I want to change the key width in keyboard at runtime. The constructor of class Keyboard only accepts the layout resource ID. I tried setHeight method, but it didn't work obviously when I checked the code of Keyboard. Any solution? Do I have to implement my own Keyboard

Is there Any way to set the width of the Layout.
Because most of the time it doesn't work?
What happens to the width and height params declared in LayoutParams on configuration change? E.g. if I have an ImageView declared with,
new LinearLayout.LayoutParams(30, 40);
On Configuration Change, does the width become 40 and height 30?
I'm trying to make a timeout gauge bar animation effect:The width of a lengthy colorful bitmap image is decreasing, but not x-scaling.so the image looks not changing and the visible area shrinks.I couldn't find the sole ImageView clipping or masking support in android.then changing the shrink_box's width will clip the portion of the still_image.But I failed to change the width of the view smoothly.I tried to change the LayoutParam.width in applyTransformation() but got an Exception, it seems not allowed. How can I make an Animation that changes the width of the view. OR is there a proper method to achieve the above effect?

View 2 Replies View RelatedI would like change the width of a Horizontal Progressbar programmatically (initial size is set in XML using RelativeLayout...but I would like to dynamically change it based on certain values).
I have tried setMinimumWidth(50) in my code, but that did not make a difference. I have also tried setting 'android:layout_width="wrap_content", but that did not work either.

View 2 Replies View RelatedEvery time that I want to do a Layout, I'm getting a black layout preview then I can drop stuff on it, that's ok, but how can I change the size of that blank surface (xml). The question came because I set a folder layout-large and then when I add a new layout.xml to that folder it came with the same size, as a layout-normal.

View 1 Replies View RelatedI have a layout xml file with a linear layout. One of the children is again a ViewGroup Relative layout. In my java code i want to change the width of this child Viewgroup for my requirements. I tried this
ViewGroup childViewGroup = (LinearLayout)findViewById(childViewGroup);
LayoutParams l = childViewGroup.getLayoutParams();
l.width = 360;
childViewGroup .setLayoutParams(l);
I couldn't do this because findViewById(childViewGroup) doesn't fetch ViewGroups it does only for Views. Note: I cant define a whole new layout.xml for this minor requirement since it is huge layout file and might cause performance overhead. I wanted to just change the width of the child view group in my java activity code.
I have a Gallery with a set of images that was downloaded at run time.I followed the example here:http://www.anddev.org/a_androidwidgetgallery_-_example-t332.html but instead of using i.setImageResource(this.myImageIds[position]);I used i.setImageBitmap(bitmaps.get(position));This doesn't fill the entire width of the screen, only as much as the width specified here:i.setLayoutParams(new Gallery.LayoutParams(150, 150)); When I increase this number, the item scales with it instead of showing more images per the example. I've even tried to scale the images before adding them to the set. Not sure what I'm missing, or where other examples of this might be. Any help would be great.

I am trying to see if anyone knows if it is possible to change the update time of MyLocationOverlay (http://bit .ly /dBIVdj). I have tried subclassing MyLocationOverlay and implementing my own location manager but when that happens I do not see the overlay on the map. I would try overriding the drawMyLocation method however I don't know which canvas to provide the method (since I would be drawing onLocationChange). To summarize, I am looking to do three things in MyLocationOverlay subclass:
1. Change the location update times to whatever I want.
2. Draw the "my location" dot with the radius when the onLocationChanged() method is called.
I've thought about making my own special class with special overlay -- but I feel like there has to be a better method to get what I want out of this class.
I am using android.intent.action.LOCALE_CHANGED to detect language changes and update my widgets. Is there something analogous for date and time format changes? I don't see anything, but I could be just blind.

View 6 Replies View RelatedI am using a custom title view in my application for each activity. In one of the activities, based on button clicks I need to change the custom title view. Now this works fine every time when I make a call to setFeatureInt.
But if I try to update any items in the custom title (say change the text of a button or a text view on the title), the update does not take place.
Debugging through the code shows that the text view and button instances are not null and I can also see the custom title bar. But the text on the text view or the button is not updated. Has anyone else faced this problem? How do I resolve it?
