是的，Android WebView支持文件上传。要在WebView中实现文件上传功能，您需要执行以下步骤：
<input type="file">）和一个提交按钮（<input type="submit">）。<!DOCTYPE html> <html> <head> <title>File Upload</title> </head> <body> <form action="your_upload_url" method="post" enctype="multipart/form-data"> <input type="file" name="fileToUpload" id="fileToUpload"> <input type="submit" value="Upload File" name="submit"> </form> </body> </html> import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.webkit.WebSettings; import android.webkit.WebView; import android.webkit.WebViewClient; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); WebView webView = findViewById(R.id.webview); WebSettings webSettings = webView.getSettings(); webSettings.setJavaScriptEnabled(true); webSettings.setDomStorageEnabled(true); webSettings.setBuiltInZoomControls(false); webSettings.setSupportZoom(false); webView.setWebViewClient(new WebViewClient()); webView.loadUrl("file:///android_asset/file_upload_form.html"); } } 请注意，您需要将your_upload_url替换为您的服务器端文件上传处理URL。
<?php if (isset($_FILES['fileToUpload'])) { $target_dir = "uploads/"; $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); $uploadOk = 1; $imageFileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION)); // 检查文件是否为有效上传 if (isset($_POST["submit"])) { $uploadOk = 1; } else { echo "File was not uploaded."; $uploadOk = 0; } // 检查上传文件夹是否存在 if (!file_exists($target_dir)) { mkdir($target_dir, 0777, true); } // 尝试上传文件 if ($uploadOk == 1) { if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) { echo "The file ". htmlspecialchars(basename($_FILES["fileToUpload"]["name"])). " has been uploaded."; } else { echo "Sorry, there was an error uploading your file."; } } } else { echo "No file was uploaded."; } ?> 确保您的服务器端代码已正确配置，以便处理文件上传。
