1. Basic

Add com.developer.mtextfield.TextFieldBoxes that contains a com.developer.mtextfield.ExtendedEditText to your layout:

...
<com.developer.mtextfield.TextFieldBoxes
    android:id="@+id/text_field_boxes"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:labelText="Label">

    <com.developer.mtextfield.ExtendedEditText
        android:id="@+id/extended_edit_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

</com.developer.mtextfield.TextFieldBoxes>
...

2. Enable / Disable

app:enabled in xml or setEnabled(boolean enabled) in Java.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:enabled="false"
    >

3. Helper Text & Error Text

NOTE: setting helper or error text to anything not empty will make the bottom view (which contains the helper label) visible and increase the height of the TextFieldBoxes. So if you want to always keep the bottom view visible (height increased), set the helper text to " " when there should be nothing.

helper text: app:helperText in xml or setHelperText(String helperText) in Java.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:helperText="Helper is here"
    >

error text: setError(String errorText, boolean giveFocus) in Java.

Param giveFocus determines whether the field will gain focus when set error on. If true, the field gains focus immediately.

NOTE: Error will be removed when the text changes (input or delete).

setError("Error message");

4. Prefix & Suffix

! NOTE: Prifix and Suffix attributes should be set to ExtendedEditText.

Use app:prefix in xml or setPrefix(String prefix) in Java to set the unselectable prefix text at the start of the field.

Use app:suffix in xml or setSuffix(String suffix) in Java to set the unselectable suffix text at the end of the field.

<com.developer.mtextfield.ExtendedEditText
    ...
    app:prefix="$ "
    >

<com.developer.mtextfield.ExtendedEditText
    ...
    app:suffix="\@gmail.com"
    >

5. Max & Min Characters

NOTE: setting max or min character will make the bottom view (which contains the counter label) visible and increase the height of the TextFieldBoxes.

Use app:maxCharacters in xml or setMaxCharacters(int maxCharacters) in java code to set the max characters count. Use removeMaxCharacters() in java code to remove the limit.

Use app:minCharacters in xml or setMinCharacters(int minCharacters) in java code to set the min characters count. Use removeMinCharacters() in java code to remove the limit.

The color of the bottom line will turn to errorColor (red by default) when exceeding max or min characters limit. 0, as default, means no max or min characters limit.

NOTE: Space and line feed will NOT count.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:maxCharacters="10"
    app:minCharacters="5"
    >

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:maxCharacters="5"
    >

6. Icon Signifier

Use app:iconSignifier in xml or setIconSignifier(Int resourceID) to set the icon that is shown in front of the TextFieldBoxes if you want there to be one.

You can use setIsResponsiveIconColor(boolean isrResponsiveIconColor) in Java code to set whether the icon will change its color when gaining or losing focus as the label text and the bottomLine do. NOTE that if true, the icon's color will always be HighlightColor (the same as the bottomLine) that will turn gray when losing focus. If false, the icon will always be in primaryColor.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:iconSignifier="@drawable/ic_vpn_key_black_24dp"
    >

7. End Icon

Use app:endIcon in xml or setEndIcon(Int resourceID) to set the icon of the ImageButton that is shown at the end of the field if you want there to be one.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:endIcon="@drawable/ic_mic_black_24dp"
    >

To make it useful (trigger voice input, dropdown event), you would like to use getEndIconImageButton() in Java code to set, for example, what will happen when it's clicked (with .setOnClickListener()), or anything else you want.

final TextFieldBoxes textFieldBoxes = findViewById(R.id.text_field_boxes);
textFieldBoxes.getEndIconImageButton().setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        // What you want to do when it's clicked
    }
});

8. Clear Button

Use app:hasClearButton in xml or setHasClearButton(boolean hasClearButton) to set whether to show the clear button.

If true, a clear button will be shown at the end when there are characters (ANY character) entered in the field.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:hasClearButton="true"
    >

9. Custom Colors

Primary Color will be used for the color of the underline, the floating label text and the icon signifier when HAVING focus. You can use app:primaryColor in xml or setPrimaryColor(int colorRes) in Java. Current theme Primary Color by default.

Secondary Color will be used for the color of the underline, the floating label text and the icon signifier when NOT HAVING focus. You can use app:secondaryColor in xml or setSecondaryColor(int colorRes) in Java. Current theme textColorTertiary by default.

Error Color will be used for the color that indicates error (e.g. exceeding max characters, setError()). You can use app:errorColor in xml or setErrorColor(int colorRes) in Java. A400 red by default.

Helper Text Color will be used for the color of the helper text. You can use app:textHelperColor in xml or setHelperTextColor(int colorRes) in Java. 54% black by default.

Panel Background Color will be used for the color of panel at the back. You can use app:panelBackgroundColor in xml or setPanelBackgroundColor(int colorRes) in Java. 6% black by default. NOTE that the default color, as in the guideline, is the black (#000000) color with the transparency of 6%, so when you're customizing and want it to still be transparent you have to set a color with transparency.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:primaryColor="#1B5E20"
    app:errorColor="#ddaa00"
    app:textHelperColor="#795548"
    app:panelBackgroundColor="#ffe8e8"
    >

Ripple Color will be used for the ripple effect when the view is clicked. You can customize it in your styles.xml by adding the following:

<style name="TextFieldBoxes">
    <item name="android:colorControlHighlight" tools:targetApi="lollipop">YOUR_COLOR</item>
</style>

then set this as the theme for your TextFieldBoxes:

<com.developer.mtextfield.TextFieldBoxes
    ...
    android:theme="@style/TextFieldBoxes"
    >

10. Dense Spacing

You can make the layout compact by using a dense verticle spacing to improve user experience in some cases.

Use app:useDenseSpacing in xml or setUseDenseSpacing(boolean useDenseSpacing) to set whether the field uses a dense spacing between its elements.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:useDenseSpacing="true"
    >

11. Always Show Hint

Sometimes you may want the label and the hint to show different messages, but need the hint to always be shown (instead being blocked by the label when losing focus).

Use app:alwaysShowHint in xml or setAlwaysShowHint(boolean alwaysShowHint) to set whether the label is fixed at top when there's a hint in the EditText.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:alwaysShowHint="true"
    >

12. Text Change Watcher

It is strongly recommanded to use setSimpleTextChangeWatcher() to listen the event of changing text instead of addTextChangedListener().

This has the following advantages:

1. You don't need to implement beforeTextChanged() and onTextChanged() method when unnecessary.
2. Avoids potential unexpected behavior, by guaranteeing your code to run after the default processes (remove error, update counter text, etc.) are finished.
3. When the view is recycled, no manual remove call is needed.

e.g.

final TextFieldBoxes textFieldBoxes = findViewById(R.id.text_field_boxes);
textFieldBoxes.setSimpleTextChangeWatcher(new SimpleTextChangedWatcher() {
    @Override
    public void onTextChanged(String theNewText, boolean isError) {
        // What you want to do when text changes
    }
});

13. Dark Theme

MTextField use the color attributes within the current theme and will automatically change its color to fit the dark theme without additional settings.

14. Manual Validate Error

By default, the error state of the field is validated each time the text changes and also at time of construction. This means a field with a minimum length requirement will start in the Error state.

Setting app:manualValidateError to true will make the field validate error only when validate() is called.

<com.developer.mtextfield.TextFieldBoxes
    ...
    app:manualValidateError="true"
    >

final TextFieldBoxes textFieldBoxes = findViewById(R.id.text_field_boxes);
// The error state will only be updated when this is called
textFieldBoxes.validate()
