Bundle extras = getIntent().getExtras();
if (extras != null) {
double value = extras.getDouble("LATITUDE_ID");
//The key argument here must match that used in the other activity
}
为了发送字符串或int值，可以使用putExtra（），但如果要发送LatLng，则需要使用bundle：
Bundle args = new Bundle();
args.putParcelable("customerLatLng", customerLatLng);
Intent intent=new Intent(OldActivity.this,NewActivity.class);
intent.putExtras(args);
startActivity(intent);
Intent i = getIntent();
final Bundle extras = getIntent().getExtras();
LatLng customerLatLng = i.getParcelableExtra("customerLatLng");
我想把纬度和经度分为不同的部分，因为活动发送了坐标来执行这样的代码
public void run() {
// TODO Auto-generated method stub
String handleInserUrl = getResources().getString(
R.string.estate_json_url)
+ "estates";
try {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(handleInserUrl);
MultipartEntity reqEntity = new MultipartEntity();
String titleText = title.getText().toString();
String priceText = price.getText().toString();
String contentText = content.getText().toString();
String bathroomText = bathroom.getText().toString();
String bedroomText = bedroom.getText().toString();
String areaText = area.getText().toString();
String lantaiText = lantai.getText().toString();
String luasbangunanText = luasbangunan.getText().toString();
String addressText = address.getText().toString();
reqEntity.addPart("address", new StringBody(
addressText));
reqEntity.addPart("user_id",
new StringBody(user.getId() + ""));
reqEntity.addPart("title",

在您的侦听器中，使用

R.string.estate_json_url)
