Cómo mostrar una imagen usando ImageView en Android

I am looking for the way to assign image src to image view control. I read few example and they says something src="@drawable\image" but didn't understand this, also I want to assign image src at runtime by java code also want to apply default image in XML.

If you want to display an image file on the phone, you can do this:

private ImageView mImageView;
mImageView = (ImageView) findViewById(R.id.imageViewId);

If you want to display an image from your drawable resources, do this:

private ImageView mImageView;
mImageView = (ImageView) findViewById(R.id.imageViewId);

Encontrarás el drawable folder(s) in the project res folder. You can put your image files there.

Thanks Michell, I created an Images folder in my project, inside of it there is a png image Black_x.png, So what should be the path here to decode image, it should be Images\Black_x.png ? - BreakHead

You should put your images in the drawable folder(s) in /res/. It'd be a good idea to use different sized images for each of the folders (i.e. hdpi and mdpi). Then use setImageResource(R.drawable.black_x) - Michell Bak

Once again Thanks, but when I am using R.id.imageViewId here I am not getting any id option means when I type R.id it says id is invalid - BreakHead

I really don't know how to explain it otherwise, as it's quite simple. Put an image file in your /res/drawable/ folder (if there's no drawable folder, use drawable-mhdpi or similar). Android will automatically create a reference to that image with its filename as the ID - i.e. R.id.black_x if your image file is called "black_x.jpg". - Michell Bak

@MichellBak and when does it create the ID file? - imsrgadich

You can set imageview in XML file like this :

    android:src="@drawable/imagep1" />

and you can define image view in android java file like :

ImageView imageView = (ImageView) findViewById(R.id.imageViewId);

and set Image with drawable like :


and set image with your memory folder like :

File file = new File(SupportedClass.getString("pbg"));
if (file.exists()) {
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inPreferredConfig = Bitmap.Config.ARGB_8888;
        Bitmap selectDrawable = BitmapFactory.decodeFile(file.getAbsolutePath(), options);
      Toast.makeText(getApplicationContext(), "File not Exist", Toast.LENGTH_SHORT).show();

In res folder select the XML file in which you want to view your images,

        android:src="@drawable/imagep1" />

debe ser @drawable/image dónde imagen could have any extension like: image.png, image.xml, image.gif. Android will automatically create a reference in R class with its name, so you cannot have in any drawable folder image.png and image.gif.

Drag image from your hard drive to Drawable folder in your project and in code use it like this:

ImageView image;

image = (ImageView) findViewById(R.id.yourimageviewid);
