Question

I have this code:

entryData = new Entry[] { 
        new Entry( path1, name1, tag1 ),
        new Entry( path2, name2, tag2 ),
        new Entry( path3, name3, tag3 ),
        new Entry( path4, name4, tag4 )
};

The data above gives my list view 4 items (rows). That works fine.

But if I loop, for example:

for(x=0; x<4; x++){
    entryData = new Entry[] { new Entry( pathx, namex, tagx ) };
}

My list view shows one item (row) only…

My class code is:

public class Entry {
    public String icon;
    public String title;
    public String tag;

    public Entry() {
        super();
    }

    public Entry(String icon, String title, String tag) {
        super();
        this.icon = icon;
        this.title = title;
        this.tag = tag;
    }
}

Any ideas? I’m just learning it again! TIA!!!

The array must be defined before the loop. Each iteration should only add an element to the array:

entryData = new Entry[4];
for (int i = 0; i < 4; i++){
    entryData[i] = new Entry(pathx, namex, tagx);
}

If you don’t know the size of the array in advance, then use a List instead, which grows dynamically:

List<Entry> entryData = new ArrayList<Entry>();
// ...
for (int i = 0; i < someDynamicValue; i++) {
    entryData.add(new Entry(pathx, namex, tagx));
}

Also, please respect the Java naming conventions.
