//障碍物 Y 坐标

int baffleY [] = null;

//障碍物标签

int baffleArr[][] = null;

/*画障碍物/

public void drawBaffle(Canvas canvas){

//屏幕宽高

screenWidth = screenWidth != 0 ? screenWidth : MainActivity.tableWidth;

screenHeight = screenHeight != 0 ? screenHeight: MainActivity.tableHeight;

//宽

perWidth = perWidth != 0 ? perWidth : screenWidth/(baffleNum+2);

//间隔宽

InterWidth = InterWidth != 0 ? InterWidth : perWidth*2/(baffleNum+1);

int tempLev = baffleLev/2;

//每份高

perHeight = perHeight != 0 ? perHeight : screenHeight/2/(colors.length+tempLev+2);

//间隔高

InterHeight = InterHeight !=0 ? InterHeight : perHeight/2;

int tempHeight = 0;

int tempH = 0;

int tempWidht = 0;

int tempW = 0;

//屏幕宽

public static int tableWidth;

//屏幕高

public static int tableHeight;

//常亮属性

PowerManager powerManager = null;

WakeLock wakeLock = null;

MediaPlayer media = null;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

//设置常亮

this.powerManager = (PowerManager)this.getSystemService(Context.POWER_SERVICE);

this.wakeLock = this.powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Lock");

//获取窗口管理器

WindowManager windowManager = getWindowManager();

Display display = windowManager.getDefaultDisplay();

DisplayMetrics metrics = new DisplayMetrics();

display.getMetrics(metrics);

//获取屏幕宽和高

tableWidth = metrics.widthPixels;

tableHeight = metrics.heightPixels;

2.设置按钮属性

//按钮宽和高

int botwidth = (int) ((int) tableWidth/2.5);

int botheight = (int) ((int) tableHeight/8);

//设置 play

ImageButton playbot =(ImageButton) findViewById(R.id.play);

ViewGroup.LayoutParams playbotn = (ViewGroup.LayoutParams) playbot.getLayoutParams();

playbotn.width = botwidth;

playbotn.height = botheight;

playbot.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View source) {

Intent intent = new Intent(MainActivity.this, PlayActivity.class);

startActivity(intent);

}

});

//设置 exit

ImageButton exitbot =(ImageButton) findViewById(R.id.exit);

ViewGroup.LayoutParams exitbotn = (ViewGroup.LayoutParams) exitbot.getLayoutParams();

exitbotn.width = botwidth;

exitbotn.height = botheight;

3.设置游戏

final Timer timer = new Timer();

timer.schedule(new TimerTask() {

@Override

public void run() {

//结束判断

if( (playView.circleY + playView.radius) > (playView.paiY + playView.paiHeight) ){

timer.cancel();

playView.isOver = true;

}else{

//碰到墙壁时 X 的改变

if( playView.circleX <= playView.radius

|| playView.circleX >= playView.screenWidth - playView.radius ){

playView.speedX = -playView.speedX;

}

//碰到墙壁时 Y 的改变

if( playView.circleY <= playView.radius

|| ( playView.circleX >= playView.paiX

&& playView.circleX <= (playView.paiX + playView.paiWidth)

&& (playView.circleY + playView.radius) >= playView.paiY

&& (playView.circleY + playView.radius) <= playView.paiY + playView.paiHeight) ){

playView.speedY = -playView.speedY;

}

//初始化后才判断

if( playView.baffleX != null ){

//碰到障碍时 X 的改变

for( int i = 0; i < playView.baffleLev; i++ ){

int tag = 0;

if( playView.circleY >= playView.baffleY[i]

&& playView.circleY <= (playView.baffleY[i] + playView.perHeight) ){

for( int j = 0; j < playView.baffleNum; j++ ){

if( playView.baffleArr[j][i] == 0 ){

if( playView.circleX >= (playView.baffleX[j] - playView.radius)

&& playView.circleX <= (playView.baf
