Counting UI Elements in Android UiAutomator with a Custom Java Method

When learning Android UiAutomator, the author needed to count the number of assignment items displayed on a screen; the built‑in getChildCount() only counts rows, so they created a custom method inspired by Selenium's findElements() that iterates through UI elements.

1    //获取页面某种控件的个数
 2    public int getCountByResourceId() {
 3        int num = 0;
 4        for(int i=0;i<100;i++){
 5            try {
 6                getUiObjectByResourceIdIntance("com.gaotu100.superclass:id/assignmentitemview_upload_text", i).getText();
 7            } catch (UiObjectNotFoundException e) {
 8                //                e.printStackTrace();
 9                num = i;
10                break;
11            }
12        }
13        return num;
14    }
