问题描述
喜 我实现了使用像onUnhandledKeyEvent,shouldOverrideUrlLoading和more.If的webViewClient很多事情要添加到alertbox的支持则需要切换到WebChromeClient那么我不能做其他things.Any一个知道如何混合二者未来?
我检查$ C $下javasript警告框http://lexandera.com/2009/01/adding-alert-support-to-a-webview/

推荐答案
刚刚实施WebViewClient和WebChromeClient都喜欢这个
just implement the WebViewClient and WebChromeClient both like this
webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
progressBar = new ProgressDialog(this);
progressBar.setCancelable(true);
progressBar.setMessage("Loading...");
progressBar.show();
final Context mapp = this;
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.i("TEST", "Processing webview url click...");
// to kill activity
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
Log.i("TEST", "Finished loading URL: " + url);
if (progressBar.isShowing()) {
progressBar.dismiss();
}
}........
然后实现WebChromeClient的JavaScript警告,确认和提示
then implement the WebChromeClient forjavascript alert,confirm and prompt
webView.setWebChromeClient(new
WebChromeClient() {
@Override
public boolean onJsAlert(WebView view, String url, String message, final android.webkit.JsResult result) {
new AlertDialog.Builder(mapp)
.setTitle(R.string.title_dialog_alert)
.setMessage(message)
.setPositiveButton(android.R.string.ok,
new AlertDialog.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
result.confirm();
}
}).setCancelable(false).create().show();
return true;
}
@Override
public boolean onJsConfirm(WebView view, String url, String message, final JsResult result) {
new AlertDialog.Builder(mapp)
.setTitle(R.string.title_dialog_confirm)
.setMessage(message)
.setPositiveButton(android.R.string.ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
result.confirm();
}
}).setNegativeButton(android.R.string.cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
result.cancel();
}
}).create().show();
return true;
}
@Override
public boolean onJsPrompt(WebView view, String url, String message, String defaultValue, final JsPromptResult result) {
final LayoutInflater factory = LayoutInflater.from(mapp);
final View v = factory.inflate(R.layout.javascript_prompt_dialog, null);
((TextView)v.findViewById(R.id.prompt_message_text)).setText(message);
((EditText)v.findViewById(R.id.prompt_input_field)).setText(defaultValue);
new AlertDialog.Builder(mapp)
.setTitle(R.string.title_dialog_prompt)
.setView(v)
.setPositiveButton(android.R.string.ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = ((EditText)v.findViewById(R.id.prompt_input_field)).getText().toString();
result.confirm(value);
}
})
.setNegativeButton(android.R.string.cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
result.cancel();
}
})
.setOnCancelListener(
new DialogInterface.OnCancelListener() {
public void onCancel(DialogInterface dialog) {
result.cancel();
}
})
.show();
return true;
};
});
