  • PinEntryEditText which supports text animating in.
  • Lets you specify any unicode character to be used as a mask for input.
  • Specify drawable as the foreground/background.

Usage

Below is a fast guide to getting started. However, if you need to read about these widgets in details. Read more about PinEntryEditText.

NOTE: Make sure jcenter() is one of the repositories mentioned in your build.gradle. This used to be the default repository for Android but since then has changed the google() This needs to be set in your top level build.gradle: <project root>/build.gradle

buildscript {
    repositories {
        jcenter()
        ...
    }
    ...
}

STEP-1

Gradle

Jetpack support in version 2.0 Download:

dependencies {
    implementation ('com.alimuzaffar.lib:pinentryedittext:2.0.6') {
        // Exclude is only needed if you already have
        // androidx.appcompat as a dependency in your app.
        exclude group: 'androidx.appcompat', module: 'appcompat'
    }
}

If you don't use Jetpack, use version 1.3.X Download

dependencies {
    implementation ('com.alimuzaffar.lib:pinentryedittext:1.3.10') {
        // Exclude is only needed if you already have
        // any of the following as a dependency in your project.
        exclude group: 'com.android.support', module: 'support-v4'
        exclude group: 'com.android.support', module: 'appcompat-v7'
        exclude group: 'com.android.support', module: 'support-v13'
    }
}

Note: You don't need to exclude all the support groups. However, it's a good idea to do this as your code is likely to use a different version from the library.

STEP-2

Setup PinEntryEditText in your layout

<com.alimuzaffar.lib.pin.PinEntryEditText
    android:id="@+id/txt_pin_entry"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:cursorVisible="false" //recommended
    android:digits="1234567890"
    android:inputType="number"
    android:maxLength="4" //required
    android:textIsSelectable="false" //recommended
    android:textSize="20sp"
    app:pinBackgroundDrawable="@drawable/bg_pin" //optional, use your own pin char background
    app:pinAnimationType="popIn|fromBottom|none" //optional, default popIn
	app:pinCharacterMask="*" //optional, default bullet
	app:pinSingleCharHint="#" //optional, hint for each characters
	app:pinTextBottomPadding="@dimen/space" //optional, space between character and bottom line.
	app:pinLineStroke="2dp" //the stroke (height) of the bottom line by default.
	app:pinLineStrokeSelected="4dp" //the stroke (height) of the bottom line when field is focused.
	app:pinBackgroundIsSquare="true|false" //optional, if you want the background drawable to be a square or circle width of each digit will be set to match the height of the widget.
    app:pinLineColors="@color/pin_line_colors" //optional
    android:layoutDirection="ltr|rtl"
    />

Listen for pin entry

final PinEntryEditText pinEntry = (PinEntryEditText) findViewById(R.id.txt_pin_entry);
if (pinEntry != null) {
    pinEntry.setOnPinEnteredListener(new PinEntryEditText.OnPinEnteredListener() {
        @Override
        public void onPinEntered(CharSequence str) {
            if (str.toString().equals("1234")) {
                Toast.makeText(AnimatedEditTextWidgetsActivity.this, "SUCCESS", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(AnimatedEditTextWidgetsActivity.this, "FAIL", Toast.LENGTH_SHORT).show();
                pinEntry.setText(null);
            }
        }
    });
}

Use your own Drawable as a pin character background

You can use your own drawable for the pin entry background by specifying the app:pinBackgroundDrawable attribute in the xml. If you want to specify the empty and filled states using your background drawable you can set the textColor to transparent and setup your drawable as follows:

<!--
    Please look at the sample app's bg_pin.xml
    or bg_pin_round.xml for all available options
-->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Space contains text -->
    <item android:state_focused="true" android:state_checked="true">
        <shape android:shape="rectangle">
            <solid android:color="@android:color/holo_green_light"/>
        </shape>
    </item>
    <!--Space is the next space for character input -->
    <item android:state_focused="true" android:state_selected="true">
        <shape android:shape="rectangle">
            <solid android:color="@android:color/holo_blue_bright"/>
        </shape>
    </item>
    <!-- PinEntryEditText is focused -->
    <item android:state_focused="true">
        <shape android:shape="rectangle">
            <solid android:color="@android:color/white"/>
        </shape>
    </item>
    <!-- PinEntryEditText is not focused -->
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@android:color/darker_gray"/>
        </shape>
    </item>
</selector>

Note that in this setup, the size of the drawable will be determined by the textSize and and the pinTextBottomPadding which is the space between the character and the line below (or the bottom of the pinBackgroundDrawable). For good measure, set pinAnimationType to none as well.

Effects :

  1. PopIn (default)
  2. Bottom Up
