java - 当我要去另一个 Activity 时如何停止 timer.schedule

Question

我已经关注This link在我的项目中实现 Volley。我有相同的“AppController”类。它工作正常。现在我想每 5 分钟调用一次服务器，所以我写了以下内容

Timer timer = new Timer();
    timer.schedule(new TimerTask() {
        public void run() {

            try {

                JSONObject json = new JSONObject();

                json.put("SomeData1", "SomeData1Value");
                json.put("SomeData2", "SomeData2Value");
                JsonObjectRequest j = new JsonObjectRequest("SomeUrl", json,
                        responseSaveTokenJson(), genericErrorListener());
                AppController.getInstance().addToRequestQueue(j);

            } catch (Exception e) {
                // TODO: handle exception
            }
        }
}, 0, 5000);

private Response.ErrorListener genericErrorListener() {
    return new ErrorListener() {

        public void onErrorResponse(VolleyError error) {

            try {
                Toast.makeText(getApplicationContext(),
                        "Code :" + error.networkResponse.statusCode + "\nNetwork Error\nPlease Try AgainH",
                        Toast.LENGTH_LONG).show();
            } catch (Exception e) {
                Toast.makeText(getApplicationContext(), "No internet connection availableH\n" + error.getMessage(),
                        Toast.LENGTH_LONG).show();
            }
        }

    };
}

private Response.Listener<JSONObject> responseSaveTokenJson() {
    return new Response.Listener<JSONObject>() {

        public void onResponse(JSONObject response) {
            Toast.makeText(HomeActivity.this, "RH", Toast.LENGTH_SHORT).show();

        }
    };
}

如您所见，如果请求成功，它将显示“RH” toast 。

它可以找到现在我通过做以下事情去参加另一项 Activity

Intent intent = new Intent(getApplicationContext(), SomeActivity.class);
                startActivity(intent);
                finish();

应用程序显示其他 Activity ，但问题是“它也在每 5 秒后烘烤“RH””

how to stop it from Toasting(如何停止那个定时器)

Answer 1

Intent intent = new Intent(getApplicationContext(), SomeActivity.class);
                startActivity(intent);
timer.cancel();
                finish();
