public class personalData extends AppCompatActivity {

EditText[] mUserPersonalInfo = new EditText[7] ;     // 0=FULL_NAME
RadioGroup mSex;                    // 1 =BIRTHDAY

            Intent intent = new Intent(personalData.this, professionalData.class);
            startActivity(intent);


        }

    });

}
}

我到处搜索过，但是找不到任何解决方案可以帮助我？
