Clear focus EditText when back button is pressed when softkeyboard is showing

Question

I know that there are quite some questions out here regarding this question. But non of them have the answer that I'm looking for.

I've got 7 ET inside a ScrollView. When I start the application no ET has focus because I've added the following two lines to my overall layout:

android:focusable="true"
android:focusableInTouchMode="true"

When I click on an ET the softkeyboard is shown, which I want, then I set the value (let say 20). I press a '2' followed by a '0' and then press the back button. At this point the keyboard disappears, but the focus stays. I would like to clear the focus too when pressing the back button to hide the keyboard.

Because when the focus is cleared the layout of the ET is set like I want.

They all have about the some code, which is:

    // Right Cable
    RightCable = (EditText) findViewById (R.id.RightCable);
    RightCable.setRawInputType(Configuration.KEYBOARD_12KEY);
    RightCable.setOnFocusChangeListener(FocusChanged);
    RightCable.addTextChangedListener(new TextWatcher() {
        public void afterTextChanged(Editable s) {
            if(RightCable.isFocused()){
                LengthRightCable       = Double.parseDouble(RightCable.getText().toString());
                Calculate();
            }
        }
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if(s.toString().matches("")) {
                RightCable.setText("0.00");
                Selection.setSelection(RightCable.getText(), 0, 4);
            }
        }
    });

I use a focus listener to change the input of the ET to a number like 5.00 instead of 0.

OnFocusChangeListener FocusChanged = new OnFocusChangeListener() {

    public void onFocusChange(View v, boolean hasFocus) {

        EditText et = (EditText) v;

        et.setSelection(0, et.getText().length());

        if(!hasFocus){
            String userInput = et.getText().toString();

            int dotPos = -1;    

            for (int i = 0; i < userInput.length(); i++) {
                char c = userInput.charAt(i);
                if (c == '.') {
                    dotPos = i;
                }
            }

            if (dotPos == -1){
                et.setText(userInput + ".00");
            } else if(userInput.length() < 5) {
                if ( userInput.length() - dotPos == 1 ) {
                    et.setText(userInput + "00");
                } else if ( userInput.length() - dotPos == 2 ) {
                    et.setText(userInput + "0");
                }
            }
        }
    }

};

 Just override `onBackPressed()` 

method in your activity and check condition for Edittext focus before run super.onBackPressed();

 @Override
            public void onBackPressed() {
        
                if( et_search.isFocused()){
                    et_search.clearFocus();
                }else {
                    super.onBackPressed();
                }
            }
