基于Android端CordovaLib的封装，在保留cordova原有功能的基础上，摆脱了必须继承CordovaActivity的限制，大幅提升UI的灵活度，可以像使用webview一样使用在Activity、Fragment甚至是自定义View中使用Cordova的能力。 同时，在原有的基础上提供更加丰富的事件回调，可应用于更加丰富的业务场景中。
- 解决了必须继承的Activity的问题，粒度小，可以像使用webview一样使用，适用于任何个性化的ui
- 提供了丰富的事件回调
implementation("com.xeonyu:cordova-webcontainer:1.0.7")该方式适用于绝大部分业务场景，集成简单，兼顾ui灵活性

/**

*/
class WebContainerActivity : CordovaWebContainerActivity() {
private lateinit var binding: ActivityWebContainerBinding
private val TAG = "WebContainerActivity"
/*布局初始化*/
override fun initContentView() {
binding = ActivityWebContainerBinding.inflate(layoutInflater)
setContentView(binding.root)
}
/*初始化Webcontainer控件*/
override fun initWebContainer(): CordovaWebContainer {
with(binding) {
webContainer.run {
/**

*/
init(this@MainActivity, LOG.VERBOSE)
return binding.webContainer
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val url = "https://baidu.com/"
binding.webContainer.loadUrl(url)
binding.webContainer.setOnPageScrollChangedListener { xOffset, yOffset, oldxOffset, oldyOffset ->
Log.i(TAG, "yOffset:$yOffset,oldyOffset:$oldyOffset")
}
binding.reloadFab.setOnClickListener {
binding.webContainer.reload()
}
}
}支持在Fragment中使用，继承CordovaWebContainerFragment即可，api跟CordovaWebContainerActivity
一致。需要注意的是Fragment的宿主Activity需要处理下页面结果回调的方法。
宿主的Activity中重写下面两个方法，写法固定
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
currentFragment?.onActivityResult(requestCode, resultCode, data)
}
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<out String>,
grantResults: IntArray,
) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults)
currentFragment?.onRequestPermissionsResult(requestCode, permissions, grantResults)
}Fragment正常使用即可，示例代码
package com.yzq.demo.fragment
/**
* @description 在Fragment中使用示例
* @author yuzhiqiang (zhiqiang.yu.xeon@gmail.com)
*/
class WebContainerFragment(val webUrl: String) : CordovaWebContainerFragment() {
private lateinit var rootView: View
private lateinit var webContainer: CordovaWebContainer
override fun initContentView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?,
): View {
rootView = layoutInflater.inflate(R.layout.fragment_web_container, container, false)
return rootView
}
override fun initWebContainer(): CordovaWebContainer {
webContainer = rootView.findViewById(R.id.web_container)
webContainer.init(requireActivity() as AppCompatActivity, LOG.VERBOSE)
return webContainer
}
override fun initWidget() {
if (webUrl.isNotEmpty()) {
webContainer.loadUrl(url = webUrl)
} else {
webContainer.loadUrl()
}
}
}如果你不希望继承指定的Activity，你可以把CordovaWebContainer作为自定义view使用。
package com.yzq.demo.activity
/**
* @description 直接使用Webcontainer控件的示例，适用于更加灵活的场景,例如你不想继承指定的Activity
* @author yuzhiqiang (zhiqiang.yu.xeon@gmail.com)
*/
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
private val TAG = "MainActivity"
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
binding.run {
toolbar.title = "基于Cordova的webview使用"
/*初始化*/
webContainer.init(this@MainActivity, LOG.VERBOSE)
/*加载url*/
// val url = "https://www.baidu.com/"
webContainer.loadUrl()
}
}
//固定写法
override fun onSaveInstanceState(outState: Bundle, outPersistentState: PersistableBundle) {
super.onSaveInstanceState(outState, outPersistentState)
binding.webContainer.onSaveInstanceState(outState)
}
//固定写法
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
binding.webContainer.onActivityResult(requestCode, resultCode, data)
}
//固定写法
override fun startActivityForResult(intent: Intent, requestCode: Int, options: Bundle?) {
binding.webContainer.startActivityForResult(requestCode)
super.startActivityForResult(intent, requestCode, options)
}
//固定写法
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<out String>,
grantResults: IntArray,
) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults)
binding.webContainer.onRequestPermissionsResult(requestCode, permissions, grantResults)
}
}传入Activity以及LifecycleOwner
/*初始化(必须)*/
webContainer.init(this, this)/*必须*/
webContainer.loadUrl(url)webContainer.addPagePbserver(PageObserver)支持以下事件监听
/*可选拦截请求 等同于shouldInterceptRequest 记得用这个*/
webContainer.webviewClient.interceptRequest { view, request, response ->
val url = request.url.toString()
Log.i(TAG, "interceptRequest:$url")
return@interceptRequest response
}/*可选 处理准备load的url 等同于 shouldOverrideUrlLoading*/
webContainer.webviewClient.overrideUrlLoading { view, request ->
Log.i(TAG, "overrideUrlLoading:${request.url}")
request.url.toString().let {
if (it.startsWith("baidu://")) {
return@overrideUrlLoading true
}
}
return@overrideUrlLoading false
}webContainer.setOnPageScrollChangedListener { xOffset, yOffset, oldxOffset, oldyOffset ->
Log.i(TAG, "yOffset:$yOffset,oldyOffset:$oldyOffset")
}其他使用跟webview api一样
组件内部已经添加如下混淆
#Cordova
-keep class org.apache.cordova.**{*;}
-keep interface org.apache.cordova.**{*;}
-keep enum org.apache.cordova.**{*;}
