Question

i have one problem with handling the thread in android ,in my class i have to create one thread which create some UI after that thread finish i will get some value ,here i want to wait my Main Process until the thread complete it process but when i put wait() or notify in Main process thread does not show the UI in my application

this is sample code

    protected void onCreate(Bundle savedInstanceState) {

         downloadThread = new MyThread(this);
            downloadThread.start();

            synchronized(this){  
                try {
                    this.wait();
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }

 String test=Recognition.gettemp();
    public class MyThread extends Thread {
        private Recognition recognition;

        public MyThread(Recognition recognition) {
            this.recognition = recognition;
            // TODO Auto-generated constructor stub
        }

        @Override
        public void run() {
    synchronized(this)

            {                

                        handler.post(new MyRunnable());

                }

                notifyAll();
            }
        }
    }
    static public class MyRunnable implements Runnable {
        public void run() {
                settemp(template);
            }

        }
    }

    public static String gettemp() {
        return template;
    }
    public static void settemp(String template) {
        Recognition.template = template;
    }

}

here i will not use AsynTask because i have some other issue that is reason i choose Thread even now the problem is Thread wait do any give the suggestion for this

Use the logic below :-

new Thread(new Runnable() 
{
    @Override
    public void run() 
    {
        //do the code here such as sending request to server
        runOnUiThread(new Runnable() 
        {
            @Override
            public void run() 
            {
                //do here the code which interact with UI
            }
        });
    }
}).start();
