最近闲来无事，突然想起搞一下悬浮球，之前的项目的悬浮球一直都需要授权，android6.0以后需要手动授权，悬浮球使用时就非常不便，这里为大家带来一种无需权限的悬浮球实现方式。
附上demo地址
效果如下：
以下是主要的代码部分：

public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.showbtn).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
RoundView.getInstance().showRoundView(MainActivity.this);
}
});
findViewById(R.id.hidebtn).setOnClickListener(new View.OnClickListener() {
@Override
