Is this how I would do it? I'm still not seeing any text feedback on the screen when I click the button. Log will put strings into a log that's viewable in debug mode in Eclipse with the Logcat view added to the overall list of views. That's very useful for debugging purposes [obviously] without displaying anything to the app's user. However, if you want to display something on screen, you can use the Toast class http://code.google.com/android/reference/android/widget/Toast.html to display a message on screen briefly. The message will fade automatically after a short amount of time, and could be useful for what you're trying to accomplish. Raymond Thanks Raymond, I really appreciate the help. One more question though, I'm trying to use the toast widget properly, but cannot figure out the 'context' that I need to put in as a parameter. Updated code below: package test.app; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.Toast; public class test_app extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); /* Find the button from our XML-layout. */ Button b = (Button)this.findViewById(R.id.btn_open_search); b.setOnClickListener(new OnClickListener() { public void onClick(View agr0) { // Place code to handle button click here Toast.makeText(test_app, "btn-click", 9); } }); } } The error I'm getting is 'test_app' cannot be resolved, but test_app is my activity as specified in the AndroidManifest.xml. What am I doing wrong? Instead of "test_app" use "this" in Toast.makeText(). That's a special pointer (ok, Java zealots, I know that's a C/C++ term, but the concept's the same :-) ) to the object in which the function is being referenced: the test_app object of your application. I really think there should be a version of that function that doesn't require the Context parameter, so that using "this" wouldn't be necessary, but at the moment it is required. Raymond Thanks Raymond for explaining it (now I understand, the google page with info on toast did not have this tidbit). And thanks for the help! :) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
