Add search icon on action bar android
<p>Good days guys.</p>

<p>I have a search icon in action bar as image below</p>

<p><a href="https://i.stack.imgur.com/T6bEp.png" rel="noreferrer"><img src="https://i.stack.imgur.com/T6bEp.png" alt="enter image description here"></a></p>

<p>When it is clicked, I want the action bar change to <code>editText</code> and has a search <code>icon</code> beside the <code>editText</code> </p>

<p>I know how to make an editText with an image, but how to put the editText on the action bar like image below ? And I want to make the data display value once the editText has filled with value. Should I use intent ?</p>

<p>This is what I've tried so far.</p>

<p><strong>Activity A</strong></p>

<pre><code> getData(deviceName, month); // retrieve data from `MySQL` and load into listView

        @Override
         public boolean onCreateOptionsMenu(Menu menu) {
            // Inflate the menu; this adds items to the action bar if it is present.
            MenuInflater inflater = getMenuInflater();
            inflater.inflate(R.menu.create_menu, menu); 
            return true;
        }

        @Override
        public boolean onPrepareOptionsMenu(Menu menu) {
            mSearchAction = menu.findItem(R.id.search);
            return super.onPrepareOptionsMenu(menu);
        }

        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            // Handle action bar item clicks here. The action bar will
            // automatically handle clicks on the Home/Up button, so long
            // as you specify a parent activity in AndroidManifest.xml.
            switch (item.getItemId()) {

                case R.id.search: // should I need to add intent ?
                    handleMenuSearch();
                    return true;

                case R.id.add: // create new file
                    View menuItemView = findViewById(R.id.add);
                    PopupMenu po = new PopupMenu(HomePage.this, menuItemView); //for drop-down menu
                    po.getMenuInflater().inflate(R.menu.popup_menu, po.getMenu());
                    po.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                        public boolean onMenuItemClick(MenuItem item) {
                            //  Toast.makeText(MainActivity.this, "You Clicked : " + item.getTitle(), Toast.LENGTH_SHORT).show();
                            if ("Create New File".equals(item.getTitle())) {

                                startActivity(intent);

<p>When search icon is pressed, it supposed to intent to another page and have a search icon on the editText (exactly like the second image), but it didn't. It remains in the same page.</p>
