Download

You can download binaries from GitHub's release page

Or use Gradle:
Step 1. Add it in your root build.gradle at the end of repositories:

    allprojects {
        repositories {
            ...
            maven { url "https://jitpack.io" }
        }
    }

Step 2. Add the dependency

    dependencies {
            compile 'com.github.panespanes:ShapeLocker:v1.0.4'
    }


How to Use

Simple use case:

in layout.xml: 

// To create a simple view:
    <com.panes.shapelocker.view.ShapeLocker
        android:id="@+id/sl"
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/darker_gray"
        >

    </com.panes.shapelocker.view.ShapeLocker>

More configurations:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.sp);

        // load a default theme:
        ShapeLockerProperties.with(this).loadLightTheme();
        // or:
        ShapeLocker sl = (ShapeLocker) findViewById(R.id.sl);
        sl.loadLightTheme();


    }


UNSOLVED:

模拟器上运行的bug (真机上运行没影响)
有同学反映模拟器上运行会出现"密码圈绘制不全"的bug, 如图

做了些实验, 真机不会出现这个bug, AVD自带模拟器没有重现, BlueStacks模拟器没有类似情况,
而"靠谱助手","海马玩","逍遥模拟器"等VirtualBox底层的模拟器均重现bug.
猜测是由于VirtualBox的驱动对于安卓UI图形绘制的支持并不全面导致的:
具体原因ShapeLocker对界面刷新做了优化, 响应触摸事件后只重绘被影响区域,
相关代码: 

 Rect invalidateRect = new Rect();
 ...
 invalidateRect.set((int) (left - radius), (int) (top - radius), (int) (right + radius), (int) (bottom + radius));
 ...
 invalidateRect.union((int) (left - radius), (int) (top - radius), (int) (right + radius), (int) (bottom + radius));
 ...
 invalidateRect.set((int) (left - widthOffset), (int) (top - heightOffset), (int) (right + widthOffset), (int) (bottom + heightOffset));
 ...
 invalidate(invalidateRect);

而VirtualBox并不会按照严格按照rect大小重绘区域.
解决办法(真机运行的项目中请不要这样修改, 因为会造成平均34%左右性能损失):
将这部分代码改为

invalidate();

即可.
