            }
        });
    }

Try this

public class MainActivity extends AppCompatActivity {




    EditText editText;

    @SuppressLint("ClickableViewAccessibility")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        editText = findViewById(R.id.search_edit_frame);

        editText.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (MotionEvent.ACTION_UP == event.getAction()) {

                    if (editText.hasSelection()) {
                        if(!TextUtils.isEmpty(editText.getText().toString())){
                            final int selStart = editText.getSelectionStart();
                            final int selEnd = editText.getSelectionEnd();
                            SpannableString spannableString = new SpannableString(editText.getText().toString());
                            spannableString.setSpan(new StrikethroughSpan(), selStart, selEnd, 0);

                            editText.setText(spannableString);
                            return false;
                        }

                    }


                }
                return false;
            }
        });


    }

Answer 3

can be done by just setting paint flags for editText.

editText.paintFlags = Paint.STRIKE_THRU_TEXT_FLAG

To remove set,

editText.paintFlags = Paint.CURSOR_AFTER
