Show Image View from file path?

问题:

I need to show an image by using the file name only, not from the resource id.

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

I have the image img1 in the drawable folder. I wish to show that image from the file.

How can I do this?

回答1:

Labeeb is right about why you need to set image using path if your resources are already laying inside the resource folder ,

This kind of path is needed only when your images are stored in SD-Card .

And try the below code to set Bitmap images from a file stored inside a SD-Card .

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);

}

And include this permission in the manifest file:

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

回答2:

I think you can use this

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

回答3:

You can also use:

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

    }

This does the bitmap decoding implicit for you.

回答4:

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);
}

回答5:

All the answers are outdated. It is best to use picasso for such purposes. It has a lot of features including background image processing.

Did I mention it is super easy to use:

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

回答6:

From the official site: 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();
}

Here the methods:

    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);
    }   

回答7:

You can use:

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

回答8:

You may use this to access a specific folder and get particular image

 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();

    }
}

And then you can call it by

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

回答9:

       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;
}   

if you are using image loading in List view then use Aquery concept .

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);

        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\"
    ads:adUnitId=\"@string/banner_id\" />

<GridView
    android:id=\"@+id/gridView\"
    android:layout_width=\"wrap_content\"

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

Also Make Adapter 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\">

Add your own Drawable to Selector class,and create it 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\"/>
