如何顯示進度定製對話的對話？

Question

我從服務器獲取圖像，並顯示在定製對話框它，我想顯示進度對話框，同時圖像的獲取。

我用這

loadingDialog = ProgressDialog.show(getActivity(), "", "Loading. Please wait...", true); 

但定製對話框下隱藏。

Answer 1

將這個代碼在添加下面的代碼之後，從服務器獲取的圖像

try { 
    progDialog = new ProgressDialog(Activity_FindInfo.this); 
    progDialog.setIndeterminate(true); 
    progDialog.setMessage("loading"); 
    progDialog.setCancelable(false); 
    progDialog.show(); 
} catch (Exception ex) { 
} 

Answer 2

聲明這在你的類

private ProgressDialog progDialog; 

呼叫只是調用之前你抓取圖像..

try { 
    progDialog = new ProgressDialog(yourCustomDialog.getContext()); 
    progDialog.setIndeterminate(true); 
    progDialog.setMessage("fetching image..."); 
    progDialog.setCancelable(false); 
    progDialog.show(); 
} catch (Exception ex) { 
} 

然後當圖像被提取之前添加此駁回對話框..

try { 
    if (progDialog != null && progDialog.isShowing()) { 
     progDialog.dismiss(); 
    } 
} catch (Exception ex) { 
}
