我这样excuting的AsyncTask对象甲:值传递是在Android的
new GeocodeImplementation().execute("D-109 3rd floor ShakarPur Laxmi Nagar New Delhi 110092".replace(" ","%20"));
下面
是我AsyncTask
:
class GeocodeImplementation extends AsyncTask<String, Void, String[]> {
ProgressDialog dialog = new ProgressDialog(DataEntry.this);
@Override
protected void onPreExecute() {
super.onPreExecute();
dialog.setMessage("Please wait...");
dialog.setCanceledOnTouchOutside(false);
dialog.show();
}
@Override
protected String[] doInBackground(String... params) {
String response;
try {
response = GecodeFuncation.getLatLongByURL("http://maps.google.com/maps/api/geocode/json?address="+params+"&sensor=false");
Log.d("response",""+response);
return new String[]{response};
} catch (Exception e) {
return new String[]{"error"};
}
}
@Override
protected void onPostExecute(String... result) {
try {
JSONObject jsonObject = new JSONObject(result[0]);
double lng = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
.getJSONObject("geometry").getJSONObject("location")
.getDouble("lng");
double lat = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
.getJSONObject("geometry").getJSONObject("location")
.getDouble("lat");
Log.d("latitude", "" + lat);
Log.d("longitude", "" + lng);
} catch (JSONException e) {
e.printStackTrace();
}
if (dialog.isShowing()) {
dialog.dismiss();
}
}
}
当我通过地址的AsyncTask然后其网址变为:
http://maps.google.com/maps/api/geocode/json?address=[Ljava.lang.String;@41fff330&sensor=false
所以我无法得到响应,而应该是
这样我就可以得到响应,请告诉我,我做错了。
params为一个字符串...,什么意味着是一个可变参数(字符串数组),而不是字符串,所以你必须通过使用params [0] –
如何访问你的url,存储在第一个位置如何执行taske –
这样做: response = GecodeFuncation.getLatLongByURL(“your url”+ params [0] +“&sensor = false” ); 让一切都保持不变。 –
