Ok, guys. I know it sounds weird but what I want to achieve is when i run the app. The webview first load the link and after I enter all the details, it must automatically click a button inside the webview. Is there any possible way to do this?? I have tried with loading different links in order to open the new window.
for example,
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ourBrow = (WebView) findViewById(R.id.wvBrowser);
// cancel the web intent that default in android setting
ourBrow.setWebViewClient(new WebViewClient());
url = (TextView) findViewById(R.id.tvSC);
// webView settings
ourBrow.getSettings().setJavaScriptEnabled(true);
ourBrow.getSettings().setLoadWithOverviewMode(true);
ourBrow.getSettings().setUseWideViewPort(true);
Button SCode = (Button) findViewById(R.id.btSCode);
loadUrl("http://www.google.com.au");
this part works well, but what I want is when the length inside the search bar is equal to 4, the "search" button will automatically press
thanks so much for the help!!!
You could perhaps do this by executing some awkward javascript in the webview.
To just issue the click you could probably do something like
ourBrow.loadUrl("javascript:getElementById('button_id').click()");
Since you need to wait for the search bar to have a lenght of 4 you will probably want to register a listener on the field in javascript and issue the click there. I can't tell you the best way to do this, but you will probably need to set an eventlistener for 'change' or set onKeyUp or something similar and see if the field is of length >= 4 then issue the click. You could nest all of this in the javascript row.
Set it after the page has loaded, that is. Set a WebViewClient on the webview and load the javascript in the onPageFinished(WebView view, String url) callback or something similar.

I need to load an HTML page with a form that has only one number input field. The desired behavior is:
When the user enters some data in this field and clicks on forward button from the Android's keyboard, a function is executed and a value appears, without taking him to another page.
The problem is that when the user clicks forward, the app crashes due to a FileUriExposedException. After searching a bit, I saw that this error is related to this bug.
One of the solutions shown in (2) was add an extra invisible form field, but does anyone know another solution? Because I think that changing all HTML forms will be something much more time consuming than trying a solution via Android.
Not sure if avoiding clicking forward would help, but here is a way you can submit to the form without the user typing in the form directly, if you have them enter the number into an edittext, save its value and then use something like this. You can set the webview visibility to invisible if you want to start and then make it visible after it submits. You can find out the IDs of the elements in the form by right clicking and hitting Inspect.
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setDomStorageEnabled(true);
mWebView.loadUrl(getString(R.string.form_url));
mWebView.setWebViewClient(new WebViewClient(){
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
String fieldID;
String submitButtonID;
int numberTypedInByUser
mWebView.loadUrl("javascript: {" +
"document.getElementById('"+fieldID+"').value = '"+numberTypedInByUser+"';" +
"var z = document.getElementById('"+submitButtonID+"').click(); };");
}
});
I'm very new to developing android apps. I've edited this app I found, which was open source and have got it working to a good extent. There's some code that isn't being used at all (Like the preferences menu) but I haven't removed that as I simply don't want to mess it up. Anyway, when I view the website it's zoomed in.. I've researched the problem and found a few ways to fix it, but none have worked. The app files can be downloaded at this link: http://www.megafileupload.com/en/file/504860/App-zip.html
Thanks for any help!
Now, here's where the answer comes in.
You get the settings for your webview before you instantiate it. You need something like:
void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard); // do this first
WebView webView = (WebView) findViewById(R.id.yourwebviewid); // either this or
either the above to tie the Java object to an xml object
or create a view and add it to some parent
View parent = (View)findViewById(R.id.yourparent_layout_for_webview); // this
WebView webView = new WebView();
parent.add(webView);
webView.getSettings().setBuiltInZoomControls(true);
I’ve been making android apps for like 4-5 days now. So i’m wondering if you know how I can make a web app? I have been looking through many tutorials, but none shows directly how I can make an app that displays the content from a website, and that I can decide what I want and don’t want to display. So I really just want to customize a website into an app and make my own layout. I know how the WebView and WebContent works and all that stuff, but I don’t know how I can do what I described here.
So what do I need to learn and know to make an app like that?
You can do it by fill your xml layout with EdidText for the url and Buttons for Go, back, forward and so on, finally you need webview in this xml layout.
for the java code you can check the below sample.
public class SimpleBrowser extends Activity implements OnClickListener {
WebView myBrowser;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simplebrowser);
//here the code for initialize and set yourwebView Settings.
myBrowser= (WebView) findViewById(R.id.wvBrowser);
//the below line to enable javascript if you want that
myBrowser.getSettings().setJavaScriptEnabled(true);
//here another settings could be enabled for you your webview
myBrowser.getSettings().setLoadWithOverviewMode(true);
myBrowser.getSettings().setUseWideViewPort(true);
try {
//here the default web page
ourBrow.loadUrl("http://www.google.com");
}catch (Exception e){
e.printStackTrace();
}
}
}
and for sure you need to implements your buttons using onClicklistener to be suitable for your idea.

is there a way to hide or disable the URL field in the locationbar? In my case the device is a tablet run as a kiosk browser, so only one URL is allowed.
I fixed this by changing the code in the ChildBrowser.java to
private void navigate(String url) {
InputMethodManager imm = (InputMethodManager)this.ctx.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(edittext.getWindowToken(), 0);
if (!url.startsWith("http")) {
this.webview.loadUrl("http://" + url);
}
this.webview.loadUrl("http://www.my-only-allowed-site.example.org");
this.webview.requestFocus();
}
This works well, but is not nice. You can still see the URL. I´d like to have any of this possible solutions:
1) completely hide the URL field
2) hide the softkeyboard when clicking on the URL field
3) set the URL fonts color to black
Any idea?
thanks in advance
If you modify the source code for the plugin, you can hide the url field and close button by modifying the source code for the plugin and just comment out the following line:
toolbar.addView(back); //shows the back button
toolbar.addView(forward); //shows the forward button
//toolbar.addView(edittext); //shows the URL - comment this line out to hide the URL
toolbar.addView(close); //shows the close button
Edit: oops, I just saw from your comment that you figured this out in the same way!
I don't know anything about Phonegap but I'm assuming you're using a standard Android WebView?
If you're seeing a URL bar then it usually means that the default system browser is being invoked to handle the loading of the page. To prevent this set a WebViewClient as follows...
this.webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
});
The shouldOverrideUrlLoading(...) method is called by the host application to see if it should override the loading by using Activity Manager to find a suitable app (usually the stock browser app). Returning false means the WebView instance wants to handle its own URL loading and you won't see a URL bar at all.
EDIT: If that fixes it but also looses the navigation buttons then I suggest you maintain your own history collection and provide your own buttons for back/forward/exit.
Is there some way to set an onClickListener for a webview? I've seen code here to intercept url clicks but I would just like to intercept anytime a user clicks the area the webview's on or swipes across it with their finger. I load html directly into the webview (as opposed to giving it a url) for formatting reasons and I'd really like to be able to tell any time the user clicks anywhere on the screen. I had been using a textview and that works fine, but is it doable with a webview?
Have you tried instead of an onClick, an onLongClick listener?
Taken from my recent project:
printMessageTextView.setOnLongClickListener(new OnLongClickListener() {
int active = 0;
#Override
public boolean onLongClick(View v) {
In this case, the int active = 0; is probably not needed. But should be able to listen for you.
