Android進度條不排除

Question

我正在使用進度對話框顯示加載網頁時的進度，但有時無法正常工作。進程對話框在加載頁面時不會被解除。

我加入了進度條這樣

public boolean shouldOverrideUrlLoading(WebView view, String url) { 
    //Added progress dialog 
} 

public void onPageFinished(WebView view, String url) { 
    if(progressdialog.isShowing()) 
     progressdialog.dismiss(); //Dismissed the progress, but sometimes never dismiss it 
} 

Answer 1

android_dev，使用處理

public void onPageFinished(WebView view, String url) 
    { 
    handler.sendEmptyMessage(0); 
    } 

    Handler handler = new Handler() { 
     @Override 
     public void handleMessage(Message msg) { 
    if(progressdialog.isShowing() || progressdialog!=null) 
    progressdialog.dismiss(); 
    progressdialog=null; 
     } 
    } 

&你做！
