i have created a listview contains multiple items, and i added a border to those items so it would look like this:
because of this customized border the original blink of an item get blocked so it doesn't appear, and i've tried to add a blink through animation but there is too much delay and too much work on the main thread, i also used animation inside threads but it is the same with the delay thing, which force me to forget about animation so is there anyway that i can make the item blink when its clicked without using animation or with using it but in an efficient way and by the way i used blink animation inside my onItemClickListener you can find it in the code below:
onItemClickListener that handle the blink:
dataList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, final View arg1,
final int arg2, long arg3) {
// TODO Auto-generated method stub
tvWarningNoEmp.setVisibility(View.GONE);
// adding blink
final Animation animation = new AlphaAnimation(
1, 0); // Change
// alpha
// from
// fully
// visible
// to
// invisible
animation.setDuration(100); // duration - half a
// second
animation
.setInterpolator(new LinearInterpolator()); // do
// not
// alter
// animation
// rate
animation.setRepeatCount(Animation.INFINITE); // Repeat
// animation
// infinitely
animation.setRepeatMode(Animation.REVERSE);
arg1.startAnimation(animation);
// blink one time timer
new CountDownTimer(100, 100) {// CountDownTimer(edittext1.getText()+edittext2.getText())
// also parse it to long
public void onTick(long millisUntilFinished) {
// here you can have your logic to set text to
// edittext
}
public void onFinish() {
arg1.clearAnimation();
}
}.start();
// set margins for tickets buttons
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
params.setMargins(0, 0, 30, 0);
bAssign.setLayoutParams(params);
LinearLayout.LayoutParams paramsO = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
paramsO.setMargins(110, 0, 0, 0);
bEmpChat.setLayoutParams(paramsO);
noEmpLayout.setVisibility(LinearLayout.GONE);
empLayout.setVisibility(LinearLayout.VISIBLE);
Employee item = adapter.getItem(arg2);
ivEmpIcon.setBackgroundResource(R.drawable.free);
tvEmpName.setText(" " + item.getEmpName());
tvEmpDetails.setText(" " + item.getEmpDetails());
empLongitude = item.getEmpLongitude();
empLatitude = item.getEmpLatitude();
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(empLatitude, empLongitude))
.zoom(15).build();
googleEmpMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
MarkerOptions marker = new MarkerOptions().position(
new LatLng(empLatitude, empLongitude)).title(
tvEmpName.getText().toString());
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_RED));
googleEmpMap.addMarker(marker);
// based on item add info to intent
// hide button directions
bEmpDirections.setVisibility(View.GONE);
// current address
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(getApplicationContext(), Locale
.getDefault());
try {
addresses = geocoder.getFromLocation(empLatitude,
empLongitude, 1);
String street = addresses.get(0).getAddressLine(0);
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
tvEmpCurrentAdd.setText(" " + country + "-" + state
+ "-" + street + " st.");
} catch (IOException e) {

If you want a view to blink:
public void blink(final View v) {
v.setBackgroundColor(Color.DKGRAY);
v.animate().setDuration(25).alpha(0).withEndAction(new Runnable() {
@Override
public void run() {
v.setBackgroundResource(R.drawable.standard_key_normal);
v.setAlpha(1);
}
});
}
Send your View to this function, replace the background with whatever drawable or color resource you want. If you want multiple blinks put it in a for loop.

well i figure out how to reduce the delay and add blink effect without using animation and some how it worked for me and there is no more delay, what i did is I've changed the list's linear layouts to relative and that reduced the amount of nested layouts significantly then i added this method:
private void blink(final View v){
final Handler handler = new Handler();
new Thread(new Runnable() {
@Override
public void run() {
int timeToBlink = 1000; //in milissegunds
try{Thread.sleep(timeToBlink);}catch (Exception e) {}
handler.post(new Runnable() {
@Override
public void run() {
if(v == View.VISIBLE){
v.setVisibility(View.INVISIBLE);
}else{
v.setVisibility(View.VISIBLE);
}
blink();
}
});
}
}).start();
then i used it inside onItemClickListener() --> blink(arg1);
worked perfectly for me, also getting the current address was taking too much so i used Async so now there is no delay at all:
Async used as an inner class:
private class LongOperation extends AsyncTask<String, Void, String> {
String all;
@Override
protected String doInBackground(String... params) {
// current address
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(getApplicationContext(), Locale
.getDefault());
try {
addresses = geocoder.getFromLocation(empLatitude,
empLongitude, 1);
String street = addresses.get(0).getAddressLine(0);
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
all="" + country + "-" + state
+ "-" + street + " st.";
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();}
return all;
}
@Override
protected void onPostExecute(String result) {
tvEmpCurrentAdd.setText(all);
}
@Override
protected void onPreExecute() {}
@Override
protected void onProgressUpdate(Void... values) {}
}
and then i called it inside onItemClickListener:
new LongOperation().execute();
hope this will help others that had simillar problem.
