Android :: Why Bitmap Is Placed On An An Imageview Incorrectly?
Nov 24, 2010this problem has been bothering me for days and I cannot figure out why on earth it is happening. I have a method that detects for a face, if a face is detected, the method will draw a rectangle on a canvas along the face.That part works fine.The problem is, when it displays to the image_view in my xml file, it will display on the far left middle of the image view, in a box, rather than in the center with the width as fill_parent.I thought of a possible workaround : to set the bitmap as a bitmapdrawable, but canvas only draws to bitmaps, so I can get the bitmapdrawable in the middle, but with no red box around it.I commented out my testing of bitmap drawable, and left it as what I have now...it only displays to my xml in the far left of the image_view.

May 14, 2010I'm working on an Android application that needs to download an image and display it inside an image view. The Bitmap is passed to the main java file and added to the image view like this:
CODE:.......
This works, except that the left side of the image disappears off the screen. The ImageView is in a ScrollView and the scroll view maintains the correct size. This means that there is black space to the right in the ScrollView and the image is cut off to the left.
The XML for the ImageView is this:

Any idea why my image is being cut off?

Sep 15, 2010I was looking over this code about extending an ImageView: http://marakana.com/forums/android/examples/98.html
And i was wondering how can i add the new View to an existing xml layout file, along with some other views.
Already i did this inside my main linear layout:

But the problem is that this way the onDraw method doesn't get called.
Maybe some examples where you combine CustomViews with xml layout.
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 : Bitmap Memory Handling With ImageView.setimage
Jun 4, 2010I've read a lot of previous messages on this topic but couldn't find universal agreement on the whole. I can't reproduce this in house, but a customer got an OutOfMemoryError when using an icon chooser dialog.
This dialog is much like the Grid1 example - only it's in a dialog.
The bitmap memory seems to run out after running the dialog a few times for a customer, resulting in java.lang.OutOfMemoryError: bitmap size exceeds VM budget. Should I try to call recycle on the bitmap from an ImageView when I reuse the view? Or would the ImageView do that anyway?
But even if I do that, that's only a small portion of the bitmaps because most of them are seen without scrolling. The Adapter and the GridView are both local variables and therefore shouldn't be referenced after the dialog is dismissed.
I do believe that it should be possible to use many bitmaps in an app - Google Maps does it, Picture Gallery does it. But maybe I need to learn more rules. Some say you should call bitmap.recycle, some say you shouldn't have to. Many say calling gc.collect will make it worse, etc.
Android : Preventing Scale On Bitmap Created In Execution Time For ImageView
Sep 23, 2010I have a ImageView acting as a top banner on top of a webview. The image of this banner is created in execution time dependending on the resolution of the device. The height of the banner is always the same for each resolution. The only thing that changes is the width, which changes according to the orientation. But, since the width changes and the height doesn't, I end up having sort of 2 images with different proportion. And this is way the scale down/up won't work out for me.
Another problem is that everytime the user rotates the screen, the banner image is created again but Android seems not to update the image and thus I have a banner missing part of it.
I thought about having a real big image that will fit for both landscape and portrait orientation. But this seems not to be a good idea since Android keeps resizing the image everytime so it will fit on the space of the ImageView.
I'm running out of ideas here. Can someone suggest something?
Android :: How To Change Size Of Bitmap Contained In ImageView / Without Affecting Surrounding View

View 1 Replies View RelatedAndroid : 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.

Then I add an drawable to the ImageView logo in onCreate. I've managed to show either the ListView or the ImageView but never both of them in the same LinearLayout. Is it possible to add other views together with a ListView?
