Fragment gets no width and no height



enter image description here



The Dialog that you see is a activity with a Dialog theme. The layout inside it is
a fragment that should match its width and height. It is added programatically using the FragmentTransaction class.


FragmentTransaction



The issue is that the fragment layout gets squished together and looks awful. I have used match_parent in the xml on both the fragments layout and activitys.


match_parent



How do i stop the dialog from being squished together and have a more "natural" size?

Most of times I faced this issue is when I used a wrong Theme for Dialogs. Put the pointer/cursor over the declared custom style and check if it has "android:windowMinWidthMajor" and "android:windowMinWidthMinor" attributes as explained here: stackoverflow.com/questions/20199118/… Without these parameters the Dialog shrinks itselfs to minimum size if the MATCH_PARENT attribute is used in the main Root of its contained View. Try even to use WRAP_CONTENT in the main contained Root View

Customizing the height and width of alert dialog android. Following is the code


WindowManager.LayoutParams params = new WindowManager.LayoutParams();

params.copyFrom(alertDialog.getWindow().getAttributes());
params.width = 100;
params.height = 400;
params.x=-190;
params.y=80;
alertDialog.getWindow().setAttributes(params);



Not sure but hope it will work.

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12...

Creating a leaderboard in HTML/JS

Image
Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
