Ok - So I'm really lost at this point...
I have an xml layout where a user can input several settings. My goal is to be able to save these settings and retrieve them at a later date - which I've done successfully up until this point. I have sqlite database which stores several values including the currentHour from the timepicker as well as another xml layout which outputs the settings saved in the database.
Currently - the timePicker only saves the currentHour to the database and then to the string I'm using to display it in the view_country XML file.
What I'd like to do is display the entire time - not just the currentHour (ex. currentHour : currentMinute in order to display the full time 4:00AM) as a string I can use to display the time in another xml layout.
P.S.
I really need a straightforward answer on how this can be done (just assume I know nothing) I've been trying to accomplish this for several days and I still need assistance getting the currentMinute displayed next to my currentHour.
I've made several attempts at this however at this time I feel its best to revert back to my last known working state (I've been getting force close issues when attempting different methods of concatenating the two fields) and ask for help. (I know it can't be TOO hard to store and display a time value from a TimePicker - especially for some of you more skilled StackOverflow ninjas)

You can add the minutes by keeping one column in the database and one string. Then you must split the time string, when setting the TimePicker
String time = extras.getString("time");
String[] parts = time.split(":");
timeEt.setCurrentHour(Integer.valueOf(parts[0]));
timeEt.setCurrentMinute(Integer.valueOf(parts[1]));
and concat it, when inserting or updating
dbConnector.insertContact(nameEt.getText().toString(),
capEt.getText().toString(),
timeEt.getCurrentHour().toString() + ":"
+ timeEt.getCurrentMinute().toString(),
codeEt.getText().toString());
Or keep a separate hour and minute. This means extending the database schema and DatabaseConnector to cope for an additional parameter, but avoids splitting the string, when you need the parts.

I have a void method synchronizeNum(String String String) Which will be trigger in onViewCreated , This Line.
new DisDepartmentSender(myView.getContext(), urlAddress, accountEmail, departmentName).execute();
It will get data from database and finally pass back and set the data into this method synchronizeNum (String String String).After i set the data i wish to display it using TextView. I think the only way is execute again onViewCreated method, since we cannot setText inside synchronizeNum method.I have tried many detach and attach method inside the method but the problem is it get NullPointer i donno how to solve i have been looking around for 1 day just for this little problem. I need you guys help please.

I recommend to create an interface for updating data.
public interface SynchronizeCallback {
void synchronizeNum(String num1room1, String num2room2, String num3room3);
}
Your fragment should implement this interface.
Also set the text to the TextViews inside synchronizeNum():
num_1.setText(num1);
num_2.setText(num1);
num_3.setText(num1);
room_1.setText(room1);
room_2.setText(room2);
room_3.setText(room3);
Pass the interface to your task when you create it:
new DisDepartmentSender(myView.getContext(), urlAddress, accountEmail, departmentName, this).execute();
In onPostExecute of your AsyncTask call
syncronizeCallback.updateValues(newNum1room1, newNum2room2, newNum3room3);
Then you should see the new data.
This Java takes the inputs of Edit Text fields and outputs them into Toast.
I have no idea where or what the error is, any help would be greatly appreciated:

For whatever reason, when the submit button is clicked, the program stops in the emulator. The error in the Android Monitor states: "java.lang.IllegalStateException: Could not find method btnSubmit(View) in a parent or ancestor Context for android:onClick attribute defined on view class android.support.v7.widget.AppCompatButton with id 'button'"
As I see you have 2 Button but I dont know which one is submit button.
well also I can not find the meaning of public void btnSubmit(). As I know you should define tn submit:
Button btnSubmit = (Button) findViewById(R.id.your_btnSubmit_id);
and then use onClickListener method to do somthing when btn clicked
btnsubmit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Do somthing
}
});
Edit:
You can use your code just replace
public void btnSubmit()
with this:
public void btnSubmit(View v)
I am trying to retrieve value from the database and am using EditText to display in the android application. But the project is stopped whenever I try to retrieve it. I am using eclipse to develop the android project.

I'm going to assume that this line's the cause of your problem:
EditText editText3=(EditText)findViewById(R.id.xray);
Your activity_select.xml doesn't define a control with the ID xray hence the call to findViewById returns a null and your call to editText3.setText() results in an NPE. It does, however, have TextViews with IDs XRay and xRay. Try using one of those instead.
I have some XML which should be displaying the hour from TimePicker data but every time I try to view the data it force closes. I've narrowed the issue down to an incorrect setup in my XML file(s) but I can't seem to correct the issue and keep the app from force closing.

UI element "#+id/timeEdit" defined in layout view_country.xml is a TextView. You are tring to cast it to android.widget.TimePicker in your activity ViewCountry.
There is another UI element with same id ("#+id/timeEdit") which indeed IS TimePicker but it's placed in layout for AddEditCountry activity.
Check your ViewCountry layout and code, probably element #+id/timeEdit shouldn't be a TextView, or you should cast it to TextView in your onCreate method.
This is the error i get. You can see all the codes that are affected by this session below. Where i put the intent, where i get it, the classes and paremeters involved.

This is where i put the extras
package kfc.project;

import android.widget.Toast;
public class ProductListView extends ListActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final ProductList pl = new ProductList();
//setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, PRODUCTS));
setListAdapter(new ArrayAdapter<Product>(this, R.layout.list_item, pl.getList() ));

}
});
}
//TEST STRING ARRAY
static String[] PRODUCTS = new String[] {
"Chicken", "Rice", "Coke", "Chicken Burger"
};
}
This is where the array list items are added
package kfc.project;
import java.util.ArrayList;
public class ProductList {
ArrayList<Product> list;
public ProductList (){
list = new ArrayList<Product>();
//CREATE PRODUCT HERE
Product chicken;
list.add(new Product("ChickenTest",99));
Product rice;
list.add(new Product("RiceTest",11));
}
public String[] getNames (){
int c = 0;
int size = list.size() - 1;
String[] names = new String[size];
while (size >= c) {
//names.add(list.get(c).getName());
names[c] = list.get(c).getName();
c++;
}
c = 0;
return names;
}
public ArrayList<Product> getList (){
return list;
}
}
This is the code for the parameteres
package kfc.project;
public class Product {
String name;
int servingSize;
int calories;
int fat;
int saturatedFat;
int transFat;
int cholesterol;
int sodium;
int carbs;
int protein;
public Product (String name, int servingSize, int calories, int fat, int saturatedFat, int transFat, int cholesterol, int sodium, int carbs, int protein){
this.name=name;
this.calories=calories;
this.servingSize=servingSize;
this.fat=fat;
this.saturatedFat=saturatedFat;
this.transFat=transFat;
this.cholesterol=cholesterol;
this.sodium=sodium;
this.carbs=carbs;
this.protein=protein;
}
public Product (String name, int servingSize){
this.name=name;
this.servingSize=servingSize;
}
public String getName() {
return name;
}
public int getServingSize() {
return servingSize;
}
public int getCalories() {
return calories;
}
public int getFat() {
return fat;
}
public int getSaturatedFat() {
return saturatedFat;
}
public int getTransFat() {
return transFat;
}
public int getCholesterol() {
return cholesterol;
}
public int getSodium() {
return sodium;
}
public int getCarbs() {
return carbs;
}
public int getProtein() {
return protein;
}
}
the extras variable is NULL
Bundle extras = getIntent().getExtras();
String name = extras.getString("name");
Update:
First, this line is not needed
startActivity(new Intent("kfc.project.PRODUCTDETAIL"));
Second, you need to getExtra() from getIntent() in productdetail, not getExtras().
For sample:
// get intent object once
Intent receivedIntent = getIntent();
// get product name
String productName = receivedIntent.getExtra("name");
// get serving size
int servingSize = receivedIntent.getExtra("serving size");
// do the same for other props
Bundle extras = getIntent().getExtras();
String name = extras.getString("name");
getExtras() may return null if there are no extras stored in the intent. Check the extras for null.
You might need to do a null check for the extras.
Just remove this line
startActivity(new Intent("kfc.project.PRODUCTDETAIL"));
It starts your activity without extra, causing your extras to be null
