How do I capture SearchView's clear button click?

问题

How can I capture the event of user click on clear SearchView text by clicking on the X button on the right

I already captured onQueryTextChange event but, this is for any text change not for that X button

回答1:

After trying a lot of combinations, I found how to capture the event behind the X button in SearchView

Below is a code snippet from onCreateOptionsMenu function in one of my apps. mSearchMenu and mSearchView are global variables. The X is actually an ImageView with ID search_close_btn and the text area is an EditText view with ID search_src_text

@SuppressLint("NewApi")
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu items for use in the action bar
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.country_list_activity_actions, menu);
        mSearchMenu = menu.findItem(R.id.action_search);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            // Get the SearchView and set the searchable configuration
            SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
            mSearchView = (SearchView) menu.findItem(R.id.action_search).getActionView();

            // Assumes current activity is the searchable activity
            mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
            mSearchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default

            // Get the search close button image view
            ImageView closeButton = (ImageView)mSearchView.findViewById(R.id.search_close_btn);

            // Set on click listener
            closeButton.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    LoggerUtils.d(LOG, "Search close button clicked");
                    //Find EditText view
                    EditText et = (EditText) findViewById(R.id.search_src_text);

                    //Clear the text from EditText view
                    et.setText("");

                    //Clear query
                    mSearchView.setQuery("", false);
                    //Collapse the action view
                    mSearchView.onActionViewCollapsed();
                    //Collapse the search widget
                    mSearchMenu.collapseActionView();
                }
            });
        }

        // When using the support library, the setOnActionExpandListener() method is
        // static and accepts the MenuItem object as an argument
        mSearchMenu.setOnActionExpandListener(new OnActionExpandListener() {

            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                //Nothing to do here
                LoggerUtils.d(LOG, "Search widget expand ");
                return true; // Return true to expand action view
            }

            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                LoggerUtils.d(LOG, "Search widget colapsed ");
                return true; // Return true to collapse action view
            }
        });

        return super.onCreateOptionsMenu(menu);
    }

回答2:

you can just use the onCloseListener()

sv= (SearchView) findViewById(R.id.searchView1);

sv.setOnCloseListener(new OnCloseListener() {
            @Override
            public boolean onClose() {
                Toast t = Toast.makeText(MainActivity.this, "close", Toast.LENGTH_SHORT);
                t.show();

                return false;
            }
        });

I had problems trying to find the component by its ID but I found another way to search this component using the context of the same SearchView

// Catch event on [x] button inside search view
int searchCloseButtonId = searchView.getContext().getResources()
                .getIdentifier("android:id/search_close_btn", null, null);
ImageView closeButton = (ImageView) this.searchView.findViewById(searchCloseButtonId);
// Set on click listener
closeButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
       // Manage this event.
    }
});

I use this code to catch text query clearing, and perform my actions

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.search, menu);

        SearchView searchView = (SearchView) menu.findItem(R.id.search_button).getActionView();
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

        SearchView.OnQueryTextListener textChangeListener = new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextChange(String cs) {
                if (TextUtils.isEmpty(cs)){
                    //Text is cleared, do your thing
                }
                return false;
            }

            @Override
            public boolean onQueryTextSubmit(String query) {
                //text query submitted
            }
        };
        searchView.setOnQueryTextListener(textChangeListener);

        return true;
    }

If you use Appcompat library, instead of using

getResources().getIdentifier("android:id/search_close_btn", null, null);

you can do this:

MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchItem.getActionView();
View closeButton = searchView.findViewById(android.support.v7.appcompat.R.id.search_close_btn);
                closeButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        //handle click
                    }
                });

EDIT AUGUST 2019:

If you use androidx: androidx.appcompat.R.id.search_close_btn

回答6:

    ImageView closeButton = (ImageView) this.searchView.findViewById(android.support.v7.appcompat.R.id.search_close_btn);

    closeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // Manage this event.


        }
    });

Use R.id.search_go_btn for "Submit" Button

A kotlin answer:

mySearchView.setOnCloseListener(object : SearchView.OnCloseListener {
            override fun onClose(): Boolean {
                // Do your stuff
                return false
            }
        })
