Button syncronized with thread android

Question

How create a button which pause the thread which is inside the loop and another button which resumes.

Runnable myRun = new Runnable(){

public void run(){

   for(int j =0 ;j<=words.length;j++){

       synchronized(this){
           try {

                wait(sleepTime);

                bt.setOnClickListener(new View.OnClickListener() {
                    public void onClick(View arg0) {

                                try {
                                    wait();
                                } catch (InterruptedException e) {
                                    e.printStackTrace();
                                }
                    }});
                bt2.setOnClickListener(new View.OnClickListener() {
                    public void onClick(View arg0) {
                        notify();

                    }
                });
                } catch (InterruptedException e) {
                e.printStackTrace();

            } }
       runOnUiThread(new Runnable(){
           public void run(){
               try {
                    et.setText(words[i]);
                    i++;
                } catch (Exception e) {
                    e.printStackTrace();
                }
           }});
      }}};

doing some stuff say words.lenght=1000 times
then suppose user want to take break in between
click pause button with id = bt this button pauses thread until and user clicks resume with id= bt1

Handler will suit for this purpose – Pragnani Mar 07 '13 at 07:18 — Pragnani, Mar 07 '13 at 07:18

Below is a hint , i think you can use for your problem. Its copied from the link i pasted at end.

A wait can be "woken up" by another process calling notify on the monitor which is being waited on whereas a sleep cannot. Also a wait (and notify) must happen in a block synchronized on the monitor object whereas sleep does not:

Object mon = ...;
synchronized (mon) {
    mon.wait();
}

At this point the currently executing thread waits and releases the monitor. Another thread may do

synchronized (mon) { mon.notify(); }(On the same mon object) and the first thread (assuming it is the only thread waiting on the monitor) will wake up.

Check Difference between wait() and sleep()

You do it like this:

How to indefinitely pause a thread in Java and later resume it?

Only you call the suspend() and other methods from your buttons' OnClickListeners
