Android Webview loading dialog not being dismissed
I am using the following code
class CustomWebViewClient extends WebViewClient {
Context context;
ProgressDialog pd = null;
public CustomWebViewClient (Context c){
context = c;
}
public void onPageFinished(WebView view, String url){
pd.dismiss();
}
public boolean shouldOverrideUrlLoading(final WebView view, final String url) {
pd = ProgressDialog.show(context, "", "pageload. Please wait...", true);
view.loadUrl(url);
return true;
}
}
When I click a link in the WebView, the dialog appears and the page begins to load, however when the page is finished loading, the dialog is still on the screen. Obviously the code is simple enough, but I cant figure this out. Also, I guess I should add that the links being clicked have a few redirects, but I am not sure if that is rel开发者_如何学Cated to the cause here.
How can I do this right?
Steven & Sander, try dismissing the progress dialog in a Handler
Something like this:
class pdHandler extends Handler {
@Override
public void handleMessage(Message msg) {
if(pd != null)
{
pd.dismiss();
pd = null;
}
}
Then call your handler in onPageFinished:
public void onPageFinshed(WebView view, String url){
pdHandler.sendEmptyMessage(0);
}
& you are done!
You missed @Override
annotation.
Here is right code:
class CustomWebViewClient extends WebViewClient {
Context context;
ProgressDialog pd = null;
public CustomWebViewClient(Context c){
context = c;
}
@Override
public void onPageFinished(WebView view, String url){
if (pd != null && pd.isShowing())
{
pd.dismiss();
}
}
@Override
public boolean shouldOverrideUrlLoading(final WebView view, final String url) {
pd = ProgressDialog.show(context, "", "pageload. Please wait...", true);
view.loadUrl(url);
return true;
}
}
This code works, but progress dialog does't appears on initial loading. If you need it, add this code to the class' constructor:
pd = ProgressDialog.show(context, "", "pageload. Please wait...", true);
This does work, you spelled Finished wrong, you wrote "onPageFinshed"
