推荐答案

// Find the last picture
String[] projection = new String[]{
    MediaStore.Images.ImageColumns._ID,
    MediaStore.Images.ImageColumns.DATA,
    MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,
    MediaStore.Images.ImageColumns.DATE_TAKEN,
    MediaStore.Images.ImageColumns.MIME_TYPE
    };
final Cursor cursor = getContext().getContentResolver()
        .query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, null, 
               null, MediaStore.Images.ImageColumns.DATE_TAKEN + " DESC");

// Put it in the image view
if (cursor.moveToFirst()) {
    final ImageView imageView = (ImageView) findViewById(R.id.pictureView);
    String imageLocation = cursor.getString(1);
    File imageFile = new File(imageLocation);
    if (imageFile.exists()) {   // TODO: is there a better way to do this?
        Bitmap bm = BitmapFactory.decodeFile(imageLocation);
        imageView.setImageBitmap(bm);         
    }
} 

我仍在处理彩信发送部分.

I'm still working on the MMS sending part.
