Android 实现无需权限的悬浮球效果，可适配至Android 10

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：

在这里插入图片描述

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 public void onClick(View view) { RoundView.getInstance().showRoundMsg(); } }); findViewById(R.id.hideMsgbtn).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { RoundView.getInstance().hideRoundMsg(); } }); findViewById(R.id.exitbtn).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { android.os.Process.killProcess(android.os.Process.myPid()); } }); } }
