I'm working on a information orientated app using the master/detail flow and so far, so good. I would like to add images to the TextView, but it's formatted differently then what I've experienced in the past and I'm lost. from my understanding of what I've read while searching is that the scrolling text is "newer" when generating the Master/detail activity, therefore I haven't found any information on this specific issue. I would also like to pass the images in using the content activity, so it would be-
addItem(new Item(ID,Name,Detail,Image1,Image2));
what the detail XML file looks like
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/bobblehead_detail"
style="?android:attr/textAppearanceMedium"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
android:textIsSelectable="true"
tools:context="com.example.johnson.fallout4bobbleheadlocations.BobbleheadDetailFragment" />
I tried adding ImageView's under it, but I received errors.
tl;dr I would like to add 2 images under the scrolling TextView.
I am not sure if I clearly understand what you mean but looking at your xml it seems to me that you need to add a layout (either relative or linear) to your xml file and then add a textview and two imageviews (or whatever you want) into that layout.
Something like this:
<RelativeLayout 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"
android:padding="16dp" tools:context="com.example.somefragment">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/some_id2"
android:text="Here is your text"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/some_id"
android:src="#drawable/image1"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/some_id3"
android:src="#drawable/image2"/>
</RelativeLayout>

I'm trying to set up a basic BottomActionBar with an attached FloatingActionButton. Currently, everything seems to work, aside from the background of the bar. If I use android:background="some_background_color", the bar is filled in with the desired color.
The problem is that I want my FAB to be cradled, and this approach seems to be incompatible with fabCradleMargin and fabCradleRoundedCornerRadius, as the background bar is unaffected by modifying these values.
All tutorials indicate that app:backgroundTint="some_background_color" is the way to go, but my action bar remains unaffected by this. I've set my API to >= 21, so as far as I know, there are no issues there.
My XML file:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintBottom_toBottomOf="parent">
<com.google.android.material.bottomappbar.BottomAppBar
android:id="#+id/bottom_app_bar"
style="#style/Widget.MaterialComponents.BottomAppBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
app:backgroundTint="#color/colorPrimary"
app:fabAlignmentMode="center"
app:fabAttached="true"
app:fabCradleMargin="10dp"
app:fabCradleRoundedCornerRadius="10dp" />
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_add_white_24dp"
app:layout_anchor="#+id/bottom_app_bar"
app:layout_anchorGravity="center_horizontal"
app:fabSize="normal"/>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
The backgroundTint has no effect on the bar; it remains completely white.
Sorry if this is an elementary question; I'm quite new to Android and have spent quite a while searching for a solution to no avail.
I tested your code
it shows an error for BottomAppBar so I findout this code app:fabAttached="true" is Undefined...
remove it and it will work perfectly.
Goodluck.
In xcode I can display a PDF as a single continuous page, with the PDF width being equal to screen width and then the vertical scroll being the height of PDF for said width. No problems
Currently converting same app to Android and having some difficulty implementing same PDF view
Basically I have a PDF page that is very long (single page). I don't want to swipe between pages, but instead like in my iOS app, have the PDF document fill the Android screen width wise, and then scroll vertically to show rest of PDF
I'm using com.github.barteksc.pdfviewer.PDFView to render my PDF
In my xml for the activity I have:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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"
android:fillViewport="true">
tools:context=".ProfileActivity">

<com.github.barteksc.pdfviewer.PDFView
android:id="#+id/pdfView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
</ScrollView>
I've tried changing the layout_height to "wrap_content" for scrollView, Linear and pdf, as that would seem appropriate, but whenever I do this I get a blank screen. It seems that doing so resulting in no height attribute so the view collapses completely
I get:
What I want:
Would really appreciate any further help, this is really my only sticking point. I wish android had PDFKit (similar) as I found that quite easy to use and implement
Well there is an answer!
I had to 'upgrade' to the latest version: 3.1.0-beta.1 and use the:
.pageFitPolicy(FitPolicy.WIDTH)
Combined with my XML:
<ScrollView 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:layout_width="match_parent"

android:layout_width="match_parent"
android:layout_height="0dp"
android:orientation="vertical">
<com.github.barteksc.pdfviewer.PDFView
android:id="#+id/pdfView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
</ScrollView>
Worked perfectly. I hope this helps others
I have a PlayerView that takes up the top half of the Activity in portrait orientation with the bottom half of the screen showing some text.
I need to have the controller under the video without overlapping the video content (it will always be shown). By default when a user touches the video the controller appears at the bottom of the video covering the bottom part of the video. I my case I need the controller to stick under the video with no intersections with the video content.
I went through SimpleExoPlayer and PlayerView APIs but I haven't found any way to do so.
Question: How can I place the controller under the video with ExoPlayer?
Here is how the layout looks like:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.exoplayer2.ui.PlayerView
android:id="#+id/video_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_below="#id/video_view"
android:scrollbars="vertical" />
</RelativeLayout>
This will push the controls down to the bottom of the screen:
<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">
<com.google.android.exoplayer2.ui.PlayerView
android:id="#+id/video_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:use_controller="false" />
<com.google.android.exoplayer2.ui.PlayerControlView
android:id="#+id/controls"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/video_view"
app:show_timeout="0" />
</RelativeLayout>
Then in Java:
PlayerView videoView = findViewById(R.id.video_view);
PlayerControlView controls = findViewById(R.id.controls);
controls.setPlayer(videoView.getPlayer());
Edit: Modified my answer to suggestion from #RashimiGautam
Refer to the answer by #Pierre.
Also to remove controller from above PlayerView, in that case, #id/video_view by writing player.showController(false) in java file.
You can also use app:use_controller:false in the xml.
So you will the only the video without controller on top. And link it to a new controller, in that case, #id/controls at the bottom of the video.
This might give you an idea, also have you tried to override the controls?
As an example, suppose we want our playback controls to consist of only a play/pause button positioned in the center of the view. We can achieve this by creating exo_playback_control_view.xml file in the application’s res/layout directory, containing:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageButton android:id="#id/exo_play"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_gravity="center"
android:background="#CC000000"
style="#style/ExoMediaButton.Play"/>
<ImageButton android:id="#id/exo_pause"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_gravity="center"
android:background="#CC000000"
style="#style/ExoMediaButton.Pause"/>
</FrameLayout>
Note that in the layout #id/exo_play and #id/exo_pause are standard ids defined by the ExoPlayer library. Use of standard ids is required so that child views can be identified, bound to the player and updated in an appropriate way. A full list of the standard ids for each view can be found in the Javadoc for PlaybackControlView and SimpleExoPlayerView. Use of each standard id is optional.

I'm creating an free Android application and I'm using OpenStreetMap (OSMdroid library). I have a question. On the webpage: https://www.openstreetmap.org/copyright
I have read, that I should put a text in the corner of map activity (#OpenStreetMap contributors).
How to do this?
I'd like my app to be comply with the OSM license.
Regards
There is a built in copyright overlay for displaying the notice based on the current tile source.
Edit, sample code is below
//Copyright overlay
mCopyrightOverlay = new CopyrightOverlay(context);
mMapView.getOverlays().add(this.mCopyrightOverlay);
Basically, whatever the current tile source is, the text overlay will be drawn.
When you have your layout file simply add a TextView with "#OpenStreetMap contributors" to it. (I recommend to use a RelativeLayout)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<org.osmdroid.views.MapView android:id="#+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:text="OpenStreetMap Contributors" />
</RelativeLayout>
I saw in other apps that on startup they all show this and a few seconds later it is fading out so you can use a delayed animation for that.
textView.animate().setStartDelay(3000).alpha(0).setDuration(1000).start();
I'm trying to place an image view at the top of the screen, but it has some type of margin above and below it. So I tried adjustViewBounds = true, and it worked but then it wouldn't reach the sides of the screen. I just want it to be flush with the top of the screen, and reach the sides. Any suggestions?

If it is just colored title bar - then it is make sense to use just View for example and set background property to needed color. If You have custom image for that and can not adjust it with default ImageView properties - then You can make 9Patch from your image and use it as a background also (in 9patch you decide by yourself how to scratch image and where to place content). You can find 9patch tool in android SDK. More info about 9patch:
http://developer.android.com/reference/android/graphics/NinePatch.html
I had this same problem. What I ended up doing was using a negative margin on the top of the ImageView like so:
android:layout_marginTop="-4dp"
You may have to play around to find the optimal number of dp for you. Hope this helps.
