I have layout containing 30 fields ( using editbox, spinners, buttons etc)
but it looks too weird with crowded elements. ( scroll view is also longer)
So i decided to keep 1 more button, so firstly 15 fields will display and 1 "More" button below,now i want to display rest of fields onClick "more" button on same layout ( below that 15 fields). How to do this, thanks in advance
I would suggest you to make a parent view with two main relative layouts. First relative layout for all the content you want to show at first time. Make this layout visibility View.VISIBLE. Second relative layout for all the content you want to show on click event. Make this layout visibility View.INVISIBLE.
On button click event make second relative layout visible by setting view.setVisibility(View.VISIBLE)
Don't forget the invisible the layout in the end. Otherwise it will be visible throughout the app session.
You can also set this property in your xml too. There is a android:visibility="visible" tag in every view.
This approach will help you in management because by setting a single view visibility you can manage your all view. Happy Coding!!

I have a strange behavior, I use a RecyclerView to display a list.
Each item of this list is composed of a LinearLayout containing 2 TextViews. (It's a classic configuration).
I have an OnClickListener on the LinearLayout and an OnLongClickListener on the second TextView.
The problem is that the OnLongClickListener prevents the "normal clicks" to reach the LinearLayout.
To summarize:
If I click on the first TextView, the Layout is clicked.
If I click on the second TextView, nothing happens.
You can't avoid this situation with your current xml file, you may need to make adjustment
Though if you want it with this design, you have to add OnClickListener to your second text that have OnLongClickListener and call inside it whatever you call on linearView.OnClickListener .
When you clicked on TextView just disable all click of linear layout because at a time one click listener will work.
linearlayout.setClickable(false);
linearlayout.setEnabled(false);
I have a Linear Layout
and I want to add to this Linear Layout a button (from 3 Buttons) Dynamic in Run Time Depending on an integer value that returns from a function
I know how to add a view to a Layout using AddView , and how to remove views form layout using removeView ...
but my question is how to check if the view Exists in the layout before call the method reomveView
I suggest you create your buttons beforehand and just set the visibility to View.GONE
when you trigger some event you can set other buttons visibility to true while the others are false..
this will work with no problems and you dont have to add them dynamically.. it will just "seem" dynamic :)
You can do that with this code:
button1.setVisibility(View.GONE);
button2.setVisibility(View.VISIBLE);
Given the buttons are "button1" and "button2"
View.GONE will "remove" the view from the screen, however it is still "there" it just doesn't appear for the user, and it doesn't take up any space
View.INVISIBLE will "remove" the view from the screen, how ever the space it took up is still used by it.
View.VISIBLE will show the view as it would usually.
I have an activity where the view is like a form, where user can enter the details and At the bottom there are two buttons "save" and "cancel". The form has many number of edit boxes.
So I have taken a relative layout and put all these edit boxes in it and then put the relative layout inside scroll view. I have taken another relative layout to add "Save" and "cancel" button.
Finally I have put the scroll view and relative layout(which has buttons) in another relative layout which is the main view of my activity.
My problem is , when I click any of the edit box, keyboard will come up and it hides the buttons(Save and Cancel).
I want to make the buttons to display above the keyboard(When the keyboard is on) like in the edit contact activity of "Contacts" Application .
I am using android:windowSoftInputMode="adjustPan|adjustResize" for my activity but of no use.
I have gone through so many stack overflow questions regarding this but I am not able to achieve this.
How can I do this with my code?
in Edit Contact activity save button is added to layout in bottom, and outside of scroll view.
What you can do, to make your save and cancel button visible all the time, wheather, soft keyboard is visible, or not. Make parent layout a relativelayout, in this layout add two views one scroll view, and other relativelayout having buttons. Let Relative Layout properties layout_width=fill_parent and layout_height=wrap_content, and align_parent_bottom=true, and scroll view's layout_width=fill_parent, layout_height=fill_parent, lavout_above=#+id/rlButtons, in ScrollView, add a RelativeLayout having all the editTexts.
I got the solution .
My parent layout is Relative Layout . In this layout I added a Scroll View and a relative layout. In the scroll view I added a relative layout which is having all edit texts. In relative layout I added save and cancel buttons. I set the scroll view weight = 1.
For my activity I set android:windowSoftInputMode="adjustResize".
In my app I want to have a button that if the user clicks it
than a new layout is opened within the current (acually the main) layout.
the new layout should not fill all of the screen and parts of the previous layout
should be grayed out.
Any ideas on how to do this ?
You can show a hidden layout within your button's onClick event by calling
view.setVisibility(View.VISIBLE)
You can also fade out view elements or whole views with
view.setAlpha(75);
view.setBackgroundColor(Color.GRAY);
Note that "view" in the first example is your layout element.. LinearLayout, RelativeLayout, etc. and in the 2nd example, "view" is the element(s) you're trying to gray out.
Follow the answer of SBerg413. And for more information. you can take the relativelayout for the part that you want to hide and display on the button click.
And as like SBerg413 answer. you can hide the respective layout and show the layout you want to display.
Hope it will help you.
Thanks.
you can use a ViewFlipper to achieve what you want, position the viewflipper where the child views should fit (part of the screen you say)..
Inflate the rest of the "child" layouts from other xml, add them to the flipper and switch between them when you want...
I want to display a recursive or nested text view at depth of 3 in Android.The text to be displayed is, dynamic coming from web service.
for example:
If I Click on Help(Level 1)
it'll show topics under Help
If I Click on Help_Topic_1(Level 2)
it'll show questions under Help_Topic_1
If I click on this question, say HT_Question_1(Level 3)
it'll show Answer of that question(Level 3)
how to accomplish with this? please guide me.
You should use ExpandableListView. Reference http://developer.android.com/reference/android/widget/ExpandableListView.html
You can call expandGroup and collapseGroup methods for expanding and collapsing on clicks.
the simplest way to do this is to have a nested layout structure. Your root view will contain the button to show level 1 and a child layout and initially be visible. The children's layout visibility will initially be set to "GONE". In the onclick listener for each button you change the visibility of the layout below it to view to "VISIBLE".
This of course is a very simple way of doing it. If you require to have open and close animations you'll need to use a more complex method.
