activity

public class BorrowFlow extends BaseActivity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_borrowflow);
        if (savedInstanceState == null) {
            getSupportFragmentManager()
                    .beginTransaction()
                    .add(R.id.container, new
 
 BorrowFirst())
                    .commit();
        }
    }

fragmentOne核心跳轉方法

    private void submit() {
        // validate
        String borrowString = borrow.getText().toString().trim();
        if (TextUtils.isEmpty(borrowString)) {
            Toast.makeText(getContext(), "請填寫您的借款額度", Toast.LENGTH
 
_SHORT).show();
            return;
        }

        String dayString = day.getText().toString().trim();
        if (TextUtils.isEmpty(dayString)) {
            Toast.makeText(getContext(), "7/14", Toast.LENGTH_SHORT).show();
            return;
        }

        // TODO validate success, do something
        getFragmentManager()
                .beginTransaction
 
()
                .addToBackStack(null)  //將當前fragment加入到返回棧中
                .replace(R.id.container, new BorrowSecond()).commit();

    }
