EditText in array

[Milos Gojic]

Hello,
I wanted to put EditText in array.So that it can be printed several time.I don't want to make several EditText in XML i really wanted to avoid making robust xml.
I planned to make one EditText and then with loop displaying several time.
I did that with text but don't know how to do with EditText.
It should look like this:

Text    Edit text
Text    Edit text
Text    Edit text
Text    Edit text
Text    Edit text

I know for ArrayList and ArrayAdapter but i must make two more class and at the end it's the same like i made several EditTexts in XML... I want to shorten the code writing.I tried everything that i know i lost a day in something that should be an easy task....

my XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/root_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.example.korisnik.gradecardapp.MainActivity">


    <TextView
        android:id="@+id/lista_predmeta"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        tools:text="Prdmet" />

    <EditText
        android:id="@+id/lista_ocena"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:hint="ocena" />
    <TextView
        android:id="@+id/to_string"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        tools:text="Prdmet" />

</LinearLayout>

nad my JAVA:

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.EditText;
import android.widget.TextView;

import java.util.Arrays;

public class MainActivity extends AppCompatActivity {

    public MainActivity() {
    }


    private String predmeti[];
    private EditText listaOcena[];
    private String imeUcenika;
    private int ocene;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        listaUcenika();
        //listaOcena();
        TextView textView = findViewById(R.id.to_string);
        textView.setText(toString());
    }

    //This method is displaying TextView list
    public String[] listaUcenika() {
        predmeti = new String[5];
        predmeti[0] = "Istorija";
        predmeti[1] = "Matematika";
        predmeti[2] = "Geografija";
        predmeti[3] = "Srpski jezik";
        predmeti[4] = "Engleski jezik";
        for (int i = 0; i < predmeti.length; i++) {
            TextView textView = findViewById(R.id.lista_predmeta);
            textView.append(predmeti[i]);
            textView.append("\n");

        }
        return predmeti;

    }

    //This method is displaying EditText list
    // public EditText[] listaOcena() {
        /*EditText editText = findViewById(R.id.lista_ocena);
        listaOcena = new EditText[5];
        LinearLayout holder = (LinearLayout) findViewById(R.id.root_view);
int index = 0;
        for(int i=0; i<holder.getChildCount(); i++){
            View view = holder.getChildAt(i);
            if(view  instanceof EditText){
                listaOcena[index++] = (EditText) view;
            }
        }

        return listaOcena; */
    // }


    @Override
    public String toString() {


        return predmeti[0] + " Ocena: " +
                "\n" + predmeti[1]
                +
                "\n" + predmeti[2]
                +
                "\n" + predmeti[3]
                +
                "\n" + predmeti[4];
    }
}

Here are a couple of thoughts:

Have you looked into creating a custom view? Here are a couple of tutorials on how this can be done:

https://developer.android.com/guide/topics/ui/custom-components

http://www.vogella.com/tutorials/AndroidCustomViews/article.html

Maybe with a custom view you will not need to create a array of views.

You stated that you do not want to have an overly robust xml file.
Have you looked into dynamically adding and remove views as explained in these tutorials:
