Android 6.0 权限申请

在android 6.0开始,部分的权限需要我们动态申请,也就是说当我们的打开app的时候系统不会主动向您申请app所需要的部分权限,需要客户在使用app的时候主动的去申请。

一、权限的申请两步骤:
1、权限申请:

/**
 * @param permissions需要申请的权限
 * @param requestCode申请回调code
 */
 public static void requestPermissions(final @NonNull Activity activity,final @NonNullString[] permissions, final int requestCode)

2、申请回调处理:

 /**

 *@param requestCode申请回调code

 *@param permissions申请的权限

 *@param grantResults返回申请状态PackageManager#PERMISSION_GRANTED(授予) PackageManager#PERMISSION_DENIED(拒绝)

 */

 public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)

二、Fragment中运行时权限的特殊处理
在Fragment中申请权限,不要使用ActivityCompat.requestPermissions, 直接使用Fragment的requestPermissions方法,否则会回调到Activity的onRequestPermissionsResult如果在Fragment中嵌套Fragment,在子Fragment中使用requestPermissions方 法,onRequestPermissionsResult不会回调回来,建议使用 getParentFragment().requestPermissions方法,

这个方法会回调到父Fragment中的onRequestPermissionsResult,加入以下代码可以把回调透传到子Fragment

 @Override

 public void    onRequestPermissionsResult(int requestCode, String[] permissions, int[]    grantResults) {

      super.onRequestPermissionsResult(requestCode,    permissions, grantResults);

      List    fragments = getChildFragmentManager().getFragments();

      if (fragments != null)    {

      for (Fragment    fragment : fragments) {

           if (fragment !=    null) {

                fragment.onRequestPermissionsResult(requestCode,permissions,grantResults);

           }

      }

 }

}

三、权限申请的简单封装

 public class RequestPermissions {

      public static intREQUEST_EXTERNAL_STORAGE = 1;

      public static String[]PERMISSIONS_STORAGE = {

                Manifest.permission.READ_EXTERNAL_STORAGE,

                Manifest.permission.WRITE_EXTERNAL_STORAGE

      };

      /**

      *读写权限申请回调true有权限false无权限

      *

      * @param mContext

      */

      public static voidwriteExternalStorage(final Context mContext, PermissionCallBack mCallBack) {

      //检查是否拥有相应的权限

           int permission =ActivityCompat.checkSelfPermission(mContext,Manifest.permission.WRITE_EXTERNAL_STORAGE);

      //没有权限发起申请

      if (permission !=PackageManager.PERMISSION_GRANTED) {

      //6.0及以上版本才需要申请权限

           if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)

                ActivityCompat.requestPermissions((Activity) mContext,PERMISSIONS_STORAGE,REQUEST_EXTERNAL_STORAGE);

           else {

                mCallBack.setOnPermissionListener(false);

           }

      } else {

           mCallBack.setOnPermissionListener(true);

      }

 }

      /**

      *读写权限申请回调true有权限false无权限

      *

      * @param mContext

      */

 public static voidwriteExternalStorage(final Context mContext, PermissionCallBack mCallBack, intrequestCode) {

      //检查是否拥有相应的权限

      int permission =ActivityCompat.checkSelfPermission(mContext,Manifest.permission.WRITE_EXTERNAL_STORAGE);

      //没有权限发起申请

      if (permission !=PackageManager.PERMISSION_GRANTED) {

           //6.0及以上版本才需要申请权限

           if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)

                ActivityCompat.requestPermissions((Activity) mContext,PERMISSIONS_STORAGE,requestCode);

           else {

                mCallBack.setOnPermissionListener(false);

           }

      } else {

           mCallBack.setOnPermissionListener(true);

      }

 }

 /**

 *权限申请回调,需要在你调用的Activity中onRequestPermissionsResult调用该方法true申请权限成功false申请权限失败

 *

 * @param requestCode

 * @param permissions

 * @param grantResults

 */

 public static void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,@NonNull int[] grantResults, PermissionCallBack mCallBack) {

      if (requestCode ==REQUEST_EXTERNAL_STORAGE) {

           //判断权限是否申请成功

           if(grantResults.length > 0 && grantResults[0] ==PackageManager.PERMISSION_GRANTED) {

                mCallBack.setOnPermissionListener(true);

           } else {

                mCallBack.setOnPermissionListener(false);

           }

           return;

      }

 }

 /**

 * 6.0以下申请打开权限管理

 *

 * @param mContext

 */

 public static void openPre(final Context mContext) {

      RemindDialogUtil.showRemindDialog(mContext, "當前無權限,將無法進行應用升級~,是否打开设置?", new RemindDialogUtil.DialogCallBack() {

           @Override

           public void clickYes() {

                //跳转到设置页面,手动打开权限

                Intent intent= new Intent();

                intent.setAction(Settings.ACTION_APPLICATION_SETTINGS);

                mContext.startActivity(intent);

                RemindDialogUtil.hideRemindDialog();

           }

           @Override

           public voidclickCancel() {

                RemindDialogUtil.hideRemindDialog();

           }

      });

      }

      public interfacePermissionCallBack {

           void setOnPermissionListener(Boolean bo);

      }

 }
