I've got a RecyclerView which is loading the content of my String arrays which works fine, however I want to open a new activity depending on which view they have pressed.
What I have done is created an array called classes like so:
<array name="classes">
<item>ClassOne</item>
<item>ClassTwo</item>
<item>ClassThree</item>
<item>ClassFour</item>
</array>
These are stored in an array, and passed to my MainActivityList adapter below:
String[] classes = resource.getStringArray(R.array.classes);
MainActivityList adapter = new MainActivityList(titles,content, images, classes);
recyclerView.setAdapter(adapter);
I've managed to add the OnClickListener to the ViewHolder and output what class is assigned to each view to the log, however I cannot figure out or get working, how to launch another activity.
The class name would be something like ClassOne.class for example
public class MainActivityList extends RecyclerView.Adapter<MainActivityList.ViewHolder> {
private String[] mTitles;
private String[] mContent;
private String[] mClasses;
private TypedArray mImages;
private Context context;
public MainActivityList(String[] titles, String[] content, TypedArray images, String[] classes) {
this.mTitles = titles;
this.mContent = content;
this.mImages = images;
this.mClasses = classes;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup,int i) {
final View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.activity_main_card, viewGroup, false);
ViewHolder vh = new ViewHolder(v);
v.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
ViewHolder vh = (ViewHolder)v.getTag();
Log.v("DEBUG", "Clicked" + vh.classes);
}
});
return vh;
}
public void onBindViewHolder(ViewHolder holder, int position) {
holder.titleView.setText(mTitles[position]);
holder.contentView.setText(mContent[position]);
holder.imageView.setImageDrawable(mImages.getDrawable(position));
holder.classes = mClasses[position];
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView titleView;
public TextView contentView;
public ImageView imageView;
public String classes;
public ViewHolder(View v) {
super(v);
titleView = (TextView) v.findViewById(R.id.card_title);
contentView = (TextView) v.findViewById(R.id.card_content);
imageView = (ImageView)v.findViewById(R.id.card_image);
v.setTag(this);
}
}
@Override
public int getItemCount() {
return mTitles.length;
}
}
I was also looking for a solution, and I found this post: http://venomvendor.blogspot.sg/2014/07/setting-onitemclicklistener-for-recycler-view.html
By using the OnItemClickListener interface, you should be able to call startActivity
in your activity.
adapter.SetOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(View v , int position) {
// This is in an Activity so should be able to start new activity, etc.
}
});
Update: I have tested, the method mentioned in the blog worked for me.
Intent intent = new Intent(viewObject.getContext(),ActivityName.class);
viewObject.getContext().startActivity(intent);
