Android Intent fail

I am making an app with a small form, where clicking will change the activity
In the second activity you should see the data entered and when you click on the button return the same data, so that they are edited
The app works well in sending the data to the second activity
but when returning to edit the data, adding the intent to return the app does not work

Try this out. In the MainActivity define SECOND_ACTIVITY variable as below
Public class MainActivity extends AppCompatActivity {
private static final int SECOND_ACTIVITY = 0;
Update the following line from
Intent regresar = new Intent (Confirmar_Datos.this, MainActivity.class);
to
Intent regresar = new Intent (this, Confirmar_Datos.class);
Replace startActivity(regresar); with
startActivityForResult(regresar, SECOND_ACTIVITY);
In the second activity replace Intent regresar = new Intent (Confirmar_Datos.this, MainActivity.class); with
Intent regresar = new Intent()
Also replace startActivity(regresar); with
setResult(Activity.RESULT_OK,regresar);
finish();
On the first activity the data will be onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent return_data) {
super.onActivityResult(requestCode, resultCode, return_data);
if (requestCode == SECOND_ACTIVITY) {
if(resultCode == Activity.RESULT_OK){
String result=return_data.getStringExtra("key"); // This from regresar.putExtra
}
}
}//onActivityResult

Android Updating Last ListView After Fragment Change

I have 2 different Fragments and in first Fragment, I am adding a new student entry to my custom Student ArrayList. I also have a ListView to show my student list in my second Fragment. However, when I go to my second Fragment, it doesn't update the latest ListView. So my question is that how can I update my ListView after I change my Fragment tab?
registerBtn simply adds a new entry to my studentsArrayList.
At first, I tried to use "Get" button to update my ListView but it didn't work. What I want to do is that refreshing my ListView whenever I pass to my StudentsFragment.

"Troubleshooting
If calling notifyDataSetChanged() doesn't work all the layout methods won't help either. Believe me the ListView was properly updated. If you fail to find the difference you need to check where the data in your adapter comes from.
If this is just a collection you're keeping in memory check that you actually deleted from or added the item(s) to the collection before calling the notifyDataSetChanged().
If you're working with a database or service backend you'll have to call the method to retrieve the information again (or manipulate the in memory data) before calling the notifyDataSetChanged().
The thing is this notifyDataSetChanged only works if the dataset has changed. So that is the place to look if you don't find changes coming through. Debug if needed."

Clear variable when Android back button is clicked

I have an app where I would like to be able to click on a button, A, and show a certain set of information. Then click the back button and click on button B and show a different set of information. I have coded a test TextView into the Drinks.java file in order to begin the process by confirming what is being passed along. Currently whatever button I push first is getting stuck in the variable. So for example if I push button A, then push the back arrow and push button B, button A is still showing up in the textView. I tried making the Strings empty within the on click listener, to "clear them out" as it were, but that isn't working. Is there a way to wipe out what is in the variable and reassign something else? Or does my problem lie elsewhere?

You are properly not able to send values between different activities, i will give you an example, try it.
The syntax is like this
For sending data
String data = getIntent().getExtras().getString("keyName");
Intent intent = new Intent(ActivityOne.this, ActivityTwo.class);
intent.putExtra("keyName","value");
For receiving at ActivityTwo
String value= getIntent().getStringExtra("keyName");
Intent intent = getIntent();
Bundle extras = intent.getExtras();
Additional hint:-
So you need to edit in FirstActivity
btn_Cal21.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(SecondMarks_1.this,FirstResult.class);
Bundle b = new Bundle();
b.putInt("res1",Total21);
b.putString("per1",f21);
i.putExtras(b);
startActivity(i);
finish();
}
});
Same for the following activities.
Still Did not get ? Actually in you FirstActivity you have put
Intent i = new Intent(FirstMarks.this,FirstResult.class);
Bundle b = new Bundle();
b.putInt("res1",Total1);
b.putString("per1",f1);
And in your second activity.
Intent i = new Intent(SecondMarks_1.this,FirstResult.class);
Bundle b = new Bundle();
b.putInt("res1",Total21);
b.putString("per1",f21);
i.putExtras(b);
startActivity(i);
You see you have used per1 string in both places, change that, that is probably causing the app not to get values(possibly give some other string).
And in this part, you need to add code for 2nd activity result to be received.
Bundle b = getIntent().getExtras();
sres1 = b.getInt("res1", 0);
sper1 = b.getString("per1");
Hope that helps.

android crash when trying to get extras.getLong

I have been trying for hours to figure out why android crashes after loading Profile activity. The line that is causing the issue is :
mRowId = extras != null ? extras.getLong(OverLimitDbAdapter.KEY_ROWID): null;
located in Profile.java. so I have firstly
OvertheLimit.java which puts extras via a menu option intent:
package uk.co.obdesign.android.overthelimit;
import android.app.Activity;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.RadioButton;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;
import android.widget.Toast;
public class Overthelimit extends ListActivity {
private OverLimitDbAdapter dbHelper;
private static final int USER_CREATE = 0;
private static final int USER_EDIT = 1;
private Cursor cursor;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.getListView();
dbHelper = new OverLimitDbAdapter(this);
dbHelper.open();
fillData();
registerForContextMenu(getListView());
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
fillData();
}
private void fillData() {
cursor = dbHelper.fetchAllUserDrinks();
startManagingCursor(cursor);
String[] from = new String[] { OverLimitDbAdapter.KEY_USERNAME };
int[] to = new int[] { R.id.label };
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter notes = new SimpleCursorAdapter(this,
R.layout.user_row, cursor, from, to);
setListAdapter(notes);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.profile:
Intent myIntent1 = new Intent(Overthelimit.this, Profile.class);
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID, cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
startActivityForResult(myIntent1, 0);
return true;
case R.id.myusual:
Intent myIntent2 = new Intent(Overthelimit.this, MyUsual.class);
startActivityForResult(myIntent2, 0);
return true;
case R.id.trackme:
Intent myIntent3 = new Intent(Overthelimit.this, TrackMe.class);
startActivityForResult(myIntent3, 0);
return true;
case R.id.moreinfo:
Intent myIntent4 = new Intent(Overthelimit.this, MoreInfo.class);
startActivityForResult(myIntent4, 0);
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onDestroy() {
super.onDestroy();
if (dbHelper != null) {
dbHelper.close();
}
}
}
then selecting the profile menu option takes me to Profile, which crashes trying to get extras.
I have checked data using toast and it's there. any ideas?

Your problem is most likely that you add a String extra (as cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)) returns a String) - but try to get a Long extra - which does not compute.
The following should fix the problem:
mRowId = extras != null ? Long.parseLong( extras.getString(OverLimitDbAdapter.KEY_ROWID) ) : null;

In your Overthelimit class you set the value with the following line:
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID, cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
This puts a String value into the intent extras. Trying to get the same value as a Long value will make you applications crash, as it does not exist as a Long value. If you instead convert the value you get from your cursor object (or gets it directly as a Long from your cursor), your application should not crash anymore. Alternatively, you can get your value from the intent extras by using getString(), not getLong().

I think it giving type casting error as you store the value as string in put try to type cast at putting the value time or get the as string and then convert to long value but for type casting may be you getting type casting error in this so put into the try catch block and see the logcat details to detecting the error
type cast here from string to long or
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID,cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
or get as string here and then type cast from string to long
String s = extras.getString(OverLimitDbAdapter.KEY_ROWID);
mRowId = extras != null ? Long.parseLong(s): null;
