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.
