Android基于GridView实现的翻牌游戏效果

  好久没有写博客了,上一篇博文距现在都有三个多月了,实在是惭愧。但是这段时间仍然是在忙于项目或是自我充电。这几天实现了一个基于GridView的翻牌动画效果,这里就将其整理出来同各位分享。

  一、整体介绍 

  GridView设置15个Item(5*3),刚好满屏显示(没有ScrollBar),没有点击某个Item前可以使用摇一摇功能对GridView中的图片进行切换,点击某个Item时对应的图片放大,然后实现“翻牌”效果,并将该Item中显示的图片切换为对应的文字。随后所有其他的Item也自动实现翻牌效果。

  (2)效果图

    

  二、详细介绍

  按上面的目录结构从上致下

  1、GridAdapter 继承至 BaseAdapter

    重点代码:

    (1)自定义的一个Item touch事件监听接口

1  public interface  OnItemTouchedListener {
2         public boolean onItemTouch (View v, MotionEvent event, int position);
3  }

    (2)设置OnItemTouchedListener

1  public void setOnItemTouchedListener(OnItemTouchedListener onItemTouchedListener) {
2         this.listener = onItemTouchedListener;
3  }

    (3)getView()函数中动态设置 Item的高、宽加载网络图片为每个Item设置OnTouchListener

 1 @Override
 2     public View getView(final int position, View convertView, ViewGroup parent) {
 3         LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
 4         convertView = inflater.inflate(R.layout.grid_item, parent, false);
 5 
 6         LayoutParams layoutParams = convertView.getLayoutParams();
 7         layoutParams.width = viewWidth;
 8         layoutParams.height = viewHeight;
 9         convertView.setLayoutParams(layoutParams);
10         ImageView imageView = (ImageView) convertView.findViewById(R.id.grid_image);
11 
12         DisplayImageOptions options = new DisplayImageOptions.Builder()//
13                 .cacheInMemory(true)//
14                 .cacheOnDisc(true)//
15                 .bitmapConfig(Config.RGB_565)//
16                 .build();
17         ImageLoader.getInstance().displayImage(urlArray.get(position),
18                 imageView, options);
19         convertView.setOnTouchListener(new OnTouchListener() {
20 
21             @Override
22             public boolean onTouch(View v, MotionEvent event) {
23 
24                 return listener.onItemTouch(v, event, position);
25             }
26         });
27 
28         return convertView;
29     }

   2、RotateAnimation

  参考于github上jianghejie的3DNumberRotate项目中的NumberRotate3DAnimation类,基于Camera实现数字3D翻转动画。

  3、自定义的Application类

  项目中使用了universal-image-loader加载网络图片,在这里对ImageLoader进行初始化:

 1 private void initImageLoader() {
 2 
 3         DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder() //
 4                 .showImageForEmptyUri(R.mipmap.empty_img) //
 5                 .showImageOnFail(R.mipmap.empty_img) //
 6                 .cacheInMemory(true) //
 7                 .cacheOnDisc(true) //
 8                 .build();//
 9 
10         File cacheDir = StorageUtils.getCacheDirectory(getApplicationContext());
11         ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(
12                 getApplicationContext())//
13                 .memoryCache(new LruMemoryCache(5 * 1024 * 1024))//
14                 .memoryCacheSize(10 * 1024 * 1024)//
15                 .defaultDisplayImageOptions(defaultOptions)//
16                 .discCache(new UnlimitedDiscCache(cacheDir))//
17                 .discCacheFileNameGenerator(new HashCodeFileNameGenerator())//
18                 .build();
19         ImageLoader.getInstance().init(config);
20     }

  4、util包中的几个工具类

    (1)Constants:放一些常量,这里我存放的是GridView中网络图片的路径;

    (2)DisplayUtil:这是关于显示的一个工具类,包括获取屏幕高宽、dp转px等功能;

    (3)ItemCenterMeasure:这个类是设计用来根据GridView高宽计算Item尺寸的,其实可以省去,或者直接归并到DisplayUtil中;

  5、MainActivity中功能较多写的比较杂乱

    主要代码:

    (1)Adapter设置自定义的OnItemTouchedListener

 1  mAdapter.setOnItemTouchedListener(new GridAdapter.OnItemTouchedListener() {
 2 
 3             @Override
 4             public boolean onItemTouch(View v, MotionEvent event, int position) {
 5                 mView = v;
 6                 currentPos = position;
 7                 if(event.getAction() == MotionEvent.ACTION_DOWN){
 8                     if (isClicked) {
 9                         Toast toast = Toast.makeText(context, getString(R.string.warning),
10                                 Toast.LENGTH_SHORT);
11                         toast.setGravity(Gravity.CENTER, 0, 0);
12                         toast.show();
13                         return false;
14                     } else{
15                         //play sound
16                         soundPool.play(music, 1, 1, 0, 0, 1);
17                         //trigger zoom animation on items
18                         ScaleAnimation scaleAnimation = new ScaleAnimation(1.0f, 1.1f, 1.0f, 1.1f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
19                         scaleAnimation.setDuration(500);
20                         AnimationSet animationSet = new AnimationSet(true);
21                         animationSet.addAnimation(scaleAnimation);
22                         animationSet.setFillAfter(true);
23                         animationSet.setAnimationListener(new Animation.AnimationListener() {
24 
25                             @Override
26                             public void onAnimationStart(Animation animation) {
27 
28                             }
29 
30                             @Override
31                             public void onAnimationRepeat(Animation animation) {
32 
33                             }
34 
35                             @Override
36                             public void onAnimationEnd(Animation animation) {
37                                 enableRefreshFirst = true;
38                                 RotateAnimation rotateAnim = null;
39 
40                                 float cX = mView.getWidth() / 2.0f;
41                                 float cY = mView.getHeight() / 2.0f;
42                                 rotateAnim = new RotateAnimation(cX, cY);
43 
44                                 if (rotateAnim != null) {
45                                     rotateAnim.setInterpolatedTimeListener(MainActivity.this, mView);
46                                     rotateAnim.setFillAfter(true);
47                                     rotateAnim.setAnimationListener(new Animation.AnimationListener() {
48 
49                                         @Override
50                                         public void onAnimationStart(Animation animation) {
51 
52                                         }
53 
54                                         @Override
55                                         public void onAnimationRepeat(Animation animation) {
56 
57                                         }
58 
59                                         @Override
60                                         public void onAnimationEnd(Animation animation) {
61                                             handler.postDelayed(new Runnable() {
62 
63                                                 @Override
64                                                 public void run() {
65                                                     otherItemRotate();
66                                                 }
67                                             }, 500);
68                                         }
69                                     });
70                                     mView.startAnimation(rotateAnim);
71 
72                                 }
73 
74                                 isClicked = true;
75                             }
76                         });
77                         v.startAnimation(animationSet);
78                     }
79                 }
80 
81                 return false;
82             }
83         });

    (2)动态创建一个TextView,并算出GridView的高、宽

      其中计算GridView的高度这一句(DisplayUtil.SCREEN_HEIGHT_PIXELS - DisplayUtil.dp2px(16) * 2 - tvBmHeight - 80)在我设备(分辨率:1920*1080)上要减去80px才能使所有的Item整好全部显示出来,不知道为什么,如果不减去80px,GridViw 中的最后一行Item将会显示不完全也就是说要通过滑动ScrollBar才能看全。这一点还望大神能给予指点。

 1 private void createCRTextView() {
 2         LinearLayout ll = (LinearLayout) findViewById(R.id.logo_ly);
 3         tvBm = new TextView(context);
 4         tvBm.setText(getResources().getString(R.string.logo));
 5         tvBm.setTextAppearance(context, R.style.logoTextView);
 6         LinearLayout.LayoutParams crParams = new LinearLayout.LayoutParams(GridLayout.LayoutParams.WRAP_CONTENT, GridLayout.LayoutParams.WRAP_CONTENT);
 7         crParams.topMargin = 5;
 8         crParams.bottomMargin = 10;
 9         crParams.gravity = Gravity.CENTER;
10         tvBm.setLayoutParams(crParams);
11 
12         tvBm.setOnClickListener(new View.OnClickListener() {
13 
14             @Override
15             public void onClick(View v) {
16                 ScaleAnimation  scaleAnim = new ScaleAnimation(1.0f, 1.2f, 1.0f, 1.2f,
17                         Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
18                 scaleAnim.setDuration(500);
19                 scaleAnim.setFillAfter(false);
20                 tvBm.startAnimation(scaleAnim);
21             }
22         });
23 
24         ll.addView(tvBm);
25         int tvBmHeight = crParams.height + 5 + 10;
26 
27 
28         gridWidthPix = DisplayUtil.SCREEN_WIDTH_PIXELS - DisplayUtil.dp2px(16) * 2;
29         //I am not sure why the right of next equality should minus 80px to display all items in the gridview without scrollbar in my devices (1       920*1080),
30         //this may make a bad adaption for various devices with different resolution ratio
31         gridHeightPix = DisplayUtil.SCREEN_HEIGHT_PIXELS - DisplayUtil.dp2px(16) * 2 - tvBmHeight - 80;
32 
33 
34     }

    (3)摇一摇触发的时候更新GridView中的图片路径

 @Override
    public void onSensorChanged(SensorEvent event) {
        int sensorType = event.sensor.getType();
        float[] values = event.values;
        if (sensorType == Sensor.TYPE_ACCELEROMETER) {
            //values[0] X axis acceleration;values[1] Y axis acceleration;values[2] Z axis acceleration
            if (Math.abs(values[0]) > 17 || Math.abs(values[1]) > 17 || Math.abs(values[2]) > 17) {

                if (!isClicked) {
                    vibrator.vibrate(500);
                    mAdapter.setUrls(Constants.getUrls(2));
                    mGridView.invalidate();
                }
            }
        }


    }

  6、还有一个自定义的GridView,实现禁止滑动

  重写dispatchTouchEvent方法

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_MOVE) {
            return true;//禁止gridview滑动
        }
        return super.dispatchTouchEvent(ev);
    }

  7、布局文件这里就不给予说明了,很简单明了的,需要参考的可以直接下源码看。

    源码下载链接:

    (1)CSDN:需要1个下载积分,积分有点缺您要是愿意打赏请点这里下载

    (2)GitHub:实在吝啬或是没有积分也没关系,请到这里下载,当然也希望你Star一下,或是Fork;

  好了到此算是写完了,如果对您有用,劳烦您点个赞或是分享一下;如果您对代码有一些建议,期待您在评论处给予指正。

  最近状态有点不佳,送给自己以及各位一句话共勉:

业精于勤 荒于嬉;行成于思 毁于随
