My app is a full screen app. It goes full width and does not show a status bar, uses CutoutMode and hides controls like (Home and Back). This also works well.
However, when I create a PopUpWindow, these settings don't seem to take effect. See the following image:
I would have expected that the quadrangles marked in red on the left and right would also be in the corresponding shade of gray.
My code to initialize the PopUp Window looks like this:
val inflater =
view.context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as? LayoutInflater
?: return
// Inflate a custom view using layout inflater
val popUpView = inflater.inflate(R.layout.view_change_name, null)
//popUpView.animation = AnimationUtils.loadAnimation(view.context, R.anim.fade_in_animation)
// Initialize a new instance of popup window
val popupWindow = PopupWindow(
popUpView, // Custom view to show in popup window
LinearLayout.LayoutParams.MATCH_PARENT, // Width of popup window
LinearLayout.LayoutParams.MATCH_PARENT, // Window height
true
)
popupWindow.animationStyle = R.style.PopUpWindowAnimation
popupWindow.isFocusable = true
popupWindow.isOutsideTouchable = true
popupWindow.update(
0,
0,
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT
)
//Set the location of the window on the screen
popupWindow.showAtLocation(view, Gravity.BOTTOM, 0, 0)
My method to get the full screen in my activity works like this.
fun Activity.fullscreen() {
with(WindowInsetsControllerCompat(window, window.decorView)) {
systemBarsBehavior = WindowInsetsControllerCompat.BEHAVIOR_SHOW_BARS_BY_SWIPE
hide(Type.systemBars())
}
}
So my idea was to get a decorView in the PopUpWindow. But I think the PopUpWindow has not a decorView. I'm running out of ideas. Does anyone have an approach or solution?
How stupid. After I post this question I found an answer.
Use
popupWindow.isClippingEnabled = false
Documentation
#param enabled false if the window should be allowed to extend outside of the screen
I have tried using a code that is working fine except when I click on the last or end rows of the recyclerview, the popupWindow opens offscreen. Is there any way to show the popupWindow upSide of the view for end rows of the recyclerview.
Here is the code I am using:
public void showPopup(View v, int _pos) {
LayoutInflater layoutInflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup_row_appointment_option, null);
popupWindow = new PopupWindow(
popupView,
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setBackgroundDrawable(new BitmapDrawable());
popupWindow.setFocusable(true);
popupWindow.setOutsideTouchable(true);
popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
#Override
public void onDismiss() {
//TODO do sth here on dismiss
}
});
popupWindow.showAsDropDown(v, v.getScrollX(), v.getScrollY());
tv_view_profile = (TextView) popupView.findViewById(R.id.tv_view_profile);
tv_view_profile.setOnClickListener(this);
}
I would suggest you to go for PopupMenu which accepts AnchorView -> with the use of that we can get the exact position where we want to show popup -> you can pass AnchroView as View (The three dot imageview)
Here is the great example of it :
https://www.javatpoint.com/android-popup-menu-example
And also please use Appcompat version to get Material touch in menu.
Ok with custom layout you can go with your regular flow with minor changes --
popup.showAtLocation(anchorView, Gravity.BOTTOM, 0,
anchorView.getBottom() - 60);
this is just an example for bottom gravity. You can set gravity and margin according to your code.
anchorView = the view where you want to show this popup. Try this and let me know if you have any query.
I am trying to make something like a pop-up window, that would appear when clicked on a view in a fragment. I want this pop-up window or whatever, to not make the fragment dark, like a Dialog Fragment does.
And I also want the pop up to be positioned where the view is clicked.
Would be good if it has its own activity and layout so I can do some custom changes in it.
Can you plese show me some sample code?
The following should work perfect in accordance with your specification. Call this method from inside onClick(View v) of OnClickListener assigned to the View:
public void showPopup(View anchorView) {
View popupView = getLayoutInflater().inflate(R.layout.popup_layout, null);
PopupWindow popupWindow = new PopupWindow(popupView,
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
// Example: If you have a TextView inside `popup_layout.xml`
TextView tv = (TextView) popupView.findViewById(R.id.tv);
tv.setText(....);
// Initialize more widgets from `popup_layout.xml`
....
....
// If the PopupWindow should be focusable
popupWindow.setFocusable(true);
// If you need the PopupWindow to dismiss when when touched outside
popupWindow.setBackgroundDrawable(new ColorDrawable());
int location[] = new int[2];
// Get the View's(the one that was clicked in the Fragment) location
anchorView.getLocationOnScreen(location);
// Using location, the PopupWindow will be displayed right under anchorView
popupWindow.showAtLocation(anchorView, Gravity.NO_GRAVITY,
location[0], location[1] + anchorView.getHeight());
}
The comments should explain this well enough. anchorView is the v from onClick(View v).
I have to show a popupwindow. If i show it in click event of the ImageView, Then i call dismiss it hides. But when i show it in Touch event of ImageView, then dismiss event calls, but the popup not hides. What are the reasons for this error?. How can i solve it?
The code i used to show popup window is
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels; //320
CabotMessageHandler.printConsole("width of screen"+width);
//show Popup
LayoutInflater inflater = (LayoutInflater)
this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
popupView=inflater.inflate(R.layout.gallerytoppopup, null, false);
pw = new PopupWindow(
popupView,
width,
30,
true);
// The code below assumes that the root container has an id called 'main'
pw.setAnimationStyle(R.anim.popupanimation);
pw.showAtLocation(this.findViewById(R.id.webview), Gravity.TOP, 0, 30);
Finally i find out the problem. The touch event calls twice, and two popups created. That was the reason to not hide the Popup when dismiss called.(One popup hides and other remains there).
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);
