How to send string from one activity to another?

android, android-activity

Solution

You can use intents, which are messages sent between activities. In a intent you can put all sort of data, String, int, etc.

In your case, in `activity2`, before going to `activity1`, you will store a String message this way :

Intent intent = new Intent(activity2.this, activity1.class);
intent.putExtra("message", message);
startActivity(intent);

In `activity1`, in `onCreate()`, you can get the `String` message by retrieving a `Bundle` (which contains all the messages sent by the calling activity) and call `getString()` on it :

Bundle bundle = getIntent().getExtras();
String message = bundle.getString("message");

Then you can set the text in the `TextView`:

TextView txtView = (TextView) findViewById(R.id.your_resource_textview);    
txtView.setText(message);

Problem

I have a string in activity2 ``` String message = String.format( "Current Location \n Longitude: %1$s \n Latitude: %2$s", lat, lng); ``` I want to insert this string into text field in activity1. How can I do that?
