as you see above, I've a link variable in my webview activity with onPageFinished public. I would like to use that variable in starred line with an if statement. How could I get used that variable there?
EDIT: ofc the link will not be static as declared at start. Tats just login page. than will be many pages.
Try do this through callback
String url = "http://xxxx.com/login.php?UID=";
String uid = portal.mysharedvars.getString("uid");
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

siteview.setWebViewClient(new MywebViewClient(new Callback() {
#Override
public void onPageUrl(String url) {
if (url.toLowerCase().contains("index.php")) {
//Do what you want here
}
}
}));
final String link = url+uid;
siteview.loadUrl(link);
}
private class MywebViewClient extends WebViewClient {
Callback callback;
public MywebViewClient(Callback callback) {
this.callback = callback;
}
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
// do your stuff here
String newurl = view.getUrl();
callback.onPageUrl(newurl);
Toast.makeText(login_personel_webview.this, newurl, Toast.LENGTH_LONG).show();
}
}
public interface Callback {
void onPageUrl(String url);

I want to hide header and footer of the website but its not working Please Help
I wanted to know if it was possible to display only certain parts of a website in a WebView.
MainActivity.java
public class MainActivity extends AppCompatActivity {
private WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new myWebClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://myopenhab.org/account");
public class myWebClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
view.loadUrl("javascript:(function() { " +
"var head = document.getElementId('mainHeader').style.display='none'; " +
"})()");
}
}
#Override
// This method is used to detect back button
public void onBackPressed() {
if (webView.canGoBack()) {
webView.goBack();
} else {
// Let the system handle the back button
super.onBackPressed();
}
}
}
I have tried this Javascript Code but its showing website then after its removing
public class myWebClient extends WebViewClient
{
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
view.loadUrl("javascript:(function() { " +
"var element = document.getElementById('mainHeader');"
+ "element.parentNode.removeChild(element);" +
"var element = document.getElementById('footerRights');"+ "element.parentNode.removeChild(element);" + "})()");
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
}
I have a webview that opens up a webpage that contains a some links. However, if I click on each link, it will show "404 Not Found" error. I have done the shouldOverrideUrlLoading inside WebViewClient, but it results the same.
Please help. Thanks in advance.
this is how I set my webview:
WebView web_view = (WebView)view.findViewById(R.id.web_view);
WebSettings webSettings = web_view.getSettings();
web_view.setWebChromeClient(new WebChromeClient(){
#Override
public void onProgressChanged(WebView view, int newProgress) {
progressBar.setProgress(newProgress);
super.onProgressChanged(view, newProgress);
}
});
web_view.setWebViewClient(new WebViewClient(){
#Override
public void onPageFinished(WebView view, String url) {
progressBar.setVisibility(View.GONE);
super.onPageFinished(view, url);
}
#Override
public void shouldOverrideUrlLoading(Webview view, String url){
progressBar.setProgress(0);
progressBar.setVisibility(View.VISIBLE);
return super.shouldOverrideUrlLoading(view,url);
}
})
webSettings.setJavaScriptEnabled(true);
web_view.loadUrl("http://someurl.com");
I have also done this:
#Override
public void shouldOverrideUrlLoading(Webview view, String url){
progressBar.setProgress(0);
progressBar.setVisibility(View.VISIBLE);
view.loadUrl(url);
return true;
}
but both of them result in '404 not found'.
Any help please..
Prepare the layout to show when an error occurred instead of Web Page (a dirty 'page not found message') The layout has one button, "RELOAD" with some guide messages.
If an error occurred, Remember using boolean and show the layout we prepare.
If user click "RELOAD" button, set mbErrorOccured to false. And Set mbReloadPressed to true.
if mbErrorOccured is false and mbReloadPressed is true, it means webview loaded page successfully. 'Cause if error occurred again, mbErrorOccured will be set true on onReceivedError(...)

I am new to android development, I have tried to override onBackPress() to implement webView.GoBack(). But on pressing back key my apps getting crashed. Here is my MainActivity.java code. Am I doing something wrong ??
public class MainActivity extends AppCompatActivity {
private WebView webview;
/** Called when the activity is first created. */
public void onBackPressed (){
if (webview.isFocused() && webview.canGoBack()) {
webview.goBack();
}
else {
super.onBackPressed();
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView view = (WebView) findViewById(R.id.webView);
view.getSettings().setJavaScriptEnabled(true);
view.setWebViewClient(new MyCustomWebViewClient());
view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
view.loadUrl("http://url");
}
private class MyCustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
//hide loading image
findViewById(R.id.imageLoading1).setVisibility(View.GONE);
//show webview
findViewById(R.id.webView).setVisibility(View.VISIBLE);
}
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
if (view.canGoBack()) {
view.goBack();
} else {
view.loadUrl("file:///android_asset/index.html");
}
Toast.makeText(getBaseContext(), description, Toast.LENGTH_LONG).show();
}
}
}
Just because your webView is null. You are not referencing it anywhere. Modified your code.
public class MainActivity extends AppCompatActivity {
private WebView view;
/** Called when the activity is first created. */
public void onBackPressed (){
if (view.isFocused() && view.canGoBack()) {
view.goBack();
}
else {
super.onBackPressed();
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
view = (WebView) findViewById(R.id.webView);
view.getSettings().setJavaScriptEnabled(true);
view.setWebViewClient(new MyCustomWebViewClient());
view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
view.loadUrl("http://url");
}
private class MyCustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
//hide loading image
findViewById(R.id.imageLoading1).setVisibility(View.GONE);
//show webview
findViewById(R.id.webView).setVisibility(View.VISIBLE);
}
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
if (view.canGoBack()) {
view.goBack();
} else {
view.loadUrl("file:///android_asset/index.html");
}
Toast.makeText(getBaseContext(), description, Toast.LENGTH_LONG).show();
}
}
}
In onCreate you have:
WebView view = (WebView) findViewById(R.id.webView);
The WebView you have defined at the top has not been initialized, and is the one being used by the onBackPressed method, to fix this all you need to do is remove WebView before initializing the variable in onCreate:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
view = (WebView) findViewById(R.id.webView);
view.getSettings().setJavaScriptEnabled(true);
view.setWebViewClient(new MyCustomWebViewClient());
view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
view.loadUrl("http://url");
}
Actually you can not do directly inside the fragment. The onBackPressed can be overridden in the FragmentActivity. What you can do is:
1.Override the onBackPressed inside the activity.
2.When the onBackPressed is called, check if the instance of the current fragment is the instance showing the webview.
3.If it is, ask the fragment if the webview can go back.
4.If it is not, call the super or whatever you need
#Override
public void onBackPressed() {
Fragment webview = getSupportFragmentManager().findFragmentByTag("webview");
if (webview instanceof MyWebViewFragment) {
boolean goback = ((MyWebViewFragment)webview).canGoBack();
if (!goback)
super.onBackPressed();
}
}
On Android, I have a webView. I'm loading a url on it. Firstly, I get a login page of Facebook and after filling login details it gives me a JSON Response on same webView.
I'm using this code to load that URL but now I don't know how to get that JSON Response in a string what I got on finished of that url.
WebViewClient yourWebClient = new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
#Override
public void onPageFinished(WebView view, String url) {
wb.loadUrl("javascript:window.HTMLOUT.processHTML('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>');");
}
};
wb = (WebView) findViewById(R.id.webview);
wb.getSettings().setJavaScriptEnabled(true);
wb.getSettings().setSupportZoom(true);
wb.getSettings().setBuiltInZoomControls(true);
wb.setWebViewClient(yourWebClient);
wb.loadUrl("http://pqrs.abcde.com/facebook");
The format of JSON Response is:
{"status":"success","msg":"You have successfully logged in."}
Build a class called MyJavaScriptInterface. And MyJavaScriptInterface to WebView.
WebViewClient yourWebClient = new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
#Override
public void onPageFinished(WebView view, String url) {
wb.loadUrl("javascript:HtmlViewer.showHTML" +
"('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>');");
}
};
wb = (WebView) findViewById(R.id.webview);
wb.getSettings().setJavaScriptEnabled(true);
wb.getSettings().setSupportZoom(true);
wb.getSettings().setBuiltInZoomControls(true);
wb.setWebViewClient(yourWebClient);
wb.loadUrl("http://pqrs.abcde.com/facebook");
wb.addJavascriptInterface(new MyJavaScriptInterface(this), "HtmlViewer");
class MyJavaScriptInterface {
private Context ctx;
MyJavaScriptInterface(Context ctx) {
this.ctx = ctx;
}
#JavascriptInterface
public void showHTML(String html) {
System.out.println(html);
}
}
Note: From you are required to remove window in wb.loadUrl("javascript:...");.
And #JavascriptInterface before "public void showHTML".
You can get content from showHtml(..) in html parameter.
webView.setWebViewClient(new myWebClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(webdata);
}
public class myWebClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
What do I need to my code to make the dialog dismiss() after the webview is loaded?
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
CookieSyncManager.createInstance(this);
CookieSyncManager.getInstance().startSync();
webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new homeClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setPluginsEnabled(true);
webview.loadUrl("http://google.com");
ProgressDialog pd = ProgressDialog.show(Home.this, "",
"Loading. Please wait...", true);
}
I've tried
public void onPageFinshed(WebView view, String url){
pd.dismiss();
}
Didn't work.
:o
webview.setWebViewClient(new homeClient()); homeClient()????
try this
...
...
...
webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
if (progressBar.isShowing()) {
progressBar.dismiss();
}
}
webview.loadUrl("http://www.google.com");
}
Update::
this is a good example.
Android WebView and the Indeterminant Progress Solution
This is OK.
public class WordActivity extends Activity {
private WebView webview;
private ProgressDialog progressDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
Bundle objetbunble = this.getIntent().getExtras();
webview = (WebView) findViewById(R.id.webview);
final Activity activity = this;
webview.getSettings().setJavaScriptEnabled(true);
webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onLoadResource (WebView view, String url) {
if (progressDialog == null) {
progressDialog = new ProgressDialog(activity);
progressDialog.setMessage("Chargement en cours");
progressDialog.show();
}
}
public void onPageFinished(WebView view, String url) {
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
}
}
});
webview.loadUrl("http://www.example.com");
}
}
#Jorgesys this is not 100% accurate. If you have several iframes in a page you will have multiple onPageFinished (and onPageStarted). And if you have several redirects it may also fail. This approach i think solves all the problems:
boolean loadingFinished = true;
boolean redirect = false;
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String urlNewString) {
if (!loadingFinished) {
redirect = true;
}
loadingFinished = false;
webView.loadUrl(urlNewString);
return true;
}
#Override
public void onPageStarted(WebView view, String url) {
loadingFinished = false;
//SHOW LOADING IF IT ISNT ALREADY VISIBLE
}
#Override
public void onPageFinished(WebView view, String url) {
if(!redirect){
loadingFinished = true;
}
if(loadingFinished && !redirect){
//HIDE LOADING IT HAS FINISHED
} else{
redirect = false;
}
}
});
How are you accessing pd in onPageFinshed()? (And are you sure it's actually called when the page loads?)
In your onCreate(), try passing pd to your homeClient so that homeClient can take care of dismissing the dialog.
Your homeClient should look like this:
private class homeClient extends WebViewClient {
private ProgressDialog pd;
public homeClient(ProgressDialog pd) {
this.pd = pd;
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished (WebView view, String url) {
if (pd.isShowing()) {
pd.dismiss();
}
}
}
In your onCreate():
ProgressDialog pd = ProgressDialog.show(Fbook.this, "",
"Loading. Please wait...", true);
webview.setWebViewClient(new homeClient(pd));
If you simply want to show Progress before webPage loading in WebView. You can simply request for Window Feature Progress like
getWindow().requestFeature(Window.FEATURE_PROGRESS);
before setContentView(R.layout.blahblah);
and show it progress in onProgressChanged like
final Activity context= this;
webview.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView webView, int progress)
{
activity.setProgress(progress * 1000);
}
});
And if you want to add you own ProgressDialog then use WebviewClient
webView.setWebViewClient(new WebViewClient() {
ProgressDialog rogressDialog ;
#Override
public void onPageStarted(WebView view, String url, Bitmap bitmap) {
progressDialog = ProgressDialog.show(context, "Loading...", "Please wait...");//where context = YourActivity.this;
super.onPageStarted(view, url, bitmap);
}
#Override
public void onPageFinished(WebView view, String url) {
progressDialog .dismiss();
super.onPageFinished(view, url);
}
});
webView.loadUrl(url);
wv1.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(Entertainment.this, description, Toast.LENGTH_SHORT).show();
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
progressDialog.show();
}
#Override
public void onPageFinished(WebView view, String url) {
progressDialog.dismiss();
String webUrl = wv1.getUrl();
}
});
wv1.loadUrl(url);
The above code will show a progress dialogue for every incoming link you navigate to the in webview.
