How can I change the ID from an ImageView

I'm trying to change the ID for an ImageView, but I don't know how to do it. please Help.

import android.os.Bundle;
import android.view.View;

public class MovieActivity extends Activity {

    @InjectView(R.id.movieTitle) TextView mTitleLabel;
    @InjectView(R.id.movieImage) ImageView mMovieImage;

    public void onCreate(Bundle savedInstanceState) {

        // The rest of the code is omitted for brevity :)

    public void updateDisplay(Movie movie) {
public class Movie {
    private String mTitle;
    private int mYearReleased;
    private int mImageId;

    public int getImageId() {
        return mImageId;

    public void setImageId(int id) {
        mImageId = id;

    public String getTitle() {
        return mTitle;

    public void setTitle(String title) { 
        mTitle = title;

you can change id of Image View in xml file not in java file go to your xml layout and in ImageView Tag change property of Id like this

Not sure, but are you wanting to update the image? not change the id as your method is called updateDisplay().

if you do, you can use the line below to return the mImageId from your Movie class (I assume this has already been set elsewhere to a resource id).


Hope this helps
