请直接在这里发布您的源代码，而不是链接。 – Abhi

在我看来，toll_bar.xml是不必要的。

首先，在activity_main.xml，请更改

<include 
    android:id="@+id/toolbar" 
    layout="@layout/toll_bar" />

到

<android.support.v7.widget.Toolbar 
    android:id="@+id/toolbar" 
    android:layout_width="match_parent" 
    android:layout_height="?android:actionBarSize" 
    android:background="@color/colorPrimary"/>

二，创建一个名为toolbar.xml把它放到res/menu目录中的菜单文件。

三，这里是新MainActivity.java

public class MainActivity extends AppCompatActivity { 

    Toolbar toolbar; 


    @Override 
    public void onBackPressed() { 
     if (mWebView.canGoBack()) { 
      mWebView.goBack(); 
     } else { 
      super.onBackPressed(); 
     } 
    } 

    private WebView mWebView; 

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

     toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 

     mWebView = (WebView) findViewById(R.id.activity_main_webview); 
     mWebView.loadUrl("http://beta.html5test.com/"); 
     mWebView.loadUrl("file:///android_asset/Html36289/index.html"); 
     // Force links and redirects to open in the WebView instead of in a browser 
     mWebView.setWebViewClient(new WebViewClient()); 
     // Stop local links and redirects from opening in browser instead of WebView 
     mWebView.setWebViewClient(new MyAppWebViewClient()); 

     mWebView.getSettings().setJavaScriptEnabled(true); 
    } 

    private boolean isActivityStarted(Intent aIntent) { 
     try { 
      startActivity(aIntent); 
      return true; 
     } catch (ActivityNotFoundException e) { 
      return false; 
     } 
    } 

    public void onClickRateThisApp() { 
     Intent intent = new Intent(Intent.ACTION_VIEW); 
     intent.setData(Uri.parse("market://details?id=com.supercell.hayday")); 
     if (!isActivityStarted(intent)) { 
      intent.setData(Uri.parse("https://play.google.com/store/apps/details?id=com.package.name")); 
      if (!isActivityStarted(intent)) { 
       Toast.makeText(this, "Could not open Android market, please check if the market app installed or not. Try again later", Toast.LENGTH_SHORT).show(); 
      } 
     } 
    } 

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

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     switch (item.getItemId()) { 
      case R.id.menu_about: 
       //click the about button 
       break; 
      case R.id.menu_share: 
       //click the share button 
       break; 
      case R.id.menu_rate: 
       onClickRateThisApp();// param view is unnecessary 
       break; 
     } 
     return true; 
    } 
}

我希望这将帮助你。如果是这样，请采纳我的答案。:-祝你有美好的一天。

谢谢你的回答，我尝试了不同的解决方案，它工作。 https://www.youtube.com/watch?v=U39RsxrWhIA –

您可以添加此代码，这将帮助你。

Intent share = new Intent(android.content.Intent.ACTION_SEND); 
       share.setType("text/plain"); 
       share.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET); 

           startActivity(Intent.createChooser(share, ""));

这将打开应用程序的多个共享选项。这有助于我与其他人分享。
