android - LinearLayout doesn't show view -


i'm using linearlayout doesn't show every view.

this xml-code:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="160dp"     android:layout_height="wrap_content"     android:orientation="horizontal"     tools:context="de.schumann_connection.yahtzee.descriptioncolumnfragment">      <view         android:layout_width="1dp"         android:layout_height="match_parent"         android:background="#ff000000" />      <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"         xmlns:tools="http://schemas.android.com/tools"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="vertical"         tools:context="de.schumann_connection.yahtzee.descriptioncolumnfragment">          <view             android:layout_width="match_parent"             android:layout_height="1dp"             android:background="#ff000000" />         <textview             android:layout_width="wrap_content"             android:layout_height="43dp"             android:text=""/>         <view             android:layout_width="match_parent"             android:layout_height="1dp"             android:background="#ff000000" />     </linearlayout>      <view         android:layout_width="1dp"         android:layout_height="match_parent"         android:background="#ff000000" /> </linearlayout>

there more controls contained enough demonstrate problem.

this should draw black rectangle. right vertical line missing. why?

just add weight inner linearlayout android:layout_width="0dp" , android:layout_weight="1"

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="160dp" android:layout_height="wrap_content" android:orientation="horizontal" >  <view     android:layout_width="1dp"     android:layout_height="match_parent"     android:background="#ff000000" />  <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="0dp"     android:layout_weight="1"     android:layout_height="wrap_content"     android:orientation="vertical"     >      <view         android:layout_width="match_parent"         android:layout_height="1dp"         android:background="#ff000000" />     <textview         android:layout_width="wrap_content"         android:layout_height="43dp"         android:text="hola"/>     <view         android:layout_width="match_parent"         android:layout_height="1dp"         android:background="#ff000000" /> </linearlayout>  <view     android:layout_width="1dp"     android:layout_marginright="5dp"     android:layout_height="match_parent"     android:background="#ff000000" />

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
