It is really a bug in the Android OS inside the Hardware Acceleration modules. I think that the best way is to ask the system to avoid HW acceleration on TextViews that contain large size text. To do so, just add in the code: TextView bigText = (TextView) findViewById(R.id.bigtext); bigText.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
I wanted to edit the answer I had already offered, but then decided it makes more sense to post a new one, because it really depends on the requirements which one I’d prefer. This here probably fits Alan’s idea better, because The middle textblock stays in the middle of the window Fontsize adjustment due to … Read more
I’ve done this in the past using jQuery. You can measure the size of a piece of text like this: // txt is the text to measure, font is the full CSS font declaration, // e.g. “bold 12px Verdana” function measureText(txt, font) { var id = ‘text-width-tester’, $tag = $(‘#’ + id); if (!$tag.length) { … Read more
JavaScript provides two methods for converting non-number primitives into numbers: parseInt() and parseFloat() . As you may have guessed, the former converts a value into an integer whereas the latter converts a value into a floating-point number. Any number literal contained in a string is also converted correctly, so the string “0xA” is properly converted … Read more
Here’s the same answer, but in Javascript var autoSizeText; autoSizeText = function() { var el, elements, _i, _len, _results; elements = $(‘.resize’); console.log(elements); if (elements.length < 0) { return; } _results = []; for (_i = 0, _len = elements.length; _i < _len; _i++) { el = elements[_i]; _results.push((function(el) { var resizeText, _results1; resizeText = … Read more
You can actually get access to the message’s TextView pretty easily, and then change it’s size. I tested with a bigger size, but you could use whatever size you want. The text will scroll nicely as it already does. The view’s id is android.R.id.message AlertDialog dialog = new AlertDialog.Builder(this).setMessage(“Hello world”).show(); TextView textView = (TextView) dialog.findViewById(android.R.id.message); … Read more
Update Before we dive into the code let’s first decide the textSize for our CollapsingToolbarLayout. Google published a website called material.io, this website also explains the best way on how to deal with Typography. The article mentioned about “Heading” category which also explains the recommended font size to use in sp. Although the article never … Read more
ch unit The unit you’re looking for is ch. According to the MDN docs: ch: Represents the width, or more precisely the advance measure, of the glyph “0” (zero, the Unicode character U+0030) in the element’s font. It is supported in current versions of major browsers (caniuse). Example pre { width: 80ch; /* classic terminal … Read more
I have converted dementiazz’s answer to Swift: func updateTextFont() { if (textView.text.isEmpty || CGSizeEqualToSize(textView.bounds.size, CGSizeZero)) { return; } let textViewSize = textView.frame.size; let fixedWidth = textViewSize.width; let expectSize = textView.sizeThatFits(CGSizeMake(fixedWidth, CGFloat(MAXFLOAT))); var expectFont = textView.font; if (expectSize.height > textViewSize.height) { while (textView.sizeThatFits(CGSizeMake(fixedWidth, CGFloat(MAXFLOAT))).height > textViewSize.height) { expectFont = textView.font!.fontWithSize(textView.font!.pointSize – 1) textView.font = expectFont } … Read more
Edit: I don’t recommend this anymore. This approach doesn’t scale well when new devices come out. Use a combination of dynamic font sizes and size classes-specific fonts. Say a new iPhone model comes out, if you are using Auto Layout and Size Classes you don’t have to fix all the constraints manually to make your … Read more
