setImageBitmap gets Syntax Errors

Question

I am trying to take a Bitmap and display it in an ImageView.

ImageView iv = new ImageView(this);

Bitmap bMap = BitmapFactory.decodeFile("/res/drawable/" + imageFileName);
iv.setImageBitmap(bMap);

That's my code for it. I create an ImageView and a Bitmap. I want to display my Bitmap in my ImageView. But I always get these two errors on the iv.setImageBitmap(bMap); statment

Syntax error on token "bMap", VariableDeclaratorId expected after this token    
Syntax error on token(s), misplaced construct(s)    

Does anybody has an idea why this happens and what i have to change?

Answer 1

In OP's pastebin code I've found the following snippet:

String imageFileName =getIntent().getStringExtra("imageFileName");
//String bildquelle = "R.drawable." + imageFileName;

public class ImageChange extends Activity {          
  ImageView iv = new ImageView(this);
  String bildquelle = "R.drawable." + imageFileName;
  int id = getResources().getIdentifier(bildquelle, "drawable", getPackageName());

  Bitmap bMap = BitmapFactory.decodeResource(getResources(), id);
  //Bitmap bMap = BitmapFactory.decodeFile("/res/drawable/" + imageFileName);
  iv.setImageBitmap(bMap);
}

There are a couple of problems with this including:

1. The code is not inside a method body.
2. The code is a Activity subclass.
3. The code improperly calls getResources().getIdentifier(...).

Instead of the above code I suggest MERGING the rest of activity with the following:

public class BildAnzeigen extends ActionBarActivity {

  ImageView iv;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_bild_anzeigen);
    iv = (ImageView) findViewById(R.id.my_image_view); // replace the id with the one from layout definition

    handleIntent(getIntent());
  }

  private void handleIntent(Intent intent) {
    String imageFileName = intent.getStringExtra("imageFileName");
    int id = getResources().getIdentifier(imageFileName, "drawable", null);
    Bitmap bMap = BitmapFactory.decodeResource(getResources(), id);
    iv.setImageBitmap(bMap);
  }
}

Note: This will not work if the images are not compiled within your apk. There's no way to add anything to drawables after building. It just doesn't work that way.
