UI elements As you can imagine, the Android system is doing everything in the opposite of its competitors (which is called differentiation!). Honeycomb has its own UI specification, and it now has a new "holographic UI" visual language for day-to-day operations such as choosing a time date, selecting an option, setting the volume, and so on. Understanding this UI language is critical to creating screen flow and design layouts. Sample UI elements, one-page slide from Google I/o 2011

Like the in operator, the forin loop traverses all attributes of the prototype chain when searching for object attributes. Use hasOwnProperty Filter Summary Like the in operator, the for in loop traverses all attributes of the prototype chain when searching for object attributes. // Modify the Object. prototypeObject. prototype. bar = 1; var foo = {moo: 2}; for (var I in foo) {console. log (I); // two output attributes: bar and

() method. The Using Keyword can initialize objects that use important resources in a code block. The dispose () method is automatically called at the end of the code block. The usage is as follows: ....

Any class can be inherited from another class, that is, this class has all the members of the class it inherit

Compared with the in operator, for in traverses the prototype chain during the attributes of the loop object. for in does not read non-enumeration attributes, such as The length attribute of an array. Summary when detecting whether an object has a certain attribute, hasOwnProperty is the only method that can complete this task. in the for in loop, we recommend that you add hasOwnProperty for determination, it can effectively avoid errors caused by expanding the local prototype. Compared with th

traversing object attributes. No other method can be used to exclude attributes on the prototype chain, rather than defining attributes on the object itself.However, JavaScript does not protect hasOwnProperty from being illegally occupied. Therefore, if an object happens to have this property, you need to use the external hasOwnProperty function to obtain the correct result.Copy codeThe Code is as follows:Var foo = {HasOwnProperty: function (){Return false;},Bar: 'Here be dragons'};Foo. hasOwnP

In contrast to the in operator, for-in loops through the prototype chain when iterating over the object's properties, for-in does not read an enumerable property, such as the length property of the group. Summary when you detect whether an object owns a property, hasOwnProperty is the only way to accomplish this task, and it is recommended to add hasOwnProperty for the in loop, which can effectively avoid errors caused by extending the local prototype.

will see [undefined, undefined, undefined], which is actually incorrect. Detailed analysis is provided in the previous section.Var arr = new Array (3 );Arr [1]; // undefined1 in arr; // false. The array has not been generated.This method takes precedence over setting the array Length attribute and is only useful in a few cases. for example, loop strings are required to avoid the trouble of for loop.New Array (count + 1). join (stringToRepeat );// Note: new Array (3). join ('#') will return "##"
