Answer 1

You will want to implement Textwatcher and in the onTextChanged(...) method, call TextView's setEms(...) method, which will set the width of the TextView to the width of (n m's), where n is the input for setEms(...).

...
TextView tv = (TextView) findViewById(R.id.my_text_view);
tv.addTextChangedListener(this);
...
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
    tv.setEms(count);
}
