Card View Click on Card Move To New Activity

Question

I am new to Android programming and was working on a card layout. I was wondering, how do I make it clickable?

android:clickable="true"
android:foreground="?android:attr/selectableItemBackground"

I have that on my card widget and then I wanted to know where to put an on clickable action? I want to be able to click the card, it gets the id of the card, and then displays a new intent activity

This is my code for the activity to load the adapter

setContentView(R.layout.activity_my);


    RecyclerView recList = (RecyclerView) findViewById(R.id.cardList);
    recList.setHasFixedSize(true);
    LinearLayoutManager llm = new LinearLayoutManager(this);
    llm.setOrientation(LinearLayoutManager.VERTICAL);
    recList.setLayoutManager(llm);

    ContactAdapter ca = new ContactAdapter(createList(30));

    recList.setAdapter(ca);

Answer 1

If you used the implementation correctly, your code should go like this:

card - is the card view you instantiated to display on your ui


card.setOnClickListener(...);

In your implementation of the onClickListener, you should have this:

@Override
public void onClick(Card c ,View v) {
    Intent intent = new Intent(MyActivity.this, NextActivity.class);
    startActivity(intent);
}

that is pretty much all you need to start a new activity from the card

Answer 2

import android.view.View;

Intent intent = new Intent(view.getContext(),YourActivity.class); view.getContext().startActivity(intent);

Answer 3

You could implement the View.OnClickListener() interface to your class and then in your onCreate() method you could write findViewById(R.id.cardview).setOnClickListener(this). You could then Override the onClick() method and do what you want to do when the user clicks the card.

It would look like this:

public class MainActivity extends Activity implements View.OnClickListener()
{
     public void onCreate(Bundle savedInstanceState)
     {
       super.onCreate(savedInstanceState);
       // load the layout
       setContentView(R.layout.filters);
       // get the id of the CardView and attach an onClickListener to it
       findViewById(R.id.cardList).setOnClickListener(this)
     }
     @Override
     private void onClick(View view)
     {
        if(view.getId == R.id.cardList)
        {
         //Do something Like starting an activity
         Intent intent = new Intent(MyActivity.this, NextActivity.class);
         startActivity(intent);
        }
     }
}

Addind onClick to the cardView did it for me:

     <android.support.v7.widget.CardView
            android:foreground="?android:attr/selectableItemBackground"
            android:clickable="true"
            android:id="@+id/bankcardId"
            android:layout_width="160dp"
            android:layout_height="190dp"
            android:layout_margin="10dp"
            android:onClick="P1_bay">

Then call it in your java function as below:

    public void P1_bay(View view) {
    Toast.makeText(this, "You have clicked P1", Toast.LENGTH_LONG).show();
}

Answer 5

You can use viewHolder class as follow

public ViewHolder(View itemLayoutView) {
        super(itemLayoutView);

       itemLayoutView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v)
            {
             //  perfoem your action here
            }
        });
    }

Answer 6

In Your Adapter java file and inside of "ViewHolder" you will find:

public ContactViewHolder(final View v) {
    super(v);
}

Write blow Code:

v.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        v.getContext().startActivity(new Intent(v.getContext(), YOUR_ACTIVITY_TO_START.class));
    }
});
