Hi, I'm a beginner android developer, and I've only been coding for a few months. I'm testing some layouts in a project using eclipse, and I'm following the guidelines from a textbook (beginning android 2.0) and I'm getting some rather perplexing errors. The first error is in my main.xml. my code is as follows:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <ImageView android:id="@+id/icon" android:padding="2dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ok" /> <TextView android:id="@+id/label" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="40sp" /> </LinearLayout> everything seems to work other than this line under ImageView: android:src="@drawable/ok" I'm not entirely sure what this means, but the error says: Error:No resource found that matches the given name (at 'src' with value '@drawable/ok'). Seeing as I don't really understand what I'm supposed to be referencing, so I don't know where to begin fixing it. Secondly, I'm getting two similar errors concerning how to create fields in R.Java. My code for Layout_Testing.java (my main .java file) is as follows: import android.app.ListActivity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.TextView; public class Layout_Testing extends ListActivity { private TextView selection; private static final String[] items={"lorem", "ipsum", "dolor", "sit", "amet", "consectetuer", "adipiscing", "elit", "morbi", "vel", "ligula", "vitae", "arcu", "aliquet", "mollis", "etiam", "vel", "erat", "placerat", "ante", "porttitor", "sodales", "pellentesque", "augue", "purus"}; @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); setListAdapter(new ArrayAdapter<String>(this, R.layout.row, R.id.label, items)); selection=(TextView)findViewById(R.id.selection); } public void onListItemClick(ListView parent, View v, int position, long id) { selection.setText(items[position]); } } everything works up until I try to set the list adapter (setListAdapter): setListAdapter(new ArrayAdapter<String>(this, R.layout.row, R.id.label, items)); selection=(TextView)findViewById(R.id.selection); } The error I'm getting says that they can't be resolved, so I attempted to create a new field in R.Java. But, seeing as R.Java is derived, I can't edit it. It just reverts back to before my edits. I'm really confused about this and I figured this was the place to go for help. Thanks for reading this, and if you have any suggestions, please email me or respond!
