I think the reason it was suggested was to convince the thing to
recompile. I don't think that's the problem. I'd guess you are using
the m5 sdk, but the layout file you posted is m3. try changing the
id="@+id... to android:id="@+id...

[android-beginners] Re: findViewById() function return null
The relative_view.xml file is shown below:
http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10px">
It absolutely has the id -- entry:
So, I wonder if it is wrong place to call findViewById() in
onCreate().
About the timestamp, is it the modified time of the file? How does the
timestamp work with the app?

It would appear that your res/layout/relative_view.xml file does not
have a view with the id of "@+id/entry". I would have expected a
compiler error, though, complaining that R.id.entry was not found.
Perhaps your R.java file is out of sync with the contents of your res/
directory tree.
Try updating the timestamp on your res/layout/relative_view.xml file
(e.g., touch res/layout/relative_view.xml in Linux) and recompile. Or,
update res/layout/relative_view.xml to include an EditText element with
an android:id of "@+id/entry", since it would appear it doesn't have one
already.

[android-beginners] findViewById() function return null
Today, I write some simple code to implement activity. See the
following codes:
public class TestLinearView extends Activity {
private EditText edit = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
// Set activity content from layout view
setContentView(R.layout.relative_view);
// change the edit text
edit = (EditText)findViewById(R.id.entry);
edit.setText("Mysdfsadfdsafdsf");
}
}
However, the application crushed. After I debug into the app, I found
that the edit was null.
What is wrong with my codes? Please figure out.

Hi Again, It seems like I'm talking to myself, but I managed to solve the problem.
