如何在数组中创建每个数组，以便创建一个新的Point对象并将其添加到向量

public class SendText extends UiAutomatorTestCase {

    private String jsonString = "{\"A\": [[107,729],[108,728],[108,728],[108,727]," +
        "[108,727],[108,727],[108,727],[108,727],[108,727],[108,727],[108,727],[108,727],[110,724]," +
        "[114,717],[125,701],[134,685],[145,663],[157,636],[169,607],[179,583],[191,558],[196,547]," +
        "[199,540],[201,534],[202,529],[203,528],[204,525],[204,524],[204,524],[204,524],[204,524]," +
        "[204,524],[204,525],[204,530],[205,538],[207,549],[209,566],[216,602],[223,629],[229,653]," +
        "[235,671],[238,684],[241,697],[242,703],[242,707],[243,710],[243,712],[243,713],[243,713]," +
        "[243,713],[243,713],[244,713],[244,713],[244,713],[244,713],[242,709],[237,703],[230,695]," +
        "[224,684],[220,679],[215,671],[212,665],[206,658],[202,655],[200,654],[196,651],[192,648]," +
        "[189,646],[184,642],[182,641],[180,639],[179,637],[177,635],[176,634],[174,633],[173,631]," +
        "[172,630],[171,629],[170,628],[170,628],[170,627],[169,627],[169,627],[169,627],[169,627]," +
        "[169,629],[169,629]]}" ;

    public void testSendText() throws UiObjectNotFoundException {   

        JSONObject jsonObj;
        try {
            jsonObj = new JSONObject(jsonString);
            jsonObj.getJSONArray("A");
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        for(int k = 0; k < jsonString.length(); k++ ){
            Vector<Point> apoints = new Vector<Point>();
            apoints.add(new Point());

            getUiDevice().swipe((Point[])apoints.toArray(), 5);
        }
    }
}

我假设你定义了一个Point类。我们的想法是循环遍历数组A以获取每个子数组，并为每个子数组创建一个新的Point对象。

public void testSendText() throws JSONException {       
        JSONObject jsonObj = new JSONObject(jsonString);
        JSONArray  jsonArr = jsonObj.getJSONArray("A"); //get array A

        Vector<Point> apoints = new Vector<Point>();
        for(int k = 0; k < jsonArr.length(); k++ ){
            JSONArray arr = jsonArr.getJSONArray(k);
            apoints.add(new Point(arr.getInt(0), arr.getInt(1)));
        }
        getUiDevice().swipe(apoints.toArray(new Point[apoints.size()]), 5);
}

输出：
