Android EditText 值不显示

Question

我正在尝试从 EditTexts 中检索用户输入的值，但没有显示任何内容。这是我的代码

public class RechargeCarte extends Fragment {
private EditText cardnummer,transfersolde,bannummer;
RequestQueue requestQueue;
String s1,s2,s3;

public RechargeCarte() {
    // Required empty public constructor
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_recharge_carte, container, false);
    final Button load = (Button) rootView.findViewById(R.id.btn_load_card);
    cardnummer = (EditText) rootView.findViewById(R.id.et_card_number);
    transfersolde = (EditText) rootView.findViewById(R.id.et_transfer_solde);
    bannummer = (EditText) rootView.findViewById(R.id.et_ban_number);
    requestQueue = Volley.newRequestQueue(getActivity());
    s1 = cardnummer.getText().toString();
    s2 = bannummer.getText().toString();
    s3 = transfersolde.getText().toString();

    load.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Toast.makeText(getActivity(), "Clicked", Toast.LENGTH_SHORT).show();
            Log.e("CARDNUMBER", "aaaa"+s1);
            Log.e("BANNUMBER","aaaa"+s2);
            Log.e("TRANSFERT","aaaa"+s3);
        }
    });
    return rootView;
}
}

Toast 确实显示了，但日志结果总是“aaaa”，输入的值没有显示。

如果有人能帮忙..谢谢:))

您的代码获取 "" 值，因为它在点击之前运行....

用它解决你的问题......

load.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
           Toast.makeText(getActivity(), "Clicked", Toast.LENGTH_SHORT).show();
           s1 = cardnummer.getText().toString();
           s2 = bannummer.getText().toString();
           s3 = transfersolde.getText().toString();
           Log.e("CARDNUMBER", "aaaa"+s1);
           Log.e("BANNUMBER","aaaa"+s2);
           Log.e("TRANSFERT","aaaa"+s3);
        }
    });

享受编码............
