Its syntax is given belowĪlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this) In order to make an alert dialog, you need to make an object of AlertDialogBuilder which an inner class of AlertDialog. Some times in your application, if you wanted to ask the user about taking a decision between yes or no in response of any particular action taken by the user, by remaining in the same activity and without changing the screen, you can use Alert Dialog. I'd tried all the other solutions out there that I could see on stack overflow etc but none really worked so I wrote my own.Ä«asically by wrapping the text view in a custom linear layout I've been able to successfully measure the text properly by ensuring it is measured with a fixed width.A Dialog is small window that prompts the user to a decision or enter additional information. Stumbled upon this whilst looking for a solution myself. Tv.setTextSize(TypedValue.COMPLEX_UNIT_SP, tv.getTextSize()+0.25f) ĬurrentWidth=tv.getPaint().measureText(s) While((((int)Math.ceil(currentWidth)/tv.getWidth()+scalingFactor)*tv.getTextSize()) #Android wrong syriac font codeThis isn't the most elegant solution, though it was easy to code and it works for me. You'll likely have to play around with the numbers to make it work for your particular application. the if/else if statements) were set by guess-and-check. The parameters necessary to determine the scaling factor (i.e. The static method basically just looks at the number of characters and determines a scaling factor to apply to the TextView's text size, and then incrementally increases the text size until the overall height (an estimated height - using the width of the text, the text height, and the width of the TextView) is just below that of the TextView. The using this approach though, you can create your own similar implementation. 1/2 the screen (with also a 40px top margin and 20px side margins. For instance, this will probably only look good and/or work for a TextView sized to approx. I was able to answer my own question using the following code (see below), but my solution was very specific to the application. even if the text size is far larger than the width or height of the TextView. small relative to the tv.getWidth() and tv.getHeight() values. It always returns small numbers for the text bounds. I think the problem is in the use of tv.getPaint().getTextBounds(.). While(currentBounds.height() =maxViewHeight) Tv.getPaint().getTextBounds(s, 0, s.length(), currentBounds) MinViewHeight = tv.getBackground().getIntrinsicHeight() įinal float maxViewHeight = tv.getHeight() - (tv.getPaddingBottom()+tv.getPaddingTop())-12 // -12 just to be sureįinal String s = tv.getText().toString() get the width of the view's back image (unscaled). Here is what I have so far: public static void autoScaleTextViewTextToHeight(TextView tv) I need it to fit all the lines of the text within the bounds of the TextView. only the first letter is viewable, and it's huge). I'm trying to create a method for resizing multi-line text in a TextView such that it fits within the bounds (both the X and Y dimensions) of the TextView.Īt present, I have something, but all it does is resize the text such that just the first letter/character of the text fills the dimensions of the TextView (i.e. ![]()
