Hello Everyone,

I don't know if this is the right place for this but I am trying to get some constructive criticism for my programming style and I made my first usefull...ish script.

I used to love fortune and I would always add it to .bashrc so I would get a cool greeting. However I am pretty sure I have memorized all of them and I wanted to make something similar for the new Unix world.

So I used my new ruby skills and made a script that downloads a random inspirational quote and displays it to standard output.

If any one is interested they can download it and give it try from https://github.com/tyrel86/Inspiring-Quotes

There are instructions on how to get it up and running please let me know what you think.

Please note you will need a ruby interpreter for it to work as well as ruby gems and the colorize gem.

Thank you every one

I hope its alright to make a new thread but the problem is different.
Alright I have been working on a chess clock of epic proportions and
almost have it up and running. But for the last and coolest part of
its functionality I have hit a wall and would appreciate some help.
The story so far:
The DatabaseHelper class can successfully add rows to the data base
which happens in an activity called add precept. I have pulled the db
file off the device and viewed it with SQLite viewer and all is well.
When I try to load one of the rows and use the data for the main
activities state things begin to go astray.
I have a method in the main activity called setClocks its a wrapper
class that uses the DatabaseHelper method getEntry to fill a MyObject
which has all the data I need to set the apps state. Please help me
figure out why a call of setClocks(1); results in an exception no row
found.
Here is the code:
//The wrapper class in the main activity public void setClocks(long index) { MyObject data; dbh.open(); data = dbh.getEntry(index); if( data.handiState == "white" ) { ctBlack.SetTime(data.timeInMills); ctWhite.SetTime(data.timeInMills + data.handiTimeInMills); } else if( data.handiState == "black" ) { ctWhite.SetTime(data.timeInMills); ctBlack.SetTime(data.timeInMills + data.handiTimeInMills); } else if ( data.handiState == "none" ) { ctBlack.SetTime(data.timeInMills); ctWhite.SetTime(data.timeInMills); } isFisher = Boolean.parseBoolean(data.isFisher); fisherTimeInMills = data.fisherTimeInMills; dbh.close(); } //The DatabaseHelper method public MyObject getEntry(long _rowIndex) throws SQLException { Cursor cursor = db.query(true, DATABASE_TABLE, null, KEY_ID + "=" + _rowIndex, null, null, null, null, null); if ((cursor.getCount() == 0) || !cursor.moveToFirst()) { throw new SQLException("No to do item found for row: " + _rowIndex); } MyObject entry = new MyObject(); entry.name = cursor.getString(cursor.getColumnIndex(KEY_NAME)); entry.timeInMills = cursor.getLong(cursor.getColumnIndex(KEY_TIM)); entry.handiTimeInMills = cursor.getLong(cursor.getColumnIndex(KEY_HTIM)); entry.fisherTimeInMills = cursor.getLong(cursor.getColumnIndex(KEY_FTIM)); entry.handiState = cursor.getString(cursor.getColumnIndex(KEY_HCS)); entry.isFisher = cursor.getString(cursor.getColumnIndex(KEY_IF)); return entry; } //Definition of my object public class MyObject { public String name; public long timeInMills; public long fisherTimeInMills; public long handiTimeInMills; public String isFisher; public String handiState; }
If I call setClocks(1); in the onCreate of the main activity the app
crashes with the could not find row exception. I know their is a row
with an _id of 1 I can see it on my desktop. I want to load the first
precet when the app loads and then in the onCreateOptionsMenu I have
an option to select a preset. When this is selected it displays a
dialog with a spinner and 2 buttons one for loading the selected
preset and one for removing the selected preset from the database.
Here is my attempt at that. It loads the dialog and the dialog is
populated by the database but when I press load it just goes back to
the main activity with the timers as they where.
public boolean onOptionsItemSelected(MenuItem item) { switch( item.getItemId() ) { case R.id.Menu_LoadPreff: final Dialog dialog = new Dialog(this); dialog.setTitle("Pick a precet"); dialog.setCancelable(true); dialog.setContentView(R.layout.precetselector); final Spinner spinner = (Spinner) dialog.findViewById(R.id.SpinPrecet); dbh.open(); Cursor select = dbh.getAllEntries(); SimpleCursorAdapter myAdapt = new SimpleCursorAdapter(dialog.getContext(), android.R.layout.two_line_list_item, select, new String[] {DatabaseHelper.KEY_NAME, DatabaseHelper.KEY_ID,}, new int[] {android.R.id.text1}); spinner.setAdapter(myAdapt); dialog.show(); Button load, delete; load = (Button) dialog.findViewById(R.id.PrecetLoad); delete = (Button) dialog.findViewById(R.id.PrecetDelete); load.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { setClocks(spinner.getSelectedItemPosition()+1); dialog.dismiss(); dbh.close(); } }); break;
And if you need it the setTime method for a ChessClock an inner class
of the main Activity which has its own inner class CountDownTimer
public void SetTime(long millisInFuture) { timer = new Timer( millisInFuture, 1000); //Timer is the inner CountDownTimer tv.setText(formatTime(millisInFuture)); //tv is the linked text view length = millisInFuture; //length is used for the reset button or when one player looses and the activity starts over }
Thank you for reading hope all is well.

Alright I got the spinner working
final Dialog dialog = new Dialog(this); dialog.setTitle("Pick a precet"); dialog.setCancelable(true); dialog.setContentView(R.layout.precetselector); final Spinner spinner = (Spinner) dialog.findViewById(R.id.SpinPrecet); dbh.open(); Cursor select = dbh.getAllEntries(); SimpleCursorAdapter myAdapt = new SimpleCursorAdapter(dialog.getContext(), android.R.layout.two_line_list_item, select, new String[] {DatabaseHelper.KEY_NAME, DatabaseHelper.KEY_ID,}, new int[] {android.R.id.text1}); spinner.setAdapter(myAdapt); dialog.show(); Button load, delete; load = (Button) dialog.findViewById(R.id.PrecetLoad); delete = (Button) dialog.findViewById(R.id.PrecetDelete);

In case you need the log cat:

So I am making an app that has user created precepts. In the on create options menu their is an option to create the precept which loads a new activity with some forums then an apply button that writes the forums to a data base. I know this part works because I have read the data with an SQLite browser after pulling the file off the emulator. There is another option to load one of the precepts and this is where I am having issues. I am trying to populate a spinner with all of the rows of the Data Base and display it in a dialog. With the code as it is now it displays the dialog but the dialog has a spinner within a spinner its very strange. If you select the inner spinner it displays a blank spinner and if you select the outer spinner it crashes.

so here is the code in the activity class where I try and make the dialog:

case R.id.Menu_LoadPreff: dbh.open(); Cursor cursor = null; try { cursor = dbh.getAllEntries(); } catch(Exception e) { Log.e("while trying to obtain cursor", e.toString()); } cursor.moveToFirst(); startManagingCursor(cursor); Dialog dialog = new Dialog(this); dialog.setTitle("Pick a precet"); dialog.setCancelable(true); dialog.setContentView(R.layout.precetselector); Spinner spinner = (Spinner) dialog.findViewById(R.id.SpinPrecet); SimpleCursorAdapter sca = new SimpleCursorAdapter(this, R.layout.precetselector, cursor, new String[] {DatabaseHelper.KEY_ID,DatabaseHelper.KEY_NAME}, new int[] {android.R.id.text1}); sca.setDropDownViewResource(R.id.SpinPrecet); spinner.setAdapter(sca); dialog.show(); break;

Here is the DatabaseHelper classes getallEntries() method:

public Cursor getAllEntries () { return db.query(DATABASE_TABLE, new String[] {KEY_ID, KEY_NAME}, null, null, null, null, null); }

And finally the precetselector.xml file
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <Spinner android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_width="fill_parent" android:id="@+id/SpinPrecet" android:layout_centerHorizontal="true" android:layout_centerVertical="true"> </Spinner> </RelativeLayout>

Any help would be greatly appreciated this is the last thing I need to acomplish to feel good about realsing my first app the the Market.
Thank you thank you thank you

Does any one know how to make text upside down in android? I am working on a chess clock and would like to make the text for the top user readable by him. I already have the XML set up exactly how I want it so If its possible to keep my XML file for the rest of the content view I would greatly appreciate that method. Thank you every one.

So I was running updates while working on a project in eclipse. I should have looked but I didn't and eclipse was being updated as well. Then eclipse started acting very glitchy so I reinstalled it. I went then to reinstall the DDMS and android developer tools but eclipse said they were already installed. Cool so I went to make a new android project but my only options were the project templates that come with eclipse. So I uninstalled and reinstalled the DDMS and Developer tools but this did not help either. I am very lost if any one can help me I am completely out of ideas. Thank you.

When you do scanner.nextInt and you type in a value then hit the enter key so the input gets flushed to the scanner. My guess is the nextInt method is consuming the integer but not the new line. Then the next time you try to consume a line it gets the new line character still left in the buffer from when you entered the integer. Try consuming the nextLine one prior to the for loop.

That was exactly what happened thank you to all that helped. Here is the working code:
import java.util.*; public class JibberTalk { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); ArrayList<String> jibbers = new ArrayList<String>(); System.out.print("How many times shall I jibber oh great one: "); int whereIsThatJibber = scanner.nextInt(); scanner.nextLine(); //This is what fixed it for(int i = 0; i < whereIsThatJibber; i++) { System.out.println("Please enter a Jibber oh great one: "); String addAJibber = scanner.nextLine(); jibbers.add(addAJibber); } System.out.println("You have " + jibbers.size() + " jibbers"); System.out.println("Now I do a little jibber jabber ju and: "); while(!(jibbers.isEmpty())) { int removeAJibber = (int) (Math.random() * jibbers.size()); System.out.println("Jibber: " + jibbers.get(removeAJibber)); jibbers.remove(removeAJibber); } } }

First off just signed up and I love the moose and the agreement...be nice right on I think I am in the right place.

I have recently started learning java in anticipation of developing for android. I was making a program that would ask the user how many lines they wanted to jibber jabber then take that many lines of input and add it to an array list. Then randomly go through and print those strings back. My code works except one little glitch which I don't under stand. On the first pass of the for loop where it take the user input and adds it to the ArrayList it just displays the System.out.print(); but does not get the user input then on the second and all passes thereafter it works the way I wanted it to. Any insights would be very appreciated.

Here is the code its just one class and all in main. I know its bad practice but I am not planning on reusing my Jibber Jabber lol:
import java.util.*; public class JibberTalk { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); ArrayList<String> jibbers = new ArrayList<String>(); System.out.print("How many times shall I jibber oh great one: "); int whereIsThatJibber = scanner.nextInt(); for(int i = 0; i < whereIsThatJibber; i++) { System.out.print("Please enter a Jibber oh great one: "); String addAJibber = scanner.nextLine(); jibbers.add(addAJibber); } System.out.println("You have " + jibbers.size() + " jibbers"); System.out.println("Now I do a little jibber jabber ju and: "); while(!(jibbers.isEmpty())) { int removeAJibber = (int) (Math.random() * jibbers.size()); System.out.println("Jibber: " + jibbers.get(removeAJibber)); jibbers.remove(removeAJibber); } } }
Also let me know if there is some way I am suposed to display code I am new to this forum.
