Body
copied!<p>I have an Android app, running a WebView that loads a certain page, also part of the app. I want to use the Android DatePicker to get a date from the user and set the value on an input inside the page in the WebView.</p> <p>The DatePickerDialog opens when the user clicks the input, but when i get the return of the date selection, i can't run the loadUrl method to set the value in the input, it gives me an error and the app crashes.</p> <p>A little bit of code (It's a test code, so don't mind if it is a bit out of context):</p> <p><strong>Class i provide to the WebView:</strong></p> <pre><code>public class webViewInterface { public void openDatePicker(){ showDialog(0); } } </code></pre> <p><strong>Javascript function on the page, called on the click of the input:</strong></p> <pre><code>function openDatePicker() { if (objAndroid != null) objAndroid.openDatePicker(); } </code></pre> <p><strong>Listener for the date selection</strong></p> <pre><code>private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() { public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { mWebView.loadUrl("javascript:setReturnDate();"); } }; </code></pre> <p><strong>Javascript function that sets a value on the input</strong></p> <pre><code>function setReturnDate() { document.getElementById('txtAgency').value = '9999'; } </code></pre> <p>Any ideas?</p> <p>Thanks in advance.</p>
