First write the permissions in the AndroidManifest file, take the recording permission as an example

<uses-permission android:name="android.permission.RECORD_AUDIO" />

 if (PermissionUtil.checkPermission(this, Manifest.permission.RECORD_AUDIO, 100)) {
    
    
  //操作
 }

 @Override
 public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    
    
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == 100) {
    
    
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
    
    
                //操作
            } else {
    
    
                Toast.makeText(this, "需要允许录音权限才能录音噢", Toast.LENGTH_SHORT).show();
            }
        }
  }
