有没有办法在每次迭代中使用递增数字作为对具有不同数字的方法的调用

Question

What I'm showing is what I'd like to get but I don't know if it is possible. Basically I want to find 48 ImageButton views based on the index i .

ImageButton[] buttons;
for (int i = 0; i < 48; i++) {
    buttons[i] = (ImageButton) findViewById(R.id.k_i);
}

Answer 1

No that's not possible. Since you need to pass the view id which is an int . Although you can use the method findViewWithTag which allows you to find views with a specified tag ( String ). You only have to add the attribute android:tag="button_1" in the views you want to find. Then you can just do the following.

String baseTag = "button_";
ImageButton[] buttons;
for (int i = 0; i < 48; i++) {
    buttons[i] = (ImageButton) findViewWithTag(baseTag + i);
}

Answer 2

I think you can do it like this

buttons[i] = v.findViewById(Context.getResources().getIdentifier("k_"+i,"id",Context.getPackageName()));
