How to boost to load multiple images from web to ImageViews

To load several images from a website, the following code was written.

    public void connectImgtoView(final int max) {

        new Thread(new Runnable() {
            @Override
            public void run() {
                URL url = null;
                for (int i = 0; i < max; i++) {
                    try {
                        url = new URL(postImgUrl.get(i));
                    } catch (MalformedURLException e) {
                        e.printStackTrace();
                    }

                    try {
                        final BufferedInputStream bufferedInputStream
                                = new BufferedInputStream(url.openStream());
                        Bitmap bitmap = BitmapFactory.decodeStream(bufferedInputStream);
                        bufferedInputStream.close();

                        final Bitmap scaledBitmap = Bitmap.createScaledBitmap(
                                bitmap,
                                (int) (992),
                                (int) (1403),
                                true
                        );

                        final int finalI = i;
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                postImg[finalI].setImageBitmap(scaledBitmap);
                            }
                        });
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
                progressOFF();
            }
        }).start();
    }

Although this method is performed successfully, there is a problem that the performance speed is too slow.

So I want to know what is faster than this method.

Please help me.

Variable description

postImgUrl : type is ArrayList, this is url that has image i want

postImg : type is ImageView Array, this is ImageView that exists in the layout.

Try placing the for loop out side of Thread so that you can instantiate and work multiple Threads simultaneously.

public void connectImgtoView(final int max) {
    for (int i = 0; i < max; i++) {
        new Thread(new Runnable() {
            @Override
            public void run() {
                URL url = null;
                    try {
                        url = new URL(postImgUrl.get(i));
                    } catch (MalformedURLException e) {
                        e.printStackTrace();
                    }

                    try {
                        final BufferedInputStream bufferedInputStream
                                = new BufferedInputStream(url.openStream());
                        Bitmap bitmap = BitmapFactory.decodeStream(bufferedInputStream);
                        bufferedInputStream.close();

                        final Bitmap scaledBitmap = Bitmap.createScaledBitmap(
                                bitmap,
                                (int) (992),
                                (int) (1403),
                                true
                        );

                        final int finalI = i;
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                postImg[finalI].setImageBitmap(scaledBitmap);
                            }
                        });
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                progressOFF();
            }
        }).start();
    }
}
