篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Android 实现无需权限的悬浮球效果，可适配至Android 10相关的知识，希望对你有一定的参考价值。
前言：
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。
- 无需权限！
- 无需权限！
功能：
- 自动贴边
- 显示红点
- 隐藏红点
- 自由移动
- 显示悬浮球
- 隐藏悬浮球
- 销毁悬浮球
- 接入简单，可进行自定义拓展
附上demo地址
效果如下：
以下是主要的代码部分：
MainActivity.class
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
public void onClick(View view)
RoundView.getInstance().hideRoundView(MainActivity.this);
);
findViewById(R.id.closebtn).setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View view)
RoundView.getInstance().closeRoundView(MainActivity.this);
);
findViewById(R.id.showMsgbtn).setOnClickListener(new View.OnClickListener()
@Override

);
findViewById(R.id.hideMsgbtn).setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View view)

);
findViewById(R.id.exitbtn).setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View view)
