        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="140dp"
        android:layout_marginLeft="38dp"
        android:text="@string/btn" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"

        android:layout_alignLeft="@+id/editText1"
        android:text="@string/title"
        android:textSize="@dimen/tsize" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/editText2"
        android:layout_alignLeft="@+id/button1"
        android:layout_marginBottom="24dp"
        android:ems="10"
        android:inputType="number" >

        <requestFocus /></EditText>

    <EditText
        android:id="@+id/editText2"
        android:layout_width="wrap_content"
        android:layout_height="@dimen/msgheight"
        android:layout_above="@+id/button1"
        android:layout_alignLeft="@+id/editText1"
