Question

I want to repeat execution of some codes after a delay. Following is the code.

public void hintrun(int i){
     Handler handler = new Handler();       
     for(int j = 1; j< i+1;j++) {
         handler.postDelayed(new Runna(j), 1000); 
     }
}

class Runna implements Runnable { 
    private int j;
    public Runna(int j2) {
        j=j2;
    }

    public void run() {  
        // some code
    }
}

But it is not working. If say the for loop runs 3 times, then the code is run three times immediately after 1000 ms. I want a gap of 1000 ms between each execution.

Answer 1

You can simply change your code of loop this way,

for(int j = 1; j< i+1;j++)
{
    handler.postDelayed(new Runna(j), 1000*j); // 1000 * J
}
