Android: Create a new window(activity) and pass parameters to it.

Activity1.java

public class Activity1 extends Activity {
        
        @Override
	public void onCreate(Bundle savedInstanceState) {
	
		setContentView(R.layout.main);	
                
                // in the calling activity define a bundle that can contain 
                // some number of strings
		Bundle bundle = new Bundle();
		bundle.putString("paramter", "value");
                // create the intent to launch the new activity
		Intent i = new Intent(Activity1.this, Activity2.class);
                // attach the bundle to the intent and then start it
		i.putExtras(bundle);
		startActivityForResult(i,0);
	}
}

Activity2.java

public class Activity2 extends Activity {

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		setContentView(R.layout.showdefinition);
		
                // initialize a bundle and set it to the current intents bundle
		Bundle bundle = this.getIntent().getExtras();
		TextView tv = (TextView) findViewById(R.id.<viewId>);
                // you can now reference any strings defined in the bundle in 
                // the calling activity
		tv.setText(bundle.getString("paramter"));
	}
}
