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

Lineparameter DLG;

Return;
}
M_colorr = DLG. m_colorr;
M_colorg = DLG. m_colorg;
M_colorb = DLG. m_colorb;
M_linewidth = DLG. m_penwidth;
// Delete dialog box

3. Modify the onmousemove message processing function and assign the value of the corresponding member variables of the cxxxxview class to the parameters required for drawing (RGB color and line width)
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

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

Introduction to coordinate systemIllustrates the Java coordinate system. The coordinate origin is in the upper-left corner, in pixels, which is the smallest display unit on the computer screen. In the Java coordinate system, the first is the x-coordinate, which indicates that the current position is horizontal, the origin of the coordinates is x pixels, and the second is the y-coordinate, which indicates that the current position is in the vertical direction, and y pixels from the origin of the
PrefaceAn excellent application is not only to have attractive features and interactions, but also to have high performance requirements. Mobile phone running Android system, although the configuration in the continuous upgrade, but still can not be compared with the PC, the PC does not have the same large memory and high-performance CPU, so in the development of Android applications can not be unlimited use of CPU and memory, Improper use of CPU and memory can also cause problems such as applic
