Create a Bitmap/Drawable from File Path

Create a Bitmap/Drawable from file path

Create bitmap from file path:

File sd = Environment.getExternalStorageDirectory();
File image = new File(sd+filePath, imageName);
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
Bitmap bitmap = BitmapFactory.decodeFile(image.getAbsolutePath(),bmOptions);
bitmap = Bitmap.createScaledBitmap(bitmap,parent.getWidth(),parent.getHeight(),true);
imageView.setImageBitmap(bitmap);

If you want to scale the bitmap to the parent's height and width then use Bitmap.createScaledBitmap function.

I think you are giving the wrong file path. :) Hope this helps.

Android get image to Bitmap from filepath

Use This Method to get Bitmap from Filepath

public Bitmap getBitmap(String path) {
Bitmap bitmap=null;
try {
    File f= new File(path);
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inPreferredConfig = Bitmap.Config.ARGB_8888;
    bitmap = BitmapFactory.decodeStream(new FileInputStream(f), null, options);
    image.setImageBitmap(bitmap);
} catch (Exception e) {
    e.printStackTrace(); 
}
return bitmap ;
}

Getting bitmap from file path

You are not incrementing imageCounter, so it actually is an endless loop.

An enhanced for loop is less error prone:

for (String uri : imageUris) {
    ...
    Bitmap bitmap = BitmapFactory.decodeFile(uri);
    ...

How to get path from image on drawable folder and set as image view, Bitmap?

You can save Reference Id R.drawable.img_name as integer rather than saving path.

When you need to manipulate this drawable you can use that id instead of R.drawable.img_name.

If you need a bitmap from this drawable follow this

Bitmap icon = BitmapFactory.decodeResource(context.getResources(),
                                       saved_id);

creating BitmapDrawable from path

Ok... I think I have a handle on your problem now. Like I said, you can't access your drawables via a path, so if you want a human readable interface with your drawables that you can build programatically, declare a HashMap somewhere in your class:

private static HashMap<String, Integer> images = null;

Then initialize it in your constructor:

public myClass() {
  if (images == null) {
    images = new HashMap<String, Integer>();
    images.put("Human1Arm", R.drawable.human_one_arm);
    // for all your images - don't worry, this is really fast and will only happen once
  }
}

Now for access -

String drawable = "wrench";
// fill in this value however you want, but in the end you want Human1Arm etc
// access is fast and easy:
Bitmap wrench = BitmapFactory.decodeResource(getResources(), images.get(drawable));
canvas.drawColor(Color .BLACK);
Log.d("OLOLOLO",Integer.toString(wrench.getHeight()));
canvas.drawBitmap(wrench, left, top, null);

Convert a File Object to Bitmap

You should be able to use BitmapFactory:

File mSaveBit; // Your image file
String filePath = mSaveBit.getPath();  
Bitmap bitmap = BitmapFactory.decodeFile(filePath);
mImageView.setImageBitmap(bitmap);

How to convert a Drawable to a Bitmap?

This converts a BitmapDrawable to a Bitmap.

Drawable d = ImagesArrayList.get(0);  
Bitmap bitmap = ((BitmapDrawable)d).getBitmap();
