I cant find documentation on how to programmatically set. We have scroll view with matchparent height but still two buttons which want to keep at the bottom are right below the small text. The tablerow objects has 2 items a textview and a checkbox. To create a linear layout in which each child uses the same amount of space on the screen set the androidlayoutheight of each view to 0dp for a vertical layout or the androidlayoutwidth of each view to 0dp for a horizontal layout. Even with invalidate or requestlayout. It does mean that the height of scroll view is considered as wrapcontent even if the value of androidlayoutheight is matchparent.

Step 1 create a new project in android studio go to file new project and fill all required details to create a new project. To create a linear layout in which each child uses the same amount of space on the screen set the androidlayoutheight of each view to 0dp for a vertical layout or the androidlayoutwidth of each view to 0dp for a horizontal layout. After that the wrapcontent in layoutparams is lost. In this case the highest weight is button3 so it will fill up the remaining space in the layout. The textview items need to have their layout weight set to 1 to push the checkbox items to the far right. Open reslayoutmainxml file add 3 buttons within linearlayout with horizontal orientation.

Here is the problem exists. Layoutweight assigns weight to the children of linearlayoutfor example if there are three child items within the linearlayout then the space assigned will be in proportion to the weight which means the child with larger weight will be allow to expand morethus weight decides how much space an item is allowed to occupy on the screen. Step 2 add the following code to reslayoutactivitymainxml. Android does not refresh layout of views with wrapcontent once it has been displayed. This example demonstrates how do i set the layout weight of a textview programmatically in android. Then set the androidlayoutweight of each view to 1.

Then set the androidlayoutweight of each view to 1. So if you add a child view or modify the content dynamically youre screwed. Im trying to dynamically create tablerow objects and add them to a tablelayout. Getlayoutparamsheight x plus requestlayout are a good solution if you know the x and if you need to do it only once.
