Form-Master

Easily build big and bigger forms with minimal effort

This library aids in building bigger forms on-the-fly. Forms with large number of elements can easily be added programmatically within a few minutes.

Features

• Easily build big and bigger forms with minimal effort
• Fast color change as needed

Installation

Add this in your app's build.gradle file:

compile 'me.riddhimanadib.form-master:form-master:1.1.0'

How to use

1. Add a Recyclerview anywhere in the layout where you want your list to be shown (If confused, look at the examples in this repo).

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:id="@+id/recyclerView"
        android:descendantFocusability="beforeDescendants" />

</LinearLayout>

2. Add the Form Elements programmatically in your activity

// initialize variables
mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView);
mFormBuilder = new FormBuildHelper(this, mRecyclerView);

// declare form elements
FormHeader header = FormHeader.createInstance("Personal Info");
FormElementTextEmail element = FormElementTextEmail.createInstance().setTitle("Email").setHint("Enter Email");
        
// add them in a list
List<FormObject> formItems = new ArrayList<>();
formItems.add(header);
formItems.add(element);

// build and display the form
mFormBuilder.addFormElements(formItems);
mFormBuilder.refreshView();

3. Now build and run!!

Reference

Item Definition

Header:

FormHeader header = FormHeader.createInstance("Personal Info");

Regular Elements:

General object format

<Class> element = <Class>.createInstance()
    .setTag(101123151) // optional tag to uniquely identify the elemnt for later use
    .setType(FormElement.TYPE_PICKER_MULTI_CHECKBOX) // setting input type
    .setTitle("Pick your favourite fruit") // setting title
    .setValue("Banana") // setting value of the field, if any
    .setOptions(fruits) // setting pickable options, if any
    .setHint("e.g. banana, guava etc") // setting hints, if any
    .setRequired(false); // marking if the form element is required to be filled to make the form valid, include if needed

Samples:

// email input
FormElementTextEmail element = FormElementTextEmail.createInstance().setTitle("Email").setHint("Enter Email");

// phone number input
FormElementTextPhone element = FormElementTextPhone.createInstance().setTitle("Phone").setValue("+8801712345678");

// single line text input
FormElementTextSingleLine element = FormElementTextSingleLine.createInstance().setTitle("Location").setValue("Dhaka");

// multi line text input (default 4)
FormElementTextMultiLine element = FormElementTextMultiLine.createInstance().setTitle("Address");

// number element input
FormElementTextNumber element = FormElementTextNumber.createInstance().setTitle("Zip Code").setValue("1000");

// date picker input
FormElementPickerDate element = FormElementPickerDate.createInstance().setTitle("Date").setDateFormat("MMM dd, yyyy");

// time picker input
FormElementPickerTime element = FormElementPickerTime.createInstance().setTitle("Time").setTimeFormat("KK hh");

// password input
FormElementTextPassword element = FormElementTextPassword.createInstance().setTitle("Password").setValue("abcd1234");

// switch input
FormElementSwitch element = FormElementSwitch.createInstance().setTitle("Frozen?").setSwitchTexts("Yes", "No");

// single item picker input
List<String> fruits = new ArrayList<>();
fruits.add("Banana");
fruits.add("Orange");
fruits.add("Mango");
fruits.add("Guava");
FormElementPickerSingle element = FormElementPickerSingle.createInstance().setTitle("Single Item").setOptions(fruits).setPickerTitle("Pick any item");

// multiple items picker input
List<String> fruits = new ArrayList<>();
fruits.add("Banana");
fruits.add("Orange");
fruits.add("Mango");
fruits.add("Guava");
FormElementPickerMulti element = FormElementPickerMulti.createInstance().setTitle("Multi Items").setOptions(fruits).setPickerTitle("Pick one or more").setNegativeText("reset");

Set form element value change listener to get changed value instantly

While creating new instance of FormBuildHelper, add a listener in the constructor

Have a look at the example code for details

FormBuildHelper mFormBuilder = new FormBuildHelper(this, mRecyclerView, new OnFormElementValueChangedListener() {
    @Override
    public void onValueChanged(FormElement formElement) {
        // do anything here with formElement.getValue()
    }
}
);

Set unique tags for form elements (for later value retrieval)

Just add a unique tag for the element

FormElement element = FormElement.createInstance()
    .setTag(2149) // unique tag number to identify this element
    .setType(FormElement.TYPE_PICKER_MULTI_CHECKBOX)
    .setTitle("Pick your favourite fruit");

Get value for unique form elements

Use the unique tag assigned earlier to retrieve value (See examples in this repo)

FormElement targetElement = mFormBuilder.getFormElement(2149);
String targetValue = targetElement.getValue();

Check if form is valid

Use this method if you need to check whether the required elements of the form is completed

mFormBuilder.isValidForm(); // returns boolean whether the form is valid or not

Form accent color change

If you want to change the colors, just override the colors in your colors.xml file:

<color name="colorFormMasterHeaderBackground">#DDDDDD</color>
<color name="colorFormMasterHeaderText">#000000</color>
<color name="colorFormMasterElementBackground">#FFFFFF</color>
<color name="colorFormMasterElementTextTitle">#222222</color>
<color name="colorFormMasterElementTextValue">#000000</color>
<color name="colorFormMasterDivider">#DDDDDD</color>

Form UI change

If you want to change how the forms look, just override the layout xml named form_element.xml and/or form_element_header.xml in your project.

Just make sure to keep the ID name same as it is in the library for the components.

android:id="@+id/formElementTitle"
android:id="@+id/formElementValue"
