I want to create a custom list view.So i created a xml with list item and another xml for row item.For row items I have:
I have a Relative Layout.In which i added textview,Linear Layout.In the Linear Layout I added Horizontal Scrollview and in Horizontal Scrollview I added another Linear Layout with dynamic image views.
The problem is that after i added horizontal scrollview i am not able to do onclick.There is no effect of click.
Remove first LinearLayout in which you have added a HorizontalScrollView as it is useless for horizontalScrollView.After removing that add
android:descendantFocusability="blocksDescendants"
to the
RelativeLayout of Row.xml .
This should work

I am creating a layout which has two views in same line horizontally on top and below that all views are vertically arranged.I have read that its advisable to use linear layout wherever possible.However in this case if I have to use linear layout then I need to create another Linear Layout inside parent Linear Layout to hold top two views with orientation horizontal and my parent layout will have orientation vertical which will contain all views.
Instead if i use relativelayout as parent layout then all views can be arrange in single parent layout without the need to create any child layout.
Which is a better approach-nested linear layouts or single relative layout?
I have a Activity with a layout that is a Vertical LinearLayout with a RelativeLayout, ListView, and another RelativeLayout. My problem is if the ListView is longer than the screen, the bottom RelativeLayout will be unreachable. How can I ensure the last RelativeLayout is always at the end of the ListView? Can I make it part of the ListView somehow?
If you want the Bottom RelativeLayout to be fixed use the root element as RelativeLayout and use alignParentBottom = true to bottom RelativeLayout and position ListView below top relative layout and above bottom relativelayout.
if the bottom Relativelayout has to scroll as you scroll listview add it as a footer to the listview.Checkout this on how to add a footer to listview.
i suggest you to use recyclerview instead of ListVIew
I have a Linear Layout with many linear layouts inside. At runtime , I want to remove this layout(along with its child linear layouts) from the view subject to a condition. On removal, I want other layouts to be adjusted accordingly.
I tried this, but the layout remains.
if(getIntent().getStringExtra("ListingType").equals("Brief")){
extraLayout.setVisibility(View.GONE);
extraLayout.removeAllViews();
}
This Activity has 2 main Linear Layouts, 1 is DetailsLayout and 2 is ExtraLayout, both these layouts are relative to each other in a ScrollView. The main(root) layout of the Activity is Relative Layout
I am using a scrollview in which i have added 3 relative layout and a list so the stack is like
Scrollview
Relative Layout
Relative Layout
______ ListView
Relative Layout
Now when i am trying to add entries in listview it is now increasing its height. I have set wrap_content for the height field.
Use only listView and add the relativeLayouts as headers/footers.
Fix the height of listview because you are using scrollview
you can scroll and view that list while scrolling content inside listview.
Parent_LinearLayout
LinearLayout
TextView
LinearLayout
I have a parent Linear layout in the XML.
I created a Linear layout dynamically and whose child are TextView and A linear layout.
I added this layout to the Parent linear layout.
Now my question is how to get the Tag of Linear Layout(4th) and the Tag of its child (which i will add later dynamically).
for(int i=0;i<parent_Layout.getChildCount();i++){
View v=parent_Layout.getChildAt(i);
Toast.makeText(getApplicationContext(),""+parent_Layout.getChildCount() , Toast.LENGTH_LONG).show();
}
am trying to do something like this, but am not getting any idea how to achieve this
You can use something like setTag() on layouts...and later retrieve the layout using getTag().Hope that helps.
