android - Cardview onclick opens a new activity

Question

Clicking a card opens an activity then clicking on another card opens another activity and so on. Is there any way to create just one activity and recognize id of the card clicked and show its corresponding data ??

Answer 1

you can send id with Intent.putExtra and then get it with Intent.getIntExtra in your activity and provide your data in activity

Here is an example that sending id and index to MyActtivity if youre using ListView:

    AdapterView.OnItemClickListener onItemClickListener = new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Intent intent = new Intent(getApplicationContext(),MyActivity.class);
        intent.putExtra("id",view.getId());
        intent.putExtra("index",position);
        startActivity(intent);
    }
};

And you can retrieve it in MyActivity like this:

Intent intent = new Intent(getIntent());
int id = intent.getIntExtra("id",0);
int index = intent.getIntExtra("index",0);
