Question

我遇到了一些我似乎无法解决的代码部分问题。当我点击Shop1时，ListView中会出现三个项目，即位置，联系人和约会。当我选择其中一个时，我想知道如何进入另一个活动。例如，如果我想点击位置，我希望它带我到另一个布局文件。帮助会很棒！

以下是一些照片：

如果还有其他需要请告诉我！

Answer 1

尝试使用startActivity(new Intent(getBaseContext(), activityToStart.class));

为什么要将作为ID的float转换为int？你应该只使用作为位置的int值。

     list.setOnItemClickListener(new OnItemClickListener() {
                        @Override
                        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                            switch (i)
                            {
                                case 0: // Location
startActivity(new Intent(getBaseContext(), LocationActivity.class));

                                    break;
                                case 1: // Contact
;startActivity(new Intent(getBaseContext(), ContactActivity.class));

                                    break;
                                case 2: // Appointment
startActivity(new Intent(getBaseContext(), AppointmentActivity.class));

                                    break;
                            }
                        }
                    });

如果您知道单击项目的“行ID”，则可以使用浮点值。
