android - 使用 columnIndex 在 android 中调用 OnItem 单击

Question

任何人都可以帮助我，我不知道如何解决这个问题。实际上，我在 ListView 中获取了联系人列表，其中包含我的应用程序中的名称和号码。当我从列表中单击列表编号时，它会直接调用列表中的最后一个编号。示例:我有数字:如 abc、bca、cab，按顺序直接在 class cab OnClick 中按下。但实际上我应该调用我(点击)按下的确切数字。请建议我清除此过程。

Answer 1

您的 phoneNumber 变量在以最后一个结果结尾的循环中被替换。

您需要从您的数据列表中获取它。

将此行添加到您的onPostExecute 方法

phoneNumber = selectUsers.get(i).getPhone();

像这样

 listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> adapterView, View view,
                        int i, long l) {
                    Log.e("search", "here---------------- listener");
                    Intent callIntent = new Intent(Intent.ACTION_CALL);
                    phoneNumber = selectUsers.get(i).getPhone();
                    callIntent.setData(Uri.parse("tel:"
                            + Uri.encode(phoneNumber.trim())));
                    callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    startActivity(callIntent);
                }
            });
