• Answer:

  Okay, do the following. Suppose you want to send String myUsername and String myPassword from MyFirstActivity to MySecondActivity. 1. Drag and drop a Button in your layout 2. Put an onClickListener on the Button like this: Button myButton; myButton = (Button)findViewById(R.id.button1); myButton.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(View v) { // TODO Auto-generated method stub } }); 3. Inside the onClick method, put this: Intent myIntent = new Intent(MyFirstActivity.this, MySecondActivity.class); i.putExtra("Username", myUsername); i.putExtra("Password", myPassword); startActivity(i); 4. On MySecondActivity, get those Strings: Intent i = getIntent(); String myForwardedUsername = i.getStringExtra("Username"); String myForwardedPassword = i.getStringExtra("Password");
