先看一下效果然后贴代码
最上面是自定义的ActionBar，布局里面有两个TextView。一个用于显示level，一个用于显示倒计时
下面就是自定义的RelativeLayout。用于显示九个一打乱的bitmap
接下来就是代码：
首先是将图片分割的工具类
ImageUtil.java
package com.example.util;import java.util.ArrayList;import java.util.List;import android.graphics.Bitmap;public class ImageUtil { /* * 将图片分成piece*piece份小图片，每份就是ImagePiece，存在imgList里面 */ public static List<ImagePiece> splitImage(Bitmap bitmap, int piece) { List<ImagePiece> imgList = new ArrayList<ImagePiece>(); //每张图片的宽高 int pieceWidth = bitmap.getWidth() / piece; int pieceHeight = bitmap.getHeight() / piece; for (int i = 0; i < piece; i++) { for (int j = 0; j < piece; j++) { ImagePiece imagePiece = new ImagePiece(); imagePiece.setIndex(j + i * piece); int x = j * pieceWidth; int y = i * pieceHeight; imagePiece.setBitmap(Bitmap.createBitmap(bitmap, x, y, pieceWidth, pieceHeight)); imgList.add(imagePiece); } } return imgList; }}分割后的每一个ImagePiece的实体类
ImagePiece.java
package com.example.util;import android.graphics.Bitmap;public class ImagePiece { private int index;//每小张图片的编号 private Bitmap bitmap; public ImagePiece() {} public ImagePiece(int index, Bitmap bitmap) { this.index = index; this.bitmap = bitmap; } public int getIndex() { return index; } public void setIndex(int index) { this.index = index; } public Bitmap getBitmap() { return bitmap; } public void setBitmap(Bitmap bitmap) { this.bitmap = bitmap; } @Override public String toString() { return "ImagePiece [index=" + index + ", bitmap=" + bitmap + "]"; }}接下来是自定义的GameLayout.java
package com.example.view;import java.util.Collections;import java.util.Comparator;import java.util.List;import android.content.Context;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.graphics.Color;import android.os.Handler;import android.os.Message;import android.util.AttributeSet;import android.util.TypedValue;import android.view.View;import android.view.View.OnClickListener;import android.view.animation.Animation;import android.view.animation.Animation.AnimationListener;import android.view.animation.TranslateAnimation;import android.widget.ImageView;import android.widget.RelativeLayout;import android.widget.Toast;import com.example.pintu.R;import com.example.util.ImagePiece;import com.example.util.ImageUtil;public class GameLayout extends RelativeLayout implements OnClickListener { private int GameLayoutWidth; private int GameLayoutHeight; private int column; private int padding;// 类似于xml中的android:padding private int margin;// 类似于xml中的android:layout_margin private ImageView[] gameItem; private int itemWidth; private int itemHeight; private Bitmap bitmap; private List<ImagePiece> imgList; private boolean once; public GameLayout(Context context) { super(context); init(); } public GameLayout(Context context, AttributeSet attrs) { super(context, attrs); init(); } public GameLayout(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); init(); } // 初始化参数 private void init() { column = 3; margin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 2, getResources().getDisplayMetrics()); padding = min(getPaddingLeft(), getPaddingRight(), getPaddingTop(), getPaddingBottom()); once = false; } private int min(int... params) { int min = params[0]; for (int param : params) { min = Math.min(min, param); } return min; } @Override // onMeasure和onLayout会多次调用，所有要有once标识符 protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); if (!once) { GameLayoutHeight = getMeasuredHeight(); GameLayoutWidth = getMeasuredWidth(); // 进行切图，并打乱次序 initBitmap(); // 九宫格的绘制 initItem(); // 判断是否开启时间 checkTimeEnable(); once = true; } setMeasuredDimension(GameLayoutWidth, GameLayoutHeight); } // 进行切图，并排序 private void initBitmap() { // 获取bitmap，然后转化为和屏幕一样大小 if (bitmap == null) { bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.girl); bitmap = Bitmap.createScaledBitmap(bitmap, GameLayoutWidth, GameLayoutHeight, true); } // 切图 imgList = ImageUtil.splitImage(bitmap, column); // 使用sort打乱次序 Collections.sort(imgList, new Comparator<ImagePiece>() { @Override public int compare(ImagePiece lhs, ImagePiece rhs) { return Math.random() > 0.5 ? 1 : -1; } }); } // 九宫格的绘制 private void initItem() { // 设置gameItem的宽高 itemWidth = (GameLayoutWidth - padding * 2 - margin * (column - 1)) / column; itemHeight = (GameLayoutHeight - padding * 2 - margin * (column - 1)) / column; gameItem = new ImageView[column * column]; // 设置九宫格中每个格子对应的Bitmap，id和tag以及LayoutParams // 最后添加到GameLayout中 for (int i = 0; i < gameItem.length; i++) { ImageView item = new ImageView(getContext()); item.setImageBitmap(imgList.get(i).getBitmap()); item.setId(i + 1);// ********************************** // index是本质编号，id是打乱后的编号 item.setTag(i + "_" + imgList.get(i).getIndex()); item.setOnClickListener(this);// 实现图片的交换 gameItem[i] = item; RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams( itemWidth, itemHeight); // 设置横向间距，通过leftMargin。如果不是第一列 if ((i % column) != 0) { lp.leftMargin = margin; lp.addRule(RelativeLayout.RIGHT_OF, gameItem[i - 1].getId()); } // 设置横向间距。如果不是第一行，设置topMargin和rule if ((i + 1) > column) { lp.topMargin = margin; lp.addRule(RelativeLayout.BELOW, gameItem[i - column].getId()); // anchor------The id of another view to use as an anchor, // or a boolean value(represented as RelativeLayout.TRUE) for // true // or 0 for false). For verbs that don't refer to another // sibling // (for example, ALIGN_WITH_PARENT_BOTTOM) just use -1. // 注意，后面的参数不能为0（0 for false），所以打星号的地方要+1 } addView(item, lp); } } private int time; private boolean isTimeEnabled = false;// 默认不开启时间 private void checkTimeEnable() { if (isTimeEnabled) { // 根据当前等级设置时间 time = (int) Math.pow(3.0, column); myHandler.sendEmptyMessage(TIME_CHANGED); } } private ImageView mFirst; private ImageView mSecond; private boolean isAnimation = false; // 实现图片的交换 @Override public void onClick(View v) { // 防止用户疯狂的点 if (isAnimation) { return; } // 两次点击同一个item if (mFirst == v) { mFirst.setColorFilter(null); mFirst = null; return; } if (mFirst == null) {// 第一次点击的是新的图片 mFirst = (ImageView) v; mFirst.setColorFilter(Color.parseColor("#55FF0000")); } else {// 第二次点击也是新的图片 mSecond = (ImageView) v; exchageView();// 交换图片 } } private RelativeLayout mAnimLayout;// 实现动画切换的变量 // 交换图片 private void exchageView() { mFirst.setColorFilter(null); final String firstTag = (String) mFirst.getTag(); final String secondTag = (String) mSecond.getTag(); final Bitmap firstBitmap = imgList.get(getImageIdByTag(firstTag)) .getBitmap(); final Bitmap secondBitmap = imgList.get(getImageIdByTag(secondTag)) .getBitmap(); // 构造动画层 if (mAnimLayout == null) { mAnimLayout = new RelativeLayout(getContext()); addView(mAnimLayout); } // 构造图片交换动画 final ImageView first = new ImageView(getContext()); first.setImageBitmap(firstBitmap); LayoutParams lp = new LayoutParams(itemWidth, itemHeight); lp.leftMargin = mFirst.getLeft() - padding; lp.topMargin = mFirst.getTop() - padding; first.setLayoutParams(lp); mAnimLayout.addView(first); final ImageView second = new ImageView(getContext()); second.setImageBitmap(secondBitmap); LayoutParams lp2 = new LayoutParams(itemWidth, itemHeight); lp2.leftMargin = mSecond.getLeft() - padding; lp2.topMargin = mSecond.getTop() - padding; second.setLayoutParams(lp2); mAnimLayout.addView(second); TranslateAnimation animation = new TranslateAnimation(0, mSecond.getLeft() - mFirst.getLeft(), 0, mSecond.getTop() - mFirst.getTop()); animation.setDuration(300); animation.setFillAfter(true); first.startAnimation(animation); TranslateAnimation animation2 = new TranslateAnimation(0, mFirst.getLeft() - mSecond.getLeft(), 0, mFirst.getTop() - mSecond.getTop()); animation2.setDuration(300); animation2.setFillAfter(true); second.startAnimation(animation2); animation.setAnimationListener(new AnimationListener() { @Override public void onAnimationStart(Animation animation) { isAnimation = true; mFirst.setVisibility(View.INVISIBLE); mSecond.setVisibility(View.INVISIBLE); } @Override public void onAnimationRepeat(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { // 交换图片（注意tag也要交换） isAnimation = false; mFirst.setImageBitmap(secondBitmap); mSecond.setImageBitmap(firstBitmap); mFirst.setTag(secondTag); mSecond.setTag(firstTag); mFirst.setVisibility(View.VISIBLE); mSecond.setVisibility(View.VISIBLE); mFirst = mSecond = null; mAnimLayout.removeAllViews(); checkSuccess();// 判断是否过关 } }); } private int getImageIdByTag(String tag) { String[] split = tag.split("_"); return Integer.parseInt(split[0]); } // item.setTag(i + "_" + imgList.get(i).getIndex()); private int getImageIndexByTag(String tag) { String[] split = tag.split("_"); return Integer.parseInt(split[1]); } // 判断是否过关。过关条件就是0到8有序排列 private void checkSuccess() { boolean isSuccess = true; for (int i = 0; i < gameItem.length; i++) { ImageView imageView = gameItem[i]; if (getImageIndexByTag((String) imageView.getTag()) != i) { isSuccess = false; } } if (isSuccess) { isGameSuccess = true; myHandler.removeMessages(TIME_CHANGED); Toast.makeText(getContext(), "Success ! Level Up !", Toast.LENGTH_SHORT).show(); myHandler.sendEmptyMessage(NEXT_LEVEL);// 进入下一关 } } private static final int NEXT_LEVEL = 0x001; private static final int TIME_CHANGED = 0x002; private boolean isGameSuccess; private boolean isGameOver; private Handler myHandler = new Handler() { public void handleMessage(Message msg) { switch (msg.what) { case NEXT_LEVEL:// 进入下一关 column++; if (mListener != null) { mListener.nextLevel(column); } break; case TIME_CHANGED: if (isGameSuccess || isGameOver || isPause) return; if (mListener != null) { mListener.timeChanged(time); if (time == 0) { isGameOver = true; mListener.gameOver(); return; } } time--; myHandler.sendEmptyMessageDelayed(TIME_CHANGED, 1000); break; } }; }; public void nextLevel() { this.removeAllViews(); mAnimLayout = null; isGameSuccess = false; checkTimeEnable(); initBitmap(); initItem(); }; public void restart() { isGameOver = false; nextLevel(); } private boolean isPause; public void pause(){ isPause = true; myHandler.removeMessages(TIME_CHANGED); } public void resume(){ if(isPause){ isPause = false; myHandler.sendEmptyMessage(TIME_CHANGED); } } // 定义接口，用于通知主界面的level和time public interface GameListener { void nextLevel(int level); void timeChanged(int currentTime); void gameOver(); } public GameListener mListener; public void setOnGameListener(GameListener Listener) { this.mListener = Listener; } public void setTimeEnabled(boolean isTimeEnabled) { this.isTimeEnabled = isTimeEnabled; }}GameLayout实现如下几个功能
1.自定义容器
2.实现图片交换onCLickListener
3.实现过关逻辑interface GameListener
4.实现游戏的结束和暂停，这需要配合activity的onPause和onResume
接下来就是MainActivity.java
package com.example.pintu;import android.app.Activity;import android.app.AlertDialog;import android.content.DialogInterface;import android.content.DialogInterface.OnClickListener;import android.os.Bundle;import android.view.Window;import android.widget.TextView;import com.example.view.GameLayout;import com.example.view.GameLayout.GameListener;public class MainActivity extends Activity { private GameLayout gameLayout; private TextView levelView, timeView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 自定义ActionBar， // 用法参考http://blog.csdn.net/jia20003/article/details/12966489 requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); setContentView(R.layout.main); getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title); levelView = (TextView) findViewById(R.id.id_level); levelView.setText("level 1"); timeView = (TextView) findViewById(R.id.id_time); gameLayout = (GameLayout) findViewById(R.id.pintu); gameLayout.setTimeEnabled(true); gameLayout.setOnGameListener(new GameListener() { @Override public void timeChanged(int currentTime) { timeView.setText("" + currentTime); } @Override public void nextLevel(int level) { new AlertDialog.Builder(MainActivity.this).setTitle("LEVEL UP") .setPositiveButton("next level", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { gameLayout.nextLevel(); } }).show(); // 3*3对应level 1；4*4对应level 2 levelView.setText("level " + (level - 2)); } @Override public void gameOver() { new AlertDialog.Builder(MainActivity.this) .setTitle("Game Over") .setPositiveButton("RESTART", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { gameLayout.restart(); } }).setNegativeButton("QUIT", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { finish(); } }).show(); } }); } @Override protected void onPause() { super.onPause(); gameLayout.pause(); } @Override protected void onResume() { super.onResume(); gameLayout.resume(); }}适合自定义ActionBar还要在styles.xml添加
<style name="MyTheme" parent="android:Theme.Light"> </style> 以及修改AndroidManifest.xml
android:theme="@style/MyTheme"<!-- 就算MyTheme和自动生成的AppBaseTheme一样，还是要重新定义 --><!-- 因为ActionBar布局改变了 -->最后给出两个布局
main.xml
<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" tools:context="com.example.pintu.MainActivity" > <com.example.view.GameLayout android:id="@+id/pintu" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="2dp" > </com.example.view.GameLayout></RelativeLayout>以及自定义的actionbar的布局title.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout 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:orientation="horizontal" tools:context=".MainActivity" android:background="#FFFFFF" > <TextView android:id="@+id/id_level" android:layout_width="0sp" android:layout_weight="1" android:gravity="left" android:textSize="20sp" android:layout_height="wrap_content" /> <TextView android:id="@+id/id_time" android:layout_width="0sp" android:layout_weight="1" android:gravity="right" android:textSize="20sp" android:layout_height="wrap_content" /></LinearLayout> 0 0
