问题 this is my first ever post to Stack Overflow and it's because I've been tearing my hair out over this issue for the past day. I'm pretty new to jQuery and have a basic understanding of how things work but I'm really struggling with getting a function to loop back on itself after it has processed. It's a simple if/else function that runs through a series of five images to see if they are visible or not. If an image is visible (in other words, the current image in a gallery) then the next and

问题 Can you tell me when we select an item in GalleryView its comes to the center of the screen how to restrict it? I want to just be there where i click that item. How? Simple words, I wanna horizontal Listview. How? Thanks 回答1: HI, I would advise you check the "Hello, Gallery" on the google doc, it is very clear.

问题 I'm an android-newbie and I'm looking for a solution, how to overlap a horizontal-scrolling image-gallery with a vertical-scrolling image-gallery. that means one transparent image of the vertical-scrolling gallery should overlap one image of the horizontal-scrolling gallery (like a cross). furthermore it should be possible to scroll either vertical or horizontal so that the image of the vertical-scrolling gallery or the image of the horizontal-scrolling gallery will change. is there an way ?

问题 I have an image gallery and I want the thumbnails to be cropped at 150px x 150px. The images aren't square - they are rectangular and all different sizes, so I can't set the width and height to 150px because the images will be all squashed and distorted. I'm wondering what other methods there are to do cropping for thumbnails apart from the CSS clip property. Are there any other CSS solutions or perhaps jQuery scripts? 回答1: You can use negative margins to achieve this. DEMO <p class="crop">

问题 I have a ViewPager in which I change images with swype. Now I want to make button which will set current image that user is seeing as wallpaper. How to implement onPageSelected or something similar that will do the job? Code: package com.example.app; import java.io.IOException; import android.app.Activity; import android.app.WallpaperManager; import android.content.Context; import android.os.Bundle; import android.support.v4.view.PagerAdapter; import android.support.v4.view.ViewPager; import

问题 I want to that when a user clicks a button, he can choose gallery or camera, and that the program can retrieve the captured/picked photo. I tried a couple of things, but nothing seems to work completely. This is how I start the gallery so the user can pick a photo: Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(i,3); And this is how I try to retrieve the by the user picked photo: Uri selectedImage = data.getData
