Code (Android-Java)
public class MainActivity extends Activity {
@SuppressLint("NewApi")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Permission StrictMode
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
final Button btn1 = (Button) findViewById(R.id.button1);
// Perform action on click
btn1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
SearchData();
}
});
}
public void SearchData()
{
// listView1
final ListView lisView1 = (ListView)findViewById(R.id.listView1);
// editText1
final EditText inputText = (EditText)findViewById(R.id.editText1);
String url = "https://www.thaicreate.com/android/getJSON.php";
// Paste Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("txtKeyword", inputText.getText().toString()));
try {
JSONArray data = new JSONArray(getJSONUrl(url,params));
final ArrayList<HashMap<String, String>> MyArrList = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map;
for(int i = 0; i < data.length(); i++){
JSONObject c = data.getJSONObject(i);
map = new HashMap<String, String>();
map.put("CustomerID", c.getString("CustomerID"));
map.put("Name", c.getString("Name"));
map.put("Email", c.getString("Email"));
map.put("CountryCode", c.getString("CountryCode"));
map.put("Budget", c.getString("Budget"));
map.put("Used", c.getString("Used"));
MyArrList.add(map);
}
SimpleAdapter sAdap;
sAdap = new SimpleAdapter(MainActivity.this, MyArrList, R.layout.activity_column,
new String[] {"CustomerID", "Name", "Email"}, new int[] {R.id.ColCustomerID, R.id.ColName, R.id.ColEmail});
lisView1.setAdapter(sAdap);
final AlertDialog.Builder viewDetail = new AlertDialog.Builder(this);
// OnClick Item
lisView1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView,
int position, long mylng) {
String strCustomerID = MyArrList.get(position).get("CustomerID")
.toString();
String sName = MyArrList.get(position).get("Name")
.toString();
String strEmail = MyArrList.get(position).get("Email")
.toString();
String strCounryCode = MyArrList.get(position).get("CounryCode")
.toString();
String strBudget = MyArrList.get(position).get("Budget")
.toString();
String strUsed = MyArrList.get(position).get("Used")
.toString();
viewDetail.setIcon(android.R.drawable.btn_star_big_on);
viewDetail.setTitle("Member Detail");
viewDetail.setMessage("MemberID : " + strCustomerID + "\n"
+ "Name : " + sName + "\n"
+ "strEmail : " + strEmail + "\n"
+ "strCounryCode : " + strCounryCode + "\n"
+ "strBudget : " + strBudget + "\n"
+ "Used : " + strUsed);
viewDetail.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
viewDetail.show();
