推荐答案

我找到了一个工作around.I我基本上增加了layout_marginBottom = - 4DP我的进度和包裹它的RelativeLayout内，它对准的底部父view.This变化可能会破坏你的应用程序选择以后更好的解决方案设计与自己的自定义绘制一个自定义的进度条，你可以正确地调整和占用更少的空间帆布相比，progressBarStyleHorizo​​ntal。

I found a work around.I am basically adding a layout_marginBottom="-4dp" to my ProgressBar and wrapped it inside a RelativeLayout and aligned it to the bottom of the parent view.This changes may break your app in the future.For a better solution design a custom progress bar with your own custom drawable which you can align correctly and occupies less canvas space compared to the progressBarStyleHorizontal.

<?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"
android:layout_alignParentBottom="true">

<ImageButton
android:id="@+id/imageButton"
android:layout_width="40dip"
android:layout_height="match_parent"
android:background="@android:color/transparent"
android:contentDescription="@string/descrp"
android:scaleType="center"
android:src="@drawable/some_drawable"
android:visibility="visible" />

<TextView
android:id="@+id/textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:textColor="#FFFFFF"
android:textStyle="bold" />
//changes
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ProgressBar
        android:id="@+id/some_other_id"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="match_parent"
        android:layout_height="10dp"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="-4dp" />
</RelativeLayout></RelativeLayout>
