The Java code to perform Save New Record.


AddNewRecord.java


package net.kerul.fstmdirektori;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.ContentValues;
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;

public class AddNewRecord extends Activity {
private EditText txtnama, txtjbt, txttelefon, txtemel;
private Button btnsave;
private DBHelper mHelper;
private SQLiteDatabase dataBase;
private String id,name,telno,email,dept;//to hold the data strings

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_new_record);

mHelper=new DBHelper(this);
dataBase = mHelper.getWritableDatabase();

//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);

btnsave=(Button)findViewById(R.id.btnsavenew);
btnsave.setOnClickListener( new OnClickListener(){
public void onClick(View v){
//capture amendment
name=txtnama.getText().toString();
telno=txttelefon.getText().toString();
email=txtemel.getText().toString();
dept=txtjbt.getText().toString();

saveData();
}
});//end btnsave setOnCLickCListener
}

//save new record
private void saveData(){
ContentValues values=new ContentValues();

values.put(DBHelper.NAMA,name);
values.put(DBHelper.JBT,dept);
values.put(DBHelper.EMEL,email );
values.put(DBHelper.TELEFON,telno );

System.out.println("");

//save new record to the database into database
dataBase.insert(DBHelper.TABLE_NAME, null, values);

//close database
dataBase.close();
finish();


}

}



 


STEP 3: Add MENU on ActionBar to call the AddNewRecord screen


add-new-record-menu-add


Get back to the main screen (DisplayList.java). Add the onCreateOptionsMenu and onOptionsItemSelected in the DisplayList.java


add-new-record invoke screen from menu


DisplayList.java – updated

startActivity(i);
return true;
}
});//end setOnItemLongClickListener


}

@Override
protected void onResume() {
//refresh data for screen is invoked/displayed
displayData();
Toast.makeText(getApplicationContext(), "TAP on rescord to view complete info, \n LONG-TAP to update...", Toast.LENGTH_LONG).show();
super.onResume();
}

/**

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;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
if (item.getItemId()==R.id.m_add_record) {

//invoke the AddNewRecord screen using Intent
Intent i = new Intent(getApplicationContext(),
AddNewRecord.class);
startActivity(i);
}
return true;
}

}//end DisplayList class


Now, try compiling and run…
