Android :: Converting Bitmap To Grayscale
May 20, 2009I would like to convert a Bitmap to a grayscale array of bytes (one byte per pixel). At the same time I want to just crop at section from the middle. Having looked though the various api's it is not clear to me what the best way would be.
1) What is ALPHA_8? is that grayscale? I have a feeling that the grayscale effect should be done via some "saturation" on the paint object, right?
2) once I have the Bitmap in grayscale and the right size, what is the best way to get that to a byte[] of pixels (one byte per pixel)?
Android :: Converting A TextView - Bitmap - ImageView - Nothing's Showing Up
Nov 12, 2010I started a test project just to get this down. No changes to main.xml. I want to create a widget-sized ImageView (80x100) that contains a Bitmap converted from a TextView. Yes, that sounds very roundabout but this is just for testing; in the end I want the ImageView to have a background image and multiple TextViews. I'm not sure exactly what I'm doing wrong, but nothing is being pushed to the screen.
Is it a problem with declaring the TextView/ImageView and passing it "this" in the constructor? Is it a problem with my layoutParams? Here is the code:
package com.doaf.testproject;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView; Code...
I'm relatively new to Android, and pretty lost with this one.
Android :: Converting Binary JPEG Data To Bitmap

How To Convert ASCII Character To Decimal Number In Android
Jul 28, 2013I'm working on an Android app. I have a TextView which contains an ASCII character. This character changes every 2 hours. I need to be able to read this character and convert it to decimal number, and then write it to an another TextView. So let's say the character is "[" and it's decimal value is 91. 2 hours later this character changes to "U" and it's decimal value is 85.
what kind of code should I use in my app to be able to convert ASCII character to decimal number?
Android : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory
Jul 21, 2010I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?
Android :: Create Mutable Bitmap From Camera - Draw Another Bitmap On Top - And Save It
Apr 2, 2009I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.

Motorola Droid :: Question Mark On Non ASCII Characters In Text Messages
Aug 22, 2010I have a Droid with Android 2.1. I am on a CDMA network. I send messages to some people on a GSM and when we use non-ascii characters, like ± or ¡ or Japanese and such, over sms, the other end gets them as question marks �. I don't know anybody on a CDMA network so I can not test if the problem would be there too. I don't know if it is a problem between the networks or something wrong with my phone or what. Finding information in google has proven unsuccessful. Though I found some text naming it a 'common' problem.

Apr 12, 2010I'm compiling using android tools without eclipse.
I compile launching "ant debug" from command line.
I have found many many instructions around the web about how to remove with annoying warning, but I haven't been able to make any of them work.
I've tried -D option, I've tried randomly tweaking build.* files, I've tried exporting an environment variable... nothing.
I guess some of these methods just don't work, and some others would work but I've been doing them incorrectly. Anything is possible and I can't stand it any more: any advice on how to do it?

Jul 8, 2010I have a JSON Object with a latitude and longitude String on which I get the values doing this: String latitude = picInfo.getString("latitude"); String longitude = picInfo.getString("longitude");Then I convert them to floats like this: float latInt = Float.valueOf(latitude).floatValue(); float longInt = Float.valueOf(longitude).floatValue();And place them on a GeoPoint like this: GeoPoint X = new GeoPoint((int) (latInt*1E6),(int) (longInt*1E6) ); Debugging this values I can see JAVA approximates the values, is there anyway to keep them exactly the same?
View 6 Replies View RelatedAndroid :: Converting Canvas To Drawable?
Sep 5, 2009Is it possible to convert a Canvas to Drawable?I may be really off in my solution, so if you have a better suggestion, please do tell me. This is what I'm trying to do.I'm trying to create a custom RadioButton. to set different states of the radio button, I need to use this parameter and one of the parameter to addState is Drawable. I know I can easily provide an image file and use it as a Drawable, but I want to do some image manipulation to the image before using it.There is a tutorial in ApiDemo called AlphaBitmap. It uses the onDraw method of a View to change a PNG file to full red and draw something with a gradient. So I customized it to shade an icon with gradient. So the problem now is that this is a View, and the View works perfectly fine if I add this View to the main view. But i want to convert this View to Drawable so I can use it as one of the parameter in addState. What I really want to achieve is to have different colour shades for different state of the RadioButton without providing different images to do so.

Aug 12, 2010Is there a way to convert milliseconds to minutes using java.util.concurrent.TimeUnit?
This answer seems to suggest that you can use a TimeUnit.MILLISECONDS.toMinutes() method, and the documentation suggests that you could use the TimeUnit.MILLISECONDS.convert() method with TimeUnit.MINUTES - the problem is that neither TimeUnit.MINUTES or TimeUnit.MILLISECONDS.toMinutes() seem to actually exist.

Android :: Downloading Images And Converting To Bitmaps
Jun 16, 2010I am working on an application that downloads images from a url. The problem is that only some images are being correctly downloaded and others are not. First off, here is the problem code:
public Bitmap downloadImage(String url) {
HttpClient client = new DefaultHttpClient();
HttpResponse response = null;
try {.......................................
So what I have is a method that takes the url as a string argument and then downloads the image, converts the HttpResponse stream to a bitmap by means of the BitmapFactory.decodeStream method, and returns it. The problem is that when I am on a slow network connection (almost always 3G rather than Wi-Fi) some images are converted to null--not all of them, only some of them. Using a Wi-Fi connection works perfectly; all the images are downloaded and converted properly. Does anyone know why this is happening? Or better, how can I fix this? How would I even go about testing to determine the problem?
