一、效果展示
系统权限弹框
不再提示后的解释弹框
跳转到应用系统权限页面
二、代码实现
1、设置权限
在manifest文件中配置RECORD_AUDIO权限
<uses-permission android:name="android.permission.RECORD_AUDIO" />
2、UI
简单的button按钮，点击触发动态申请权限逻辑
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<Button
android:id="@+id/btPermission"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="请求mic权限" />
</LinearLayout>
3、代码逻辑
