3.5.3. Setting preferences¶

ABT provides preferences to add new projects for projectwise accounting and manual account code generation.
if project checkbox is checked, new edittext will appear on the screen to add project names.
and if manual account code checkbox is checked, manual account code field will be provided while creating account.
User can also edit organisation details and add/edit/delete project name.
On selecting Master menu >> Preferences, It provides a popup to select any one option from the above two.

3.5.3.1. Preferences¶

Once you create a new organisation and save details of it, ABT asks for setting up project and account code preferences.
The layout is included in res/layout/prefernces.xml.

User can also edit organisation details and add/edit/delete project name.
On selecting Master menu >> Preferences, It provides a popup to select any one option from the above two.

3.5.3.2. Edit organisation details¶

On clicking this option, It will take us to the edit organisation detail page.
This page will display previously saved organisation information.
User can edit these fields if required.
and press Save button to save details in database.
The layout is included in res/layout/org_details.xml and the associated code for saving details is included in src/com/example/gkaakash/orgDetails.java.
To refer these files go to this chapter.

3.5.3.3. Add/Edit/Delete project¶

On slecting this option, It will call a new activity and a new screen appers.
Screen includes a Plus button at the top to add new project names and a list containing project names.
Layout is included in res/layout/add_project.xml.

On selecting any project name from list, it diplays a popup which having two options such as edit or delete project name.
If project has transactions, it can not be deleted.
The associated java code is included in

File src/com/example/gkaakash/addProject.java

The activity is explained below along with code.

It contains the essential and required import like

package com.example.gkaakash;

import java.util.ArrayList;
import java.util.List;
import android.R.color;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.Context;

The activity intializes all the essential parameters and variables.

OnCreate method calls all required methods at load time.

                addProject();

getResultList method used to get the list of all project names and to set it in a listview.

void getResultList(Object[] param){
        projectNameList = new ArrayList();
        projectCodeList = new ArrayList();
        for(Object pn : param)
        {
                Object[] p = (Object[]) pn;
                projectCodeList.add((Integer)p[0]);
                projectNameList.add((String)p[1]); //p[1] is project_name and p[0] is project code
        }
        ltProjectNames.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, projectNameList));
}

Below class is used to delete project name edittext from customised alert dialog.
Gets all the information necessary to delete itself from the constructor.
Deletes itself when the button is pressed.

Below method is used to generate a new project name edittext programatically when plus button is pressed.

public void addButton() {
        //projectTable.setVisibility(TableLayout.VISIBLE);
        TableRow newRow = new TableRow( projectTable.getContext() );
        newRow.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));
        //newRow.addView(child, width, height)

        EditText etdynamic = new EditText(newRow.getContext());
        etdynamic.setText( "" );
        etdynamic.setHint("Tap to enter                              ");
        etdynamic.setWidth(215); //for emulator 215
        etdynamic.setInputType(InputType.TYPE_TEXT_FLAG_CAP_WORDS);
        etdynamic.setId(++rowsSoFar);

        idCount ++;

        //actionButton.setText( "Action: " + ++rowsSoFar );
        Button removeSelfButton = new Button( newRow.getContext() );
        removeSelfButton.setText( "  -  " ); //for tablet ***** add  space

        //removeSelfButton.setBackgroundResource(R.drawable.button_plus_green);
        //removeSelfButton.setBackgroundColor(color)
        // pass on all the information necessary for deletion
        removeSelfButton.setOnClickListener( new RowRemover( projectTable, newRow ));

        newRow.addView(etdynamic);

        newRow.addView( removeSelfButton );
        projectTable.addView(newRow);

}

create a sample alert dialog which can be used all over the page to display validation messages.

public void toastValidationMessage(String message) {
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setMessage(message)
                .setCancelable(false)
                .setPositiveButton("Ok",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {

                            }
                        });

        AlertDialog alert = builder.create();
        alert.show();

}

On pressing Back button of device, go to the master menu page.

@Override
public void onBackPressed() {
        Intent intent = new Intent(getApplicationContext(), menu.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(intent);
}
