Android調用自定義ProgressDialog - 如何？

How to center progress indicator in ProgressDialog easily (when no title/text passed along)Android調用自定義ProgressDialog - 如何？

試圖創建一個自定義progressdialog，但沒有工作..

我的代碼：

public class CustomProgressDialog extends ProgressDialog { 

public CustomProgressDialog(Context context) { 
     super(context, R.style.progress_dialog); 
} 

public static CustomProgressDialog show(Context context, CharSequence title, 
     CharSequence message) { 
    return show(context, title, message, false); 
} 

public static CustomProgressDialog show(Context context, CharSequence title, 
     CharSequence message, boolean indeterminate) { 
    return show(context, title, message, indeterminate, false, null); 
} 

public static CustomProgressDialog show(Context context, CharSequence title, 
     CharSequence message, boolean indeterminate, boolean cancelable) { 
    return show(context, title, message, indeterminate, cancelable, null); 
} 

public static CustomProgressDialog show(Context context, CharSequence title, 
     CharSequence message, boolean indeterminate, 
     boolean cancelable, OnCancelListener cancelListener) { 
    CustomProgressDialog dialog = new CustomProgressDialog(context); 
    dialog.setTitle(title); 
    dialog.setCancelable(cancelable); 
    dialog.setOnCancelListener(cancelListener); 
    dialog.addContentView(new ProgressBar(context), new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); 
    dialog.show(); 

    return dialog; 
} 
}

以及如何ID喜歡稱：

public static CustomProgressDialog dialog; 

public static void showLoaderDialog(String sHead, String sMess) { 
    dialog=new CustomProgressDialog(mycontext).show(mycontext, sHead, sMess, true, true); 
} 
public static void hideLoaderDialog() { 
    dialog.dismiss(); 
}

，但我得到只有崩潰:(爲什麼？怎麼能調用這個自定義對話框？

顯示，請，錯誤日誌。 – 2011-04-05 18:10:09

現在編輯...... – lacas 2011-04-05 18:35:14

在原始文章中，Macarse從'Dialog'擴展了自定義對話框，而不是'ProgressDialog'。也許這就是問題所在？ – bigstones 2011-04-05 19:23:20

也許，你應該叫對話框中這樣說：

public static void showLoaderDialog(String sHead, String sMess) { 
    dialog=new CustomProgressDialog(mycontext); 
    dialog.show(mycontext, sHead, sMess, true, true); 
}

但我可能是錯的。

無論如何，顯示，請稍等代碼行是指CustomProgressDialog.java:37
