¿Mostrar vista de imagen desde la ruta del archivo?

Necesito mostrar una imagen usando solo el nombre del archivo, no del ID del recurso.

ImageView imgView = new ImageView(this);
imgView.setBackgroundResource(R.drawable.img1);

Tengo la imagen img1 en la carpeta dibujable. Deseo mostrar esa imagen del archivo.

¿Cómo puedo hacer esto?

Labeeb tiene razón acerca de por qué necesita configurar la imagen usando la ruta si sus recursos ya están dentro de la carpeta de recursos,

Este tipo de ruta es necesaria solo cuando sus imágenes se almacenan en la tarjeta SD.

Y pruebe el siguiente código para configurar imágenes de mapa de bits de un archivo almacenado dentro de una tarjeta SD.

File imgFile = new  File("/sdcard/Images/test_image.jpg");

if(imgFile.exists()){

    Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());

    ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);

    myImage.setImageBitmap(myBitmap);

}

E incluya este permiso en el archivo de manifiesto:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Creo que puedes usar esto

Bitmap bmImg = BitmapFactory.decodeFile("path of your img1");
imageView.setImageBitmap(bmImg);

También puedes usar:

    File imgFile = new  File(“filepath”);
    if(imgFile.exists())
    {
        ImageView myImage = new ImageView(this);
        myImage.setImageURI(Uri.fromFile(imgFile));

    }

Esto hace la decodificación de mapa de bits implícita para usted.

String path = Environment.getExternalStorageDirectory()+ "/Images/test.jpg";

File imgFile = new File(path);
if(imgFile.exists())
{
   Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
   ImageView imageView=(ImageView)findViewById(R.id.imageView);
  imageView.setImageBitmap(myBitmap);
}

Todas las respuestas están desactualizadas. Es mejor usar picasso para tales fines. Tiene muchas características, incluido el procesamiento de imágenes de fondo.

¿Mencioné que es súper fácil de usar:

Picasso.with(context).load(new File(...)).into(imageView);

Desde el sitio oficial: http://developer.android.com/training/displaying-bitmaps/load-bitmap.html

ImageView image = (ImageView) findViewById(R.id.imagePreview);           
try {
    image.setImageBitmap(decodeSampledBitmap(picFilename));
} catch (Exception e) {
    e.printStackTrace();
}

Aquí los métodos:

    private int calculateInSampleSize(
            BitmapFactory.Options options, int reqWidth, int reqHeight) {
        // Raw height and width of image
        final int height = options.outHeight;
        final int width = options.outWidth;
        int inSampleSize = 1;

        if (height > reqHeight || width > reqWidth) {

            final int halfHeight = height / 2;
            final int halfWidth = width / 2;

            // Calculate the largest inSampleSize value that is a power of 2 and keeps both
            // height and width larger than the requested height and width.
            while ((halfHeight / inSampleSize) > reqHeight
                    && (halfWidth / inSampleSize) > reqWidth) {
                inSampleSize *= 2;
            }
        }

        return inSampleSize;
    }

    private Bitmap decodeSampledBitmap(String pathName,
            int reqWidth, int reqHeight) {

        // First decode with inJustDecodeBounds=true to check dimensions
        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(pathName, options);

        // Calculate inSampleSize
        options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

        // Decode bitmap with inSampleSize set
        options.inJustDecodeBounds = false;
        return BitmapFactory.decodeFile(pathName, options);
    }

//I added this to have a good approximation of the screen size: 
    private Bitmap decodeSampledBitmap(String pathName) {
        Display display = getWindowManager().getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        int width = size.x;
        int height = size.y;
        return decodeSampledBitmap(pathName, width, height);
    }   

Puedes usar:

ImageView imgView = new ImageView(this);
InputStream is = getClass().getResourceAsStream("/drawable/" + fileName);
imgView.setImageDrawable(Drawable.createFromStream(is, ""));

       public static Bitmap decodeFile(String path) {
    Bitmap b = null;
    File f = new File(path);
    // Decode image size
    BitmapFactory.Options o = new BitmapFactory.Options();
    o.inJustDecodeBounds = true;

    FileInputStream fis = null;
    try {
        fis = new FileInputStream(f);
        BitmapFactory.decodeStream(fis, null, o);
        fis.close();

        int IMAGE_MAX_SIZE = 1024; // maximum dimension limit
        int scale = 1;
        if (o.outHeight > IMAGE_MAX_SIZE || o.outWidth > IMAGE_MAX_SIZE) {
            scale = (int) Math.pow(2, (int) Math.round(Math.log(IMAGE_MAX_SIZE / (double) Math.max(o.outHeight, o.outWidth)) / Math.log(0.5)));
        }

        // Decode with inSampleSize
        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;

        fis = new FileInputStream(f);
        b = BitmapFactory.decodeStream(fis, null, o2);
        fis.close();

    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return b;
}

public static Bitmap showBitmapFromFile(String file_path)
{
    try {
        File imgFile = new  File(file_path);
        if(imgFile.exists()){

            Bitmap pic_Bitmap = decodeFile(file_path);
            return pic_Bitmap;

        }
    } catch (Exception e) {
        MyLog.e("Exception showBitmapFromFile");
        return null;
    }
    return null;
}   

Si está utilizando la carga de imágenes en la Vista de lista, utilice el concepto Acuario.

https://github.com/AshishPsaini/AqueryExample

     AQuery  aq= new AQuery((Activity) activity, convertView);
            //load image from file, down sample to target width of 250 pixels .gi 
    File file=new File("//pic/path/here/aaaa.jpg");
    if(aq!=null)
    aq.id(holder.pic_imageview).image(file, 250);

Cómo mostrar imágenes desde la ruta de la carpeta en Android

Primero: asegúrese de agregar permisos al archivo Mainfest:

 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

##: Hacer una clase MyGallery

public class MyGallery extends Activity {

Ahora crea su clase Xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_marginLeft="12dp"
        android:background="@drawable/ic_arrow_back_black_24dp" />
</RelativeLayout>


<com.google.android.gms.ads.AdView
    android:id="@+id/adView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_gravity="center|bottom"
    android:visibility="gone"
    ads:adSize="BANNER"

    android:horizontalSpacing="5dp"
    android:numColumns="2"
    android:smoothScrollbar="true"
    android:verticalSpacing="5dp"></GridView>

Hacer también el adaptador galleryadapter.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:id="@+id/galleryLayout"
android:padding="2dp">

Agregue su propia clase Drawable to Selector y créela res> drawable> selector_shareimage.xml

<?xml version="1.0" encoding="utf-8"?>

<item android:drawable="@drawable/result_bt_mail" android:state_enabled="true" android:state_pressed="true"/>
<item android:drawable="@drawable/result_bt_mail" android:state_enabled="true" android:state_focused="true"/>
<item android:drawable="@drawable/result_bt_mail" android:state_enabled="true" android:state_selected="true"/>
<item android:drawable="@drawable/result_bt_mail_s"/>

Puede usar esto para acceder a una carpeta específica y obtener una imagen particular

 public void Retrieve(String path, String Name)
   {
    File imageFile = new File(path+Name);

    if(imageFile.exists()){

        Bitmap myBitmap = BitmapFactory.decodeFile(path+Name);
        myImage = (ImageView) findViewById(R.id.savedImage);
        myImage.setImageBitmap(myBitmap);
        Toast.makeText(SaveImage.this, myBitmap.toString(), Toast.LENGTH_LONG).show();

    }
}

Y luego puedes llamarlo por

Retrieve(Environment.getExternalStorageDirectory().toString()+"/Aqeel/Images/","Image2.PNG");
Toast.makeText(SaveImage.this, "Saved", Toast.LENGTH_LONG).show();
