I'm trying to replicate a spinner control (please don't ask why) I'm struggling with the divider. The fake spinner looks fine until I add the divider to the left of the imageview. Once I add the divider it's height fills the remaining portion of the screen. Can someone please explain this?
The following xml:
.......
<Spinner
android:id="#+id/equipment_spinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
<ImageView
android:id="#+id/spinner_arrow"
android:layout_width="45sp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="#drawable/spinner_arrow"/>
</RelativeLayout>
</LinearLayout>
</ScrollView>
produces the following screen:
once I add the divider, the xml looks like this:
<Spinner
android:id="#+id/equipment_spinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
<ImageView
android:id="#+id/spinner_arrow"
android:layout_width="45sp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="#drawable/spinner_arrow"/>
<View
android:background="#e7ebe7"
android:layout_width="1dip"
android:layout_height="fill_parent"
android:layout_toLeftOf="#id/spinner_arrow"/>
</RelativeLayout>
</LinearLayout>
</ScrollView>
which produces the following screen:
can anyone spot what i'm doing wrong here?...
You should use a nine-patch image for this instead of using multiple views. That's what the default Spinner does. I don't know why you want to create a new spinner, but if you're keeping the visuals the same you can just reuse the built-in images.
android.R.layout.simple_spinner_item is a TextView layout you could reuse. Or, you can just take the background directly: android.R.drawable.btn_dropdown, which is an XML selector drawable with bitmaps for each state. More details are available in the Android source code.
You have the height set to fill parent which fills the remainder of the Relative Layout. Have you tried putting the View inside the button or imageview as follows:
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true">
<View
android:background="#e7ebe7"
android:layout_width="1dip"
android:layout_height="fill_parent"
android:layout_toLeftOf="#id/spinner_arrow"/>
</Button>
<ImageView
android:id="#+id/spinner_arrow"
android:layout_width="45sp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="#drawable/spinner_arrow"/>
</RelativeLayout>
OR
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
<ImageView
android:id="#+id/spinner_arrow"
android:layout_width="45sp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="#drawable/spinner_arrow">
<View
android:background="#e7ebe7"
android:layout_width="1dip"
android:layout_height="fill_parent"
android:layout_toLeftOf="#id/spinner_arrow"/>
</ImageView>
</RelativeLayout>
If this doesnt work try setting the height of the relative layout to a fixed amount like 10 dip or however big that spinner is... you may have to try a fiew different sized, just dont leave the relativelayout as wrap content

I have a horizontal list of images in my android application. But the problem is some of the images seems to not follow the layout I've defined in my xml. Like this:
my layouts look like this:
mainlayout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/back_shop_list"
android:orientation="horizontal">
<com.devsmart.android.ui.HorizontalListView
android:id="#+id/shop_hlist_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:scrollX="1dp"
android:scrollY="1dp"
android:overScrollMode="always" >
</com.devsmart.android.ui.HorizontalListView>
</LinearLayout>
then my listlayout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:translationY="200dp" >

My guess is that the size of my image is lesser than what my ImageView layout_width and height. Or I dont really know what causes this problem.
But any help will do, please. Thanks.
EDIT: What I really wanted is that if the image is like image 4 and image 5, it should not have those spaces. I've tried getting the size of the image from my ImageLoader then set the layout parameters height and width in there while images are loaded. But it looked worse.
Are there other ways in which i can dynamically adjust my ImageView if ever the images are like image 4 and 5?
If actually you want to make the image occupy the desired space
try adding this image View property to your ImageView
You can try others I usually use fitXY out of the predefined list you will get there in XML Layout
android:scaleType="fitXY"
so as to make this property work we also need
android:adjustViewBounds="true"
that you have already added in your case
If actually you want to avoid on blank spaces and let the image occupy as much space as it want
In my layout I am using two image views to show a demo
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ll_numbers"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignLeft="#+id/tv_numbers"
android:layout_below="#+id/tv_numbers"
android:layout_marginTop="5dip"
android:layout_marginRight="10dip"
android:orientation="vertical">
<ImageView
android:id="#+id/textView1"
android:layout_width="200dip"
android:layout_height="200dip"
android:src="#drawable/desert"/>
<ImageView
android:id="#+id/textView2"
android:layout_width="200dip"
android:layout_height="200dip"
android:background="#drawable/desert"/>
</LinearLayout>
ImageView 1 is assigning image as Source using android:src="#drawable/desert"
and below is the result as you can notice that it is showing WhiteSpace arround it.
ImageView2 is assigning image as Background using android:background="#drawable/desert"
and below is the result as you can notice that it is showing no WhiteSpace arround it.
Or try using these attributes to make it possible
android:maxHeight=""
android:maxWidth=""
android:minHeight=""
android:minWidth=""
I have a relative layout, and inside it i place 3 items, 2 imageviews and one scrollview.
My layout is like this...

The above code produces the view shown here:
You may note that the arrows are not aligned in the center, but are slightly moved to the right. Why is that, and how can I fix it ? Note that i have already used android:layout_centerHorizontal="true" to my imageviews.
Thank you in advance
Its problem with your
android:layout_margin="8dp"
remove it from both scrollview and imageView
and pass it to RelativeLayout direct.
or add
android:layout_marginTop="8dip"
android:layout_marginBottom="8dip"
in your RelativeLayout.
and pass
android:layout_centerHorizontal="true"
to your scrollview
they are aligned to the center if you put the marginRight into consideration, try adding android:layout_margin="8dp" to the arrows.
u need to set image view that is under the Relative layout set this image view width fill parent.
Try removing android:layout_weight="1" from your RelativeLayout and see if it works.
In your LinearLayout, the attribute android:orientation="horizontal" causing your display to be aligned horizontaly. Therefore your RelativeLayout is in center but since its shared with another layout thats why you cant note the difference. If you completely remove the first RelativeLayout (the one with id logosLayout) then i hope you'll see the second layout in center.
So, first you need to define the hierarchy of layout you require and then adjust your views accordingly.
It seems problem with your android:layout_margin="8dp" for your scrollview only and pass it to RelativeLayout direct but instead of using margin use padding = "8dp".
I wish to keep a button at the bottom of my Activity screen. It has to be fixed irrespective of the size of scrollview above it. The problem is that once the textviews of the scrollview take up some place, the height of my button keeps decreasing and it eventually gets pushed out of the activity screen. This is the layout I am using.
<?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:textSize="20sp" />
<TextView android:id="#+id/tvURL" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_marginBottom="30dp"
android:paddingTop="10dp" android:layout_gravity="center"
android:text="hello" android:textColor="#android:color/white"
android:typeface="sans" />
</LinearLayout>
</ScrollView>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:gravity="bottom">
<Button android:id="#+id/btBottom" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="1"
android:text="Enter" />
</RelativeLayout>
</LinearLayout>
I have also tried using android:weight=1 and android:layout_height=0dp in the Scrollview. But this removes the entire Scrollview portion from my activity and I can't see anything.
I do know that there are many similar questions asked about this and believe me, I have tried many of these. However, none of the tricks have worked for me. I have spent almost half a day fixing this. Kindly help.
For a case like this always use RelativeLayouts. A LinearLayout is not intended for such a usage.
Try this:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true">
<Button android:id="#+id/btBottom"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Enter"
android:layout_alignParentBottom="true"/>
<ScrollView
...
android:layout_above="#id/btnGetMoreResults"/>
</RelativeLayour>
You should try using RealativeLayout instead of Linear, and then you could use
android:layout_above="#+id/btBottom"
android:layout_alignParentBottom="true"
That should solve your problem.
looks like you need 'alignParentBottom' in your button like this
<Button android:id="#+id/btBottom"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Enter" />
Do not wrap Button to RelativeLayout
Set layout_height of ScrollView to 0dp
Add layout_weight of ScrollView to 1
For this it would probably be a good idea if you used RelativeLayout for the outer wrapper layout. Then you could just set the layout with the button inside to LinearLayout and set layout_alignParentButtom="true" while you set your #+id/Scroll to layout_alignParentTop="true"
Also, you should probably set the layout with the button inside´s height to wrap_content instead of fill_parent
Why do you use a LinearLayout at top level at all ?
Choose a RelativeLayout with fill/fill and the following three childern (no further nesting !):
1) TextView with android:layout_alignParentTop="true" and android:layout_centerHorizontal="true"
2) Button with android:layout_alignParentBottom="true" and android:layout_centerHorizontal="true"
3) ScrollView with android:layout_below=#id/textview_id and android:layout_above="#id/button_id"
I didn't test it though, but give it a try.
I have the following layout for a custom title bar. However, the problem is this: both the imageview and the imagebutton are coming at the centre. I was expecting the imagebutton to be at the extreme right. Can anyone kindly let me know what I did wrong here ? Thanks.

Your layout is only 35dip tall, so pressumibly if you show your ImageView the ImageButton gets positioned outside the screen. Consider changing your layout_height to wrap_content, if appropiate.
You're using a vertically oriented LinearLayout, all View will be presented in a vertical fashion. Use a RelativeLayout so that you'll have more control over where Views are positioned. If you'd still like to use a LinearLayout, you'll have to use horizontal orientation so that the Views can be on the same "line".
Use layout_gravity to layout the item to the right, just gravity is used by the contents of the view.
At first if width is set to fill parent it really fills parent so it use all the width.
Second: why not RelativeLayout? It provides more options and control.
Maybe this is what you looking for:

Hy!
I have two pictures on the view and a button at the buttom.
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content" android:layout_width="fill_parent" android:orientation="vertical">
<TextView android:layout_height="wrap_content" android:id="#+id/mainscreen" android:layout_width="fill_parent" android:text="Selected Channel" android:gravity="center" android:layout_alignParentTop="true"></TextView>
<ImageView android:id="#+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView>
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="#+id/mainscreen_state" android:layout_above="#+id/mainscreen_btchange"></TextView>
<ImageView android:layout_width="wrap_content" android:layout_centerHorizontal="true" android:layout_height="wrap_content" android:id="#+id/ImageAd" android:layout_gravity="center" android:layout_below="#+id/mainscreen"></ImageView> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:id="#+id/mainscreen_btchange"
android:text="Change State"></Button>
</RelativeLayout>
</LinearLayout>
My Question: How to shrink the pictures that all elements of the layout are shown?
For more complicated layouts where I need to ensure a bunch of items can all be displayed, I usually start with a RelativeLayout as my outermost container. I dock whatever needs to be at the extremities with layout_alignParentTop and layout_alignParentBottom (in the case of vertical layouts, which yours seems to be), and then I work my in making the next set of elements relative to them. Basically, start at the edges and work your way in.
So, in your case, the Button should have the attribute android:layout_alignParentBottom="true", and the TV should have android:layout_above="#+id/mainscreen_btchange". The TextView at the top should have android:layout_alignParentTop="true" and the ImageView underneath it should have android:layout_below="#+id/mainscreen"
