腾讯TBS X5 WebView的简单使用

工作中经常涉及H5网页的加载工作,最多使用的就是安卓系统控件WebView,但是当网页内容比较多的时候,需要等待很久才能加载完,加载完后用户才能看到网页中的内容,这样用户需要等很久,体验很差。

那能不能边加载边显示呢,通过搜索发现腾讯X5WebView可以实现,相对体验要好很多,况且手Q、微信、QQ浏览器使用的该插件,故值得一试。

步骤如下:

一、下载jar包及so文件分别放到libs和jniLibs文件夹

二、添加权限

1 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /
2 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
3 <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
4 <uses-permission android:name="android.permission.INTERNET" />
5 <uses-permission android:name="android.permission.READ_PHONE_STATE" />

三、Application中初始化

 1     private void initX5WebView() {
 2         //搜集本地tbs内核信息并上报服务器,服务器返回结果决定使用哪个内核。
 3         QbSdk.PreInitCallback cb = new QbSdk.PreInitCallback() {
 4             @Override
 5             public void onViewInitFinished(boolean arg0) {
 6                 //x5內核初始化完成的回调,为true表示x5内核加载成功,否则表示x5内核加载失败,会自动切换到系统内核。
 7                 Log.d("app", " onViewInitFinished is " + arg0);
 8             }
 9  
10             @Override
11             public void onCoreInitFinished() {
12             }
13         };
14         //x5内核初始化接口
15         QbSdk.initX5Environment(getApplicationContext(), cb);
16     }

四、使用自定义X5WebView继承腾讯包下WebView

 1 import android.annotation.SuppressLint;
 2 import android.content.Context;
 3 import android.util.AttributeSet;
 4  
 5 import com.tencent.smtt.sdk.WebSettings;
 6 import com.tencent.smtt.sdk.WebSettings.LayoutAlgorithm;
 7 import com.tencent.smtt.sdk.WebView;
 8 import com.tencent.smtt.sdk.WebViewClient;
 9  
10 public class X5WebView extends WebView {
11  
12     private WebViewClient client = new WebViewClient() {
13         /**
14          * 防止加载网页时调起系统浏览器
15          */
16         public boolean shouldOverrideUrlLoading(WebView view, String url) {
17             view.loadUrl(url);
18             return true;
19         }
20     };
21  
22     @SuppressLint("SetJavaScriptEnabled")
23     public X5WebView(Context arg0, AttributeSet arg1) {
24         super(arg0, arg1);
25         this.setWebViewClient(client);
26         // this.setWebChromeClient(chromeClient);
27         // WebStorage webStorage = WebStorage.getInstance();
28         initWebViewSettings();
29         this.getView().setClickable(true);
30     }
31  
32     private void initWebViewSettings() {
33         WebSettings webSetting = this.getSettings();
34         webSetting.setJavaScriptEnabled(true);
35         webSetting.setJavaScriptCanOpenWindowsAutomatically(true);
36         webSetting.setAllowFileAccess(true);
37         webSetting.setLayoutAlgorithm(LayoutAlgorithm.NARROW_COLUMNS);
38         webSetting.setSupportZoom(true);
39         webSetting.setBuiltInZoomControls(true);
40         webSetting.setUseWideViewPort(true);
41         webSetting.setSupportMultipleWindows(true);
42         // webSetting.setLoadWithOverviewMode(true);
43         webSetting.setAppCacheEnabled(true);
44         // webSetting.setDatabaseEnabled(true);
45         webSetting.setDomStorageEnabled(true);
46         webSetting.setGeolocationEnabled(true);
47         webSetting.setAppCacheMaxSize(Long.MAX_VALUE);
48         // webSetting.setPageCacheCapacity(IX5WebSettings.DEFAULT_CACHE_CAPACITY);
49         webSetting.setPluginState(WebSettings.PluginState.ON_DEMAND);
50         // webSetting.setRenderPriority(WebSettings.RenderPriority.HIGH);
51         webSetting.setCacheMode(WebSettings.LOAD_NO_CACHE);
52  
53         // this.getSettingsExtension().setPageCacheCapacity(IX5WebSettings.DEFAULT_CACHE_CAPACITY);//extension
54         // settings 的设计
55     }
56  
57     public X5WebView(Context arg0) {
58         super(arg0);
59         setBackgroundColor(85621);
60     }
61  
62 }

五、Activity中使用

 1 /**
 2  * @author geqipeng
 3  * @date 2018/1/18
 4  */
 5  
 6 public class WebViewTestActivity extends Activity {
 7  
 8     private static final String mHomeUrl = "http://app.html5.qq.com/navi/index";
 9     private X5WebView mX5WebView;
10  
11     @Override
12     protected void onCreate(@Nullable Bundle savedInstanceState) {
13         super.onCreate(savedInstanceState);
14         setContentView(R.layout.activity_webview_test);
15         initHardwareAccelerate();
16         initView();
17     }
18  
19     /**
20      * 启用硬件加速
21      */
22     private void initHardwareAccelerate() {
23         try {
24             if (Integer.parseInt(android.os.Build.VERSION.SDK) >= 11) {
25                 getWindow()
26                         .setFlags(
27                                 android.view.WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED,
28                                 android.view.WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);
29             }
30         } catch (Exception e) {
31         }
32     }
33     
34     private void initView() {
35         mX5WebView = findViewById(R.id.x5_webview);
36         mX5WebView.loadUrl(mHomeUrl);
37     }
38  
39     /**
40      * 返回键监听
41      * @param keyCode
42      * @param event
43      * @return
44      */
45     @Override
46     public boolean onKeyDown(int keyCode, KeyEvent event) {
47         if (keyCode == KeyEvent.KEYCODE_BACK) {
48             if (mX5WebView != null && mX5WebView.canGoBack()) {
49                 mX5WebView.goBack();
50                 return true;
51             } else {
52                 return super.onKeyDown(keyCode, event);
53             }
54         }
55         return super.onKeyDown(keyCode, event);
56     }
57  
58    
59     @Override
60     protected void onDestroy() {
61         //释放资源
62         if (mX5WebView != null)
63             mX5WebView.destroy();
64         super.onDestroy();
65     }
66 }

六、Xml文件

<?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">
 
    <net.edaibu.testapplication.activity.webview.X5WebView
        android:id="@+id/x5_webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
 
</RelativeLayout>
