How to find the Text Area(Height/Width) of TextView programmatically in android

I have an EditText, a Button and a TextView. On clicking the button, textview shows the text written in edittext. Is it possible to find the size of textview occupied depending upon text. i.e. If It has three characters "abc", what is width now, if it has 5 characters like "abcde" , then what is the width ?

TextView txt = new TextView(mContext);
txt.setText("Some Text)";
int height = txt.getLineCount() *  txt.getLineHeight();
int width = txt.getWidth();

Please try this:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    TextView edit = (TextView) findViewById(R.id.edit);
    edit.setTextSize(20);       
    edit.setText("Hello, world");       
    edit.measure(0, 0);
    int width = edit.getMeasuredWidth();
    Log.w("width", width.toString());
}

Before you get width, you have to measure the view / label / text edit. Please let me know if this is not working.

please tell me width in??? do you want ?

TextView method getWidth() gives you width of your view, in pixels 

TextView textView = (TextView)findViewById(R.id.textview);
textView.getWidth(); //width of your view, in pixels

Try this way,hope this will help you to solve your problem.

yourTextView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
   @Override
   public void onGlobalLayout() {
     int width = yourTextView.getMeasuredWidth();
     int height = yourTextView.getMeasuredHeight();

   }
});

Rect bounds = new Rect();
Paint textPaint = textView.getPaint();
textPaint.getTextBounds(text,0,text.length(),bounds);
int height = bounds.height();
int width = bounds.width();

or

textView.setText("bla");
textView.measure(0, 0);
textView.getMeasuredWidth();
textView.getMeasuredHeight();
