How do you get a layout that contains an element in the Android?

Bogopo last edited by

The Android question is, there's a button, and we need to get a layout where it is. How do you do that? Note: Id is not possible because the buttons are added through inflate and should be obtained in the Click method.

For any parent View He has a method. getParent()♪ The result they return must be downloaded. ViewParent to an heir ViewGroup:

fixed positioning itself on the viewing window. The view screen is always fixed, so you get the effect you're doing. But every time you "initiate" any breadth, it'll match the search file.I can decide with help. JS or give a fixed width through CSSfunction fixedBlock(){ var parentwidth = $("div.black").width(); $("form.fixed").css('width', function(){ return parentwidth }); }; $(document).ready(function(){ fixedBlock(); }); $( window ).resize(function() { fixedBlock(); });.red { background: red } .black { background: black; padding: 0 !important } .green { background: green } div { padding: 10px; height: 100vh } form { background: blue; padding: 5px; position: fixed; bottom: 0; }<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" /> <div class="container-fluid"> <div class="row"> <div class="col col-xl-3 col-lg-3 col-md-12 col-sm-12 col-12 red"> Текст </div> <div class="col col-xl-6 col-lg-6 col-md-12 col-sm-12 col-12 black"> Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text <form class="fixed">Форма ввода</form> </div> <div class="col col-xl-3 col-lg-3 col-md-12 col-sm-12 col-12 green"> Текст </div> </div> </div>

It's simple, according to the error report, class. Elements does not contain a default designer, so it is required to transmit all the required parameters, such as name, content, date of creation (see the designer to understand what this class requires), i.e. your code must be about this, @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(r.layout.activity_main); Toolbar toolbar = findViewById(r.id.toolbar); setSupportActionBar(toolbar); listTasks = findViewById(r.id.list); ContentList(); FloatingActionButton fab = findViewById(R.id.fab); fab.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Elements elements = new Elements("name1", "text1", new Date()); // может быть что-то еще после Date на скрине непонятно Elements.setName(getResources().getString(r.string.new_document)); showDocument(elements); startActivity(new Intent(mainActivity.this, Main2Activity.class)); } }); } P. S. It's very unsupervised to use the wrong names of variables. (The Java stash code should start with a small letter, large classes, and constants only with large letters). Otherwise, other software players get confused and using words like T<T> T = new T<T>(); You'll easily confuse even the compilator.

About this In the processors, we can read: https://learn.javascript.ru/introduction-browser-events ♪But to keep the processors on all the elements, better use it. https://learn.javascript.ru/event-delegation and, to this end, place the elements in the container (if they are not in the appropriate element).document.querySelector('#switches').addEventListener('click', function(event) { const target = event.target; if (target.className !== 'form_switch') return; console.log(target.innerText); });<div id="switches"> <div class="form_switch"> Пункт 1 </div> <div class="form_switch"> Пункт 2 </div> </div>

The problem is, key It's null, then when you do .child(key) It can't go wrong with that reference, check where you put the value and if you're assigning it inside your onCreate() before I call productDetail(key)

When you use floats your layout is unchecked.It will happen that the container float be no smaller than your child, use overflow: hidden. It will focus the element within a box float you can use foexbox: display: flex; align-items: center; justify-content: center in the father. Or else, use the position: position: absolute; left, top, right, bottom: 0; margin: auto so it would focus the content easily.I hope this is the solution to your problem, because the truth didn't understand very well.

How do you change Button from Listview through the adapter?

Adapter's got a view to display on the list when the list requests the display point he needs, and the view in the adapter will not be displayed until the list again requests this position, it may not be very soon.In order to update the website after it was set up, you need access to his already created adapter view, it's decided not through the redefinition of getView in the adapter, but through access to the right view of the outside, then you get the button and change the background.int visiblePosition = listView.getFirstVisiblePosition(); View v = listView.getChildAt(position - visiblePosition); Button button = (Button) v.findViewById(R.id.button);//id кнопки в разметке айтема button.setBackground(background);// вставить свое значение для фона Don't forget to update the data on the model.The second option of addressing your question may be the following pattern:1. Modify the required value in the collection of objects (models) to be transferred to the adapter 2. Doing. listView.notifyDataSetChanged(); - it'll make the adapter re-establish the view of the list webs using current data.Which is the preferred way to decide, depending on the specific conditions of implementation, the second method, naturally, is more loaded for the device and is usually used when many (all) lists are updated once--- it affects the contents of the entire list.

The simplest option is to mark your item. RecyclerView Set the attributes:android:background="?selectableItemBackground" Here's a little example:<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="@dimen/tile_height_medium_item" android:background="?selectableItemBackground"> ... </androidx.constraintlayout.widget.ConstraintLayout> If you need a more delicate setting, you need your hands to build. background♪ Here's a little example:<?xml version="1.0" encoding="utf-8"?> <ripple xmlns:android="http://schemas.android.com/apk/res/android" android:color="?android:attr/colorControlHighlight"> <item android:id="@android:id/mask"> <shape android:shape="rectangle"> <corners android:radius="8dp" /> <solid android:color="@color/core_black" /> </shape> </item> <item> <selector> <item android:state_enabled="false"> <shape android:shape="rectangle"> <solid android:color="@color/transparent" /> <corners android:radius="8dp" /> </shape> </item> <item> <shape android:shape="rectangle"> <solid android:color="@color/background_system1" /> <corners android:radius="8dp" /> </shape> </item> </selector> </item> </ripple> The essence of this code is that you write to every state your attributes. View inside <selector>♪ Like this. android:state_enabled="false" and non-contracting status (lower) used in all other cases. You can write an unrestricted ring. They can also be combined, for example:android:state_enabled="false" android:state_pressed="true" After what you're just asking for. drawable in your background View:android:background="@drawable/button_round_n7_background"

here you have a solution using the operator -cmatch. In this case, in powershell there are operators -match -imatch and -cmatch which distinguish between upper and lowercase, etc. In this case, using cmatch and regular pattern [A-Z] It seems enough.This is the note in the documentation: Traditionally, regular expressions are case sensitive by default. This is true for the .NET framework too. However, it is not true in PowerShell. -match and -replace are case insensitive, as are -imatch and -ireplace. For case sensitive matching, use -cmatch and -creplace. I recommend that you always use the “i” or “c” prefix to avoid confusion regarding case sensitivity.That is, in the case of Powershell, it seems that -match and -replace are case Insensitive, and therefore you must use cmatch https://www.regular-expressions.info/powershell.html Here the example script:#Creamos el objeto array $ARRAY = @("a:1" , "a:2", "a:3", "A:4", "a:5") Write-Output "Primer array $($ARRAY)" $detected = $false; #Lo recorremos, y utilizamos el operador -match For ($i=0; $i -lt $ARRAY.count ; $i++) { if( $ARRAY[$i] -cmatch "[A-Z]" ) { Write-Output "La posición con mayúsculas es $($i+1)" Write-Output "El valor recuperado es $($ARRAY[$i])" Write-Output "La letra localizada es $($Matches.Values[0])" $detected = $true; } } if(-Not $detected) {Write-Output "El Array no contiene mayúsculas"} $ARRAY = @("A:4","a:1" , "a:2", "a:3", "a:5") Write-Output "Segundo array $($ARRAY)" $detected = $false; For ($i=0; $i -lt $ARRAY.count ; $i++) { if( $ARRAY[$i] -cmatch "[A-Z]" ) { Write-Output "La posición con mayúsculas es $($i+1)" Write-Output "El valor recuperado es $($ARRAY[$i])" Write-Output "La letra localizada es $($Matches.Values[0])" $detected = $true; } } if(-Not $detected) {Write-Output "El Array no contiene mayúsculas"} $ARRAY = @("a:4","a:1" , "a:2", "a:3", "a:5") Write-Output "Tercer array $($ARRAY)" $detected = $false; For ($i=0; $i -lt $ARRAY.count ; $i++) { if( $ARRAY[$i] -cmatch "[A-Z]" ) { Write-Output "La posición con mayúsculas es $($i+1)" Write-Output "El valor recuperado es $($ARRAY[$i])" Write-Output "La letra localizada es $($Matches.Values[0])" $detected = $true; } } if(-Not $detected) {Write-Output "El Array no contiene mayúsculas"} Here the script outputPS C:\Users\Alejandro\Downloads> C:\Users\Alejandro\Documents\test.ps1 Primer array a:1 a:2 a:3 A:4 a:5 La posición con mayúsculas es 4 El valor recuperado es A:4 La letra localizada es A Segundo array A:4 a:1 a:2 a:3 a:5 La posición con mayúsculas es 1 El valor recuperado es A:4 La letra localizada es A Tercer array a:4 a:1 a:2 a:3 a:5 El Array no contiene mayúsculas

So months are back from scratch, not from unit. November - 10, Decabr - 11, January - 0And in order to get the date you need, you might as well try:private String getDate() { Calendar calendar = Calendar.getInstance(); SimpleDateFormat dateFormat = new SimpleDateFormat("dd.MM.yyyy"); return dateFormat.format(calendar.getTime()); }

If by "standard" you mean the one that lets down the apps, then no. The developer's account is a separate thing. It can even be cut on the same mouse as the standard scab.
