First, the shape of the painting can be specified when the shapedrawable is constructed,
Second, you can use Shape.getpaint (). Setshader (); Specify Shader,shader can accept a picture and matrix
So the problem is solved smoothly:
Specifically implemented as follows:[Java]
Copy Code code as follows:
float scale = 1.2f;
int cx = 224;
int cy = 357;
int r = 200;
Specifies that the shape creates a shapedrawable
Shapedrawable shape=new shapedrawable (New OvalShape ());

. However, you can modify its storage directory and file name by using the command:-log-error[=file_name].To facilitate maintenance, there are times when you want to back up the contents of the error log and start recording again, and you can use the MySQL FLUSH LOGS command to tell MySQL to back up the old log files and generate new log files. The backup file name ends with ". old".

problems, the consortium has developed a schema language XML schema.
XML schemas have features that are not available in the following DTDs: Multiple schema comps use XML namespaces, descriptions in XML syntax, and data types that define the content of elements and property values in detail.
Because the data structure in an XML schema is also represented by XML data, the amount of data is much larger than the DTD. However, the XML schema is far more expressive than the DTD, supporting not only
output of JSP pages. Since the JSP page has been compiled into a servlet, the output encoding is also selected according to the operating system's default encoding, unless the output encoding is specified, and the output path is the database, which outputs the string to the database.
From this, the input and output of a Java EE system is very complex, and dynamic changes, and a cross-platform operation, in the actual compilation and operation, may involve different operating systems, if let the
original text and destination interchange I1

integrity and an access-oriented application. 2, InnoDB storage engine (main use is also default)Because the storage engine has a transactional advantage, which supports transactional features such as commit, rollback, and crash resiliency, it consumes more disk space than the MyISAM storage engine. Therefore, when frequent updates and deletions are required and the integrity of the transaction is high, concurrency control needs to be implemented, and the recommended choice is to do so. 3. MEMO
each layer, the layer becomes an array, and each parameter becomes a child of the first DOM object of the previous layer, without any special designation. After a special designation, it becomes a sub-object of the specified object.For example, our above example uses three layers, assuming now I want to put a div under the first TD under the first TR, and want to put a span under the second TD of the secon
1. Basic Explanations extern can be placed before a variable or function to indicate the definition of a variable or function in another file . Tip The compiler finds its definition in other modules when it encounters this variable and function. Also extern can be used for link designation .This means that extern has two functions:A. When it is in conjunction with "C" , such as: extern "C" void fun (int a, int b); tells the compiler to compile the fu
weight of the second rule is 0,0,2,0. Although the second rule has a higher weight, it is a li direct designation for the element, not defined for the span element, so the span computed color attribute weight value is actually inherit the contrast of the red with the directly specified blue. According to the rules, as long as there is a directly specified value (blue), the inherited value (in red) is no longer taken, so span the text in is shown in b
. Why is the upper-level account and lower-level permission group?
2. In the design specified by the superior, there will be a natural logical error. What is this logical error?
------ Answer ------
1. When creating an account, the parent of a new employee is often determined, but the lower level is not determined. Therefore, the lower level uses the permission group to set the operation permissions of the lower level.
2. The upper-level formulation will form a circular
, the performer of the previous node is dynamically specified each time it executes, or only once, and then the first assigned person is executed.System role Selection list: Select the role that can execute the node, and then click the ">" button to add to the right of the current node execution role. In the current node execution role list, you can also set up the current role and the initiator's institutional or departmental relationship, there are three items, no

Second, the server's disks can support PCIe NVMe SSDs, SSDs, and hdd,s2d will default to the best-performing disks as storage bus caches (Storage bus cache), providing read/write caching for each node, as well as storing the metadata for the storage pool. This can be done automatically at configuration time or by manual designation
