TEXTSIZE填补屏幕宽度 [英] Textsize to fill screen width
问题描述
我在我的应用程序倒计时功能。
每一秒的定时器设置当前时间，一个TextView。
所以字符串是：56:05，56:04，56:03，56:02......
I have countdown functionality in my app. Every second a timer sets the current time to a TextView. So strings are: "56:05","56:04","56:03","56:02"...
我想使文本尺寸尽可能大
I want to make the text size as big as possible
所以我写了下面的code。
Therefore I've written the following code.
private void measureAndSetText(String text) {
Paint pMeasure = new Paint();
Integer iWidth = _tvContent.getWidth();
Float maxTextSize = 1000f;
pMeasure.setTextSize(maxTextSize);
pMeasure.setFakeBoldText(true);
Float fCurrentWidth = pMeasure.measureText(text);
while (fCurrentWidth > iWidth) {
pMeasure.setTextSize(maxTextSize -= 1);
fCurrentWidth = pMeasure.measureText(text);
}
_tvContent.setText(text);
_tvContent.setTextSize(TypedValue.COMPLEX_UNIT_PX, maxTextSize);
}
这code似乎在我的注2，LG擎天柱4X HD，Galay ACE和其他一些工作。
却没有关于我的Xperia中的Z横向模式。
我想原因是全高清显示屏，但我不明白为什么。
上了Xperiaž只是：符号显示在横向模式。因此，我认为该文本被包裹，但我不知道为什么。
这将是有意义的我，如果我设置它的文字大小比屏幕高度较高（在横向模式下这实际上是屏幕的宽度 - > 1080），但事实并非如此。
当我尝试设置一个较长的文本 - >asdfasd ASDF这是正确显示
This code seems to work on my Note2, Lg Optimus 4x HD, Galay ACE and some others. But not on my Xperia Z in landscape mode. I guess the reason is the Full Hd Display but I don't understand why. On the Xperia Z just the ":" sign is displayed in landscape mode. So I think the text is wrapped but I don't know why. It would make sense to me if the text size I set to it is higher than the screen height (in landscape mode this is actually screen width -> 1080) but this isn't the case. When I try to set a longer text -> "asdfasd asdf" it is correctly displayed.
有人能指出我的问题？
干杯，

更新：
我想通了，我持有我的TextView的宽度iWidth变量（_tvContent.getWidth（））的值为1770。
怎么会是这样，因为我的Xperia Z具有1920×1080只???
UPDATE: I figured out that my iWidth variable which holds the width of my TextView (_tvContent.getWidth()) has the value 1770. How can that be since my Xperia Z has just 1920x1080???
所以，我认为这可能是TextView.getWidth失败（），并增加了以下code：
So I thought that it may be a failure in TextView.getWidth() and added the following code:
Display display3 = getWindowManager().getDefaultDisplay();
Point size3 = new Point();
display3.getSize(size3);
int width = size3.x;
Display display1 = getWindowManager().getDefaultDisplay();
int width1 = display1.getWidth(); // deprecated
int height1 = display1.getHeight(); // deprecated
Display display = getWindowManager().getDefaultDisplay();
Integer iWidth = display.getWidth(); // deprecated
int height = display.getHeight(); // deprecated
结果：
点（1080，1776）
Point(1080, 1776)
显示ID 0：DisplayInfo {Integrierter Bildschirm，应用1080点¯x1776年实际1080点¯x1920年，最大的应用1794点¯x1701年最小的应用1080点¯x1005 60.0 FPS，旋转0，密度480，442.451点¯x443.345 DPI，层堆叠0，类型BUILT_IN，地址为null，FLAG_SECURE，FLAG_SUPPORTS_PROTECTED_BUFFERS}，{DisplayMetrics密度= 3.0，宽= 1080，高度= 1776，scaledDensity = 3.0，xdpi = 442.451，ydpi = 443.345}的isValid = TRUE
Display id 0: DisplayInfo{"Integrierter Bildschirm", app 1080 x 1776, real 1080 x 1920, largest app 1794 x 1701, smallest app 1080 x 1005, 60.0 fps, rotation 0, density 480, 442.451 x 443.345 dpi, layerStack 0, type BUILT_IN, address null, FLAG_SECURE, FLAG_SUPPORTS_PROTECTED_BUFFERS}, DisplayMetrics{density=3.0, width=1080, height=1776, scaledDensity=3.0, xdpi=442.451, ydpi=443.345}, isValid=true

推荐答案
我实现我自己的TextView有自己的OnDraw后，我见过的，有在LogCat中的错误：ERROR / OpenGLRenderer（2503）：字体大小大适合在高速缓存中。
After I implemented my own TextView with its own OnDraw I've seen that there is an error in LogCat: ERROR/OpenGLRenderer(2503): Font size to large to fit in cache.
经过短暂的研究，我figgured指出，这是真正在Android中的一个Bug。
After a short research I figgured out that this is really a Bug in Android.
Addding此行我的自定义的TextView的伎俩对我来说：
Addding this line to my custom TextView did the trick for me:
this.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
