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＆＃34; Newsfeed＆＃34;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>
答案 0 :(得分：0)
尝试删除mDrawerLayout.closeDrawers（）;在你的代码中。
