Custom alert dialog view does not show things set dynamically

I have made an alert dialog which shows a custom view,
Java Code
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.about_me_alert, null);
CircleImageView imageView = view.findViewById(R.id.image);
Glide.with(view).load("https://example.com/example.jpg").into(imageView);
TextView title = view.findViewById(R.id.title);
title.setText("This is a title");
TextView note = view.findViewById(R.id.note);
note.setText("This is a note");
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setView(view);
builder.setPositiveButton("Okay", (dialog, which) -> dialog.dismiss()).show();
XML Layout- about_me_alert.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="match_parent"
android:background="?attr/cardbackground"
android:orientation="vertical">
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/image"
android:layout_width="128dp"
android:layout_height="128dp"
android:layout_centerHorizontal="true"
android:layout_margin="8dp" />
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/image"
android:layout_centerHorizontal="true"
android:layout_marginTop="8dp"
android:textColor="#color/white"
android:textSize="16sp" />
<TextView
android:id="#+id/note"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/title"
android:layout_centerHorizontal="true"
android:layout_margin="8dp"
android:textColor="#color/white"
android:textSize="16sp" />
</RelativeLayout>
When alert is shown, it reserves space for the imageview, and two textviews but does not set text or image.
NOTE: This only happens when I make a production apk for release, not while I am testing on my phone.

How to creat Dialog PopUp window with custom Layout?

I'm trying to create a dialog popup window with a custom layout, but my custom layout height and popup window height is not matching. Also, the popup window is hiding a button. What should I do, how can I match my popup window height with a custom layout?
Please help me.
I want my popup window to look like this
But it is looking like this

popup dialog code
popAddPost = new Dialog(this);
popAddPost.setContentView(R.layout.pop_up_confirm_pickup);
//popAddPost.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
//popAddPost.getWindow().setLayout(Toolbar.LayoutParams.MATCH_PARENT,Toolbar.LayoutParams.WRAP_CONTENT);
popAddPost.getWindow().getAttributes().gravity = Gravity.BOTTOM;

In your xml, the parent layout is using RelativeLayout LayoutParams on a ConstraintLayout
Remove android:layout_alignParentLeft="true" and android:layout_alignParentEnd="true"
ConstraintLayout also doesn't support layout_gravity so you can also remove that.
<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"
android:background="#drawable/rectangle"
android:layout_marginBottom="88dp">
Code
popAddPost = new Dialog(this);
popAddPost.setContentView(R.layout.pop_up_confirm_pickup);
Objects.requireNonNull(popAddPost.getWindow()).setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
popAddPost.show();
EDIT
To position the dialog at the bottom use this:
Window window = popAddPost.getWindow();
WindowManager.LayoutParams params = window.getAttributes();
params.gravity = Gravity.BOTTOM;
window.setAttributes(params);

This is how i do it:
private AlertDialog alertDialog;
alertDialog = buildDialog();
alertDialog.show();
private AlertDialog buildDialog(){
final AlertDialog dialogBuilder = new AlertDialog.Builder(context).create();
LayoutInflater inflater = LayoutInflater.from(context);
View dialogView = inflater.inflate(R.layout.dialog, null);
dialogBuilder.setView(dialogView);
dialogBuilder.setButton(DialogInterface.BUTTON_NEGATIVE, "CLOSE", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialogBuilder.dismiss();
}
});
return dialogBuilder;
}

I think dialog is not a good solution for your problem as a dialog would have its own window with overlay.
As I can see you want the dialog to be at the bottom of the screen, which makes the BottomSheet as a perfect match for your problem.
You can use the following to get started with:
https://www.androidhive.info/2017/12/android-working-with-bottom-sheet/
https://material.io/develop/android/components/bottom-sheet-behavior/
https://medium.com/#droidbyme/android-bottom-sheet-7e9cfcec6427
With BottomSheet, you would get a separate window just like dialog without the overlay you are facing.

I am having toolbar in MainActivity. This is my fragment i want to set title, image and back button inside the toolbar. Here i am using bottom navigation to change the fragments. Each and every fragment i want to set different title and image. I have to set title as center of the toolbar and back button as right corner of the toolbar.

In your MainActivity add these lines in OnCreate() method
if (getSupportActionBar() != null) {
getSupportActionBar().setTitle("My Activity Title");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
To use Back arrow you can write this code outside onCreate()
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
Toast.makeText(this, "Back button pressed", Toast.LENGTH_SHORT).show();
return true;
}
return super.onOptionsItemSelected(item);
}
In you fragment you can change title of Toolbar
getActivity().setTitle("My fragment Title");

You can Create custom Toolbar with ImageView and TextView with your arrow .
include_tool_bar.xml
<com.mastercard.wallet.ui.widget.CustomTextView
android:id="#+id/toolbar_title"
style="#style/Toolbar.TitleText"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical|left"
android:textSize="#dimen/px_48"
app:fontName="InterStateLight"
customviews:fontName="InterStateLight" />
<ImageView
android:id="#+id/toolbar_logo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:contentDescription="#string/adaCitiPayLogoText"
android:src="#drawable/ab_logo"
android:visibility="gone" />
And Add Toolbar
Toolbar toolbar = (Toolbar) appCompatActivity.findViewById(R.id.toolbar);
ImageView logo = (ImageView) toolbar.findViewById(R.id.toolbar_logo);
CustomTextView textView = (CustomTextView) toolbar.findViewById(R.id.toolbar_title);
logo.setVisibility(View.VISIBLE);
logo.setImageResource(logoResourceId);
textView.setVisibility(View.GONE);
appCompatActivity.setSupportActionBar(toolbar);
appCompatActivity.getSupportActionBar().setDisplayShowTitleEnabled(false);

title of the toolbar can be changed from fragment calling this in onActivityCreated
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
((MainActivity) getActivity()).getSupportActionBar().setTitle(getString(R.string.menu_about_us));
((MainActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((MainActivity) getActivity()).getSupportActionBar().setDisplayShowHomeEnabled(true);
}
in your activity make sure to add a toolbar like this.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
and set it in your activity
setSupportActionBar(findViewById(R.id.toolbar));
and for the back press just add a listener and do the needful.
toolbar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_action_back));
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// pop up fragment or take another action
}
});

Android: made a text in RelativeLayout and can't change text in activity?

<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:gravity="center"
android:text="#string/text"
android:textColor="#F0F8FF"
android:textSize="50sp"
android:textStyle="bold" />
This is declaration of the text field in activity_main.xml.
And the activity:
TextView text = (TextView) findViewById(R.id.textView1);
text.setText(napis);
Program crashes when I call setText() in onReasume() and it doesn't do anything when I call setText() in onCreate().
Whole xml file as requested:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:layout_height="match_parent" >

</LinearLayout>
Activity:
text = (TextView) findViewById(R.id.textView1);
text.setText("Your Text");
Can't show more, cause something doesn't work... xf
onCreate():
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView text = (TextView) findViewById(R.id.textView1);
napis="Witaj!";
//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//,........
text = (TextView) findViewById(R.id.textView1);
text.setText("Your Text");
senSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
senAccelerometer = senSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
senSensorManager.registerListener(this, senAccelerometer , SensorManager.SENSOR_DELAY_NORMAL);
//set content view AFTER ABOVE sequence (to avoid crash)
this.setContentView(R.layout.activity_main);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
// Create an instance of Camera
mCamera = getCameraInstance();
// Create our Preview view and set it as the content of our activity.
mPreview = new CameraPreview(this, mCamera);
FrameLayout preview = (FrameLayout) findViewById(R.id.camera_preview);
preview.addView(mPreview);
}
onReasume():
#Override
protected void onResume() {
super.onResume();
senSensorManager.registerListener(this, senAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
}

First of all, what is up with
//set content view AFTER ABOVE sequence (to avoid crash)
this.setContentView(R.layout.activity_main); ??
Can you try doing
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.activity_main, this);
TextView text = (TextView) layout.findViewById(R.id.textView1);
text.setText(napis);
setContentView(layout);
set the contentView only once, towards the end of the method..
Try this, then post logcat if it doesn't work

Change textview dynamically in Viewflipper

pretty easy question here, but I am not a java superuser quite yet.
I am using a ViewFlipper to provide a number of images, and a sliding-drawer to contain text specific to each image. I would like to have the text of the sliding drawer change to a specific string dependent on which child view is currently displayed.
Here is the XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="#+id/previous"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev" />
<Button
android:id="#+id/next"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next" />
</LinearLayout>
<ViewFlipper
android:id="#+id/flipper"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:id="#+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="#drawable/image1"></ImageView>
<ImageView android:id="#+id/imageView2" android:layout_height="wrap_content" android:layout_width="wrap_content" android:src="#drawable/image2"></ImageView>
</ViewFlipper>
</LinearLayout>
here is the java:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
flipper = (ViewFlipper)findViewById(R.id.flipper);
next = (Button) findViewById(R.id.next);
previous = (Button) findViewById(R.id.previous);
imageview1 = (ImageView)findViewById(R.id.imageView1);
imageview2 = (ImageView)findViewById(R.id.imageView2);
next.setOnClickListener(this);
previous.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (v == next) {
flipper.setInAnimation(inFromRightAnimation());
flipper.setOutAnimation(outToLeftAnimation());
flipper.showNext();
}
if (v == previous) {
flipper.setInAnimation(inFromLeftAnimation());
flipper.setOutAnimation(outToRightAnimation());
flipper.showPrevious();
}
}
I'm sure the answer is really obvious, but that's why I need your help....THANKS!

When you call showNext() and showPrevious(), update your TextView to match.
