Bildansicht vom Dateipfad anzeigen?

Ich muss ein Bild nur mit dem Dateinamen anzeigen, nicht mit der Ressourcen-ID.

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

Ich habe das Bild img1 im Zeichenordner. Ich möchte das Bild aus der Datei zeigen.

Wie kann ich das machen?

Labeeb hat Recht, warum Sie das Image mithilfe des Pfads festlegen müssen, wenn sich Ihre Ressourcen bereits im Ressourcenordner befinden.

Diese Art von Pfad wird nur benötigt, wenn Ihre Bilder auf einer SD-Karte gespeichert sind.

Und versucht , die folgenden Code - Set Bitmap - Bilder aus einer Datei innerhalb einer SD-Karte gespeichert.

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);

}

Und fügen Sie diese Berechtigung in die Manifestdatei ein:

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

Ich denke, Sie können dies verwenden

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

Sie können auch verwenden:

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

    }

Dies führt die für Sie implizite Bitmap-Dekodierung durch.

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);
}

Alle Antworten sind veraltet. Es ist am besten, Picasso für solche Zwecke zu verwenden. Es hat viele Funktionen, einschließlich Hintergrundbildverarbeitung.

Habe ich schon erwähnt, dass es super einfach zu bedienen ist:

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

Von der offiziellen Website: 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();
}

Hier die Methoden:

    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);
    }   

Sie können verwenden:

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;
}   

Wenn Sie das Laden von Bildern in der Listenansicht verwenden, verwenden Sie das Aquery-Konzept.

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);

So zeigen Sie Bilder aus dem Ordnerpfad in Android an

Ganz zuerst: Stellen Sie sicher, dass Sie Berechtigungen zur Mainfest-Datei hinzugefügt haben:

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

##: Erstelle eine Klasse MyGallery

            photo = newItemList;
            notifyDataSetChanged();

}

Erstellen Sie nun die XML-Klasse

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:orientation="vertical">

    android:layout_height="56dp"
    android:background="@color/colorPrimary"
    android:minHeight="?attr/actionBarSize">

    <TextView
        android:id="@+id/gallerytxt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:layout_gravity="center"
        android:fontFamily="@string/font_fontFamily_medium"
        android:text="My Gallery"

        android:textColor="@android:color/black"
        android:textStyle="bold" />

    <ImageButton
        android:id="@+id/btn_back"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_centerVertical="true"
        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:horizontalSpacing="5dp"
    android:numColumns="2"
    android:smoothScrollbar="true"
    android:verticalSpacing="5dp"></GridView>

Machen Sie auch 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">

Um das Bild im Detail zu sehen, erstellen Sie eine neue Klasse ImageDetail:

Fügen Sie Ihre eigene Drawable zur Selector-Klasse hinzu und erstellen Sie sie 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"/>

Sie können dies verwenden, um auf einen bestimmten Ordner zuzugreifen und ein bestimmtes Bild abzurufen

 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();

    }
}

Und dann können Sie es anrufen

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