android - Is it possible to disable scroll on a listView? -
i dynamically add items listview , want make items visible, without scrolling.
layout code:
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/recipe_inside" android:orientation="vertical" > <scrollview android:layout_width="match_parent" android:layout_height="wrap_content" > <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" > <imageview android:id="@+id/imageview1" android:layout_width="match_parent" android:layout_height="16dp" android:src="@drawable/head_cella" /> <textview android:id="@+id/textview1" android:layout_width="wrap_content" android:layout_height="41dp" android:background="@drawable/body_cella" android:gravity="center_horizontal" android:paddingtop="5dp" android:text="remember save before leaving page or inserted/modified data lost." android:textcolor="#000000" android:textsize="13dp" /> <imageview android:id="@+id/imageview01" android:layout_width="match_parent" android:layout_height="16dp" android:layout_margintop="30dp" android:src="@drawable/head_cella" /> <textview android:id="@+id/textview01" android:layout_width="wrap_content" android:layout_height="35dp" android:background="@drawable/body_cella" android:gravity="center_horizontal" android:paddingtop="10dp" android:text="category" android:textcolor="#000000" android:textsize="15dp" /> <spinner android:id="@+id/category_spinner" android:layout_width="match_parent" android:layout_height="wrap_content" /> <imageview android:id="@+id/imageview02" android:layout_width="match_parent" android:layout_height="16dp" android:layout_margintop="30dp" android:src="@drawable/head_cella" /> <textview android:id="@+id/textview02" android:layout_width="wrap_content" android:layout_height="35dp" android:background="@drawable/body_cella" android:gravity="center_horizontal" android:paddingtop="10dp" android:text="name" android:textcolor="#000000" android:textsize="15dp" /> <edittext android:id="@+id/recipe_title" android:layout_width="match_parent" android:layout_height="wrap_content" android:ems="10" android:hint="recipe title" android:lines="1"/> <imageview android:id="@+id/imageview03" android:layout_width="match_parent" android:layout_height="16dp" android:layout_margintop="30dp" android:src="@drawable/head_cella" /> <textview android:id="@+id/textview03" android:layout_width="wrap_content" android:layout_height="35dp" android:background="@drawable/body_cella" android:gravity="center_horizontal" android:paddingtop="10dp" android:text="ingredients" android:textcolor="#000000" android:textsize="15dp" /> <listview android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:cachecolorhint="#00000000" android:divider="#00000000" android:isscrollcontainer="false" > </listview> <button android:id="@+id/button_ing" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="" android:background="@drawable/add_recipe_button" android:onclick="additems"/> </linearlayout> </scrollview></linearlayout> old oncreate() function code:
protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.add_recipe_form); spinner = (spinner)myhead.findviewbyid(r.id.category_spinner); cursor cursor = mydb.getcategorieslist(); arraylist<category> list = new arraylist<category>(); list.add(new category(0,"choose category")); while (cursor.movetonext()) { list.add(new category(cursor.getint(0),cursor.getstring(1))); } // step 2: create , fill arrayadapter bunch of "state" objects arrayadapter spinnerarrayadapter = new arrayadapter(this,android.r.layout.simple_spinner_item, list); // step 3: tell spinner our adapter spinner.setadapter(spinnerarrayadapter); spinner.setonitemselectedlistener(this); setlistadapter(adapter); ingredients.add((view)findviewbyid(r.layout.row_add_recipe)); adapter.notifydatasetchanged(); } if move code related fill spinner database data, returns me nullpointerexception it's not found in layout. need keep here , solution adding addheaderview() listview seems ok, have nullpointerexception regarding head layout:
protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.add_recipe_form); listview mylistview = (listview) findviewbyid(android.r.id.list); linearlayout myhead = (linearlayout)findviewbyid(r.id.linear_form); mylistview.addheaderview(myhead); spinner = (spinner)myhead.findviewbyid(r.id.category_spinner); cursor cursor = mydb.getcategorieslist(); arraylist<category> list = new arraylist<category>(); list.add(new category(0,"choose category")); while (cursor.movetonext()) { list.add(new category(cursor.getint(0),cursor.getstring(1))); } // step 2: create , fill arrayadapter bunch of "state" objects arrayadapter spinnerarrayadapter = new arrayadapter(this,android.r.layout.simple_spinner_item, list); // step 3: tell spinner our adapter spinner.setadapter(spinnerarrayadapter); spinner.setonitemselectedlistener(this); setlistadapter(adapter); ingredients.add((view)findviewbyid(r.layout.row_add_recipe)); adapter.notifydatasetchanged(); }
if understand well, need more views wich scrollable along listview. best way implement call addheaderview() , addfooterview() on listview().
edit:
it should go this, think:
@override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.your_main_layout); layoutinflater inflater = (layoutinflater)getsystemservice(context.layout_inflater_service); view header = inflater.inflate(r.layout.your_header_layout); //r.layout, not r.id! (listview) list = findviewbyid(android.r.list); list.addheaderview(header); list.setadapter(adapter); //according docs should call setadapter() after addheaderview() //to spinner (spinner) spinner = (spinner) header.findviewbyid(r.id.spinner); } i'm writing memory , didn't test it, think should work. try out when moment.
