The view component of Android is displayed mainly through three processes: mesure, layout, and draw. In the mesure stage, call the mesure (INT widthspec, int heightspec) method. The final method cannot be overwritten. In this process, the onmesure (INT widthspec, int heightspec) method is called. After the component size is set, call the final layout (int l, int T, int R, int B) method for layout. In this process, onlayout (Boolean changed, int L, int T, int R, int B) method. Therefore, the onme

The computer has brought us great convenience in life and work, which has greatly improved our efficiency. One of the computer with a "paint"-image processing, for us to simply deal with some pictures to bring convenience. The paint tool can handle picture proportions/dimensions, pixels, picture tilt angles, picture erasure features (erase unwanted parts), add text (notes) to the picture, and more. Here's a list of common features: Adjust the proportions of the picture or pixel size, throug

The last word describes some of the basic principles of view drawing, which continues to unfold. Uibezierpath can draw lots of interesting graphics.Using different constructors, such as Roundedrect, are four rounded rectangles, or simply ellipses and circles. You can even cut any path, cut using the Addclip method, and after clipping you can manipulate this part of the cut, for example, if you are drawing a

Three-dimensional graphic rendering is relatively difficult. The first is to determine a good perspective relationship, you can use lines to pull out a simple perspective line, different graphics need different lines. Then on the perspective line to draw a reasonable drawing of the physical drawings. Later color, rendering texture can be. Final effect 1, first dozen good grid line, bright spot perspective. I recommend finding a square object first
