扫雷4Android(附源码)
最近由于项目需要学习了一下Android ,感觉汗不错。做了一个Android版的扫雷游戏。
游戏简介
在此游戏中，我们使用一个块的网格，其中有一些随机的地雷
下面是效果图
?
一、应用程序布局
使用TableLayout布局控件。设置3行。
<?xml version="1.0" encoding="utf-8"?><TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/back"> <TableRow> <TextView android:id="@+id/timer" android:layout_column="0" android:layout_width="fill_parent" android:layout_height="48px" android:gravity="center_horizontal" android:padding="5dip" android:textColor="#FFFFFF" android:textSize="35sp" android:text=" 0" /> <ImageButton android:id="@+id/smiley" android:layout_column="1" android:scaleType="center" android:padding="5dip" android:layout_width="48px" android:background="@drawable/smiley_button_states" android:layout_height="48px" /> <TextView android:id="@+id/minecount" android:layout_column="2" android:layout_width="fill_parent" android:layout_height="48px" android:gravity="center_horizontal" android:padding="5dip" android:textColor="#FFFFFF" android:textSize="35sp" android:text="000" /> </TableRow> <TableRow> <TextView android:layout_column="0" android:layout_height="50px" android:layout_width="fill_parent" android:layout_span="3" android:padding="10dip" /> </TableRow> <TableRow> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/minefield" android:layout_width="260px" android:layout_height="260px" android:gravity="bottom" android:stretchColumns="*" android:layout_span="3" android:padding="5dip"> </TableLayout> </TableRow></TableLayout>

二、地雷块
Block.java
/** * 地雷的块，继承自Button * @author 记忆的永恒 * */public class Block extends Button { private boolean isCovered; // 块是否覆盖 private boolean isMined; // 下个块 private boolean isFlagged; // 是否将该块标记为一个潜在的地雷 private boolean isQuestionMarked; // 是否是块的问题标记 private boolean isClickable; // 是否可以单击 private int numberOfMinesInSurrounding; // 在附近的地雷数量块 public Block(Context context) { super(context); // TODO Auto-generated constructor stub } public Block(Context context, AttributeSet attrs) { super(context, attrs); // TODO Auto-generated constructor stub } public Block(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } /** * 设置默认参数 */ public void setDefaults() { isCovered = true; isMined = false; isFlagged = false; isQuestionMarked = false; isClickable = true; numberOfMinesInSurrounding = 0; this.setBackgroundResource(R.drawable.square_blue); setBoldFont(); } public void setNumberOfSurroundingMines(int number) { this.setBackgroundResource(R.drawable.square_grey); updateNumber(number); } public void setMineIcon(boolean enabled) { this.setText("M"); if (!enabled) { this.setBackgroundResource(R.drawable.square_grey); this.setTextColor(Color.RED); } else { this.setTextColor(Color.BLACK); } } public void setFlagIcon(boolean enabled) { this.setText("F"); if (!enabled) { this.setBackgroundResource(R.drawable.square_grey); this.setTextColor(Color.RED); } else { this.setTextColor(Color.BLACK); } } public void setQuestionMarkIcon(boolean enabled) { this.setText("?"); if (!enabled) { this.setBackgroundResource(R.drawable.square_grey); this.setTextColor(Color.RED); } else { this.setTextColor(Color.BLACK); } } public void setBlockAsDisabled(boolean enabled) { if (!enabled) { this.setBackgroundResource(R.drawable.square_grey); } else { this.setTextColor(R.drawable.square_blue); } } public void clearAllIcons() { this.setText(""); } private void setBoldFont() { this.setTypeface(null, Typeface.BOLD); } public void OpenBlock() { if (!isCovered) { return; } setBlockAsDisabled(false); isCovered = false; if (hasMine()) { setMineIcon(false); } else { setNumberOfSurroundingMines(numberOfMinesInSurrounding); } } public void updateNumber(int text) { if (text != 0) { this.setText(Integer.toString(text)); switch (text) { case 1: this.setTextColor(Color.BLUE); break; case 2: this.setTextColor(Color.rgb(0, 100, 0)); break; case 3: this.setTextColor(Color.RED); break; case 4: this.setTextColor(Color.rgb(85, 26, 139)); break; case 5: this.setTextColor(Color.rgb(139, 28, 98)); break; case 6: this.setTextColor(Color.rgb(238, 173, 14)); break; case 7: this.setTextColor(Color.rgb(47, 79, 79)); break; case 8: this.setTextColor(Color.rgb(71, 71, 71)); break; case 9: this.setTextColor(Color.rgb(205, 205, 0)); break; } } } public void plantMine() { isMined = true; } public void triggerMine() { setMineIcon(true); this.setTextColor(Color.RED); } public boolean isCovered() { return isCovered; } public boolean hasMine() { return isMined; } public void setNumberOfMinesInSurrounding(int number) { numberOfMinesInSurrounding = number; } public int getNumberOfMinesInSorrounding() { return numberOfMinesInSurrounding; } public boolean isFlagged() { return isFlagged; } public void setFlagged(boolean flagged) { isFlagged = flagged; } public boolean isQuestionMarked() { return isQuestionMarked; } public void setQuestionMarked(boolean questionMarked) { isQuestionMarked = questionMarked; } public boolean isClickable() { return isClickable; } public void setClickable(boolean clickable) { isClickable = clickable; }} 三、主界面1.TableLayout动态添加行 mineField = (TableLayout)findViewById(R.id.MineField);private void showMineField(){ for (int row = 1; row < numberOfRowsInMineField + 1; row++) { TableRow tableRow = new TableRow(this); tableRow.setLayoutParams(new LayoutParams((blockDimension + 2 * blockPadding) * numberOfColumnsInMineField, blockDimension + 2 * blockPadding)); for (int column = 1; column < numberOfColumnsInMineField + 1; column++) { blocks[row][column].setLayoutParams(new LayoutParams( blockDimension + 2 * blockPadding, blockDimension + 2 * blockPadding)); blocks[row][column].setPadding(blockPadding, blockPadding, blockPadding, blockPadding); tableRow.addView(blocks[row][column]); } mineField.addView(tableRow,new TableLayout.LayoutParams( (blockDimension + 2 * blockPadding) * numberOfColumnsInMineField, blockDimension + 2 * blockPadding)); }}?
2.定时器Handler
private Handler timer = new Handler();private int secondsPassed = 0;public void startTimer(){ if (secondsPassed == 0) { timer.removeCallbacks(updateTimeElasped); // tell timer to run call back after 1 second timer.postDelayed(updateTimeElasped, 1000); }}public void stopTimer(){ // disable call backs timer.removeCallbacks(updateTimeElasped);}// timer call back when timer is tickedprivate Runnable updateTimeElasped = new Runnable(){ public void run() { long currentMilliseconds = System.currentTimeMillis(); ++secondsPassed; txtTimer.setText(Integer.toString(secondsPassed)); // add notification timer.postAtTime(this, currentMilliseconds); // notify to call back after 1 seconds // basically to remain in the timer loop timer.postDelayed(updateTimeElasped, 1000); }};3.第一次点击private boolean isTimerStarted; // check if timer already started or notblocks[row][column].setOnClickListener(new OnClickListener(){ @Override public void onClick(View view) { // start timer on first click if (!isTimerStarted) { startTimer(); isTimerStarted = true; } ... }});?
4.第一次点击无雷
private boolean areMinesSet; // check if mines are planted in blocksblocks[row][column].setOnClickListener(new OnClickListener(){ @Override public void onClick(View view) { ... // set mines on first click if (!areMinesSet) { areMinesSet = true; setMines(currentRow, currentColumn); } }});private void setMines(int currentRow, int currentColumn){ // set mines excluding the location where user clicked Random rand = new Random(); int mineRow, mineColumn; for (int row = 0; row < totalNumberOfMines; row++) { mineRow = rand.nextInt(numberOfColumnsInMineField); mineColumn = rand.nextInt(numberOfRowsInMineField); if ((mineRow + 1 != currentColumn) || (mineColumn + 1 != currentRow)) { if (blocks[mineColumn + 1][mineRow + 1].hasMine()) { row--; // mine is already there, don't repeat for same block } // plant mine at this location blocks[mineColumn + 1][mineRow + 1].plantMine(); } // exclude the user clicked location else { row--; } } int nearByMineCount; // count number of mines in surrounding blocks ...}?
5.点击雷块的效果
private void rippleUncover(int rowClicked, int columnClicked){ // don't open flagged or mined rows if (blocks[rowClicked][columnClicked].hasMine() || blocks[rowClicked][columnClicked].isFlagged()) { return; } // open clicked block blocks[rowClicked][columnClicked].OpenBlock(); // if clicked block have nearby mines then don't open further if (blocks[rowClicked][columnClicked].getNumberOfMinesInSorrounding() != 0 ) { return; } // open next 3 rows and 3 columns recursively for (int row = 0; row < 3; row++) { for (int column = 0; column < 3; column++) { // check all the above checked conditions // if met then open subsequent blocks if (blocks[rowClicked + row - 1][columnClicked + column - 1].isCovered() && (rowClicked + row - 1 > 0) && (columnClicked + column - 1 > 0) && (rowClicked + row - 1 < numberOfRowsInMineField + 1) && (columnClicked + column - 1 < numberOfColumnsInMineField + 1)) { rippleUncover(rowClicked + row - 1, columnClicked + column - 1 ); } } } return;}?
6.以问好标记空白
blocks[row][column].setOnLongClickListener(new OnLongClickListener(){ public boolean onLongClick(View view) { // simulate a left-right (middle) click // if it is a long click on an opened mine then // open all surrounding blocks ... // if clicked block is enabled, clickable or flagged if (blocks[currentRow][currentColumn].isClickable() && (blocks[currentRow][currentColumn].isEnabled() || blocks[currentRow][currentColumn].isFlagged())) { // for long clicks set: // 1. empty blocks to flagged // 2. flagged to question mark // 3. question mark to blank // case 1. set blank block to flagged if (!blocks[currentRow][currentColumn].isFlagged() && !blocks[currentRow][currentColumn].isQuestionMarked()) { blocks[currentRow][currentColumn].setBlockAsDisabled(false); blocks[currentRow][currentColumn].setFlagIcon(true); blocks[currentRow][currentColumn].setFlagged(true); minesToFind--; //reduce mine count updateMineCountDisplay(); } // case 2. set flagged to question mark else if (!blocks[currentRow][currentColumn].isQuestionMarked()) { blocks[currentRow][currentColumn].setBlockAsDisabled(true); blocks[currentRow][currentColumn].setQuestionMarkIcon(true); blocks[currentRow][currentColumn].setFlagged(false); blocks[currentRow][currentColumn].setQuestionMarked(true); minesToFind++; // increase mine count updateMineCountDisplay(); } // case 3. change to blank square else { blocks[currentRow][currentColumn].setBlockAsDisabled(true); blocks[currentRow][currentColumn].clearAllIcons(); blocks[currentRow][currentColumn].setQuestionMarked(false); // if it is flagged then increment mine count if (blocks[currentRow][currentColumn].isFlagged()) { minesToFind++; // increase mine count updateMineCountDisplay(); } // remove flagged status blocks[currentRow][currentColumn].setFlagged(false); } updateMineCountDisplay(); // update mine display } return true; }});?
7.记录胜负
// check status of the game at each stepif (blocks[currentRow + previousRow][currentColumn + previousColumn].hasMine()){ // oops game over finishGame(currentRow + previousRow, currentColumn + previousColumn);}// did we win the gameif (checkGameWin()){ // mark game as win winGame();}private boolean checkGameWin(){ for (int row = 1; row < numberOfRowsInMineField + 1; row++) { for (int column = 1; column < numberOfColumnsInMineField + 1; column++) { if (!blocks[row][column].hasMine() && blocks[row][column].isCovered()) { return false; } } } return true;}??
