I want to slide a PopupWindow from the bottom of the screen to some point above it, say center.
I have the following logic so far
val inflater = getSystemService(LAYOUT_INFLATER_SERVICE) as LayoutInflater
val popupView: View = inflater.inflate(R.layout.popup_window, null)
val width = LinearLayout.LayoutParams.WRAP_CONTENT
val height = LinearLayout.LayoutParams.WRAP_CONTENT
val focusable = true // lets taps outside the popup also dismiss it
val popupWindow = PopupWindow(popupView, width, height, focusable)
val slide = Slide()
slide.apply {
duration = 300
slideEdge = Gravity.BOTTOM
}
view?.doOnAttach {
popupWindow.isFocusable = true
popupWindow.enterTransition = slide
popupWindow.exitTransition = slide
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0)
}
I am able to slide the window between its width. So what this does is that the sliding happens from -w/2 where w is the width of the window and ends at w/2. Which maybe expected since the position of the window is set as 0, 0. However I want the sliding to happen between 2 specific points. Like the sliding should start from the bottom of the screen and it should continue to slide till it reaches the coordinate 0,0.
I found a workaround by expanding the width of the window to the portion below 0,0 but that cause the views below it to not be clickable. So this doesn't work in my case. Is there a way to do this sliding? Thanks!
My popup window should be auto dismissed when click outside. I already read this topic, and have set background drawable to the window. Here is my code:
protected int showPopupWindow(final int popupWidth) {
hideCalendarCellPopupWindow();
final LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(LAYOUT_INFLATER_SERVICE);
final View popupView = inflater.inflate(R.layout.popup_calendar_cell, null);
mCalendarCellPopupWindow = new PopupWindow(popupView, popupWidth, ViewGroup.LayoutParams.WRAP_CONTENT);
mCalendarCellPopupWindow.setBackgroundDrawable(new ColorDrawable(Color.WHITE));
mCalendarCellPopupWindow.setOutsideTouchable(true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
mCalendarCellPopupWindow.setElevation(...);
}
mCalendarCellPopupWindow.showAtLocation(....);
}
private hideCalendarCellPopupWindow() {
if (mCalendarCellPopupWindow != null) {
mCalendarCellPopupWindow.dismiss();
mCalendarCellPopupWindow = null;
}
}
A problem have appeared on Android 10, as you can touch outside of the phone screen and slide the finger inside the screen, meanwhile "recent apps" could be shown with such gesture.
So my issue is when I slide the finger from the bottom to the top a little bit and than go back to the bottom - popup window is not dismissed, moreover it cannot be dissmissed no more, as its property isShowing() returns false. I have tried to call popupWindow.dismiss() method inside onPause() but it is not called as well in such situation.
This screencast could explain the issue more precies: https://youtu.be/w2cQMvFMYkk
What could be the workaround?
If you want to dismiss your popup outside, you may set as following:
popupWindow.setFocusable(true);
popupWindow.setTouchable(true);
popupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
popupWindow.setOutsideTouchable(true);
popupWindow.update();
Currently my popup is overlapping other views. setElevation(0) changes nothing. setOverlapAnchor(false) and setAttachedInDecor(true) also don't help much. Below is the code I have used. I need the popup to be located under navigation drawer
private fun showPopup(anchorView: View) {
PopupWindow(
LayoutInflater.from(activity).inflate(
R.layout.popup_layout,
null
),
100,
100,
false
)
.apply {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
view?.elevation = 0f
contentView.elevation = 0f
elevation = 0f
}
isTouchable = false
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
isAttachedInDecor = true
}
PopupWindowCompat.setOverlapAnchor(this, false)
PopupWindowCompat.showAsDropDown(this, anchorView, 0, 0, Gravity.NO_GRAVITY)
}
}
PopupWindow is a window. Your navigation drawer is located on another window with its own view hierarchy.
Its like this:
-- activity
---- window1
------ viewhierarchy
--------NavigationDrawer
---- window2
------ popup
What you want is not possible using PopupWindow.
One possible work-around is to hide & show the popup when navigation is opened and closed. Here's the callback:
https://developer.android.com/reference/android/support/v4/widget/DrawerLayout.DrawerListener.html#ondrawerstatechanged
Or you may add a view as popup by yourself and take care of the positioning and gravity.
Last but not least, check out these libraries as they may have what you want. They work with view so you may manage it the way you want.

I have studied many questions and answers in Stackoverflow, then I made a dummy function, that I run after a click in my app.
Here is the code:
fun openDialog(cx: Context) {
val alertDialog = Dialog(cx)
var linLayout = LinearLayout(cx)
linLayout.setOrientation(LinearLayout.VERTICAL);
// Set width, height and weight
linLayout.layoutParams = LinearLayout.LayoutParams(500,1000,1F)
// top and left position
linLayout.x = 0F
linLayout.y = 0F
val title = TextView(cx); // dummy view 1
title.setText("Custom Dialog 1")
title.setTextColor(Color.BLACK)
title.setTextSize(20F)
linLayout.addView(title) // add in layout
val msg = TextView(cx) // dummy view 2
msg.setText("Custom Dialog Box 2")
msg.setTextColor(Color.RED)
msg.setTextSize(10F)
linLayout.addView(msg) // add in layout
alertDialog.setContentView(linLayout) // Add the layout in Dialog
alertDialog.show(); // Show the dialog with layout
}
What I get? A proper dialog, but in the middle of the screen with width and height defined by the content. I also try to use the windows linked to the custom dialog without success.
val wlp = win.attributes
wlp.apply {
x = 0
y = 0
height = 1000
width = 500
}
win.attributes = wlp
No changes. However wlp.gravity = Gravity.BOTTOM works, but it's not enough for me. A also try to use win.setLayout(1000,500) without success
The Android documentation states:
Set the width and height layout parameters of the window. The default
for both of these is MATCH_PARENT; you can change them to WRAP_CONTENT
or an absolute value to make a window that is not full-screen.
Why can’t I resize and position the layout that I assign to my dialog?
Has somebody a hint?
The cell phone screen:
Update
I've got to change the position of dialog using
wlp.gravity = Gravity.TOP or Gravity.LEFT
wlp.x = 100 // Relative to left
wlp.y = 200 // relative to top
I keep trying to figure out how to change the width and height.
Set the layout params for the view you're inflating when you set the content :
this line :
alertDialog.setContentView(linLayout)
should be :
alertDialog.setContentView(linLayout, LinearLayout.LayoutParams(500,1000,1F))
You can also remove the explicit setting of the params for the LinearLayout
I would like to be able to either blur or dim the background when I show my popup window using popup.showAtLocation, and unblur/dim the background when popup.dismiss is called.
I have tried applying layout params FLAG_BLUR_BEHIND and FLAG_DIM_BEHIND to my activity, but this appears to just blur and dim the background as soon my app is started.
How can I do blurring/dimming just with popups?
The question was about the Popupwindow class, yet everybody has given answers that use the Dialog class. Thats pretty much useless if you need to use the Popupwindow class, because Popupwindow doesn't have a getWindow() method.
I've found a solution that actually works with Popupwindow. It only requires that the root of the xml file you use for the background activity is a FrameLayout. You can give the Framelayout element an android:foreground tag. What this tag does is specify a drawable resource that will be layered on top of the entire activity (that is, if the Framelayout is the root element in the xml file). You can then control the opacity (setAlpha()) of the foreground drawable.
You can use any drawable resource you like, but if you just want a dimming effect, create an xml file in the drawable folder with the <shape> tag as root.
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#000000" />
</shape>
(See http://developer.android.com/guide/topics/resources/drawable-resource.html#Shape for more info on the shape element).
Note that I didn't specify an alpha value in the color tag that would make the drawable item transparent (e.g #ff000000). The reason for this is that any hardcoded alpha value seems to override any new alpha values we set via the setAlpha() in our code, so we don't want that.
However, that means that the drawable item will initially be opaque (solid, non-transparent). So we need to make it transparent in the activity's onCreate() method.
Here's the Framelayout xml element code:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainmenu"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:foreground="#drawable/shape_window_dim" >
...
... your activity's content
...
</FrameLayout>
Here's the Activity's onCreate() method:
public void onCreate( Bundle savedInstanceState)
{
super.onCreate( savedInstanceState);
setContentView( R.layout.activity_mainmenu);
//
// Your own Activity initialization code
//
layout_MainMenu = (FrameLayout) findViewById( R.id.mainmenu);
layout_MainMenu.getForeground().setAlpha( 0);
}
Finally, the code to dim the activity:
layout_MainMenu.getForeground().setAlpha( 220); // dim
layout_MainMenu.getForeground().setAlpha( 0); // restore
The alpha values go from 0 (opaque) to 255 (invisible).
You should un-dim the activity when you dismiss the Popupwindow.
I haven't included code for showing and dismissing the Popupwindow, but here's a link to how it can be done: http://www.mobilemancer.com/2011/01/08/popup-window-in-android/
Since PopupWindow just adds a View to WindowManager you can use updateViewLayout (View view, ViewGroup.LayoutParams params) to update the LayoutParams of your PopupWindow's contentView after calling show..().
Setting the window flag FLAG_DIM_BEHIND will dimm everything behind the window. Use dimAmount to control the amount of dim (1.0 for completely opaque to 0.0 for no dim).
Keep in mind that if you set a background to your PopupWindow it will put your contentView into a container, which means you need to update it's parent.
With background:
PopupWindow popup = new PopupWindow(contentView, width, height);
popup.setBackgroundDrawable(background);
popup.showAsDropDown(anchor);
View container = (View) popup.getContentView().getParent();
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams) container.getLayoutParams();
// add flag
p.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.3f;
wm.updateViewLayout(container, p);
Without background:
PopupWindow popup = new PopupWindow(contentView, width, height);
popup.setBackgroundDrawable(null);
popup.showAsDropDown(anchor);
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams) contentView.getLayoutParams();
// add flag
p.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.3f;
wm.updateViewLayout(contentView, p);
Marshmallow Update:
On M PopupWindow wraps the contentView inside a FrameLayout called mDecorView. If you dig into the PopupWindow source you will find something like createDecorView(View contentView).The main purpose of mDecorView is to handle event dispatch and content transitions, which are new to M. This means we need to add one more .getParent() to access the container.
With background that would require a change to something like:
View container = (View) popup.getContentView().getParent().getParent();
Better alternative for API 18+
A less hacky solution using ViewGroupOverlay:
1) Get a hold of the desired root layout
ViewGroup root = (ViewGroup) getWindow().getDecorView().getRootView();
2) Call applyDim(root, 0.5f); or clearDim()
public static void applyDim(#NonNull ViewGroup parent, float dimAmount){
Drawable dim = new ColorDrawable(Color.BLACK);
dim.setBounds(0, 0, parent.getWidth(), parent.getHeight());
dim.setAlpha((int) (255 * dimAmount));
ViewGroupOverlay overlay = parent.getOverlay();
overlay.add(dim);
}
public static void clearDim(#NonNull ViewGroup parent) {
ViewGroupOverlay overlay = parent.getOverlay();
overlay.clear();
}
In your xml file add something like this with width and height as 'match_parent'.
<RelativeLayout
android:id="#+id/bac_dim_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#C0000000"
android:visibility="gone" >
</RelativeLayout>
In your activity oncreate
//setting background dim when showing popup
back_dim_layout = (RelativeLayout) findViewById(R.id.share_bac_dim_layout);
Finally make visible when you show your popupwindow and make its visible gone when you exit popupwindow.
back_dim_layout.setVisibility(View.VISIBLE);
back_dim_layout.setVisibility(View.GONE);
Another trick is to use 2 popup windows instead of one. The 1st popup window will simply be a dummy view with translucent background which provides the dim effect. The 2nd popup window is your intended popup window.
Sequence while creating pop up windows:
Show the dummy pop up window 1st and then the intended popup window.
Sequence while destroying:
Dismiss the intended pop up window and then the dummy pop up window.
The best way to link these two is to add an OnDismissListener and override the onDismiss() method of the intended to dimiss the dummy popup window from their.
Code for the dummy popup window:
fadepopup.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="#+id/fadePopup"
android:background="#AA000000">
</LinearLayout>
Show fade popup to dim the background
private PopupWindow dimBackground() {
LayoutInflater inflater = (LayoutInflater) EPGGRIDActivity.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View layout = inflater.inflate(R.layout.fadepopup,
(ViewGroup) findViewById(R.id.fadePopup));
PopupWindow fadePopup = new PopupWindow(layout, windowWidth, windowHeight, false);
fadePopup.showAtLocation(layout, Gravity.NO_GRAVITY, 0, 0);
return fadePopup;
}
I've found a solution for this
Create a custom transparent dialog and inside that dialog open the popup window:
dialog = new Dialog(context, android.R.style.Theme_Translucent_NoTitleBar);
emptyDialog = LayoutInflater.from(context).inflate(R.layout.empty, null);
/* blur background*/
WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();
lp.dimAmount=0.0f;
dialog.getWindow().setAttributes(lp);
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
dialog.setContentView(emptyDialog);
dialog.setCanceledOnTouchOutside(true);
dialog.setOnShowListener(new OnShowListener()
{
#Override
public void onShow(DialogInterface dialogIx)
{
mQuickAction.show(emptyDialog); //open the PopupWindow here
}
});
dialog.show();
xml for the dialog(R.layout.empty):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent" android:layout_width="match_parent"
style="#android:style/Theme.Translucent.NoTitleBar" />
now you want to dismiss the dialog when Popup window dismisses. so
mQuickAction.setOnDismissListener(new OnDismissListener()
{
#Override
public void onDismiss()
{
if(dialog!=null)
{
dialog.dismiss(); // dismiss the empty dialog when the PopupWindow closes
dialog = null;
}
}
});
Note: I've used NewQuickAction plugin for creating PopupWindow here. It can also be done on native Popup Windows
For me, something like Abdelhak Mouaamou's answer works, tested on API level 16 and 27.
Instead of using popupWindow.getContentView().getParent() and casting the result to View (which crashes on API level 16 cause there it returns a ViewRootImpl object which isn't an instance of View) I just use .getRootView() which returns a view already, so no casting required there.
Hope it helps someone :)
complete working example scrambled together from other stackoverflow posts, just copy-paste it, e.g., in the onClick listener of a button:
// inflate the layout of the popup window
LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
if(inflater == null) {
return;
}
//View popupView = inflater.inflate(R.layout.my_popup_layout, null); // this version gives a warning cause it doesn't like null as argument for the viewRoot, c.f. https://stackoverflow.com/questions/24832497 and https://stackoverflow.com/questions/26404951
View popupView = View.inflate(MyParentActivity.this, R.layout.my_popup_layout, null);
// create the popup window
final PopupWindow popupWindow = new PopupWindow(popupView,
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT,
true // lets taps outside the popup also dismiss it
);
// do something with the stuff in your popup layout, e.g.:
//((TextView)popupView.findViewById(R.id.textview_popup_helloworld))
// .setText("hello stackoverflow");
// dismiss the popup window when touched
popupView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
popupWindow.dismiss();
return true;
}
});
// show the popup window
// which view you pass in doesn't matter, it is only used for the window token
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
//popupWindow.setOutsideTouchable(false); // doesn't seem to change anything for me
View container = popupWindow.getContentView().getRootView();
if(container != null) {
WindowManager wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams)container.getLayoutParams();
p.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.3f;
if(wm != null) {
wm.updateViewLayout(container, p);
}
}
Maybe this repo will help for you:BasePopup
This is my repo, which is used to solve various problems of PopupWindow.
In the case of using the library, if you need to blur the background, just call setBlurBackgroundEnable(true).
See the wiki for more details.（Language in zh-cn）
BasePopup:wiki
findViewById(R.id.drawer_layout).setAlpha((float) 0.7);
R.id.drawer_layout is the id of the layout of which you want to dim the brightness.
You can use android:theme="#android:style/Theme.Dialog" to do that.
Create an activity and in your AndroidManifest.xml define the activity as:
<activity android:name=".activities.YourActivity"
android:label="#string/your_activity_label"
android:theme="#android:style/Theme.Dialog">
ok, so i follow uhmdown's answer for dimming background activity when pop window is open. But it creates problem for me. it was dimming activity and include popup window (means dimmed-black layered on both activity and popup also, it can not be separate them).
so i tried this way,
create an dimming_black.xml file for dimming effect,
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#33000000" />
</shape>
And add as background in FrameLayout as root xml tag, also put my other controls in LinearLayout like this layout.xml
<?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"
android:orientation="vertical"
android:background="#drawable/ff_drawable_black">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="bottom"
android:background="#color/white">
// other codes...
</LinearLayout>
</FrameLayout>
at last i show popup on my MainActivity with some extra parameter set as below.
//instantiate popup window
popupWindow = new PopupWindow(viewPopup, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT, true);
//display the popup window
popupWindow.showAtLocation(layout_ff, Gravity.BOTTOM, 0, 0);
Result:
it works for me, also solved problem as commented by BaDo. With this Actionbar also can be dimmed.
P.s i am not saying uhmdown's is wrong. i learnt form his answer and try to evolve for my problem. I also confused whether this is a good way or not.
Any suggestions is also appreciated also sorry for my bad English.
Since You are trying to pop up your dialog window by blurring the background screen, You must use this set of lines. You need to fetch the dialog attributes first, then set up some alpha values for the dialog attributes.
Now, your dialog with blur background is ready. But the important factor is to set a Flag FLAG_DIM_BEHIND for the window.
Now the result is yours. Hope it will helpful for someone...
WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();
lp.dimAmount=0.6f;
dialog.getWindow().setAttributes(lp);
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
This code work
pwindo = new PopupWindow(layout, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);
pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);
pwindo.setOutsideTouchable(false);
View container = (View) pwindo.getContentView().getParent();
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams) container.getLayoutParams();
p.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.3f;
wm.updateViewLayout(container, p);
