Answer 1

You can register OnFocusChangeListenerin your EditTextinside your action onCreate:

final EditText et = (EditText)findViewById(R.id.my_edit_text);
et.setOnFocusChangeListener(new View.OnFocusChangeListener()
{
    @Override
    public void onFocusChange(View v, boolean hasFocus)
    {
        if (!hasFocus)
            // TODO: the editText has just been left
    }
});

Here the parameter v onFocusChangeis your control EditText.

, TextView EditText, public void afterTextChanged(Editable s) TextWatcher.

//, txtRisk TextView dialogbetNow.

Answer 2

onFocusChangeListener. .

Answer 3

here textMessage is your editext

 textMessage.addTextChangedListener(new TextWatcher(){
            public void afterTextChanged(Editable s) {
                i++;
                tv.setText(textMessage.getText.toString());
            }
            public void beforeTextChanged(CharSequence s, int start, int count, int after){}
            public void onTextChanged(CharSequence s, int start, int before, int count){}
        });
