是什么?
- view-binding for harmony
- 鸿蒙应用开发view-binding插件,消除findComponentById模版代码
- 无注解、编译期间生成Binding类文件
怎么用?
1. 在project根目录的build.gradle文件中引入view-binding的maven仓库地址和classpath
- buildscript {
- repositories {
- maven {
- url 'https://mirrors.huaweicloud.com/repository/maven/'
- }
- maven {
- url 'https://developer.huawei.com/repo/'
- }
- jcenter()
- maven{
- url 'https://dl.bintray.com/eholee/maven'
- }
- }
- dependencies {
- classpath 'com.huawei.ohos:hap:2.4.0.1'
- // view-binding
- classpath 'com.eholee.plugin:view-binding:1.0.1'
- }
- }
2. 在feature模块的build.gradle文件中引入view-binding插件
- apply plugin: 'com.huawei.ohos.hap'
- apply plugin: 'com.eholee.plugin.view-binding'
- ohos {
- ...
- }
- viewBinding{
- enable true
- }
- dependencies {
- ...
- }
3. 执行gradle sync 即可自动生成ViewBinding类,生成目录在feature中的build/generated/source/viewBinding中,
类的命名方法通过获得xml布局文件名后遵循大驼峰法(Upper Camel Case)并追加Binding后缀,如:MainAbilityBinding
4. 在需要填充布局的地方使用
主要是两个api:1. binding = AbilityMainBinding.parse(this); 2. binding.getRoot()
- public class MainAbilitySlice extends AbilitySlice {
- private AbilityMainBinding binding;
- @Override
- public void onStart(Intent intent) {
- super.onStart(intent);
- binding = AbilityMainBinding.parse(this);
- super.setUIContent(binding.getRoot());
- binding.textHelloworld.setClickedListener(new Component.ClickedListener() {
- @Override
- public void onClick(Component component) {
- new ToastDialog(MainAbilitySlice.this).setText("click").show();
- }
- });
- }
- @Override
- public void onActive() {
- super.onActive();
- }
- @Override
- public void onForeground(Intent intent) {
- super.onForeground(intent);
- }
- }
可选项
1. 提供设置根布局api
- parse(Context context, ComponentContainer parent, boolean attachToRoot)
2. 支持feature模块view-binding功能的开启与关闭:
feature中的build.gradle中设置
- viewBinding{
- enable false
- // false为关闭,插件将不会解析该feature所有的xml布局文件,
- //true为开启,插件将会解析该feature下所有的xml布局文件
- }
3. 支持针对单个xml布局文件开启与关闭view-binding功能
默认是都开启,如需关闭,需在xml根节点中加入如下信息:
- xmlns:eholee="http://schemas.eholee.com/viewbinding"
- eholee:view_binding="false"
- 示例:
- <?xml version="1.0" encoding="utf-8"?>
- <DirectionalLayout
- xmlns:ohos="http://schemas.huawei.com/res/ohos"
- xmlns:eholee="http://schemas.eholee.com/viewbinding"
- eholee:view_binding="false"
- ohos:height="match_parent"
- ohos:width="match_parent"
- ohos:background_element="$color:colorAppBackground"
- ohos:orientation="vertical">
- ...
- </DirectionalLayout>
