Android : Unable to set TableLayout properly as wa

问题:

I am showing data from DB in an Activity. I want a Table and buttons on bottom. For data thought TableLayout would be best option for it. I added TableLayout to HorizontalView & to ScrollView making it scroll vertically & Horizontally. Am adding all rows dynamically - including header. This part is working fine.

I want is when the contents is less than the screen width, it should yet occupy the whole screen width. For eg. If a table fits well in Portrait mode then ofcourse for Landscape mode their will be blank space left on the right. I don't want that space to eb empty, instead to occupy by all columns. If the row width is greater than the screen width then no issues at all - as horiontal scrollbar appears.

I tried few variations, but nothing helped out. Any idea what settings to make to utlize all space (if at all avbl) & show it.

And yes, 1 more issue of horizontal scrollbar, it appears just on the last row. I want it to appear below last row - so the border of last row is visible. My XML :

<?xml version="1.0" encoding="utf-8"?>

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

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:scrollbars="horizontal|vertical">

<HorizontalScrollView android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_marginTop="10dp" android:layout_marginBottom="10dp" > 

<TableLayout android:id="@+id/browseTable" android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:layout_marginBottom="20dp"
    android:background="#FF0000" android:stretchColumns="1,2,3">

</TableLayout>

</HorizontalScrollView>
</ScrollView>

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content" 
android:orientation="horizontal"  android:gravity="center" 
android:layout_marginTop="15dp">
    <Button android:id="@+id/browseAddBtn" android:text="Add" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:layout_marginRight="10dp" />
    <Button android:id="@+id/browseViewBtn" android:text="Edit" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:layout_marginRight="10dp"  />
    <Button android:id="@+id/browseReturnBtn" android:text="Return" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" />        
  </LinearLayout>

</LinearLayout>

I found one thing while solving your problem, about TableLayout when used inside a HorizontalScrollView. The android:stretchColumns is not working when we use Table Layout inside Horizontal Scroll View. So that you are getting blank space when screen is rotated or columns have less width data.

I hope you understand this. I am trying to solve this problem by replacing Horizontal Scroll View with some other. I will post answer if i get solution. Bye.

EDIT

Hi Tvd finally I got the solution for your problem. make below changes to your XML layout file.

In <HorizontalScrollView>

use

        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:fillViewport="true"

Use stretchColumns = "*" in TableLayout if you want all columns to be stretched.

Bye. :-)
