[UI+动画]美女拼图游戏开发

参考鸿洋文章实现的: Android 实战美女拼图游戏 你能坚持到第几关

绘图部分

这里要实现一个自定义View,里面有n*n个图片控件。关于自定义View，

—>自定义View

我们这个View不是继承自View,而是RelativeLayout。

在这之前还要定义两个类。

ImagePiece类:

保存图片以及图片编号

public class ImagePiece {
public int index = 0;
public Bitmap bitmap = null;
}

ImageSplitter类:

对图片进行切割成n*n，返回图片列表.

public class ImageSplitter {
/**
* 将图片切成 , piece *piece
*
* @param bitmap
* @param piece
* @return
*/
public static List<ImagePiece> split(Bitmap bitmap, int piece) {

List<ImagePiece> pieces = new ArrayList<ImagePiece>(piece * piece);
//获取原图片高度宽度
int width = bitmap.getWidth();
int height = bitmap.getHeight();
//宽度取 长宽中短的 除以 列数
int pieceWidth = Math.min(width, height) / piece;

for (int i = 0; i < piece; i++) {
for (int j = 0; j < piece; j++) {
ImagePiece imagePiece = new ImagePiece();
imagePiece.index = j + i * piece;

Log.e("TAG", "imagePiece.index" + (j + i * piece));

int xValue = j * pieceWidth;
int yValue = i * pieceWidth;

imagePiece.bitmap = Bitmap.createBitmap(bitmap, xValue, yValue,
pieceWidth, pieceWidth);
pieces.add(imagePiece);
}
}
return pieces;
}
}

其中关键的就是

Bitmap.createBitmap(bitmap, xValue, yValue,
pieceWidth, pieceWidth);

导入五个参数，从第一个参数的图片里根据后面四个参数截取图片。

自定义View:

1.继承RelativeLayout，初始化变量

2.三个构造函数，进行dip转px(因为设置的是dip而图片使用的是px)和边框大小。

3.重写onMeasure，规划控件大小。先获取原大小,加载图片，切割布置子控件(重新排序)，返回新的大小。

public class GamePintuLayout extends RelativeLayout {
/**
* 设置Item的数量n*n；默认为2
*/
private int mColumn = 3;
/**
* 布局的宽度
*/
private int mWidth;
/**
* 布局的padding
*/
private int mPadding;
/**
* 存放所有的Item
*/
private ImageView[] mGamePintuItems;
/**
* Item的宽度
*/
private int mItemWidth;

/**
* Item横向与纵向的边距
*/
private int mMargin = 3;

/**
* 拼图的图片
*/
private Bitmap mBitmap;
/**
* 存放切完以后的图片bean
*/
private List<ImagePiece> mItemBitmaps;
private boolean once;

public GamePintuLayout(Context context) {
this(context, null);
}

public GamePintuLayout(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}

public GamePintuLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
//dip转px
mMargin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
mMargin, getResources().getDisplayMetrics());
// 设置Layout的内边距，四边一致，设置为四内边距中的最小值
mPadding = min(getPaddingLeft(), getPaddingTop(), getPaddingRight(),
getPaddingBottom());
}

public void setBitmap(Bitmap mBitmap) {
this.mBitmap = mBitmap;
}

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

// 获得游戏布局的边长
mWidth = Math.min(getMeasuredHeight(), getMeasuredWidth());

if (!once) {
initBitmap();
initItem();
}
once = true;
setMeasuredDimension(mWidth, mWidth);
}

/**
* 初始化图片
*/
private void initBitmap() {
if (mBitmap == null)
mBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.aa);

/**
* 将图片切成mColumn*mColumn份
*/
mItemBitmaps = ImageSplitter.split(mBitmap, mColumn);

Collections.sort(mItemBitmaps, new Comparator<ImagePiece>() {
@Override
public int compare(ImagePiece lhs, ImagePiece rhs) {
return Math.random() > 0.5 ? 1 : -1;
}
});
}

/**
* 初始化Item
*/
private void initItem() {
// 获得Item的宽度
int childWidth = (mWidth - mPadding * 2 - mMargin * (mColumn - 1))
/ mColumn;
mItemWidth = childWidth;
mGamePintuItems = new ImageView[mColumn * mColumn];
// 放置Item
for (int i = 0; i < mGamePintuItems.length; i++) {
ImageView item = new ImageView(getContext());

item.setOnClickListener(this);

item.setImageBitmap(mItemBitmaps.get(i).bitmap);
mGamePintuItems[i] = item;

item.setId(i + 1);
item.setTag(i + "_" + mItemBitmaps.get(i).index);

RelativeLayout.LayoutParams lp = new LayoutParams(mItemWidth,
mItemWidth);
// 设置横向边距,不是最后一列
if ((i + 1) % mColumn != 0) {
lp.rightMargin = mMargin;
}
// 如果不是第一列
if (i % mColumn != 0) {
lp.addRule(RelativeLayout.RIGHT_OF,//
mGamePintuItems[i - 1].getId());
}
// 如果不是第一行，//设置纵向边距，非最后一行
if ((i + 1) > mColumn) {
lp.topMargin = mMargin;
lp.addRule(RelativeLayout.BELOW,//
mGamePintuItems[i - mColumn].getId());
}
addView(item, lp);
}

}

/**
* 得到多值中的最小值
*
* @param params
* @return
*/
private int min(int... params) {
int min = params[0];
for (int param : params) {
if (min > param) {
min = param;
}
}
return min;
}
}

布局引用:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.administrator.meinvpinftu.MainActivity">

<com.example.administrator.meinvpinftu.GamePintuLayout
android:id="@+id/id_gameview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerInParent="true"
android:padding="5dp"></com.example.administrator.meinvpinftu.GamePintuLayout>
</RelativeLayout>

public class MainActivity extends AppCompatActivity {
private GamePintuLayout mGameView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mGameView = (GamePintuLayout) findViewById(R.id.id_gameview);
}
}

效果:

添加item点击事件:

接口继承:

implements View.OnClickListener

接口实现:

private ImageView mFirst;
private ImageView mSecond;
@Override
public void onClick(View v) {
// 如果正在执行动画，则屏蔽
if (isAniming)
return;
/**
* 如果两次点击是同一个
*/
if (mFirst == v) {
mFirst.setColorFilter(null);
mFirst = null;
return;
}
// 点击第一个Item
if (mFirst == null) {
mFirst = (ImageView) v;
mFirst.setColorFilter(Color.parseColor("#55FF0000"));
} else
// 点击第二个Item
{
mSecond = (ImageView) v;
exchangeView();
}
}

点击两个ImageView,进行判断。这里的exchange函数里面设置交换时候的动画:

/**
* 动画运行的标志位
*/
private boolean isAniming;
/**
* 动画层
*/
private RelativeLayout mAnimLayout;

/**
* 交换两个Item的图片
*/
private void exchangeView() {
mFirst.setColorFilter(null);
setUpAnimLayout();
// 添加FirstView
ImageView first = new ImageView(getContext());
first.setImageBitmap(mItemBitmaps
.get(getImageIndexByTag((String) mFirst.getTag())).bitmap);
LayoutParams lp = new LayoutParams(mItemWidth, mItemWidth);
lp.leftMargin = mFirst.getLeft() - mPadding;
lp.topMargin = mFirst.getTop() - mPadding;
first.setLayoutParams(lp);
mAnimLayout.addView(first);
// 添加SecondView
ImageView second = new ImageView(getContext());
second.setImageBitmap(mItemBitmaps
.get(getImageIndexByTag((String) mSecond.getTag())).bitmap);
LayoutParams lp2 = new LayoutParams(mItemWidth, mItemWidth);
lp2.leftMargin = mSecond.getLeft() - mPadding;
lp2.topMargin = mSecond.getTop() - mPadding;
second.setLayoutParams(lp2);
mAnimLayout.addView(second);

// 设置动画
TranslateAnimation anim = new TranslateAnimation(0, mSecond.getLeft()
- mFirst.getLeft(), 0, mSecond.getTop() - mFirst.getTop());
anim.setDuration(300);
anim.setFillAfter(true);
first.startAnimation(anim);

TranslateAnimation animSecond = new TranslateAnimation(0,
mFirst.getLeft() - mSecond.getLeft(), 0, mFirst.getTop()
- mSecond.getTop());
animSecond.setDuration(300);
animSecond.setFillAfter(true);
second.startAnimation(animSecond);
// 添加动画监听
anim.setAnimationListener(new Animation.AnimationListener() {

@Override
public void onAnimationStart(Animation animation) {
isAniming = true;
mFirst.setVisibility(INVISIBLE);
mSecond.setVisibility(INVISIBLE);
}

@Override
public void onAnimationRepeat(Animation animation) {

}

@Override
public void onAnimationEnd(Animation animation) {
String firstTag = (String) mFirst.getTag();
String secondTag = (String) mSecond.getTag();

String[] firstParams = firstTag.split("_");
String[] secondParams = secondTag.split("_");

mFirst.setImageBitmap(mItemBitmaps.get(Integer
.parseInt(secondParams[0])).bitmap);
mSecond.setImageBitmap(mItemBitmaps.get(Integer
.parseInt(firstParams[0])).bitmap);

mFirst.setTag(secondTag);
mSecond.setTag(firstTag);

mFirst.setVisibility(VISIBLE);
mSecond.setVisibility(VISIBLE);
mFirst = mSecond = null;
mAnimLayout.removeAllViews();
checkSuccess();
isAniming = false;
}
});

}

游戏成功判断。并进入下一等级:

判断所有的ImageViewTag里的id是否是从0到9依次的:

/**
* 判断游戏是否成功
*/
private void checkSuccess() {
boolean isSuccess = true;
for (int i = 0; i < mGamePintuItems.length; i++) {
ImageView first = mGamePintuItems[i];
Log.e("TAG", getIndexByTag((String) first.getTag()) + "");
if (getIndexByTag((String) first.getTag()) != i) {
isSuccess = false;
}
}

if (isSuccess) {
Toast.makeText(getContext(), "Success , Level Up !",
Toast.LENGTH_LONG).show();
nextLevel();
}
}

public void nextLevel() {
this.removeAllViews();
mAnimLayout = null;
mColumn++;
initBitmap();
initItem();
}

/**
* 获得图片的真正索引
*F
* @param tag
* @return
*/
private int getIndexByTag(String tag) {
String[] split = tag.split("_");
return Integer.parseInt(split[1]);
}

private int getImageIndexByTag(String tag) {
String[] split = tag.split("_");
return Integer.parseInt(split[0]);

}

/**
* 创建动画层
*/
private void setUpAnimLayout() {
if (mAnimLayout == null) {
mAnimLayout = new RelativeLayout(getContext());
addView(mAnimLayout);
}
}

以上就是原作者的所有逻辑，完美运行。
