So I have an app that has tabs (4) that each have their own layout and class files. I also have a searchview widget in the actionbar.
What I am attempting to do is allow the user to search for something, get that as a string and then send it to the fragment so I can then use that string and update the UI after using it for a query.
Currently I have it so that the user enters in the text, a class handles the intent and so on a so forth, and then I get that variable in the fragment class that I need it in.
However, when I enter in something to the searchview and hit enter, a new window pops up but with a blank screen. No tabs. No searchview.
Surely I am doing something wrong. Does anyone have an suggestions or a change that I can make?
MainActivity.java
public class MainActivity extends FragmentActivity implements ActionBar.TabListener
{
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Home", "Most Recent", "Followed", "All Items" };

mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs)
{
actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
}
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position)
{
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);

setIntent(intent);

}
private void handleIntent(Intent intent)
{
if(Intent.ACTION_SEARCH.equals(intent.getAction()))
query = intent.getStringExtra(SearchManager.QUERY);
}
}
companyFragment.java
public class companyFragment extends Fragment
{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View rootView = inflater.inflate(R.layout.company, container, false);
String temp = new SearchResultsActivity().query;
TextView tv = (TextView) rootView.findViewById(R.id.textView1);
tv.setText(temp);
return rootView;
}
}
I implemented a basic search example awhile back.
Hopefully this should put you in the right direction.

I have a MainActivity and Three Fragments with recyclerViews inside the three fragments, the recyclerview contain two textviews, i want the user to click on the recyclerview and the text in should be passed on to the new activity, i am a little bit new so i would appreciate it if you can give me detailed code and some explanation.
I want to click on an item in the recyclerview and that should open a new activity, data(text) should be passed from the recyclerview to the new activity.

Create an interface
public interface OnHymnClickListener {
void onHymnClick(HymnModel hymnModel);
}
Pass the listener to the adapter
public class RVAdapter extends RecyclerView.Adapter<ItemViewHolder> {
private OnHymnClickListener listener;
public void setListener(OnHymnClickListener listener) {
this.listener = listener;
}
#Override
public void onBindViewHolder(ItemViewHolder itemViewHolder, int i) {
final HymnModel model = mCountryModel.get(i);
itemViewHolder.bind(model);
itemViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(listener != null) {
listener.onHymnClick(model);
}
}
});
}
}
Let your fragment implement it
public class TabOneFragment extends Fragment implements SearchView.OnQueryTextListener, OnHymnClickListener {
#Override
public void onHymnClick(HymnModel hymnModel) {
//put data to bundle and startActivity
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
adapter = new RVAdapter(mHymnModel);
adapter.setListener(this);
recyclerview.setAdapter(adapter);
}
}
Hello first of all you always want to start your activity from activity or fragment.
Never start it from adapter.
So in your adapter constructor add this
public AdapterName(......,Context context){
...your code.
this.mContext=context;
}
pass context there.
and than inside this method
public ItemViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(mContext instanceof YourActivityName){
((YourActivityName)mContext).yourDesiredMethod();
}
}
});
I developed an android application, as you see in this picture,
I used sherlock action bar for searching, the only problem is that when the user search something in web tab if he/she wants to see the image result, he should type and search again in image tab, is there any way to pass the edittext parameter to other tabs and do searching when user changed the tabs?
MainActivity:
public class MainActivity extends SherlockFragmentActivity implements
TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private com.actionbarsherlock.app.ActionBar actionBar;
private String[] tabs = { "Sound", "Image", "Web" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getSupportActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
actionBar.setHomeButtonEnabled(false);
viewPager.setAdapter(mAdapter);
viewPager.setOffscreenPageLimit(3);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.addTab(actionBar.newTab().setText(tabs[0])
.setTabListener(this), false);
actionBar.addTab(actionBar.newTab().setText(tabs[1])
.setTabListener(this), false);
actionBar.addTab(actionBar.newTab().setText(tabs[2])
.setTabListener(this), true);
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabSelected(com.actionbarsherlock.app.ActionBar.Tab tab,
android.support.v4.app.FragmentTransaction ft) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(com.actionbarsherlock.app.ActionBar.Tab tab,
android.support.v4.app.FragmentTransaction ft) {
}
#Override
public void onTabReselected(com.actionbarsherlock.app.ActionBar.Tab tab,
android.support.v4.app.FragmentTransaction ft) {
}
}
Adapter:
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
return new Sound();
case 1:
return new Image();
case 2:
return new Search();
}
return null;
}
#Override
public int getCount() {
return 3;
}
}
Sound Frgment:
public class Sound extends Fragment {
private String URL_ADDRESS, Servlet;
private ListView listview;
private ListViewAdapter adapter;
private List<Spanned> numberlist = new ArrayList<Spanned>();
private List<Ava2> avaList = new ArrayList<Ava2>();
private Boolean isInternetPresent = false;
private ConnectionDetector detector;
private View rootView;
private RelativeLayout loading, layout;
private int counter = 10;
private EditText editText;
private String a = "http://***";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.ava, container, false);
ImageButton voiceSearch = (ImageButton) rootView
.findViewById(R.id.imageButton2);
ImageButton buttonSearch = (ImageButton) rootView
.findViewById(R.id.imageButton1);
listview = (ListView) rootView.findViewById(R.id.listview);
loading = (RelativeLayout) rootView.findViewById(R.id.loading);
layout = (RelativeLayout) rootView.findViewById(R.id.layout);
editText = (EditText) rootView.findViewById(R.id.editText1);
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId,
KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_SEARCH) {
search();
return true;
}
return false;
}
});
buttonSearch.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
search();
}
});
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view,
int position, long l) {
try {
Intent i = new Intent(getActivity(), Play.class);
startActivity(i);
} catch (Exception e) {
}
}
}
});
return rootView;
}
First,you could write a interface:
public interface OnProfileDataPass {
public String getCurrentSearchword();
public void setCurrentSearchword(String searchword);
}
Then in your fragments:
public class WebFragment extends Fragment {
private OnProfileDataPass dataPasser;
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
dataPasser = (OnProfileDataPass) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString() + " must implement OnProfileDataPass");
}
searchword = dataPasser.getCurrentSearchword();
}
}
In your activity:
public class MainActivity implements OnProfileDataPass {
String currentSearchword;
#Override
public String getCurrentSearchword() {
return currentSearchword;
}
#Override
public String setCurrentSearchword(String searchword) {
this.currentSearchword = searchword;
}
}
That's my solution.When you change the tap,you could listen the proper event and set the word with getActivity.setCurrentSearchword(String newword),then you could get the newword in the fragment's dataPasser variable's method getCurrentSearchword() to get the search word. I have test it in my app. Wish that helps you a little.
you should save the value of the editText in your activity and then pass it as an argument when you call your fragment, using the same technique as the one described here: http://developer.android.com/reference/android/app/Fragment.html
I have one SherlockFragmentActivity with 3 fragments. Everything works fine but when I swipe from fragment to fragment, wrong menus are shown. Fragment1 is showing menu from fragment2, SearchView on Fragment1 is filtering data on Fragment2. Here is the code for SherlockFragmentActivity
public class MainHolder extends SherlockFragmentActivity {
private static final String[] CONTENT = new String[] { "FRAGMENT1", "FRAGMENT2", "FRAGMENT3" };
FragmentAdapter mAdapter;
ViewPager mPager;
TabPageIndicator mIndicator;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_holder);
mAdapter = new FragmentAdapter(getSupportFragmentManager());
mPager = (ViewPager)findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mIndicator = (TabPageIndicator)findViewById(R.id.indicator);
mIndicator.setViewPager(mPager);
}
class FragmentAdapter extends FragmentPagerAdapter {
public FragmentAdapter(FragmentManager fm) {
super(fm);
}
public Fragment getItem(int position) {
switch(position)
{
case 0:
return Fragment1.newInstance(CONTENT[position % CONTENT.length]);
case 1:
return Fragment2.newInstance(CONTENT[position % CONTENT.length]);
case 2:
return Fragment3.newInstance(CONTENT[position % CONTENT.length]);
default:
return null;
}
}
#Override
public CharSequence getPageTitle(int position) {
return CONTENT[position % CONTENT.length].toUpperCase();
}
#Override
public int getCount() {
return CONTENT.length;
}
}
#Override
public void onBackPressed() {
Fragment fragment = (Fragment) getSupportFragmentManager().findFragmentByTag("android:switcher:" + R.id.pager + ":"+mPager.getCurrentItem());
if (fragment != null) // could be null if not instantiated yet
{
if (fragment.getView() != null) {
// Pop the backstack on the ChildManager if there is any. If not, close this activity as normal.
if (!fragment.getChildFragmentManager().popBackStackImmediate()) {
finish();
}
}
}
}
}
And here is for the fragment
public class Fragment1 extends SherlockFragment {
private static final String KEY_CONTENT = "Fragment1:Content";
LazyAdapter fragment1adapter;
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear();
inflater.inflate(R.menu.fragment1, menu);
MenuItem searchItem = menu.findItem(R.id.menu_search);
final SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setQueryHint("Pretraga ...");
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextChange(String newText) {
if (newText.length() != 0) {
fragment1adapter.getFilter().filter(newText);
return true;
}
return false;
}
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
});
searchView.setOnCloseListener(new SearchView.OnCloseListener() {
#Override
public boolean onClose() {
fragment1adapter.getFilter().filter("");
return false;
}
});
}
public static Fragment1 newInstance(String content) {
Fragment1 fragment = new Fragment1();
StringBuilder builder = new StringBuilder();
for (int i = 0; i < 20; i++) {
builder.append(content).append(" ");
}
builder.deleteCharAt(builder.length() - 1);
fragment.mContent = builder.toString();
return fragment;
}
private String mContent = "???";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if ((savedInstanceState != null) && savedInstanceState.containsKey(KEY_CONTENT)) {
mContent = savedInstanceState.getString(KEY_CONTENT);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment1, container, false);
setRetainInstance(true);
setHasOptionsMenu(true);
setMenuVisibility(true);
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putString(KEY_CONTENT, mContent);
}
}
Other fragments are the same, with their separate menus and layouts. Can anyone give me some hints why is this happening?
The solution is to remove setMenuVisibility(true); from fragments onCreateView.
I'm having a strange problem using an ActionView in my Actionbar (specifically ActionbarSherlock). This issue is only happening in devices below SDK 3.0 (basically Gingerbread devices is all I'm testing on).
My app has a ViewPager and I am animating one of my menu items while an AsyncTask is running. If I touch the ActionView before swiping everything is ok, if I swipe to any of the views, then go back to the first view, which is the only view to have the ActionView, and touch the ActionView the icon is doubling up on itself, like so:
I had this same issue previously, before I implemented a ViewPager, and I fixed it by stopping and starting the animation in onCreateOptionsMenu and calling invalidateMenuOptions, which is why I have ActivityCompat.invalidateOptionsMenu(this); in onResume of the Activity. I was hoping, by calling that, the menu would refresh itself and fix the duplicating, but it isn't.
UPDATE Using getSherlock().dispatchInvalidateOptionsMenu(); seems to, at least, get the menu to refresh itself, but it causing the ActionView to go nuts.
ViewPager:
public class Main extends SherlockFragmentActivity
{
private static List<Integer> mIds;
private static SparseArray<Fragment> mPageReferenceMap = new SparseArray<Fragment>();
#Override
public void onCreate(final Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.main);
mViewPager = (ViewPager)findViewById(R.id.viewpager);
mMyFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager());
mViewPager.setAdapter(mMyFragmentPagerAdapter);
mViewPager.setOnPageChangeListener(new OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
GetListingFragment().StopAnimation(); //needed to add this because the ActionView was showing on the other views when swiping
}
#Override
public void onPageScrolled(int position, float offset, int offsetPixel) {
}
#Override
public void onPageScrollStateChanged(int state) {
}
});
mIds = new ArrayList<Integer>();
mIds.add(0);
mIds.add(1);
mIds.add(2);
}
#Override
public void onResume()
{
super.onResume();
ActivityCompat.invalidateOptionsMenu(this);
}
private ListingFragment GetKeywordsFragment()
{
ListingFragment lf = (ListingFragment)getSupportFragmentManager().findFragmentById(R.id.fragmentListing);
if (lf == null)
{
final MyFragmentPagerAdapter fpa = (MyFragmentPagerAdapter)mViewPager.getAdapter();
lf = (ListingFragment)fpa.getFragment(0);
}
return lf;
}
private static class MyFragmentPagerAdapter extends FragmentStatePagerAdapter {
public MyFragmentPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
if (index == 0)
{
final ListingFragment lf = ListingFragment.newInstance();
mPageReferenceMap.put(index, lf);
return lf;
}
else
{
final DetailFragment df = DetailFragment.newInstance(mIds.get(index));
mPageReferenceMap.put(index, df);
return df;
}
}
public Fragment getFragment(int key) {
return mPageReferenceMap.get(key);
}
#Override
public int getCount() {
return 3;
}
}
}
Fragment:
public class ListFragment extends SherlockListFragment
{
private int mId;
private MenuItem refreshItem;
private AsyncTask<Void, String, Void> gi;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
public static ListingFragment newInstance(int id) {
ListingFragment lf = new ListingFragment();
Bundle bundle = new Bundle();
bundle.putInt("id", id);
lf.setArguments(bundle);
return lf;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (getArguments() != null)
mId = getArguments().getInt("id");
return inflater.inflate(R.layout.listing, container, false);
}
private class GetItems extends AsyncTask<Void, String, Void> {
#Override
protected void onPreExecute()
{
StartAnimation();
}
#Override
protected Void doInBackground(Void... unused)
{
//background process to get items
}
protected void onPostExecute(final Void unused)
{
StopAnimation();
}
}
#Override
public void onCreateOptionsMenu(final Menu menu, final MenuInflater inflater) {
inflater.inflate(R.menu.keyword_menu, menu);
StopAnimation();
refreshItem = menu.findItem(R.id.refresh);
if (fi != null && fi.getStatus() == AsyncTask.Status.RUNNING)
StartAnimation();
super.onCreateOptionsMenu(menu, inflater);
}
private void StartAnimation() {
if (refreshItem != null && refreshItem.getActionView() == null)
{
final LayoutInflater inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final ImageView ivRefresh = (ImageView)inflater.inflate(R.layout.refresh_view, null);
final Animation rotation = AnimationUtils.loadAnimation(activity, R.anim.refresh);
ivRefresh.startAnimation(rotation);
refreshItem.setActionView(ivRefresh);
}
}
public void StopAnimation()
{
if (refreshItem != null && refreshItem.getActionView() != null)
{
refreshItem.getActionView().clearAnimation();
refreshItem.setActionView(null);
}
}
#Override
public boolean onOptionsItemSelected(final MenuItem item)
{
if (item.getItemId() == R.id.getitems) {
gi = new GetItems(getActivity(), null);
return true;
} else {
return super.onOptionsItemSelected(item);
}
}
}
Looks like this is a known bug in ABS:
