Android: . lang。OutOfMemoryError:未能分配23970828字节分配，2097152空闲字节和2MB直到OOM

我想显示的位图图像在ImageView从sd卡已经存储。运行后，我的应用程序是崩溃和得到OutOfMemoryError错误:

(. lang。OutOfMemoryError:未能分配23970828字节分配，2097152空闲字节和2MB直到OOM)

我不知道为什么它没有记忆。我觉得我的图片太大了，所以我试着改变它。

Iterator<String> it = imageArray.iterator();
while (it.hasNext()) {
  Object element = it.next();
  String objElement = element.toString();
  Log.e("objElement ", " = " + objElement);
  final ImageView imageView = new ImageView (getContext());
  final ProgressBar pBar = new ProgressBar(getContext(), null, 
                                           android.R.attr.progressBarStyleSmall);
  imageView.setTag(it);
  pBar.setTag(it);

  imageView.setImageResource(R.drawable.img_placeholder);
  pBar.setVisibility(View.VISIBLE);

  if (objElement.endsWith(mp3_Pattern)) {
     Log.e("Mp3 ", " ends with ");
     pBar.setVisibility(View.GONE);
     imageView.setImageResource(R.drawable.audio_control);
  }
  if (objElement.endsWith(png_Pattern)) {
     Bitmap bitmap = BitmapFactory.decodeFile(objElement);
     int size = Math.min(bitmap.getWidth(), bitmap.getHeight());
     int x = (bitmap.getWidth() - size) / 2;
     int y = (bitmap.getHeight() - size) / 2;
     Bitmap bitmap_Resul = Bitmap.createBitmap(bitmap, x, y, size, size);
     Log.e("bitmap_Resul "," = "+ bitmap_Resul);

     if (bitmap_Resul != bitmap) {
        bitmap.recycle();
     }
     imageView.setImageBitmap(bitmap_Resul);
     Log.e("png_Pattern ", " ends with ");
     Log.e(" bitmap "," = " + bitmap);
  }

  holder.linearLayout.addView(imageView);
  holder.linearLayout.addView(pBar);

当前回答

stream = activity.getContentResolver().openInputStream(uri);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.RGB_565;

bitmap = BitmapFactory.decodeStream(stream, null, options);
int Height = bitmap.getHeight();
int Width = bitmap.getWidth();
enter code here
int newHeight = 1000;
float scaleFactor = ((float) newHeight) / Height;
float newWidth = Width * scaleFactor;

float scaleWidth = scaleFactor;
float scaleHeight = scaleFactor;
Matrix matrix = new Matrix();
matrix.postScale(scaleWidth, scaleHeight);
resizedBitmap= Bitmap.createBitmap(bitmap, 0, 0,Width, Height, matrix, true);
bitmap.recycle();

然后在Appliaction标签中添加largeheapsize="true

其他回答

我真的不建议像这样编辑清单

android:hardwareAccelerated=“错误”，android:largeHeap=“真实”

这些选项会导致应用程序的动画效果不流畅。此外，“liveData”或更改本地DB(Sqlite, Room)激活缓慢。这不利于用户体验。

所以我推荐RESIZE位图

下面是示例代码

fun resizeBitmap(source: Bitmap): Bitmap {
      val maxResolution = 1000    //edit 'maxResolution' to fit your need
      val width = source.width
      val height = source.height
      var newWidth = width
      var newHeight = height
      val rate: Float

            if (width > height) {
                if (maxResolution < width) {
                    rate = maxResolution / width.toFloat()
                    newHeight = (height * rate).toInt()
                    newWidth = maxResolution
                }
            } else {
                if (maxResolution < height) {
                    rate = maxResolution / height.toFloat()
                    newWidth = (width * rate).toInt()
                    newHeight = maxResolution
                }
            }
            return Bitmap.createScaledBitmap(source, newWidth, newHeight, true)
 }

实际上，你可以在你的清单中添加这些行android:hardwareAccelerated="false"， android:largeHeap="true"，这是在某些情况下工作，但要注意，代码的另一部分可能与此争论。

<application
    android:allowBackup="true"
    android:hardwareAccelerated="false"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

我是一个机器人开发的新手，但我希望我的解决方案有帮助，它在我的条件下完美工作。我使用Imageview并将其背景设置为“src”，因为我试图制作一帧动画。我得到了同样的错误，但当我试图编码这个它工作

int ImageID = this.Resources.GetIdentifier(questionPlay[index].Image.ToLower(), "anim", PackageName);
            imgView.SetImageResource(ImageID);
            AnimationDrawable animation = (AnimationDrawable)imgView.Drawable;
            animation.Start();
            animation.Dispose();

我也有这个问题。

和上面大多数人一样。这个问题是由巨大的形象造成的。

只是调整一些图像的大小，而且不需要更改任何代码。

2017-03-09 02:26:06

Bitmap image =((BitmapDrawable)imageView1.getDrawable()).getBitmap();

ByteArrayOutputStream byteArrayOutputStream=new ByteArrayOutputStream();

image.compress(Bitmap.CompressFormat.JPEG,50/100,byteArrayOutputStream);

50/100如果使用100，那么原始分辨率可以停止应用程序的内存不足。

如果50或小于100，这将是50%或小于100的分辨率，这样可以防止内存不足的问题
