How to assign values from an array to textviews in android

I have 4 textview such as t11,t12,t13,t14 and I have also 4 value in array val[4].

I want to store these values randomly in textviews. but I am getting little problem.

I have done following code:

  TextView t11,t12,t13,t14;
  Random r = new Random();

  for (int i = 0; i < val.length; i++) {
        int val[4]=r.nextInt(10);
        Log.d("horror", "Randm Array of VAL:" +val[i]);
  }

In the Log,there are 4 values displayed but how to display them in textviews.

I have coded but it does not work properly.

  t1[i+1].setText("" +val[i]);

and In this case,values are properly displayed, but i want to do code optimization. 

  t11.setText("" +val[0]); 
  t12.setText("" +val[1]); 
  t13.setText("" +val[2]);
  t14.setText("" +val[3]);

Thanks in advance.

you can store their references inside an array , it won't create new objects. so this should do the job 

  TextView [] textviews = {t11,t12,t13,t14};
    for(int i =0;i<textviews.length;++i){
    textviews[i].setText(val[i]);
    }

Every time you loop in for, you create another integer array. Take the definition of val out of the for loop.

For your TextView use something like,

TextView [] tv = {t11,t12,t13,t14};

and use tv for other going stuff... So now, you can getting it work by,

tv[i+1].setText("" +val[i]);
