超实用的Android手势锁制作实例教程

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

    mArrowPath.close(); 
    mArrowPath.setFillType(Path.FillType.WINDING); 
 
  } 
 
  @Override 
  protected void onDraw(Canvas canvas) 
  { 
 
    switch (mCurrentStatus) 
    { 
    case STATUS_FINGER_ON: 
 
      // 绘制外圆

    this.mArrowDegree = degree; 
  } 
 
  public int getArrowDegree()

  } 
} 

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。

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) 
          { 
          } 
        }); 
  } 
 
}
