I am making a simple order app. I have a recyclerview that contains products with their id, price, and quantity. When I click on a product, it opens the product details activity and I want it to display the product name and price in two textviews. I'm not sure how to transfer the data from the recyclerview to display in the textviews of product details activity.
Simple code for Pass Data
FirstActivity
Intent sendIntent = new Intent(FirstActivity.this , SecondActivity.class);
sendIntent.putExtra("firstData" , "HelloWorld1");
sendIntent.putExtra("secondData" , "HelloWorld2");
sendIntent.putExtra("thirdData" , "HelloWorld3");
startActivity(sendIntent);
SecondActivity
String firstData = getIntent().getExtras().getString("firstData");
String secondData = getIntent().getExtras().getString("secondData");
String thirdData = getIntent().getExtras().getString("thirdData");
textview1.setText(firstData);
textview2.setText(secondData);
textview3.setText(thirdData);
You can pass the data in the Intent itself by adding them as extras.
Intent intent = new Intent(context, YourActivity.class);
String id = "your_id";
int quantity = 0;
double price = 0.0d;
intent.putExtra("Id",id);
intent.putExtra("Quantity",quantity);
intent.putExtra("Price",price);
And then in your next Activity, you can extract these from Intent.
Bundle extras = getIntent().getExtras();
if(extras != null) {
String id = extras.getString("Id");
int quantity = extras.getInt("Quantity");
double price = extras.getDouble("Price");
}
Simple code for Pass Data Recyclerview TO NextActivity
RecycleView Adpter
public void onBindViewHolder(final MyViewHolder holder, final int position) {
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent sendIntent = new Intent(FirstActivity.this , SecondActivity.class);
sendIntent.putExtra("firstData" , holder.textview.getText().toString());
sendIntent.putExtra("secondData" , holder.textview1.getText().toString());
sendIntent.putExtra("thirdData" , holder.textview2.getText().toString());
startActivity(sendIntent);
}
});
}
Second Activity
super.onCreate(savedInstanceState);
setContentView(R.layout.main_frame);
String firstData = getIntent().getExtras().getString("firstData");
String secondData = getIntent().getExtras().getString("secondData");
String thirdData = getIntent().getExtras().getString("thirdData");
textview1.setText(firstData);
textview2.setText(secondData);
textview3.setText(thirdData);}
