Apps PNG file won't display in ImageView when src is set programatically

[mellomel70]

I 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

src="@drawable.norusdpyr"

in the Activity's XML file, the file displays fine. BUT, if I put

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

 String imageresource = "android.resource://" + getPackageName() + "/R.drawable." + parsedData[4].toString();
    chart.setImageURI(Uri.parse(imageresource));

and

InputStream is = getClass().getResourceAsStream("/drawable/" + parsedData[4].toString());
chart.setImageDrawable(Drawable.createFromStream(is, ""));

and

String imageresource = "R.drawable." + parsedData[4].toString();   
    File file = new File(imageresource);
    chart.setImageDrawable(Drawable.createFromPath(file.getAbsolutePath()));

and

Context context = getApplicationContext();
    int ResID = context.getResources().getIdentifier(imageresource, "drawable", "com.KnitCard.project");
    chart.setImageResource(ResID);

finally,

 chart.setImageURI(Uri.parse("android.resource://" + getPackageName() + "/R.drawable.nor_usdpyr"));

doesn't work.
None of these work. What am I doing wrong? Thanks!

In the layout XML, you should use a / instead of a .

src="@drawable/norusdpyr"

Or in an activity, set the image like this:

chart.setImageDrawable(R.drawable.norusdpyr)

The . instead of a / was a typo on my part. However, the setImageDrawable method takes a parameter of type Drawable, so my question would be how to I convert a string that I build dynamically into a Drawable? At any rate, I've found a solution using setImageResource:

 [/LEFT]
[SIZE=2]String imageresource = parsedData[4].toString();
[/SIZE][LEFT]Context context = getApplicationContext();
int ResID = context.getResources()
.getIdentifier(imageresource, "drawable",
context.getPackageName());[/LEFT]
chart.setImageResource(ResID);
[LEFT]

Thanks for your help! ​
