每次开新项目都要到处找请求权限的代码，老火得很，这里记录下，方便以后搬运，当然也有很多请求权限的开源项目，

@Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            checkPermission();
        }
    
    
    /**
         * 权限申请
         */
        private void checkPermission() {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                String[] permissions = new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.WRITE_EXTERNAL_STORAGE,
                        Manifest.permission.ACCESS_COARSE_LOCATION};
                for (String permission : permissions) {
                    if (ContextCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
                        ActivityCompat.requestPermissions(this, permissions, 200);
                        return;
                    }
                }
            }
        }
    
        @Override
        public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[]
                grantResults) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && requestCode == 200) {
                for (int i = 0; i < permissions.length; i++) {
                    if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
                        // 如果还是没有获得权限，跳转到当前APP系统设置页面，让用户手动添加权限
                        Intent intent = new Intent();
                        intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                        Uri uri = Uri.fromParts("package", getPackageName(), null);
                        intent.setData(uri);
                        startActivityForResult(intent, 200);
                        return;
                    }
                }
            }
        }
    
        @Override
        protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            if (resultCode == RESULT_OK && requestCode == 200) {
                checkPermission();
            }
        }
