【问题描述】:
我有一个带有 TabWidget 的 TabHost。我想自定义选项卡的选定和未选定状态。我不确定如何将所有这些 XML 文件放在一起,以便我可以自定义选项卡?
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp" />
</LinearLayout>
</TabHost>
这是我的选择器 xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Active tab -->
<item android:state_selected="true" android:state_focused="false"
android:state_pressed="false" android:drawable="@drawable/tab_selected" />
<!-- Inactive tab -->
<item android:state_selected="false" android:state_focused="false"
android:state_pressed="false" android:drawable="@drawable/tab_deselected" />
<!-- Pressed tab -->
<item android:state_pressed="true" android:drawable="@android:color/transparent" />
<!-- Selected tab (using d-pad) -->
<item android:state_focused="true" android:state_selected="true"
android:state_pressed="false" android:drawable="@android:color/transparent" />
</selector>
这里是选中状态:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#97150c" android:centerColor="#7F7F7F"
android:endColor="#b4190d" android:angle="-90" />
</shape>
这里是未选中状态:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#acacac" android:centerColor="#7F7F7F"
android:endColor="#d7d7d7" android:angle="-90" />
</shape>
