【软通动力】HarmonyOS三方件开发指南(20)-Dialog组件 原创 精华
【软通动力】HarmonyOS三方件开发指南自一月份上线以来,已经连续更新了十九期了。今天所发这篇文章将作为三方件开发指南第一期的收官之作。我庆幸社区有这么多志同道合的开发者们关注我的文章,关于三方件的讲解或许对你有所帮助,或许你有更好的建议或想法,都可以来告诉我们。
HarmonyOS的未来是强大的,因为我们广大开发者是强大的,是自信的,我也祝福各位开发者们立“鸿”鹄之志,逐梦未来!
Dialog组件功能介绍
功能介绍
Dialog组件是一个显示不同风格的自定义对话框组件,目前支持十一种风格的显示。
模拟器上运行效果
Dialog使用方法
新建工程,增加组件Har包依赖
在应用模块中添加HAR,只需要将dialoglibrary-debug.har复制到entry\libs目录下即可(由于build.gradle中已经依赖的libs目录下的*.har,因此不需要在做修改)。
修改配置文件
在entry下面的build.gradle添加library 的依赖
在代码中使用
show alert dialog

Dialog开发实现
新建一个Module
新建一个Module,类型选择HarmonyOS Library,模块名为dialoglibrary,如图
实现类
新建一个StyleDialog类,添加静态方法,代码如下:
/**
* @param context context
* @param title 对话框的title
* @param msg 对话框的提示信息
* @param listener 对话框 ok 和 cancle 的点击监听事件
* @return configbean
*/
public static ConfigBean buildMdAlert(Context context, CharSequence title, CharSequence msg,
MyDialogListener listener) {
return DialogAssigner.getInstance().assignMdAlert(context, title, msg, listener);
}
/**
* @param context context
* @param title 对话框的title
* @param list list
* @param listener 单项的item 和ok cancle 的点击事件的监听
* @return configbean
*/
public static ConfigBean buildMdSingleChoose(Context context, CharSequence title, ArrayList<ChooseBean> list,
MyItemDialogListener listener) {
return DialogAssigner.getInstance().assignMdSingleChoose(context, title, list, listener);
}
/**
* @param context context
* @param title 对话框的title
* @param list list
* @param btnListener ok cancle 的点击监听事件
* @return configbean
*/
public static ConfigBean buildMdMultiChoose(Context context, CharSequence title, ArrayList<ChooseBean> list,
MyCheckBoxItemDialogListener btnListener) {
return DialogAssigner.getInstance().assignMdMultiChoose(context, title, list, btnListener);
}
/**
* @param context context
* @param title 对话框的title
* @param hint1 输入框的hint 文字提示信息
* @param listener ok cancle 的点击监听事件
* @return configbean
*/
public static ConfigBean buildNormalInput(Context context, CharSequence title, CharSequence hint1,
MyDialogListener listener) {
return DialogAssigner.getInstance().assignNormalInput(context, title, hint1, listener);
}
新建DialogAssigner implements Assignable,代码如下:
/**
*
*/
private static DialogAssigner instance;
/**
*
*/
private DialogAssigner() {
}
/**
*
*/
public static DialogAssigner getInstance() {
if (instance == null) {
instance = new DialogAssigner();
}
return instance;
}
@Override
public ConfigBean assignMdAlert(Context context, CharSequence title, CharSequence msg, MyDialogListener listener) {
ConfigBean bean = new ConfigBean();
bean.context = context;
bean.msg = msg;
bean.title = title;
bean.listener = listener;
bean.type = DefaultConfig.ALERT_DIALOG;
bean.buildByType(bean);
return bean;
}
@Override
public ConfigBean assignNormalInput(Context context, CharSequence title, CharSequence hint1,
MyDialogListener listener) {
ConfigBean bean = new ConfigBean();
bean.context = context;
bean.listener = listener;
bean.title = title;
bean.hint1 = hint1;
bean.type = DefaultConfig.INPUT_DIALOG;
bean.buildByType(bean);
return bean;
}
@Override
public ConfigBean assignMdSingleChoose(Context context, CharSequence title, ArrayList<ChooseBean> list,
MyItemDialogListener listener) {
ConfigBean bean = new ConfigBean();
bean.context = context;
bean.title = title;
bean.itemListener = listener;
bean.type = DefaultConfig.SINGLE_DIALOG;
bean.chooseBeans.addAll(list);
bean.buildByType(bean);
return bean;
}
@Override
public ConfigBean assignMdMultiChoose(Context context, CharSequence title, ArrayList<ChooseBean> list,
MyCheckBoxItemDialogListener checkboxListener) {
ConfigBean bean = new ConfigBean();
bean.context = context;
bean.msg = title;
bean.title = title;
bean.checkBoxItemDialogListener = checkboxListener;
bean.type = DefaultConfig.MULTI_DIALOG;
bean.chooseBeans.addAll(list);
bean.buildByType(bean);
return bean;
}
新建MyDialogBuilder,实现不同dialog的生成
/**
* 根据dialog类型,生成不同类型的dialog
*
* @param bean bean
* @return configbean
*/
public ConfigBean buildByType(ConfigBean bean) {
switch (bean.type) {
case DefaultConfig.ALERT_DIALOG:
buildMdAlert(bean);
break;
case DefaultConfig.INPUT_DIALOG:
buildMdInput(bean);
break;
case DefaultConfig.SINGLE_DIALOG:
buildMdSingleChoose(bean);
break;
case DefaultConfig.MULTI_DIALOG:
buildMdMultiChoose(bean);
break;
default:
break;
}
return bean;
}

编译HAR包
利用Gradle可以将HarmonyOS Library库模块构建为HAR包,构建HAR包的方法如下:
在Gradle构建任务中,双击PackageDebugHar或PackageReleaseHar任务,构建Debug类型或Release类型的HAR。
待构建任务完成后,可以在工程目录中的styledialog> bulid > outputs > har目录中,获取生成的HAR包。

老师,这个我没太懂,例如我想用这个dialog组件,我该如何引入依赖?
这个组件点击空白处会消失,而且没有办法设置
