LinearLayout填充背景的百分比

Question

我想填充（水平）項目背景的某個百分比。

我已經試過這是很多人都推薦：

<?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> 

但問題是，我有更多的佈局的下面這一點，這種佈局最終的向上推動其餘像這樣的權利：

如何讓這個新的LinearLayout背景佈局進入其他佈局的後面？這裏是我完整的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>

如果你正在努力實現這樣試試這個代碼

<?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="#e11f1f" 
    android:orientation="vertical" 
    android:weightSum="1" 
    android:baselineAligned="false"> 

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

</LinearLayout> 

如果你想獲得這個觀點試試這個

<?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>
