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'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
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.
So I have a list of images that come from the web, I don't know which color are they and I want to place a text over the ImageView.
My idea is to place the ImageView, an image overlay with transparency gradient over that ImageView and the text above it. I want to mimic this behaviour:
Is there anyway to do this via XML?
When you write the XML for your list items which get inflated in the getView(...) of whatever ListAdapter you've written you can surely do this.
Something like this for the list item:
<?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="match_parent">
<ImageView
android:layout_width="320dp"
android:layout_height="240dp"
android:background="#ACACAC"/>
<RelativeLayout
android:layout_width="320dp"
android:layout_height="240dp"
android:background="#drawable/gradient">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Here is your text"
android:textColor="#000000"
android:layout_alignParentBottom="true"/>
</RelativeLayout>
</RelativeLayout>
Then you create that drawable/gradient. For that you can recycle the answer from here.
Thanks to adityajones I managed to get there :)
So although this is my right answer, I'll mark his as the correct one!
<?xml version="1.0" encoding="utf-8"?>
<ImageView
android:layout_width="fill_parent"
android:layout_height="200dp"
android:scaleType="centerCrop"
android:src="#drawable/image" />
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="200dp"
android:background="#drawable/gradient_image" >
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_margin="6dp"
android:layout_marginBottom="18dp"
android:shadowColor="#000"
android:shadowRadius="7.0"
android:text="This is some random text"
android:textColor="#color/white"
android:textSize="22sp" />
</RelativeLayout>
I'd use a FrameLayout or RelativeLayout. The first View you add to either should be the background ImageView, then obviously you'll need some TextViews and Other ImageViews [or Buttons, or ImageButtons, etc]
Seems like a reasonable layout: a background image, and then one additional view in each corner.
For the gradient, you'll probably want a separate Layout/View at the bottom with a gradient drawable as the background, although I can imagine you might be able to get away with setting the background of one of your TextViews as the gradient.
You do not have to use a gradient drawable file or set it in your xml..
you can do this pragmatically using GradientDrawable Class as explained in this related Question (Create a radial gradient programmatically) then set it as a background for a layout that covers your ImageView, this gives you ability to use different colors and orientations
I'm currently trying to place a progress bar on the top left corner of my screen. However, I'm not quite sure which way is the best way to do it. Should I create a progress bar programatically instead of creating it in the xml? Or should I change my layout around? Thanks. XML below.
XML CODE:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background"
android:focusableInTouchMode="true"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="53dp"
android:layout_marginBottom="5dp"
android:src="#raw/topbar" />
<TextView
android:id="#+id/search_nameOfFeed"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical|center_horizontal"
android:text="Event Name"
android:textColor="#color/black"
android:textSize="18sp" >
</TextView>
<ListView
android:id="#+id/searchfeed_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="0.83"
android:dividerHeight="10.0sp"
android:fadingEdge="none"
android:stackFromBottom="false"
android:transcriptMode="normal" >
</ListView>
</LinearLayout>
The best option for layout when you're wanting to position views in specific areas is FrameLayout or RelativeLayout
RelativeLayout will allow you to place each view relative to each other.
FrameLayout allows you to stack views in a z-index positioning.
Play with both and you may come up with results you're looking for.
The best way to design layouts in android is by creating them in XML so you should do it in XML. You can achieve what you want by adding your ProgressBar before your ImageView
I doubt this is what you're looking for exactly, but another way you might want to implement a non-intrusive progress bar is to put it in the title bar of the activity. Check out this for an example of how to do this.
You can create it either way (In XML or Programatically). If you created it progamatcially, set the gravity to top and if you are creating in XML, use Relative Layout instead of Linear Layout and use android:layout_gravity="top|left". If you want to show it at the center follow the link
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>
