超实用的Android手势锁制作实例教程_Android

今天偶遇以github上gesturelock关于手势锁的一个例子（有兴趣的去搜索下看看），于是下载下来研究，无奈基本没有注释，代码上存在一些问题(当设置gravity=center_vertical无法进行手势选择，无意中发现的)，于是借鉴这位仁兄的代码，自己重写写了一个，修复了一些问题，加入一些基本的自定义属性，在此先感谢这位兄弟~。
先上图，默认效果图：

当然可以自定义数量啊，颜色神马的，自定义效果图：

如果你有艺术细胞，可以给我推荐几个颜色，无奈个人审美有问题~

1、整体思路
a、自定义了一个RelativeLayout(GestureLockViewGroup)在里面会根据传入的每行的个数，生成多个GestureLockView（就是上面一个个小圈圈），然后会自动进行布局，里面的宽度，间距，内圆的直径，箭头的大小神马的都是百分比实现的，所以大胆的设置你喜欢的个数，只要你没有密集恐惧症~
b、GestureLockView有三个状态，没有手指触碰、手指触碰、和手指抬起，会根据这三个状态绘制不同的效果，以及抬起时的小箭头需要旋转的角度，会根据用户选择的GestureLockView，进行计算，在GestureLockViewGroup为每个GestureLockView设置
c、GestureLockViewGroup主要就是判断用户ACTION_MOVE，ACTION_DOWN ， ACTION_UP时改变选中的GestureLockView的状态，并且记录下来，提供一定的回调。
下面开始看代码：

2、声明一些用户可以设置的属性：

<?xml version="1.0" encoding="utf-8"?>
<resources> 

  <attr name="color_no_finger_inner_circle" format="color" />
  <attr name="color_no_finger_outer_circle" format="color" />
  <attr name="color_finger_on" format="color" />
  <attr name="color_finger_up" format="color" />
  <attr name="count" format="integer" />
  <attr name="tryTimes" format="integer" /> 

  <declare-styleable name="GestureLockViewGroup">
    <attr name="color_no_finger_inner_circle" />
    <attr name="color_no_finger_outer_circle" />
    <attr name="color_finger_on" />
    <attr name="color_finger_up" />
    <attr name="count" />
    <attr name="tryTimes" />
  </declare-styleable> 

</resources> 

用户可以用过在xml文件中设置这些属性，改变外观，最多尝试次数以及数量等。

3、GestureLockView

package com.zhy.zhy_gesturelockview.view; 

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Paint.Style;

   */
  private Mode mCurrentStatus = Mode.STATUS_NO_FINGER;

  private int mColorNoFingerInner;
  private int mColorNoFingerOutter;
  private int mColorFingerOn;
  private int mColorFingerUp; 

  public GestureLockView(Context context , int colorNoFingerInner , int colorNoFingerOutter , int colorFingerOn , int colorFingerUp )
  {
    super(context);
    this.mColorNoFingerInner = colorNoFingerInner;

  } 

  @Override
  protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
  {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec); 

    mWidth = MeasureSpec.getSize(widthMeasureSpec);
    mHeight = MeasureSpec.getSize(heightMeasureSpec); 

    // 取长和宽中的小值
    mWidth = mWidth < mHeight ? mWidth : mHeight;
    mRadius = mCenterX = mCenterY = mWidth / 2;
    mRadius -= mStrokeWidth / 2; 

    // 绘制三角形，初始时是个默认箭头朝上的一个等腰三角形，用户绘制结束后，根据由两个GestureLockView决定需要旋转多少度
    float mArrowLength = mWidth / 2 * mArrowRate;
    mArrowPath.moveTo(mWidth / 2, mStrokeWidth + 2);
    mArrowPath.lineTo(mWidth / 2 - mArrowLength, mStrokeWidth + 2
        + mArrowLength);
    mArrowPath.lineTo(mWidth / 2 + mArrowLength, mStrokeWidth + 2
        + mArrowLength);
    mArrowPath.close();
    mArrowPath.setFillType(Path.FillType.WINDING); 

  } 

  @Override
  protected void onDraw(Canvas canvas)
  { 

    switch (mCurrentStatus)
    {
    case STATUS_FINGER_ON: 

      // 绘制外圆
      mPaint.setStyle(Style.STROKE);
      mPaint.setColor(mColorFingerOn);
      mPaint.setStrokeWidth(2);

      break;
    case STATUS_FINGER_UP:
      // 绘制外圆
      mPaint.setColor(mColorFingerUp);
      mPaint.setStyle(Style.STROKE);
      mPaint.setStrokeWidth(2);
      canvas.drawCircle(mCenterX, mCenterY, mRadius, mPaint);
      // 绘制内圆
      mPaint.setStyle(Style.FILL);
      canvas.drawCircle(mCenterX, mCenterY, mRadius
          * mInnerCircleRadiusRate, mPaint); 

      drawArrow(canvas); 

      break; 

    case STATUS_NO_FINGER: 

      // 绘制外圆
      mPaint.setStyle(Style.FILL);
      mPaint.setColor(mColorNoFingerOutter);

    } 

  } 

  /**

   */
  private void drawArrow(Canvas canvas)
  {
    if (mArrowDegree != -1)
    {
      mPaint.setStyle(Paint.Style.FILL); 

      canvas.save();
      canvas.rotate(mArrowDegree, mCenterX, mCenterY);
      canvas.drawPath(mArrowPath, mPaint); 

      canvas.restore();
    } 

  } 

  /**
   * 设置当前模式并重绘界面
   *

   */
  public void setMode(Mode mode)
  {
    this.mCurrentStatus = mode;
    invalidate();
  } 

  public void setArrowDegree(int degree)
  {
    this.mArrowDegree = degree;
  } 

  public int getArrowDegree()
  {
    return this.mArrowDegree;
  }
} 

注释很详细，主要就是onDraw时，判断当前状态，绘制不同的显示效果；状态的改变都是GestureLockViewGroup的onTouchEvent中设置的。

  {
    /**
     * 单独选中元素的Id
     *
     * @param position
     */
    public void onBlockSelected(int cId); 

    /**
     * 是否匹配
     *
     * @param matched
     */
    public void onGestureEvent(boolean matched); 

    /**
     * 超过尝试次数
     */
    public void onUnmatchedExceedBoundary();
  }
} 

注释极其详细，用极其不过分~主要就是onTouchEvent中对用户选择的GestureLockView进行判断，以及改变GestureLockView状态等。

5、布局文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  xmlns:zhy="http://schemas.android.com/apk/res/com.zhy.zhy_gesturelockview"
  android:layout_width="match_parent"
  android:layout_height="match_parent" > 

  <com.zhy.zhy_gesturelockview.view.GestureLockViewGroup
    android:id="@+id/id_gestureLockViewGroup"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#F2F2F7"
    android:gravity="center_vertical"
    zhy:count="3"
    zhy:tryTimes="5" />
<!--  zhy:color_no_finger_inner_circle="#ff085D58"
    zhy:color_no_finger_outer_circle="#ff08F0E0"
    zhy:color_finger_on="#FF1734BF" --> 

</RelativeLayout> 

有兴趣的可以自定义属性，把注释的代码添进去就行，当然你也可以什么都不设置，单纯设置宽度和高度，我觉得默认效果也是不错的 ~

6、调用

package com.zhy.zhy_gesturelockview; 

import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast; 

import com.zhy.zhy_gesturelockview.view.GestureLockViewGroup;
import com.zhy.zhy_gesturelockview.view.GestureLockViewGroup.OnGestureLockViewListener; 

public class MainActivity extends Activity
{ 

  private GestureLockViewGroup mGestureLockViewGroup; 

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

    mGestureLockViewGroup = (GestureLockViewGroup) findViewById(R.id.id_gestureLockViewGroup);
    mGestureLockViewGroup.setAnswer(new int[] { 1, 2, 3, 4,5 });
    mGestureLockViewGroup
        .setOnGestureLockViewListener(new OnGestureLockViewListener()
        { 

          @Override
          public void onUnmatchedExceedBoundary()
          {
            Toast.makeText(MainActivity.this, "错误5次...",
                Toast.LENGTH_SHORT).show();
            mGestureLockViewGroup.setUnMatchExceedBoundary(5);
          } 

          @Override
          public void onGestureEvent(boolean matched)
          {
            Toast.makeText(MainActivity.this, matched+"",
                Toast.LENGTH_SHORT).show();
          } 

          @Override
          public void onBlockSelected(int cId)
          {
          }
        });
  } 

}
