Android :: Draw Transparent Lines On Bitmap Via Touch Input
Jul 23, 2010I am working on a paint application for Android. Now I want to implement an eraser to allow erasing parts of a loaded bitmap by using touch input and making the bitmap transparent along the finger's path.
A very good example of what I try to achieve is shown in the application Steamy Window for Android. Steamy Window simulates a fogged window, where a user can wipe parts of the fog via touch input.
UPDATE: I have posted the most important sections of my current code below. I am not really happy with it for the following reasons:
Drawing is quite sluggish. What can I improve here?
I am looking for a way to use an alpha mask in order to set the pixel transparency/alpha of the pixels as I want to simulate a paint brush. Any suggestions how this could be achieved?

Android :: Simplest Way To Draw Pixels Lines / Circles On A View?
Aug 14, 2010What is the simplest way to draw pixels, lines and circles on a View?I want to move a cross cursor around, so nothing particularly intensive.I thought I could extend SurfaceView and add it to an XML and it would just work, but it just appears black, however, when I look at the layout view of localmap.xml in eclipse, the graphics appear as expected. Any ideas? My onDraw is never called on the emulator, and even calling invalidate on the class makes no difference. I shall keep trying but can anyone see anything I've missed? or is there a better way entirely? Code...

Nov 11, 2010I'm writing an app that shows in google maps pipes and valves(lines and points). For that i've two classes.
One extends from ItemizedOverlay, and i add to map overlay one for each category of valve, and each one can have more than one item.
The second extends from Overlay, and in the draw method y draw the line with the method drawline of the canvas.
The problem i've is that the lines are drawn over the ItemizedOverlay items, no matter the order i add them to the mapView.getOverlays().
I want the lines on the bottom of all overlays. is there a way to do that.
Android :: Draw 9 Patch Tool - What Is Meaning Of Black Lines Outside Figure
Nov 20, 2010I tried enough to find in google & android this question. Also did several trials & errors, but couldn't get this question. was learning Android's "Draw Nine Patch" images. One basic I know is that, whatever image you process must be in .png format (if it's already in .9.png then it will be ignored by tool). However, couldn't understand what it literally means by "stretchable patches" ? what exactly happens when you draw black dots outside the .png image ? (preview pane shows changes happening, but I am unclear on how it makes those)When I draw black dots in left/top sides of image it shows some changes in preview; but why isn't there any effect when you do the same on right/bottom side of the image ? why this tool is used primarily for background, when we try to process on the image itself ?i am trying to modify a simple button.png (given in android sdk). Whenever I use this tool & draw black lines, it reduces the size of the image instead of 'stretching' it! Why ?What is the significance of options given below like, "show lock", "show content", "Patch scale" and so on ?I apologize for asking so many questions, but in Android online docs they haven't explained well for novice. If someone can answer these, it will become ready reference for all the begineers who search this forum.
View 2 Replies View RelatedHow To Draw Image Or Edit Simple Lines In Text Box
Jan 8, 2013I 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:
Hello

Aug 7, 2010I am very new to android development and have been trying to draw a square comprised of multiple smaller rectangles of different colours... Like a Mosaic essentially. Basically at the moment I am reading values from a file which assigns the colour to the smaller Rects. I am using a pair of nested for loops to try to draw the small Rects sequentially, line by line. However when the program finishes there is only one small Rect drawn which is the last one to be drawn and its colour corresponds to the first value read from the file. Here is some of my code to show you what I mean:
public SnapshotDraw(Context context) {
super(context);
for(int a = 0; a < 63; a++){
for(int b = 0; b < 63; b++){

Android :: Multiple EditText Controls And Focus
Jun 9, 2010I have an activity with two edittext controls. I am calling the requestFocus on the second edittext field since by default the focus goes to the first edittext control. The focus appears to be in the second edittext field (the second one gets the highlighted border), but if we try to enter any characters using the hardware keyboard the text appears in the first edittext control.
View 1 Replies View RelatedAndroid :: Multiple EditText Not Getting Focus - No Soft Keyboard?
Sep 2, 2009The home screen of my Android application has three EditText views, meant to be used as three different search functions, each with a "Search" button. The app works perfectly on the device (G1) when using the trackball: I can move between the EditTexts with the trackball, all the events fire as expected, I can enter text using the physical keyboard in the selected EditText, Enter correctly submits the proper search, etc.
However, I can't switch between the EditText views using touches - only by using the trackball. Touches seem to be completely ignored by the EditText. Touches do fire for the buttons, but very hard - takes a lot of tries to make a touch register. In the simulator, clicking on any EditText does nothing - the first one always remains selected, and I never get a soft keyboard. This is all inside a TabHost - I've read there are some problems with that configuration, but it sounds like a slightly different issue (the EditText doesn't seem to lose focus - everything works perfectly with the trackball).

View 1 Replies View RelatedAndroid :: To Make EditText Look Like TextView But Still Behave Like EditText
May 17, 2009I 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 :: Android - EditText And Button - When Click Button - Unfocus EditText And Hide Soft Keyboard
Jun 24, 2010CODE:............
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?
