I am new to Android and Have to Port a Windows Mobile Application to an Android Application.

Issue: I need GridView in Android similar to .net GridView which is able to scroll in both Horizontal and Vertical directions at the same time.

As there are many rows and many columns in my data. So, all the columns are not shown as screen width is small on mobile. Multiple rows are shown as vertical scroll is enabled. What i want is that this GridView is somehow scrollable in both directions at the same time. So that user could view data in tabular form.

I am using GridView in Android with the help of TableLayout and SimpleAdapter. Following is my code:

Main Activity Layout:

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

<!-- This Table Layout is header followed by the gridview -->
<TableLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="5dp" >

    <TableRow android:layout_width="wrap_content" >

        <TextView
            android:id="@+id/schemeTitle"
            android:layout_width="80dp"
            android:layout_height="wrap_content"
            android:text="Scheme"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/nameTitle"
            android:layout_width="200dp"
            android:layout_height="wrap_content"
            android:text="Name"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/productTitle"
            android:layout_width="200dp"
            android:layout_height="wrap_content"
            android:text="Product"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/channelTitle"
            android:layout_width="80dp"
            android:layout_height="wrap_content"
            android:text="Channel"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/typeTitle"
            android:layout_width="100dp"
            android:layout_height="wrap_content"
            android:text="Type"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/customerSelectionTitle"
            android:layout_width="150dp"
            android:layout_height="wrap_content"
            android:text="Customer Selection"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/brandTitle"
            android:layout_width="80dp"
            android:layout_height="wrap_content"
            android:text="Brand"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/wsTitle"
            android:layout_width="50dp"
            android:layout_height="wrap_content"

            android:layout_height="wrap_content"
            android:text="End Date"
            android:textStyle="bold" />

  • You should have created a minimal example instead of copying a few files straight from your project – Max Mar 23 '21 at 19:15

I changed some code and finally able get tabular view.

Solution: I added HorizontalScrollView and now my LinearLayout is its child. Also I added android:stretchColumns="*" in TableLayout. Along with this i had to chnage android:layout_width and android:layout_height of different controls in following ways.

Updated code is below:

Main Activity Layout:

<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <!-- This Table Layout is header followed by the gridview -->
    <TableLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:stretchColumns="*" >

        <TableRow android:layout_width="wrap_content" >

            <TextView
                android:id="@+id/schemeTitle"
                android:layout_width="80dp"
                android:layout_height="wrap_content"
                android:text="Scheme"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/nameTitle"
                android:layout_width="200dp"
                android:layout_height="wrap_content"
                android:text="Name"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/productTitle"
                android:layout_width="200dp"
                android:layout_height="wrap_content"
                android:text="Product"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/channelTitle"
                android:layout_width="80dp"
                android:layout_height="wrap_content"
                android:text="Channel"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/typeTitle"
                android:layout_width="100dp"
                android:layout_height="wrap_content"
                android:text="Type"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/customerSelectionTitle"
                android:layout_width="150dp"
                android:layout_height="wrap_content"
                android:text="Customer Selection"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/brandTitle"
                android:layout_width="80dp"
                android:layout_height="wrap_content"
                android:text="Brand"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/wsTitle"
                android:layout_width="50dp"
                android:layout_height="wrap_content"
                android:text="W/S"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/startDateTitle"
                android:layout_width="80dp"
                android:layout_height="wrap_content"
                android:text="Start Date"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/endDateTitle"
                android:layout_width="80dp"
                android:layout_height="wrap_content"
                android:text="End Date"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/codeTitle"
                android:layout_width="80dp"
                android:layout_height="wrap_content"
                android:text="Code"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/tsidTitle"
                android:layout_width="50dp"
                android:layout_height="wrap_content"
                android:text="TSID"
                android:textStyle="bold" />
        </TableRow>
    </TableLayout>

    <GridView
        android:id="@+id/schemeGridView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"
        android:numColumns="1" >
    </GridView>
</LinearLayout>

</HorizontalScrollView>

Grid Layout:

Only following tag is chnaged:

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content" 
android:stretchColumns="*">

Source Code:

No change in Java code.

I got idea from: How can I make my layout scroll both horizontally and vertically? and How to put a very long table layout inside the horizontal Scroll view in the CORRECT way?

  • Hi I worked on that code a long time ago so can't remember. Moreover, that was a client specific code. Hence, that can't be shared. I don't have it. I believe the code provided in the question work with these configuration. – Muhammad Haris Altaf Jan 20 '17 at 16:43

The simplest solution is

  1. Use a horizontal scroll view to contain the GridView
  2. Then dynamically re-size the GridView width based on the number of columns that you set for the GridView

  3. Lastly, multiply number of columns with the width of each columns

    GridView gridView = (GridView) findViewById(R.id.grid_view);
int numberOfColumns = 3;
int sizeOfWidthPerColumn = 20;
gridView.setNumColumns(numberOfColumns);
ViewGroup.LayoutParams layoutParams = gridView.getLayoutParams();
layoutParams.width = convertDpToPixels(numberOfColumns * sizeOfWidthPerColumn, this);
gridView.setLayoutParams(layoutParams);

Now you are able to scroll the GridView horizontally and vertically.

    1. Use a horizontal scroll view to contain the GridView : For me I put GridView inside LinearLayout and LinearLayout in Horizental scroll. – Vikram Feb 02 '16 at 10:57
  • It's better to do like what you said as horizontal scroll view can only contain a single child view :) – Andrew Lam Feb 02 '16 at 11:00

I am not sure, if it's possible to scroll in both direction at the same time, but here's a library that helps you to scroll a GridView horizontally. https://github.com/jess-anders/two-way-gridview

Also you can have a look in here, How to make a 2-dimension image gallery with both horizontal and vertical scrolling?

  • Thanks Khobaib for replying. two-way-gridview doesn't provide both scrollings simultaneously. It does provide both but one at a time. And i didn't try other link. However, I found the solution and i have sent it. Thanks again :) – Muhammad Haris Altaf Apr 30 '13 at 15:16
