我在显示自定义进度对话框时遇到错误。我用40个不同的图像创建了进度对话框。它很好。但如果我尝试显示超过8-10次应用程序崩溃的对话框。带自定义进度对话框的应用程序崩溃

我也做了一些内存管理规定如下：

public void unbindDrawables(View view) { 
     if (view.getBackground() != null) { 
      view.getBackground().setCallback(null); 
     } 
     if (view instanceof ViewGroup) { 
      for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) { 
       unbindDrawables(((ViewGroup) view).getChildAt(i)); 
      } 
      try{ 
       ((ViewGroup) view).removeAllViews(); 
      }catch (UnsupportedOperationException e) {} 
     } 
    }

什么我失踪？

进度条的xml：

<RelativeLayout android:layout_width="fill_parent" 
android:layout_marginLeft="40dp" 
android:layout_height="wrap_content" 
android:layout_centerInParent="true" 
android:background="@drawable/progress_context"> 
<ProgressBar android:layout_height="100dp" 
      android:layout_width="100dp" 
      android:id="@+id/prg" 
      android:layout_centerHorizontal="true" 
      android:layout_marginTop="10dp" 
      android:drawingCacheQuality="low" 
      style="@android:style/Widget.ProgressBar.Large.Inverse" 
      android:indeterminateDrawable="@drawable/custom_progress_drawable"/> 

<TextView android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/prg" 
    android:layout_marginTop="15dp" 
    android:textSize="20sp" 
    android:textColor="#ffffff" 
    android:text="@string/loading" 
    android:paddingBottom="10dp" 
    android:id="@+id/txtProgressMessage" 
    android:layout_centerHorizontal="true"/> 
</RelativeLayout>

你能提供自定义进度对话框代码？ –

“我缺少什么？”一些代码... – RvdK

我得到了它..

我的代码：

public class CustomProgressDialog extends ProgressDialog{ 
    private ImageView imageView; 
    public CustomProgressDialog(Context context) {  
     super(context); 
    } 

@Override 
    public void onWindowFocusChanged(boolean hasFocus){ 
     imageView = (ImageView) findViewById(R.id.loadingImageView); 
     AnimationDrawable myAnimation = (AnimationDrawable) imageView.getBackground(); 
     myAnimation.start(); 
    } 

    public static CustomProgressDialog createDialog(Context context,String title,String message){ 
     CustomProgressDialog dialog=null; 
     if(title.length()==0||title==null) 
      dialog=new CustomProgressDialog(context); 
     else{ 
      dialog=new CustomProgressDialog(context); 
      dialog.setTitle(title); 
     } 
     dialog.getWindow().getAttributes().gravity=Gravity.CENTER; 
     return dialog; 
    } 

public void setImageCallBack(){ 
    if(imageView != null) 
     imageView.getBackground().setCallback(null); 
}

}

从哪里我们将得到loadingImageView –

你的应用程序崩溃，因为你的JVM的内存不足而无法创建/加载另一个位图。可能的解决方案是：

利用已经创建的，而不是用来使用例如“回收（）”方法，位图对象有关在Android的位图工作阅读：http://developer.android.com/reference/android/graphics/Bitmap.html
压缩位图，不创建它们的大量数据并重新使用已创建的位图，而不是创建新的位图。

P.S.如果你提供了更多的代码，你可以为你的问题获得代码解决方案。
