This may be simple but i couldn't find solution for this. The problem
is setting the background color for gridview items inside the
onitemlongclicklistener method.
I have two linear layouts, one contains the textview and gridview and
another contains some buttons(I set this layout like the menubar on
top of the screen). I hide the second one from the screen using
setVisibility(View.GONE) and when ever I do itemlongclick on the
gridview item the second one will appear using
setVisibility(View.VISIBLE) at the same time I want to change the
bgcolor of the clicked/selected item.
Everything is working fine but whenever the second layout is visible
and also whenever scrolling the gridview, the clicked/selected bgcolor
is disappear.
I tried so many ways but I couldn't solve this problem. Please have
look on my coding and tell me what I did wrong.
gv.setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, View
strings,
int position, long id) {
final Option o = dir.get(position);
//gv.performItemClick(gv,
position,gv.getItemIdAtPosition(position));
/* if(pos!=-1)
{
gv.getChildAt(pos).setBackgroundColor(0xffffffff);
}*/
strings.setSelected(true);
// TextView
tx=(TextView)strings.findViewById(R.id.grid_item_label);
// tx.findViewById(id).setBackgroundColor(0xff0000ff);
/*if(!o.getData().equalsIgnoreCase("o")){
//gv.getChildAt(position).setSelected(true);
fill(new File(new
File(o.getPath()).getParent()),position);
}*/
/*try
{
gv.getSelectedView().setBackgroundColor(0xffcccccc);
}
catch(Exception e){
Toast.makeText(FffsdActivity.this, "ok
\n"+e,Toast.LENGTH_SHORT).show();
}*/
/*for(int i=0;i<nofifo;i++)
{
try{
if(gv.getChildAt(i).isSelected())
{
gv.getChildAt(i).setBackgroundColor(0xffbbbbbb);
// Toast.makeText(FffsdActivity.this, "yes ok
\n"+i,Toast.LENGTH_SHORT).show();
}
else{
gv.getChildAt(i).setBackgroundColor(0xffffffff);
//Toast.makeText(FffsdActivity.this, "no ok
\n"+i,Toast.LENGTH_SHORT).show();
}
}
catch(Exception e)
{
Toast.makeText(FffsdActivity.this, "i wanna e :"+e
+"\n"+i,Toast.LENGTH_SHORT).show();
}
try{
gv.getChildAt(i).setSelected(false);
//Toast.makeText(FffsdActivity.this, "gv ok
\n"+i,Toast.LENGTH_SHORT).show();
}catch(Exception e){
Toast.makeText(FffsdActivity.this, "i wanna
setselected e :"+e+"\n"+i,Toast.LENGTH_SHORT).show();
}
}*/
// Toast.makeText(FffsdActivity.this, "i wanna
c :"+gv.getChildAt(position).isSelected(),Toast.LENGTH_LONG).show();
//
gv.getSelectedView().setBackgroundColor(0xffcccccc);
pos=position;
if(o.getData().equalsIgnoreCase("parent directory"))
{
fill(new File(o.getPath()),-1);
}
else if(o.getData().equalsIgnoreCase("folder"))
{
llfftools.setVisibility(View.VISIBLE);
TranslateAnimation slide = new TranslateAnimation(0,
0,-llfftools.getHeight(),0 );
slide.setDuration(100);
slide.setFillAfter(true);
llfftools.startAnimation(slide);
//fill(new File(new File(o.getPath()).getParent()));
onFolderClick(o);
//
gv.getChildAt(position).setBackgroundColor(0xffaaaaaa);
}
and my baseadapter is :
public class ImageAdapter extends BaseAdapter {
private Context context;
private final List<Option> mobileValues;
public ImageAdapter(Context context,List<Option> fofivalues) {
this.context = context;
this.mobileValues = fofivalues;
}
public View getView(int position, View convertView, ViewGroup parent)
{
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
//if (convertView == null) {
gridView = new View(context);
// get layout from mobile.xml
gridView = inflater.inflate(R.layout.mobile, null);
/*} else {
gridView = (View) convertView;
}*/
// set value into textview
TextView textView = (TextView)
gridView.findViewById(R.id.grid_item_label);
//to set the max no.of chararcters in textview
String
iname=(mobileValues.get(position).getName().length()>10)?
mobileValues.get(position).getName().substring(0,
9)+"..":mobileValues.get(position).getName();
if(mobileValues.get(position).getPosition()==position&&mobileValues.get(position).getPosition()!
=-1)
{
textView.setText(iname);
textView.setTextColor(0xff0000ff);
}
else{
textView.setText(iname);
}
// set image based on selected text
final ImageView imageView = (ImageView)
gridView.findViewById(R.id.grid_item_image);
/*gridView.setOnLongClickListener(new
OnLongClickListener() {
public boolean onLongClick(View v) {
gridView.setBackgroundColor(0xffaaaaaa);
// TODO Auto-generated method stub
return false;
}
});*/
String mobile = mobileValues.get(position).getData();
if(mobile=="o")
{
//do nothing
imageView.setImageResource(R.drawable.white);
}
else if(mobile=="Parent Directory")
{
imageView.setImageResource(R.drawable.parent);
}
else if (mobile=="Folder")
{
imageView.setImageResource(R.drawable.folderg);
}
else{
imageView.setImageResource(R.drawable.picicon);
}
return gridView;
}
public int getCount() {
return mobileValues.size();
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
}
thanks in advance and if you want anything more please let me know...
