輸入類型文件無法在android webview中工作瀏覽選項？

Question

MainActivity.java代碼在這裏：

package com.example.webrivers.controlmarketing; 
import android.support.v7.app.ActionBarActivity; 
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 ActionBarActivity { 
private WebView myWebView; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    myWebView = (WebView)findViewById(R.id.webView); 
    WebSettings webSettings = myWebView.getSettings(); 
    webSettings.setJavaScriptEnabled(true); 
    myWebView.loadUrl("http://domainname"); 
    myWebView.setWebViewClient(new WebViewClient()); 
} 

    @Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

@Override 
public boolean onPrepareOptionsMenu(Menu menu) { 
    return false; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 

    int id = item.getItemId(); 

    return super.onOptionsItemSelected(item); 
} 
} 

我使用的網站，Android的轉換中的Android 2.3.3版本，可以在Android網絡視圖中不可見的輸入文件瀏覽選項。請給任何想法，

，你不能訪問手機的文件直接，你需要在清單

<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" /> 

運行權限//這裏是你的代碼Approprite變化將讓你從手機訪問文件。

package com.example.webrivers.controlmarketing; 

    import android.support.v7.app.ActionBarActivity;

    myWebView.setWebViewClient(new WebViewClient()); 
    fixWebViewJSInterface(webView, new clsJScriptInterface(MainActivity.this), "app", "_gbjsfix"); 
} 

@SuppressLint("JavascriptInterface") 
public void fixWebViewJSInterface(WebView webview, Object jsInterface, String jsInterfaceName, String jsSignature) { 
    webview.addJavascriptInterface(jsInterface, jsInterfaceName); 

} 

public class clsJScriptInterface {
