Android Horizontalscrollview Content Stretch

I have a HorizontalScrollView with some buttons, I am trying to stretch these buttons to fill the whole width of the HorizontalScrollView so that they can appear organized and equa

Solution 1:

Instead of messing with LinearLayout you should follow the correct solution that is setting the HorizontalScrollView (or Vertical) to FillViewPort.

XML:

android:fillViewport="true"

Programmatically:

hsv.setFillViewport(true);

Solution 2:

For equal distributions, set the weightSum value of the parent, and assign layout_weight to its children.

For 4 equal sized buttons, add android:weightSum="1" to the LinearLayout. For each of the buttons set android:layout_width="0dp", then add android:layout_weight="0.25".

This is what occurs in the code but depending on the View, the "Distribute Weights Evenly" button in the Eclipse GUI can also help.

However, HorizontalScrollView can only host one direct child, I wonder about the structure of this layout...

Solution 3:

try making the container a horizontal scroll view. After that add in a table layout, and in each row of the table add in a horizontal linear layer. what will now happen instead, is that the scroll view will be stretched to fit the button size you set, and should scroll w/o you having to program a thing, and you should have effectively created a grid. try something similar to this:

<?xml version="1.0" encoding="utf-8"?><HorizontalScrollViewxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/sc1"android:layout_width="match_parent"android:layout_height="match_parent"android:scrollbars="horizontal" ><TableLayoutandroid:layout_width="match_parent"android:layout_height="match_parent" ><TableRowandroid:id="@+id/tableRow1"android:layout_width="wrap_content"android:layout_height="wrap_content" ><LinearLayoutandroid:layout_width="wrap_content"android:layout_height="wrap_content" ><Buttonandroid:id="@+id/button1"android:layout_width="180dp"android:layout_height="wrap_content"android:text="Button" /><Buttonandroid:id="@+id/button2"android:layout_width="180dp"android:layout_height="wrap_content"android:text="Button" /><Buttonandroid:id="@+id/button3"android:layout_width="230dp"android:layout_height="wrap_content"android:text="Button" /><Buttonandroid:id="@+id/button4"android:layout_width="233dp"android:layout_height="wrap_content"android:text="Button" /></LinearLayout></TableRow><TableRowandroid:id="@+id/tableRow2"android:layout_width="wrap_content"android:layout_height="wrap_content" ></TableRow><TableRowandroid:id="@+id/tableRow3"android:layout_width="wrap_content"android:layout_height="wrap_content" ></TableRow><TableRowandroid:id="@+id/tableRow4"android:layout_width="wrap_content"android:layout_height="wrap_content" ></TableRow></TableLayout>

Also perhaps you could wrap the horizontal scroll view in a vertical scroll view then you can scroll up/down, left/right and do as you need.
