Показати перегляд зображення з контуру файлу?

Мені потрібно показати зображення, використовуючи лише ім'я файлу, а не ідентифікатор ресурсу.

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

Я маю зображення img1 у папці, що малюється. Я хочу показати це зображення з файлу.

Як я можу це зробити?

Labeeb має рацію щодо того, чому вам потрібно встановити зображення за допомогою шляху, якщо ваші ресурси вже лежать у папці ресурсів,

Такий шлях потрібен лише тоді, коли ваші зображення зберігаються на SD-карті.

І спробуйте наведений нижче код, щоб встановити зображення Bitmap з файлу, що зберігається на SD-карті.

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);

}

І включіть цей дозвіл у файл маніфесту:

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

Я думаю, ти можеш цим скористатися

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

Ви також можете використовувати:

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

    }

Це робить декодування растрових зображень для вас неявним.

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);
}

Усі відповіді застаріли. Найкраще використовувати для таких цілей пікассо . Він має безліч функцій, включаючи обробку фонових зображень.

Я згадав, що це дуже просто у використанні:

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

З офіційного сайту: 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();
}

Ось методи:

    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);
    }   

Ви можете використовувати:

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;
}   

якщо ви використовуєте завантаження зображень у перегляді списку, тоді використовуйте концепцію Aquery.

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);

Як показувати зображення із шляху папки в Android

Перше: переконайтеся, що у вас є права доступу до файлу Mainfest:

Ви можете використовувати це для доступу до певної папки та отримання конкретного зображення

 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();

    }
}

І тоді ви можете зателефонувати

Toast.makeText(SaveImage.this, "Saved", Toast.LENGTH_LONG).show();
