Android Onclick priority: ListView or ImageView in ListView? - java

Theorical question
I have a listview populated with items, which layout is defined by one TextView and one ImageView.
I set an onclick listener on my listview for any item.
I set an onclick listener on my ImageView within my layout
Which one gets the priority when I click on my image and why?
How do I write code to manage this priorization?
Thanks!


You can add the attributes
android:focusableInTouchMode="true"
android:focusable="true"
for a layout that contains TextView and one ImageView.

I have a layout with two fragments. Both fragments have a Recyclerview. I want, When I scroll any of a recyclerView Then another recyclerView also scrolled automatically. How can I do this?

If you don't see each fragment at the same time, you could get the position of the viewable RecyclerView when you change views, then set the other RecyclerView to the same position.

I need to create a layout with a list of checkboxes on the left and text on the right. However, I need them to be laid out in a very specific way. I've searched for such a layout in many places, but no success (the closest I got to what I want was this.
This is the layout I need for my list
Can I achieve this with a ListView?

You can do it using ListView easily.
You should create your own Adapter and override your getView there
and return a RelativeLayout with your components inside e.g. a Button and a TextView
and set this adapter into your ListView.

Pressed Status propagation in Android

I have a layout with the following structure:
LinearLayout_1
ImageView
TextView
Linearlayout_2
ImageView
TextView
Some Views within LinearLayout_1 have padding and margins. I want to set a OnClickListener over LinearLayout_1 (for detecting clicks in the whole layout). But when its pressed I need all the items inside in pressed status. How can I do that? Thanks

Found a solution. The key is to use
android:duplicateParentState="true"
in the childs of the View where the clicks are listened

Can i extend the size of a listview dynamically in java code

I am using a listview in a layout with a size- not in full size of layout.
Below the layout there are components like button.
I need the layout to get extended when more number of listitems adds dynamically.
I have kept the listview and buttons in scrollview.
Is there any attribute or option to make listview of variable length

You should not have a listview inside a scrollview. Instead of having a listview you should add your items to a linearlayout, which will grow to accomodate the items and not enable the scrollbar within itself. This will solve your UI issue. You can set the onclickListeners in a for looop.
Update
<ScrollView.....>
<LinearLayout .....>
<LinearLayout ..../> // this has your list items
<Button .... /> // you can have a layout here if you have multiple buttons.
</LinearLayout>
</ScrollView>

Set the ListView's layout_height value to wrap_content, and it will stretch to accomodate all the items' views in its adapter.

In android how to place components in a listview with items?

I am using a listview with listitems and there is a need for me to add button near each listitem. How can i make it possible.

you need to have your own custom adapter and in that you have to set the layout in the getView() method. Now in the layout file that is the xml file keep the button.
