I am trying to add an animated spinner inside a EditText view to the right. And programmatically show/hide it.
I have created the animated spinner by introducing a linear interpolation rotation. code...

Adding an image on EditText works fine. However, copying an image is another problem. When I insert an image on EditText by using ImageSpan it shows correctly, but I copy inserted image, EditText shows me only 'obj'.

View 1 Replies View RelatedI want to have a ViewGroup with another View in it. The user should be able to move the other View around the ViewGroup, and fling it away. However, the inner View shouldnt only move, it should also scale and so on (so we dont restrain ourselves to just movements). I don't really know the best way to implement it.
First I though about using a ViewGroup pretty much as it is (i.e. take advantage of the already-written methods). Then I could do the flinging with an Animation. However, when I move the View around with my finger, wouldnt I have to do a requestLayout, since the View changes size when I move it? Or could I just set a transform?
The other alternative would be to override the draw-method and do most of the work myself. For instance, when the user moves his/her finger, I could get a cache of the View and just paint it on the Canvas (with some transform). However, how would I do the flinging then, without an Animation? I could use a Scroller/VelocityTracker, but What would "drive" the repaints? Which is the best way to do this? Also, I won't have just one View, but a couple of them, so I'd like the solution to be effective.

I have this at the top of my application. When the application starts, the EditText is orange highlighted and has a cursor in it; when the EditText is tapped, the soft keyboard pops up. The user uses it to type into the EditText.
However, when they click the Button, my onClick method fires and does everything it's supposed to, however the soft keyboard stays on screen and the EditText is still highlighted with its cursor.
I also have, at the top of the Button onclick: findViewById(R.id.name).clearFocus();
In spite of this, the EditText does not seem to clear its focus. How do I make the button actually act as if it is submitting the form?
Also, I do not transition to a different Activity on the click of the Button. I suppose that is the typical case, and probably the reason why they don't bother hiding the keyboard. However I want to keep the search box and button at the top of the screen, so I just dynamically fill and add views to the screen when the Button is pressed. How can I achieve my desired behavior?
Every time I put a TextView before an EditText element in a LinearLayout, the EditText does not show. When I don't, it does.
I've narrowed the problem down to the TextView's layout_width attribute. If I give it "wrap_content", it works, but doesn't "block" down, and it appears on the same line as the EditText.

I want to add a view inside a FrameLayout programmatically and to place it in a specific point within the layout with a specific width and height. Does FrameLayout support this? If not, should I use an intermediate ViewGroup to achieve this? My initial idea was to add an AbsoluteLayout to the FrameLayout and place the view inside the AbsoluteLayout. Unfortunately I just found out that AbsoluteLayout is deprecated.
View 2 Replies View RelatedI have a RadioGroup inside of a RelativeLayout. I've got a few RadioButtons for different options, like "Bob", "Joe", and "Fred". However, I need to add an "Other..." option with an EditText right next to a RadioButton in case a user wants to enter "Steve". Is there a way to do this?
View 1 Replies View RelatedI want to implement RadioButton and EditText inside a row of a ListView. I am using an ArrayAdapter to populate the List. But the problem is that when i am selecting a RadioButton and scroll down the list and scroll up again the Radiobutton which had been selected is unselected. Same with the content of the EditText. The text getting removed when I scroll up.
View 2 Replies View RelatedI've spent about 6 hours on this so far, and been hitting nothing but roadblocks. The general premise is that there is some row in a ListView (whether it's generated by the adapter, or added as a header view) that contains an EditText widget and a Button. All I want to do is be able to use the jogball/arrows, to navigate the selector to individual items like normal, but when I get to a particular row -- even if I have to explicitly identify the row -- that has a focusable child, I want that child to take focus instead of indicating the position with the selector.I've tried many possibilities, and have so far had no luck.
Assuming there are other items in the adapter, using the arrow keys will move the selection up/down in the list, as expected; but when getting to the header row, it is also displayed with the selector, and no way to focus into the EditText using the jogball. Note: tapping on the EditText will focus it at that point, however that relies on a touchscreen, which should not be a requirement.ListView apparently has two modes in this regard:
1. setItemsCanFocus(true): selector is never displayed, but the EditText can get focus when using the arrows. Focus search algorithm is hard to predict, and no visual feedback (on any rows: having focusable children or not) on which item is selected, both of which can give the user an unexpected experience.
2. setItemsCanFocus(false): selector is always drawn in non-touch-mode, and EditText can never get focus -- even if you tap on it.
To make matters worse, calling editTextView.requestFocus() returns true, but in fact does not give the EditText focus.What I'm envisioning is basically a hybrid of 1 & 2, where rather than the list setting if all items are focusable or not, I want to set focusability for a single item in the list, so that the selector seamlessly transitions from selecting the entire row for non-focusable items, and traversing the focus tree for items that contain focusable children.
I have an activity A which uses SharedPreferences to share data with a service S, which is called from within A.Now when I call the stopService() method from A, the onDestroy() method in S is not called immediately.I thought that all the activities and services under a single apk run in just one process. Why then does the jump to onDestroy() not take place immediately instead I can see the output from onDestroy() after the further code in the activity A is executed.

View 1 Replies View RelatedI would like to know how to read in an image file which has multiple frames in it. Something like an animated gif file. I would like to perform frame by frame animation with a file of this type. I don't want to have each frame as drawables in the resource directory. Can anyone throw some light on how to perform the above mentioned tasks.
P.S - I have already checked the example in the API demos where an animated gif is read as an object of type Movie. I don't want to read it in as a movie file.
When we tried to display an animated gif image using image view, nothing was displayed on the screen. So, we are suspecting whether image view is not supporting animated gif.
If we place an animated gif file in gallery then thumbnail is not displayed.

But the big deal here is how to hide the keyboard when the user touches or selects any other place that is not an EditBox or the softKeyboard?
I tryied to use the onTouchEvent on my parent Activity but that only works if user touches outside any other view and there is no scrollview.
I tryed to implement a touch, click, focus listener without any success.
I even tryed to implement my own scrollview to intercept touch events but i can only get the coordinates of the event and not the view clicked.
Is there a standard way to do this? in iPhone it was really easy.
I am trying to set up a RelativeLayout within a SlidingDrawer that contains a ViewFlipper that amongst others chooses a view with a text entry field, but when I test the application the space for the entry field and its label appears but the field itself doesn't show.

I am having issue while showing a WebView in an activity in the middle of the screen. I have an activity and I want to show a webview in the center of screen. My activity is transparent so background activity will be visible. Whenever I try to create a webview and add it to activity using setContentView(webview) it always shows the view on the top left corner of the screen. Is their a way to workaround this?I am trying to do this via pure code only.

The translucent background example in API Demos makes the view cover the whole screen. I want to place only a small image and at a specific location (origin not 0,0).
