If you're not satisfied with the UI controls that come with your Android system, you can try a custom control, and we'll take the button as an example, a long time ago Android123 wrote the Android button button control beautification method that mentions the selector constructs of XML. Of course, in addition to using images like Drawable, the Android web today talks about customizing the shape shapes, and supports the following properties on the button control Android shape, gradient, stroke, co

inventory cost and the current period of sales or consumption costs. The average unit cost of inventory is calculated as:
Weighted Average Cost = (total cost of inventory at the beginning of the month + the total cost of stock purchased in monthly)
This case calculates the final inventory commodity cost and the current sales cost according to a weighted average method, as well as the registration result of the inventory commodity breakdown, see the following table:

How does android2.2 change the layout based on gravity sensing? Let's take a detailed analysis of the javasworientationlistener. Java file.
This file contains an important concept and two important arrays, which are of great help for us to understand the screen layout changes caused by mobile phone flip.
Concept: Layout
There are three la s in the official android2.2 system: rotation_0, rotation_90, and rotation_270. Do not confuse the
beginning. These constants represent a specific parameter value. For example, to read the camera model, you can obtain them using the following code.
Metadata metadata = JpegMetadataReader.readMetadata(jpegFile); Directory exif = metadata.getDirectory(ExifDirectory.class); String model = exif.getString(ExifDirectory.TAG_MODEL);
The above mentioned is how to obtain the EXIF information of a photo, which contains a very important information-shooting direction. For example, the im

This effect of the use of the scene is not much, mainly a variety of testing time, such as Garbage clean-up, mobile phone security detection, of course, if you do not want to avoid this effect is ugly, can also be used as a progress bar. Ha ha.
Here are some dry-goods analysis of how this effect can be achieved:
