我正在尝试使用 SwipeRefreshLayout 和工具栏,但每次我同时使用进度圈时都会出现在工具栏上,这在设计方面真的很糟糕。我尝试将 SwipeRefreshLayout 放在工具栏下,但这不起作用,进度圈仍然出现在它的顶部(状态栏上方)。我想像在 Gmail 应用程序中一样同时使用工具栏和布局。我正在使用 AppCompat 库。
这是我的代码:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/swipe_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<include layout="@layout/bluetooth_toolbar"
android:id="@+id/bluetooth_toolbar"/>
<TextView
android:id="@+id/swipeTo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Swipe down to refresh"
android:textSize="20sp"
android:layout_below="@+id/bluetooth_toolbar"
android:layout_centerHorizontal="true" />
<ListView
android:id="@+id/newDevices"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/swipeTo"
android:layout_marginTop="50dp" />
<ListView
android:id="@+id/pairedDevices"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/newDevices"
android:layout_marginTop="50dp" />
</RelativeLayout>
</ScrollView>
</android.support.v4.widget.SwipeRefreshLayout>
