About application UI layout problem

 Hi all,
I have a device and LCD is 800*480 resolution and density is 160. It
works perfect under cupcake, but when I push those prebuilt
applications (or download from Android Market) into my device with
Eclair via adb, the UI layout is half-
sized! The strange thing is that those applications built together
with image are normal (AlarmClock, Settings, Contacts and so on). If
set density to 240, it can show full screen but everything is
and looks ugly. Is it possible to make those apks full-screen without
rebuilding them? Does anyone have any clues for this? Thanks in

2. no id class generated in R.java (using eclipse)

Hi all,

i copied the following code from google's website :

package a.b;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.TextView;
import android.view.View;

public class Myactivity extends Activity {
    /** Called when the activity is first created. */
    public void onCreate(Bundle icicle) {

        final Button button = (Button) findViewById(R.id.button_id);
        button.setOnClickListener(new Button.OnClickListener() {
            public void onClick(View v) {
                // Perform action on click

this is for usage of buttons . but its showing error on the line
having - (R.id.button_id);

when i check my R.java file i find there is no 'id' file generated
hence the compiler has no idea of what R.id is .

can any body please help me ?
