So i found this perfect code to be able to select zip from sd, but the list looks so basic and I would like to add icons (like one common icon for all dirs), however it seems too hard to do on my own, here is the code:
Code:
private void loadFileList(File path) {
this.currentPath = path;
List<String> r = new ArrayList<String>();
if (path.exists()) {
if (path.getParentFile() != null) r.add(PARENT_DIR);
FilenameFilter filter = new FilenameFilter() {
@SuppressLint("DefaultLocale")
public boolean accept(File dir, String filename) {
File sel = new File(dir, filename);
if (!sel.canRead()) return false;
if (selectDirectoryOption) return sel.isDirectory();
else {
boolean endsWith = fileEndsWith != null ? filename.toLowerCase().endsWith(fileEndsWith) : true;
return endsWith || sel.isDirectory();
}
}
};
String[] fileList1 = path.list(filter);
for (String file : fileList1) {
r.add(file);
}
}
fileList = (String[]) r.toArray(new String[]{});
}

and fw-res.apk..
iam almost making a tut for it...will add it in my tut thread soon..
I am developing an application which draws the path of the user as he moves and calculates the area .
This is the code i am trying my problem is at the start of recording the path the path is drawn even if the user has not moved and sometimes when even if user is moving the path is not drawn .
RouteOverlay class:
public class RouteOverlay extends Overlay {
private GeoPoint gp1;
private GeoPoint gp2;
private int mode = 1;
public RouteOverlay(GeoPoint paramGeoPoint1, GeoPoint paramGeoPoint2,int paramInt)

this.gp1 = paramGeoPoint1;
this.gp2 = paramGeoPoint2;
this.mode = paramInt;
}
public void draw(Canvas paramCanvas, MapView paramMapView,

mPaint.setStrokeCap(Paint.Cap.ROUND);
mPaint.setStrokeWidth(3);
mPaint.setAlpha(120);
Point p1 = new Point();
Point p2 = new Point();
Path path = new Path();
projection.toPixels(gp1, p1);
projection.toPixels(gp2, p2);
path.moveTo(p2.x,p2.y);
path.lineTo(p1.x,p1.y);
paramCanvas.drawPath(path, mPaint);
}

/*if (lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
gpsstatus.setText("Gps Is Enabled");
}else

}
This probably has to do with the accuracy of the GPS. I didn't really look at your code but maybe you should add some kind of buffer. if (movement>5m){//draw stuff}
Hi,
I searched for a part to ask questions abut android programing but cant find so I posted here,I hope I can find my answer
I am new with android programing and I have a problem with expandable list view
I pupulate my data to an expandable list view with SimpleExpandableListAdapter and every thing is good..The only think I want is to findout which Items is selected by user..I searched but Cant fine a working method to do this
here Is my SimpleExpandableListAdapter
Code:
SimpleExpandableListAdapter expListAdapter =
new SimpleExpandableListAdapter(
this,
groupData,
android.R.layout.simple_expandable_list_item_1,
new String[] { "grup"},
new int[] { android.R.id.text1 },
childData,
R.layout.database_list_item,
new String[] { parser.KEY_CatName, parser.KEY_PoetID, parser.KEY_DownloadUrl,parser.KEY_PubDate,parser.KEY_FileSizeInByte,"Status"},
new int[] { R.id.chk_database_list_item,R.id.txt_database_poet_id,R.id.txt_database_download_link,R.id.txt_database_pub_date,R.id.txt_database_size,R.id.txt_database_status }
);
and here Is setOnChildClickListener but It dont do anything
Code:
ExpandList.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView arg0, View v, int arg2,
int arg3, long arg4) {
Log.i("setOnChildClickListener", "setOnChildClickListener");
TextView down_link = (TextView) v.findViewById(R.id.txt_database_download_link);
TextView poet_id = (TextView) v.findViewById(R.id.txt_database_poet_id);
String down_linkString;
String poet_idString;
SparseBooleanArray choices = arg0.getCheckedItemPositions();
StringBuilder choicesString = new StringBuilder();
for (int i = 0; i < choices.size(); i++)
{
//added if statement to check for true. The SparseBooleanArray
//seems to maintain the keys for the checked items, but it sets
//the value to false. Adding a boolean check returns the correct result.
//ArrayList<String> Items_for_download = new ArrayList<String>();
if(choices.valueAt(i) == true)
choicesString.append(poet_id.getText().toString()).append(" ");
}
Log.i("selected", choicesString.toString());
return false;
}
});
Thanks for your helps
I'm new to android,stuck in this part of my code.
I do hope, someone would help me with it.
As ,I've stuck for quite a while and have to complete within 2 days,

Hi,
I am developing an android app in which i am using csv file and displaying column contents as listview its displaying as [a,b,c,d] in single row how to display them in individual row in listview.Please any one help me how to achive this.
This is my csv file reading code using hashcode.
Code:
public static Map<String,ArrayList<String>> parseCsv(InputStreamReader reader, String separator, boolean hasHeader) throws IOException {
Map<String,ArrayList<String> > values = new LinkedHashMap<String,ArrayList<String>>();
List<String> columnNames = new LinkedList<String>();
BufferedReader br = null;
br = new BufferedReader(reader);
String line;
int numLines = 0;
while ((line = br.readLine()) != null) {
//if (StringUtils.isNotBlank(line)) {
//if (!line.startsWith("#")) {
String[] tokens = line.split(separator);
if (tokens != null) {
for (int i = 0; i < tokens.length; ++i) {
if (numLines == 0) {
columnNames.add(hasHeader ? tokens[i] : ("row_"+i));
} else {
ArrayList<String> column = values.get(columnNames.get(i));
if (column == null) {
column = new ArrayList<String>();
}
column.add(tokens[i]);
values.put(columnNames.get(i), column);
}
}
}
++numLines;
}
// }//
// }//
return values;
listview code is:
Code:
oslist.add(values);
ListView list = (ListView) findViewById(R.id.studentnames);
String name="name";
// Add it listview
ListAdapter adapter = new SimpleAdapter(this,
oslist, R.layout.student_list, new String[] { name }, new int[] { R.id.name});
list.setAdapter(adapter);
