问题描述

在我的webview上传图像按钮中不起作用，但是在浏览器上它工作正常，但在我的webview应用程序中却不起作用?我的应用程序在Kotlin中而不是Java中.任何人都知道如何解决此问题.我只想通过此按钮上传图像.

In my webview upload image button not working but on browser it's working good but not in my webview app? My app is in Kotlin not Java. Anybody know how to solve this issue. I just want to upload an image by this button.

在浏览器图像上:

on browser image:

mainactivity.kt

package com.little.example
    import android.content.Intent
    import androidx.appcompat.app.AppCompatActivity
    import android.os.Bundle
    import android.os.Handler
    import android.webkit.WebBackForwardList
    import android.webkit.WebResourceRequest
    import android.webkit.WebView
    import android.webkit.WebViewClient
    import com.little.example.R
    import kotlinx.android.synthetic.main.activity_main.*
    import androidx.swiperefreshlayout.widget.SwipeRefreshLayout
    import androidx.core.app.ComponentActivity
    import androidx.core.app.ComponentActivity.ExtraData
    import androidx.core.content.ContextCompat.getSystemService
    import android.icu.lang.UCharacter.GraphemeClusterBreak.T




    class MainActivity : AppCompatActivity() {

        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            setContentView(R.layout.activity_main)
            webview.settings.javaScriptEnabled = true

            webview.loadUrl("https://little.com")
             webview.webViewClient = MyWebViewClient()



    }

    override fun onBackPressed() {
        if (webview.canGoBack()){
            webview.goBack()
        }
        else {
            super.onBackPressed()
        }
    }

    private inner class MyWebViewClient : WebViewClient() {

        override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
            if (!url.contains("little.com")) {//for example
                val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
                startActivity(intent)
                return true
            }

            view.loadUrl(url)
            return false

        }}

}

推荐答案

请在webview.settings.javaScriptEnabled = true下方的Webview设置中添加:

please add into your Webview settings, below the webview.settings.javaScriptEnabled = true:

 webview.settings.domStorageEnabled = true
