Android Layout question? - android

I want to have navigation bar at the bottom of my screen.
There will be 'Prev' button at rightest and a 'Next' button at leftest.
And a textview on center.
I tried linear and relative layout but failed.
When I put width="fill_parent" to text then left button dissappears.
Here the one I tried:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:id="#+id/rlayout"
android:layout_height="fill_parent"
>
<!-- other content a listview etc.
-->
<LinearLayout android:id="#+id/navigator"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<Button android:id="#+id/prevbtn"
android:background="#drawable/prev" android:onClick="prevPage"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/pageText"
android:text=""
android:gravity="center_horizontal"
android:layout_centerHorizontal="true"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<Button android:id="#+id/nextbtn"
android:background="#drawable/next"
android:onClick="nextPage"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</RelativeLayout>


The following code changes will work:
For the textview change 'fill_parent' to 'wrap_content for both height and width.
For the buttons and the textview add android:layout_weight="1".
<LinearLayout
android:id="#+id/navigator"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/prevbtn"
android:onClick="prevPage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<TextView
android:id="#+id/pageText"
android:text=""
android:gravity="center_horizontal"
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" />
<Button
android:id="#+id/nextbtn"
android:onClick="nextPage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>


Try alignParentLeft="true" and alignParentRight="true" on the two buttons.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:id="#+id/rlayout"
android:layout_height="fill_parent"
>
<!-- other content a listview etc.
-->
<LinearLayout android:id="#+id/navigator"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<Button android:id="#+id/prevbtn"
android:background="#drawable/prev"
android:onClick="prevPage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:alignParentLeft="true" />
<TextView
android:id="#+id/pageText"
android:text=""
android:gravity="center_horizontal"
android:layout_centerHorizontal="true"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<Button android:id="#+id/nextbtn"
android:background="#drawable/next"
android:onClick="nextPage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:alignParentRight="true" />
</LinearLayout>
</RelativeLayout>

Android scrollview not resizing the way I expected

I'm using a layout for a configuration panel comprising a LinearLayout (vertical) containing two sub-views: a main subview that's a ScrollView (it has lots of stuff in it - more than fits on the screen, so I'm using the ScrollView to deal with that) and a panel that appears when something in the configuration panel changes (with the usual things: a button to save and a button to revert). The problem is that I can't convince the ScrollView to shrink to allow the "save/revert" panel any space on the screen.
Here's an excerpt of the layout file: [EDIT: added contents of ScrollView]

When I make the #id/save layout visible (using setVisibility(View.VISIBLE)) it doesn't cause that ScrollView to resize. Any thoughts on why that is and what I should do about it?
I have 2 options: a) fix the size of the scrollview so that it always leaves room for the panel, or b) get rid of the panel and just pop up a dialog when the back button is pressed. I like the second one better mostly because I already have that working.

There is no content within the scrollview.Please add contents

//Place your layouts and contents here for things to get scroll

how to align text vertically center in android

I have arabic text, therefore I set gravity to right in order to start text from right side. Text starts from right now. But another issue is text starts to render from the top of the page. But I need to vertically center the text.
Although I tried several variations I couldnt make it vertically center.
Here is the sample of my xml file.
<LinearLayout
android:id="#+id/linearLayout5"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:orientation="vertical" >
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginBottom="23dp"
android:gravity="right"
android:padding="#dimen/padding_maintextview"
android:text="#string/text"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="20sp" />
</LinearLayout>
Problem is with above textview.
Here I have put whole xml file.
<?xml version="1.0" encoding="utf-8"?>

But I am in same situation. No text is vertically centered

Your TextView Attributes need to be something like,
<TextView ...
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical|right" ../>
Now, Description why these need to be done,
android:layout_width="match_parent"
android:layout_height="match_parent"
Makes your TextView to match_parent or fill_parent if You don't want to be it like, match_parent you have to give some specified values to layout_height so it get space for vertical center gravity. android:layout_width="match_parent" necessary because it align your TextView in Right side so you can recognize respect to Parent Layout of TextView.
Now, its about android:gravity which makes the content of Your TextView alignment. android:layout_gravity makes alignment of TextView respected to its Parent Layout.
Update:
As below comment says use fill_parent instead of match_parent. (Problem in some device.)

The problem is the padding of the font on the textview. Just add to your textview:
android:includeFontPadding="false"

just use like this to make anything to center
android:layout_gravity="center"
android:gravity="center"
updated :
android:layout_gravity="center|right"
android:gravity="center|right"
Updated : Just remove MarginBottom from your textview.. Do like this.. for your textView
<LinearLayout
android:id="#+id/linearLayout5"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center" >
<TextView
android:id="#+id/textView2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center|right"
android:text="hello"
android:textSize="20dp" />
</LinearLayout>

Try to put android:gravity="center_vertical|right" inside parent LinearLayout else as you are inside RelativeLayout you can put android:layout_centerInParent="true" inside your scrollView.

In relative layout you need specify textview height:
android:layout_height="100dp"
Or specify lines attribute:
android:lines="3"

both textview show value on same location how do i change or space inbetween them?

in my barcode xml result file both text view show result on samre location and overlap each other how do i make space in between them?? i try android_layout gravity=center or left rightr is not work only this work android:layout_gravity="center_horizontal"
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<SurfaceView android:id="#+id/preview_view"
android:layout_width="fill_parent"
android:layout_gravity="center"
android:layout_height="fill_parent"
android:layout_centerInParent="true"/>
<com.zijunlin.Zxing.Demo.view.ViewfinderView
android:id="#+id/viewfinder_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/transparent"/>
<TextView android:id="#+id/txtResult"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="hello"
android:textSize="14sp"/>
<TextView
android:id="#+id/txtResult2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="aaaa" />
<Button
android:id="#+id/button1"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="25dip"
android:layout_marginRight="30dip"
android:text="View Detail" />
</FrameLayout>

Put your 2 TextView and Button inside a LinearLayout with orientation vertical. And 1 more point, When using FrameLayout, don't forget to add the attribute layout_gravity in your code.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<SurfaceView android:id="#+id/preview_view"
android:layout_width="fill_parent"
android:layout_gravity="center"
android:layout_height="fill_parent"
android:layout_centerInParent="true"/>
<com.zijunlin.Zxing.Demo.view.ViewfinderView
android:id="#+id/viewfinder_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/transparent"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<TextView
android:id="#+id/txtResult"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:gravity="center"
android:text="hello"
android:textSize="14sp" />
<TextView
android:id="#+id/txtResult2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:gravity="center"
android:text="aaaa" />
</LinearLayout>
<Button
android:id="#+id/button1"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="25dip"
android:layout_marginRight="30dip"
android:text="View Detail" />
</FrameLayout>
put the textview like the way above ....

Inherit ViewfinderView from RelativeLayout and use layout_toRightOf, layout_toLeftOf, layout_below or layout_above, whatever you need.
<com.zijunlin.Zxing.Demo.view.ViewfinderView
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<TextView android:id="#+id/txtResult"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="#+id/txtResult2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/txtResult"/>
</com.zijunlin.Zxing.Demo.view.ViewfinderView>

Android fix the image size

In my screen I am having 3 buttons and in next row below those buttons I am having 3 names (name corresponding to those buttons) but my problem is that when ever name changes then size of buttons also changes but I do want to fix the size of buttons here is my code please help me
<TableLayout android:background="#drawable/toptab"
android:layout_width="fill_parent" android:id="#+id/tableLayout"
android:layout_height="wrap_content"
android:stretchColumns="1" android:gravity="center_vertical"
android:layout_alignParentBottom="true">
<TableRow>
<ImageButton android:id="#+id/btnPrev" android:background="#drawable/imgPrev"
android:layout_marginLeft="5dp"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<ImageButton android:id="#+id/btnRefresh"
android:layout_gravity="center" android:background="#drawable/refreshbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ImageButton android:id="#+id/btnNext"
android:background="#drawable/imgNext"
android:layout_width="5dp"
android:layout_height="20dp"
android:layout_marginRight="5dp" />
</TableRow>
<TableRow >
<TextView android:id="#+id/prev" android:text="Hk" android:layout_marginLeft="5dp" />
<TextView android:id="#+id/refresh" android:text="Refresh" android:layout_gravity="center" />
<TextView android:id="#+id/next" android:text="RS" android:layout_marginRight="5dp" />
</TableRow>
</TableLayout>

If you want to avoid fixing button size, then I would recommend using different layout than TableLayout, maybe RelativeLayout and TextViews with property alignBaseline or LinearLayout with weight properties could do the trick.

You should use linearlayout instead of table layout and use Weight property for aligning buttons and text view in equal dimensions, so here if you write more text in text view , button size will not increase. Also you can add more buttons in same manner. Below is the XML file and screen shot.

Making linearlayouts stay at bottom of screen in android

I am making an android application that uses these views:
(Root) - LinearLayout
(Child of root) - ListView + 3 other linearlayouts beneeth that listview. But once i add to many items to the listview, the layouts are being placed outside of the screen. Which i don't want to. How can i make this happen? So that all of the three linearlayouts stay on the screen, at the bottom??? Please help and thanks in advance!
My screen XML code:
<?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:background="#drawable/background"
android:orientation="vertical" >
<TextView
android:id="#+id/NotesWelcomeTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/NotesWelcomeText" />
<ListView
android:id="#+android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</ListView
<LinearLayout
android:id="#+id/DeleteAllItemsFromListViewLinearLayout"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_weight="1"
android:visibility="invisible" >
<Button
android:id="#+id/CancelButton2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Cancel" />
<Button
android:id="#+id/DeleteAllButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Delete" />
</LinearLayout>
<LinearLayout
android:id="#+id/DeleteItemFromListViewLinearLayout"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_weight="1"
android:visibility="invisible" >
<Button
android:id="#+id/CancelButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Cancel" />
<Button
android:id="#+id/DeleteButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Delete" />
</LinearLayout>
<LinearLayout
android:id="#+id/AddItemToListViewLinearLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="gone" >
<EditText
android:id="#+id/AddItemToListViewEditText"
android:layout_width="250dp"
android:layout_height="wrap_content"
android:layout_weight="1" >
</EditText>
<Button
android:id="#+id/AddItemToListViewButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/Add" />
</LinearLayout>
</LinearLayout>

Try this, you'll have to add the string references and background again, I removed them so I wouldn't have errors
<?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="vertical">
<TextView android:id="#+id/NotesWelcomeTextView"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:text="NotesWelcomeText" />
<ListView android:id="#+android:id/list" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_above="#+id/AddItemToListViewLinearLayout"
android:layout_below="#+id/NotesWelcomeTextView">
</ListView>
<LinearLayout android:id="#+id/DeleteAllItemsFromListViewLinearLayout"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="1" android:visibility="invisible"
android:layout_alignParentBottom="true">
<Button android:id="#+id/CancelButton2" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Cancel" />
<Button android:id="#+id/DeleteAllButton" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Delete" />
</LinearLayout>
<LinearLayout android:id="#+id/DeleteItemFromListViewLinearLayout"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="1" android:visibility="invisible"
android:layout_alignParentBottom="true">
<Button android:id="#+id/CancelButton" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Cancel" />
<Button android:id="#+id/DeleteButton" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Delete" />
</LinearLayout>
<LinearLayout android:id="#+id/AddItemToListViewLinearLayout"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:visibility="gone" android:layout_alignParentBottom="true">
<EditText android:id="#+id/AddItemToListViewEditText"
android:layout_width="250dp" android:layout_height="wrap_content"
android:layout_weight="1">
</EditText>
<Button android:id="#+id/AddItemToListViewButton"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_weight="1" android:text="Add" />
</LinearLayout>

Give your ListView a weight of 0 and set its height to 0. This will tell the ListView to only take up the space that is not use by other views.
<ListView ...
android:layout_weight="0"
android:layout_height="0"
...
/>
