Geocode 没有返回值的问题

我想把地址转换成long和纬度型，但是它返回0。请大家帮我看看错误出现在哪里？
代码如下：

geocoder = new Geocoder(this);
buttonSave.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        try {
            EditText loc = (EditText)findViewById(R.id.txtAddress);
            String locationName = loc.getText().toString();
            List<Address> addressList = geocoder.getFromLocationName(locationName, 2);
            if(addressList!=null && addressList.size()>0) {
                lat = (int)(addressList.get(0).getLatitude()*1000000);
                lng = (int)(addressList.get(0).getLongitude()*1000000);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        lattitude = Integer.toString(lat);
        longertude = Integer.toString(lng);

解决方案

你代码明明转换成int。
不需要强制转换为int
