i thought had set layout seems isnt.

update: how set scroll view 2 linear layouts in it.

<?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="wrap_content" android:orientation="vertical" >  <linearlayout     android:layout_width="match_parent"     android:layout_height="84dp"     android:orientation="horizontal" >      <imageview         android:id="@+id/imglink"         android:layout_width="78dp"         android:layout_height="wrap_content"         android:layout_gravity="center_vertical"         android:src="@drawable/appointmentmanimenuicon" />        <textview         android:id="@+id/textview1"         android:layout_width="match_parent"         android:layout_height="75dp"         android:gravity="center"         android:text="appointments"         android:textappearance="?android:attr/textappearancelarge"         android:textsize="30sp" /> </linearlayout>       <scrollview         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:fillviewport="true">      <linearlayout         android:layout_width="match_parent"         android:layout_height="200dp"         android:orientation="vertical" >      <button         android:id="@+id/btnaddappoint"         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_margin="50dp"         android:drawableleft="@drawable/appointmentmenu"         android:src="@drawable/appointmentmenu"         android:text="add appointment"         android:layout_weight="1" />      </linearlayout>         <linearlayout         android:layout_width="match_parent"         android:layout_height="200dp"         android:orientation="vertical" >     <button         android:id="@+id/btnviewappoint"         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_margin="50dp"         android:drawableleft="@drawable/appointviewicon"         android:src="@drawable/appointviewicon"         android:text="view appointments"         android:layout_weight="1" /> </linearlayout> </scrollview> </linearlayout>

your nested linear layout buttons has fixed height of 400dp. on small device leaves smaller amount of space @ bottom on larger nexus4.

if change linear layout buttons use height value of fill_parent should place buttons evenly in space remaining in parent layout underneath header ( contacts).

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
