Requirements
Android 4.3+
Installation
Add edit your build.gradle file
allprojects {
repositories {
...
maven {
url 'https://jitpack.io'
}
}
}
Then add as dependency to yout app/build.gradle
dependencies {
...

Usage
This library let you to create forms and add them in a LinearLayout. If you want to scroll this linear layout remember to add it inside a ScrollView. Here is an example:
LinearLayout mLinearLayout; FormBuilder formBuilder;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setContentView(R.layout.activity_main);
mLinearLayout = (LinearLayout) findViewById(R.id.linearLayout);
formBuilder = new FormBuilder(this, mLinearLayout);
List<FormObject> formObjects = new ArrayList<FormObject>();
formObjects.add(new FormElement()
.setTag("text") // Tag is necessary in order to retrieve values
.setHint("text") // Hint is the placeholder of the generated EditText
.setType(FormElement.Type.TEXT) // Type of form
.setEnabled(true) // Enable or not the EditText (default true)
.setRequired(true) // For validation purpose (default false)
);
formObjects.add(new FormElement().setTag("email").setHint("email").setType(FormElement.Type.EMAIL));
formObjects.add(new FormElement().setTag("phone").setHint("phone").setType(FormElement.Type.PHONE));
formObjects.add(new FormButton()
.setTitle("Go!")
.setBackgroundColor(Color.RED)
.setTextColor(Color.WHITE)
.setRunnable(new Runnable() {
@Override
public void run() {
boolean isValid = formBuilder.validate();
Log.i("Forms", formBuilder.formMap.toString());
}
}
)
);
formBuilder.build(formObjects);
}
Details
It's possible to add different type of form.
FormBuilder formBuilder = new FormBuilder(this, mLinearLayout);
List<FormObject> formObjects = new ArrayList<FormObject>();
// Header formObjects.add(new FormHeader().setTitle("Hello"));
// Simple text formObjects.add(new FormElement().setTag("text").setHint("text").setType(FormElement.Type.TEXT));
// Simple text without placeholder animation (for long text for example) formObjects.add(new FormElement().setTag("view").setHint("view").setType(FormElement.Type.TEXTVIEW));
// E-mail formObjects.add(new FormElement().setTag("email").setHint("email").setType(FormElement.Type.EMAIL));
// Phone formObjects.add(new FormElement().setTag("phone").setHint("phone").setType(FormElement.Type.PHONE));
// Number formObjects.add(new FormElement().setTag("number").setHint("number").setType(FormElement.Type.NUMBER));
// Password formObjects.add(new FormElement().setTag("password").setHint("password").setType(FormElement.Type.PASSWORD));
// Postal code formObjects.add(new FormElement().setTag("zip").setHint("zip").setType(FormElement.Type.ZIP));
// Date type: it's possible to set date format (default is "ddMMyyyy") formObjects.add(new FormElement().setTag("date").setHint("date").setType(FormElement.Type.DATE).setDateFormat("dd-MM-yyyy"));
// Time type: it's possible to set time format (default is "HH:mm:ss") formObjects.add(new FormElement().setTag("time").setHint("time").setType(FormElement.Type.TIME).setTimeFormat("HH:mm"));
// Single selection List<String> arrayList = new ArrayList<String>();
arrayList.add("hello");
arrayList.add("hi");
arrayList.add("goodmorning");
formObjects.add(new FormElement().setTag("single").setHint("single").setType(FormElement.Type.SELECTION).setOptions(arrayList));
// Multiple selection List<String> arrayList2 = new ArrayList<String>();
arrayList2.add("hello2");
arrayList2.add("hi2");
arrayList2.add("goodmorning2");
formObjects.add(new FormElement().setTag("multiple").setHint("multiple").setType(FormElement.Type.MULTIPLE_SELECTION).setOptions(arrayList2));
formBuilder.build(formObjects);
// Button: it's possible to set background color, text color and a runnable that will be executed once the button is pressed. formObjects.add(new FormButton()
.setTitle("Go!")
.setBackgroundColor(Color.RED)
.setTextColor(Color.WHITE)
.setParams(layoutParams)
.setRunnable(new Runnable() {
@Override
public void run() {
Log.i("Forms", formBuilder.formMap.toString());
}
}
)
);
Retrieve values
Values inserted are saved inside a map of the object FormBuilder, using tags as key.
String textValue = formBuilder.formMap.get("text").getValue();
Layout
Every object inside a form has a params attribute which represent LayoutParams of the generated form.
// This will create a form of type TEXTVIEW with a height of 320. final FormElement formElement = new FormElement().setTag("view")
.setHint("view")
.setType(FormElement.Type.TEXTVIEW)
.setParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 320));
Validation
To make a validation simply call
boolean isValid = formBuilder.validate();
This will show an error on all forms that has been set as required.
It's possible to change error content on each form element.
formObjects.add(new FormElement()
.setTag("text")
.setHint("text")
.setType(FormElement.Type.TEXT)
.setErrorMessage("You can learn from this error"));
Every form element can accept a customized code for its validation.
final FormElement formElement = new FormElement().setTag("view").setHint("view").setType(FormElement.Type.TEXTVIEW));
formElement.setFormValidation(new FormValidation() {
@Override
public boolean validate() {
return formElement.getValue().length() > 5;
}
}
).setErrorMessage("Too short");
TODO
- Add different types of errors.
- Add SPINNER type.
- Testing.
