我正在开发一个简单的应用程序 刚刚完成主屏幕.如果方向变化超过两次,则抛出错误并且应用程序强制关闭.
public class PasswordActivity extends Activity implements OnClickListener {
Button login;
Button forgot;
Button register;
private static final String PREFERENCES = "prefs";
private static final String PREFERENCES_NAME = "pref_name";
SharedPreferences settings;
private Cursor c;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
login=(Button)findViewById(R.id.login_login);
login.setOnClickListener(this);
register=(Button)findViewById(R.id.login_register);
register.setOnClickListener(this);
}
public void onClick(View v) {
}
}
