Android QQ Login interface encountered problems and solutions _android

Let's show you the effect chart:

The first of several problems encountered in the process:

1, the edittext to customize the background

2, the runtime automatic edittext automatically get focus

3, when the focus is to clear the hint, rather than empty after the input

4, the opportunity to empty the button (when the focus and have input content)

.........

---these problems are solved in one by one---

Here's the code:
