Issue
I am trying to add a search bar that enables me to search by buttons, search between btn1 and btn2 and btn3. I tried a lot of codes but all of them were focused on TextView and not on buttons. So hope to help me and if I missed details please let me know to describe more.
The two files (.java and .xml) are typed below. thank you.
file.java

@Override

super.onCreate(savedInstanceState);

Button btn1 = findViewById(R.id.btn1);
btn1.setOnClickListener(new View.OnClickListener() {

}});
List<Button> buttonList = new ArrayList<>();
buttonList.add(view.findViewById(R.id.btn1));

sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

buttonList.get(i).setVisibility(View.VISIBLE);
} else {

}
}
return false;
}
@Override

Solution
What do you mean by search by buttons? Are you looking to search the text that is held within the button?
Here is a way you can go about this:
Make a list that contains all the instances of your buttons. List(findViewById(R.id.btn1), etc)
List<Button> buttonList = new ArrayList<>(); buttonList.add(view.findViewById(R.id.button_search1)); buttonList.add(view.findViewById(R.id.button_search2)); buttonList.add(view.findViewById(R.id.button_search3));We are going to use the listeners available to the search view to do the work.
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() { // You can use this for when the submit is clicked @Override public boolean onQueryTextSubmit(String s) { // We loop over the button list for(int i = 0; i < buttonList.size(); i++) { // We get the text of the button String buttonText = (String) buttonList.get(i).getText(); // We turn both the button text and search result to lowercase // So that results are not case sensitive // If they match if(buttonText.toLowerCase(Locale.ROOT).equals(s.toLowerCase())) { // We make button visible buttonList.get(i).setVisibility(View.VISIBLE); } else { // If it doesn't, we make invisible buttonList.get(i).setVisibility(View.INVISIBLE); } } return false; } // You can use this when the text is changing. @Override public boolean onQueryTextChange(String s) { // If text is empty, reset results if(s.isEmpty()) { for(int i = 0; i < buttonList.size(); i++) { buttonList.get(i).setVisibility(View.VISIBLE); } } return false; } });
