HarmonyOS三方件开发指南(20)-Dialog组件
【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 contextcontext
* @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 contextcontext
* @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 contextcontext
* @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。
