You know if I set up a ViewFlipper in layout, it always start from the first item to bottom.
But is there a way to start from the 2nd or 3rd item of ViewFlipper on "onCreate"?
Let's say if counter == 2, the page will display <-- 2 --> item onCreate.
This is my onCreate and flipper.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playlist);}
xml
<ViewFlipper
android:id="#+id/flipper"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:inAnimation="#anim/flipin"
android:outAnimation="#anim/flipout" >
<!-- 1 -->
<LinearLayout
android:id="#+id/one"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/airongbg"/>
</LinearLayout>
<!-- 2 -->
<LinearLayout
android:id="#+id/two"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/hopefalls"/>
</LinearLayout>
<!-- 3 -->
<LinearLayout
android:id="#+id/three"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/moon"/>
</LinearLayout>
Use this
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playlist);
((ViewFlipper) this.findViewById(R.id.flipper)).setDisplayedChild(1); //1 for 2 Since it accept Ordinal number
}
First Get the position of the item which you want to show by
int id ;
id=flipper.indexOfChild(ImageView1);
// then call the itm as
flipper.setDisplayedChild(id);
you will be able to set the desired item

I have the following main.axml file
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/refresher"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:minWidth="25px"
android:minHeight="25px"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:choiceMode="singleChoice"
android:id="#+id/myListView" />
<RelativeLayout

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center">

I require the ability to swipe down on my listview to refresh and also I require a "spinning circle loading animated icon" on initial load. However
if the Listview is above the relative layout as shown i do not get the spinning circle on initial load, but do get my Listview/refresh.
But if i change the RelativeLayout to be above the Listview i get the spinning circle on load but my Listview is not shown after?
In my onCreate method on the acitivity.
protected async override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
// Find view components
blogListView = FindViewById<ListView>(Resource.Id.myListView);
listViewRefresher = FindViewById<SwipeRefreshLayout>(Resource.Id.refresher);
loadingPanel = FindViewById<RelativeLayout>(Resource.Id.loadingPanel);
blogListView.Adapter = new FeedAdapter(this, _blogPosts);
//Register events
listViewRefresher.Refresh += HandleRefresh;
blogListView.ItemClick += OnListItemClick;
// Populate views
await PoplulateBlogPostsFromExternalWebUrl();
loadingPanel.Visibility = ViewStates.Gone;
}
According to the android docs SwipeRefreshLayout can only host one child. As a result the second view is always being hidden. To get this to work you will have to wrap the ListView and RelativeLayout in another RelativeLayout. It's also worth noting that the RelativeLayout wrapping the ProgressBar can probably be removed if an id is put on the ProgressBar.
The OP discovered (in the comments above) that this caused the SwipeRefreshLayout to be triggered when the list was scrolled up. To address this you would need to disable the layout when the list view is not at the top.
Sample Code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/refresher"
android:layout_width="fill_parent"

<RelativeLayout
android:id="#+id/loadingContainer"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

android:minHeight="25px"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<RelativeLayout
android:id="#+id/loadingPanel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

I created a menuView.xml layout to be in all of the layouts of my activity. This layout has one column on each border and a title bar like this:
ComposeView http://img845.imageshack.us/img845/2121/d6zp.png
I insert this layout in the other layouts this way:
<!-- Show menu -->
<com.example.MenuView
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
But if one of the layouts has full screen view, part of this view gets covered by the MenuView, so...
How could I tell to this view to adapt its size to the blank space inside the MenuView to not get covered by it?
UPDATE -- full XML included
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:background="#drawable/degradado">
<!-- Show menu -->
<com.example.MenuView
android:layout_width="match_parent"
android:layout_height="match_parent" />
<RelativeLayout
android:id="#+id/Left_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentBottom="true" >
//Here go buttons, views, etc...
</RelativeLayout>
<RelativeLayout
android:id="#+id/Right_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true" >
//Here go buttons, views, etc...
</RelativeLayout>
What happens here is that these 2 Relative layouts get covered by the MenuView (The darkest gre borders and the top black bar), and the ideal way would be that these 2 layouts get fitted to the blank space (the clearest gray).
I can solve this setting margin sizes to the Relative layouts to fit inside of it, but i know this is not the best way to do it, so I don't know if there is another way.
I think the best way to solve your issue is with inheritance.
If you define an Activity that can be used as a template for all your fleshed out Activitys to add their content to.
I don't know what you custom menu is 'made of' but as a simple example:
Create a basic Activity with code:
public class ActivityWithMenu extends Activity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_with_menu_layout);
}
}
and xml:
<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"
tools:context=".ActivityWithMenu" >
<TextView
android:layout_width="match_parent"
android:layout_height="20dip"
android:background="#ff000000"
android:textColor="#ffffffff"
android:text="Main Menu Title Bar"
android:id="#+id/mainmenutitle" />
<LinearLayout
android:layout_width="20dip"
android:layout_height="match_parent"
android:layout_below="#+id/mainmenutitle"
android:layout_alignParentLeft="true"
android:background="#ff999999"
android:orientation="vertical"
android:id="#+id/lefthandmenu" />
<LinearLayout
android:layout_width="20dip"
android:layout_height="match_parent"
android:layout_below="#+id/mainmenutitle"
android:layout_alignParentRight="true"
android:background="#ff999999"
android:orientation="vertical"
android:id="#+id/righthandmenu" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_toLeftOf="#+id/righthandmenu"
android:layout_toRightOf="#+id/lefthandmenu"
android:layout_below="#+id/mainmenutitle"
android:orientation="vertical"
android:id="#+id/activitycontent"
/>
</RelativeLayout>
Then create your xml for a specific Activity, in this case a simple 'Hello World' layout:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff00ff00"
android:text="Hello World!"
/>
</LinearLayout>
</ScrollView>
But now when you write the code for this Activity, extend 'ActivityWithMenu' instead of the Activity class direct and inflate this xml layout as follows:
public class Activity1 extends ActivityWithMenu
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
LinearLayout ll = (LinearLayout)findViewById(R.id.activitycontent);
ScrollView sv = (ScrollView)this.getLayoutInflater().inflate(R.layout.activity1_layout, ll, false);
ll.addView(sv);
}
}
I have added the code for making the Activity fullscreen here instead of in the parent ActivityWithMenu class assuming that you wouldn't want them all displayed that way but you could move it into the parent class if appropriate.
Hope this helps.
I'm trying to add a header to my listView but I see only black screen when activity launches
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.maincoverflow);
final ListView itemslist = (ListView)findViewById(R.id.itemslist);
LayoutInflater inflater = getLayoutInflater();
ViewGroup mTop = (ViewGroup)inflater.inflate(R.layout.main_header, itemslist, false);
itemslist.addHeaderView(mTop, null, false);
//some actions with header and list items
//example: coverflow_item_title is located in header(R.layout.main_header)
title = (TextView)findViewById(R.id.coverflow_item_title); //checked - is not null
CoverFlow coverFlow = (CoverFlow) findViewById(R.id.coverflow);
ImageAdapter coverImageAdapter = new ImageAdapter(this);
coverFlow.setAdapter(new ImageAdapter(this));
coverImageAdapter.createImages();
coverFlow.setAdapter(coverImageAdapter);
coverFlow.setOnItemSelectedListener(new CoverAdapterView.OnItemSelectedListener(){
...
adapter = new LazyAdapter(MainCoverflowActivity.this, tools, tools_images);
itemslist.setAdapter(adapter);
}
itemslist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
...
}
}
maincoverflow.xml:
<?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:orientation="vertical" >
<ListView
android:id="#+id/itemslist"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
</LinearLayout>
main_header.xml:
<?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" >
<TextView
android:id="#+id/coverflow_item_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium" />
<com.thumbsupstudio.mobitour.CoverFlow
android:id="#+id/coverflow"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<ImageView
android:id="#+id/shadowbox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="#drawable/shadow_box" />
</LinearLayout>
You may notice that I'm using Coverflow widget (from here http://www.inter-fuser.com/2010/01/android-coverflow-widget.html) - it works fine.
In general, I'm changing listView content when Coverflow item is changed. It works fine, but I need Coverflow to scroll with listView, so I decided to attach it to header. After that, there's no listView and Coverflow on the screen, everything is black.
try this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/headerLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"/>
<TextView
android:id="#+id/coverflow_item_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium" />
<com.thumbsupstudio.mobitour.CoverFlow
android:id="#+id/coverflow"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<ImageView
android:id="#+id/shadowbox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="#drawable/shadow_box" />
</RelativeLayout>
<ListView
android:id="#+id/itemslist"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
</RelativeLayout>
I found a solution. I don't fully understand WHY but:
NOT CORRECT
init listView
inflate header and add it to the list
set list adapter in Coverflow onItemSelected handler (it launch automatically with item position=0)
CORRECT
init listView
inflate header and add it to the list
set any adapter to listView (!!!)
set listView adapter in Coverflow onItemSelected handler (it launch automatically with item position=0)
after activity launches listView has adapter content which was set in Coverflow onItemSelected handler. What for is first adapter assignment - I don't understand.
I have to setup the background image for listview.Not setting image for each row.have to setup the background image for whole screen & select the radio button when list view load. that means first option should be selected
This is my code.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sales_routes); // **Added edited**
ArrayList<Object> routeList = getWmRoute();
ArrayList<String> routhPath = new ArrayList<String>();
for(int i = 0; i<routeList.size();i++){
routhPath.add(((WMRoute) routeList.get(i)).getDescription());
}
this.setListAdapter(new ArrayAdapter<String>(this, R.layout.list_two_column, R.id.FROM_CELL, routhPath));
ListView list=getListView();
}
and my xml file is (list_two_column.xml)
<?xml version="1.0" encoding="utf-8"?>
<!-- row.xml -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:paddingTop="4dip"
android:paddingBottom="6dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<!--android:background="#drawable/wallpaper" -->
<RadioButton android:id="#+id/radioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</RadioButton>
<TextView android:id="#+id/FROM_CELL"
android:layout_width="70dip"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
Added Newly - sales_routes.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#android:id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="6dip"
android:layout_marginRight="6dip"
android:dividerHeight="2dip"
android:background="#drawable/wallpaper" />
</LinearLayout>
currently its display list, the problem is image background image
Requirement
select the radio button when listview load. that means first option should select
make a style theme in values folder and add a windowBackground item to it and add that style to your layout xml
I am switching activities on tab clicks and successful at this. But, in one of my Activity class I am doing the following:
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
main.xml has the following:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#BDBDBD">
</LinearLayout>
I want to change the background of this layout only and I want tabs to their as it is. But with the current android:layout_height="fill_parent" in main.xml my background is overwriting the tabs which means I am unable to see tabs. and If I make android:layout_height="wrap_content" I cannot see any change taking and tabs are still their.
Please help.

screen2.xml has a scrollview and iside that I have a linearlayout which has a login form...but this form whenever is called just comes above the tabs...please help
You are doing something wrong with your tabs. Are you just launching a new activity when the tab is clicked? Then, if that new activitys layout covers the entire screen, ofcourse the tabs will be covered by this.
