Question

我在具有WebView视图的Android上开发了一个移动应用程序。在我放入Webview的网站上，有一个可以上传文件的地方，但是当我单击该地方以上传文件时，使用webview没关系。通常，他应该提供我打开文件管理器的权限，但是我什么也没有。请帮我我在下面附上我的网络视图的代码

public class WebViewActivity extends AppCompatActivity {


public String StartUrl = "https://app.vetotrack.com/?tokenPhoneValue=";
public String token;
public String EndUrl = "&tokenPhoneOs=android";
public String Url;


public String getValueToken() {

    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d("tag", "getValueToken: " + refreshedToken);
    return refreshedToken;
}


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_webview);
    getSupportActionBar().hide(); //Cacher le Title Bar
    MyFirebaseMessagingService mf = new MyFirebaseMessagingService();
    mf.onNewToken(token);
    token = getValueToken();
    Url = StartUrl + token + EndUrl;
    WebView mywebView = findViewById(R.id.myWebView);
    WebSettings webSettings = mywebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setDomStorageEnabled(true);

    mywebView.setWebViewClient(new WebViewClient(){
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if(url.contains("app.vetotrack.com")) {
                view.loadUrl(url);
            } else {
                Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
                startActivity(i);
            }
            return true;
        }
        public void onPageFinished(WebView view, String url){
        }
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl){
            Toast.makeText(getApplicationContext(), "Oh no! " + description, Toast.LENGTH_SHORT).show();

        }
    });

    mywebView.loadUrl(Url);


} }
