Question

i have created two buttons and a textbox. the textbox shows the text that i referenced but the buttons don’t show the text as referenced. Instead they show “button”. Also when i run the application on my emulator then the application stops. Please Help!

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/txtDisplay"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="@string/Disp"
        tools:context=".myMain"
        android:textSize= "45dp"
         />

    <button
        android:id="@+id/bAdd"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="@string/hello_world"
        android:textSize="45dp" />

    <button
        android:layout_gravity="center"
        android:layout_width = "wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world"
        android:id="@+id/bSub"
        android:textSize = "45dp"/>


</LinearLayout>

Here is the Strings.xml

<resources> 
<string name="app_name">Basictut</string> 
<string name="hello_world">Hello world!</string>
 <string name="menu_settings">Settings</string>
 <string name="title_activity_my_main">myMain</string>
 <string name="Disp">Your Total Is 0</string>
 <string name="add">Add one</string>
 <string name="sub">Subtract one</string>
 </resources>

Java Code is:

package com.example.basictut;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v4.app.NavUtils;

public class myMain extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
         getMenuInflater().inflate(R.menu.activity_my_main, menu);
         return true;
    }


}

The xml is case sensitive, I think you should write Button instead of button.
