I have a custom list row which has two TextView and one EditText .
I want to clear the text typed in EditText of all the list rows on a Button click which is a reset button.
The Button is in an Activity
Can anyone suggest me a way I can achieve this.
Well your question is not clear at first, if you mean a system like listview or scroller when you say custom list row, then while on click of button do the following
Get all the child from the view
loop through each child, finding EditText inside each child view
Simply setText to empty.
I hope got your question right, else please put some code here.
You can use this to clear the editText
YourEditText.setText("");

I'm trying to create a Ordering layout. I completely tried to use BaseAdapter and yet don't get the idea of using LayoutInflater
The picture above shows Spinner, EditText, EditText, and Button which represent Spinner for Item, edittext for Price and Quantity, and the button for (Insert,Edit,Delete).
The problem is.. if I click the Button, it will display the same views to the next row and Button will be set (Edit) and once I click it.. a way that I can set IDs in the views.
Any help will be appreciated.

inflater is just something packaging the layout defined in your xml to coding as an object.
Need to implement edit in runtime. Which one is the best way to achieve it.
Edittext in Listview or dynamic table layout(inflating row xml) with edittext
Update:
My listview contains 7-8 view(Text view) in a list item. On click edit button using view switcher changed textviews to edit text. To get the entered value in edittext listening onfocuschanged. It brings very slow performance. Any better way to achieve it?
Update:
If my listview have 100 list items. Each item having 7-8 edittext. Need to listen all the edittext focuschange. My app hangs. What should i do?
EditText within ListView can cause you great grief down the lane given that views are recycled in listview.
Say you have tapped on the second row in a listview where all item rows contain a edittext and you have set adjustResize in your AndroidManifest.xml; after the soft keyboard pops up, the focus goes into the first view that can accept the focus which in this case will be the first edittext (row) of your listview. Yes, you can tap again on the desired edittext to regain focus. But it is an annoyance nevertheless. If you set adjustPan, then I have seen the the problem does not exist as such; if I recollect correctly, you cannot scroll down all the way to the end of your list. Again, another annoyance.
I'd suggest, you go with a ScrollView if the number of items in the list are less. I have been trying to solve this for the last couple of days - I ended up doing this - I replaced the edittext's with textview's in the listview; tapping on the textview would bring up a dialog fragment that contains the edittext.
Have you looked into the concept of a ViewHolder to keep a reference to the items of the listview? That should solve your multiple focus listener problems.
I don't know if this is the right method but I would like to know if is it possible to show a Listview when the user clicks on an EditText/TextView and show afterwards the selected item text in this EditText. I know how to declare the EditText in the layout but is there any example of when clicking on the listener show the ListView? Do I need to add this Listview in the XML layout or do I have to add it programatically?
Thank you
if your app wants to have a sort of text viewand when you click on it you need to show up a list view then you can use expandable list view check this tutorial

Sorry, a I was looking just for a Spinner, I thought that it was another type of ListView
I have a GridView to which a custom adapter is set. getView() method of the custom adapter returns a LinearLayout with two TextView and an EditText arranged horizontally. I have made a custom numeric keyboard for entering text in the EditText. Keyboard contains NEXT and PREV buttons as well which are creating problems. I want NEXT button to automatically focus the next EditText in the next row and similarly PREV button. NEXT button onKeyPress seems like:
View v=getWindow().getCurrentFocus().focusSearch(View.FOCUS_FORWARD);
if(v!=null)
v.requestFocus();
The code seems right. The problem is, suppose currently only three rows are visible of gridView,if the focus is on the third EditText and NEXT is pressed,it then focuses on nothing. I dont know how to solve this issue. If anyone knows how to solve it.
Thanx in advance.
Can you maintain a collection of ids of all the editText's in the same order, while adding them for rendering.
In that case, for clickHandler or NEXT/PREV button, u can check following:
clickHandler of PREV: if present selection is first in list, then you might want to set focus on last element in list.
clickHandler of NEXT: if present selection is last in list, then you might want to set focus on first element in list.
Alternatively, if you do not want a list roll back functionality, you can just check the position of element in list, and handle the brink elements any way u want them to be.
Hope I understood your problem correctly.

This is my first project in android and I want to display something like this in list view
Any advice is appreciated
You can go through CustomListView example.it can be done easily.
Please go through the Link below
how to customize listview row android
For achieving this layout you should use custom listview for that like it.
A row with one text view and four button mean five object in each row but show only two object one is textview and another is one button out or four button.
If you want to display fourth button then invisible first there button and fourth button in visible state.
If you want to display second button then first, third and fourth button invisible state only second button in visible state.
Fallow this logic in each row.
I hope you got you answer after using this logic.
