我正在使用位图.当代码运行时,它显示内存不足错误.如何避免错误.我的代码如下.提前致谢.

Bitmap myBitmap = Image.decodeSampledBitmapFromUri(path, 250, 500); 
img_cook[index].setImageBitmap(myBitmap); 

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

    Bitmap bm = null;

    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(path, options);
    options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
    options.inJustDecodeBounds = false;
    bm = BitmapFactory.decodeFile(path, options);

    return bm;
}

public static int calculateInSampleSize(BitmapFactory.Options options,
        int reqWidth, int reqHeight) {
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) …

                videoShowed.setVisibility(View.VISIBLE);
                mVideoView.setBackgroundColor(Color.BLACK);
                bar.show();
                int newVideoId = button1.getId();
                Constant.database.getContentValues(newVideoId);

                Log.d("video", getVideo);
                mVideoView.setSoundEffectsEnabled(true);
                mVideoView.setDrawingCacheEnabled(true);
                mediaController.setAnchorView(mVideoView);
                mVideoView.setVideoURI(Uri.parse(getVideo));
                mVideoView.setKeepScreenOn(true);
                mVideoView.setMediaController(mediaController);
                mVideoView.requestFocus();
                mVideoView.setOnPreparedListener(PreparedListener);
                Constant.database.close();

            } catch (Exception e) {
                Log.e(TAG, "error: " + e.getMessage(), e);
                bar.dismiss();
            }
        }
    };
}

我附上了我的代码.
