从资产文件夹检索图像路径

Question

I have issue to retrieve image path from assets folder.

I have an image folder in assets folder. Within the folder i have three different folders.

Here is the code that i used:

String IntroImage1= "" + languageSelected + "/" + Intro1ImagePath + ".png" ;


try{
    AssetManager mngr =getAssets();
    InputStream BulletImgInput = mngr.open(IntroImage1);
    //InputStream BulletImgInput = mngr.open("image/Malay/bullet.png");

    Bitmap bitmapBullet = BitmapFactory.decodeStream(BulletImgInput);
    BulletImage.setImageBitmap(bitmapBullet);
    }catch(final IOException e){
    e.printStackTrace();
    }

I am wondering why can't i display the image? Because I have try to retrieve it through this code:

InputStream BulletImgInput = mngr.open("image/Malay/bullet.png");

It did retrieve the file, but with the string that i replaced in mngr.open it doesn't show up.

Really need you guys to help up.Thanks.

Answer 1

You don't need the AssetManager. You can do

BitmapFactory.decodeFile("file:///android_asset/image/Malay/bullet.jpg")

Though storing Images in the Assets is not the best way to go. You will not be able to take advantage of the Android resource management system. So unless you have a compelling reason to do this, I'd suggest that you take a look at using the res folder and the resources system.

Update: Explanation The BitmapFactory has a method to decode a file via the decodeFile method. That's point one. Android lets you access a file in the assets folder via the file:///android_asset/{path} path. In your case, the Image at /image/Malay/bullet.jpg is the assets folder can be accessed via the the file:///android_asset/image/Malay/bullet.jpg .

Answer 2

Try this:

try {

    // get input stream
    InputStream ims = getAssets().open("avatar.jpg");

    // load image as Drawable
    Drawable d = Drawable.createFromStream(ims, null);

    // set image to ImageView
    mImage.setImageDrawable(d);
}
catch(IOException ex) {

      Log.e("I/O ERROR","Failed when ..."
}

your BulletImage

Answer 3

String url = "file:///android_asset/NewFile.txt";

String url = "file:///android_asset/logo.png";

you can access any file....

Answer 4

InputStream BulletImgInput = mngr.open("file:///android_asset/image/Malay/bullet.png");

也许这对你有用。

Answer 5

May be problem is in missed image part of path?

String IntroImage1= "image/" + languageSelected + "/" + Intro1ImagePath + ".png" ;

instead of

String IntroImage1= "" + languageSelected + "/" + Intro1ImagePath + ".png" ;

Upd: Check values of languageSelected and Intro1ImagePath also.
