Make the SearchView do searches

Question

I have a SearchView up and ready, here is the code I use in the java file of the page that has the SearchView:

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.options_menu, menu);

        // Associate searchable configuration with the SearchView
        SearchManager searchManager =
                (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView =
                (SearchView) menu.findItem(R.id.search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(
                new ComponentName(getApplicationContext(), SearchableActivity.class)));


        return true;
    }

My goal is now to let this SearchView search through a site full of TextViews. Every TextView contains one word. Is it possible to make the SearchView find the TextView that contains the word i just typed in? If so, how? If not, how can I make it happen in another way?

Kind regards, Julian

The SearchView doesn't do any search at all, it's a simple widget for inputting the keywords, show recently used keywords, etc. You should implement your "search model" to find the content, and display it somewhere you want.

My bad because of asking the question wrong I guess. So I have everything set up to this point, the next step I have to take is to define Querys or something like that or a virtual table, but I feel like thats not what I am looking for if I want to search for TextViews. So basically the question is, if I should create a virtual table for my goal. – user7342339 Dec 28 '16 at 10:55
@user7342339 What do you mean by "search for TextViews"? search the text shown in `TextView` widget? If that's really what you want (instead of search in a model like e.g. a sqlite db), you can use `TextView.getText()` to get the content for each text view widget. – xizzhu Dec 28 '16 at 10:57
I have around 40 TextViews that all contain one word. What I wanna do is, to search for the words inside the TextViews, but I am not sure how to tell the SearchViews and everything that is linked to that, what I want to find. – user7342339 Dec 28 '16 at 11:03
40 TextViews were stored in somewhere maybe in list or map or array you have to search there abt the keyword. – Maveňツ Dec 28 '16 at 11:04
So I have to set up an Array in order to make the textViews "searchable"? – user7342339 Dec 28 '16 at 11:07

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.menu_search));
        SearchManager searchManager = (SearchManager) getSystemService(Activity.SEARCH_SERVICE);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

// Setting up custom search button icon
        int searchImgId = android.support.v7.appcompat.R.id.search_button; // I used the explicit layout ID of searchview's ImageView
        ImageView v = (ImageView) searchView.findViewById(searchImgId);
        v.setImageResource(R.drawable.ic_search_black);
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                // Do operation
                return true;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                return false;
            }
        });

        return true;
    }

menu_search.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:appcompat="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/menu_search"
        style="@android:style/Widget.ActionButton"
        android:icon="@drawable/ic_search_black"

It says, that it cannot resolve method getActivty(), am I making a rookie mistake? :D – user7342339 Dec 28 '16 at 11:06
getActivity() can be replaced by your context friend... try **getApplicationContext()** or pass **context** instead of getActivity() if your code is in activity then, remove **getActivity().** if you are using fragment than try solution mentioned as above. – Deep Patel Dec 28 '16 at 11:09
I see, and what is the goal of the last line? Because (menu, inflate) is also marked red, as onCreateOptionsMenu cannot be applied to androidViewMenuInflate. Thanks for the help btw! – user7342339 Dec 28 '16 at 11:13
are you using this code for activity or a fragment? can you tell me? so that i can help you accordingly – Deep Patel Dec 28 '16 at 11:14
I am using this code as a method inside the acitivity with the TextViews that should be searched through. So I guess it's for activity, isn't it? – user7342339 Dec 28 '16 at 11:18
naah! its for fragment, let me update the code for activity... check the answer now – Deep Patel Dec 28 '16 at 11:20
let me know if it works.. BTW i m sure it will work :) – Deep Patel Dec 28 '16 at 11:24
This looks pretty good, thank you! Two more questions though, what do I have to put in line 4 instead of menu_search? ^^ – user7342339 Dec 28 '16 at 11:29
Check updated answer now....create a menu file under the folder res > menu > menu_search.xml – Deep Patel Dec 28 '16 at 11:34
SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.menu_search)); This line is giving me a NullPointerExeption now, I feel like I have to learn a lot :D – user7342339 Dec 28 '16 at 11:42
Please check the menu_search.xml file is correctly under , res > menu > menu_search.xml. you can check if its correctly placed or not by ctrl + click on that menu_search in line which it gives error. – Deep Patel Dec 28 '16 at 11:45
Yes it is, there is also a file called options_menu.xml which I created yesterday similar to the menu_search.xml file. Is it possible that this is the problem? Do you need some kind of data, like the error code or something? – user7342339 Dec 28 '16 at 11:50
if both are similar files having similar ids, you can change id for one of the file. Or you can remove one file and use same file for all occurrences – Deep Patel Dec 28 '16 at 11:52
Ok, that is not the problem. I will find a way to fix it later for sure, just another question real quick; in the public boolean onQueryTextSubmit method, what kind of operation do I put in there? Or do you know any keywords I can search for on the web? Thank you so much again! – user7342339 Dec 28 '16 at 11:59
in that operation part, if you have a list of content than by using loop you can compare the content with the content written in the searchview. **query** will return value in searchview and you can search from your existing bunch of data by that – Deep Patel Dec 28 '16 at 12:07

I guess what you are trying to do is search through text inside TextViews defined inside your layout. I am assuming here that the text source is a String Array/ArrayList (TextViewData) in a file "Data.java.

You can give this a try:

1) Make the activity/fragment implement SearchView.OnQueryTextListener

2) Create an empty ArrayList to store search entry results.

private ArrayList<Data> mSearchItems

3) Add this line to the code where you initialize your SearchView

searchView.setOnQueryTextListener(this);

4) Override the following methods:

i) Method called on submit:

    @Override
    public boolean onQueryTextSubmit(String query) {
    //Call a user defined mathod to handle the search.
    handleSearch(query, Data.TextViewData)
}

ii) Method called on changing the text in the search box

@Override
public boolean onQueryTextChange(String query) {
    handleSearch(query, Data.TextViewData)
}

5)

private void handleSearch(String Query, ArrayList<Data> queryList){
mSearchItems.clear();
for(Data data  : queryList){
    if(data.textviewone.toLowerCase().contains(Query.toLowerCase()) ||
    data.textviewtwo.toLowerCase().contains(Query.toLowerCase()))
    mSearchItems.add(data);
    //You can then swap the recycler view (if being used) or hide other text views and display only the one being searched for (in case of a match)
   }
}

Example: If you have a TextView with id textviewone and ArrayList textData. And you wanna display "My name is userxyz" in the TextView. You can add the text to the list like: textData.add("My name is userxyz"); and display it inside the textView as: TextView txt = (TextView) findViewById(R.id.textviewone); txt.setText(textData.get(0)); — Suhayl SH, Dec 28 '16 at 11:39
I see, and then the search will find the text inside the ArrayList and then show the TextView that is bound to the the searched text? Thank you btw! — user7342339, Dec 28 '16 at 11:43
You are welcome :).. If my answer helped, do give a thumbs up! — Suhayl SH, Dec 28 '16 at 11:44
