我想从微调器中获取字符串值。我目前正在使用Volley来传递数据，但是那时并没有成功。这是我的RegisterActivity类：
public class RegUserPassClient extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_reg_user_pass_client);
final Spinner spinner = findViewById(R.id.genderSpinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.genderString, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(this);
final EditText regUserClient= (EditText) findViewById(R.id.regUserClient);
final EditText regPassClient= (EditText) findViewById(R.id.regPassClient);
final EditText regClientName = (EditText) findViewById(R.id.registerClientName);
final EditText regClientNumber = (EditText) findViewById(R.id.registerClientNumber);
final EditText regClientAddress = (EditText) findViewById(R.id.registerClientAddress);
final EditText regClientOccupation = (EditText) findViewById(R.id.registerClientOccupation);
final EditText regClientGender = (EditText) findViewById(R.id.registerClientGender);
final EditText regClientBirthDate = (EditText) findViewById(R.id.registerClientBirthDate);
final TextView clientUser = (TextView) findViewById(R.id.clientUserType);
final Button regClientBtn = (Button) findViewById(R.id.regClient);
final CheckBox toggle = (CheckBox) findViewById(R.id.checkBoxLog);
toggle.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if(b){
regPassClient.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
}else{
regPassClient.setTransformationMethod(PasswordTransformationMethod.getInstance());
}
}
});
regClientBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String username = regUserClient.getText().toString();
final String password = regPassClient.getText().toString();
final String name = regClientName.getText().toString();
final String number = regClientNumber.getText().toString();
final String gender = spinner.toString();
final String address = regClientAddress.getText().toString();
final String occupation = regClientOccupation.getText().toString();
final String birthDate = regClientBirthDate.getText().toString();
final String userType = clientUser.getText().toString();
if(!username.isEmpty() && !password.isEmpty() &&
!name.isEmpty() && !address.isEmpty() &&
!occupation.isEmpty() && !gender.isEmpty() &&
!birthDate.isEmpty() && !number.isEmpty()) {
Response.Listener<String> responseListener = new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject jsonResponse = new JSONObject(response);
boolean success = jsonResponse.getBoolean("success");
if (success) {
Intent intent = new Intent(RegUserPassClient.this, LoginRegister.class);
RegUserPassClient.this.startActivity(intent);
Toast.makeText(RegUserPassClient.this,"SuccessFully Registered! Log in your details now!",Toast.LENGTH_LONG).show();
} else {
AlertDialog.Builder builder = new AlertDialog.Builder(RegUserPassClient.this);
builder.setMessage("Username Has already been taken!")
.setNegativeButton("Retry", null)
.create()
.show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
};
RegUserPassClientRequest registerRequest = new RegUserPassClientRequest(username, password, name, number, gender, address, occupation, birthDate, userType, responseListener);
RequestQueue queue = Volley.newRequestQueue(RegUserPassClient.this);
queue.add(registerRequest);
}else if(username.isEmpty()){
regUserClient.setError("Please insert a username");
}else if(password.isEmpty()){
regPassClient.setError("Please put your password");
}else if(name.isEmpty()){
regClientName.setError("Please input your name");
}else if(number.isEmpty()){
regClientNumber.setError("Put your phone number please");
}else if(address.isEmpty()){
regClientGender.setError("Please state your gender");
}else if(occupation.isEmpty()){
regClientAddress.setError("Please put your address");
}else if(gender.isEmpty()){
regClientOccupation.setError("Please state occupation");
}else if(birthDate.isEmpty()){
regClientBirthDate.setError("Please select your Birth Date");
}
}
});
}
@Override
public void onItemSelected(AdapterView<?> parent, View view, int i, long l) {
final String text = parent.getItemAtPosition(i).toString();
Toast.makeText(parent.getContext(), text, Toast.LENGTH_SHORT).show();
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
}
我获得微调器值的功能是在volleyrequest下。我猜那是我的代码错误的地方，但是我真的不知道该放什么，哪里错了。
答案 0 :(得分：0)
那只是
final String gender = spinner.getSelectedItem().toString();
