The XML layout (open the one in layout forlder)

layout design for ViewRecord

The XML code

</TableRow>

</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…
