Question

在网页上显示其他解决方案时，网页上的其他解决方案仍然重复或下降，而不是使用我的代码

所以我是noob阶段的HTML / CSS开发人员。我正在尝试为我的网站构建一个简单的webview应用程序。现在，当我从github获得一个用于webview的项目时，似乎“文件上传”在webview中不起作用，但在浏览器中就像一个魅力。请帮帮我。此外，如果应用程序的整个意图只是将网站转换为Android应用程序，如果您认为github上有一个项目可以很容易达到我的目的（webview中的文件上传），那么你可以给我链接！谢谢！

我的MainActivity.java：

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;


public class MainActivity extends Activity {

    private WebView mWebView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mWebView = (WebView) findViewById(R.id.activity_main_webview);

        // Force links and redirects to open in the WebView instead of in a browser
        mWebView.setWebViewClient(new WebViewClient());

        // Enable Javascript
        WebSettings webSettings = mWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);

        // Use remote resource
        // mWebView.loadUrl("http://example.com");

        // Stop local links and redirects from opening in browser instead of WebView
        // mWebView.setWebViewClient(new MyAppWebViewClient());

        // Use local resource
        mWebView.loadUrl("file:///android_asset/www/index.html");
    }

    // Prevent the back-button from closing the app
    @Override
    public void onBackPressed() {
        if(mWebView.canGoBack()) {
            mWebView.goBack();
        } else {
            super.onBackPressed();
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

根据您的期望，我认为您希望在WebView中启用繁重的任务。为此，您需要启用 ChromeClient ，

mWebView.setWebChromeClient(new MyWebViewClient());

你的MyWebViewClient类将是，

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mWebView = (WebView) findViewById(R.id.activity_main_webview);

        // Force links and redirects to open in the WebView instead of in a browser
        mWebView.setWebViewClient(new WebViewClient());
        mWebView.setWebChromeClient(new MyWebViewClient());    // HERE

        // Enable Javascript
        WebSettings webSettings = mWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);

        // Use remote resource
        // mWebView.loadUrl("http://example.com");

        // Stop local links and redirects from opening in browser instead of WebView
        // mWebView.setWebViewClient(new MyAppWebViewClient());

        class MyWebViewClient extends WebChromeClient {
            @Override
            public void onProgressChanged(WebView view, int newProgress) {
                super.onProgressChanged(view, newProgress);
            }

            @Override
            public void onReceivedTitle(WebView view, String title) {
                super.onReceivedTitle(view, title);
            }    
        }

        // Use local resource
        mWebView.loadUrl("file:///android_asset/www/index.html");
    }

希望这能帮到你！

<input type =“file”/>无法在webview
