vertical constraint to him, then the program will be error when running, the wrong content: "Unable to simultaneously satisfy Constraints ... "; Code Description:
2. So before adding a new constraint, we have to remove the corresponding constraint previously added to our component; The constraint is added to the parent view of our corresponding component and removed from the parent view of the component;
3. When setting the value of a constraint, we pass the argument to the constraint

When doing a project, an app often needs a ' live ' display instead of a fixed width, such as when using the GridView to display pictures:Of course, the number of columns is fixed, but what we need is that the aspect ratio of the picture will not become, the size of the picture is still to be done. So there is the following configurationAssume that the aspect ratio of the picture is 16:9:1Item_relatlayout =(relativelayout) Itemview.findviewbyid (r.id.item_relatlayout);2ImageView =(ImageView) Ite

If the constraint has onlyThe constraint of the function value is called Lagrange interpolation, otherwise it is called as Hermite interpolation value.In geometric sense, fitting is given a number of points in the space, finding a continuous surface with unknown parameters of known form to maximize the approximation of these points, and the interpolation is to find one (or several shards of smooth) continuous surfaces to pass thr

This is the topic of our 15-level freshman warm-up, when few freshmen came, not only because they did not learn DP, but also because it is not a small white full backpack, here is given a value of M, let us choose certain items to make their value >=m, let us ask for the minimum cost.First of all clear M is not as a backpack capacity, because our value may be greater than m, in fact, let us ask for the minimum cost, we are undoubtedly in the beginning to initialize the DP to infinity, so natural

Screen Size: The diagonal length of the actual phone's main screen, such as iphone 4.7 inch;
Resolution: With the computer monitor resolution, such as 1334x750 pixels;
Pixel density (DPI pixels per inch): Compresses the resolution to the screen size, such as the 1334/phone length, such as more than 326 pixels per inch, becomes "retina"
Dip: device independent pixels, is a logical density calculated value, with a screen density of 160 mobile phone as sta

5. After-sales service to meet requirements
Reliable ECs providers should support technical services, including holidays. In this case, the after-sales service response and problem handling efficiency will be relatively high, which can avoid more losses to enterprises. Some vendors provide such services free of charge, while some suppliers charge different fees.
