好吧,我已经查看了多个示例,我的代码似乎是正确的,但出于某种原因,参数没有添加到 URL 中。我正在尝试连接到 Last.Fm API,我的代码如下:
searchIT.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// TODO Auto-generated method stub
//Create new HTTPClient and Post header
HttpPost API_ROOT = new HttpPost("http://ws.audioscrobbler.com/2.0/");
HttpClient httpclient = new DefaultHttpClient();
try
{
//Add Data
List<NameValuePair> nameValPairs = new ArrayList<NameValuePair>(4);
nameValPairs.add(new BasicNameValuePair("method", "artist.getevents")); //Get events for artist
nameValPairs.add(new BasicNameValuePair("artist", namesBox.getText().toString())); //Get artist name
nameValPairs.add(new BasicNameValuePair("autocorrect", "1")); //Turn on AutoCorrect
nameValPairs.add(new BasicNameValuePair("api_key", "xxxxxxxxxxxxxxxxxxxx")); //API Key - redacted for privacy
API_ROOT.setEntity(new UrlEncodedFormEntity(nameValPairs));
Log.i(TAG, "URL: " + API_ROOT.getURI().toString());
//Execute HTTP Post Request
HttpResponse response = httpclient.execute(API_ROOT);
}
catch (UnsupportedEncodingException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
我在这里错过了什么吗?在日志中,网址显示为:http://ws.audioscrobbler.com/2.0/,因此它似乎缺少我试图传递给它的所有参数。有什么想法、提示、更正或建议吗?
从 onClick 方法启动一个新活动并传递您想要的所有参数
HashMap<String, String> o = (HashMap<String, String>) searchList.getItemAtPosition(position);
Intent i = new Intent(SearchActivity.this, SearchDetails.class);
i.putExtra("method", o.get("method"));
i.putExtra("artist", o.get("artist"));
i.putExtra("autocorrect", o.get("autocorrect"));
i.putExtra("api_key", o.get("api_key"));
然后在您的新活动中:在 onCreate 方法中
Intent myIntent = getIntent();
String method= myIntent.getStringExtra("method");
String artist= myIntent.getStringExtra("artist");
String autocorrect= myIntent.getStringExtra("autocorrect");
String api_key= myIntent.getStringExtra("api_key");
现在您将根据需要获取参数并将它们添加到您的 URL 中。
希望有效果
