POfiring an Event by code in android
text
Body
copied!<p>Wondering if there is any way to build and fire an event (e.g. on click event) in android applications programmatically. </p> <p>Thanks.</p> <p>sorry, it seems question is not clear enough, let me explain a bit more:</p> <ul> <li>I have an Activity (lets call it A) with multiple views (5 ImageView for example).</li> <li>And a normal Java class (lets call it B) which is used by my Activity.</li> <li>There is an instance of B in my Activity. </li> <li>If user click on a View (Image View) the view OnClickListener calls a method in B </li> <li>In B, if operation is successful, it will call back a method in activity again. </li> <li>in activity method, It will change image or state for clicked ImageView.</li> </ul> <p>in the other hand:</p> <p>click on view (x) in Activity -------> B.doSomething() --------> A.bIsDone() -----> change image for view (x) </p> <p>with normal execution, its working and there is no problem.</p> <p>the problem is that I want to simulate this process to be automatic, my code looks like this:</p> <pre><code> while (!b.isFinished()) { try { b.doSomething(<for View x>); Thread.sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } } </code></pre> <p>The issue is that, it won't render anything, until the end of the loop. </p> <p>I tried to put the loop in another Thread, but its throwing exception:</p> <pre><code> android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. </code></pre> <p>what can i do for this issue? i was think generate an click event on view (by code), to see it can help or not.</p> <p>what is your solution? Thanks </p>
