How to display a text view on CameraX preview view?

How to display a text view on CameraX preview view? - android

I want to display a text view in the preview view of camera. It will appear like a label on the camera preview. It should not affect the image. Just appear like a label on preview view. I tried using frame layout but the text view disappears on the preview view
Here's my layout
<?xml version="1.0" encoding="utf-8"?>

android:layout_centerHorizontal="true"
android:layout_margin="10dp"
android:gravity="center"
android:text="Click Image" />
</RelativeLayout>

Thanks for your help everyone. I have found the answer to my question. Actually what I was looking for is called overlay
viewFinder.overlay.add(tvText)

use the element "elevation" with 2dp

Floating Action Button not visible over Mapbox Android

It has been a while since I have developed an Android app. So current dev work is pretty new for me. I am trying to create a Mapbox Android API based app. So far I have successfully loaded User location and move camera based on location change; however, the FAB I have added on the layout is not showing up in either emulator or my phone. It is visible in the XML design view. I believe it might be due to the setContentView(mapView) in MapsActivity.kt which I don't know how is it not able to load the whole layout. Am I missing anything?

Try this
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout

android:layout_margin="16dp"
android:src="#drawable/ic_app_icon"
android:tint="#color/white"
tools:ignore="ImageContrastCheck" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>

Try declaring the floating action button outside the mapview like this:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:mapbox="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<com.mapbox.maps.MapView
android:id="#+id/mapView"
android:layout_width="match_parent"
android:layout_height="match_parent"
mapbox:mapbox_cameraTargetLat="40.7128"
mapbox:mapbox_cameraTargetLng="-74.0060"
mapbox:mapbox_cameraZoom="9.0"/>
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:backgroundTint="#color/purple_200"
android:layout_margin="16dp"
android:contentDescription="#string/fab_description"
android:src="#drawable/ic_plus_icon"
tools:ignore="ImageContrastCheck" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>

I was able to solve this through MapsActivity.kt. As I suspected the setContentView() was getting the wrong view I replaced that part and assigned view manually to mapView. The script looks like this:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_maps)
mapView = findViewById(R.id.mapView)
locationInitHelper = LocationInitHelper(WeakReference(this))
locationInitHelper.setMapView(mapView)
mapView.getMapboxMap().loadStyleUri(Style.MAPBOX_STREETS)
locationEngine = LocationEngineProvider.getBestLocationEngine(this)
locationPermissionHelper = LocationPermissionHelper(WeakReference(this))
onMapReady()
}
Thanks for all the answers though!

what is new defind for MediaRecorder() not Deprecated ?
give me error
java.lang.NoSuchMethodError: No direct method (Landroid/content/Context;)V in class Landroid/media/MediaRecorder; or its super classes (declaration of 'android.media.MediaRecorder' appears in /system/framework/framework.jar!classes2.dex)

Use an if/else to set the property using the supported constructor:
recorder = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) MediaRecorder(this) else MediaRecorder()
Down the road it is possible Jetpack will add a helper function that would do this for you, something like MediaRecorderCompat.newInstance(this). However, it has been so long I think we can assume they will probably not be adding it.

I used the following script in an app published on the Playstore
fun prepare_audio_and_directories(v : View) {
var tempDir : File
// current_filename = (v.findViewById(R.id.audio_filename_xml) as TextView).text.toString()
current_dir = main?.dir!!
tempDir = current_dir
main?.filenameCompletePath = tempDir?.toPath().toString() + "/" +current_filename + "."+ main?.ext
main?.filename_text = current_filename
Log.d("$TAG:prepare_audio_and_directories:main?.filenameCompletePath=", main?.filenameCompletePath!!
)
Log.d("$TAG:prepare_audio_and_directories:main?.filename_text=", main?.filename_text!!)
Log.d("NoiseSuppressor.isAvailable()=", NoiseSuppressor.isAvailable().toString() )
mediaRecorder = MediaRecorder()
mediaRecorder?.setAudioSource(MediaRecorder.AudioSource.MIC)
mediaRecorder?.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4)
mediaRecorder?.setAudioEncoder(MediaRecorder.AudioEncoder.AAC)
mediaRecorder?.setAudioEncodingBitRate(128000)
mediaRecorder?.setAudioSamplingRate(96000);
mediaRecorder?.setOutputFile(main?.filenameCompletePath)
}
The versions I tested it with are API 28,29,30 and 31.

My Recyclerview sometimes display data and sometimes it doesnt

My Recyclerview sometimes needs a refresh to start displaying data, some times it need much time to display the data and sometimes it works like a charm. I even used the same adapter for 2 recycler views one of them displayed data immediately but the other didn't show at all like the the image below:
This problem started to show up when I added another recycler view but in a different fragment that used same adapter. I thought using same adapter was the problem so I created a new one but the problem is still there. Note: I'm using same layout for displaying the recycler view items too. Any Ideas would be really helpful.
Thanks
UPDATE: Codes
Adapter :
import android.graphics.Paint
import android.view.LayoutInflater
import android.view.TextureView
import android.view.View
import android.view.ViewGroup
import androidx.recyclerview.widget.DiffUtil
import androidx.recyclerview.widget.ListAdapter

I Figured out what is the problem. The API takes much time to send the data. So, the recycler view renders the view with null values.

RecyclerView doesn't scroll smoothly initially

I'm using Tmdb API and displaying it in a RecyclerView. The RecyclerView is not scrolling smoothly initially but then is working fine. I've tried to change Recyclerview height to 0dp or match_parent but it's still the same. I've tried also android:nestedScrollingEnabled="true". Please help me to fix this problem in the RecyclerView. Thank you in advance.

I believe this is due to size of the image , I had similar issue try to fit the image you obtain using glide into imageview, I have added centerCrop():
Glide.with(context).load("https://image.tmdb.org/t/p/w300${movieList[position].moviePosterPath}") .centerCrop().into(holder.view.recyclerview_movie_item_moviePosterIV);
If this does not work try to change imageview scaletype or centerCrop() to fitCenter()
