Question

I’ve tried converting an EditText value to string repeatedly, and have tried everything I can find, but I am unable to correctly get the string value from an EditText value, then display it in a dialog. I made a basic activity to test it. Where am I going wrong? All this program is is one edittext box and one button.

package com.bensherman.example.etts;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import android.os.Bundle;
import android.text.Editable;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class EditTextToStringActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        EditText text = (EditText)findViewById(R.id.eTb);
        String convtext = text.getText().toString();


        final Builder vars = new AlertDialog.Builder(this);
        vars.setTitle("Saved Information");
        vars.setMessage("Entered Text: " + convtext);

        Button savedvars = (Button) findViewById(R.id.showButton);
        savedvars.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                vars.show();
            }
        });
    }
    }

the XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/eTb"
        android:hint = "Enter Text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <requestFocus />

    </EditText>

    <Button
        android:id="@+id/showButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show Text" />

</LinearLayout>

Answer 1

write this 2 line into the onClick() method

String convtext = text.getText().toString();
vars.setMessage("Entered Text: " + convtext);

or you can also write like this way

vars.setMessage("Entered Text: " + text.getText().toString());

and than

vars.show();
