H5獲取手機相機或相冊圖片兩種方式-Android通過webview傳遞多張照片給H5

需求目的： 手機機通過webView展示H5網頁，在特殊場景下，需要使用相機拍照或者從相冊獲取照片，上傳后臺。

完整流程效果： 如下圖
H5調用相機相冊使用組件庫方式流程

一、H5界面樣例代碼

使用html文件格式，文件直接打開就可以展示布局；一會在andriod webview中直接加載

上述代碼是前端代碼，使用vue3框架展示一個基礎加減demo界面（不重要的冗余），以及一個打開文件的按鈕以及展示圖片
在這里插入圖片描述

其中HTML5提供了元素來實現選取文件的功能，當在WebView表現為調用onShowFileChooser后，回調圖片uri列表一一獲取并展示

二、Android打開相機以及相冊的兩種方式

方式一：android 原生方式

實際效果和流程示圖
在這里插入圖片描述

1.android界面邏輯代碼
這邊使用的是kotlin語言，使用的fragment界面展示,使用binding加載了布局，以及聲明了webview組件，在webview上導入html鏈接，使本地H5界面展示


class VisitorFragment : Fragment() {private lateinit var binding: FragmentVisitorBindinglateinit var mActivity: Activityprivate lateinit var mRoot: Viewcompanion object {const val TAG = "VisitorFragment"}private var mWebViewUrl: String = "file:///android_asset/vue_android_demo.html"var mAppName = MainApplication.instance.configuration.BASE_APP_LOGIN_IDENTITYvar mSystemName = WebViewConstant.DEFAULT_SYSTEM_NAMEprivate var mVisitorAndroidJs: VisitorAndroidJs = VisitorAndroidJs(this)private var mWebView: WebView? = nullvar mAndroidId: String = WebViewConstant.DEFAULT_DEVICE_SIGNvar mApiKey: String = WebViewConstant.DEFAULT_API_KEY//回傳H5時使用的對象private var mUploadCallback: ValueCallback<Array<Uri>>? = null//拍照傳遞的路徑uriprivate var mImageUri: Uri? = null/*** onCreate方法是Activity生命周期的第一個回調方法* ，當Activity被創建時被調用。* 在這個方法中，你可以進行一些初始化的操作，比如設置布局、綁定控件、初始化數據等。** @param savedInstanceState If the fragment is being re-created from* a previous saved state, this is the state.*/override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)binding = FragmentVisitorBinding.inflate(layoutInflater)mRoot = binding.root//記錄val viewModel = ViewModelProvider(requireActivity())[DashboardViewModel::class.java]viewModel.setFragment(this)LogUtils.d(TAG, "onCreate")}/*** onCreateView方法是Fragment生命周期的回調方法，* 當Fragment創建并繪制其用戶界面時被調用。* 在這個方法中，你可以通過返回一個View對象來定義Fragment的用戶界面。* 它常用于加載布局文件、查找和初始化控件等操作。** @return*/override fun onCreateView(inflater: LayoutInflater,container: ViewGroup?,savedInstanceState: Bundle?): View {LogUtils.d(TAG, "onCreateView")initView(mRoot, layoutInflater, null)return mRoot}fun initView(parent: View?, inflater: LayoutInflater?, container: ViewGroup?) {//設置當前fragmentmAndroidId = DeviceUtils.getUniqueId(mActivity)initWebView()mWebView?.loadUrl(mWebViewUrl)//彈出展示鏈接showToast("${getString(R.string.current_develop_environment)}$mWebViewUrl")initData()}override fun onAttach(context: Context) {super.onAttach(context)mActivity = context as Activity}/*** @param msg 內容*/fun showToast(msg: String?) {val activity: Activity? = activityactivity?.runOnUiThread {Toast.makeText(activity,msg,Toast.LENGTH_SHORT).show()}}private fun initData() {}override fun onResume() {super.onResume()LogUtils.d(TAG, "onResume")}@SuppressLint("SetJavaScriptEnabled")private fun initWebView() {LogUtils.d(TAG, "initWebView")mWebView = binding.mainWebViewmWebView?.requestFocus()mWebView?.isHorizontalScrollBarEnabled = falsemWebView?.isVerticalScrollBarEnabled = falseval setting = mWebView?.settingssetting?.mixedContentMode = WebSettings.MIXED_CONTENT_ALWAYS_ALLOW;setting?.javaScriptEnabled = true//用于開啟或禁用其 DOM（文檔對象模型）存儲功能，瀏覽器緩存這些數據setting?.domStorageEnabled = true//允許訪問文件，默認允許setting?.allowFileAccess = true//設置不，會引起webView重新不急，默認NARROW_COLUMNSsetting?.layoutAlgorithm = WebSettings.LayoutAlgorithm.NARROW_COLUMNS//自動縮放setting?.setSupportZoom(true)setting?.builtInZoomControls = true//自適應屏幕setting?.useWideViewPort = truesetting?.loadWithOverviewMode = true//支持多窗口setting?.setSupportMultipleWindows(true)setting?.setAppCacheEnabled(true)setting?.domStorageEnabled = true//定位setting?.setGeolocationEnabled(true)//優先使用緩存數據，在緩存數據不存在的情況下才去獲取網絡數據setting?.cacheMode = WebSettings.LOAD_CACHE_ELSE_NETWORKsetting?.savePassword = false//設置js接口mVisitorAndroidJs.let { mWebView?.addJavascriptInterface(it, "android") }//頁面不跳轉瀏覽器mWebView?.webViewClient = object : WebViewClient() {override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {LogUtils.d(TAG, "url： $url")view.loadUrl(url)return true}override fun shouldInterceptRequest(view: WebView,request: WebResourceRequest): WebResourceResponse?

}

android layout布局

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"><WebViewandroid:id="@+id/main_web_view"android:layout_width="match_parent"android:layout_height="match_parent" /></androidx.constraintlayout.widget.ConstraintLayout>

2.獲取照片的主要思路是兩個方法：

webView官方打開文件選取方法onShowFileChooser，把網頁回傳文件

        //webView官方打開文件選取方法onShowFileChooser，把網頁回傳文件mWebView?.webChromeClient = object : WebChromeClient() {//API >=21(android 5.0.1)回調此方法override fun onShowFileChooser(webView: WebView?,filePathCallback: ValueCallback<Array<Uri>>?,fileChooserParams: FileChooserParams?): Boolean {mUploadCallback = filePathCallback//使用拍照或者打開文件mImageUri = ChoosePhotoFile.takePhoto(mActivity)//設置false會IllegalStateException: Duplicate showFileChooser resultreturn true}}

拍照或者相冊選中后界面跳回后，使用ValueCallback<Array>回傳

    fun onActivityResultResponse(requestCode: Int, resultCode: Int, intent: Intent?) {LogUtils.d(TAG,"onActivityResultResponse requestCode $requestCode, resultCode：$resultCode")if (requestCode == ChoosePhotoFile.REQUEST_CODE) {//拍照或者相冊選中后界面跳回后，結果文件的使用ChoosePhotoFile.takeActivityResult(requestCode, intent, mUploadCallback, mImageUri)}}

以上onActivityResultResponse方法需要在actvity onActivityResult方法中使用
（因為我這里是activity嵌套fragment的,如果直接在activity使用webview就不需我這太麻煩）

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {super.onActivityResult(requestCode, resultCode, data)LogUtils.d(TAG,"onActivityResult requestCode11 $requestCode, resultCode：$resultCode")//設置當前fragmentval fragment = mDashboardViewModel.fragment.valueLog.d(TAG, "fragment: $fragment")Log.d(TAG, "fragment.isResumed: ${fragment?.isResumed}")//界面返回時VisitorFragment還沒有Resumedif (fragment is VisitorFragment) {val visitorFragment: VisitorFragment = fragmentvisitorFragment.onActivityResultResponse(requestCode, resultCode, data)}}

3.打開相機和相冊的工具類

object ChoosePhotoFile {private const val TAG = "ChoosePhotoFile"const val REQUEST_CODE: Int = 12345fun takePhoto(activity: Activity): Uri {//相機可以訪問的公共位置才能存儲，獲取時需要讀取文件權限val file: String =Environment.getExternalStorageDirectory().toString() + File.separator + Environment.DIRECTORY_PICTURES + File.separatorval fileName = "Image_${SimpleDateFormat("yyyyMMdd_HHmmss").format(Date())}.jpg"val realFile = File(file, fileName)val imageUri = Uri.fromFile(realFile)LogUtils.d(TAG, "realFile：$realFile, imageUri: $imageUri")// 拍照后獲取圖片需要文件權限，界面跳轉直接拿文件不需要權限//檢查申請讀文件權限CheckPermissionUtils.requestPermissions(activity,arrayOf(Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA))//調起相機,拍一張照片val captureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri)//調起相冊，取一張照片val photoIntent = Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI)//選擇方式，拍照或者相冊val chooserIntent = Intent.createChooser(photoIntent, "Image Chooser")chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, arrayOf<Parcelable>(captureIntent))activity.startActivityForResult(chooserIntent, REQUEST_CODE)return imageUri}/*** H5針對從拍照或者相冊中選中的圖片做處理* @param imageUri 拍照返回的數據，*/fun takeActivityResult(requestCode: Int,intent: Intent?,filePathCallback: ValueCallback<Array<Uri>>?,imageUri: Uri?) {if (requestCode == REQUEST_CODE) {//從相冊獲取，返回的intentif (intent != null && intent.data != null) {var uri: Uri = intent.data as UriLogUtils.d(TAG, "file uri: $uri")filePathCallback?.onReceiveValue(arrayOf<Uri>(uri))} else {//從拍照中獲取圖片，已經返回的imageUriLogUtils.d(TAG, "take photo imageUri: $imageUri")if (imageUri != null) {filePathCallback?.onReceiveValue(arrayOf<Uri>(imageUri))} else {filePathCallback?.onReceiveValue(null)}}}}
}

方式二：使用android 組件庫是實現-朋友圈獲取照片功能

實際效果和流程示圖
在這里插入圖片描述
1.獲取照片的主要思路是兩個方法-替換

webView官方打開文件選取方法onShowFileChooser，把網頁回傳文件

        //webView官方打開文件選取方法onShowFileChooser，把網頁回傳文件mWebView?.webChromeClient = object : WebChromeClient() {//API >=21(android 5.0.1)回調此方法override fun onShowFileChooser(webView: WebView?,filePathCallback: ValueCallback<Array<Uri>>?,fileChooserParams: FileChooserParams?): Boolean {mUploadCallback = filePathCallback//使用拍照或者打開文件
//                mImageUri = ChoosePhotoFile.takePhoto(mActivity)//模擬微信朋友圈獲取照片模式LogUtils.d(TAG,"onShowFileChooser")PictureSelectorUtils.startPictureSelector(mActivity)//設置false會IllegalStateException: Duplicate showFileChooser resultreturn true}}

拍照或者相冊選中后界面跳回后，使用ValueCallback<Array>回傳

    fun onActivityResultResponse(requestCode: Int, resultCode: Int, intent: Intent?) {LogUtils.d(TAG,"onActivityResultResponse requestCode $requestCode, resultCode：$resultCode")if (requestCode == PictureSelectorUtils.REQUEST_PICTURE_SELECTOR) {LogUtils.d(TAG, "onActivityResultResponse REQUEST_PICTURE_SELECTOR")PictureSelectorUtils.takeActivityResult(requestCode, intent, mUploadCallback)}}

2.打開相機和相冊的工具類

object PictureSelectorUtils {const val REQUEST_PICTURE_SELECTOR = 10012const val TAG = "PictureSelectorUtils"fun startPictureSelector(activity: Activity) {LogUtils.d(TAG, "startPictureSelector")// 拍照后獲取圖片需要文件權限，界面跳轉直接拿文件不需要權限//檢查申請讀文件權限
//        CheckPermissionUtils.requestPermissions(
//            activity,
//            arrayOf(
//                Manifest.permission.CAMERA,
//                Manifest.permission.READ_EXTERNAL_STORAGE,
//                Manifest.permission.WRITE_EXTERNAL_STORAGE
//            )
//        )//插件里自帶了靜態權限以及權限校驗PictureSelector.create(activity).openGallery(PictureMimeType.ofImage()).imageEngine(GlideEngine) // Please refer to the Demo GlideEngine.java.isWeChatStyle(true) // 是否開啟微信圖片選擇風格.selectionMode(PictureConfig.MULTIPLE).forResult(REQUEST_PICTURE_SELECTOR)}fun getPictures(data: Intent): MutableList<Uri> {val selectList = PictureSelector.obtainMultipleResult(data)LogUtils.d(TAG, "getPicture selectList: $selectList")// 將照片路徑轉換成 Uri 列表val imageUris: MutableList<Uri> = ArrayList()if (selectList.isEmpty()) {LogUtils.d(TAG, "getPicture selectList isEmpty")return imageUris}for (imagePath in selectList) {var path = imagePath.pathLogUtils.d(TAG, "path: $path")val uri = Uri.parse(path)LogUtils.d(TAG, "uri: $uri")imageUris.add(uri)}LogUtils.d(TAG, "imageUris: ${imageUris.toString()}")return imageUris}/*** H5針對從文件鐘選中的圖片做處理*/fun takeActivityResult(requestCode: Int,intent: Intent?,filePathCallback: ValueCallback<Array<Uri>>?,) {if (requestCode == REQUEST_PICTURE_SELECTOR) {val selectList = PictureSelector.obtainMultipleResult(intent)LogUtils.d(TAG, "getPicture selectList: $selectList")// 將照片路徑轉換成 Uri 列表val imageUris: MutableList<Uri> = ArrayList()if (selectList.isEmpty()) {LogUtils.d(TAG, "getPicture selectList isEmpty")filePathCallback?.onReceiveValue(null)return}for (imagePath in selectList) {var path = imagePath.pathLogUtils.d(TAG, "path: $path")val uri = Uri.parse(path)LogUtils.d(TAG, "uri: $uri")imageUris.add(uri)}LogUtils.d(TAG, "imageUris: ${imageUris.toString()}")filePathCallback?.onReceiveValue(imageUris.toTypedArray())}}}

其中使用第三方組件庫-實現類似朋友圈獲取照片的樣式，需要引入一下依賴

    //照片獲取類微信朋友圈implementation 'com.github.LuckSiege.PictureSelector:picture_library:v2.6.0'

拍照后獲取圖片需要文件權限，界面跳轉直接拿文件不需要權限,且第三方插件庫里自帶了靜態權限以及權限請求
