如何在EditText中选择文本并为Android中的RTF编辑提供工具提示

Question

How can we select a part of the text in EditText. And after selecting that part of the text, how can we provide a tooltip to make that text rich, ie providing different toggle button kind of things in the tooltip to change the fontstyle, color, bold, italics etc.

Answer 1

private class CustomTextWatcher implements TextWatcher 
{
    private EditText myEditText;

    public CustomTextWatcher(EditText e) 
    {
        myEditText = e;
    }

    public void beforeTextChanged(CharSequence s, int start, int count,int after) 
    {

    }

    public void onTextChanged(CharSequence s, int start, int before,
            int count) {
        //do the stuff you want to do here.
    }

    @Override
    public void afterTextChanged(Editable arg0) {

    }
}
