[移动开发]Android studio 动态获取权限

• PERMISSIONS_STORAGE 可以加入其他权限
• 我这里只写了读和写的权限，根据自己需求添加即可

 private static String[] PERMISSIONS_STORAGE = {android.Manifest.permission.READ_EXTERNAL_STORAGE,//读取外部存储
            android.Manifest.permission.WRITE_EXTERNAL_STORAGE};//写入外部存储
 private static int REQUEST_PERMISSION_CODE = 3;

• 在onCreate中调用即可

    public void getPermission(Activity obj){
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP) {
            for (int i = 0 ; i < PERMISSIONS_STORAGE.length ; i++){
                if (ActivityCompat.checkSelfPermission(obj,
                        PERMISSIONS_STORAGE[i])!= PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions(obj, PERMISSIONS_STORAGE, REQUEST_PERMISSION_CODE);
                }
            }
        }
    }
