我通过使用自定义标签(以点的形式显示标签)添加了视图寻呼机。根据我的要求,三个点应朝下,如下图所示。
Code:
default_dot.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape
android:innerRadius="0dp"
android:shape="ring"
android:thickness="6dp"
android:useLevel="false">
<solid android:color="@android:color/darker_gray"/>
</shape>
</item>
</layer-list>
selected_dot.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape
android:innerRadius="0dp"
android:shape="ring"
android:thickness="6dp"
android:useLevel="false">
<solid android:color="@color/colorAccent"/>
</shape>
</item>
</layer-list>
tab_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/selected_dot"
android:state_selected="true"/>
<item android:drawable="@drawable/default_dot"/>
</selector>
pagerlayout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<LinearLayout
android:id="@+id/mainLinearlayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:id="@+id/lin_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="2">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Total"
android:textSize="20sp"
android:layout_weight="1"/>
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
app:tabBackground="@drawable/tab_selector"
android:layout_weight="1"
app:tabIndicatorHeight="0dp"/>
</LinearLayout>
<Button
android:layout_width="20dp"
android:layout_height="4dp"
android:background="@color/bean_green"
android:layout_gravity="center_horizontal"/>
</LinearLayout>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/viewPager"
android:layout_below="@+id/mainLinearlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</RelativeLayout>
有了上面的代码,我在点之间得到了很多空间。但是按照要求,点应该如图所示。我尝试提供选项卡的布局和边距,但没有用。谁能告诉我如何缩小点之间的间距并精确对准右角。谢谢。
