Rady a tipy pro vyvoj ⇒ potize s vyvojem aplikace, uzivatelsky vstup

[max2]

Potreboval bych vytisknout vsechny binarni retezce pro zadanou promenlivou deku N a vedle nich na kazdem radku vytvorit
TextAreu kam uzivatel zada cisla napravo priklad: 0.11, 2.11, 4.60 ktera pote nactu a pouziji v aplikaci

000000000 0.11
000000001 2.12
000000010 4.60
000000011 5.34
...

Pokusil jsem se k tomu pouzit "linear layout" ale neumim v cyklu tisknout elementy
activity_main.xml.
Kdyby to bylo v souboru MainActivity.java tak snad ano, ale v .xml kde se elementy maji nachazet ne.
Takto se mi snad povedlo vytvorit jich jen konstantni pocet a to jeste pracne a nepresne v Design Editoru.
Jak to nejsnaze vyresit ?

[Crusty]

v xml si nadefinujes ten LinearLayout, ktery bude prazdny
a pak ve smycce volas neco jako
linearLayout.addView(new EditText(context));

+ LayoutParametry nastavit

Rada se mi zda funkcni, ale nemohl bys mi sem hodit nejaky MWE, jsem uplny zacatecnik a nevim jak to cele nastavit.
Diky moc. Max

tady je ukazka s vyuzitim toho LinearLayout. Ale pokud je tech hodnot (řádků) vice, tak urcite vyuzit RecyclerView (coz muzes vyuzit i tak, aspon se to naucis a je to pak hojne vyuzivane)

Tady nejaka testovaci Activity

Kód: Vybrat vše

import android.app.Activity;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;


public class AddToLinLayActivity extends Activity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_add_view_to_lin_lay);

        LinearLayout dynamicContent = findViewById(R.id.dynamic_content);

        LayoutInflater inflater = LayoutInflater.from(this);

        int numbers[] = {654, 213, 113, 213, 23, 45,84 };

        for (int number : numbers) {
            View newRow = inflater.inflate(R.layout.item_view_to_lin_lay, dynamicContent, false);
            TextView binaryString = newRow.findViewById(R.id.binary_string);
            binaryString.setText(Integer.toBinaryString(number));

            dynamicContent.addView(newRow);
        }
    }

}

ta vyuziva tento layout

<?xml version="1.0" encoding="utf-8"?>

Diky moc za cely kod.
Ktere XMLko mam ale pouzit, to 1. ci to druhe.
I tak mi to nejde zkompilovat, sviti tam cervene ta Rka,annotation a Nullable.

111.jpg (294.4 KiB) Zobrazeno 4972 x

[Crusty]

obe dve XML
R.layout.activity_add_view_to_lin_lay
je to prvni a
R.layout.item_view_to_lin_lay
je to druhe

annotation muzes smazat, i Nullable
R se vygeneruje az se to podari prelozit, tak to tak pak importujes svoje

[max2]

To mi prave neni jasne kam je ulozim.
Jsem zvykly mit jedno xmlko pojmenovane
activity_main.xml

A jak naimportuji R?

ANdroid Studio uzivam teprve tyden.

[Crusty]

ve slozce, kde ted mas ulozene activity_main.xml vytvoris novy *.xml soubor s tema nazvama co jsem psal
az je tam budes mit, zkus prekopilovat, hodi to chybu s tim R a pak kdyz kliknes v kodu na to R tak by ti to melo nabidnout import

[max2]

Zkusil jsem si napsat vlastni kod, ale nefunguje to, viz nize.
Chtel jsem vzdy na jednom radku
txt[1] tv[1]
...
txt[8] tv[8]

Muzes mi kod poopravit ?
Posilam .java i .xml.

Vyborne, uz jsem s tim pokrocil i sam, ale mam dalsi problem :

potrebuji precist do kodu data z tech dynamicky vytvorenych radku po stisknuti jednoho buttonu (button4).

Davam sem `.xml` i `MainActivity.java`, ktere bych rad upravil.

Nevim kam napsat `editText`. Kdyz ho napisi do funkce definovane mimo click2() tak nema pristup k datum funkce click2()

a kdyz ho napisi do ni, tak nebude reagovat na sve jmeno v activity_main.xml.

Kód: Vybrat vše

public void click(View view) {
        String col1;
        String col2;

        TableLayout tl = (TableLayout)findViewById(R.id.tableLayout1);

        TableRow row = new TableRow(this);
        TextView tv = new TextView(this);
        TextView c = new TextView(this);

        EditText etUserInfoNewValue = (EditText)findViewById(R.id.simpleEditText);

        tv.setText("This is text");

        tl.addView(row);

        row.addView(tv);

        for (int x = 0; x < 5; x++) {

            col1 = "(" + x + ")"+Integer.toBinaryString(x);
            col2 = "1";

            TableRow newRow = new TableRow(this);

            TextView column1 = new TextView(this);
            TextView column2 = new TextView(this);
            EditText editText1 = new EditText(this);

            TextView column3 = new TextView(this);


            column1.setText(col1);
            column1.setText(col1);
            column2.setText(col2);

            newRow.addView(column1);
            newRow.addView(editText1);

Nemohu nalezt chybu v nasledujicim zadani aplikace:
mame mnozinu hracu {1,...,n} a vyherni funkci z mnoziny vsech podmnozin do {0,1}.
Aplikace ma nacist vstupy ve tvaru binarnich retezcu delky n ,kazdy odpovida jedne koalici S,
a vypocitat kolik mnozin S ma vlastnost, ze v(S)=1 a v(S-{i})=0 pro kazdeho hrace i.

Kod jsem napsal ale je tam nekde zaludna chyba protoze napriklad
00=v({0,0})=0
01=v({0,1})=0
10=v({1,0})=0
11=v({1,1})=1

haze vysledek 0 namisto 1 (zastoupeno mnozinou {1,1}). Mnozin vsech takovych S pro vsechny hrace i dohromady maji velikost takovou, cemu v kodu rikam "swingove".
Melo by tedy byt swingove=1, ale dava mi to swingove=0. Nize prikladam MainActivity.java i aktivyty_Main.xml.
Doufam, ze nekdo poradi, fakt to nemohu najit.

Abych upresnil jak aplikace funguje, tak kliknutim na button4 po jedne zvysuji kolik ma byt vsech S,
kliknutim na button2 vygeneruji vstup a button5 vypocita dva vystupy, shap, ktery nas ted nezjima a banzhaf
ktery ma po retezci "K" vytisknout cislo swingove.

Kteroukoliv cats programu na pozadani vysvetlim.

hmmm tady moc nerozumim zadani, mozna nejak jednoduseji co to ma udelat? Matematicka zadani mi nikdy moc nesly

[max2]

Aha, a ja to napsal jak nejsrozumitelneji a nejjednoduseji to slo.
Zkopiruj sem vse pokud az rozumis. Nebo nejak oznac vse co je nejasne, kde se ztracis,co mam vysvetlit
Taky je moznost, ze si aplikaci zkompilujes a nahrajes do mobilu a napravo zadas pro nejake vstupy 0 a 1, a zadas kolik je koalici, nejlepe mocninu 2, muzes zkusit 2,4, ci 8.

[max2]

Mam maly problem, chtel bych uzivatelsky vstup v MultiLineTextArea mit velkym pismem.
Zadal jsem proto
android:capitalize="characters"

ale krome toho, ze je to v XMLku preskrtnute to ani navic nefunguje.
Nechci hledat jine reseni, rad bych zprovoznil toto, slo by to ?

app a tools nema v tomto roli, tak muze byt smazano. A na jake verzi emulatoru to zkousis?

[max2]

Nevim, zda je moje odpoved spravna, ale pise mi to
Android 12.0

Nezkousim emulator ale mam mobil s poslednim Androidem pripojeny kabelem primo k PC.


Vubec nechapu, proc nefunguje

android:capitalize="characters"

a proc je to preskrtnute ?

Dekuji

[max2]

Problem nalezen!
Ja mel klavesnici T9 namisto originalni a kdyz ji vypnu funguje vse spravne.
Diky za trpelivost.

[Crusty]

kdyz je to preskrtnute, tak to znamena, ze je to depercated, ze se to uz v novejsich verzich androida nepouziva, nebo nebude pouzivat

[max2]

Mam jeste otazecku: existuje v Atrributes u TextView policko, po jehoz zaskrtnuti text je bezici po strane mobilu
zleva doprava ? Nasel jsem Gravity, ale to je jen staticke umisteni, text se nepohybuje/nerotuje jak bych chtel.

[Crusty]

dela se to nejak takto, android:ellipsize
https://stackoverflow.com/questions/330 ... n-activity

[max2]

Dival jsem se na odkaz, ale pri zkopirovani do projektu mi sviti cervene toto
TextUtils:

txt.setEllipsize(TextUtils.TruncateAt.MARQUEE);

Co mam importovat ci jak to mam nastavit ?
Dekuji

[Crusty]

to co to nabidne, kdyz na to cervene das kurzor a pak kliknes Alt+Enter (na Windows) tak to nabidne moznost importu
Melo by to byt android.text.TextUtils

[max2]

Naimportoval jsem, ale text je stale staticky, prikladam kod z MainActivity.java

Vyhledej prosim MARQUEE a zkus najit proc je staticky.
Do dalsiho komentu prikladam XMLko takze mas vse.
