Move buttons to bottom half on android - android

I've been trying to find a way to move my buttons to the bottom half in my xml file. Currently they are in the top half.
I am trying to follow this solution found here, but I am afraid that it is inapplicable.
Put buttons at bottom of screen with LinearLayout?
My buttons.xml is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="1">
<TableLayout android:id="#+id/tableLayout1"
android:layout_height="wrap_content"
android:layout_width="fill_parent" />
<Button
android:id="#+id/block_button"
style="?android:attr/borderlessButtonStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="right|center_vertical"
android:layout_weight="0.09"
android:background="#ff5ac3ff"
android:drawableLeft="#drawable/ic_action"
android:gravity="center_horizontal|center_vertical"
android:text="#string/block_apps"
android:textSize="22sp" />
<Button
android:id="#+id/security_settings_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff5ac3ff"
style="?android:attr/borderlessButtonStyle"
android:layout_weight="0.09"
android:drawableLeft="#drawable/ic_settings"
android:gravity="center_horizontal|center_vertical"
android:text="#string/security_settings"
android:textSize="22sp"/>
<Button
android:id="#+id/blacklist_whitelist_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff5ac3ff"
style="?android:attr/borderlessButtonStyle"
android:drawableLeft="#drawable/ic_blacklist_red"
android:gravity="center_horizontal|center_vertical"
android:text="#string/blacklist_whitelist"
android:textSize="22sp"
android:layout_weight="0.09"/>
</LinearLayout>


You should try something like this. Basically, if you're using layout_weight, you need to set the height or width (depending or your orientation: vertical or horizontal) to "0dp". Otherwise, the view won't use the weight attribute. Try this xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="#+id/emptySpace"
android:layout_height="0dp"
android:layout_width="fill_parent"
android:layout_weight="3" />
<Button
android:id="#+id/block_button"
style="?android:attr/borderlessButtonStyle"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_gravity="right|center_vertical"
android:layout_weight="1"
android:background="#ff5ac3ff"
android:drawableLeft="#drawable/ic_action"
android:gravity="center_horizontal|center_vertical"
android:text="#string/block_apps"
android:textSize="22sp" />
<Button
android:id="#+id/security_settings_button"
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#ff5ac3ff"
style="?android:attr/borderlessButtonStyle"
android:layout_weight="1"
android:drawableLeft="#drawable/ic_settings"
android:gravity="center_horizontal|center_vertical"
android:text="#string/security_settings"
android:textSize="22sp"/>
<Button
android:id="#+id/blacklist_whitelist_button"
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#ff5ac3ff"
style="?android:attr/borderlessButtonStyle"
android:drawableLeft="#drawable/ic_blacklist_red"
android:gravity="center_horizontal|center_vertical"
android:text="#string/blacklist_whitelist"
android:textSize="22sp"
android:layout_weight="1"/>
</LinearLayout>
Btw, I changed your tablelayout to an empty textview, but you should be able to use any other type of view there. It's just there to fill up space.
Also, with layout_weights, be careful with layouts that extend beyond the screen size (like scrollview). That will throw off your weights. Layout weights are best suited for known layout dimensions.


I would suggest you to divide the whole layout into 6 equal LinearLayouts and then set the buttons in the last three layouts..
Try this code..
<LinearLayout android:orientation="horizontal" android:layout_height="fill_parent" android:layout_width="fill_parent">
<LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="fill_parent"></LinearLayout>
<LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="fill_parent"></LinearLayout>
<LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="fill_parent"></LinearLayout>
<LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="fill_parent">
<Button
android:id="#+id/block_button"
style="?android:attr/borderlessButtonStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="right|center_vertical"
android:layout_weight="0.09"
android:background="#ff5ac3ff"
android:drawableLeft="#drawable/ic_action"
android:gravity="center_horizontal|center_vertical"
android:text="#string/block_apps"
android:textSize="22sp" />
</LinearLayout>
<LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="fill_parent">
<Button
android:id="#+id/security_settings_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff5ac3ff"
style="?android:attr/borderlessButtonStyle"
android:layout_weight="0.09"
android:drawableLeft="#drawable/ic_settings"
android:gravity="center_horizontal|center_vertical"
android:text="#string/security_settings"
android:textSize="22sp"/>
</LinearLayout>
<LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="fill_parent">
<Button
android:id="#+id/blacklist_whitelist_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff5ac3ff"
style="?android:attr/borderlessButtonStyle"
android:drawableLeft="#drawable/ic_blacklist_red"
android:gravity="center_horizontal|center_vertical"
android:text="#string/blacklist_whitelist"
android:textSize="22sp"
android:layout_weight="0.09"/>
</LinearLayout>
</LinearLayout>
Please do tell me what the output is..


I've tested this, it should work, you'll have to change the button attributes since I was using test content & images.
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/layout"
android:orientation="vertical"
android:layout_width="fill_parent"

<TableLayout android:id="#+id/tableLayout1"
android:layout_height="wrap_content"
android:layout_width="fill_parent" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="bottom"

How to merge Linear Layout and Table Layout at android?

I'm new android. I have a little bit stack in designing layout for Android. In my scenario, I have two button with Linear Layout. Here my xml.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:background="#color/isp_home_color"
>
<Button
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_weight="1"
android:text="#string/sync_text"
android:background="#color/sync_text_color"
android:id="#+id/btn_syncpin"
android:layout_gravity="left"
android:textStyle="bold"
/>
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="70dp"
android:text="#string/topup_text"
android:background="#color/topup_text_color"
android:id="#+id/btn_topup"
android:layout_gravity="right"
android:textStyle="bold"/>
<!--Table Layout will come here -->
</LinearLayout>
Here image for this.
When I add new TableLayout inside Linear Layout. I got this.
Here my xml for Table Layout.
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</TableLayout>
Actually, I don't want like this. I want two button as shown in first image. Then, next table layout will occur under this two button. Please help me how can I do this layout. Please pointing to me how to make this. Thanks with advanced.

Give orientation as vertical to the LinearLayout not the TableLayout.Put Two buttons in a LinearLayout with orizontal orientation and give orientation "vertical" for the parent LinearLayout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#456789"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF"
android:orientation="horizontal">
<Button
android:id="#+id/btn_syncpin"
android:layout_width="wrap_content"
android:layout_height="70dp"
android:layout_gravity="left"
android:layout_weight="1"
android:background="#123456"
android:text="tring/"
android:textStyle="bold" />
<Button
android:id="#+id/btn_topup"
android:layout_width="wrap_content"
android:layout_height="70dp"
android:layout_gravity="right"
android:layout_weight="1"
android:background="#978969"
android:text="topup_text"
android:textStyle="bold" />
</LinearLayout>
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF" >
</TableLayout>
</LinearLayout>

Check this out, I just checked it on my Machine and it works as desired, although the background preference and the display strings have been removed.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/btn_syncpin"
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_gravity="left"
android:layout_weight="1"
android:textStyle="bold" />
<Button
android:id="#+id/btn_topup"
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_gravity="right"
android:layout_weight="1"
android:textStyle="bold" />
</LinearLayout>
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_below="#+id/linearLayout2">
</TableLayout>
</RelativeLayout>

take Relative Layout as a parent layout.
Following is an example. it will display your buttons and table layout too
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#color/isp_home_color"
android:orientation="horizontal" >
<Button
android:id="#+id/btn_syncpin"
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_gravity="left"
android:layout_weight="1"
android:background="#color/sync_text_color"
android:text="#string/sync_text"
android:textStyle="bold" />
<Button
android:id="#+id/btn_topup"
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_gravity="right"
android:layout_weight="1"
android:background="#color/topup_text_color"
android:text="#string/topup_text"
android:textStyle="bold" />
</LinearLayout>
<TableLayout
android:id="#+id/table"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/linearLayout2" >
</TableLayout>
</RelativeLayout>

This answer tells only implementation of button_bar_layout for all android versions with buttons at the bottom/top of an activity which look like AlertDialog with OK/Cancel buttons.

Android Button layout with big text size

I'm trying to make two identical buttons with the same height, but when the text is too long (the second button) then breaks markup. How can I fix it?
xml layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent">
<Button
android:text="test"
android:layout_height="100dp"
android:layout_width="0dp"
android:layout_weight="1"/>
<Button
android:padding="0dp"
android:text="Arterial tension disturbance"
android:layout_height="100dp"
android:layout_width="0dp"
android:layout_weight="1"/>
</LinearLayout>
</LinearLayout>

Add android:singleLine="true"
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent">
<Button
android:singleLine="true"
android:text="test"
android:layout_height="100dp"
android:layout_width="0dp"
android:layout_weight="1"/>
<Button
android:singleLine="true"
android:padding="0dp"
android:text="Arterial tension disturbance"
android:layout_height="100dp"
android:layout_width="0dp"
android:layout_weight="1"/>
</LinearLayout>

use wrap_content instead of 0dp
<Button
android:padding="0dp"
android:text="Arterial tension disturbance"
android:layout_height="100dp"
android:layout_width="wrap_content"
android:layout_weight="1"/>

You can try this: (Edited)
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:weightSum="100" >
<Button
android:layout_width="fill_parent"
android:text="yourText"
android:layout_height="wrap_content"
android:layout_weight="50" />
<Button
android:layout_width="fill_parent"
android:text="yourText"
android:layout_height="wrap_content"
android:layout_weight="50" />

RelativeLayout inside LinearLayout?

I was wondering what I am doing wrong here, why does surrounding these buttons in a RelativeLayout cause an error? I haven't edited layouts much, can I not just stick in a Relative or Linear layout like that?
If I don't surround the buttons in a layout they appear beneath each other, I am just trying to experiment in having them beside each other horizontally.
I think the way I have done this whole layout is bad because vertically it looks quite squished.

As others have pointed out already, you need to define a layout_width and layout_height for your RelativeLayout. This should fix your error, unless there are other issues you have. But I thought it was worth noting what the DOCS say about layouts
A RelativeLayout is a very powerful utility for designing a user interface because it can eliminate nested view groups and keep your layout hierarchy flat, which improves performance. If you find yourself using several nested LinearLayout groups, you may be able to replace them with a single RelativeLayout.
You have many nested LinearLayouts so you may consider using a RelativeLayout for better performance and readability. You can also use android:orientation="horizontal" in a nested LinearLayout to get your buttons next to each other. But, again, a RelativeLayout may be better in your situation instead of having all of the nested layouts.

Your relativeLayout has no size.
Define layout_height and layout_width to it

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">

Linearlayout for different screen sizes

I have a linearLayout which is surrounded by a scrollView in order to make it for smaller screens scrollable. In the linear layout I have 3 childs which are also linearlayout.
This is working fine. But I also want to support larger screens. At the moment I get with a larger screen space left on the bottom of the screen. I want to have the buttons (navigation bar) be always at the bottom. for larger screens (height) I would like to add at the top of the screen an empty view which fills out the space that is more provided by the larger screen.
How can I achieve that? i tried a lot with weight attribute but didnt get it working.
Here the layout:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView

android:background="#8db9f6"
android:layout_width="fill_parent"

Wrap the entire layout in a Relative Layout. Use a relative layout as your root element and set the Linear Layout containing your buttons to layout_alignParentBottom="true" and the ScrollView set to layout_alignParentTop="true".
The LinearLayout containing the buttons and the ScrollView should be direct children of the RelativeLayout.
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout <-- containing the layout minus the buttons
android:id="#+id/SV"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">
<The Rest Of The Layout>
</LinearLayout>
<LinearLayout
android:id="#+id/LLButtons"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Buttons>
</LinearLayout>
</ScrollView>
If you want the buttons to be always at the bottom of the screen alignParentBottom. If you want the buttons to always be at the bottom of the scrollview alignBelow="#id/SV"

android:layout_height="wrap_content" in your inner LinearLayout is your trouble here, changing it to 'fill_parent' should help. In general, you may want to use hierarchyviewer to help troubleshoot layout issues like this.

Android linear layout align center and right

This is what I have:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#FFFFFF">
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:background="#E30000"
android:layout_gravity="center_horizontal|center_vertical"
android:gravity="center_horizontal|center_vertical">
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:gravity="right|center_vertical"
/>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:gravity="right|center_vertical"
android:layout_gravity="center_vertical"
android:background="#E30000">
<Button
android:id="#+id/btnCalls"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/icon"
android:gravity="right|center_vertical"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
And I want this:
So horizontal center align the text and vertical center align the button.
What am I missing? I haven't tried RelativeLayout and I would prefer LinearLayout to work this out.

android:gravity="right|center_vertical"
aligns your TextView to the right. How about center_horizontal?
And your LinearLayouts have the same ID, if there is not more code, then I would delete one of them.

try this one
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#FFFFFF">
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:background="#E30000"
android:layout_gravity="center_horizontal|center_vertical"
android:gravity="center_vertical">
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:layout_weight="1"
android:gravity="center"/>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:gravity="right|center_vertical"
android:layout_gravity="center_vertical"
android:background="#E30000"
android:layout_width="wrap_content">
<Button
android:id="#+id/btnCalls"
android:layout_width="wrap_content"
android:drawableLeft="#drawable/icon"
android:gravity="right|center_vertical"
android:layout_height="wrap_content"
android:layout_margin="5dip"/>
</LinearLayout>
</LinearLayout>
</LinearLayout>

I found none of the answers work exactly as the OP intended, but the RelativeLayout solution was the closest one. Except that the TextView wasn't centered. But, with layout_centerInParent=true, works like a charm:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:layout_centerInParent="true" />
<Button
android:id="#+id/btnCalls"
android:drawableLeft="#drawable/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
</RelativeLayout>

you have used android:gravity="right|center_vertical" in your textview. Use android:gravity="center".

Try to add empty View inside horizontal LinearLayout between element that you want see left and element that you want to see right, e.g.:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

define layout weight for TextView and LinearLayout
set android:layout_weight="1" to TextView
set android:layout_weight="0" to LinearLayout
and also change the layout_width="wrap_content" to LinearLayout
and set layout_gravity="center" to TextView

I think,gravity means the position of things inside the component(for textview,it means the text you have given)in component where layout_gravity means position of component itself in the whole layout.So...
Try Using:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#FFFFFF"
>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:background="#E30000"
android:layout_gravity="right"
android:gravity="center_vertical|right"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right|center_vertical"
android:gravity="center_vertical|center"
android:layout_weight="0.9"
>
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:gravity="center_horizontal"
android:layout_gravity="center_horizontal|center_vertical"
/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right|center_vertical"
android:gravity="center_vertical|right"
android:paddingTop="5dip"
android:layout_weight="0.1"
>
<Button
android:id="#+id/btnCalls"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/icon"
android:layout_gravity="center_vertical"
android:gravity="center"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>

Just use RelativeLayout, and wallaaa!!!
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:gravity="center" />
<Button
android:id="#+id/btnCalls"
android:drawableLeft="#drawable/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
</RelativeLayout>

The solution for this is-
android:gravity="center_vertical"
Normally you'll also have to take care of its parent's position too to make sure it works.
