SIMPLE EDITTEXT

SOURCE CODE [main.xml] is

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

<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />

<EditText android:id="@+id/edittext"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />

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

</LinearLayout>

SOURCE CODE [EditTextExample.java] is

package com.EditTextExample;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class EditTextExample extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
                               
final EditText et;
final Button b;
       
et = (EditText) findViewById(R.id.edittext);
b = (Button) findViewById(R.id.button);
       
                                b.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
                                                                String text=et.getText().toString();
                                                               
                                                Toast msg = Toast.makeText(getBaseContext(),
                                                                                text, Toast.LENGTH_LONG);
msg.show();
                                                }
                                });
}
}

The OUTPUT will be

    Hi I am realy new to Android. I am trying basic now and just copied you code and xml part and run it on the emlulator but I get the following error:

    "11-06 13:37:04.868: E/AndroidRuntime(769): Caused by: java.lang.NullPointerException
    11-06 13:42:23.849: E/AndroidRuntime(817): at my.test.Test.onCreate(Test.java:25)
    "


    the error points to the following line in the code:


    b.setOnClickListener(new OnClickListener()


    Below is the whole code:

    package my.test;


    import android.app.Activity;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.Toast;

    public class Test extends Activity
    {
    public void onCreate(Bundle savedInstanceState)
    {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final EditText et;
    final Button b;

    et = (EditText) findViewById(R.id.edittext);
    b = (Button) findViewById(R.id.button);

    b.setOnClickListener(new OnClickListener()
    {
    public void onClick(View v)
    {
    String text=et.getText().toString();

    Toast msg = Toast.makeText(getBaseContext(),
    text, Toast.LENGTH_LONG);
    msg.show();
    }
    });


    Hope someone can help me.

    Check your android manifest.xml file. The starting activity should be "Test". just check it out.

  3. Is this possible for web pages?

  4. your code error line is :b.setOnClickListener(new OnClickListener()
    apart from that try this : b.setOnClickListener(new View.OnClickListener()

  5. Jack says:

    hi sivakrishna.

    b.setOnClickListener(new OnClickListener() will also work because i have imported only one class having the name "OnClickListener".

    import android.view.View.OnClickListener;

    But, You said is also right.
