My app creates a puzzle grid using table layout, tablerows and textviews. I want a user to be able to save this grid to the SD card so that it can be printed or copied or loaded onto another device.
How do you save a view so that when it's printed it will look like it does on the android screen?

View 3 Replies View RelatedI have a png file in my res/drawable-ldpi folder. I'm working in Eclipse with the emulator, but I've tried this on my 2.2.1 Android phone and I get the same behavior. I have an ImageView and I want to set the src programatically, based on a database call. If I just put
Code:
src="@drawable.norusdpyr"
in the Activity's XML file, the file displays fine. BUT, if I put
Code:
String imageresource = "R.drawable." + parsedData[4].toString();
chart.setImageURI(Uri.parse(imageresource));
where parsedData[4].toString() = "nor_usdpyr" I don't see anything. I've also tried
Code:
String imageresource = "android.resource://" + getPackageName() + "/R.drawable." + parsedData[4].toString();
chart.setImageURI(Uri.parse(imageresource));
and
Code:
InputStream is = getClass().getResourceAsStream("/drawable/" + parsedData[4].toString());
chart.setImageDrawable(Drawable.createFromStream(is, ""));
and
Code:
String imageresource = "R.drawable." + parsedData[4].toString();
File file = new File(imageresource);
chart.setImageDrawable(Drawable.createFromPath(file.getAbsolutePath()));
and
Code:
Context context = getApplicationContext();
int ResID = context.getResources().getIdentifier(imageresource, "drawable", "com.KnitCard.project");
chart.setImageResource(ResID);
finally,
Code:
chart.setImageURI(Uri.parse("android.resource://" + getPackageName() + "/R.drawable.nor_usdpyr"));
doesn't work.
None of these work. What am I doing wrong?
I have a class that extends View. I override the onDraw method and allow the user to draw on the screen. I am at the point where I want to save this view as an image. I Can use buildDrawingCache and getDrawingCache to create a bitmap that I can write to the SD card. However, the image is not good quality at a large size, it has jagged edges. Since I have a View and I use Paths I can transform all by drawing to a bigger size. I just don't know how to make the Canvas bigger so when I call getDrawingCache it doesn't crop all the paths I am just transformed. What is happening is I transform all my paths but when I write the Bitmap to file I am only getting the "viewport" of the actual screen size. I want something much bigger.

View 1 Replies View RelatedI'd like to show a png or jpg I downloaded from the next in an image viewer intent, but can't get it to work.
Bitmap bmp = getImageBitmap(jpg);
String path = getFilesDir().getAbsolutePath() + "/test.png";
File file = new File(path);
FileOutputStream fos = new FileOutputStream(file);
bmp.compress( CompressFormat.PNG, 100, fos );
fos.close();
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
startActivity(intent);
I know the bitmap is downloaded ok (use the same routine for supplying it my ImageView instances elsewhere in my app) - I think it wrote to file ok, I can see it on disk and the file size is correct. The intent is launched but an exception is thrown: then the new activity just sits there, blank. How does this work?
