起作用

Question

这是我的 xml drawbale 代码，名称为 btntheme.xml :

<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/customactionbartheme_btn_default_normal_holo_light" android:state_enabled="true" android:state_window_focused="false"/>
    <item android:drawable="@drawable/customactionbartheme_btn_default_disabled_holo_light" android:state_enabled="false" android:state_window_focused="false"/>
    <item android:drawable="@drawable/customactionbartheme_btn_default_pressed_holo_light" android:state_pressed="true"/>
    <item android:drawable="@drawable/customactionbartheme_btn_default_focused_holo_light" android:state_enabled="true" android:state_focused="true"/>
    <item android:drawable="@drawable/customactionbartheme_btn_default_normal_holo_light" android:state_enabled="true"/>
    <item android:drawable="@drawable/customactionbartheme_btn_default_disabled_focused_holo_light" android:state_focused="true"/>
    <item android:drawable="@drawable/customactionbartheme_btn_default_disabled_holo_light"/>

</selector>

我已将所有具有这些名称的图像放在 drawable-hdpi 文件夹中。

这是我的布局和按钮:

<Button
                android:id="@+id/button1"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="50"
                android:background="@drawable/btntheme"
                android:textSize="@dimen/font_size_smallerButton" />

它不工作，它根本不改变按钮主题？

你能帮我解决一下吗？

谢谢

尝试添加 <?xml version="1.0" encoding="utf-8"?>在 xml 文件和 xml 文件中会喜欢

<?xml version="1.0" encoding="utf-8"?>


<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Non focused states -->
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/custom_tab_indicator_unselected" />
    <item android:state_focused="false" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/custom_tab_indicator_selected" />

    <!-- Focused states -->
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/custom_tab_indicator_unselected_focused" />
    <item android:state_focused="true" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/custom_tab_indicator_selected_focused" />

    <!-- Pressed -->
    <!--    Non focused states -->
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/custom_tab_indicator_unselected_pressed" />
    <item android:state_focused="false" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/custom_tab_indicator_selected_pressed" />

    <!--    Focused states -->
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/custom_tab_indicator_unselected_pressed" />
    <item android:state_focused="true" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/custom_tab_indicator_selected_pressed" />
</selector>

在使用它之后，如果它不起作用，那么如果可能的话，尝试使用 ImageView 而不是按钮，我认为这会起作用。谢谢;-)
