I'm adding the Toolbar inside my app but seems I have a issue. In the app I should have a button that is on the right of the screen, and the title in center. But when I go deeper in the app I should display the back arrow on the left, by doing getSupportActionBar().setDisplayHomeAsUpEnabled(). And this is working fine but when I add the back button the text moves to the right so the back button can have some space I guess. Can someone tell me how can I have my button on the right and the title always in the center, no mather if the back button is displayed or not?
Here is my toolbar xml layout code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:padding="5dp"
tools:ignore="MissingPrefix">
<RelativeLayout
android:id="#+id/toolbar_info_holder"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"
android:textColor="#color/actionbar_title_color" />
<ImageView
android:id="#+id/toolbar_image"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_alignParentRight="true"
android:layout_centerVertical="true" />
<TextView
android:id="#+id/toolbar_count"
android:layout_width="13dp"
android:layout_height="13dp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#drawable/red_circle"
android:gravity="center"
android:text="4"
android:textColor="#color/white"
android:textSize="9sp" />
</RelativeLayout>
</android.support.v7.widget.Toolbar>
What worked for me is to set :
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
to the child view of the Toolbar, which is a LinearLayout for me (and a RelativeLayout for you). It sounded weird to me first but it's working so I won't complain.
First of all, a few general tips. This is the exact purpose behind the Android Hierarchical view. Use that to figure out what the container object of the back button is, how everything fits together, etc.
I suspect you can resolve your issue to some extend by changing some of the wrap_content to match_parent. Specifically, I suspect that changing it in your RelativeLayout for the layout_width will do the trick. But even if that doesn't, use the Hierarchical view to get a better understanding of exactly what happens when you are playing around, and it should help point you in the right direction.
You may have an activity title set, wich would prevent the logo from being centered on the action bar.
Try:
getActionBar().setDisplayShowTitleEnabled(false);
For v.7:
getSupportActionBar().setDisplayShowTitleEnabled(false);
This comes from this question and answer. Credit to #Fillipo Mazza.
Hope it helps.
Little late on this post, but will explain how it can work.
You can use custom view for your toolbar using following code.
supportActionBar?.setCustomView(R.layout.app_bar_title)
supportActionBar?.displayOptions = ActionBar.DISPLAY_SHOW_CUSTOM
What basically happens is, app_bar_layout is added as custom view inside Toolbar.
So let's say the need is to show title in the center along with back key or action buttons on right side.
We can create layout like this.
<?xml version="1.0" encoding="utf-8"?>
<TextView 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:id="#+id/app_bar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center"
tools:text="HOME" />
This textview will attach inside Toolbar layout and align itself in center of the Toolbar layout. Even if you add back key or action menu, it shall remain in the center.

I'm using a toolbar which works pretty well for the most part until I started adding widgets inside it. I have a checkbox and button declared inside the toolbar but would like them to appear at the far end of the toolbar and working towards the title. I.e. the title remains on the left starting from the margin, but icons are added from the right. how do I go about this? I tried changing layout direction, but it just appeared Arabic like..
As you have not shown your code, supposing that your toolbar.xml is somewhat like this.
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/accent_color"
android:minHeight="?attr/actionBarSize"
android:layout_alignParentTop="true"
tools:context=".MyActivity"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/save"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_gravity="right" //might be the missing part
android:textColor="#color/white"
android:text="SAVE"/>
</android.support.v7.widget.Toolbar>
all you have to do is add gravity
android:layout_gravity="right"
You can use RelativeLayout as a child layout in toolbar and add icons in it then you can give alignment(left,right etc) to those icons
The layout image
Hi! I'm using the ActionBar tabs, one activity and four fragments and what I'm trying to do is place the icon and the text in the center of the tab.
I tried this technique but it didn't work. I also tried setting the name="android:gravity to center. Also, I know it's not the best practice but I tried adding right padding to the tabs. I used vertical orientation in the TabView style to get the icons above the text.
You must create layout: abs_layout
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:layout_width="110dp"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Title"
android:textColor="#ffffff"
android:id="#+id/action_bar_title"
android:textSize="18sp" /></RelativeLayout>
and in OnCreate() add this
getSupportActionBar().setCustomView(R.layout.abs_layout);
I have a edittext and a button in a relative layout. Here is the xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="5sp" >
<Button
android:id="#+id/action_home_button"
android:layout_width="35sp"
android:layout_height="35sp"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:background="#drawable/home_button" />
<EditText
android:id="#+id/action_search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toRightOf="#+id/action_home_button"
android:focusable="true"
android:focusableInTouchMode="true"
android:hint="Some hint..."
android:textColor="#FFFFFF"
android:textColorHint="#DDDDDD" />
</RelativeLayout>
<ImageView
android:layout_width="match_parent"
android:layout_height="5sp"
android:layout_alignParentBottom="true"
android:background="#EC9D21" />
</RelativeLayout>
The problem is that the button is centered in the RelativeLayout just fine, but my EditText is aligned to the top of the layout. Is there anything that I'm missing? Thank you in advance.
Edit Above I updated my xml. I set this as a custom view of my action bar. But that should not make a difference, since the button has no problem aligning to center vertical. Thanx
Edit EditText should be aligned center vertical
The standard EditTexts in some themes seem to have some built in padding or margin around and/or under it. If you wish to eliminate this issue, then I would heavily suggest either using a nine patch, background color, or some other form of custom background.
Trying to set a negative bottom margin or something crazy might fix the issue for one standard EditText, but you have to be careful between Android versions as their EditTexts can have different themes and give rather unexpected behavior.
As for why the theme designers chose to have this gap underneath is beyond me. My best guess would be that is their way of "saving face" when the developer doesn't add a margin between vertically aligned EditTexts?
+1 for Uxonith. Changing the background seemed to do the trick eg. android:background="#000000". For me this works fine, because I had to change the background anyways, but if you need the standard edit text, this will not be a solution.
An app I am working on needs to have two buttons anchored to the bottom of the screen. The technique I've used in the past is to declare a RelativeLayout for the buttons within a parent RelativeLayout (height = fill_parent) and set align_parent_bottom to true. This is declared first and has an id so the next child layout can declare itself to be above the buttons' RelativeLayout.
However, the screen I'm currently working on has a strange problem - there is a large empty gap before the first View object appears:
Here is my layout XML
Can anyone spot where my problem is? Is there a better way to arrange my buttons?
Try this Code , It will work .
Problem is android:layout_above="#id/alarm_details_buttons_layout"
in Scroll View
Edited Code
I checked your code and here is the modification in your buttons layout:
<RelativeLayout
android:id="#+id/alarm_details_buttons_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true" >
<Button
android:id="#+id/alarm_details_return_to_list_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="your text here"
android:textSize="15sp" />
<Button
android:id="#+id/alarm_details_update_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/alarm_details_return_to_list_button"
android:state_enabled="false"
android:text="your text here"
android:textSize="15sp" />
</RelativeLayout>
fixed. http://pastebin.com/ucHwzJQP
Note i removed all "#string/", will need to be added back.
I solved the 'gap' problem. As I have set the scroll view to be positioned above the buttons RelativeLayout, I also had to force it to align with it's parent's top:
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_above="#id/alarm_details_buttons_layout"
android:orientation="vertical" >
I am having a problem getting the ListView to display properly. It currently looks like this with the following xml code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/favs_main">
<Button
android:text="Return to Home"
android:id="#+id/return_button"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:textSize="15sp"/>
<ListView
android:id="#+id/favsListView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="180dp"
android:layout_above="#id/return_button"/>
</RelativeLayout>
If you notice the list is down on the screen. I want it to be just below the favorites text instead of just above the return to home button. The catch however is that I always want the button to show and the list view to just occupy the space between the favorites text and the button. The text is from the background image so I can't just align below that. So even with 100 items I would still like to show the button.
Thanks for the help
If the word "favorites" is part of a background image as suggested in the RelativeLayout's background attribute, then you won't be able to align an element below it without using hacky margins or something to that effect. If you want to align an element below the word, separate that into a different ImageView and set the layout_below of the ListView to the id of that ImageView. To get an element to align properly in between two other elements, use a combination of layout_above and layout_below.
Couldn't you just align the ListView to the Parents' Top and set a margin for the ListView so that it is below the Text of the Background?
Also you could change the background to provide the Text in an ImageView and align the ListView to be below the ImageView.
Instead of trying to make a persistent View always show up under the ListView and align it (which you can do, see other suggestions), you might want to take a look at using a footerView:
http://developer.android.com/intl/de/reference/android/widget/ListView.html#addFooterView
"Add a fixed view to appear at the bottom of the list."
Note that it can be another layout too if you eventually need to do more than just one Button.
this my listview which have multiple entries and textview and button fixed in the botton. i haven't inserted background. try this hope it will help.

You could use a simple LinearLayout and use the weight attribute on the ListView :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="#drawable/favs_main">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ListView
android:id="#+id/favsListView"
android:layout_width="wrap_content"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_marginTop="180dp"/>
<Button
android:text="Return to Home"
android:id="#+id/return_button"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_centerHorizontal="true"
android:textSize="15sp"/>
</LinearLayout>
