Question

While Developing of an Intent Android application. I want to insert data in main_actvity.java and get the same data in intent_activity.java(I want to insert data in activity_main.xml and get data in intent_test.xml)

Example: I want to login(With username and password) and display my username in next screen(after logging).

Answer 1

Using INTENT we can pass data from one Activity to another activity.

use INTENT for first Activity....

Intent i=new Intent(this, Next.class);//`this` is your class context and `Next.class` is another activity. 
i.putExtra("username",username.getText());
i.putExtra("password",password.getText());
startActivity(i);

use second Activity;

String username=getIntent().getStringExtra("username"),password=getIntent().getStringExtra("password");

Enjoy coding.....

You can use Intent as @Sushil suggested. Another way i can suggest is use of SharedPreferences . Google some good tutorials on using SharedPreferences for easy storage of app data.
