WebView如何实现复制功能 ？_course

想实现WebView的复制功能，目前最大的问题时无法实现“文本选择”。 谁能帮忙给段代码，实现一下WebView中“文本选择”？

Android 继承BridgeWebView 写个自定义的webview。部分手机加载高度为0_course

public class AdWebView extends com.github.lzyzsd.jsbridge.BridgeWebView { private Context mContext; private MoonthimpModel moonthimpModel; private boolean messageHeight; private String mTitle; private PregressChange pregressChange; public AdWebView(Context context, AttributeSet attrs) { super(context, attrs); this.mContext = context; TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.AdWebView); messageHeight = a.getBoolean( R.styleable.AdWebView_messageHeight, false); } public void setPregressChange(PregressChange pregressChange) { this.pregressChange = pregressChange; } public AdWebView(Context context) { super(context); this.mContext = context; } Mobile mobile = new Mobile(); public void initWebView(String url) { WebSettings webSettings = getSettings(); //如果访问的页面中要与Javascript交互，则webview必须设置支持Javascript webSettings.setJavaScriptEnabled(true); //设置自适应屏幕，两者合用 webSettings.setDomStorageEnabled(true); // 解决Android 5.0上Webview默认不允许加载Http与Https混合内容 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { //两者都可以 webSettings.setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW); } //设置自适应屏幕，两者合用 webSettings.setUseWideViewPort(true); //将图片调整到适合webview的大小 webSettings.setLoadWithOverviewMode(true);// 缩放至屏幕的大小 webSettings.setAllowFileAccess(true); //设置可以访问文件 webSettings.setJavaScriptCanOpenWindowsAutomatically(true);//支持通过JS打开新窗口 webSettings.setLoadsImagesAutomatically(true);//支持自动加载图片 webSettings.setDefaultTextEncodingName("utf-8");//设置编码格式 addJavascriptInterface(this, "Android_kks"); if (messageHeight) { addJavascriptInterface(mobile, "mobile"); } if (Build.VERSION.SDK_INT >= 19) { getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE); } //设置不用系统浏览器打开,直接显示在当前Webview setWebViewClient(new BridgeWebViewClient(this) { @Override public void onPageFinished(WebView view, String url) { super.onPageFinished(view, url); LogUtils.e("onPageFinished"); if (messageHeight) { mobile.onGetWebContentHeight(); } } @Override public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) { // super.onReceivedSslError(view, handler, error); 父类的默认处理方式，内部是handler.cancel()，必须去除 handler.proceed();// 接受所有网站的证书 // handleMessage(Message msg);// 进行其他处理 } }); setWebChromeClient(new WebChromeClient() { @Override public void onProgressChanged(WebView view, int newProgress) { if (pregressChange != null) { if (newProgress == 100) { //加载完毕进度条消失 pregressChange.onComplete(); } else { //更新进度 pregressChange.onProgress(newProgress); } } super.onProgressChanged(view, newProgress); } @Override public void onReceivedTitle(WebView view, String title) { super.onReceivedTitle(view, title); if (title != null && pregressChange != null) { // pregressChange.onTitle(title); } } }); loadUrl(url); // loadUrl("https://h5.ruiccm.com/testls/190627/index.html"); // loadUrl("file:///android_asset/demo1.html"); String localVersion = ""; try { PackageInfo packageInfo = KeKeShiApp.getApp() .getPackageManager() .getPackageInfo(KeKeShiApp.getApp().getPackageName(), 0); localVersion = packageInfo.versionName; LogUtils.d("TAG", "本软件的版本号。。" + localVersion); } catch (PackageManager.NameNotFoundException e) { e.printStackTrace(); } AdUserInfoBean src = new AdUserInfoBean(); src.setDevice_uuid(PushAgent.getInstance(mContext).getRegistrationId()); if (AppSharedPrefs.getUserInfo() != null && AppSharedPrefs.getUserInfo().getUserinfo() != null && AppSharedPrefs.getUserInfo().getUserinfo().getTel() != null) { UserBean.UserInfo userinfo = AppSharedPrefs.getUserInfo().getUserinfo(); src.setPhoneNum(userinfo.getTel()); src.setBabybirthday(userinfo.getBabybirthday()); src.setBabyname(userinfo.getBabyname()); src.setBabysex(userinfo.getBabysex()); src.setIsvip((AppSharedPrefs.getUserInfo().getIsvip() ?

android webview开发中的复制问题_course

在android 的webView开发中，我现在加载一个网页，网页就有选择文本内容后获取到内容赋值给文本框的功能。但我在webView里加载这个网页后选择文本内容就没有这个功能了。我想要获得webvi
