Horizontal Scroll View, Scrolling Issue Android

Question

I am new to android programming. I am implementing a simple calculator and I am facing issues with horizontal scroll View. I am using an edit text within Horizontal scroll view. It works completely fine for the first time but as soon as I clear the screen it retains it scrolling limit, meaning that even though there are few digits on the screen I am able to scroll more than it. What I want to achieve is to limit its scrolling. Below are the screen shots and XML code.

First Time

[Second Time][2]

It is still scroll-able even though there are few digits

 <HorizontalScrollView
        android:id="@+id/hsvMain"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end"
        android:scrollbars="none"
     >

        <EditText

            android:id="@+id/mainEditText"
            android:paddingTop="10dp"
            android:paddingRight="2dp"
            android:background="#ffff"
            android:ellipsize="end"
            android:focusable="false"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:textSize="55sp"

            android:textStyle="bold"

             />

    </HorizontalScrollView>

Try changing round the layout height/width attributes, make HorizontalScrollView layout_width="fill_parent" and EditText layout_width="wrap_content" and layout_height="wrap_content"

<HorizontalScrollView
        android:id="@+id/hsvMain"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="end"
        android:scrollbars="none">

        <EditText
            android:id="@+id/mainEditText"
            android:paddingTop="10dp"
            android:paddingRight="2dp"
            android:background="#ffff"
            android:ellipsize="end"
            android:focusable="false"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="55sp"
            android:textStyle="bold"/>

</HorizontalScrollView>

Edit :

The reason why is wasn't working before because you were telling the scrollview to wrap the content regardless the size of the EditText , so it would only scroll around the EditText . But if you tell the ScrollView to match_parent , it'll always be the width of the screen and then the EditText can be scroll within the parent ( ScrollView ) regardless of the size.

Note : use match_parent instead of fill_parent , fill_parent is now deprecated. (Although still works)
