我知道如何从
android中的相册中获取照片
Intent gallery = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(gallery,PHOTO_REQUEST_CODE);
但是我如何专门选择缩略图？
BOUNTY的原因：
我已经在Get thumbnail Uri/path of the image stored in sd card + android尝试了两种解决方案.他们不适合我.我不知道如何从数据中获取selectedImageUri,类型为long
onActivityResult(int requestCode,int resultCode,Intent data)
解决方法
String fn = ...; // file name
ContentResolver cr = ctx.getContentResolver();
Cursor c = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,new String[]{
BaseColumns._ID
},MediaColumns.DATA + "=?",new String[]{ fn },null);
if(c!=null) {
try{
if(c.moveToNext()) {
long id = c.getLong(0);
Bitmap thumbnail = MediaStore.Images.Thumbnails.getThumbnail(cr,id,MediaStore.Images.Thumbnails.MINI_KIND,null);
}
}finally{
c.close();
}
}
