我是Android App开发的新手。 我按照this toturial编写了一个简单的Google商家信息自动填充Android应用,但是当我开始在应用中输入内容时,它不会返回任何建议。当我在自动完成文本视图中写入任何内容时,它会在LogCat中给出NativeCrypto错误。这是我的代码:
package com.example.newxyz;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLEncoder;

import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;

import android.widget.Filterable;
import android.widget.Toast;
public class GooglePlacesAutocompleteActivity extends Activity implements OnItemClickListener {
private static final String LOG_TAG = "Google Places Autocomplete";
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 = "AIzaSyAujQlZ1Jj64NAHMoynXjI253MVRzGW09w";
private static final String True = "true";
private static final String language = "en";
AutoCompleteTextView autoCompView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
autoCompView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);
autoCompView.setAdapter(new GooglePlacesAutocompleteAdapter(this, R.layout.list_item));
autoCompView.setOnItemClickListener(this);
}
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
String str = (String) adapterView.getItemAtPosition(position);
Toast.makeText(this, str, Toast.LENGTH_SHORT).show();
}
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=" + True);
sb.append("&key=" + API_KEY);
sb.append("&language" + language);
//sb.append("&components=country:gr");
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(LOG_TAG, "Error processing Places API URL", e);
return resultList;
} catch (IOException e) {
Log.e(LOG_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++) {
System.out.println(predsJsonArray.getJSONObject(i).getString("description"));
System.out.println("============================================================");
resultList.add(predsJsonArray.getJSONObject(i).getString("description"));
}
} catch (JSONException e) {
Log.e(LOG_TAG, "Cannot process JSON results", e);
}
return resultList;
}
class GooglePlacesAutocompleteAdapter extends ArrayAdapter<String> implements Filterable {
private ArrayList<String> resultList;
public GooglePlacesAutocompleteAdapter(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 = 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;
}
}
}
这是我的LogCat错误:
05-04 13:16:27.705: E/NativeCrypto(9312): ssl=0x611c0a20 cert_verify_callback x509_store_ctx=0x62625940 arg=0x0

非常感谢任何帮助。 感谢

转到Google Console&gt;&gt; Api&gt;&gt;启用Google Places API网络服务。 见Solution
答案 1 :(得分:0)
我昨天正在打这个问题,所以要么
API_KEY
(例如,您可能会在build.gradle中设置不同的前缀来调试版本或使用错误的SH1或注册到其他一些而不是“Google Places API for Android”)enableAutoManage(fragmentActivity, clientId, connectionCallback)
GoogleApiClient.blockingConnect()
或GoogleApiClient.connect()
调用坦率地说,我对#Google如何完成此API感到高兴。很奇怪,如果你得到代码9001,9006,9007,怎么理解发生了什么?
答案 2 :(得分:0)
就我而言,问题是
"status":"REQUEST_DENIED",
"error_message":"This API project is not authorized to use this API. Please ensure that this API is activated "
该解决方案是在Google Api控制台中启用 Google Places API网络服务。

我喜欢一个解决方案,文本观察者没有任何问题。
在下面的代码中,我没有覆盖&#34; performFiltering&#34;方法。我添加了它,我的自动完整文本框现在正常工作。
public class CustomAutoCompleteView extends AutoCompleteTextView {
public CustomAutoCompleteView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public CustomAutoCompleteView(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
public CustomAutoCompleteView(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
// TODO Auto-generated constructor stub
}
@Override
protected void performFiltering(final CharSequence text, final int keyCode) {
String filterText = "";
super.performFiltering(filterText, keyCode);
}
/**
* After a selection, capture the new value and append to the existing
* text
*/
@Override
protected void replaceText(final CharSequence text) {
super.replaceText(text);
}
}

启用“Google Places API Web服务”API并尝试一下。它对我有用。
答案 5 :(得分:-1)
请尝试做类似的事情:
final StringBuilder sb = new StringBuilder(PLACES_API_BASE + TYPE_AUTOCOMPLETE + OUT_JSON);
sb.append("?key=" + API_KEY);
sb.append("&input=" + URLEncoder.encode(input, "utf8"));
final URL url = new URL(sb.toString());
conn = (HttpURLConnection) url.openConnection();
final InputStreamReader in = new InputStreamReader(conn.getInputStream());
这是我的工作。

The solution is adding googlePlaceApi to project in console.developers.google.com
