解决方案
下面为c片段的$ C $我都用当我有类似的问题。我给你一个建议提出，D'NT把你的整个code只有一个Java文件。使单独的方法/类在code使用的是每一个不同的任务。它会帮助你更容易地跟踪它。
这是我的PlacesAutoCompleteAdapter.java文件。

进口的java.util.ArrayList;

filterResults.values = resultList;
filterResults.count = resultList.size（）;
}
返回filterResults;

}
};
返回过滤器;
}
}
下面是你必须做什么内部的OnCreate（）的活动。
autoCompView =（AutoCompleteTextView）findViewById（R.id.editloc）;
autoCompView.setAdapter（新PlacesAutoCompleteAdapter（这一点，
R.layout.list_item））;
下面是静态的字符串我已经使用的应用程序。
私有静态最后弦乐PLACES_API_BASE =https://maps.googleapis.com/maps/api/place;
私有静态最后弦乐TYPE_AUTOCOMPLETE =/自动完成;
私有静态最后弦乐OUT_JSON =/ JSON;

和最后在这里，您将在适配器使用的方法。

编辑：
我想您所指定的list_item.xml如下图所示。
＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT; TextView中的xmlns：机器人=http://schemas.android.com/apk/res/android
机器人：layout_width =WRAP_CONTENT机器人：layout_height =WRAP_CONTENT/＆GT;
尝试一下。希望它会帮助你。
更新：
您必须手动附加调试器在仿真写着等待调试器附加。在Netbean的菜单栏中，单击调试，然后选择连接调试......。你必须从流程选择你的包下拉列表中，然后单击连接。这应该这样做。
这在Netbeans的7反正。
或者你可以尝试下面还的事情。
你有两个选择：连接调试器，或者杀死进程。
看你的logcat，你有尝试连接到每个应用程序，这哪里是忽略第二调试器的消息都来自至少两种不同的桌面应用程序。
如果，比如说，是用ADT插件运行Eclipse会发生这种情况，并且独立DDMS同时。我不知道你正在运行或什么NetBeans插件做什么，但我会搞清楚，如果你有争夺控制两个不同的东西开始。
编辑： 如何文本AutoCompleteTextView的
只是写这篇code段。

I am very new to android Google maps i write the following program for displaying the auto sugesstion in the android when i am type the text in the Autocomplete text box it is going the input to the url but the out put is not showing in the program .please see once and let me know where i am doing the mistake.

Thanks in Advance..........
解决方案
Here is the Code Snippet Which i have Used when i have similar problem. i give you one suggestion that D'nt put your whole code in only single java file. Make the separate methods/class for each different task you are using in your code. it will help you easier to trace it.
here is my PlacesAutoCompleteAdapter.java File.
package com.inukshk.adapter;
import java.util.ArrayList;
import android.content.Context;
import android.widget.ArrayAdapter;
import android.widget.Filter;
import android.widget.Filterable;
import com.inukshk.CreateInukshk.CreateInukshk;
public class PlacesAutoCompleteAdapter extends ArrayAdapter<String> implements
Filterable {
private ArrayList<String> resultList;
public PlacesAutoCompleteAdapter(Context context, int textViewResourceId) {
super(context, textViewResourceId);
}
@Override
public int getCount() {
return resultList.size();
}
@Override
public String getItem(int index) {
return resultList.get(index);
}
@Override
public Filter getFilter() {
Filter filter = new Filter() {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults filterResults = new FilterResults();
if (constraint != null) {
// Retrieve the autocomplete results.
resultList = CreateInukshk.autocomplete(constraint
.toString());
// Assign the data to the FilterResults
filterResults.values = resultList;
filterResults.count = resultList.size();
}
return filterResults;
}
@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
if (results != null && results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
};
return filter;
}
}
here is What you have to do inside OnCreate() of your activity.
autoCompView = (AutoCompleteTextView) findViewById(R.id.editloc);
autoCompView.setAdapter(new PlacesAutoCompleteAdapter(this,
R.layout.list_item));
here are the static Strings i have used in app.
private static final String PLACES_API_BASE = "https://maps.googleapis.com/maps/api/place";
private static final String TYPE_AUTOCOMPLETE = "/autocomplete";
private static final String OUT_JSON = "/json";
private static final String API_KEY = "YOUR API KEY";
and Finally here is the Method that you will use in Adapter.
public static ArrayList<String> autocomplete(String input) {
ArrayList<String> resultList = null;
HttpURLConnection conn = null;
StringBuilder jsonResults = new StringBuilder();
try {
StringBuilder sb = new StringBuilder(PLACES_API_BASE
+ TYPE_AUTOCOMPLETE + OUT_JSON);
sb.append("?sensor=false&key=" + API_KEY);
// sb.append("&components=country:uk");
sb.append("&input=" + URLEncoder.encode(input, "utf8"));
URL url = new URL(sb.toString());
conn = (HttpURLConnection) url.openConnection();
InputStreamReader in = new InputStreamReader(conn.getInputStream());
// Load the results into a StringBuilder
int read;
char[] buff = new char[1024];
while ((read = in.read(buff)) != -1) {
jsonResults.append(buff, 0, read);
}
} catch (MalformedURLException e) {
Log.e(TAG, "Error processing Places API URL", e);
return resultList;
} catch (IOException e) {
Log.e(TAG, "Error connecting to Places API", e);
return resultList;
} finally {
if (conn != null) {
conn.disconnect();
}
}
try {
// Create a JSON object hierarchy from the results
JSONObject jsonObj = new JSONObject(jsonResults.toString());
JSONArray predsJsonArray = jsonObj.getJSONArray("predictions");
// Extract the Place descriptions from the results
resultList = new ArrayList<String>(predsJsonArray.length());
for (int i = 0; i < predsJsonArray.length(); i++) {
resultList.add(predsJsonArray.getJSONObject(i).getString(
"description"));
}
} catch (JSONException e) {
Log.e(TAG, "Cannot process JSON results", e);
}
return resultList;
}
EDITED :
i guess you have specified the list_item.xml as below.
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content" />
try it out. Hope it will helps you.
UPDATE :
You have to manually attach the debugger while the emulator says "Waiting for debugger to attach". In Netbean's menu bar, click "Debug", then "Attach Debugger...". You have to select your package from the "Process" drop down list, and then click "Attach". That should do it.
This works in Netbeans 7 anyway.
or you can try out below thing also.
You have two choices: connect a debugger, or kill the process.
Looking at your logcat, you have at least two different desktop applications that are trying to connect to each application process, which is where the "Ignoring second debugger" messages are coming from.
This would happen if you were, say, running Eclipse with the ADT plugin, and the stand-alone DDMS at the same time. I don't know what you're running or what the netbeans plugin does, but I would start by figuring out if you have two different things fighting for control.
EDITED: HOW TO GET TEXT OF AutoCompleteTextView
just write this code snippet.
autoCompView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
YOURTEXT = autoCompView.getText().toString();
//new AsyncGetAutoPlace().execute(autoCompView.getText()
// .toString().trim());
}
});
