简单代码：
public class LaunchActivity extends AppCompatActivity {@Overrideprotected void onCreate(@Nullable Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_launch);if (isGrantSDCardReadPermission()) {//} else {requestPermission();}}private boolean isGrantSDCardReadPermission() {return PermissionUtils.isGrantSDCardReadPermission(this);}private void requestPermission() {PermissionUtils.requestSDCardReadPermission(this, REQUEST_CODE_SDCARD_READ);}private static final int REQUEST_CODE_SDCARD_READ = 1;@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {switch (requestCode) {case REQUEST_CODE_SDCARD_READ:if (isGrantSDCardReadPermission()) {//} else {Toast.makeText(this, "failure because without sd card read permission", Toast.LENGTH_SHORT).show();}break;default:break;}}}public class PermissionUtils {/*** 是否有权限** @param context* @return*/public static boolean checkSelfPermission(Context context, String permission) {if (null == context) {return false;}int per = ContextCompat.checkSelfPermission(context, permission);return per == PackageManager.PERMISSION_GRANTED;}/*** Check that all given permissions have been granted by verifying that each entry in the* given array is of the value {@link PackageManager#PERMISSION_GRANTED}.** @see Activity#onRequestPermissionsResult(int, String[], int[])*/public static boolean verifyPermissions(int[] grantResults) {// At least one result must be checked.if (null == grantResults || grantResults.length < 1) {return false;}// Verify that each required permission has been granted, otherwise return false.for (int result : grantResults) {if (result != PackageManager.PERMISSION_GRANTED) {return false;}}return true;}public static boolean isGrantSDCardReadPermission(Context context) {return checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE);}public static void requestSDCardReadPermission(Activity activity, int requestCode) {ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, requestCode);}
}最后再附上需要动态申请的权限组，每组只要有一个权限申请成功，就默认组内其他权限申请成功了。
