I am trying to implement a screen with a map and on top on the map it should have a textbar displaying text but for some reason my textbar always goes below the google map view.
I tried to look up for relateable questions but no success with their answers. The picture is attached below to give some more gudience. Code is below.

Image of desirable output
Try the next layout. If you want to display something in front then you must put it at last in the layout.
EDIT
Try this code instead. I´m using it in a personal project and show buttons in front of the map. But of course im using a SupportMapFragment, maybe you can try using it too.
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<fragment
android:id="#+id/map"
class="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="250dp"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|end"
android:gravity="top">
<!-- Put any TextView, Imageview, Button, etc inside -->
<LinearLayout/>
</FrameLayout>
Hope it helps!
try using this in your textView
android:layout_alignParentTop="true"
layout_alignParentTop
If true, makes the top edge of this view match the top edge of the
parent. Accommodates top margin.
May be a boolean value, such as "true" or "false".
You can also try using
android:layout_alignTop
which Makes the top edge of this view match the top edge of the given anchor view ID. Accommodates top margin.

I have a linear layout which contains a set of child views (mixture of text, images and other layouts).
I want to grey out the linear layout and all the child views so they look disabled (similar to how a button works).
Is this possible to achieve? I know i can set a colour filter when painting on the canvas, is there something similar for layouts?
Another way is to call setEnabled() on each child (for example if you want to do some extra check on child before disabling), check out this answer:
https://stackoverflow.com/a/7069377/4840812
You can use Frame-layout
Using TEST ONE you can achieve above text view like disabled. You can set root layout clickable false for actually disable views inside layout.
TEST TWO is for understanding purpose. Like you need to manage order of view to show effect.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--THIS IS TEST ONE-->
<TextView
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_marginTop="150dp"
android:background="#000000"
android:gravity="center"
android:text="TEST DATA"
android:textColor="#android:color/white"
android:textSize="30sp" />

android:gravity="center"
android:text="TEST DATA"
android:textColor="#android:color/white"
android:textSize="30dp" />
</FrameLayout>
To achieve your layout you can use the RelativeLayout. In RelativeLayout you can use the 2 different views or LinearLayout. In first layout you can add views according to your need, and In second layout you can set the alpha colorcode for disable the layout.
Please try below code:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/demo_img_1" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/demo_img_1"
android:layout_marginLeft="20dp"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/trans"/>
</RelativeLayout>
Here is output for code:
I want to display a custom text (mainly person info) inside an image like it's shown above. How can I do it in android? For example, I have a known size of this image (it differs from device to device) and want to display it with the different text size inside it in the special place.
You can use, for example, RelativeLayout.
Make your ImageView be match_parent and use some container for your text lines in bottom of parent RelativeLayout.
Example:
<?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">
<ImageView
android:scaleType="fitXY"
app:srcCompat="#drawable/ic_launcher_background"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:padding="20dp"
android:background="#92fffaaa"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="200dp">
<TextView
android:textSize="20sp"
android:text="Some test text"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</RelativeLayout>
Result:
Try this (adjust dimensions as your requirement)
<RelativeLayout
android:layout_width="200dp"
android:layout_height="150dp">
<ImageView
android:scaleType="centerCrop"
android:src="#drawable/your_image"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:background="#64000000"
android:padding="8dp"
android:gravity="center_vertical"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:text="Title"
android:textColor="#ffffff"
android:textSize="16sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:text="Sub Title"
android:textColor="#ffffff"
android:textSize="14sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
I've done something similar previously.
Use Framelayout.
Add ImageView in frame layout with match_parent constraints.
Add LinearLayout having background="#80000000" and layout_gravity="center" in FrameLayout which contains your two TextViews.
Let me know in case this does not work.
Is there a generally accepted way of doing this? My home screen initially looked like the below image, using the below code, to prompt the user to start a game.
Original home screen
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.example.android.snake.SnakeView
android:id="#+id/snake"
android:layout_width="match_parent"
android:layout_height="match_parent"
tileSize="24" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/text"
android:text="#string/snake_layout_text_text"
android:visibility="visible"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center_horizontal"
android:textColor="#ff8888ff"
android:textSize="24sp"/>
</RelativeLayout>
</FrameLayout>
This worked with no errors, but I needed to add items for user input (EditText) and show last 5 scores (Button) and wanted this prompt below it rather than putting the player through multiple screens. From what I've read, I should be able to embed a FrameLayout inside a RelativeLayout with no conflicts, but it only works to the Show Scores button and the game prompt is missing. When I check it in design view, I am also now getting an error that the bottom half (which is now showing) is failing to instantiate the class that would allow the game to play. I am simply beside myself on how to correct this and would like to understand what I have done wrong so as to not allow this to happen again on future projects. Below is the modified code that causes the errors.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Username"
android:id="#+id/textViewName"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/editTextName"/>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="?android:attr/buttonStyleSmall"
android:text="Add"
android:id="#+id/btnAdd"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Last 5 Games"
android:id="#+id/btnLastFive"/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.example.android.snake.SnakeView
android:id="#+id/snake"
android:layout_width="match_parent"
android:layout_height="match_parent"
tileSize="24" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/text"
android:visibility="visible"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center_horizontal"
android:textColor="#ff8888ff"
android:textSize="24sp"/>
</RelativeLayout>
</FrameLayout>
</LinearLayout>
Proposed layout
You should add the namespace of the custom view com.example.android.snake.SnakeView on your root layout, and add the namespace prefix before the declaration of your custom Views attributes.
So assuming the namespace is "app", tileSize becomes for example app:tileSize
<LinearLayout
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:orientation="vertical">
......
<com.example.android.snake.SnakeView
android:id="#+id/snake"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:tileSize="24" />
.....
</LinearLayout>
It also seems that you have removed the text content "Snake Press up to play" from your TextView #+id/text, otherwise you won't be able to see it.
Element is always displaying at top of the screen. I tried different ways to fix but out of luck. I want to place element at any location of the screen. This is fragment screen.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="myapp.com.myapp1.fragments.AddPeopleFragment">
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:layout_editor_absoluteX="8dp"
tools:layout_editor_absoluteY="159dp"
android:text="three"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:layout_marginStart="110dp"
android:layout_marginTop="167dp" />
</FrameLayout>
Have you ever noticed these lines of code ?
"android:layout_alignParentTop="true"
android:layout_alignParentStart="true""
if you want to use absolute layout, do not bother these code;
eg:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="myapp.com.myapp1.fragmants.FragmantAddPeople">
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:layout_editor_absoluteX="8dp"
tools:layout_editor_absoluteY="159dp"
android:text="three"
android:layout_marginStart="110dp"
android:layout_marginTop="167dp" />
</android.support.constraint.ConstraintLayout>
you can place the item(which in case is the button) anywhere by changing the dp Value of absoluteX and absoluteY;``
I want to make my layout like this as per below picture. this image i am able to see in iphone devices.
Here i used frame layout to achieve make overlays of top and bottom image bar on imageview but after using frame layout i can only able to see top imagebar overlay not bottom image bar? why its happens?
Forgot about the content of top and bottom iamge bar.. i am focusing to achieve this functionality.
Please make me correct if i am wrong in my code.
xml file code :
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<include
android:id="#+id/top_bar"
layout="#layout/item_below_image_bar"
android:gravity="top" />
<it.sephiroth.android.library.imagezoom.ImageViewTouch
android:id="#+id/image"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:adjustViewBounds="true"
android:contentDescription="#string/descr_image"
android:scaleType="fitXY" />
<include
android:id="#+id/below_bar"
layout="#layout/item_below_image_bar"
android:gravity="bottom" />
</FrameLayout>
per android documentation
Child views are drawn in a stack, with the most recently added child on top.
so you need to arrange your layout as follows
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<it.sephiroth.android.library.imagezoom.ImageViewTouch
android:id="#+id/image"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:adjustViewBounds="true"
android:contentDescription="#string/descr_image"
android:scaleType="fitXY" />
<include
android:id="#+id/top_bar"
layout="#layout/item_below_image_bar"
android:gravity="top" />
<include
android:id="#+id/below_bar"
layout="#layout/item_below_image_bar"
android:gravity="bottom" />
</FrameLayout>
in this case the actual location of the view is not determined by the order that the views are declared in the xml. For a linear layout this would be true however not so with the FrameLayout, in a framelayout the location is determined by gravity so your views will still be placed in the correct locations and they will be loaded in order they were declared, so first is the image view, then the first include is placed on top of that, then the second include is placed on top of that (however in this case they dont intersect so it doesn't matter).
edit2: after chatting with sam we were able to figure out the problem here's our solution
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:id="#+id/greenImage"
android:src="#2dff3d"/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="14dp"
android:layout_marginRight="14dp"
>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:layout_alignParentRight="true"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My Label"
android:id="#+id/textView"
android:layout_centerVertical="true"/>
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginLeft="14dp"
android:layout_marginRight="14dp">
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:layout_alignParentRight="true"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My Label"
android:id="#+id/textView1"
android:layout_centerVertical="true"/>
</RelativeLayout>
</FrameLayout>
note the usage of layout_gravity as apposed to just gravity.
