标签： android

以下是我的imageview。我在listview中使用它但是应用程序在启动时崩溃。当我将布局宽度和高度设置为wrap_content时它正在工作但是大图像显示为属性是wrap_content。请帮忙

<ImageView
        android:layout_width="50dp"
        android:layout_height="50dp"

        android:id="@+id/imgView"/>

以下是logcat：

你有一个内存不足的例外，我不知道确切的值，但是当你将位图加载到内存中时，由于加载大而需要像 width * height * 3 MB 这样的空间内存中的位图如此应用耗尽内存并崩溃，您可能认为减小ImageView的大小可能会解决此问题。 但是没有！这只是视图的大小而不是位图。您要做的是以某种方式缩放图像，然后将其加载到ImageView或使用像 RecycleView 在您的应用中

使用以下代码段来压缩图片，来源：Bayoz Swipe Menu 

public static Bitmap decodeSampledBitmapFromFile(String path,
                                                     int reqWidth, int reqHeight) {

        // First decode with inJustDecodeBounds=true to check dimensions
        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(path, options);

        // Calculate inSampleSize
        options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

        // Decode bitmap with inSampleSize set
        options.inJustDecodeBounds = false;
        return BitmapFactory.decodeFile(path, options);
    }

计算样本量：

 public static 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;
    }

在您的情况下，如果您要将文件 image1.jpg 加载到 50x50 的ImageView，请调用此函数

Bitmap b=decodeSampledBitmapFromFile(path,50,50)

并将其设置为imageView，如：

ImageView.setImageBitmap(b);

如果您使用原始图像 检查用于在此ImageView中设置的图像的高度和宽度是否太大。如果它的大小很大，请使用小尺寸的图像。 如果在小ImageViews上设置大图像，则会导致默认错误。
