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
13 4 5
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 @Override11 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);//extension54 // 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 @Override12 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 keyCode42 * @param event43 * @return44 */45 @Override46 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 @Override60 protected void onDestroy() {61 //释放资源62 if (mX5WebView != null)63 mX5WebView.destroy();64 super.onDestroy();65 }66 } 六、Xml文件
