Question

I have been looking all over stackoverflow to find a solution, but I haven’t found it. So now I want to say sorry if duplicate is found. Now that I have said that, let’s get some code and problems:

I am trying to load an ImageView into my Activity, but I keep getting a nice blue debug log in my logcat saying "imageview == null"

if (imageview == null) { 
    Log.d(TAG, "imageview == null");
 } else {
    imageview.setImageBitmap(bm); }`

which just checks if my ImageView is null or not (and sets an image into it if not null). I try load it in the onCreate method:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.confirmpicture);
    String str = getIntent().getStringExtra("GalleryImage");
    Log.i(TAG, "Got " + str + " from the intent");
    Bitmap bm = BitmapFactory.decodeFile(str);
    imageview = (ImageView) findViewById(R.id.galleryPicture);
    if (bm != null) {
        if (imageview == null) {
            Log.d(TAG, "imageview == null");
        } else {
            imageview.setImageBitmap(bm);
        }
    } else {
        Log.d(TAG, "Bitmap not decoded");
    }

My head keeps asking me: “Did you declare the ImageView in the xml file, you fool?” and I keep checking the xml file which contains

<ImageView
    android:name="@+id/galleryPicture"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_below="@id/confirmText"
    android:contentDescription="description comes here...." />

I am targetting API 8 (Android 2.2) and I have been trying to fix this problem about loading the ImageView for days now. Fixed now

You should write android:id="@+id/galleryPicture" in the xml file, not android:name="@+id/galleryPicture". There is no view with id galleryPicture in the layout file you created.
