Body
I try to get string with time (hh:mm:ss) but i get this error: <pre><code> 10-28 12:35:27.682: E/AndroidRuntime(14002): java.lang.NullPointerException </code></pre> I call to this by my main class: <pre><code>private TimeUpdater timeupdater; . . . private Runnable runnable = new Runnable(){ public void run() { datasource = new DataSource(getBaseContext()); datasource.open(); comment = datasource.getComment("1"); data = comment.toString().split(" "); /*for(int i=0;i<11;i++) { dataUpdate[i]=data[i+1]; System.out.println("U " + dataUpdate[i]); System.out.println("D " + data[i+1]); }*/ String a = timeupdater.upTime(dane[5]); System.out.println(a); time.setText(timeupdater.upTime(dane[5])); //for(int i=0;i<12;i++) //System.out.println(dane[i]); handler.postDelayed(this, 1000); } }; </code></pre> inside data[5] is 00:00:00 This is my Time Updater class: <pre><code>public class TimeUpdater { private int hh, mm, ss; private String time; private String shh, smm, sss; public String upTime(String time) { String[] czas = time.split(":"); hh = Integer.parseInt(czas[0]); mm = Integer.parseInt(czas[1]); ss = Integer.parseInt(czas[2]); if(ss<60) ss++; if(ss==60) { ss=0; mm++; } if(mm==60) hh++; if(hh<10) shh = "0"+hh; if(mm<10) smm = "0"+mm; if(ss<10) sss = "0"+ss; this.time = shh + ":" + smm + ":" + sss; System.out.println(time); return this.time; } </code></pre> I need because later i want to do more that calls. I need to know how to create in other class public Strings to change data every second

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
