单击侧滑动菜单中的项目时打开Webview

当我们点击侧面幻灯片导航中的菜单时,我正在尝试创建一个新活动。当我点击菜单时,我已经成功创建了一个新活动但是当在WebView中打开一个新活动时,侧滑块是我不想要的空白。 作为一个例子,我的应用程序与facebook应用程序相同,当我们点击任何项目时说" Newsfeed"它打开了活动,但幻灯片导航仍在那里。请让我知道锄头来实现它。谢谢你提前。

这是我的主要活动代码:

这是我点击项目时打开的活动代码。例如,我只为一项活动提供了活动代码:

package com.example.diarysystemforms;

import android.app.Activity;
import android.app.Fragment;
import android.content.Context;
import android.os.Bundle;
import android.view.Display;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class HomeFragment extends Activity {
    private static final String PIC_WIDTH = null;
    WebView mWebView; 

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_home);
        //WebView web = new WebView(this);

        WebViewClient yourWebClient = new WebViewClient()
           {
               // Override page so it's load on my view only
               @Override
               public boolean shouldOverrideUrlLoading(WebView  view, String  url)
               {
                // This line we let me load only pages inside Firstdroid Webpage
                if ( url.contains("DiarySystem") == true )
                   // Load new URL Don't override URL Link
                   return false;

                // Return true to override url loading (In this case do nothing).
                return true;
               }
           };


           // Get Web view
//         mWebView.setPadding(0, 0, 0, 0);
//          mWebView.setInitialScale(getScale());

           mWebView = (WebView) findViewById( R.id.webview ); //This is the id you gave
           mWebView.getSettings().setJavaScriptEnabled(true);  
           mWebView.getSettings().setSupportZoom(true);       //Zoom Control on web (You don't need this
                                                  //if ROM supports Multi-Touch     
           mWebView.getSettings().setBuiltInZoomControls(true); //Enable Multitouch if supported by ROM
           mWebView.setWebViewClient(yourWebClient);

           // Load URL
           mWebView.loadUrl("http://103.241.181.36:8080/DiarySystem/addvehtogrp.jsp");




       }//End of Method onCreate

}

这是我的activity_main.xml

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Framelayout to display Fragments -->
    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- Listview to display slider menu -->
    <ListView
        android:id="@+id/list_DiarySystem"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"        
        android:listSelector="@drawable/list_selector"
        android:background="@color/list_background"/>
</android.support.v4.widget.DrawerLayout>

这是fragment_home.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <WebView
        android:id="@+id/webview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@+id/textView1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="75dp" />
</RelativeLayout>

尝试删除mDrawerLayout.closeDrawers();在你的代码中。
