您需要获取在
onCreate方法中传递的数据，而不是在声明中。
另外你不发送
Bundle，正在发送
String中
Intent。所以，你需要得到
String从
Intent。
像这样做
public class GuessOne extends ActionBarActivity { int randone; int contone; Bundle bundle; String maxPressed = ""; int maxcont = 0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.layout_guess_one); maxPressed = getIntent().getStringExtra("maxNumberPressed"); try { maxCont = Integer.parseInt(maxPressed); } catch (NumberFormatException e) { e.printStackTrace(); } } //the rest of the pre还发送这样的数据
Intent wall = new Intent(HomeActivityPro.this, GuessOne.class);wall.putExtra("maxNumberPressed", conttext.getText().toString());startActivity(wall);
