Question
Currently my code displays a single image from a file path (in SDCard). This is in onCreate()
method for now:
ImageView imgView01 = (ImageView) findViewById(R.id.imageView1);
File dir = new File("/sdcard/WallpapersHD/");
File file[]=dir.listFiles();
for (int i=0;i<file.length;i++) {
Drawable d = (Drawable) Drawable.createFromPath(file[i].toString());
imgView01.setImageDrawable(d);
}
I want to display all the images in that particular folder one after the other using a time delay of say 5 seconds. If I can create a new drawable for each image in the folder, How do I do it? and how do I change the image in ImageView
to set that drawable's path?
Solution
You could use an ImageSwitcher for convenience, and then do:
imageSwitcher.postDelayed(
new Runnable() {
@Override
public void run() {
i++;
imageSwitcher.setImageURI(Uri.fromFile(file[i]));
imageSwitcher.postDelayed(this, millisBetweenImages);
}
},
millisBetweenImages);
it also has a setImageDrawable-method if you want to keep your images as Drawables.
OTHER TIPS
Create a drawable for each image, and then keep changing the image in your ImageView, perhaps in a Handler or TimerTask.
