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
*/
@JavascriptInterface
public void showLoding() {
ProgressDialogUtil.showProgressDialog(mContext);
}

/**
* js   调用请求等待框消失
*/
@JavascriptInterface
public void dissmissLoding() {
ProgressDialogUtil.dismissProgressDialog();
}

在js中进行调用。
明天写点js h5的东西。
