android - 如何在 ImageView 中设置大图像

Question

我有一个 ImageView ，我想在上面设置图像。图像的大小为 7,707,446 字节。每当我尝试设置布局时，应用程序都会崩溃，错误是内存不足错误。任何人都可以建议我如何解决它。xml 是:-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<ScrollView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:scrollbars="none">

    <RelativeLayout

        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/image" >
    </RelativeLayout>
</ScrollView>

Bitmap picture=BitmapFactory.decodeFile("/sdcard...");
    int width = picture.getWidth();
    int height = picture.getWidth();
    float aspectRatio = (float) width / (float) height;
    int newWidth = 70;
    int newHeight = (int) (70 / aspectRatio);       
    picture= Bitmap.createScaledBitmap(picture, newWidth, newHeight, true);


public static Bitmap decodeImage(String arrayList_image) {

        URL aURL;

        try {

            aURL = new URL(arrayList_image);

            URLConnection conn = aURL.openConnection();

            conn.connect();

            InputStream is = conn.getInputStream();

            BufferedInputStream bis = new BufferedInputStream(is);

            bm = BitmapFactory.decodeStream(bis);

            bis.close();

            is.close();

            return bm;

        } catch (MalformedURLException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();
        }
        return null;
    }
