添加加载微调器的WebView的Andriod应用

我试图添加加载微调显示提前，同时加载网页感谢您的宝贵帮助添加加载微调器的WebView的Andriod应用

这里是我的代码：

package com.wEgyptianpost; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.webkit.WebSettings; 
import android.webkit.WebView; 
import android.os.Handler; 
import android.support.v4.widget.SwipeRefreshLayout; 
import android.widget.TextView; 

import java.util.Random; 

import com.google.android.gms.ads.AdRequest; 

import com.google.android.gms.ads.AdView; 

import com.wEgyptianpost.R; 


public class MainActivity extends Activity { 
    WebView view; 
    SwipeRefreshLayout mySwipeRefreshLayout; 

    private WebView mWebView; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     AdView adView = (AdView) findViewById(R.id.admob_id); 

     AdRequest adRequest = new AdRequest.Builder() 
       .setRequestAgent("android_studio:ad_template").build(); 

     adView.loadAd(adRequest); 



     mWebView = (WebView) findViewById(R.id.activity_main_webview); 

     final SwipeRefreshLayout swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipelayout); 
     final WebView mWebView = (WebView) findViewById(R.id.activity_main_webview); 
     swipeRefreshLayout.setColorSchemeResources(R.color.refresh,R.color.refresh1,R.color.refresh2); 
     swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() { 
      @Override 
      public void onRefresh() { 
       mWebView.reload(); 
       swipeRefreshLayout.setRefreshing(true); 
       (new Handler()).postDelayed(new Runnable() { 
        @Override 
        public void run() { 
         mWebView.stopLoading(); 
         swipeRefreshLayout.setRefreshing(false); 





        } 
       },10000); 
      } 
     }); 
     // Force links and redirects to open in the WebView instead of in a browser 
     //mWebView.setWebViewClient(new WebViewClient()); 

     // Enable Javascript 
     WebSettings webSettings = mWebView.getSettings(); 
     webSettings.setJavaScriptEnabled(true); 

     mWebView.getSettings().setUseWideViewPort(true); 
     mWebView.getSettings().setLoadWithOverviewMode(true); 
     // Use remote resource 
     mWebView.loadUrl("http:google.com"); 

     // Stop local links and redirects from opening in browser instead of WebView 
     mWebView.setWebViewClient(new MyAppWebViewClient()); 

     // Use local resource 
     //mWebView.loadUrl("file:android_asset/web/google.html"); 


    } 



    // Prevent the back-button from closing the app 
    @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); 
    } 



}

这里是我的活动xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    xmlns:ads="http://schemas.android.com/apk/res-auto" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    tools:context=".MainActivity"> 


    <android.support.v4.widget.SwipeRefreshLayout 
    android:id="@+id/swipelayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    tools:context=".MainActivity"> 
     <WebView 
      android:id="@+id/activity_main_webview" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" /> 


     <ScrollView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content"> 

    </ScrollView> 


</android.support.v4.widget.SwipeRefreshLayout > 

    <com.google.android.gms.ads.AdView android:id="@+id/admob_id" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignParentBottom="true" 
     ads:adSize="BANNER" 
     ads:adUnitId="ca-app-pub-1851250777225639/8300259410" 
     android:layout_gravity="center_horizontal|bottom" /> 

    <ProgressBar 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/progressBar2" 
     android:layout_gravity="center" /> 


</FrameLayout>

我向活动xml添加了进度条，但我不知道如何将其链接到主活动代码。

您可以设置Web客户端为 SET

mWebView.setWebViewClient(new WebViewClient(){ 
    @Override 
    public void onPageStarted(WebView view, String url, Bitmap favicon) { 
     super.onPageStarted(view, url, favicon); 

     progressBar.setVisibility(View.VISIBLE); 
    } 
@Override 
public boolean shouldOverrideUrlLoading(WebView view, String url) 
{ 
    view.loadUrl(url); 
    return true; 
} 
    @Override 
    public void onPageFinished(final WebView view, String url) { 

       progressBar.setVisibility(View.GONE); 
      } 
     });

为了避免Ajax calls

调用此添加它AC tivity

MyClient client=new MyClient(); 
mWebView.setWebViewClient(client); 
client.setFirsttime();

，并创建活动中的一类这样的

public void MyClient extends WebViewClient(){ 
private boolean oneTime=false; 
    public void setFirsttime(){ 
     oneTime=true; 
     } 
     @Override 
     public void onPageStarted(WebView view, String url, Bitmap favicon) { 
      super.onPageStarted(view, url, favicon); 
      if(oneTime){ 
       progressBar.setVisibility(View.VISIBLE); 
        onetime=false; 
       } 

     } 
      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) 
      { 
       view.loadUrl(url); 
       return true; 
       } 
     @Override 
     public void onPageFinished(final WebView view, String url) { 

        progressBar.setVisibility(View.GONE); 
       } 
      }

在Ajax调用onPageStarted多次调用，因此progressBar不会得到隐藏。

注意：您当您使用mWebView.loadUrl();

谢谢，但它仍然保持旋转，即使在页面加载后 –

@MahmoudRagab我编辑了我的答案 –

非常感谢你的快速帮助最后它的工作horaaaay，但它只适用于在第一页上它可以在所有页面上工作吗？对不起，如果我打扰你 –

你可以试试这个，

public class MainActivity extends Activity { 
    WebView view; 
    SwipeRefreshLayout mySwipeRefreshLayout; 
    private ProgressBar progressBar; 
    private WebView mWebView; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     AdView adView = (AdView) findViewById(R.id.admob_id); 
     progressBar= (ProgressBar)findViewById(R.id.progressBar2); 
     progressBar.setVisibility(View.VISIBLE); 
     AdRequest adRequest = new AdRequest.Builder() 
       .setRequestAgent("android_studio:ad_template").build(); 

     adView.loadAd(adRequest); 



     mWebView = (WebView) findViewById(R.id.activity_main_webview); 

     final SwipeRefreshLayout swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipelayout); 
     final WebView mWebView = (WebView) findViewById(R.id.activity_main_webview); 
     swipeRefreshLayout.setColorSchemeResources(R.color.refresh,R.color.refresh1,R.color.refresh2); 
     swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() { 
      @Override 
      public void onRefresh() { 
       mWebView.reload(); 
       swipeRefreshLayout.setRefreshing(true); 
       (new Handler()).postDelayed(new Runnable() { 
        @Override 
        public void run() { 
         mWebView.stopLoading(); 
         swipeRefreshLayout.setRefreshing(false); 

        } 
       },10000); 
      } 
     }); 
     // Force links and redirects to open in the WebView instead of in a browser 
     //mWebView.setWebViewClient(new WebViewClient()); 

     // Enable Javascript 
     WebSettings webSettings = mWebView.getSettings(); 
     webSettings.setJavaScriptEnabled(true); 

     mWebView.getSettings().setUseWideViewPort(true); 
     mWebView.getSettings().setLoadWithOverviewMode(true); 
     // Use remote resource 
     mWebView.loadUrl("http:google.com"); 

     // Stop local links and redirects from opening in browser instead of WebView 
     mWebView.setWebViewClient(new MyAppWebViewClient()); 

     // Use local resource 
     //mWebView.loadUrl("file:android_asset/web/google.html"); 
      progressBar.setVisibility(View.GONE); 
    }

谢谢，但最后的代码，使其消失已将其连接到刷新按钮不mWebview，每次打电话client.setFirsttime();这是我想达到 –

webView.setWebChromeClient(new WebChromeClient() { 
      @Override 
      public void onProgressChanged(WebView view, int newProgress) { 
       progressBar2.setProgress(newProgress); 

       //newProgress maybe is 1~100 


       super.onProgressChanged(view, newProgress); 
      }
