View 1 Replies View RelatedMy objective is to run a glowing animation on an image.I am changing the image alpha to produce this effect.
I have used basic AlphaAnimation provided in android framework but found that its slowing down other animations. So i extended a class from SurfaceView and created a thread to update it. ( Again here, i am manipulating alpha of the image ).
Everything seems fine, except that i am not able to draw a transparent image onto SurfaceView.Its showing black color on the transparent areas of the bitmap.code...
I would like to know what the best way would be to draw a background image (this would be pretty much static) and a foreground object which would move depending on user input in Android?
Sort of like a side-scroller game (when the foregroudn object needs to animate and change a lot more than the background).
I need to know how he takes drawable object. I'm collecting some ImageView objects in array, they have background images that are rather big in resolution so they take lot of memory...
I have read somewhere that it will automatically create image with resolution that my imageView have, so i think it will take less memory than first one. Please tell me, if i set scaleType property, will it scale that image? Will that help me to save memory?
I am wondering if there is a way to draw an image, or edit simple lines in a text box. The entire screen is a textView/ect and i would like to be able to write a sentence then draw an image and write again. By draw i think i would use the Canvas, so basically is there a way to include a canvas in a text view?
Evernote does do this, but to edit an image/draw you need to open another app "Skitch", my goal is to try and do this without any extra apps.
For example:

In Android OpenGL ES, I want to be able to switch textures for a given Rectangle. I have one rect and I put two textures, depending on different conditions. I just want to switch between textures.
I followed this code to create the textures: http://blog.poweredbytoast.com/loading-opengl-textures-in-android but it seems that this is only for one texture.
If I use only one texture, it renders fine, but then I don't know how to tell the rect to use another texture (same rect, different texture). Do I do something like "setTexture" with the ID that is generated in loadTextures()? Do I have to have an array with texture names (numbers) that I then change .. I just don't get it..
We came across a strange behavior. The clip rect of our custom view is getting reset to its entire visible region, if we change the value of another view.
View 4 Replies View RelatedI want to judge whether the touch point(x, y) is in a region or not, the region is from a stardard rect by rotating specified degrees, from example, rotate 30 degrees. There is a class named Region in Android, but as I researched, it just supports standard rect, is there any other way to judge whether a point is in an acclivitous rect? How to do it?

View 4 Replies View RelatedI want to do some automated testcase with Instrumentation . Suggest that my AUT has 2 Activity. After clicking the button in ther first Activity, the second one will be shown with new content base on what we enter in the first Activity.) Instrumentation provides us the function called startActivitySync() and return the Activity object for processing. My question is how we can get the pointer of the second Activity after the it is shown by clicking the button on the first activity.?

View 2 Replies View RelatedI am new to Android development, just reading docs and trying the APIs. I am quit confused how ImageView managed to draw just a part of its content after an invalidate(Rect) invocation.
I've checked ImageView.java, found no other drawing method except onDraw(Canvas), but onDraw(Canvas) only cut the drawable only if it is beyound the view's visible boundary. I also read the implementation of View.invalidate(Rect), I think the key of this function is calling to mParent.invalidateChild(this, r);
However, I think the parent view doesn't know how to draw the child in the given Rect, it finally has to call some method of it child to paint out. Has anybody investigated this part of codes? Would you please give me some guide?
I have an Activity that running on system. I can get the Intent that is used to start the activity. But i don't know how to get the Activity object from the Intent object or something else. Can anyone tell me how to do this??? Note that, I don't use Instrumentation object.

I want to add an unknown number of ImageView views to my layout with margin. In xml, I can use layout_margin like this:
<ImageView android:layout_margin="5dip" android:src="@drawable/image" />
There is ImageView.setPadding(), but no ImageView.setMargin(). I think it's along the lines of ImageView.setLayoutParams(LayoutParams), but not sure what to feed into that.
Does anyone know?
I have an element in the page that under certain circumstances has to get the margin-top increased. as the title says, the element is systematically rendered in the page via xml. Only in certain circumstances, and when that specific view is already rendered, I need to increase the margin. Is it possible at all? workaround?
View 5 Replies View RelatedI was wondering if it's possible to set an automatic/dynamic margin (padding?) between elements in an Android layout without having to do it programmatically?
For example let's say there is a horizontal LinearLayout which is set to android:layout_width="fill_parent" and that contains five elements. Is there a setting that evenly shares the remaining empty space of the LinearLayout to the margins of the child elements?

View 2 Replies View RelatedI'm using a framelayout to position 2 buttons in the center of the screen. I'm anchoring from the center (using layout gravity = center_horizontal) then applying Layout margin left = 50dip and Layout margin right = 50dip to each button. In 2.2 the margins are being drawn much larger than the numbers I've declared (50dip/50dip). It looks more like 125 or 150. Oddly enough, this doesn't appear to be happening with margin bottom/top, only left/right. Is this a bug, or a sign that I'm doing something incorrectly?
View 11 Replies View RelatedIs it possible to add a little bit of space between a RadioButton and the label while still using Android's built-in components? By default the text looks a little scrunched.
<RadioButton android:id="@+id/rb1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="My Text"/>
I've tried a couple of things:
Specifying margin and padding seem to add space around the entire element (button and text, together). That makes sense, but doesn't do what I need.
Creating a custom drawable via XML specifying images for the checked and unchecked states, then adding a few extra pixels to the right side of each image. This should work, but now you are stepping outside the default UI. (Not the end of the world, but not ideal)
Add extra whitespace to the beginning of each label. Android seems to trim a leading space character, as in " My String", but specifying unicode U+00A0, as in "u00A0My String" does the trick. This works, but it seems kinda dirty.
Any better solutions?
I am using the following Layout for the titlebar with a blue backround color
ndroid:textColor, that I get a changed titlebar for my HelloWorlApp, that is fine. But somehow on the left and right side there is some margin and I still can see some Grey from the original titlebar.
What did I wrong?
