Getting correct element from a array in android

Question

Below is a method in OnClickListner. I want to pass first 1=0, then i=1 likewise.

But below code shows only i=0;

            @Override
            public void onClick(View v) {
                for(i=0; i<shopTelNos.length;i++){
                    Toast.makeText(c.getApplicationContext(),"value is : "+i,Toast.LENGTH_SHORT).show();
                    break;
                }
            }
        });

Help me on this.

why there is a break; ? Give some delay in your for loop. Otherwise you will not be able to see the Toasts. As for loop will execute faster than Toast display time — Sreehari

I think the break is causing to stop after the first iteration on the loop. Try to remove the break and retest. it should do the trick

Are you sure shopTelNos.length is more than 1? The for loop you have made loops through all the elements in the shopTelNoss array. If there is only one element in that array, it will only display the message once.

First, either debug or print and check the array and its length to confirm its contents:

Log.i("ShopTel", "Array :" +shopTelNos);
Log.i("ShopTel", "Array size :" +shopTelNos.length);

Second, put a delay in between the toasts. The toasts may be overlapping.
