I have a school project on shoe sticker and trying to figure out on how to do it based on the codes on github
The problem I’m facing with is, it is not able to display currentNearableInfo when the sticker is picked up( motion detected) it is only able to display when I manually clicked on the sticker icon. Is it possible that you provide me some guidance to where I have made my mistake or point out where should I make changes.
public class ListNearablesActivity extends BaseActivity {
private static final String TAG = ListNearablesActivity.class.getSimpleName();
public static final String EXTRAS_TARGET_ACTIVITY = "extra sTargetActivity";
public static final String EXTRAS_NEARABLE = "extrasNearable";
private static final int REQUEST_ENABLE_BT = 1234;
private BeaconManager beaconManager;
private NearableListAdapter adapter;
@Override protected int getLayoutResId() {
return R.layout.main;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Configure device list
adapter = new NearableListAdapter(this);
ListView list = (ListView) findViewById(R.id.device_list);
list.setAdapter(adapter);
list.setOnItemClickListener(createOnItemClickListener());
//Initialize Beacon Manager
beaconManager = new BeaconManager(this);
}

private AdapterView.OnItemClickListener createOnItemClickListener() {
return new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY) != null) {
try {
Class<?> clazz = Class.forName(getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY));
Intent intent = new Intent(ListNearablesActivity.this, clazz);
intent.putExtra(EXTRAS_NEARABLE, adapter.getItem(position));
startActivity(intent);
} catch (ClassNotFoundException e) {
Log.e(TAG, "Finding class by name failed", e);
}
}
}
};
}
How about:
@Override public void onNearablesDiscovered(List nearables) {
for (Nearable nearable : nearables) {
if (nearable.identifier.equals("54b128ebbc420d35") && nearable.isMoving) {
// stop scanning to prevent duplicate "clicks"
beaconManager.stopNearableDiscovery(scanId);
// do whatever you'd ordinarily do in the onClick listener here
// ...
}
}
}
Hi:
I want to have the onclick button and with sticker when it is moving then perform an action. How do I have the 2 condition
private AdapterView.OnItemClickListener createOnItemClickListener() {
return new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY) != null) {
try {
Class<?> clazz = Class.forName(getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY));
Intent intent = new Intent(ListNearablesActivity.this, clazz);
intent.putExtra(EXTRAS_NEARABLE, adapter.getItem(position));
startActivity(intent);
} catch (ClassNotFoundException e) {
Log.e(TAG, "Finding class by name failed", e);
}
}
}
};
Just set up the Nearables scanning the way it’s described in the Quick Start:
… then, use the implementation of the onNearablesDiscovered I’ve posted above, and replace the identifier (it’s the 54b128ebbc420d35 string) of the sticker which you want to trigger the “click” to one of your own.
Finally, replace the “do whatever you’d ordinarily do in the onClick listener here” with your onItemClick code:
if (getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY) != null) {
try {
Class<?> clazz = Class.forName(getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY));
Intent intent = new Intent(ListNearablesActivity.this, clazz);
intent.putExtra(EXTRAS_NEARABLE, adapter.getItem(position));
startActivity(intent);
} catch (ClassNotFoundException e) {
Log.e(TAG, "Finding class by name failed", e);
}
}
Hi heypiotr,
After I did this, I got plenty of errors 
beaconManager.setNearableListener(new BeaconManager.NearableListener() {
@Override
public void onNearablesDiscovered(List<Nearable> nearables) {
for (Nearable nearable : nearables) {
if (nearable.identifier.equals("065473d63cd9d687") && nearable.isMoving) {
private AdapterView.OnItemClickListener createOnItemClickListener() {
return new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY) != null) {
try {
Class<?> clazz = Class.forName(getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY));
Intent intent = new Intent(ListNearablesActivity.this, clazz);
intent.putExtra(EXTRAS_NEARABLE, adapter.getItem(position));
startActivity(intent);
} catch (ClassNotFoundException e) {
Log.e(TAG, "Finding class by name failed", e);
}
}
}
};
}
}
}
}
}
You pasted in too much. Use the exact snippet from my previous post.
Hi heypiotr,
If I use the above exact snippet form the previous post, I can only have one condition which is detect motion to display the information, and I’m not able to click to display the information
beaconManager.setNearableListener(new BeaconManager.NearableListener(){
@Override public void onNearablesDiscovered (List nearables){
for (Nearable nearable : nearables) {
if (nearable.identifier.equals(“065473d63cd9d687”) && nearable.isMoving) {
// stop scanning to prevent duplicate "clicks"
beaconManager.stopNearableDiscovery(scanId);
// do whatever you’d ordinarily do in the onClick listener here
// …
if (getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY) != null) {
try {
Class<?> clazz = Class.forName(getIntent().getStringExtra(EXTRAS_TARGET_ACTIVITY));
Intent intent = new Intent(ListNearablesActivity.this, clazz);
intent.putExtra(EXTRAS_NEARABLE, adapter.getItem(position));
startActivity(intent);
} catch (ClassNotFoundException e) {
Log.e(TAG, “Finding class by name failed”, e);
}
}
}
}
}
});
Errors:
beaconManager.setNearableListener - cannot resolve symbol ‘setNearableListener’
@Override - ‘@Override’ is not applicable to local variable
public void onNearablesDiscovered - variable ‘onNearablesDiscovered’ is never used
List - expression expected
List nearables - cannot resolve symbol ‘nearables’
{ - ; expected
adapter.getItem(position) - cannot resolve symbol position
Hi @heypiotr,
What I have done now is when 1st click on sticker then 2nd upon detect motion it then will display the CurrentNearableInfo() but I want 2 condition either click on the sticker or detect motion to display CurrentNearableInfo().
Also another problem is when I click sticker A, and when sticker B in motion, it will display information of Sticker A. Can you help me with it

Hi @heypiotr,
did you see my last reply ?
Yes, sorry for the wait. I’ll get back to you with an example later this week.
