通过点击按钮,我从图库中取出图像并将其设置到图像视图中...这里是代码..
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data)
{
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.iImage);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
现在我想在位图变量中获取此图像,需要将其添加到arraylist作为位图varialbe ...任何人都可以帮助我?

您可以将变量用于Bitmap,如:
Bitmap imagetopass;
imagetopass=BitmapFactory.decodeFile(picturePath);
紧随其后:
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
然后你可以使用变量imagetopass。
