Values begin with a # sign.The first 2 digits represent the transparency of the color, 00~FF, 00 indicates that the color is completely transparent, and FF indicates that the color is completely opaque.The latter 6 digits represent the RGB value of the color. such as: 000000 for Black, ffffff for white, ff0000 for red, 00ff00 for Green, 0000ff for blue, ffff00 for yellow.The following is an example of the background color of the slide-by menu (set to yellow here), which describes transparency.1

android:drawable attribute in the color_selector.xml above, Know that Android should be based on the folder to determine, in the Color folder file has the Android:color property, the file under the Drawable folder has the Android:drawable propertyIt is also important to note that the files referenced by the TextColor and background properties cannot be referenced in a random way, such as textcolor references Drawable_selector.xml,background references Color_ Selector.xml will make an error. So

contribution of different factors to a phenomenon is the so-called detailed analysis model. A lot of things that we seem to be unchanged, in fact, the internal composition of the proportion of the great changes have taken place. And some seemingly changing things, the relative relationship in fact there is no change, but a simple number of fluctuations. 　　 The website says average daily IP/PV visit volume is about 600/2400 means, today visit first page number is 2,400 times, Access IP is 600. T

Class A, and another class B inherits Class A. The following code is available:A = new B (); This is called the parent class's reference A to the subclass object, new B ();If your A is an interface, or an abstract class, then it is not possible to create an object, so that writing can also be used to refer to his subclass or to the object that implements the class. It's not obvious that this sentence is written here. In fact, it is mainly used in the parameters of the method, that is, polymorphi

Meaning of linux folders (the most complete version)/bin: where binary programs live. /boot: the special programs that start the system when you turn the machine on. /dev: aaaaaalll the "device" listings for hardware of every concievable flavor, along with some "imaginary" devices, lile/dev/null and/dev/zero. when you get a random number it usually comes from/dev/random. /etc: configuration files. /home: the user's directories Live here. /lib: the lib

. Therefore, in order to overcome these shortcomings, the stateless (statelessness) architectural style attributes have received extensive attention. Stateless that each maintain their own state, such as session information in the client, the server does not save state information, then we can say that the server is stateless, the benefits are obvious, the stateless parts can be easily replaced (or clustered, scale-out) without state reconstruction (or synchronization), Greatly improved the sc

Meta name KeywordsMeta is an accessible tag in the head area of the HTML language. In almost all pages, we can see HTML code similar to the following:Maybe you think the code is dispensable. In fact, if you can use good meta tags, will bring you unexpected results, such as keywords will be automatically collected by large search sites automatically, you can set the page format and refresh and so on.I. Composition of META tagsMeta tags have a total of two properties, which are the Http-equiv prop

The anonymous inner class (Anonymous Inner Class), when the instance is created, gives the definition of the class, all of which are done in an expression. Java Code ? 1 2 3 4 Runnable rn = new Runnable () { public void Run () { } }; equivalent to: Java Code ? 1 2 3 4 5 class Anomymous implements Runnable { public void Run () { } } Runnable rn = new anomymous (); you can see that the former is more concise.
