You must be getting NPE on getting values from EditText
Try following :
final View myLayout = inflater.inflate(R.layout.dialog_screen, null);
alert.setView(myLayout);
alert.setTitle("Set players names");
alert.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
TextView j=(TextView)myLayout.findViewById(R.id.textView2);
TextView k=(TextView)myLayout.findViewById(R.id.textView3);
EditText l=(EditText)myLayout.findViewById(R.id.player1);
EditText m=(EditText)myLayout.findViewById(R.id.player2);
String name1 = l.getText().toString();
String name2 = m.getText().toString();
j.setText(name1);
k.setText(name2);
Log.i("j"+name1, "k"+name2);
}
});
