我在顯示自定義進度對話框時遇到錯誤。我用40個不同的圖像創建了進度對話框。它很好。但如果我嘗試顯示超過8-10次應用程序崩潰的對話框。帶自定義進度對話框的應用程序崩潰

錯誤日誌

我也做了一些內存管理規定如下:

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) {} 
     } 
    } 

什麼我失蹤?

進度條的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>

你能提供自定義進度對話框代碼? –

我得到了它..

我的代碼:

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); 
} 

}

從哪裏我們將得到loadingImageView –

你的應用程序崩潰,因爲你的JVM的內存不足而無法創建/加載另一個位圖。 可能的解決方案是:

  1. 利用已經創建的,而不是用來使用例如「回收()」方法,位圖對象有關在Android的位圖工作閱讀:http://developer.android.com/reference/android/graphics/Bitmap.html

  2. 壓縮位圖,不創建它們的大量數據並重新使用已創建的位圖,而不是創建新的位圖。

P.S.如果你提供了更多的代碼,你可以爲你的問題獲得代碼解決方案。
