Android :: Drawing A Nine Patch Image

Nov 29, 2009

I'm trying to create on of these images, but Eclipse won't accept it once I've used the draw9patch tool. I've found other people having the same problem, and saw this comment: I discovered later that the problem I was having was caused by the image not being exactly true to the nine-patch spec as defined in the documentation. Once I fixed the image to have a clean (i.e., no gradients etc) one pixel border it was fine. "'m not much good when it comes to image design. What does this mean, how do I create my original png file to meet the specification for Nine Patch?

Android :: To Make EditText Look Like TextView But Still Behave Like EditText

May 17, 2009

I want an EditText to look like TextView but still behave like EditText. I've tried applying TextView style to my EditText in my layout.xml file, like this:

CODE:............

But I get an error within xml editor: "Error: No resource found that matches the given name (at 'style' with value '@android:style/ Widget_TextView')." It is strange because @android:style/ Widget_TextView definitively exists - I double checked it in code via android.R.style.Widget_TextView. Another strange thing is that I don't get android:style offered in the xml editor while typing? There is android:id, android:text and everything else.. but not android:style?

I consider the hard way (making EditText look like TextView) to be: extending EditText and overriding it's onDraw method.

Android :: ScrollView With EditText - Scrolling In EditText

May 14, 2010

Our app (WordPress for Android) uses a ScrollView for the new blog post view. The issue is that if a user writes a lengthy blog post in the EditText, they are unable to scroll inside of the EditText because the ScrollView seems to be taking over the scrolling action, even when you are in the EditText.

Here's the layout XML (the EditText in question is @id/content):

Android :: Placing A TextView Before EditText Element In Android Layout XML Causes EditText Not To Show

Jul 29, 2010

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.

Android :: Android - EditText And Button - When Click Button - Unfocus EditText And Hide Soft Keyboard

Jun 24, 2010

CODE:............

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?

Android :: Drawing And Animating?

Nov 5, 2010

This is more of a question about animating than a specific problem coding. i need to fill in the broad strokes left by the research i've been doing.

What i'm trying to do:

The activity should load with only the a togglebutton visible. when the button is touched, a png will be animated to a certain position relative to the togglebutton. also, another button will slide in from off screen and slide off if/when the togglebutton is pressed again.

What i can't figure out:

I can draw an image, but only via xml. creating an imageview and setting the background programmatically does nothing.

When i draw from xml, i can't move the image when the togglebutton is pressed like i want to. when i call getPositionOnScreen() i get a null pointer, even though the complier can see i'm referring to the imageview described in both xml and in code.

I'm calling getPositionOnScreen because via xml, i have the image positioned behind the togglebutton so that it's not visible until the button has been pressed and the image starts moving. the idea is that with different screen sizes i won't know exactly where the view is until runtime. getPostionOnScreen allows me to get the coordinates of the imageview so i know where it has been positioned. when i have a start position, can tell it to "move up" on the screen from behind the togglebutton by simply adding to x or y until it's where i want.

This is the code to draw the image (inserted in the onCreate method).

CODE:.......

This is the code i'm using to animate. when the button is clicked, it calls this method on the view from the listener.

CODE:...............

I'm well aware that this is horribly wrong and won't work. what i need to understand is why.

Android : App That 'animates' Drawing?

Apr 18, 2010

I'm trying to learn about Android programming by rewriting a C app I've moved from DOS to X-windows to Windows as a learning tool. It's just a silly little app that draws symmetrical 'game of life' patterns on the screen in a kaleidoscopic fashion. It's structured so that the patterns do their own animations. I.e. there's a 'Life' class that produces the next generation and redraws itself from the center outward, inserting delays to produce a kaleidoscopic effect.

I've got it so that the patterns draw - I took the LunarLander sample as a starting point, and an drawing on a SurfaceView. But my problem is with timing the 'animations'. I'm not doing traditional animation, where I build a whole frame and then draw it, but the surface seems to want to draw itself completely on each iteration of my loop, so my inserted sleep's don't insert delay in the right places.

So my questions:

1. Is there a more direct way to write to the screen than via a SurfaceView? If I did that, would the various steps of my 'animation' occur as I drew them, producing the desired effect. 2. If such a drawing method exists, would I be wasting my time learning how to use it? 3. What's the 'standard' way to do this kind of animation?

Android :: Return Value Of Get Drawing Cache

Jun 17, 2009

From the JavaDoc, it said it returns 'a bitmap representing this view or null if cache is disabled'. My question is what if the View is longer than the phone screen (you need to scroll vertically), what does the bitmap return? * only the visible portion of the view * everything the view has (both visible + invisible part)

Android :: Having Offscreen Drawing Of A View

May 26, 2010

I'm having a small problem with drawing a View offscreen to a Bitmap. The View is created using LayoutInflater.inflate(int resource, ViewGroup root) with null passed to the root parameter. The View has a fixed size (200x180 pixels). I can create a Bitmap for this View either by using the method View.getDrawingCache() or by calling View.draw(Canvas canvas) using a Canvas that in turn has a backing Bitmap. This works fine if the View doesn't change after the inflate. However, if I have a TextView inside my View that I will update, the size of the TextView is never updated regardless of what method I call on the View (requestLayout(), forceLayout() invalidate() etc.). If I display the View on screen directly, everything works fine (sizes are updated as needed, etc.). What is the correct way of drawing Views off screen and being able to update their layout when needed?

Android :: Why Drawing In View Not Take Effect?

Mar 31, 2009

I'm trying to create a custom widget which looks lick HTML table. I chose to derive from TableLayout, which is the subclass of ViewGroup and View. What's confusing me is that the drawing I put into my override of View.onDraw did not take effect, until I moved the codes to the override of ViewGroup.dispatchDraw. I know dispatchDraw is a good place to draw something, but I'm just wondering why there's such difference in my practice?

Android :: Drawing Text Upside Down

Apr 5, 2010

I'm trying to build a custom clock view in Android. See image http://twitpic.com/1devk7.So far to draw the time and hour markers I have been using the Canvas.rotate method to get the desired effect. However, notice that it is difficult to interpret the numbers in the lower half of the clock (e.g. 6 or 9?) because of the angle in which they are drawn.When using drawText, is it possible to draw the text at 45/90/180 degrees so that all text appears upright when my onDraw method has finished?

Android :: Drawing On WVGA Screen?

Jan 7, 2010

I wrote a reading software. I implemented the page turning effect when user tap the screen to turn to next/pre page. The display is ok on G1 (320X200 size) but it can not works well on Droid(480*854 size), the font looks a litter fuzzy, not clear as G1. I explain my codes for page turning:

1) create a canvas A

2) create bitmap.

3) set bitmap on canvas A

4) draw the new page content on canvas A

5) the current showing page has been saved in bitmap before since we do from step 1) to setp 4),

6) In order to implement the turning effect of scrolling from left to right, I draw the old bitmap part and draw the new bitmap part until the whole new bitmap has been drawn. all of bitmaps are drawing by canvas.drawBitmap() in onDraw() function.

7) when step 6) is done, it means the new page has been shown on screen, and the bitmap has been saved to use in next page turning.

The above is the whole actions for my page turning. On G1, no problem. But on Droid phone, the font is not clear, I tried if I directly draw text by canvas in OnDraw() not through bitmap, It is ok, but it can not implement the page turning effect that I need. I don't know why, could you please help me to take a look and tell me where is wrong or miss some steps?

Android :: How To Add A Line Drawing To ListView

When I try extending the View class to a subclass that will underline portions of the text drawn by ListView, the code compiles okay but results in a runtime exception apparently due to an improper class cast. Does anyone see what I've done wrong or have suggestions about getting access to the Canvas of ListView items so portions of text can be underlined?

Here is the code, which is the Efficient Adapter View/List example from ApiDemos with an added UnderlinedView class.
