Question

我打算在android中创建一个世界时钟小部件。时钟应将所选国家/地区的时间显示为模拟时钟小部件。但是我感觉很困难，因为我是android的初学者。

我的widget.xml文件包含以下内容： -

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

  android:id="@+id/Widget"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:layout_margin="8dip"
  android:background="@drawable/myshape" >
<AnalogClock android:id="@+id/AnalogClock"
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content"
 android:dial="@drawable/widgetdial" 
 android:hand_hour="@drawable/widgethour"
 android:hand_minute="@drawable/widgetminute"/>

我正在为我的小部件使用以下配置活动： - （显示城市列表）包nEx.Software.Tutorials.Widgets.AnalogClock;

                        list[i][j] = list[i][j].substring(0, 6);
                    }
                }
            }
        }
        return list;
    }

}

除模拟时钟外，我可以在小部件中使用自己的自定义视图吗？或者还有其他方式来显示时钟吗？比如使用Imageview作为钟面并根据时间绘制表盘？

请帮帮我。!!! :(

Answer 1

此链接给出了温度计的类似示例 http://mindtherobot.com/blog/272/android-custom-ui-making-a-vintage-thermometer/ 您也可以创建自己的视图并制作时钟。

Answer 2

您可以使用自己的图纸更换时钟刻度盘，时钟指针和时钟指针。然后你将拥有自己的自定义时钟。

 android:dial="@drawable/YOUR_OWN_DIAL" 
 android:hand_hour="@drawable/YOUR_OWN_HOUR"
 android:hand_minute="@drawable/YOUR_OWN_MINUTE"

在图形布局工具中测试布局以查看其外观。
