title: Issues with dropdown inside Android webview
body: <p>I am just trying to make a mobile bookmark for a website with <code>webview</code>, but the mobile browser will work in hiding the menu bar (hamburger menu). It will not hide or collapse it in <code>webview</code>. It stays open, I've toggled the options commented out in the code below but nothing is working.</p>
  
  <p>Here is the code:</p>
  
  <pre><code>public class MainActivity extends AppCompatActivity {
  
  
      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);
          WebSettings webSettings = mWebView.getSettings();
          webSettings.setJavaScriptEnabled(true);
          mWebView.loadUrl(" website name");
          mWebView.setWebViewClient(new WebViewClient());
          //webSettings.setDomStorageEnabled (true);
          //mWebView.getSettings().setDomStorageEnabled(true);
          //mWebView.getSettings().setDatabaseEnabled(true);
          //mWebView.getSettings().setAppCacheEnabled(true);
          //mWebView.getSettings().setJavaScriptEnabled(false);
          //mWebView.setFocusable(false);
          //mWebView.setFocusableInTouchMode(false);
          //mWebView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
         // mWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
      }
  
  
      @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);
      }
  
  
  }
  </code></pre>
