android - Make a view next to another and at the middle of its height -

-

i'm trying make activity numberpicker , textview , want textview next numberpicker , @ middle of numberpicker height (the tv going "choose number:") thing i've tried didn't worked. (i tried put 1 in different linearlayout , 2 linearlayouts in relativelayout , messed prefences , still didn't work)

here tried:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingbottom="@dimen/activity_vertical_margin"    android:paddingleft="@dimen/activity_horizontal_margin"    android:paddingright="@dimen/activity_horizontal_margin"    android:paddingtop="@dimen/activity_vertical_margin"    tools:context=".mainactivity" >      <textview        android:id="@+id/textview1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignparentend="true"        android:paddingtop="30dp"        android:text="@string/main"/>      <numberpicker        android:id="@+id/numberpicker1"        android:layout_width="30dp"        android:layout_height="wrap_content"        android:layout_alignparenttop="true"        android:layout_tostartof="@+id/textview1"        android:clickable="false"        android:paddingtop="0dp" />  </relativelayout>

thanks!

i following kind of situations:

<textview     ...     android:layout_aligntop="@+id/numberpicker1"     android:layout_alignbottom="@+id/numberpicker1"     android:gravity="center_vertical" />

this way tex view appears in middle of number picker. way remind, should put number picker before text view if want try method.

good luck!

i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.
