LinearLayout填充背景百分比 [英] LinearLayout Fill Percent Of Background

问题描述

我正在尝试填充（水平）项目背景的某个百分比。

I am trying to fill a certain percent of a (horizontal) item's background.

我试过这个，因为很多人推荐：

I have tried this as many people have recommended:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#fff"
    android:orientation="horizontal"
    android:weightSum="1"
    android:baselineAligned="false">

    <LinearLayout
        android:id="@+id/fill_layout"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight=".5"
        android:background="#000"
        android:orientation="horizontal">
    </LinearLayout>

</LinearLayout>

但问题是我在下面有更多的布局，这个布局结束了将其余部分推到了正确如此：

But the problem is that I have many more layout's below that and this layout end's up pushing the rest to the right like so:

如何使这个新的LinearLayout背景布局落后于其余部分布局？这是我的完整xml：

How do I make this new LinearLayout background layout go behind the rest of the layouts? Here is my full xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/item"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="@dimen/activity_horizontal_margin"
    android:background="@color/optionItemBackgroundColor"
    android:clickable="true"
    android:focusable="true"
    android:foreground="?selectableItemBackground"
    android:orientation="horizontal"
    android:weightSum="100"
    android:baselineAligned="false">

    <LinearLayout
        android:id="@+id/fill_layout"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="50"
        android:background="@color/percent_fill_color"
        android:orientation="horizontal">
    </LinearLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minHeight="?listPreferredItemHeight"
        android:orientation="vertical"
        android:weightSum="3">

        <TextView
            android:id="@+id/percentText"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginStart="@dimen/activity_vertical_margin"
            android:layout_weight="2"
            android:gravity="center"
            android:textColor="@color/optionItemTextColor"
            android:textSize="@dimen/option_text_size"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/votesText"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginStart="@dimen/activity_vertical_margin"
            android:layout_weight="1"
            android:gravity="center"
            android:textColor="@color/optionItemTextColor"
            android:textSize="@dimen/num_votes_text_size"
            android:textStyle="normal" />
    </LinearLayout>

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_marginStart="@dimen/activity_vertical_margin"
        android:gravity="center_vertical"
        android:minHeight="?listPreferredItemHeight"
        android:textColor="@color/optionItemTextColor"
        android:textSize="@dimen/option_text_size" />

</LinearLayout>
