}

Usage

You can set the XML view as default.

<com.ihaydin.passwordmeter.PasswordMeterView
    android:id="@+id/cvPasswordMeter"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintEnd_toEndOf="@id/etContent"/>

Then let's get the UI by setting the required default values for the UI

strengthView.apply {
    setBarsTintColor(color = android.R.color.darker_gray)
    setCountSize(size = 5)
    setBarRadius(radius = 20)
    setBarWidth(value = 10)
    setBarSpace(value = 6)
    setTextHeight(value = 14)
    setTextPaddingStart(value = 8f)
    setBarHeight(value = 3f)
    setTextFontStyle(font = "fonts/regular.ttf")
}

In the example, there are 3 strengths, weak, medium and strong. To add these levels, let's add them into a list. If you want more options, you can add 4 or more options to the list. NOTE: If you have more than 3 tabs by default, you should increase the number of strength view bars proportionally.

 val states = listOf(
            State(
                text = "Weak",
                color = ContextCompat.getColor(this, android.R.color.holo_red_dark),
                tintSize = 1
            ),
            State(
                text = "Medium",
                color = ContextCompat.getColor(this, android.R.color.holo_orange_light),
                tintSize = 3
            ),
            State(
                text = "Strong",
                color = ContextCompat.getColor(this, android.R.color.holo_green_dark),
                tintSize = 5
            )
        )

        strengthView.setList(states)

Finally, let's define the necessary actions in the listener to listen to the values entered by the user.

etContent.addTextChangedListener(object : TextWatcher {
            override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {

            }

            override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
            }

            override fun afterTextChanged(value: Editable?) {
                value.let {
                    when {
                        it.toString().contains("weak") -> {
                            strengthView.apply {
                                setSelectedIndex(state = 0)
                            }
                        }
                        it.toString().contains("medium") -> {
                            strengthView.apply {
                                setSelectedIndex(state = 1)
                            }
                        }
                        it.toString().contains("strong") -> {
                            strengthView.apply {
                                setSelectedIndex(state = 2)
                            }
                        }
                        else -> {
                            strengthView.apply {
                                setSelectedIndex(state = 0)
                            }
                        }
                    }
                }
            }
        })
