所以我試圖在一個Activity中實現兩個API,並在同一Activity中同時顯示我的第二個API的listview和webview。我設法得到了列表視圖。這就是我想要通話雙方通過的onClick方法同時運行的API在MainActivity的一部分如何在一個Activity中顯示listview和webview?
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.twit_list);
activity = this;
Key = getStringFromManifest("CONSUMER_KEY");
Secret = getStringFromManifest("CONSUMER_SECRET");
txtSearch = (EditText) findViewById(R.id.txtSearch);
searchbtn = (Button) findViewById(R.id.searchbtn);
save = (Button) findViewById(R.id.save);
savedSearches = (Button)findViewById(R.id.savedSearches);
searchbtn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view){
downloadSearches();
new GoogleSearch();
}
});
save.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
saveSearch();
}
});
savedSearches.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v){
openSavedSearches();
}
});
}
這是阿比的GoogleSearch公共 無效的onCreate(捆綁savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.twit_list);
txtSearch = (EditText)webView.findViewById(R.id.txtSearch);
searchbtn = (Button) webView.findViewById(R.id.searchbtn);
webView = (WebView)webView.findViewById(R.id.webView);
searchbtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String item = txtSearch.getText().toString();
new JsonSearchTask(item).execute();
}
});
}
private class JsonSearchTask extends AsyncTask<Void, Void, Void> {
String searchResult = "";
String search_url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=";
String search_query;
JsonSearchTask(String item){
try {
search_item = URLEncoder.encode(item, "utf-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
search_query = search_url + search_item;
}
@Override
protected Void doInBackground(Void... arg0) {
try {
searchResult = ParseResult(sendQuery(search_query));
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
@Override
protected void onPreExecute() {
searchbtn.setEnabled(false);
searchbtn.setText("Wait...");
super.onPreExecute();
}
@Override
protected void onPostExecute(Void result) {
webView.loadData(searchResult,
"text/html",
"UTF-8");
searchbtn.setEnabled(true);
searchbtn.setText("Search");
super.onPostExecute(result);
}
}
private String sendQuery(String query) throws IOException{
String result = "";
URL searchURL = new URL(query);
HttpURLConnection httpURLConnection = (HttpURLConnection) searchURL.openConnection();
if(httpURLConnection.getResponseCode() == HttpURLConnection.HTTP_OK){
InputStreamReader inputStreamReader = new InputStreamReader(httpURLConnection.getInputStream());
BufferedReader bufferedReader = new BufferedReader(
inputStreamReader,
8192);
String line = null;
while((line = bufferedReader.readLine()) != null){
result += line;
}
bufferedReader.close();
}
return result;
}
private String ParseResult(String json) throws JSONException{
String parsedResult = "";
JSONObject jsonObject = new JSONObject(json);
JSONObject jsonObject_responseData = jsonObject.getJSONObject("responseData");
JSONArray jsonArray_results = jsonObject_responseData.getJSONArray("results");
//parsedResult += "Google Search APIs (JSON) for : <b>" + search_item + "</b><br/>";
//parsedResult += "Number of results returned = <b>" + jsonArray_results.length() + "</b><br/><br/>";
for(int i = 0; i < jsonArray_results.length(); i++){
JSONObject jsonObject_i = jsonArray_results.getJSONObject(i);
String iTitle = jsonObject_i.getString("title");
String iContent = jsonObject_i.getString("content");
String iUrl = jsonObject_i.getString("url");
parsedResult += "<a href='" + iUrl + "'>" + iTitle + "</a><br/>";
parsedResult += iContent + "<br/><br/>";
}
return parsedResult;
}

基本上我想,當我點擊搜索按鈕同時運行的API。 請有人指出我在正確的方向,我完全是新的這一點。 謝謝
