我想直接从服务器上的数据中实现搜索。例如从 google.com 搜索。一个edittext，就像在谷歌的搜索栏中，edittext中的一个单词然后它会点击服务器并从该单词开始获取记录。
public class SearchActivity extends Activity {
TextView imeino;
Spinner select;
EditText searchby;
StringBuffer URL;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
imeino = (TextView)findViewById(R.id.getimeino);
TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String device_id = tm.getDeviceId();
imeino.setText(device_id);
searchby = (AutoCompleteTextView)findViewById(R.id.editText1);
//this is a spinner if i choose mobile from this then edittext only takes numeric value.and if a select name then it takes alphabets.
select = (Spinner)findViewById(R.id.spinner1);
select.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
if(select.getSelectedItem().toString().equals("Mobile"))
{
searchby.setInputType(InputType. TYPE_CLASS_PHONE|InputType.TYPE_TEXT_VARIATION_PHONETIC);
}
if(select.getSelectedItem().toString().equals("name"))
{
searchby.setInputType(InputType. TYPE_CLASS_TEXT|InputType.TYPE_TEXT_VARIATION_PERSON_NAME);
}
if(select.getSelectedItem().toString().equals("Address"))
{
searchby.setInputType(InputType. TYPE_CLASS_TEXT|InputType.TYPE_TEXT_VARIATION_POSTAL_ADDRESS);
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
this is my edittext in which i have to search for data
searchby.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
searchby = (AutoCompleteTextView)findViewById(R.id.editText1);
String getitemforsearch = searchby.getText().toString();
SearchFromCustomerData(getitemforsearch);
}
public void SearchFromCustomerData(String getitemforsearch) {
String searchType= new String();
if(select.getSelectedItem().toString().equals("Mobile"))
{
searchType= "CustomerMobile";
}
if(select.getSelectedItem().toString().equals("Address"))
{
searchType= "CustomerAddress";
}
if(select.getSelectedItem().toString().equals("name"))
{
searchType= "CustomerName";
}
这是我访问网络服务的网址，它将显示选项
URL = new StringBuffer("?"+searchType+"=" + getitemforsearch+"&searchType="+searchType);
try {
URL sever = new URL(URL.toString());
System.out.println(URL.toString());
URLConnection yc = sever.openConnection();
InputStream in = yc.getInputStream(); // Get the data in the entity
InputStreamReader is = new InputStreamReader(in);
StringBuilder sb = new StringBuilder();
BufferedReader br = new BufferedReader(is);
String read = br.readLine();
while (read != null) {
sb.append(read);
read = br.readLine();
}
JSONObject jsonObject = new JSONObject(sb.toString());
JSONArray resultArray = jsonObject.getJSONArray("Customer");
System.out.println(" Length :" + resultArray.length());
String[] CustomerCode = new String[resultArray.length()];
String[] CustomerName = new String[resultArray.length()];
String[] CustomerEmail = new String[resultArray.length()];
String[] CustomerMobile = new String[resultArray.length()];
String[] Customeraddress = new String[resultArray.length()];
for (int i = 0; i < resultArray.length(); i++) {
JSONObject object = (JSONObject) resultArray.get(i);
System.out.println("true");
CustomerCode[i] = object.getString("CustomerCode") == null ? "" : object.getString("CustomerCode");
CustomerName[i] = object.getString("CustomerName") == null ? "" : object.getString("CustomerName");
CustomerEmail[i] = object.getString("CustomerEmailId") == null ? "" : object.getString("CustomerEmailId");
CustomerMobile[i] = object.getString("CustomerMobile") == null ? "" : object.getString("CustomerMobile");
Customeraddress[i] = object.getString("CustomerAddress") == null ? "" : object.getString("CustomerAddress");
}
}
catch (Exception e) {
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
@Override
public void afterTextChanged(Editable s) {
}
});
}
}
这是我的布局文件..
