I have 4 editText
I want the user to set one digit in each of them sequentially.
how would you suggest enumerating the controls?
Is there any attribute I can override which will save the next editText control's id?

How can I do this When User Click On the Next Button Activity Should not change only data should change for example if there is TextView then its data should change and so on.
I want output like This Gif
If you have any doubt please feel free to ask in the comments
I think this is able to do with the help of animation.
There are a couple of ways you can do this. You will need to have a list of data which will hold the title and the images. Then you can do one of the following
On your button click, change the text of your TextView and set the image resource of your ImageView by fetching the next item of the list manually each time.
You can use a ViewPager and update the current page when you click on the button
You can use a ViewFlipper and manually add Views based on your data and change views on button click
To achieve this view take on int counter with initial value 0 and use CountDownTimer method.
Create list which contains image and text values in model. on CountDownTimer method every tick you can increase the counter and set image and text again from the list index.
I'm trying to find the best approach to handle a user clicking a button, setting the text of that button to (in my attempt) a textview and then automatically move onto the the next textview to update on the next button press.
At the moment I can do this by manually specifying each element by ID to update but there must be a better way, or a different approach.
An example: imagine a table with 2 rows of each 4 columns (each contains a textview) and below that 6 buttons. When any button is pressed the first time the textview of the first column is set to the button text, the next press of any button sets the the textview of the second column is set to the button text, and so on. When a row is complete it will start back at column one of the next row.
at the moment I'm using a hard coded function triggered by the onclick event, I realized that I could implement some counter and user row[i]_col[j] (or such) but is there a better way to approach this (eg. some way similar to changing focus on edittext)?
public void setValue(View view) {
TextView textView = (TextView) findViewById(R.id.textView_row1_col1);
textView.setText(((Button) view).getText());
}
If i understood your problem correctly ,
I would suggest using an array of Textviews instead of using findviewbyid so much (very pricey memory wise )
TextView [][] txtArr = new TextView[XSize][Ysize];
Initial that in the start once and use it in the on click later.
I am using custom adapter for listview. In row layout contains, two EditText view & one image view. I want read value of EditText view on button action(which will be clicked at ending). When I manually write entries in edittext box, I am unable to call 'notifyDataSetChanged'. So only old values are set to adapter. Now at end, how to read current data directly from edittext view.
Event editText.getText() also not working. It shows previous data, not modified data.
Thank you in advance.
Finally it is fixed.
My main problem was if EditText view is edited, I need to catch that event. If i use TextWatcher, it signals only when text will be changed.(not when editing is done completely). To catch editing is done, I used dialog. So when user try to edit value from EditTextView, I show dialog with EditText. When 'Ok' will be pressed, it signal that editing is done.
And then update my value.
all,
We know on Andorid, for a EditText, by default, whenever the EditText is clicked, the soft keyboard pops up to let you enter text. When you click DONE, it closes out and put the text directly to the EditText.
Now, what I am trying to do is, instead of an EditText, I have an ImageView which is to let user enter some comment.(So the ImageView actually is an comment icon). I wish whenever the icon is clicked, it pops up the text editor with user previous entered text, again once the DONE is hit, it closes out and I can save whatever text there back to a string member of the Activity. Is that possible?
So far, all I've seen about InputMethodManager is on EditText control, If it is too complicated, I probably just put an EditText into a sperate Activity.
Thanks.
There are many solutions:
One is to use custom dialog: http://developer.android.com/guide/topics/ui/dialogs.html#CustomDialog
Second one is to use a transparent activity on top of that one.
Then you could use FrameLayout and insert another view in an exact position...
I think you should try the frist or second one. Every ImageView can be easily converted into a button by adding onClick event to it.
For my Android application, I want to have a view which allows a user to click a plus button to add EditText fields, and next to the EditText fields, I want to have minus buttons that will remove them from the view. In essence, something that is very similar to adding multiple phone numbers/email addresses in the edit Contact interface on Android.
I imagine I will need to do this by inflating my main view with a separate one that contains the EditText and button I want to add each time. However, I have no idea how I will manage identifying each EditText and button with a unique ID, and thus, I have no idea how I would manage to grab the values of each EditText for saving to my database. Can someone advise me on what I need to do? Thank you.
If you have inflated a sub-layout, then you should now have a View object.
You can then call findViewById(R.id.edit_text_1) on that View — assuming that you supplied IDs in the sub-layout XML.
So long as you keep track of each of the parent Views, you can always use findViewById() on them. Or after inflation, if you really want you can set a new, globally-unique ID on each EditText using setId().
You can assign a view widget dynamically, and generate your own ID as it is assigned.
Button b = new Button(this);
b.setId(myId);
Then you can refer back to that widget.
findViewById(myId);
