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

问题描述

在BitmapFactory中获取异常。不确定是什么问题。 （我可以猜到这个问题，但不知道为什么会发生这种情况）

 ERROR / AndroidRuntime（7906）：java.lang.OutOfMemoryError：位图大小超过VM预算
 
错误/ AndroidRuntime（7906）：在android.graphics.BitmapFactory.decodeFile（BitmapFactory.java:295）

我的代码很简单。我用默认图像定义了一个XML布局。我试图在SDCard上加载一个bm（​​如果存在的话）。如果没有显示默认图像。这里是代码：

  public class showpicture extends Activity {
 public void onCreate（Bundle savedInstanceState）{
 
 / **删除菜单/状态栏** / 
 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）{
  

在code> bm = Bitmap.createScaledBitmap 任何想法？我在论坛上做了一些研究，并指出这篇文章
我只是不知道为什么它不工作。任何帮助将是伟大的！谢谢，

Chris。

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)

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) {

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,

Chris.
