Sum timestamps from two textviews and display in new textview

I have two textviews and two buttons. When you click on the first button, a window with a choice of time opens. You select the time and it is displayed in textview1. Similarly with the second button and textview2. Now the main task is to sum this time and when you click on the Sum button, display the sum of the time in TextView3 (textview1 + textview2). any ideas how to implement this? preferably with code

long sum = date1.getTime() + date2.getTime();
String date3 = timeFormat.format(new Date(sum));
Log.e("TAG", "Date sum is => " + date3);
**Output: ** Date sum is => 01:05:52

i've tried, how can i fix it ? anyone please help me. thanks.

Anyone else having similar problem. It appears the order in the XML matters too.
I had my NavigationView and after it I had a layout included and I couldn't click an item on the NavigationView.
After I switched them, so that my layout was being included AND THEN AFTER IT I had my NavigationView, it worked ...

this adapter.java
public class Adapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<DataModel> item;
public Adapter(Activity activity, List<DataModel> item) {
this.activity = activity;
this.item = item;
}
#Override
public int getCount() {
return item.size();
}
#Override
public Object getItem(int location) {
return item.get(location);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_buddies, null);
TextView txt_nama = (TextView) convertView.findViewById(R.id.custom_list_item_text1);
txt_nama.setText(item.get(position).getNama());
return convertView;
}
}

You need to create this type of your layout xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" android:id="#+id/drawer_layout"
android:layout_width="match_parent" android:layout_height="match_parent"
android:fitsSystemWindows="true" tools:openDrawer="start">
<FrameLayout
android:id="#+id/container"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
</FrameLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_menu_bar"
app:menu="#menu/activity_menu_bar_drawer" />
</android.support.v4.widget.DrawerLayout>
In FrameLayout you need to replace all fragment one by one like
private void callFragment(Fragment fragment) {
fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
}
Note: You can write your Coordinator layout and other in fragment itself, may be helpful for you.

I don't know what I am doing wrong. I need to get access to those EditText in order to user them and add the user to the SQLite DB but, as the EditText are in the Fragment, I cannot access them directly from the RegisterUser class.
Any ideas on how to solve this? I shall be really and deeply thankful.
Thanks in advance.

Try doing like this,
TextInputLayout FlayoutBirthday= (TextInputLayout) v.findViewById(R.id.flayout_birthday);
EditText i_lname = FlayoutBirthday.getEditText();

Can someone who uses android studio tell me what to do?

My app shuts down when clicking a button, anyone knows why? And if you fins any errors please tell me ;)This activity is about two buttons that when pressed show a TimePickerDialog and save the time.
Here's my code:

Toast.makeText(Main2Activity.this, hour_x + ": " + minute_x, Toast.LENGTH_LONG).show();
}
};

Thanks for your help !!!!

Register listener with your Button after initialize it.
botoFlexio.setOnClickListener(this);
botoAbdominals.setOnClickListener(this);

You need to set listeners to the ImageButtons.
For example:
#Override
protected void onCreate(Bundle savedInstanceState) {
....
botoFlexio.setOnClickListener(this);
botoAbdominals.setOnClickListener(this);
}

How do i make list of items and amounts with an add item button that displays a new item with a button click?

I have created the start of an item/amount list with EditText fields but would like it so the total sits directly under the amount and for every new item/amount I add, they would sit just underneath the item/amount above them and the total would then jump down to sit under the newest amount field.
