如何自动清除EditText中的文本？

EditText editText = findViewById(R.id.editText);
editText.setText("");

EditText editText = findViewById(R.id.editText);
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (!hasFocus) {
            editText.setText("");
        }
    }
});

EditText editText = findViewById(R.id.editText);
editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    }

    @Override
    public void afterTextChanged(Editable s) {
        if (s.toString().isEmpty()) {
            editText.setText("");
        }
    }
});
