How to make images appear in Javascript

问题 I'm not very fluent in javascript, and I feel like this is really basic, but I can't seem to find it online anywhere . I want to create a link that will trigger a javascript function that makes an image appear in a separate div. It can't be in flash, otherwise I have no objection to the coding language. I have several images, so I would think that the best way to do this would be to layer them all on top of each other and then increase the z-index each time their link is clicked, but you

Custom drawing on top of Gallery view (and it's child views)

由 不问归期 提交于 2019-12-07 20:43:19
问题 I'm trying to draw custom UI (a path in this case) on top of a Gallery. I've extended the base Gallery class and overwritten the draw method like this: public class MyGallery extends Gallery { ... @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); canvas.drawPath(mPath, mPaint); } I thought that putting my path drawing after super.onDraw would make sure that the path was drawn on top of the gallery AND it's child views, but instead the child views are layered on top of my

How do I retrieve the Picasa id/URL of an image from the gallery

问题 I have an activity that retrieves images from the device's gallery and uploads to a service. Now, for optimisation purposes, I would like to avoid uploading images that are on Picasa an just store their ID or URL for later retrieval. So my question is, how do I retrieve that information. My intent code is pasted below and retrieves the URI of the image. Intent galleryIntent = new Intent(); galleryIntent.setType("image/*"); galleryIntent.setAction(Intent.ACTION_PICK); startActivityForResult

Change border style in Gallery

由 陌路散爱 提交于 2019-12-07 02:05:53
问题 I am taking this tutorial. As you can see on this image, the standard grey border is applied to all elements in the gallery. I would like to remove this rather ugly border, or, actually, make it a 1 px border instead (or just so the images can be distinguished from each other). I tried removing this line: imgView.setBackgroundResource(GalItemBg); That removes the border, but then the images overlap each other and it's still not very pretty. So, how do I change the border? And how do I get the

How to create a custom gallery having images of a particular folder on SD card?

由 冷暖自知 提交于 2019-12-06 12:03:20
I have seen the API demos of android (/ApiDemos/src/com/example/android/apis/view/Gallery1.java) , but they take images from the res folder within the project. I want to create a gallery of the images which are put up in the folder: /mnt/sdcard/Android/data/com.myapp/files/Pictures/ All i could come up was this code, which, i suppose, displays all images. public class ExistingPicGallery extends Activity { private Cursor cursor; private int columnIndex; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.gallery1); Gallery g
