}
try adding this to your activity:
<meta-data
android:name="android.app.default_searchable"
android:value="e.ftsexample.MainActivity" />
Edit: The reason is that you configured your activity to receive search query, but not to initiate a search.you can add this to any other activity and start search by callin
onSearchRequested();
hope this help.

I have a list view that displays all the songs in my device in the application, then when I click on the song another activity opens where you can play the song, on emulator when I click on the song in the list it takes me to the other activity and I can play and hear the song, but on real device I'm not getting any error but when I select an item from the list, I get the name and artist of the song, but when i click on play it doesn't work, I don't hear sound nor can I jump to middle of song etc..
the list is like this:

String path = songCursor.getString(indexData);
songArrayList.add(new Songs(title, artist, path));
}while (songCursor.moveToNext());
}
songsAdapter.notifyDataSetChanged();
}
}
My adapter:
public class SongsAdapter extends ArrayAdapter<Songs> {

Songs song = getItem(position);
tvTitle.setText(song.getTitle());
tvArtist.setText(song.getArtist());
return convertView;
}
}
I have no idea why it's not working, I don't get any error in the logcat, the music just doesn't start, it stays frozen at 0:00, and I cant jump to middle of it etc, although the name and artist name get obtained successfully just no audio

I am trying to implement simple quick settings tile with the help of google docs,
but my tile appears to be there but greyed out(intent activity)- I can't click or do anything with it and cant remove it either without restarting my phone(one plus 3T/oreo8.0.0).
and the same thing goes with sample code google provided.
what things do i need to keep in mind/ how to do it?
is there anything I am missing?
I saw one similar question but it was a bit over my head.

My program is about calculating calories of some food. This is a practice for CS course. I'm beginner on Android OS and I do not know why my receiving process cannot be completed or shown on Activity.
I just write the relevant code pieces here. I had some items on sqlite database and I can check my items on database with Log.d method and they are okay.
App1:
Manifest:
<receiver android:name="ItemBroadcastReceiver"

listView.setAdapter(adapter);

TextView unit = (TextView) view.findViewById(R.id.unit);
unit.setText(" cal");
name.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(1))));
cal.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(2))));
}}
Broadcast Receiver:

You should read about BroadcastReceivers again.
ItemBroadcastReceiver br = new ItemBroadcastReceiver();
Cursor cursor = (Cursor) br.receivedItem;
ReceivedItemsAdapter adapter = new ReceivedItemsAdapter(this, cursor);
ListView listView = getListView();
listView.setAdapter(adapter);
This creates a new instance of the receiver and assigns the receivedItem to cursor. But receivedItem is null and since you never register br for broadcasts, it'll never be not null. Also I'm not sure, if Item could be cast to Cursor.
Considering the code you posted here and the title you used, using BroadcastReceiver might not be a good idea at all. You should try to pass data to Received via intent or load the data directly from persisted storage.
And at last your thread doesn't make any sense.
I have a wearable app that has a couple of fragments created with FragmentGridPagerAdapter. One of the fragments has a couple of CircularButtons and I want to update the backcolor of the button when a message is received from handheld phone. I have no problems in receiving the message. However, button's color (or anything in UI) doesn't update. Do you know how can I fix this?
public class UIPageAdapter extends FragmentGridPagerAdapter {
private final Context mContext;
MainControlFragment[] mainControlFragments;
private List mRows;
uiChangeListener mUIChangeListener = new uiChangeListener();
public UIPageAdapter(Context ctx, FragmentManager fm) {
super(fm);
Log.i("pageAdapter", "constructor");
mContext = ctx;
mainControlFragments = new MainControlFragment[2];
mainControlFragments[0] = new MainControlFragment();
mainControlFragments[1] = new MainControlFragment();
LocalBroadcastManager.getInstance(ctx).registerReceiver(mUIChangeListener,new IntentFilter(Constants.BROADCAST_CONTROL_HOME));
}
#Override
public Fragment getFragment(int row, int col) {
Log.i("PageAdapter","Fragment #" + col +"is asked");
return mainControlFragments[col];
}
public void changeStatus(int button, boolean status) {
mainControlFragments[0].setStatus(button,status);
// notifyDataSetChanged();
}
public class uiChangeListener extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
String act = intent.getAction();
if (act == Constants.BROADCAST_CONTROL_HOME) {
int key = intent.getIntExtra(Constants.CONTROL_HOME_KEY,-1);
String command = intent.getStringExtra(Constants.CONTROL_HOME_COMMAND);
changeStatus(key,command.equals("on"));
}
}
}
#Override
public int getRowCount() {
return 1;
}
#Override
public int getColumnCount(int i) {
return 2;
}
}
Basically when a message received from the handheld device a WearableListener class broadcasts an update message to the UIPageAdapter
This is the listener class
public class ListenerService extends WearableListenerService
{
String tag = "ListenerService";
#Override
public void onMessageReceived(MessageEvent messageEvent) {
final String message = (new String(messageEvent.getData()));
Log.i(tag,message);
LocalBroadcastManager.getInstance(this).sendBroadcast(new Intent(Constants.BROADCAST_CONTROL_HOME)
.putExtra(Constants.CONTROL_HOME_KEY, messageEvent.getPath())
.putExtra(Constants.CONTROL_HOME_COMMAND,Integer.parseInt(message.substring(1)))
.putExtra("caller",tag));
}
#Override
public void onCreate() {
super.onCreate();
Log.i(tag, "onCreate");
}
}

Finally the custom fragment
public class MainControlFragment extends Fragment{
ViewGroup container;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Log.i("controlFragment","create");
this.container = container;
// Inflate the layout for this fragment
return inflater.inflate(R.layout.main_control, container, false);
}
public void setStatus(int button, boolean status) {
Log.i("controlFragment",button + " "+ status);
CircularButton[] btns = new CircularButton[4];
btns[0] = (CircularButton) container.findViewById(R.id.cbtnFront);
btns[1] = (CircularButton) container.findViewById(R.id.cbtnBack);
btns[2] = (CircularButton) container.findViewById(R.id.cbtnBed);
btns[3] = (CircularButton) container.findViewById(R.id.cbtnCoffee);
btns[button].setColor(status?Color.BLACK:Color.RED);
}
}
I also tried the notifyDataSetChanged(); method in UIPageAdapter however it it only calls onCreateView method in fragment. Any help is appreciated
I'm assuming you already resolved this but I had to add a call to invalidate() on the CircularButton after calling setColor():
_circularButton.setColor(ContextCompat.getColor(getActivity(), buttonColor));
_circularButton.invalidate();
Without the call to invalidate the UI only updated some of the time.

but when i combined it with my application it didn't work from the following reason:
In my project i wrote a calling from the main activity to another Fragmentactivity (FBProfile) which is calling the login fragment.
After facebook's authentication it is returned to OnResume in MainActivity instead the overided onActivityresult inside LoginFragment.
I need to create this flow (if its possible):
MainActivity->FBProfile(FragmentActivity)->LoginFragment->Facebook->LoginFragment
The activity that is called by MainActivity:
public class FBProfile extends FragmentActivity{
private LoginFragment loginfragment;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// TODO Auto-generated method stub
Log.i(" Facebook: ", "FBProfile->OnCreate");
if(savedInstanceState==null)
{
loginfragment=new LoginFragment();
getSupportFragmentManager().beginTransaction().add(android.R.id.content, loginfragment).commit();
}
else
{
loginfragment=(LoginFragment) getSupportFragmentManager().findFragmentById(android.R.id.content);
}
}
}
The LoginFragment which is called from FBProfile:
public class LoginFragment extends Fragment {
private View login_view;
private boolean isResumed = false;
private static final String TAG="LoginFragment";
private UiLifecycleHelper uihelper;
private LoginButton authbutton;
private TextView userInfoTextView;
private Session.StatusCallback callback=new Session.StatusCallback() {
#Override
public void call(Session session, SessionState state, Exception exception) {
// TODO Auto-generated method stub
onSessionStatechange(session, state, exception);
}
};
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
Log.i(" Facebook: ", "FBProfile->OnCreate->LoginFragment");
login_view=inflater.inflate(R.layout.profilepage, container,false);
userInfoTextView = (TextView) login_view.findViewById(R.id.userInfoTextView);
authbutton=(LoginButton) login_view.findViewById(R.id.login_button);
authbutton.setFragment(this);
authbutton.setReadPermissions(Arrays.asList("public_profile","email","user_birthday"));
return login_view;
}

private void onSessionStatechange(Session session,SessionState state,Exception exception)
{
if (isResumed) {
if (session != null && session.isOpened()) {
Intent intent = new Intent(getActivity(),
FBProfile.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
if(state.isOpened()){
Log.i(" Facebook: ", "LOGGED IN....");
userInfoTextView.setVisibility(View.VISIBLE);
// Request user data and show the results
Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user, Response response) {
// TODO Auto-generated method stub
if (user != null) {
// Display the parsed user info
userInfoTextView.setText(buildUserInfoDisplay(user));
}
}
});
Toast.makeText(getActivity(), "Logged In", Toast.LENGTH_LONG).show();
}
else
{
userInfoTextView.setVisibility(View.INVISIBLE);
if (Session.getActiveSession() != null) {
Session.getActiveSession().closeAndClearTokenInformation();
}
Session.setActiveSession(null);
Toast.makeText(getActivity(), "Logged Out", Toast.LENGTH_LONG).show();
Log.i(" Facebook: ", "LOGGED OUT....");
}
}

Part of my manifest settings:

Solved. In the Menifast the fragment's father activity was set on nohistory.
I changed it to false and it was solved.
