18 Jellys

JTB provides 18 kinds of jelly types to show different effects of thumb. You can use different jelly types in xml or by setJelly() method.
Use in xml:

<com.nightonke.jellytogglebutton.JellyToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:jtbJelly="itself"
    />

Use in setter:

jtb.setJelly(Jelly.ITSELF);

app:jtbJelly=""	setJelly()	Effect
itself	ITSELF
lazy_tremble_head_fatty	LAZY_TREMBLE_HEAD_FATTY
lazy_tremble_head_slim_jim	LAZY_TREMBLE_HEAD_SLIM_JIM
lazy_tremble_tail_fatty	LAZY_TREMBLE_TAIL_FATTY
lazy_tremble_tail_slim_jim	LAZY_TREMBLE_TAIL_SLIM_JIM
lazy_tremble_body_fatty	LAZY_TREMBLE_BODY_FATTY
lazy_tremble_body_slim_jim	LAZY_TREMBLE_BODY_SLIM_JIM
lazy_stiff_fatty	LAZY_STIFF_FATTY
lazy_stiff_slim_jim	LAZY_STIFF_SLIM_JIM
active_tremble_head_fatty	ACTIVE_TREMBLE_HEAD_FATTY
active_tremble_head_slim_jim	ACTIVE_TREMBLE_HEAD_SLIM_JIM
active_tremble_tail_fatty	ACTIVE_TREMBLE_TAIL_FATTY
active_tremble_tail_slim_jim	ACTIVE_TREMBLE_TAIL_SLIM_JIM
active_tremble_body_fatty	ACTIVE_TREMBLE_BODY_FATTY
active_tremble_body_slim_jim	ACTIVE_TREMBLE_BODY_SLIM_JIM
active_stiff_fatty	ACTIVE_STIFF_FATTY
active_stiff_slim_jim	ACTIVE_STIFF_SLIM_JIM
random	RANDOM	All Above

Notice that random type will change the jelly among the other 17 types randomly.

Define Your Jelly

You can define you own jelly easily. But you need sometime to understand what happens in the source code of Jelly enum. All the jelly type are the sub types of JellyStyle.class.
To extend the abstract class, you have to override 3 methods:

public class MyJelly extends JellyStyle {

    @Override
    public void changeShape(PointWithHorizontalPoints p1, PointWithVerticalPoints p2, PointWithHorizontalPoints p3, PointWithVerticalPoints p4, float stretchDistance, float bezierControlValue, float bezierScaleRatioValue, float thumbRadius, float process, State state) {
        // Change the shape of the thumb.
        // Notice that we use 12 points to form 4 bezier lines to draw the thumb.
        // We can control the shape of the thumb by controling the 12 points.
    }

    @Override
    public void changeOffset(PointWithHorizontalPoints p1, PointWithVerticalPoints p2, PointWithHorizontalPoints p3, PointWithVerticalPoints p4, float totalLength, float extractLength, float process, State state, EaseType easeType) {
        // Change the offset of the thumb.
    }

    @Override
    public float extractLength(float stretchDistance, float bezierControlValue, float bezierScaleRatioValue, float thumbRadius) {
        // Return the extract length.
    }
}

After this, use setCustomJelly() to set your custom jelly. Notice that if you don't want to use the custom any more, you have to use removeCustomJelly() to reset.

Ease Types

Ease types are used to set the effect of movement of the thumb.

Of course you can use linear function. You can find all the ease enums here.
It's very convenient to use ease types in xml:

<com.nightonke.jellytogglebutton.JellyToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:jtbEaseType="ease_in_out_circ"
    />

Or use setter:

jtb.setEaseType(EaseType.EaseInOutCirc);

Check all the ease types below.

app:jtbEaseType=""	setEaseType()
ease_in_sine	EaseType.EaseInSine
ease_out_sine	EaseType.EaseOutSine
ease_in_out_sine	EaseType.EaseInOutSine
ease_in_quad	EaseType.EaseInQuad
ease_out_quad	EaseType.EaseOutQuad
ease_in_out_quad	EaseType.EaseInOutQuad
ease_in_cubic	EaseType.EaseInCubic
ease_out_cubic	EaseType.EaseOutCubic
ease_in_out_cubic	EaseType.EaseInOutCubic
ease_in_quart	EaseType.EaseInQuart
ease_out_quart	EaseType.EaseOutQuart
ease_in_out_quart	EaseType.EaseInOutQuart
ease_in_quint	EaseType.EaseInQuint
ease_out_quint	EaseType.EaseOutQuint
ease_in_out_quint	EaseType.EaseInOutQuint
ease_in_expo	EaseType.EaseInExpo
ease_out_expo	EaseType.EaseOutExpo
ease_in_out_expo	EaseType.EaseInOutExpo
ease_in_circ	EaseType.EaseInCirc
ease_out_circ	EaseType.EaseOutCirc
ease_in_out_circ	EaseType.EaseInOutCirc
ease_in_back	EaseType.EaseInBack
ease_out_back	EaseType.EaseOutBack
ease_in_out_back	EaseType.EaseInOutBack
ease_in_elastic	EaseType.EaseInElastic
ease_out_elastic	EaseType.EaseOutElastic
ease_in_out_elastic	EaseType.EaseInOutElastic
ease_in_bounce	EaseType.EaseInBounce
ease_out_bounce	EaseType.EaseOutBounce
ease_in_out_bounce	EaseType.EaseInOutBounce
linear	EaseType.Linear

SetCheck Methods

You can control the state of the JTB of the following methods:
(When the thumb is to the end of right, we say the JTB is checked)

isChecked() Whether the JTB is checked.
setChecked(boolean checked) Set the JTB to checked or not with animation. If the listener has been set, it will be called.
setChecked(boolean checked, boolean callListener) Same as above, but you can choose whether call the listener(if not null).
setCheckedImmediately(boolean checked) Set the JTB to checked or not immediately without animation. This method will call the listener if it's not null.
setCheckedImmediately(boolean checked, boolean callListener) Same as above, and you can choose whether call the listener.
toggle() Change the JTB to another state and call the listener.
toggle(boolean callListener) Same as above and you can choose whether call the listener.
toggleImmediately() Toggle, without animation and call the listener.
toggleImmediately(boolean callListener) Toggle, without animation and you can choose not to call the listener.

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:jtbLeftBackgroundColor="@android:color/black"
    app:jtbRightBackgroundColor="@android:color/white"
    app:jtbLeftThumbColor="@android:color/white"
    app:jtbRightThumbColor="@android:color/black"
    app:jtbLeftTextColor="@android:color/black"
    app:jtbRightTextColor="@android:color/white"
    />

ColorChangeType

There are 2 types to perform the color changing. Use setColorChangeType(ColorChangeType colorChangeType) to select ColorChangeType.RGB or ColorChangeType.HSV or set it in xml:

<com.nightonke.jellytogglebutton.JellyToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:jtbColorChangeType="hsv"
    />

For more information, check here.

Fonts

Use setLeftTextTypeface(Typeface typeface) and setLeftTextTypeface(String typefaceString) to set the typeface of the left text. Notice that the typefaceString is in the assets directory. Similarly, use setRightTextTypeface(Typeface typeface) and setRightTextTypeface(String typefaceString) to set the typeface of the right text.
Or in xml:

<com.nightonke.jellytogglebutton.JellyToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:jtbLeftTextTypeface="fonts/Lato-Hairline.ttf"
    app:jtbRightTextTypeface="fonts/Lato-Hairline.ttf"
    />

Duration

Use setDuration(int duration) to set the duration when the thumb is animating(in ms). The default value is 1000(ms).
Or in xml:

<com.nightonke.jellytogglebutton.JellyToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:jtbDuration="1000"
    />

Text, Text Size and Margins

Use setLeftText(String text) , setLeftTextRes(int res) , setRightText(String text) , setRightTextRes(int res) , setText(String leftText, String rightText) and setTextRes(int leftRes, int rightRes) to set the text.
Use setTextSize(int textSize) and setTextSizeRes(int res) to set the text size.
Use setTextMarginLeft(float margin) and setTextMarginLeftRes(int res) to set the margin between the left text and the left-end of background.
Use setTextMarginRight(float margin) and setTextMarginRightRes(int res) to set the margin between the right text and the right-end of background.
Use setTextMarginTop(float margin) and setTextMarginTopRes(int res) to set the margin between the text and the top of background.
Use setTextMarginBottom(float margin) and setTextMarginBottomRes(int res) to set the margin between the text and the bottom of background.
Use setTextMarginCenter(float margin) and setTextMarginCenterRes(int res) to set the margin between the left text and the right text.

Or in xml:

<com.nightonke.jellytogglebutton.JellyToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:jtbLeftText="Male"
    app:jtbRightText="Female"
    app:jtbLeftTextSize="12sp"
    app:jtbRightTextSize="12sp"
    app:jtbTextMarginLeft="2dp"
    app:jtbTextMarginRight="2dp"
    app:jtbTextMarginBottom="2dp"
    app:jtbTextMarginTop="2dp"
    app:jtbTextMarginCenter="4dp"
    />

Draggable

If you want to forbid user to drag the JTB, just call setDraggable(boolean draggable) to false.
Or in xml:

<com.nightonke.jellytogglebutton.JellyToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:jtbDraggable="false"
    />

Listener

JTB use OnStateChangeListener to detech all the events of itself.

jtb.setOnStateChangeListener(new JellyToggleButton.OnStateChangeListener() {
    @Override
    public void onStateChange(float process, State state, JellyToggleButton jtb) {
        // process - current process of JTB, between [0, 1]
        // state   - current state of JTB, it is one of State.LEFT, State.LEFT_TO_RIGHT, State.RIGHT and State.RIGHT_TO_LEFT
        // jtb     - the JTB
    }
});

For example, if you want to detech when JTB is open or close(open means the thumb moves to the end of right):

@Override
public void onStateChange(float process, State state, JellyToggleButton jbt) {
    if (state.equals(State.LEFT)) {
        if (lastToast != null) lastToast.cancel();
        lastToast = Toast.makeText(this, "Left!", Toast.LENGTH_SHORT);
        lastToast.show();
    }
    if (state.equals(State.RIGHT)) {
        if (lastToast != null) lastToast.cancel();
        lastToast = Toast.makeText(this, "Right!", Toast.LENGTH_SHORT);
        lastToast.show();
    }
}

When the thumb is move to same state, for instance, you drag the thumb just a little bit and then let it go and the thumb will smoothly move to it's last state(left or right). You can use setMoveToSameStateCallListener(boolean callListener) to select whether call listener when the above situation happens.
Or in xml:

<com.nightonke.jellytogglebutton.JellyToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:jtbMoveToSameStateCallListener="true"
    />

Other Methods

There are some methods to modify some useless values. You can use them to fine-tone the JTB.

setTouchMoveRatioValue(float ratio) Set the ratio of distance of dragging to distance of the thumb-movement.
setBezierControlValue(float value) and setBezierControlValueRes(int res) Set the Bezier control value.
setStretchDistanceRatioValue(float value) Set the ratio of thumb-radius to the stretch distance.
setBezierScaleRatioValue(float value) and setBezierScaleRatioValueRes(int res) Set the Bezier scale control value.
