Check this image for the progressbar
知道如何消除ProgressBar下的那个小差距吗? 我怎么能没有差距?应该是通过MainActivity中的java代码还是......? 这是我的布局xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.v7.widget.Toolbar
android:id="@+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="wrap_content"
android:layout_height="2.9dp"
android:id="@+id/progressBar"
android:background="@android:color/transparent"
android:layout_alignParentStart="true"
android:layout_alignParentEnd="true"
android:layout_alignBottom="@id/my_toolbar"/>
<WebView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/webView"
android:layout_alignParentEnd="true"
android:layout_alignParentStart="true"
android:layout_below="@+id/my_toolbar"
android:layout_alignParentBottom="true" />
</RelativeLayout>

只为Progressbar
更新代码
