I have a ListView and a button in my view. Button is placed just below the listview. My listview contains 10 items. When I am running the application. I can't see the button inside the view. Because of 10 items i have to scroll the listview to see all items. If i use 4 items, I can see the button. Why it is happened?
Please help me.
Thank you..
I think you want button to be displayed always on the screen whatever maybe the size of the screen/list.
Just make your layouts to be AbsoluteLayouts as below
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Pixels"
android:layout_y="50px"
android:layout_x="80px"
android:focusable="true">
</Button>
<ListView android:id="#+id/ListView01"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
</ListView>
</AbsoluteLayout>
& in you UI thread use bringToFront on that button as below
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
Button b= (Button) findViewById(R.id.button);
b.setText("Button");
b.bringToFront();
....
}
and you are done!
Sounds like you might not use layout correctly. Are you using a linear layout in the view? If so you might want to look at relative layout. Align your button to parentBottom and make you list align to parentTop and to above your button. That should make the list scroll and not expand.
check the width of your views, make sure it is set to wrap_contnet
You can modify your xml like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="1">
<ListView android:layout_width="match_parent"
android:id="#+id/listVie"
android:layout_weight="0.80"
android:layout_height="0dp">
</ListView>
<Button
android:layout_width="fill_parent"
android:layout_weight="0.20"
android:layout_height="0dp"/>
</LinearLayout>
Look at the weight property:
android:weightSum="1"
android:layout_weight="0.80"
android:layout_weight="0.20"
They are making it :)
You shold use
android:weightSum="10"
android:layout_weight="8"
android:layout_weight="2"
I have a ListView and a button in my view. Button is placed just below the listview. My listview contains 10 items. When I am running the application. I can't see the button inside the view.
You can use relative layout something like this to achieve
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#00000000">
<ListView
android:id="#+id/frg_product_inq_productSp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/btn_add"
android:layout_alignParentTop="true"
android:divider="#ffffff"
android:dividerHeight="0.5dp"
android:gravity="center" />
<Button
android:id="#+id/btn_add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_gravity="center"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:text="ADD"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
And i.e your output will look like below for all devices

How can i create the layout like i attached in the background as normal any layout.From that layout when i click any or get back to that layout, the overlay layout should come with any form fields buttons or text ...any
Thanks in advance.
Use RelativeLayout or FrameLayout. The last child view will overlay everything else.
To be sure the overlay view is on top, you can call ViewGroup.bringChildViewToFront() on the relative layout.
Example:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/root_view">
<EditText
android:layout_width="fill_parent"
android:id="#+id/editText1"
android:layout_height="fill_parent">
</EditText>
<EditText
android:layout_width="fill_parent"
android:id="#+id/editText2"
android:layout_height="fill_parent">
<requestFocus></requestFocus>
</EditText>
</FrameLayout>
In this layout, editText2 will cover the editText1
I believe you should use FrameLayout, you can add objects one in front of the other. Please read about it at documentation.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/root_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- other actual layout stuff here -->
</LinearLayout>
<LinearLayout
android:id="#+id/overlay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right" >
</LinearLayout>
</FrameLayout>
Now any view you add under LinearLayout with android:id = "#+id/overlay"
will appear as overlay with gravity = right
hopefully this will help you
I have a scrollable ListView with items (like in http://developer.android.com/resources/tutorials/views/hello-listview.html). I am using an ArrayAdapter for the items and use it as a parameter in setListAdapter. Now I would like to add a button at the bottom of the screen, which does not scroll with the list. Could someone give me some hints or post a code snippet how it could possibly be done?
If your activity extends ListActivity then you need something like this:
<LinearLayout android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView android:id="#android:id/list"
android:layout_height="0dip"
android:layout_width="match_parent"
android:layout_weight="1" />
<Button android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
Notice that the listview has a layout_weight set to 1. That will keep the button fixed in its place at the bottom.
you can use a RelativeLayout to fix the button at the bottom of your layout , and add your listView above it like this :
<RelativeLayout android:layout_width="match_parent"
android:layout_height="match_parent">
<Button android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"/>
<ListView
android:id="#android:id/list"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_above="#id/btn" />
</RelativeLayout>
My solution based on Houcline's solution but ListView always above Button
<CheckBox
android:id="#+id/chbRemoveIfUninstall"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"/>
<ListView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_above="#id/chbRemoveIfUninstall"/>
I have the following android layout that displays toe list views in the screen one in left side one the other to right side.
<?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="horizontal">
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="1" android:id="#+id/ListView01"/>
<ListView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="3" android:id="#+id/ListView02"/>
Now I want to add a button displayed it the bottom right side of the screen.
Can anyone help me about how I could do that?
first remove the linear layout,use relative layout.for button use the following command
android:layout_alignParentBottom="true" and android:layout_alignParentRight="true"
A possible solution should be: Add a RelativeLayout as root layout and put the button after the LinearLayout with properties layout_below and layout_right (LinearLayout as reference).
Try to use the following code
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:background="#ffffff"
>
<Button
android:id="#+id/click"
android:layout_width="100dip"
android:layout_height="60dip"
android:text="Click"
android:layout_alignParentRight="true"
/>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ListView02"
android:background="#00ff00"
android:layout_toLeftOf="#+id/click"
/>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ListView01"
android:background="#000000"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/ListView02"
/>
</RelativeLayout>

I want to have a button at the bottom of the listview.
If I use relativeLayout/FrameLayout, it aligns but listView goes down to very botton.
(Behind the button at the bottom)
FrameLayout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
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="#+id/listview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/btnButton"
android:text="Hello"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
</FrameLayout>
</FrameLayout>
RelativeLayout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
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="#+id/listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/btnButton"
android:text="Hello"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
</RelativeLayout>
</RelativeLayout>
Above two codes only work like the first image. What I want is second image.
Can anybody help?
Thank you.
A FrameLayouts purpose is to overlay things on top of each other. This is not what you want.
In your RelativeLayout example you set the ListViews height and width to MATCH_PARENT this is going to make it take up the same amount of space as its parent, and thus take up all of the space on the page (and covers the button).
Try something like:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"/>
</LinearLayout>
The layout_weight dictates how the extra space is to be used. The Button does not want to stretch beyond the space it requires, so it has a weight of 0. The ListView wants to take up all of the extra space, so it has a weight of 1.
You could accomplish something similar using a RelativeLayout, but if it is just these two items then I think a LinearLayout is simpler.
<?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"
android:background="#ffffff"
>
<ListView android:id="#+id/ListView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1">
</ListView>
<FrameLayout android:id="#+id/FrameLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button android:id="#+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="button"
android:layout_gravity="center_horizontal">
</Button>
</FrameLayout>
</LinearLayout>
Here is the design you are looking for.
Try it.
I needed two buttons side-by-side at the bottom. I used a horizontal linear layout, but assigning android:layout_height="0dp" and android:layout_weight="0" for the buttons' linear layout didn't work. Assigning android:layout_height="wrap_content" for just the buttons' linear layout did. Here's my working layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/new_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="New" />
<Button
android:id="#+id/suggest_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Suggest" />
</LinearLayout>
</LinearLayout>
RelativeLayout will ignore its children android:layout_width or android:layout_height attributes, if the children have attributes that properly define their left and right or top and bottom values, respectively.
To achieve the result on the right image, showing the list above the button, your layout should look like this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#android:id/button1"
android:layout_alignParentTop="true"/>
<Button
android:id="#android:id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="#android:string/ok"/>
</RelativeLayout>
The key is to define android:layout_alignParentTop (defines top value) and android:layout_above (defines bottom value) in your RecyclerView. This way, RelativeLayout will ignore android:layout_height="match_parent", and the RecyclerView will be placed above the Button.
Also, make sure you look into android:layout_alignWithParentIfMissing, if you have a more complex layout and you still need to define these values.
I am using Xamarin Android, and my requirement is exactly the same as William T. Mallard, above, i.e. a ListView with 2 side-by-side buttons under it.
The solution is this answer didn't work in Xamarin Studio however - when I set the height of the ListView to "0dp", the ListView simply disappeared.
My working Xamarin Android code is as follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="#+id/ListView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_above="#+id/ButtonsLinearLayout" />
<LinearLayout
android:id="#id/ButtonsLinearLayout"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="horizontal"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/Button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" />
<Button
android:id="#+id/Button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
</RelativeLayout>
I aligned ButtonsLinearLayout to the bottom of the screen, and set the ListView to be above ButtonsLinearLayout.
#jclova one more thing you can do is use layout-below=#+id/listviewid in relative layout
In your relative layout height of listview is match_parent which is fill_parent(for 2.1 and older) so best solution is if you want to use relative layout then first Declare your button then your list view, make list view position as above your button id, If you want button always at bottom then make it alignParentBottom..
Snippet is
<RelativeLayout
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:id="#+id/rl1"><Button
android:layout_width="MATCH_PARENT"
android:layout_height="WRAP_CONTENT"
/><ListView
android:layout_width="MATCH_PARENT"
android:layout_height="0"
android:layout_above="#id/listview"/></RelativeLayout>
This prevents your list view taking whole place and make your button appear..
This will be the best and the most simple solution to the problem. Just add android:layout_above="#id/nameOfId" in the layout that you want to move above with respect to that layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.sumeru.commons.activity.CommonDocumentUploadActivity">
<ListView
android:id="#+id/documentList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#id/verifyOtp" />
<com.sumeru.commons.helper.CustomButton
android:id="#+id/verifyOtp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="#string/otp_verification" />
</RelativeLayout>
I have a listactivity with the following layout-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"
xmlns:myapp="http://schemas.android.com/apk/res/se.javalia.myDrinks"
>
<Button android:id="#+id/saveButton"
android:text="test test"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/android:list"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/android:empty"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/main_no_items" />
</LinearLayout>
Now, I'd like to add a button above the list that stays in place when the list is scrolled.
Is it possible at all?
Thanks in advance
Roland
It's definitely possible, just add a Button before the ListView in your XML. If your View becomes more involved, I would change your LinearLayout to be a RelativeLayout, and then you can position the elements more easily.
Yes, just add a button above the ListView.
In your 1st LinearLayout you should add: android:orientation="vertical"
