Android Question Focus on an EditText

[nibbo]

Hi, I am working with a multi column scrollview. Each line in the scrollview has an edittext.
When the scrollview is touched (or one of the labels in the row clicked) I want to set the focus to the edittext control on that row.
I am able, using the label click event, to construct the tag name for the edittext but cannot find how to set the focus of a control using it's tag.
Many thanks

What are you storing in your Tag? You need to get the edittext object, then you can do EditText.RequestFocus.

Thanks Steve
The tag for the edit control is made up of a fixed string (i.e. "etName") and a number which happens to be the row within the scrollview.
All other controls (labels) in the row have a tag name of just the row number so I can derive the edittext control's tag name in the but I am unsure how to get a control using its tag name.

You can't.
You can get the EditText with ScrollView1.Panel.GetView(Index)
The index depends on how you filled the ScrollView.
The view index begins with 0 and is incremented by one each time you add a new view.
Example: If have on each line a Label, an EditText and a CheckBox.
The Tag property of each view is the row index.
View Line Index
Label0____ 0 0
EditText0 _ 0 1
CheckBox0 0 2
Label1____ 1 3
EditText1_ 1 4
CheckBox1 1 5
Label2____ 2 6
EditText2_ 2 7
CheckBox2 2 8

The the index of EditText2 in row 2: rowIndex * 3 + 1 = 2 * 3 + 1 = 7

Dim edt As EditText
edt = ScrollView1.Panel.GetView(row * 3 + 1)
edt.RequestFocus

In this example 3 is the number of views per row.

You can't. If you are storing various data in a tag I suggest you use a Type, you can then store the Edittext object and other data and get it directly.

Thanks for all of the replies, they helped a lot; the final solution if anyone else needs it...
Each row in the scrollview is a panel with three labels and an edit text, all of which have their tag set to the row number.
For each label click event I call a common sub routine that uses the tag value to determine the row thus...

Sub ProcessLabelClick(lbl As Label)
    Dim pnl As Panel
    pnl = scrollViewName.Panel.GetView(lbl.Tag)
    Dim et As EditText
    et = pnl.GetView(3)
    et.RequestFocus
End Sub

Thanks again.

The next bit is how to make the keyboard appear when the edittext gets focus...

Just to update the above. Using IME and show keyboard will set the focus to the required edit text and show the keyboard so replace the et.RequestFocus with:

Dim inputMethod As IME
inputMethod.Initialize("")
inputMethod.ShowKeyboard(et)
