    </TableLayout>

</RelativeLayout>


 


STEP 3: Add the setOnItemClickListener on the ListView. This need to be added in the DisplayList.java


add setOnItemClickListener


DisplayList.java


package net.kerul.fstmdirektori;

import java.util.ArrayList;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView.OnItemLongClickListener;
import android.widget.ListView;
import android.widget.Toast;

public class DisplayList extends Activity {

    private DBHelper mHelper;
    private SQLiteDatabase dataBase;

    //variables to hold staff records
    private ArrayList<String> stafid = new ArrayList<String>();
    private ArrayList<String> nama = new ArrayList<String>();
    private ArrayList<String> jbt = new ArrayList<String>();

    private ListView userList;
    private AlertDialog.Builder build;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_display_list);

        userList = (ListView) findViewById(R.id.List);

        mHelper = new DBHelper(this);
        
        //click to update data
        userList.setOnItemClickListener(new OnItemClickListener() {

            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {

                Intent i = new Intent(getApplicationContext(),
                        ViewRecord.class);
                i.putExtra("stafid", stafid.get(arg2));
                startActivity(i);

            }
        });
        
        
    }

    @Override
    protected void onResume() {
        //refresh data for screen is invoked/displayed
        displayData();
        super.onResume();
    }

    /**
     * displays data from SQLite
     */
    private void displayData() {
        dataBase = mHelper.getWritableDatabase();
        //the SQL command to fetched all records from the table
        Cursor mCursor = dataBase.rawQuery("SELECT * FROM "
                + DBHelper.TABLE_NAME, null);

        //reset variables
        stafid.clear();
        nama.clear();
        jbt.clear();
        
        //fetch each record
        if (mCursor.moveToFirst()) {
            do {
                //get data from field 
                stafid.add(mCursor.getString(mCursor.getColumnIndex(DBHelper.STAFID)));
                nama.add(mCursor.getString(mCursor.getColumnIndex(DBHelper.NAMA)));
                jbt.add(mCursor.getString(mCursor.getColumnIndex(DBHelper.JBT)));
                
            } while (mCursor.moveToNext());
            //do above till data exhausted 
        }
        
        //display to screen
        DisplayAdapter disadpt = new DisplayAdapter(DisplayList.this, stafid, nama, jbt);
        userList.setAdapter(disadpt);
        mCursor.close();
    }//end displayData
    
    


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.display_list, menu);
        return true;
    }
    
}


 


STEP 4: The code for the second screen (View Record)


code for ViewRecord make callcode for ViewRecord send emailcode for ViewRecord display data from database table


ViewRecord.java


package net.kerul.fstmdirektori;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageButton;

public class ViewRecord extends Activity {
    private EditText txtnama, txtjbt, txttelefon, txtemel;
    private ImageButton btncall, btnemail;
    private DBHelper mHelper;
    private SQLiteDatabase dataBase;
    String id, telno,email,name;//to hold the data strings

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_view_record);
        
        //capture sent parameter from previous screen
        id=getIntent().getExtras().getString("stafid");
        
        //initiate all textbox container to hold the data for the staff
        txtnama=(EditText)findViewById(R.id.txtnama);
        txtjbt=(EditText)findViewById(R.id.txtjbt);
        txttelefon=(EditText)findViewById(R.id.txttelefon);
        txtemel=(EditText)findViewById(R.id.txtemel);
        
        //handling the call
        //be sure to add <uses-permission android:name="android.permission.CALL_PHONE" /> in manifest
        btncall=(ImageButton)findViewById(R.id.btncall);
        btncall.setOnClickListener( new OnClickListener(){
            public void onClick(View v){
                Intent intent = new Intent(Intent.ACTION_CALL);
                intent.setData(Uri.parse("tel:"+telno ));//provide the phone number
                startActivity(intent);//call
            }
        });//end btncall setOnCLickCListener
        
        //handling the email button
        btnemail=(ImageButton)findViewById(R.id.btnemail);
        btnemail.setOnClickListener( new OnClickListener(){
            public void onClick(View v){
                Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto",email, null));
                emailIntent.putExtra(Intent.EXTRA_SUBJECT, "A query about FSTM");//title
                emailIntent.putExtra(Intent.EXTRA_TEXT, "Salaam, "+name);//message body
                startActivity(Intent.createChooser(emailIntent, "Send email..."));//invoke email client chooser
            }
        });//end btnemail setOnCLickCListener
    }
    
    @Override
    protected void onResume() {
        //refresh data for screen is invoked/displayed
        displayData();
        super.onResume();
    }
    
    //display single record of data from stafid
    private void displayData() {
        mHelper=new DBHelper(this);
        dataBase = mHelper.getWritableDatabase();
        //the SQL command to fetched all records from the table
        String sql="SELECT * FROM "
                + DBHelper.TABLE_NAME +" WHERE stafid='"+id+"';";
        Cursor mCursor = dataBase.rawQuery(sql, null);
        
        //fetch the record
        if (mCursor.moveToFirst()) {
            //fetch each field and transfer to textbox
            telno=mCursor.getString(mCursor.getColumnIndex(DBHelper.TELEFON));
            email=mCursor.getString(mCursor.getColumnIndex(DBHelper.EMEL));
            name=mCursor.getString(mCursor.getColumnIndex(DBHelper.NAMA));
            //get data from field and transfer to EditText
            txtnama.setText(name);
            txtjbt.setText(mCursor.getString(mCursor.getColumnIndex(DBHelper.JBT)));
            txttelefon.setText(telno);
            txtemel.setText(email);
                
        }
        else{
            //do something here if no record fetched from database
            txtnama.setText(sql);
        }
    }//end displayData

}


Add additional uses-permission in AndroidManifest.xml to allow call from your app.


uses-permission call AndroidManifest


<uses-permission android:name="android.permission.CALL_PHONE" />


Now you may compile and run the app…

ViewFlipper Example–a simple FlashCard

UPDATE: Improved with Fling gesture (Sept 2012) UPDATE: ViewFlipper with Flip-In and Flip-Out Animation (August 2012) This tutorial is to demonstrate the ViewFlipper layout that is almost similar to CardLayout (in Java). The app will produce a simple Flash card that provide several screens with different picture for each card. Flip-in and Flip-out animation provided. Added in Sept 2012 – an improvement to support Fling gesture – enjoy… The amendment is only on the coding part. Some how the layout design (main.xml) is quite long. Later I’ll produce separated screen by including several XML layout from outside files. Screenshots;

Previously I wrote on why ads are needed to help maintaining an app. Read the article here http://blog.kerul.net/2011/05/generating-revenue-from-free-mobile.html . ---This is quite an old article. You may find the latest supporting AdMob 6.x in here http://blog.kerul.net/2012/08/example-how-to-install-google-admob-6x.html --- This is quite a long tutorial, there are 3 major steps involved. The experiment is done using Windows 7, Eclipse Helios and AdMob SDK 4.1.0 (which currently is the latest-during time of writing). STEP 1: Get the ads from AdMob.com To display the AdMob ads in your Android mobile apps, you need to register first at the admob.com . After completing the registration, login and Add Site/App. Refer to Figure 1. Figure 1 Choose the desired platform and fill in the details (as in Figure 2).
