How to hide/show keyboard based on edittext enable and disable.

below is code we are using in view holder class of recyclerview

public class CountItemViewHolder extends RecyclerView.ViewHolder {
    EditText textView;
    View containerView;
    Context context;
    Boolean flag=false;
    ImageButton button1;
    public CountItemViewHolder(View itemView, Context context) {
        super(itemView);
        textView = (EditText) itemView.findViewById(R.id.username);
        containerView = (View) itemView.findViewById(R.id.container);
        button1 = (ImageButton) itemView.findViewById(R.id.button1);
        this.context = context;
    }
    public void render(String text){
        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                System.out.println("click hua");
                InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
                if(!flag) {

                    button1.setImageResource(R.mipmap.checked_icon);
                    textView.setEnabled(true);
                    textView.setFocusable(true);
                    textView.setFocusableInTouchMode(true);
                    textView.setCursorVisible(true);
                    textView.setInputType(InputType.TYPE_CLASS_TEXT); // disable soft input

                    textView.requestFocus();
                    imm.showSoftInput(textView, InputMethodManager.SHOW_IMPLICIT);
                    flag = true;
                }else{
                    button1.setImageResource(R.mipmap.edit_icon);
                    imm.hideSoftInputFromWindow(textView.getWindowToken(), 0);

                    disableEditText(textView);



                    flag = false;

                }

        textView.setOnEditorActionListener(new EditText.OnEditorActionListener() {
            @Override
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                if (actionId == EditorInfo.IME_ACTION_DONE) {
                    System.out.println("keyboard close");
                    InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);

                    imm.hideSoftInputFromWindow(textView.getWindowToken(), 0);

                    disableEditText(textView);

                    return true;

Answer 1

For Show the Keyboard

InputMethodManager keyboard = (InputMethodManager)
            getSystemService(Context.INPUT_METHOD_SERVICE);
            keyboard.showSoftInput(yourEdittext, 0);

For Hide the keyboard.(This will hide the keyboard when you click done button)

InputMethodManager keyboard = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
keyboard.hideSoftInputFromWindow(yourEdittext.getView().getWindowToken(), 0);

UPDATE

yourEdittext.setOnKeyListener(new View.OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if ((event.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) {
            yourEdittext.setEnable(false);
            return true;
        }
        return false;
    }
});
