Getting height of text view before rendering to layout

Question

Could not find any good solution calculating textview height where text was set before rendering textview to layout. Any help please

Answer 1

From support_ms answer, there is a more simple method that take only a TextView as parameter.

/**
 * Get the TextView height before the TextView will render
 * @param textView the TextView to measure
 * @return the height of the textView
 */
public static int getTextViewHeight(TextView textView) {
    WindowManager wm =
            (WindowManager) textView.getContext().getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();

    int deviceWidth;

    if(android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2){
        Point size = new Point();
        display.getSize(size);
        deviceWidth = size.x;
    } else {
        deviceWidth = display.getWidth();
    }

    int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(deviceWidth, View.MeasureSpec.AT_MOST);
    int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
    textView.measure(widthMeasureSpec, heightMeasureSpec);
    return textView.getMeasuredHeight();
}
