Today we will talk about the quadraticCurveTo method to draw a curve. quadratic refers to the quadratic equation in mathematics. Next we will introduce the use of the quadraticCurveTo method in detail, if you are interested, you can learn more about how to draw curves in canvas. Today we will talk about quadraticCurveTo. To be honest, this method is a little scary and can be used by function names. In other words, I think it is necessary to shorten the function name. Quadratic refers to the quad

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
