我想绘制我在这里得到的纬度和经度值的坐标
字符串
longitude = c.getString("long"); String latitude = c.getString("lat");
并将其附在按钮上。
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(getActivity(), g.getLatitude() + " " + g.getLongitude(), Toast.LENGTH_SHORT).show();
}
});
