OutofMemoryError:位图大小超出 VM 预算 (Android) [英] OutofMemoryError: bitmap size exceeds VM budget (Android)

问题描述

在 BitmapFactory 中出现异常.不知道是什么问题.(嗯，我能猜到问题所在，但不知道为什么会发生)

Getting an Exception in the BitmapFactory. Not sure what is the issue. (Well I can guess the issue, but not sure why its happening)

ERROR/AndroidRuntime(7906): java.lang.OutOfMemoryError: bitmap size exceeds VM budget

ERROR/AndroidRuntime(7906):     at android.graphics.BitmapFactory.decodeFile(BitmapFactory.java:295)

我的代码非常简单.我定义了一个带有默认图像的 XML 布局.我尝试在 SDCard 上加载 bm(如果存在 - 它是).如果不是，则显示默认图像.无论如何..这是代码:

My code is pretty straight forward. I defined an XML layout w/ a default image. I try to load a bm on the SDCard (if present - it is). If not it shows the default image. Anyway.. Here is code :

public class showpicture extends Activity {
  public void onCreate(Bundle savedInstanceState) {

         /** Remove menu/status bar **/
         requestWindowFeature(Window.FEATURE_NO_TITLE);
         final Window win = getWindow();   
         win.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

            Bitmap bm;
         super.onCreate(savedInstanceState);
         setContentView(R.layout.showpicture);
            try {
         ImageView mImageButton = (ImageView)findViewById(R.id.displayPicture);
         bm = Bitmap.createScaledBitmap(BitmapFactory.decodeFile("/sdcard/dcim/Camera/20091018203339743.jpg"),100, 100, true);
         parkImageButton.setImageBitmap(bm);
         }
         catch (IllegalArgumentException ex) {
          Log.d("MYAPP",ex.getMessage());
         } 
            catch (IllegalStateException ex) {

它在 bm=Bitmap.createScaledBitmap 上失败了有什么想法吗?我在论坛上做了一些研究，它指向这篇文章我只是不知道为什么它不起作用.任何帮助都会很棒！谢谢，

It fails on the bm=Bitmap.createScaledBitmap any thoughts? I did some research on the forums, and it pointed to this post I just don't know why it is not working. Any help would be great! Thanks,

克里斯.
