I have one LinearLayout and it is center_horizontal.
It contains three buttons: left, middle and right. All were fixed in same row.
When I hide the right button programmatically it will hide the button, but not center the left and middle buttons.
I want the left and middle buttons to be centered in the layout when I am hiding the right button. Is this possible?
Making a view invisible, makes it only invisible which has its effect.
Try using gone instead of invisible and you are done!
Do the following settings:
1) Set visibitlity to gone
2) Set the width of ALL elements to 0dp and the weight of ALL to 1
Make sure that your three buttons are placed in LinearLayout with the orientation of horizontal, now use this code in Java file:
rightbutton.setVisibility(View.GONE);
Try this,
yourbutton.setVisibility(View.GONE);
What it does is, it stops the button from occupying any space on your screen which will in turn allow the other buttons to shift.
Just keeping it invisible will just hide the button from view, but it will still occupy the space and not allow the other buttons to adjust

I have a fragment where I want to hide and reposition a few textviews and imagebuttons programatically in case they are empty but I also want to put the other two that are below them, on top of the screen where those were in the first place.
.setTop doesnt seem to do move the view
`if (tr.getName().isEmpty()) {
tv1.setVisibility(View.INVISIBLE);
tv2.setVisibility(View.INVISIBLE);
imgb1.setVisibility(View.INVISIBLE);
tv3.setVisibility(View.INVISIBLE);
tv4.setVisibility(View.INVISIBLE);
imgb2.setVisibility(View.INVISIBLE);
}`
I make those invisible but how do I set the other components on top of the screen, basically on top of those that are invisible?
You should use:
view.setVisibility(View.GONE)
instead :
view.setVisibility(View.INVISIBLE)
I need to add a Button that is attached to the bottom of the screen so that it remain in that place when scrolling (other widgets move, but this don't). How to do it?
Put everything that you want to scroll in scrollview.
You want that button at the bottom of the layout. Set android:layout_alignParentBottom="true" in the xml of the button.
In my application I want to have sliding menu on the left side just like facebook.
In my previous question I had raised concern regarding the same and thanks to this answer that I could found a way to slide my layout to right using this library. But, I found that, the library does not actually slides the layout, instead it just takes the screenshot and slides the image towards right as the components on the layout are not clickable. And I need those components to be clickable. So, I tried a new way of achieving this by putting the slideout menu on the left by keeping its default visibility to View.GONE and make it visible on click on left top corner "Show/hide Menu" button as shown in figure below.
Layout before:
Now when I click "Show/Hide Menu" button, the layout is something like-
Layout after:
As you can see, the layout on the right shrinks and so the button "Some other view" changes its width even if I've set the android:minWidth attribute to those two buttons on the right as well as its parent RelativeLayout.
So my question is, is there any way to shift the layout towards right without the inner components changing their width/layout? So in whatever area is available for my view, it will be filled by whatever portion of the content that can be filled in in that area.
This problem can be solved like this:
create framelayout with inside: first left menu with 3 buttons and second layout that contains other two buttons (show/hide and other view). This way, the second layout is in front of menu (since it is fill_parent).
in onClick of show/hide button perform translate animation: assuming that your menu is 200px wide, move the second layout by 200 to the right.
in onAnimationEnd, set margins to the second layout like this: secondLayoutLayoutParams.setMargins(200, 0, -200, 0);
Closing menu is similar: move the second layout to the left by 200 and set all margins to 0.
By setting margins you will avoid button shrinking.
Hope it helps
#Rajkiran - I have a root layout, that contains my left & right layouts.
My right layout has layout_height set to 'match_parent' & layout_widht is also set to 'match_parent'
Now when my left sliding panel appears on button click, I reset the width & height of my right layout programmatically to match the width & height of the root layout.
This perfectly shifts the right layout towards right without the inner components wrapping up.
To change height & width programatically I used this -
rootLayoutParams = new LayoutParams(rootLayout.getWidth(), rootLayout.getHeight());
rightLayout.setLayoutParams(rootLayoutParams);
Hope it helps you as well.
Background:
I have an Activity that comprises four buttons that each take up a quarter of the screen.
It contains a horizontal LinearLayout that is divided in half by two vertical LinearLayouts as shown in the image below:

Desired Effect:
When I touch a button, I would like it to animate and fill up the entire screen.
Issue:
I have accomplished the animation aspect by changing X and Y scales from 1 to 2 onClick.
The problem is, however, that the animated button will not show when it leaves its parent LinearLayout.
Thoughts
I have tried making the non-animated buttons invisible, but the animated button will only show in its parent LinearLayout.
I know this problem would be solved if I had used a single LinearLayout, but I was unable to use the "layout:weight" feature to make each button take up half of both width and length.
So... How should I approach this issue?
I would appreciate any help :)
Try using a single RelativeLayout. Check this post for a nice example. You may have to setVisibility(View.INVISIBLE) for the other buttons.
Alternative:
Construct a RelativeLayout as above but put that as the only child
of a FrameLayout.
When animating a button, remove it from the RelativeLayout and add it to the FrameLayout specifying the gravity in the LayoutParams appropriately. This way the rest of the buttons will also be seen in the background during the animation.
I have a top section for the app which is mainly logo and stuff, and roughly the bottom half is supposed to be buttons.. In the outer container, i have a layout for the logo, and imageView to create a seperator line between the top and bottom and the bottom layout..
The issue is bottom layout has 2 linearlayouts (one of which is hidden initially) first one is just a spinner and the second one is 2 buttons..
I have achieved the "roughly 1/3 of space) by using layout_weights in the top and bottom linear layout (2 and 1 respectively) but when I hide the spinner and show the 2 buttons in the bottom layout in the code, the seperator line is pushed up.. I want it to stay in the same place (like be where it would be after the 2 buttons show up from the get-go so that it doesn't have to move)
I could probably just add some margin to the original one to match it but i feel like that will cause issues in the future on different devices.
How can I accomplish this feat?
I think you might be neglecting to set android:layout_height="0dp" on the LinearLayouts that you set android:layout_weight="1" on. If you do this it should fill the space like you want, and you can do layoutView.setVisibility(View.GONE) and layoutView.setVisibility(View.VISIBLE) to toggle the views.
