我正在制作注册表格，我必须把用户日期并保存在数据库中。我是android的新手，所以我不知道如何将日期选择器放在edittext上并将日期选择器的值发送到server..kindly解决我的问题..
这是我的Registartion.java
public class RegistrationForm extends AppCompatActivity {
EditText fn,ln,mb,em,pw,cpw,dob,gen;
Switch sw;
RadioGroup male,feml;
Switch swth;
private ProgressDialog pDialog;
private static String url_create_book = "http://cloud.....com/broccoli/creatinfo.php";
// JSON Node names
// JSON Node names
private static final String TAG_SUCCESS = "success";
String rval;
JSONParser jsonParser = new JSONParser();
private int serverResponseCode = 0;
Context c;
int i=0;
Button sub;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_registration_form);

sub=(Button)findViewById(R.id.sub2);
sub.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
RadioGroup rgrp=(RadioGroup)findViewById(R.id.rg);
RadioButton radioButton;
int selectedId = rgrp.getCheckedRadioButtonId();
// find the radiobutton by returned id
radioButton = (RadioButton) findViewById(selectedId);
rval=radioButton.getText().toString();
Toast.makeText(RegistrationForm.this,
rval, Toast.LENGTH_SHORT).show();
new CreateNewProduct().execute();
// startActivity(new Intent(RegistrationForm.this, Home.class));
}
});
}
class CreateNewProduct extends AsyncTask<String, String, String> {
private String fname;
private String lname;
private String email;
private String passwrd;
private String cpasswrd;
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(RegistrationForm.this);
pDialog.setMessage("Creating books..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
fname = fn.getText().toString();
lname = ln.getText().toString();
email = em.getText().toString();
passwrd=pw.getText().toString();
cpasswrd=cpw.getText().toString();
}
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("First_Name", fname));
params.add(new BasicNameValuePair("Last_Name",lname));
params.add(new BasicNameValuePair("email", email));
params.add(new BasicNameValuePair("Gender", rval));
params.add(new BasicNameValuePair("password", passwrd));
params.add(new BasicNameValuePair("confirmPasw",cpasswrd));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_book,
"POST", params);
// check log cat fro response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Intent i = new Intent(getApplicationContext(), Login.class);
startActivity(i);
// closing this screen
finish();
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
pDialog.dismiss();
}
}

我不太了解NameValuePair将数据发送到服务器，因为它现在已经取消了... 您可以使用库将数据发送到服务器，该服务器由谷歌名称 VOLLEY LIBRARY
提供使用排球你需要将它添加到你的应用程序leve gradle dependencies
compile 'com.android.volley:volley:1.0.0'
并将数据发送到服务器，就像这种格式......
ProgressDialog progress=new ProgressDialog(mContext, R.style.MyProgressDialog);
progress.setProgressStyle(android.R.style.Widget_ProgressBar_Small);
progress.show();
StringRequest stringRequest = new StringRequest(Request.Method.POST, PROJECT_URL,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
progress.dismiss();
if (response.trim().equals("success")) {
Toast.makeText(mContext, "Project Sucessfully Send", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(mContext, response, Toast.LENGTH_LONG).show();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
progress.dismiss();
Toast.makeText(mContext, error.toString(), Toast.LENGTH_LONG).show();
}
}
) {
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> map = new HashMap<>();
map.put("teacher-email", teacheremail);
map.put("teacher-name", teachername);
map.put("student-id", id);
map.put("student-name",to);
map.put("title",title);
map.put("message", message);
map.put("project-url", project);
map.put("status",status);
map.put("startdate",startdate);
map.put("enddate",enddate);
return map;
}
DATE PICKER
您可以像这样添加日期选择器
Editext et=(Editext)findViewByID(your id);
et.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
int mYear, mMonth, mDay;
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(mContext, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
et.setText(dayOfMonth + "/" + (month + 1) + "/" + year);
}
}, mYear, mMonth, mDay);
//forsetting minimum date for selection
datePickerDialog.getDatePicker().setMinDate(c.getTimeInMillis()); //optional for setting min date
datePickerDialog.show();
}
}
<强>更新
在您的值/样式
上添加此项<style name="datepicker" parent="@android:style/Theme.Holo.Light.Dialog">
<!---TODO-->
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:focusedMonthDateColor">@android:color/holo_red_dark</item>
</style>
并通过更改此
将此主题添加到您的日期选择器DatePickerDialog datePickerDialog = new DatePickerDialog(mContext,R.style.datepicker, new DatePickerDialog.OnDateSetListener()

日期选择器的代码
的xml：
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="date"
android:ems="12"
android:id="@+id/date"
android:focusable="false"
android:textSize="14dp" />
的java：
Calendar myCalendar = Calendar.getInstance();
EditText date = (EditText) findViewById(R.id.date);
final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
String myFormat = "yyyy-MM-dd";
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
date.setText(sdf.format(myCalendar.getTime()));
}
};
date.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new DatePickerDialog(Activity.this, date, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
});
现在要将数据发送到服务器，你的网址就像http://www.domain.com/path/.../creatinfo.php所以要将数据发送到服务器上的那个php文件，使用下面的代码
params.add(new BasicNameValuePair("confirmPasw",cpasswrd));
myCode Goes here
return null;
mycode的：
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.domain.com/path/.../creatinfo.php");
httppost.setEntity(new UrlEncodedFormEntity(params,"UTF-8"));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
InputStream iss = entity.getContent();
} catch(Exception e) {
Log.e("pass 2", "Connection Error");
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader
(new InputStreamReader(iss,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
while ((line = reader.readLine()) != null)
sb.append(line + "\n");
iss.close();
result = sb.toString();
} catch(Exception e) {
e.printStackTrace();
}
try {
JSONObject json_data = new JSONObject(result);
code=(json_data.getInt("code"));
if(code==1){
done = 1; //values saved to database and returned success
}
else
done = 0; //values not saved to database and returned fail
} catch(Exception e) {
e.printStackTrace();
}
