Set Imageview to show image in sdcard?

问题

I have a image stored in SD card of my phone. I want to show it in a image view. I know the location of the file. On the oncreate of the activity is there a simple way to say something like

ImageView img = (ImageView) findViewById(R.id.imageView1);    
String path = Environment.getExternalStorageDirectory().toString() "Images/image.jpg";     
img.setsrc = path ;

Please let me know if there is any way to do this. Thank you.

回答1:

Bitmap bmp = BitmapFactory.decodeFile(pathName);
ImageView img;
img.setImageBitmap(bmp);

Hope this helps.

I have this snippet that may help:

File imageFile = new  File("/sdcard/example/image.jpg"); 
if(imageFile.exists()){
    ImageView imageView= (ImageView) findViewById(R.id.imageviewTest);
    imageView.setImageBitmap(BitmapFactory.decodeFile(imageFile.getAbsolutePath()));
}
