For articles read online, there can be two black lines in the horizontal direction above, but I can’t adjust them in android studio.

Anyway, I haven’t seen anyone stretch too much through 9.png. Just imagine if there is multi-position stretching, which position is stretching? Is the stretching ratio the same for multiple positions? …… A series of problems will appear.
