you need to calculate the size of your textview and the size of your text. Try this to find size of your text view

int text_view_size = text_view.getLayoutParams().width;

and this for finding the size of your text

 int text_size = getTextSize(text_view.getText().toString());

this is getTextSize method 

private int getTextSize(String your_text){
    Paint p = new Paint();
    //Calculate the text size in pixel
    return p.measureText(your_text);
}

Now you can check using text watTextWatcher class that your text exceeds the size of your text view.

if(textView.getText().toString().trim().length()<=0)
{
      //here your textview has no text
}

Use TextWatcher to see when the text has changed :

private TextView mTextView;
private EditText mEditText;
private final TextWatcher mTextEditorWatcher = new TextWatcher() {
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    public void onTextChanged(CharSequence s, int start, int before, int count) {
       //This sets a textview to the current length
       mTextView.setText(String.valueOf(s.length()));
    }

    public void afterTextChanged(Editable s) {
    }};

Also check this :TextWatcher example
