1.引入依赖:
implementation 'pub.devrel:easypermissions:3.0.0'2.在BaseActivity处理统一的结果回调和请求Code
核心内容:
(1)处理Activity本身继承的方法onRequestPermissionsResult
(2)实现接口EasyPermissions.PermissionCallbacks来接收请求结果
(3)定义申请权限跳转带出去的Code(Int类型,合法范围0-255)
(4)定义PermissionsCallBack是对结果返回的进一步简化 (非必须)

abstract class BaseActivity : AppCompatActivity() , EasyPermissions.PermissionCallbacks{
var mPermCodeBLE: Int = 11
var mPermCodeAUDIO: Int = 12
// 用户给予相关权限成功后的回调
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<String>,
grantResults: IntArray
) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults)
// 进一步使用 EasyPermissions 处理后续结果
EasyPermissions.onRequestPermissionsResult(
requestCode, permissions, grantResults, this)
}
override fun onPermissionsGranted(requestCode: Int, perms: MutableList<String>) {
// 授予权限
mPermissionsCallBack?.let {
it.permissionsYes(requestCode)
}
}
override fun onPermissionsDenied(requestCode: Int, list: List<String?>) {
// 请求权限被拒
mPermissionsCallBack?.let {
it.permissionsNo(requestCode)
}
}
var mPermissionsCallBack: PermissionsCallBack? = null
interface PermissionsCallBack {
fun permissionsYes(code: Int) //获取授权成功
fun permissionsNo(code: Int) //获取授权成功
}
// 获取蓝牙相关的权限
fun getBlePerm(): Array<String> {
return when {
Build.VERSION.SDK_INT >= Build.VERSION_CODES.S -> arrayOf(
Manifest.permission.BLUETOOTH_SCAN,
Manifest.permission.BLUETOOTH_CONNECT,
Manifest.permission.BLUETOOTH_ADVERTISE,
Manifest.permission.ACCESS_FINE_LOCATION
)
Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q -> arrayOf(
Manifest.permission.BLUETOOTH_ADMIN,
Manifest.permission.ACCESS_FINE_LOCATION
)
else -> arrayOf(
Manifest.permission.BLUETOOTH_ADMIN,
Manifest.permission.ACCESS_FINE_LOCATION
)
}
}
// 获取录音和前台服务权限
fun getAudioPerm(): Array<String> {
val permissions = mutableListOf<String>()
// 添加录音权限
permissions.add(Manifest.permission.RECORD_AUDIO)
// 根据 Android 版本添加前台服务权限
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
permissions.add(Manifest.permission.FOREGROUND_SERVICE)
}
return permissions.toTypedArray()
}
}3具体请求用蓝牙举例:
//权限判断，第一次弹出系统的授权提示框
if (EasyPermissions.hasPermissions(this, *getBlePerm())) {
if (!((activity?.getSystemService(Context.BLUETOOTH_SERVICE) as BluetoothManager).adapter.isEnabled)) {
//打开蓝牙开关
activity?.startActivity(Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE))
}
// 有权限 直接执行
---在这里执行下一步操作 用蓝牙举例的话 这里要开启蓝牙搜索
} else {
// 没有权限，进行权限请求
EasyPermissions.requestPermissions(
this,
getString("需要赋予相关权限,方能正常使用该功能!"),
mPermCodeBLE,
*getBlePerm()
)
}
mPermissionsCallBack = object :PermissionsCallBack{
override fun permissionsYes(code: Int) {
---在这里执行下一步操作 用蓝牙举例的话 这里要开启蓝牙搜索
}
override fun permissionsNo(code: Int) {
}
}
