Question

活动即时通讯＆＃34;重新创建（）＆＃34;在它的xml布局中包含一个surfaceview，看起来我很难从surfaceview使用的bitmapfactory释放内存。

每次重新创建时，每个解码10个位图，大约5-10KB。

我尝试将所有位图设置为null并在每次娱乐之前运行system.gc，但这并没有帮助。

我只是想定期重新创建我的表面视图，但我找不到比重新创建它更好的方法。

是否有一种更有效的方法来重新初始化我的表面视图，如果没有，你能告诉我这个logcat的垃圾收集是怎么回事吗？

查看位图recycle（）函数。您可能还需要将位图选项设置为可清除。这是一个片段，我在其中调整位图大小并输出为JPEG：

BitmapFactory.Options options = new BitmapFactory.Options();;
options.inPurgeable = true;

Bitmap original = BitmapFactory.decodeByteArray(input , 0, input.length, options);
Bitmap resized = Bitmap.createScaledBitmap(original, NEW_WIDTH, NEW_HEIGHT, true);

ByteArrayOutputStream blob = new ByteArrayOutputStream();
resized.compress(Bitmap.CompressFormat.JPEG, 30, blob);

// recycle the memory
original.recycle();
resized.recycle();

释放内存的麻烦。重新创建一个活动〜30次后我的内存不足
