I would like to know if is possible to make the text inside the NumberPicker clickable and to behave the same when I click the white area or the text area. The reason why I try to do such a thing, is that when I have a long string in the bar it becomes really difficult to select that area. I attached my code so far.

Thanks!
The actual solution that I found was to emulate onClick with onTouch, in order to allow the text to be clicked. It works well now.

What i am trying to achieve is when the user taps the list item, the input activity is loaded and the user can update the record. I wasnt able to find an elegant solution other than making an update method in MedicineInputActivity and then getting an instance of MedicineInputActivity in Medicine_Activity and calling update.
I am getting errors like "Attempt to invoke virtual method 'void com.example.shubhmgajra.medikit.MedicineInputActivity.update() on a null object reference".
You can return data from second activity to the first activity when user is done updating the record. You should start second activity by calling startActivityForResult() instead of startActivity() in the first activity. You should also override onActivityResult() in the first activity. You can read more here.
UPDATE:
I think you want to send selected medicine details from Medicine_Activity to MedicineInputActivity. In that case, you can send selected medicine object by binding it to the intent as follows:
public class Medicine_Activity ... {
#Override
protected void onCreate(Bundle savedInstanceState) {
...
listMeds.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
MedicineRecord medicineRecord = db.medicineRecordDao().findMedicineById(id + 1);
Intent intent = new Intent(getApplicationContext(), MedicineInputActivity.class);
intent.putExtra("selectedMedicine", medicineRecord);
startActivity(intent);
MedicineInputActivity.getInstance().update(medicineRecord, true);
}
});
...
}
}
Then on MedicineInputActivity, you should be doing this:
public class MedicineInputActivity ... {
MedicineRecord selectedMedicineRecord;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
selectedMedicineRecord = (MedicineRecord) getIntent().getParcelableExtra("selectedMedicine");
...
}
}
To be able to do this, your MedicineRecord class should implement Parcelable interface.
I've been working on a messaging app and within the group and private chat, the first message duplicates and then when another message is sent, it's hidden behind the duplicated text until another one is sent and then so on. Can anybody help me with this problem? I'm using Quickblox as a database

I am new to android development and I am trying to pass a Boolean value from dialog fragment to the activity.
the boolean value is supposed to be decided by the user(depends on which button user clicked). However, the boolean immediately turned to false without clicking any button.
I have tried various method recommended I found on internet but none of them works for me(I guess I have some part screwed up...), these method include:
-broadcasting
-implementing interface
-intent.putExtra
and below is the code that I have came up with, could anyone help me take a look? Any help is appreciated.

public boolean tryAgainEnabled;
Intent intent = new Intent();
#Override

I am also sorry that I am not the best with English, if any things is not clear or not polite because of my poor English, please kindly let me know. I apologize in advance for any mistakes I have made.
It's because you check the value of tryAgainEnabled exactly right after showing the Dialog. Dialog starts Asynchronously, It means that it starts in diffrent Thread and your current thread doesn't wait for dismissing Dialog, So this line of your code if(losingDialogFragment.tryAgainEnabled){ runs exactly after you show dialog, befor you set value to tryAgainEnabled. Because the default value of boolean is always false, you will get false everytime.
I suggest that use listener for this:
Dialog:
public class LosingDialogFragment extends DialogFragment {
public static final String LOSING_FRAGMENT = "LOSING";
public boolean tryAgainEnabled;
Intent intent = new Intent();
private View.OnClickListener onTryAgainButtonClickLisnter;
private View.OnClickListener onGiveUpButtonClickLisnter;
#Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.fragment_lose, container, false);;
final Button tryAgainButton = (Button)rootView.findViewById(R.id.try_again_button);
tryAgainButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(onTryAgainButtonClickLisnter!=null)
onTryAgainButtonClickLisnter.onClick(v);
}
});
Button giveUpButton =(Button)rootView.findViewById(R.id.give_up_button);
giveUpButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(onGiveUpButtonClickLisnter!=null)
onGiveUpButtonClickLisnter.onClick(v);
}
});
getDialog().setTitle(LOSING_FRAGMENT);
return rootView;
}
public void setOnTryAgainButtonClickLisnter(View.OnClickListener onTryAgainButtonClickLisnter) {
this.onTryAgainButtonClickLisnter = onTryAgainButtonClickLisnter;
}
public void setOnGiveUpButtonClickLisnter(View.OnClickListener onGiveUpButtonClickLisnter) {
this.onGiveUpButtonClickLisnter = onGiveUpButtonClickLisnter;
}
}
In your activity call dialog like this:
LosingDialogFragment losingDialogFragment = new LosingDialogFragment();
losingDialogFragment.setOnTryAgainButtonClickLisnter(new View.OnClickListener() {
#Override
public void onClick(View v) {
tryAgain();
losingDialogFragment.dismiss();
}
});
losingDialogFragment.setOnGiveUpButtonClickLisnter(new View.OnClickListener() {
#Override
public void onClick(View v) {
giveUp();
losingDialogFragment.dismiss();
}
});
losingDialogFragment.show(fragmentManager, "");
Declare public boolean tryAgainEnabled; in your Stage Activity and youd can update that variable using ((Stage)context).tryAgainEnabled.

What I'm trying to accomplish is have my view refresh when someone comes back from the settings and changes their preference. I thought this would work but it is not. Any ideas on how i can accomplish this?

I'd suggest to use startActivityForResult and pass a Bundle if sub-activity (FragmentActivity) has been changed.
1) From your Activity start Preference Activity:
Intent intent = new Intent(this, PreferenceActivity.class);
if (!this.isFinishing())
startActivityForResult(intent, REQUEST_UPDATE);
2) Override onActivityResult
#Override
protected void onActivityResult(int reqCode, int resCode, Intent data) {
super.onActivityResult(reqCode, resCode, data);
Log.d(TAG, "Received Result: " + reqCode + " / " + resCode);
}
3) in Subactivity (PreferenceActivity) monitor which keys have been changed and pass it as a bundle if you like
public class PrefsFragment extends PreferenceFragment implements OnSharedPreferenceChangeListener,
OnPreferenceChangeListener {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences);
}
#Override
public boolean onPreferenceChange(Preference arg0, Object arg1) {
getParent().setResult(MainActivity.RESULT_PREFERENCES_CHANGED); // constant
}
#Override
public void onResume() {
super.onResume();
getPreferenceManager().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
}
#Override
public void onPause() {
getPreferenceManager().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
super.onPause();
}
}

You have to think about what you want your Fragment to be - Fragment or SherlockFragment?
You import this:
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuInflater;
import com.actionbarsherlock.view.MenuItem;
And so, your overrides aren't overrides because Menu & friends are different classes right now than what Fragment needs - they are ActionBarSherlock's classes.
If you extend SherlockFragment instead, your overrides should work, and it is recommended to extend SherlockFragment if you are using ActionBarSherlock (which based on your tags, you are).
If you want to keep this as a regular fragment, then import:
android.view.Menu
android.view.MenuItem
android.view.MenuInflater
