Menambahkan EditText secara dinamis di android studio

Bismillaahirrohmaanirrohiim…

Ada kalanya kita ingin membuat EditText di android secara dinamis.
Nah di bawah ini adalah kode java program android untuk membuat EditText menjadi dinamis sekaligus mengambil nilainya.

Konsepnya adalah kita membuat arraylist untuk menyimpan EditText,
kemudian kita masukkan beberapa EditText tersebut ke dalam layout.

Untuk mengambil nilai dari beberapa EditText tersebut, tinggal kita iterasi ArrayList tersebut dan dengan mudah kita ambil nilainya menggunakan editText.getText().toString()

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.TableLayout;
import android.widget.TableRow;

import java.util.ArrayList;
import java.util.List;

import static android.view.ViewGroup.LayoutParams.FILL_PARENT;
import static android.view.ViewGroup.LayoutParams.WRAP_CONTENT;
import static android.widget.LinearLayout.VERTICAL;

public class Sample extends Activity {
    private List<EditText> editTextList = new ArrayList<EditText>();

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

        LinearLayout linearLayout = new LinearLayout(this);
        ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(FILL_PARENT, WRAP_CONTENT);
        linearLayout.setLayoutParams(params);
        linearLayout.setOrientation(VERTICAL);

        int count = 10;
        linearLayout.addView(tableLayout(count));
        linearLayout.addView(submitButton());
        setContentView(linearLayout);
    }

    private Button submitButton() {
        Button button = new Button(this);
        button.setHeight(WRAP_CONTENT);
        button.setText("Submit");
        button.setOnClickListener(submitListener);
        return button;
    }

    // Access the value of the EditText

    private View.OnClickListener submitListener = new View.OnClickListener() {
        public void onClick(View view) {
            StringBuilder stringBuilder = new StringBuilder();
            for (EditText editText : editTextList) {
                stringBuilder.append(editText.getText().toString());
            }
        }
    };

    // Using a TableLayout as it provides you with a neat ordering structure

    private TableLayout tableLayout(int count) {
        TableLayout tableLayout = new TableLayout(this);
        tableLayout.setStretchAllColumns(true);
        int noOfRows = count / 5;
        for (int i = 0; i < noOfRows; i++) {
            int rowId = 5 * i;
            tableLayout.addView(createOneFullRow(rowId));
        }
        int individualCells = count % 5;
        tableLayout.addView(createLeftOverCells(individualCells, count));
        return tableLayout;
    }

    private TableRow createLeftOverCells(int individualCells, int count) {
        TableRow tableRow = new TableRow(this);
        tableRow.setPadding(0, 10, 0, 0);
        int rowId = count - individualCells;
        for (int i = 1; i <= individualCells; i++) {
            tableRow.addView(editText(String.valueOf(rowId + i)));
        }
        return tableRow;
    }

    private TableRow createOneFullRow(int rowId) {
        TableRow tableRow = new TableRow(this);
        tableRow.setPadding(0, 10, 0, 0);
        for (int i = 1; i <= 5; i++) {
            tableRow.addView(editText(String.valueOf(rowId + i)));
        }
        return tableRow;
    }

    private EditText editText(String hint) {
        EditText editText = new EditText(this);
        editText.setId(Integer.valueOf(hint));
        editText.setHint(hint);
        editTextList.add(editText);
        return editText;
    }
}
