活動（Java）

沒有碎片

 public class MyActivity extends Activity implements AdvancedWebView . Listener {

    private AdvancedWebView mWebView ;

    @ Override
    protected void onCreate ( Bundle savedInstanceState ) {
        super . onCreate ( savedInstanceState );
        setContentView ( R . layout . activity_my );

        mWebView = ( AdvancedWebView ) findViewById ( R . id . webview );
        mWebView . setListener ( this , this );
        mWebView . setMixedContentAllowed ( false );
        mWebView . loadUrl ( "http://www.example.org/" );

        // ...
    }

    @ SuppressLint ( "NewApi" )
    @ Override
    protected void onResume () {
        super . onResume ();
        mWebView . onResume ();
        // ...
    }

    @ SuppressLint ( "NewApi" )
    @ Override
    protected void onPause () {
        mWebView . onPause ();
        // ...
        super . onPause ();
    }

    @ Override
    protected void onDestroy () {
        mWebView . onDestroy ();
        // ...
        super . onDestroy ();
    }

    @ Override
    protected void onActivityResult ( int requestCode , int resultCode , Intent intent ) {
        super . onActivityResult ( requestCode , resultCode , intent );
        mWebView . onActivityResult ( requestCode , resultCode , intent );
        // ...
    }

    @ Override
    public void onBackPressed () {
        if (! mWebView . onBackPressed ()) { return ; }
        // ...
        super . onBackPressed ();
    }

    @ Override
    public void onPageStarted ( String url , Bitmap favicon ) { }

    @ Override
    public void onPageFinished ( String url ) { }

    @ Override
    public void onPageError ( int errorCode , String description , String failingUrl ) { }

    @ Override
    public void onDownloadRequested ( String url , String suggestedFilename , String mimeType , long contentLength , String contentDisposition , String userAgent ) { }

    @ Override
    public void onExternalPageRequest ( String url ) { }

}

帶有碎片（ `android.app.Fragment`碎片）

注意：如果您正在使用支持庫（ android.support.v4.app.Fragment ）中的Fragment類，請參閱下一部分（請參見下文），而不是該部分。

 public class MyFragment extends Fragment implements AdvancedWebView . Listener {

    private AdvancedWebView mWebView ;

    public MyFragment () { }

    @ Override
    public View onCreateView ( LayoutInflater inflater , ViewGroup container , Bundle savedInstanceState ) {
        View rootView = inflater . inflate ( R . layout . fragment_my , container , false );

        mWebView = ( AdvancedWebView ) rootView . findViewById ( R . id . webview );
        mWebView . setListener ( this , this );
        mWebView . setMixedContentAllowed ( false );
        mWebView . loadUrl ( "http://www.example.org/" );

        // ...

        return rootView ;
    }

    @ SuppressLint ( "NewApi" )
    @ Override
    public void onResume () {
        super . onResume ();
        mWebView . onResume ();
        // ...
    }

    @ SuppressLint ( "NewApi" )
    @ Override
    public void onPause () {
        mWebView . onPause ();
        // ...
        super . onPause ();
    }

    @ Override
    public void onDestroy () {
        mWebView . onDestroy ();
        // ...
        super . onDestroy ();
    }

    @ Override
    public void onActivityResult ( int requestCode , int resultCode , Intent intent ) {
        super . onActivityResult ( requestCode , resultCode , intent );
        mWebView . onActivityResult ( requestCode , resultCode , intent );
        // ...
    }

    @ Override
    public void onPageStarted ( String url , Bitmap favicon ) { }

    @ Override
    public void onPageFinished ( String url ) { }

    @ Override
    public void onPageError ( int errorCode , String description , String failingUrl ) { }

    @ Override
    public void onDownloadRequested ( String url , String suggestedFilename , String mimeType , long contentLength , String contentDisposition , String userAgent ) { }

    @ Override
    public void onExternalPageRequest ( String url ) { }

}

帶有來自支持庫的片段（ `android.support.v4.app.Fragment` ）

Fragment圖

改變

 mWebView . setListener ( this , this );

到

 mWebView . setListener ( getActivity (), this );

將以下代碼添加到父FragmentActivity中，以便將FragmentActivity的結果轉發到適當的Fragment實例

 public class MyActivity extends FragmentActivity implements AdvancedWebView . Listener {

 @ Override
 public void onActivityResult ( int requestCode , int resultCode , Intent intent ) {
     super . onActivityResult ( requestCode , resultCode , intent );
     if ( mFragment != null ) {
         mFragment . onActivityResult ( requestCode , resultCode , intent );
     }
 }

}

proguard（如果啟用）

 -keep class * extends android.webkit.WebChromeClient { *; }
-dontwarn im.delight.android.webview.**

clearText（非HTTPS）流量

如果您想通過普通的http而不是https提供站點或僅提供單個資源，則如果您以Android 8.1（API級別27）或更早的態度，通常沒有什麼可做的。但是，在Android 9（API級別28）及以後，默認情況下，ClearText支持被禁用。您可能必須在AndroidManifest.xml中的<application> element上設置android:usesCleartextTraffic="true"或提供自定義網絡安全配置。

特徵

優化以最佳性能和安全性
功能在Android版本上進行修補
文件上傳是自動處理的（使用AdvancedWebView.isFileUploadAvailable() ）自動處理。
- 在Android 5.0+上支持通過單個輸入字段（HTML中的multiple屬性）上傳多個文件。用於選擇文件的應用程序（即通常是畫廊或文件管理器應用程序）必須提供選擇多個文件的控件，而某些應用程序則不提供。
默認啟用JavaScript和Webstorage
包括25種口語最廣泛的語言的本地化

頁面開始/結束加載或有錯誤時接收回調

 @ Override
public void onPageStarted ( String url , Bitmap favicon ) {
    // a new page started loading
}

@ Override
public void onPageFinished ( String url ) {
    // the new page finished loading
}

@ Override
public void onPageError ( int errorCode , String description , String failingUrl ) {
    // the new page failed to load
}

下載是自動處理的，可以收聽

 @ Override
public void onDownloadRequested ( String url , String suggestedFilename , String mimeType , long contentLength , String contentDisposition , String userAgent ) {
    // some file is available for download
    // either handle the download yourself or use the code below

    if ( AdvancedWebView . handleDownload ( this , url , suggestedFilename )) {
        // download successfully handled
    }
    else {
        // download couldn't be handled because user has disabled download manager app on the device
        // TODO show some notice to the user
    }
}

啟用地理位置支持（需求<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> ）
```
 mWebView . setGeolocationEnabled ( true );
```

除了通過Web瀏覽器實現發送的添加自定義HTTP標頭

 mWebView . addHttpHeader ( "X-Requested-With" , "My wonderful app" );

定義一組允許的主機名並接收所有其他主機名的回調

 mWebView . addPermittedHostname ( "example.org" );

和

 @ Override
public void onExternalPageRequest ( String url ) {
    // the user tried to open a page from a non-permitted hostname
}

防止html頁面緩存

 boolean preventCaching = true ;
mWebView . loadUrl ( "http://www.example.org/" , preventCaching );

檢查設備上安裝的替代瀏覽器

 if ( AdvancedWebView . Browsers . hasAlternative ( this )) {
    AdvancedWebView . Browsers . openUrl ( this , "http://www.example.org/" );
}

禁用餅乾

 // disable third-party cookies only
mWebView . setThirdPartyCookiesEnabled ( false );
// or disable cookies in general
mWebView . setCookiesEnabled ( false );

允許或禁止（被動和主動）混合內容（HTTP內容在HTTPS站點內加載）

 mWebView . setMixedContentAllowed ( true );
// or
mWebView . setMixedContentAllowed ( false );

在移動和桌面模式之間切換

 mWebView . setDesktopMode ( true );
// or
// mWebView.setDesktopMode(false);

從“資產”加載html文件（例如， app/src/main/assets/html/index.html ）
```
 mWebView . loadUrl ( "file:///android_asset/html/index.html" );
```

從SD卡加載HTML文件

 // <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

if ( Environment . getExternalStorageState (). equals ( Environment . MEDIA_MOUNTED )) {
    mWebView . getSettings (). setAllowFileAccess ( true );
    mWebView . loadUrl ( "file:///sdcard/Android/data/com.my.app/my_folder/index.html" );
}

加載HTML源文本並顯示為頁面

 myWebView . loadHtml ( "<html>...</html>" );

// or

final String myBaseUrl = "http://www.example.com/" ;
myWebView . loadHtml ( "<html>...</html>" , myBaseUrl );

啟用多窗口支持

 myWebView . getSettings (). setSupportMultipleWindows ( true );
// myWebView.getSettings().setJavaScriptEnabled(true);
// myWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

myWebView . setWebChromeClient ( new WebChromeClient () {

    @ Override
    public boolean onCreateWindow ( WebView view , boolean isDialog , boolean isUserGesture , Message resultMsg ) {
        AdvancedWebView newWebView = new AdvancedWebView ( MyNewActivity . this );
        // myParentLayout.addView(newWebView, LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
        WebView . WebViewTransport transport = ( WebView . WebViewTransport ) resultMsg . obj ;
        transport . setWebView ( newWebView );
        resultMsg . sendToTarget ();

        return true ;
    }

}
