Hi all,
I had an app that was working about 3 years ago that I decided to update for the latest android sdk.I was using tabs but have decided to update to tab fragments with swipe.The problem I'm having is how to lay out the code.I have updated my app but have a few errors.Specifically the Book Now tab usually has a book now form so people can fill it out and upon clicking submit it sms's it to me.Below is the code for BookNowFragmnet.java.
I should mention that the tab and swipe part works flawlessly.I dont have a logcat because it wont build without removing the code

So you are asking for the method "getBaseContext" within an onClickListener... it does not have a method called that... like it's telling you it's undefined
It would probably be a better idea to use application context either by direct use of getApplicationContext or by a "final" reference maybe...

BookNowFragment is not extended from the base type of Context that is expected in the arguments.

Actually the last to are just repeats of the previous really... I'm guessing here but it seems you may have skipped ahead of where you should be in a learning sense.. cause it seems to be like your running without being knowing how to jog kinda thing. Not attempting to be condescending, just I'm a trainer and always attempt to point this stuff out when I see it
Maybe go back and do some of the basics again, and include fragments etc
thanks, Im well aware i'm running before im born but this is the only app I intend to write as it's specifically for my business.

hmmm, well if thats all thats wrong with it, all I could offer is for you to send me the packaged src+res and I will have a look... if it takes less than 20 min to fix and get running I have no problem fixing it for you. If it doesn't and maybe takes longer then I may have to leave it. Should be quick though, up to you
But with the info I gave you should be able to fix those 4 issues...if not hit me up on hangouts and will talk you though it
thanks m8.Ill play around today but if I cant figure it out I might get you to have a look if time permits.I develop in eclipse.Is it a matter of just zipping up the project folder?

Yeah, just zip the project.
But like I say just get a reference to the activity to use as the "context" part of the argument, either where you need it or as a final reference or member variable
so getActivity()
or memberVar
Context mContext = null;
(in onCreate) mContext = getActivity();
or as final
final Context c = getActivity();

I forgot the date and time picker arrrrrrrgh
I've added the following 2 classes which have no errors and seem to function fine.
DatePickerFragment.java
PHP:
package com.test.dfw;
import java.util.Calendar;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.widget.DatePicker;
import android.widget.TextView;
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
TextView txtDate;
public DatePickerFragment(TextView txtDate) {
super();
this.txtDate = txtDate;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
txtDate.setText(new StringBuilder().append(month + 1)
.append("-").append(day).append("-").append(year)
.append(" "));
}
}
TimePickerFragment.java
PHP:
package com.test.dfw;
import java.util.Calendar;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.text.format.DateFormat;
import android.widget.TextView;
import android.widget.TimePicker;
public class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener{
TextView txtTime;
public TimePickerFragment(TextView txtTime) {
super();
this.txtTime = txtTime;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current time as the default values for the picker
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
// Create a new instance of TimePickerDialog and return it
return new TimePickerDialog(getActivity(), this, hour, minute,
DateFormat.is24HourFormat(getActivity()));
}
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
txtTime.setText(hourOfDay+":"+minute);

The problem areas are all under BookNowFragment.java;
1. Under "showCurrentDateOnView" the both findViewById says undefined for the type.I have tried adding rootView but didnt work.
2. Under "showCurrentTimeOnView" both findViewById says undefined for the type.I have tried adding rootView but didnt work.
3. under "showDatePickerDialog" and "showTimePickerDialog" both the getSupportFragmentManager methods show the error "The method getSupportFragmentManager() is undefined for the type BookNowFragment"
4. I also have errors with "onCreateOptionsMenu".I worked out some of them by adding getActivity (see new code below) but it still shows the error "The method onCreateOptionsMenu(Menu) of type BookNowFragment must override or implement a supertype method"
PHP:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getActivity().getMenuInflater().inflate(R.menu.main, menu);
return true;
}
Think there simple issues although I'm simple as well so I could be understating it.

Hey everyone. Here is my code below. I have everything working. Got it to display the pictures and text in a list view. Only issue is that I want to be able to click on one of the list items and have it open an activity. When I added that part in, I get an error that states,
"Error44, 45) error: no suitable constructor found for Intent(<anonymous OnItemClickListener>,Class)
constructor Intent.Intent(String,Uri) is not applicable
(argument mismatch; <anonymous OnItemClickListener> cannot be converted to String)
constructor Intent.Intent(Context,Class<?>) is not applicable
(argument mismatch; <anonymous OnItemClickListener> cannot be converted to Context)"
Here is my code:
Code:
package com.example.matt.nootropicahandbook;
import android.net.Uri;
import android.app.Activity;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
import android.content.Intent;
public class Biohack extends Activity
{
ListView list;
String[] itemname = {"Nootropics", "Supplements", "Metabolic Enhancement","Stacks", "Neuro Stimulation", "Diet", "Stay Away From",};
Integer[] imgid={R.drawable.piracetam1, R.drawable.piracetam2, R.drawable.piracetam3,
R.drawable.piracetam4, R.drawable.piracetam5, R.drawable.piracetam6, R.drawable.piracetam7,};
String[] classNames = {"Main", "Lifehack"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_biohack);
biohacksAdapter adapter=new biohacksAdapter(this, itemname, imgid, classNames);
list=(ListView)findViewById(R.id.list);
list.setAdapter(adapter);
list.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// TODO Auto-generated method stub
String openClass = classNames[position];
try{
Class selected = Class.forName("com.example.matt.nootropicahandbook."+openClass);
Intent selectedIntent = new Intent(this, selected);
startActivity(selectedIntent);
}catch (ClassNotFoundException e)
{
e.printStackTrace();
}
}
});
}
}
The error is on the line:
Code:
Intent selectedIntent = new Intent(this, selected);
And here is my adapter class for refrence
Code:
package com.example.matt.nootropicahandbook;
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class biohacksAdapter extends ArrayAdapter<String>{
private final Activity context;
private final String[] itemname;
private final Integer[] imgid;
private final String[] classNames;
public biohacksAdapter(Activity context,String[] itemname, Integer[] imgid, String[] classNames) {
super(context,R.layout.custom_row, itemname);
this.context = context;
this.itemname = itemname;
this.imgid = imgid;
this.classNames = classNames;
}
public View getView(int position, View view, ViewGroup parent)
{
LayoutInflater inflater = context.getLayoutInflater();
View rowView = inflater.inflate(R.layout.custom_row, null, true);
TextView txtTitle = (TextView) rowView.findViewById(R.id.item);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
TextView extratxt = (TextView) rowView.findViewById(R.id.textView1);
txtTitle.setText(itemname[position]);
imageView.setImageResource(imgid[position]);
extratxt.setText("Description "+itemname[position]);
return rowView;
}
}
replace
Intent selectedIntent = new Intent(this, selected);
to
Intent selectedIntent = new Intent(Biohack.this, selected);
because ...
