PopupWindow not shown as expected (preview is ok)

I'm trying to show a full screen popup window from a fragment. I was starting the layout for the screen and it looked as expected in the AS screen preview, but it doesn't when it is executed in a device. Basically, it seems that the paddings are omitted. All of them, the paddings in the root of the layout, in the image view which I put to increase the clickable area, in the text input layout (added by theme).
On the other hand, the animation is not shown in some devices but in emulator is.
Here is the layout file ``:

And here you have the kotlin code inside a fragment:
context?.let {
val customView: View = (it.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater).inflate(R.layout.popup_add_item, null)
val popupWindow = PopupWindow(it)
popupWindow.contentView = customView
popupWindow.width = LinearLayout.LayoutParams.MATCH_PARENT
popupWindow.height = LinearLayout.LayoutParams.MATCH_PARENT
popupWindow.animationStyle = R.style.popup_window_animation // TODO Not working in some devices
popupWindow.elevation = 5f
popupWindow.showAtLocation(getBinding().rvDiscounts, Gravity.CENTER, 0, 0)
val btClose = customView.findViewById<ImageView>(R.id.bt_close)
val btAddToCart = customView.findViewById<Button>(R.id.bt_add_item)
val btAdd = customView.findViewById<ImageButton>(R.id.bt_add)
val btLess = customView.findViewById<ImageButton>(R.id.bt_less)
val etQuantity = customView.findViewById<TextInputEditText>(R.id.et_quantity)
btClose.setOnClickListener {
popupWindow.dismiss()
}
btAddToCart.setOnClickListener {
// TODO add to cart
popupWindow.dismiss()
}
btAdd.setOnClickListener {
val currentQuantity = etQuantity.text.toString().toInt()
etQuantity.setText(currentQuantity.inc().toString())
}
btLess.setOnClickListener {
val currentQuantity = etQuantity.text.toString().toInt()
if (currentQuantity > 0) etQuantity.setText(currentQuantity.dec().toString())
}
}
And finally the screenshots, the preview and expected first, the shown on the device second:

To the plus and minus button use a android:margin_start="8dp" and android:margin_end="8dp" respectively, to get some space between the button and the TextInputEditText box.
If you wish to center the zero within TextInputEditText then use android:gravity="center"
The #dimen/padding_start values in these might not be acceptable, so just hardcode the values using android:paddingHorizontal="8dp" and android:paddingVertical="8dp".

<style name="AppTheme.FullScreenDialog" parent="Theme.MaterialComponents.Light.Dialog">
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="android:windowIsFloating">false</item>
<item name="android:windowBackground">#android:color/white</item>
<item name="actionMenuTextColor">#color/colorAccent</item>
</style>
Use this style while creating your Dialog in the fragment like this :
var fullScreenCameraDialog = Dialog(context, R.style.AppTheme_FullScreenDialog)

Set Popup menu to full screen

Note : This is popup menu not popup window.So I request you all to read carefully.
I have implemented pop menu. It is displaying in half of the screen. I want to spread this to entire width of device. I tried to change its style by setting layout_width as match_parent but with no success.
Below is what I tried so far:
Style
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="popupMenuStyle">#style/PopupMenu</item>
</style>
<!-- Change Overflow Menu Background -->
<style name="PopupMenu" parent="android:Widget.Holo.Light.ListPopupWindow">
<item name="android:popupBackground">#888888</item>
<item name="android:layout_width">match_parent</item>
</style>
Below is my java code:
PopupMenu menu = new PopupMenu(getActivity(), tvnext);
for (int i = 0; i < array.size(); i++) {
menu.getMenu().add(1, i, 1, array.get(i).getAccountName());
}
menu.show();
menu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
setUpNextFunctionality(item.getItemId());
return false;
}
});
P.S : Please don't suggest me to use popup window. This is my last option if nothing work.

I got your question. Instead of modify something use new widget which can easily fulfill your necessary and compatible with newer version.
Google introduce new Material concept as Bottom-Sheet
To use it in android you can use git hub libraries like this.

I don't think you can do that without implementing of your own popup window similar to PopupMenu. If you will check MenuPopupHelper::createPopup:
#NonNull
private MenuPopup createPopup() {
final WindowManager windowManager = (WindowManager) mContext.getSystemService(
Context.WINDOW_SERVICE);
final Display display = windowManager.getDefaultDisplay();
final Point displaySize = new Point();
if (Build.VERSION.SDK_INT >= 17) {
display.getRealSize(displaySize);
} else if (Build.VERSION.SDK_INT >= 13) {
display.getSize(displaySize);
} else {
displaySize.set(display.getWidth(), display.getHeight());
}
final int smallestWidth = Math.min(displaySize.x, displaySize.y);
final int minSmallestWidthCascading = mContext.getResources().getDimensionPixelSize(
R.dimen.abc_cascading_menus_min_smallest_width);
final boolean enableCascadingSubmenus = smallestWidth >= minSmallestWidthCascading;
final MenuPopup popup;
if (enableCascadingSubmenus) {
popup = new CascadingMenuPopup(mContext, mAnchorView, mPopupStyleAttr,
mPopupStyleRes, mOverflowOnly);
} else {
popup = new StandardMenuPopup(mContext, mMenu, mAnchorView, mPopupStyleAttr,
mPopupStyleRes, mOverflowOnly);
}
// Assign immutable properties.
popup.addMenu(mMenu);
popup.setOnDismissListener(mInternalOnDismissListener);
// Assign mutable properties. These may be reassigned later.
popup.setAnchorView(mAnchorView);
popup.setCallback(mPresenterCallback);
popup.setForceShowIcon(mForceShowIcon);
popup.setGravity(mDropDownGravity);
return popup;
}
you will see that size of PopupMenu kind of hardcoded as per display size. So probably easy way is to check PopupMenu related source code and implement something similar, but with sizes which you'd like to have.

Trythis:
pwindow =
new PopupWindow(layoutt,LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,true);

Try to set minWidth in your style as below
<item name="android:minWidth">1000dp</item>

try this ,
inflater.inflate(R.layout.menu, menu);
or
menu.inflate(R.layout.popup_menu);

Make it translucent. I made same for pop up like this. Please check this one. May be it also work for you.
In your manifest:
<activity
android:name=".ActivityInviteFriend"
android:theme="#style/Theme.TransparentInfo">
</activity>
In style: main theme:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/LightappActionBarColor</item>

<item name="colorAccent">#color/btn_color</item>
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
</style>
and your custom theme:
<color name="semiTransparentBlack">#00000000</color>
<style name="Theme.TransparentInfo" parent="AppTheme">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#color/semiTransparentBlack</item>

Change style for AlertDialog lower grey panel

What style is causing the grey bar in the bottom of an AlertDialog?
Either I need to change the rest of the dialog to match the color or vice versa. I've tried modifying #android:buttonStyle and #android:buttonBarStyle. That helps but there's still some grey peeking out from the edges of the region.
Here are my current styles:
<style name="MyAlertDialog" parent="#android:style/Theme.Dialog">
<item name="#android:background">#FF000000</item>
<item name="#android:buttonBarStyle">#style/MyButtonBar</item>
</style>
<style name="MyButtonBar" parent="#android:style/ButtonBar">
<item name="#android:background">#FF000000</item>
</style>
And it looks like this:

Here is a working solution, based on Rod_Algonquin's idea of using a custom layout.
private void showCustomAlert (String message)
{
// build dialog
LayoutInflater inflater = getLayoutInflater();
View alertView = inflater.inflate (R.layout.custom_dialog, null);
AlertDialog.Builder builder = new AlertDialog.Builder (this, R.style.CustomAlertDialog);
builder.setView (alertView);
final AlertDialog alert = builder.create();
// message
((TextView)alertView.findViewById (R.id.message)).setText (message);
// ok button
alertView.findViewById (R.id.cancel).setOnClickListener (new View.OnClickListener()
{
#Override public void onClick(View v) { alert.dismiss(); }
});
// show
alert.show();
}
Here is a layout that works with this code:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#FF000000">
<TextView android:id="#+id/alertTitle"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="50dp"
android:gravity="center"
android:background="#android:color/black"
android:textColor="#android:color/white"
android:textAppearance="#android:style/TextAppearance.Large"
android:text="#string/custom_alert_title" />
<TextView android:id="#+id/message"
style="#android:attr/textAppearanceMedium"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="20dp"
android:background="#android:color/black"
android:textColor="#android:color/white"
android:textAppearance="#android:style/TextAppearance.Medium" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center"
android:background="#android:color/black"
android:measureWithLargestChild="true">
<Button android:id="#+id/cancel"
style="?android:attr/buttonBarButtonStyle"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:minHeight="50dp"
android:minWidth="100dp"
android:textSize="14sp"
android:text="#android:string/ok" />
</LinearLayout>
</LinearLayout>
Finally, here's the styles, from styles.xml, I referenced; you may not need them depending on your dialog coloring.
<style name="CustomAlertDialog" parent="#android:style/Theme.Dialog">
<item name="#android:background">#FF000000</item>
<item name="#android:buttonBarStyle">#style/CustomButtonBar</item>
</style>
<style name="CustomButtonBar" parent="#android:style/ButtonBar">
<item name="#android:background">#FF000000</item>
</style>

AlertDialog Theme: How to change item text color?

When I try to apply a standard theme to AlertDialog
AlertDialog.Builder builder = new AlertDialog.Builder(MyClass.this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
builder.setTitle("Change");
String[] info= this.getResources().getStringArray(R.array.info);
ArrayAdapter arrayAdapter = new ArrayAdapter(this, android.R.layout.select_dialog_singlechoice);
arrayAdapter.addAll(info);
builder.setSingleChoiceItems(arrayAdapter, ....
Result:
The note is that I have no problem with builder.setItems(...) since its text color is Black while the theme applied with builder.setSingleChoiceItems(...) has a White text color.
Any fast fix? Or any way to create a customized theme based on AlertDialog.THEME_DEVICE_DEFAULT_LIGHT ?
My customized style doesn't work as expected:
<style name="AlertDialogCustomTheme" android:parent="android:Theme.Dialog">
<item name="android:textColor">#7ABDFF</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<!--THE FOLLOWING ITEMS HAVE NOT EFFECT ... !! -->
<item name="android:layout_centerHorizontal">true</item>
<item name="android:layout_centerVertical">true</item>
<item name="android:textColorAlertDialogListItem">#A844BD</item>
<item name="android:itemBackground">#7ABDFF</item>
</style>
Update
#lopez answer is a complete solution, but I find a single line fix for my problem, a custom theme to be applied to the activity in manifest:
<style name="MyTheme">
<item name="android:textColorAlertDialogListItem">#android:color/black</item>
</style>

If anyone happens to read this, and is using the Suport library Alert Dialogs and wants to change the text color of list items then drop the android: part, like so:
<item name="textColorAlertDialogListItem">#color/your_color</item>

Personally, I use the android Dialog but I use a custom layout for that match the design of my application.
Here is an example:
new AlertDialog.Builder(context)
.setView(inflater.inflate(R.layout.dialog_delete_contact, null))
.setPositiveButton(context.getResources().getString(android.R.string.ok).toUpperCase(), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// YOUR TREATMENT
}
})
.setNegativeButton(context.getResources().getString(android.R.string.cancel).toUpperCase(), null)
.show();
Layout:
<LinearLayout 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/GrayLight"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:background="#color/Black"
android:gravity="center"
android:orientation="horizontal"
tools:ignore="DisableBaselineAlignment" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:layout_weight="2"
android:gravity="center"
android:orientation="horizontal" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/app_name"
android:fitsSystemWindows="true"
android:padding="10dip"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:layout_marginRight="20dp"
android:layout_weight="0.5"
android:gravity="center"
android:orientation="horizontal" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/remove_contact"
android:textColor="#color/White"
android:textSize="20sp"
android:textStyle="bold"
tools:ignore="HardcodedText" />
</LinearLayout>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center"
android:orientation="vertical"
tools:ignore="DisableBaselineAlignment" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="10dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:paddingTop="20dp"
android:text="#string/ask_remove_contact"
android:textSize="15sp"
tools:ignore="HardcodedText" />
</LinearLayout>
Result in picture:
To avoid rewriting the code every time here is a utility class :
public class MyDialog {
public static Builder create(final Context context, final LayoutInflater layoutInflater, final String title, final String content) {
View view = layoutInflater.inflate(R.layout.generic_dialog, null);
((TextView)view.findViewById(R.id.textViewTitleDialog)).setText(title);
((TextView)view.findViewById(R.id.textViewContentDialog)).setText(content);
return new AlertDialog.Builder(context).setView(view);
}
}
And an example of using :
AlertDialog.Builder myDialog = MyDialog.create(this, getLayoutInflater(), "Quitter ECOLEMS", "Voulez-vous vraiment quitter l'application?");
myDialog.setPositiveButton("Oui", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// YOUR TREATMENT
}
})
.setNegativeButton("Non", null)
.show();
I hope you have helped!

What works for me
<style name="AlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:textColor">#color/text</item>
<item name="android:background">#color/background</item>
<item name="android:textColorPrimary">#color/text</item>
<item name="textColorAlertDialogListItem">#color/text</item>
</style>

This is what worked for me for every color on my dialog:
<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">#00ffff</item>
<!-- Used for the title and text -->
<item name="android:textColor">#00ff00</item>
<item name="android:textColorAlertDialogListItem">#ffff00</item>
<item name="android:textColorSecondary">#ff00ff</item>
<!-- Used for the background -->
<item name="android:background">#3a3a3c</item>
</style>

AlertDialog.Builder builder = new AlertDialog.Builder(MyClass.this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
builder.setTitle("Change");
String[] info= this.getResources().getStringArray(R.array.info);
ArrayAdapter arrayAdapter = new ArrayAdapter(this, android.R.layout.select_dialog_singlechoice);
arrayAdapter.addAll(info);
builder.setSingleChoiceItems(arrayAdapter, ....**change this line to**
builder.setSingleChoiceItems(info,0,null);

RelativeLayout.ALIGN_PARENT_RIGHT not work

RelativeLayout.ALIGN_PARENT_RIGHT not work. (((
it is my Android-Function.
She added new message to a stage.
I do not understand.
Why my code does not work correctly
private void addMessageToStage(Message message) {
LinearLayout scrollChatMessagesOutput = (LinearLayout) findViewById(R.id.chatMessagesOutput);
LayoutInflater layoutInflater = getLayoutInflater();
View view = layoutInflater.inflate(R.layout.chat_single_message, null, false);
TextView messageTextView = (TextView) view.findViewById(R.id.singleChatMessageTextView);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
if (messagesAlignId % 2 == 0) {
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
messageTextView.setBackgroundResource(R.drawable.chat_input_message_shape);
} else {
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
messageTextView.setBackgroundResource(R.drawable.chat_output_message_shape);
}
messageTextView.setText(Html.fromHtml("<b><u>" + message.getMessage() + "<font color=\"#cccccc\" size=\"4px\">" + "\n" + message.getTime() + "</font></b></u>"));
RelativeLayout messageAlignLayout = new RelativeLayout(this);
messageAlignLayout.addView(view, params);
scrollChatMessagesOutput.addView(messageAlignLayout);
}
It is chat_single_message.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/chatMessage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1.0" >
<TextView
android:id="#+id/singleChatMessageTextView"
style="#style/singleChatMessageTextStyle" />
</LinearLayout>
It is singleChatMessageTextStyle.
<style name="singleChatMessageTextStyle" parent="#android:style/TextAppearance.Small">
<item name="android:layout_width">0dp</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_marginBottom">10dp</item>
<item name="android:layout_marginLeft">5dp</item>
<item name="android:layout_marginRight">5dp</item>
<item name="android:padding">3dp</item>
<item name="android:layout_weight">0.7</item>
<item name="android:textColor">#000000</item>
<item name="android:typeface">sans</item>
<item name="android:textSize">12sp</item>
</style>

Consider using two different layouts:
A layout with the text on the left, chat_single_message_left.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/chatMessage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1.0" >
<TextView
android:id="#+id/singleChatMessageTextView"
style="#style/singleChatMessageTextStyle" />
<View
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.3"
android:visibility="invisible" />
</LinearLayout>
A similar layout with the text on the right, chat_single_message_right.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/chatMessage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1.0" >
<View
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.3"
android:visibility="invisible" />
<TextView
android:id="#+id/singleChatMessageTextView"
style="#style/singleChatMessageTextStyle" />
</LinearLayout>
And you should use a ListView to display each message rather than a ScrollView, ListView's are much faster for big conversations.
