I want to show a spinning refresh when the data is loading but getting this exception. I am using async task for my processing. Please guide how to properly add progress dialog to give the spinning effect. ANy help will be appreciated.
My widget provider class-onUpdate() method
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
//---
mProgressDialog = new ProgressDialog(context);
mProgressDialog.setIndeterminate(false);
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
try {
fetchTask.execute().get();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mContext = context;
}
protected void onPreExecute(){
mProgressDialog.show();
//updateViews.setViewVisibility(R.id.refresh, View.GONE);
//updateViews.setViewVisibility(R.id.progress, View.VISIBLE);
}
protected Store doInBackground(URL... arg0) {
//my stuff
}
protected void onPostExecute(Store storeObj) {
mProgressDialog.dismiss();
//updateViews.setViewVisibility(R.id.progress, View.GONE);
//updateViews.setViewVisibility(R.id.refresh, View.VISIBLE);
pushWidgetUpdate(mContext,updateViews);
}
My xml
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent">
<ImageButton
android:id="#+id/refresh"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
android:layout_marginLeft="25dp"
android:layout_marginRight="20dp"
android:background="#0079C1"
android:src="#drawable/navigation_refresh"
android:visibility="visible" />
<ProgressBar
android:id="#+id/progress"
android:indeterminate="true"
style="?android:attr/progressBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:visibility="gone" />
</RelativeLayout>

Got it corrected. I had incorrect width, height for button and progress bar, corrected that. Also, made foll. changes to code..Here is the correct one. Nothing to be done in onUpdate.
protected void onPreExecute(){
updateViews.setViewVisibility(R.id.refresh, View.GONE);
updateViews.setViewVisibility(R.id.progress, View.VISIBLE);
pushWidgetUpdate(mContext,updateViews);
}
protected void onPostExecute(Store storeObj) {
//my stuff
updateViews.setViewVisibility(R.id.progress, View.GONE);
updateViews.setViewVisibility(R.id.refresh, View.VISIBLE);
pushWidgetUpdate(mContext,updateViews);
}
//My Layout file
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent">
<ImageButton
android:id="#+id/refresh"
android:layout_width="70dp"
android:layout_height="80dp"
android:layout_marginLeft="25dp"
android:layout_marginRight="20dp"
android:background="#0079C1"
android:src="#drawable/navigation_refresh"
android:visibility="visible" />
<ProgressBar
android:id="#+id/progress"
android:indeterminate="true"
style="?android:attr/progressBarStyle"
android:layout_width="70dp"
android:layout_height="80dp"
android:layout_margin="10dp"
android:indeterminateBehavior="cycle"
android:visibility="gone" />
</RelativeLayout>
