How to dismiss a MaterialAlertDialog when a hyperlink is clicked?

Is there a way to dismiss/cancel a MaterialAlertDialog when a hyperlink inside the message was clicked?
Currently the browser is open and when you returned to the app the dialog is still open.
For the buttons there is a listener where you can dismiss/cancel the dialog.
What I want to achieve is to close the dialog when the link is clicked.

add onClickListener to TextView containing hyperlink
use onResume() method to close dialog after you return to it

After reading a bit about setLinkMovementMethod I thought about somethink like:
textView.setLinkMovementMethod(new TextViewLinkHandler() {
// do my stuff ...
// if left blank, nothing will happen on click at the link, so leave it blank to do nothing
})
With the mentioned TextViewLinkHandler()
public abstract class TextViewLinkHandler extends LinkMovementMethod {
// add a method to handle the click
// extract the url and open it
// then dismiss the dialog
}
But maybe this is not the right approach.

how to remove progress dialog while using asynctask in android

i have used asynctask in my programme i have dismiss dialog before intent is passed in postexecute method but in other activity data displays but it still display progress dialog how to remove or what is problem my code is at
http://pastebin.com/bGrMbGCJ

to clear any existing dialog window, use:
dialog.cancel();

You can not have two spinner at a time. Need to use any trick in this case,
Use one common flag set on PostExecute.
Before step#3, on postExecute of both AsyncTask check the flag is already set, if yes just cancel the spinner.
Refer below pseudo code.
postExecute(){
If(taskCompletedFlag == true){
//Code to cancel the spinner.
taskCompletedFlag = false;
}else{
taskCompledtedFlag = true;
}
}
P.S. - In case you are not aware which AsyncTask will initiate first, you can use same mechanism over there.

What is the best way to implement two custom dialogs, one after the other?

through the help of various tutorials, I've managed to write a custom dialog that displays a listview populated by records from a local database. I have set click listeners and figured out how to retrieve the record at the listview item clicked by setting the cursor at the position returned and so on...Now what I want to do is, dismiss this dialog when an item is clicked, and automatically open a new dialog with this cursor's content as the name of the table from which to re-populate the new listview. I'd like to know if anyone knows the best way of doing this in terms of application structure.
Currently, I am calling my dialog to show in my Activity like this:
public void onClick(View view) {
switch(view.getId()) {
case R.id.pickerbutton:
showDialog(DIALOG_PICK_CATEGORY);
break;
}
}
protected Dialog onCreateDialog(int id) {
dialog = null;
switch(id) {
case DIALOG_PICK_CATEGORY:
CustomDialogList.Builder customBuilder = new
CustomDialogList.Builder(SendCookieActivity.this);
customBuilder.setTitle(R.string.category);
dialog = customBuilder.create();
break;
}
return dialog;
}
After this dialog is shown, the user picks a category from the CustomDialogList dialog. I am having a hard time thinking of how to make it so that after the category is picked, this dialog is dismissed (or looks like it's dismissed) and the same one with newly populated items appears (or can be a completely new dialog too). and when someone presses the back button, the previous dialog is shown. Think of it as a file explorer but with only two levels of depth. I'd like to keep using my CustomDialogList because I have customized its look to match everything else in my app. Perhaps what would help me with this problem besides or instead of code, would be some diagrams of how this type of UI flow has been implemented before along with some pseudo code.
Thanks.

Assuming your custom dialog extends Dialog (or one its sub-classes). Have your Activity implement DialogInterface.onDismissListener. Then after you create the dialog with...
dialog = customBuilder.create();
...use dialog.setOnDismissListener(this); before you show it.
Your Activity will have to implement...
#Override
public void onDismiss(DialogInterface dialog) {
// Identify which dialog was dismissed and do something
}

When I have had to do this in the past, I have the onCancel for the dialog open the new dialog.

Forcefully display a empty layout and then fill it with data

I am developing a new app for android 2.2(Froyo), I need to know how to forcefully display a leyout before loading it with dynamic data. I have a LinearLayout with a empty List, wen the appropriate menu is selected I load it with dynamic data which takes some time to load, but wat happens is the screen is empty till the layout is filled with data. I need to display the empty layout which has ly title and show a ProgreesDialog till the list is filled with data. Here is my Activity class.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.deals);
loadDeals();//fills the list with data(URL call)
}

You can user AsyncTask for loading data. During which you will be able to show ProgressDialog as well
http://developer.android.com/reference/android/os/AsyncTask.html

Use AsynchronousTask Class and call loadDeals() from doInBackground Method.Just capture the data on that method.Then work ur UI in postExecute method.It will solve your problem

ProgressDialog in TabHost application ofandroid

I want to use the Progress Dailog in my application. I am facing one issue in doing it, after some RnD I came to know that it is not quite possible to create the progress Dialog I have the Activity Group Class for the TabHost in the application.
I have exactly the same scenario, I have the TabHost in my application and an ActivityGroup Class that has the TabHost Classes. So, when I try to create the Progress Dialog for the Class that is in the Activity Group Class I cannot create it. But if I try to create the Progress Dialog for the Class that is not in the Activity Group I can create it with no issues.
Is there any solutions now?

I think the problem is with context of the progress dialog
Try giving the context of the dialog as getParent()
ProgressDialog.show(getParent(), " Loading...", "Please wait...", true, false);
