android - Set ImageView from SDcard to match_parent height? -


so have actiondialog saves signature. when set imageview new captured signature way tall. below illustrate problem

right @ default screen looks this

(textview)-(--edittext--)-(space)-
(textview)-(--edittext--)-(space)-
(textview)-(imageview)-(button)-

after user clicks button asks signature, saves signature, replaces default imageview new bitmap. ends looking this

(textview)-(--edittext--)-(space)-
(textview)-(--edittext--)-(space)-





(textview)-(imageview)-(button)-

i'm unsure why happening. here xml layout

<?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="@drawable/twoglobe_line" android:gravity="center" android:orientation="vertical" >  <linearlayout     android:id="@+id/sigll3"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal" >      <textview         android:id="@+id/textview3"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="1"         android:gravity="center"         android:text="@string/title"         android:textappearance="?android:attr/textappearancesmall" />      <edittext         android:id="@+id/edittext2"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="2"         android:ems="10" >          <requestfocus />     </edittext>      <space         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="1" /> </linearlayout>  <linearlayout     android:id="@+id/sigll1"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal" >      <textview         android:id="@+id/textview1"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="1"         android:gravity="center"         android:text="@string/print_name"         android:textappearance="?android:attr/textappearancesmall" />      <edittext         android:id="@+id/edittext1"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="2"         android:ems="10" >          <requestfocus />     </edittext>      <space         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="1" /> </linearlayout>  <linearlayout     android:id="@+id/sigll2"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal" >      <textview         android:id="@+id/textview2"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="1"         android:gravity="center"         android:text="@string/signature"         android:textappearance="?android:attr/textappearancesmall" />      <imageview         android:id="@+id/sig_image"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="2"         android:src="@drawable/sig" />      <button         android:id="@+id/signature"         style="?android:attr/borderlessbuttonstyle"         android:layout_width="0dp"         android:layout_height="match_parent"         android:layout_weight="1"         android:text="@string/sign" /> </linearlayout> </linearlayout> </scrollview>

i make new bitmap same height button , textview next it. or as possible. can offer

use pixels scale image according textview or whatever per device, scale bitmap accordingly

public static int dptopixels(context context, float dp) {     final float scale = context.getresources().getdisplaymetrics().density;     return (int) (dp * scale + 0.5f); }

then in code after this

bitmap bmp = bitmapfactory.decodefile(mysig                                 .getabsolutepath()); bmp = bitmap.createscaledbitmap(bmp,bmp.getwidth(),dptopixels(this,20)); //or dp
