Answer 1

NinePointLineView这个类定义一个内部接口类 OnLockReleasedListener和一个该接口类的成员变量，还有一个方法setOnLockReleasedListener(OnLockReleasedListener listener)，
你的ImageLockActivity类来实现这个接口，并设置setOnLockReleasedListener(this);public class NinePointLineView extends View {
    
    OnLockReleasedListener mListener;
   
    
    
    public void setOnLockReleasedListener(OnLockReleasedListener listener) {
        mListener = listener;
    }
    
    public interface OnLockReleasedListener {
        void onLockReleased(boolean released);
    }
}public class ImageLockActivity extends Activity implements        
                                     NinePointLineView.OnLockReleasedListener {    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        NinePointLineView v = new NinePointLineView(this);
        v.setOnLockReleasedListener(this);
        setContentView(v);
        
    }    @Override
    public void onLockReleased(boolean released) {
        //To change body of implemented methods use File | Settings | File Templates.
        if (released) {
            finish();
        }
    }
}

Answer 2

忘了一点就是在finishDraw函数中调用
private void finishDraw() {
    ........
    boolean isLockReleased = /////楼主该你出手了，判断是否解锁成功
    mListener.onLockReleased(isLockReleased);
}
