android html5 的弹出窗设置

webSettings = webView.getSettings();webSettings.setDomStorageEnabled(true);webSettings.setJavaScriptEnabled(true);webSettings.setUseWideViewPort(true);webSettings.setLoadWithOverviewMode(true);webView.setWebViewClient(new MyWebViewClient());webView.setWebChromeClient(new MyWebChromeClient());
这些是基础的没说的
class MyWebChromeClient extends WebChromeClient { //   * 覆盖默认的window.alert展示界面，避免title里显示为“：来自file:////”    @Override    public boolean onJsAlert(WebView view, String url, String message, JsResult result) {        final AlertDialog.Builder builder = new AlertDialog.Builder(view.getContext());        builder.setTitle("温馨提示")                .setMessage(message)                .setPositiveButton("确定", null);        // 不需要绑定按键事件        // 屏蔽keycode等于84之类的按键        builder.setOnKeyListener(new DialogInterface.OnKeyListener() {            public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {                return true;            }        });        // 禁止响应按back键的事件        builder.setCancelable(false);        AlertDialog dialog = builder.create();        dialog.show();        result.confirm();// 因为没有绑定事件，需要强行confirm,否则页面会变黑显示不了内容。        return true;    }    /**     * 覆盖默认的window.confirm展示界面，避免title里显示为“：来自file:////”     */    public boolean onJsConfirm(WebView view, String url, String message,                               final JsResult result) {        final AlertDialog.Builder builder = new AlertDialog.Builder(view.getContext());        builder.setTitle("温馨提示")                .setMessage(message)                .setPositiveButton("确定", new DialogInterface.OnClickListener() {                    public void onClick(DialogInterface dialog, int which) {                        result.confirm();                    }                })                .setNegativeButton("取消", new DialogInterface.OnClickListener() {                    public void onClick(DialogInterface dialog, int which) {                        result.cancel();                    }                });        builder.setOnCancelListener(new DialogInterface.OnCancelListener() {            @Override            public void onCancel(DialogInterface dialog) {                result.cancel();            }        });        // 屏蔽keycode等于84之类的按键，避免按键后导致对话框消息而页面无法再弹出对话框的问题        builder.setOnKeyListener(new DialogInterface.OnKeyListener() {            @Override            public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {                return true;            }        });        // 禁止响应按back键的事件        // builder.setCancelable(false);        AlertDialog dialog = builder.create();        dialog.show();        return true;}
在h5中可以直接alert 

还有等待窗口
public class ProgressDialogUtil {    private static Dialog progressDialog;    private static int level;//等待框展示层级，只有level=0的时候才能关闭progressDialog    public static synchronized void showProgressDialog(Context context) {            if (progressDialog == null || context != getDialogBaseContext(progressDialog)) {                dismissProgressDialog();                progressDialog = new Dialog(context, R.style.SH_MyDialogStyle);                progressDialog.setContentView(R.layout.sh_progress_dialog_layout);                progressDialog.setCancelable(true);                progressDialog.setCanceledOnTouchOutside(false);                progressDialog.show();            } else if (!progressDialog.isShowing()) {                progressDialog.show();            }        level++;    }    public static synchronized void dismissProgressDialog() {        level--;        if (level < 0) {            level = 0;        }        if (progressDialog != null && level == 0 && progressDialog.isShowing()) {            progressDialog.dismiss();            progressDialog = null;        }    }    private static Context getDialogBaseContext(Dialog dialog) {        if (dialog.getContext() instanceof ContextThemeWrapper) {            try {                Field mBase = dialog.getContext().getClass().getDeclaredField("mBase");                mBase.setAccessible(true);                return (Context) mBase.get(dialog.getContext());            } catch (Exception e) {                e.printStackTrace();            }        }        return dialog.getContext();    }}

/** * js   调用请求等待框显示 */@JavascriptInterfacepublic void showLoding() {    ProgressDialogUtil.showProgressDialog(mContext);}/** * js   调用请求等待框消失 */@JavascriptInterfacepublic void dissmissLoding() {    ProgressDialogUtil.dismissProgressDialog();}
在js中进行调用。
  明天写点js h5的东西。
