Android: stopping the thread while using Alert Dialog

I have a program which first detects whether SD-card is present or not, if sd-card is not present, an alert dialog is presented which asks the user to retry or to exit. In short, sd-card is a must. However, in the case where there is no sd-card, the application continues working on the thread or the t开发者_运维问答hread continues even after going the alert dialog part of my application. in short, what I want is that my application should wait for the alertdialog and get the input from the user.

Can anyone help me here.. thanks

I dont completely understand your problem, I think following code will help you a little bit. It waits till OK clicked

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Please try again.").setPositiveButton("OK", dialogClickListener).show();
DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        switch (which){
        case DialogInterface.BUTTON_POSITIVE:
            //OK  button clicked,  Add your code here

            break;


        }
    }
};

Edited: If you call alertBox from thread it will not work. You should call alertDialog from a UI thread
runOnUiThread(new Runnable() { @Override public void run() { } });
