Buttons and Images

Hi
There are two problems with the source:
Can't use buttons for starting activities.
Can't use Images for each cards:
mCardAdapter.addCardItem(new CardItem(R.string.title_1, R.string.title_1 ));
I want use images for second argument.

How can I do these?

To use images for second argument..

in the adapter.xml add an ImageView as below:

<ImageView
            android:id="@+id/imageView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

Next, in CardItem class do the following :

public class CardItem {

 private int mTitleResource;
// This is the change to add image in the second argument..
  private int mImage;

public CardItem(int title, int image) {
    mTitleResource = title;
    mImage = image;
}

/*

public int getText() {
    return mTextResource;
}
    */


public int getTitle() {
    return mTitleResource;
}


// Add the getters for the image..
public int getImage() {
    return mImage;
} 
}

Then update the CardPagerAdapter as below:

public class CardPagerAdapter extends PagerAdapter implements CardAdapter {

private List<CardView> mViews;
private List<CardItem> mData;
private List<CardItem> mImage;  // this is the change here
private float mBaseElevation;

public CardPagerAdapter() {
    mData = new ArrayList<>();
    mViews = new ArrayList<>();
    mImage = new ArrayList<>(); // note this change.. we are creating a new ArrayList for Images..
}

public void addCardItem(CardItem item) {
    mViews.add(null);
    mData.add(item);
    mImage.add(item);  // add the image in the card...
}

public float getBaseElevation() {
    return mBaseElevation;
}

@Override
public CardView getCardViewAt(int position) {
    return mViews.get(position);
}

@Override
public int getCount() {
    return mData.size();
}

@Override
public boolean isViewFromObject(View view, Object object) {
    return view == object;
}

@Override
public Object instantiateItem(ViewGroup container, int position) {
    View view = LayoutInflater.from(container.getContext())
            .inflate(R.layout.adapter, container, false);
    container.addView(view);
    bind(mData.get(position), view);
    CardView cardView = (CardView) view.findViewById(R.id.cardView);

    if (mBaseElevation == 0) {
        mBaseElevation = cardView.getCardElevation();
    }

    cardView.setMaxCardElevation(mBaseElevation * MAX_ELEVATION_FACTOR);
    mViews.set(position, cardView);
    return view;
}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    container.removeView((View) object);
    mViews.set(position, null);
}

private void bind(CardItem item, View view) {
    TextView titleTextView = (TextView) view.findViewById(R.id.titleTextView);
   // TextView contentTextView = (TextView) view.findViewById(R.id.contentTextView);
    ImageView imageView = (ImageView) view.findViewById(R.id.imageView); // bind the image to the view
    titleTextView.setText(item.getTitle());
   // contentTextView.setText(item.getText());
    imageView.setImageResource(item.getImage());  // set the image resource
}
}

Finally in the MainActivity class you can use Images as the second argument as below:

    mCardAdapter = new CardPagerAdapter();
    //change the string resource to your drawables images in the second argument..
    mCardAdapter.addCardItem(new CardItem(R.string.title_1, R.drawable.image1));

Thats it!!
