When we use a default camera application the photos are fine. I know there are some issues in android 1.5, also some hardware issues in some devices, however is there any workaround or settings to overcome this ?

I tried to create a bitmap from pre created Picture object by BitmapFactory.decode Stream and failed. Seems like Picture object is unrecognized format by Bitmap factory. Just wondering is there any method to do the conversion?

I have some png files that I am applying a color to. The color changes depending on a user selection. I change the color via 3 RGB values set from another method. The png files are a random shape with full transparency outside the shape. I don't want to modify the transparency, only the RGB value. Currently, I'm setting the RGB values pixel by pixel (see code below).I've come to realize this is incredibly slow and possibly just not efficient enough do in an application. Is there a better way I could do this? Here is what I am currently doing. You can see that the pixel array is enormous for an image that takes up a decent part of the screen
View 1 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.)

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 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?
I 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.
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.

View 8 Replies View RelatedI'm battling with Android's retarded layout system. I'm trying to get a table to fill the screen (simple right?) but it's ridiculously hard.
I got it to work somehow in XML like this:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent">
<TableRow android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1">
<Button android:text="A" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
<Button android:text="B" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
</TableRow>
<TableRow android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1">
<Button android:text="C" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
<Button android:text="D" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
</TableRow>
However I can not get it to work in Java. I've tried a million combinations of the LayoutParams, but nothing ever works. This is the best result I have which only fills the width of the screen, not the height:
table = new TableLayout(this);
// Java. You suck.
TableLayout.LayoutParams lp = new TableLayout.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.FILL_PARENT);
table.setLayoutParams(lp); // This line has no effect! WHYYYY?!
table.setStretchAllColumns(true);
for (int r = 0; r < 2; ++r)
{
TableRow row = new TableRow(this);
for (int c = 0; c < 2; ++c)
{
Button btn = new Button(this);
btn.setText("A");
row.addView(btn);
}
table.addView(row);}
I have two questions actually:
Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise... which one is better?
If I want to draw something transparent over a bitmap, how would I go about doing it?
If I want to overlay one transparent bitmap over another, how would I do it?
My goal is the draw a bitmap onto another bitmap but rotated 90 degress. whats the most efficient way to do that. My current method is as follows which is horribly bad because it creates a new bitmap every time.

Why my ListView shows only the first item and does not fill the screen?
