android - Android应用程序中的OutOfMemoryError

Question

我之前曾就我的 Android 应用程序中的 OutOfMemoryError 问题寻求帮助。由于我还没有解决方案，所以我需要再次请你给我一个解决方案。我在几个真实的 android 设备上测试了我的应用程序。但是在 Samsung Galaxy S3 android 4.0.4 中我有 OutOfMemoryError 问题。 Logcat 消息如下。谢谢。

使用下面的方法来缩小图像的大小。由于图像尺寸过大，您收到 OutOfMemory 错误。

public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId,
        int reqWidth, int reqHeight) {

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

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

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    return BitmapFactory.decodeResource(res, resId, options);
}

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) {
        if (width > height) {
            inSampleSize = Math.round((float)height / (float)reqHeight);
        } else {
            inSampleSize = Math.round((float)width / (float)reqWidth);
        }
    }
    return inSampleSize;
}

并在您的代码中使用

mImageView.setImageBitmap(
    decodeSampledBitmapFromResource(getResources(), R.id.myimage, 100, 100));
