java - ImageView is NOT SHOWING in a linear layout (android) -


i'm creating android application , got issues in first stage.

i'm trying display image imageview inside layout.

my code follows:

activity_starter.xml:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:background="@color/white"     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=".starteractivity" >      <imageview         android:id="@+id/starterpic"         android:layout_width="0dp"         android:layout_height="160dp"         android:layout_gravity="center"         android:layout_weight="0.84"         android:adjustviewbounds="true"         android:contentdescription="@string/app_name"         android:src="@drawable/ic_launcher"         android:visibility="visible" />  </linearlayout>

and starteractivity.java:

    protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_starter);         log.i(log_tag, "entered starter screen");          imageview mimageview = (imageview) findviewbyid(r.id.starterpic);          mimageview.setscaletype(imageview.scaletype.fit_center);         mimageview.setimageresource(r.drawable.ic_launcher);         mimageview.setvisibility(imageview.visible);         mimageview.invalidate(); }

the issues are:

  1. i can't hide title bar on top (black bar says "whereisit" (app. name)).
  2. the image in imageview not shown.

i've been digging hours, doing wrong?

to hide title bar , need put code in oncreate method :

    @override     protected void oncreate(bundle savedinstancestate) {             super.oncreate(savedinstancestate);             requestwindowfeature(window.feature_no_title); //add line              setcontentview(r.layout.activity_starter);              // rest of code          }
