How to hide other results and just show first result in ListView after Scanned QR Code
0
I'm developing Scan Update App that scan QR Code and update it to Database.
Here is my code for Update to Database.
private void updateDB() throws ClassNotFoundException, SQLException {
int OKcnt = 0;
int NotOKcnt = 0;
String shows = "";
Class.forName("org.postgresql.Driver");
Connection conn = null;
try {
conn = DriverManager.getConnection(
sp.getString("URL","jdbc:postgresql://localhost:5432/Test"),
sp.getString("User","Test"), sp.getString("Pass","Test")
);
for (String scanned : scannedList) {
String splits = scanned.split(",");
String show = "Show Table";
String table = "BedRegistration";
String set = "DocStatus";
String set2 = "IP";
String where = "Name";
String where2 = scanned;
show = splits[0].equals("") ? table :splits [0];
table = splits[1].equals("") ? table : splits[1];
where = splits[2].equals("") ? where : splits[2];
where2 = splits[3].equals("") ? where2 : splits[3];
show = show + ". ";
shows = shows + show ;
String SQL = "UPDATE " + table + " SET ";
String SQLWhere = " WHERE " + where + "='" + where2 + "'";
for (int i = 4; i < splits.length; i=i+2) {
set = splits[i].equals("") ? set : splits[i];
set2 = splits[i+1].equals("") ? set2 : splits[i+1];
SQL += set + " = '" + set2 + "', ";
}
SQL = SQL.substring(0, SQL.length() - 2);
SQL = SQL + SQLWhere;
Statement pstmt = conn.createStatement();
try {
int i = pstmt.executeUpdate(SQL);
System.out.println(SQL+"DB result = "+i);
OKcnt++;
} catch (SQLException e){
NotOKcnt++;
continue;
}
}
And here is my Scan QR Code code.
public void scanBar(View v) {
try {
Intent intent = new Intent(ACTION_SCAN);
intent.putExtra("SCAN_FORMATS", "CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF,CODABAR,EAN_13,EAN_8,UPC_A,QR_CODE");
intent.putExtra("SAVE_HISTORY", false);
startActivityForResult(intent, 0);
} catch (ActivityNotFoundException anfe) {
showDialog(this, "No BarScanner Found", "Download a scanner code activity?", "Yes", "No").show();
}
}
How can i hide other results and just show first result which is String Show.
Coz i have tried someone codes from many sources including stackoverflow, tried to make 2 listview so 1 listview to store all the data and hide it and other listview to store and show just first result but it didn't work.
I have searched for two weeks before i decided to ask question at stackoverflow.
So i really confused right now. I hope someone can help me.
Thanks in advanced :)
PS: Sorry for my english.
Here is my listview and adapter code.
public static final String DB_CONNECTOR = "DB_Connector" ;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(org.starprise.mobile.R.layout.activity_main);
Toolbar myToolbar = (Toolbar) findViewById(org.starprise.mobile.R.id.my_toolbar);
setSupportActionBar(myToolbar);
ActionBar ab = getSupportActionBar();
// Enable the Up button
ab.setDisplayHomeAsUpEnabled(true);
// We get the ListView component from the layout
ListView lv = (ListView) findViewById(R.id.ListView);
itemsAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, scannedList);
lv.setAdapter(itemsAdapter);
Here is Button that i clicked to Update Database.
public void updateDB(View v) {
asyncDBHandling as = new asyncDBHandling(this);
as.execute(sp,scannedList);
//new asyncDBHandling().execute(sp,scannedList);
}
Here is Code to process after Scan QR Code.
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
scannedList.add(contents);
itemsAdapter.notifyDataSetChanged();

In your ListView Adapter, you will probably have a List, ArrayList or any object that grows in size from which your ListView renders it's data.
What determines how many of the data in the ArrayList or List to render is the return value of the getCount() method.
Do something of the sort
package com.fz5.emminent17.adapters;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import java.util.ArrayList;
import java.util.Collections;
/**
* Created by Francis Ilechukwu 20/11/2017.
*/
public class SearchResult Adapter extends BaseAdapter {
private ArrayList<String> searchResults = new ArrayList<>();
private boolean showOnlyFirst = false;
public FacultyAdapter(String searchResults) {
Collections.addAll(this.searchResults, searchResults);
}
public void setShouldShowFirstOnly(boolean showOnlyFirst) {
this.showOnlyFirst = showOnlyFirst;
}
@Override
public int getCount() {
if (showOnlyFirst) {
return 1;
}
return searchResults.size();
}
@Override
public Object getItem(int i) {
return searchResults.get(i);
}
@Override
public long getItemId(int i) {
return 0;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
// Your Normal getView implementation
}
}
Notice the showOnlyFirst boolean, it's a control variable to use on case you want to show all results later or by the press of a button.
However, to show only first, set it to true.

if the format of your results is always constant then you can rely on this code
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
String first_result = contents.substring( 0, contents.indexOf(","));
scannedList.add(first_result);
itemsAdapter.notifyDataSetChanged();
}
}
}

if the format of your results is always constant then you can rely on this code
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
String first_result = contents.substring( 0, contents.indexOf(","));
scannedList.add(first_result);
itemsAdapter.notifyDataSetChanged();
}
}
}
leme know if some problem occurrs

In your ListView Adapter, you will probably have a List, ArrayList or any object that grows in size from which your ListView renders it's data.
What determines how many of the data in the ArrayList or List to render is the return value of the getCount() method.
Do something of the sort
package com.fz5.emminent17.adapters;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import java.util.ArrayList;
import java.util.Collections;
/**
* Created by Francis Ilechukwu 20/11/2017.
*/
public class SearchResult Adapter extends BaseAdapter {
private ArrayList<String> searchResults = new ArrayList<>();
private boolean showOnlyFirst = false;
public FacultyAdapter(String searchResults) {
Collections.addAll(this.searchResults, searchResults);
}
public void setShouldShowFirstOnly(boolean showOnlyFirst) {
this.showOnlyFirst = showOnlyFirst;
}
@Override
public int getCount() {
if (showOnlyFirst) {
return 1;
}
return searchResults.size();
}
@Override
public Object getItem(int i) {
return searchResults.get(i);
}
@Override
public long getItemId(int i) {
return 0;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
// Your Normal getView implementation
}
}
Notice the showOnlyFirst boolean, it's a control variable to use on case you want to show all results later or by the press of a button.
However, to show only first, set it to true.
