创建 service 后台启动
public class FBService extends Service { private static final String TAG = "FBService"; public static final int TYPE_ADD = 0; public static final int TYPE_DEL = 1; private FloatBallManager mFBManager; @Override public void onCreate() { super.onCreate(); Log.d(TAG,"onCreate"); mFBManager = FloatBallManager.getInstance(this); } private void showFloatBall() { Log.d(TAG,"showFloatBall"); mFBManager.addBallView(); //通过mFBManager 在windowmanager添加view } @Override public int onStartCommand(Intent intent, int flags, int startId) { Log.d(TAG,"onStartCommand");showFloatBall(intent); showFloatBall(); return super.onStartCommand(intent, flags, startId); } @Override public IBinder onBind(Intent intent) { return null; } @Override public void onDestroy() { super.onDestroy(); Log.d(TAG,"onDestroy"); }}通过FloatBallManager 在windowmanager 加载 悬浮球布局
public class FloatBallManager { private static final String TAG = "FloatBallManager"; private FloatBallManager(Context ctx){ mCtx = ctx; mWindowManager = (WindowManager) mCtx.getSystemService(Context.WINDOW_SERVICE); //获取WindowManager } public static FloatBallManager getInstance(Context ctx){ if(instance == null){ synchronized(FloatBallManager.class){ if(instance == null){ instance = new FloatBallManager(ctx); } } } return instance; } public void addBallView() { if (mFloatBallView == null) { //获取 整个手机的宽度和高度 DisplayMetrics dm = new DisplayMetrics(); mWindowManager.getDefaultDisplay().getMetrics(dm); mScreenWidth = dm.widthPixels; mScreenHeight = dm.heightPixels; //填充悬浮球 布局 mFBWindow = LayoutInflater.from(mCtx).inflate(R.layout.float_ball, null); mFloatBallView = mFBWindow.findViewById(R.id.float_ball); mFBParams = new LayoutParams(); //设置悬浮球布局的参数 mFBParams.x = mScreenWidth-mFloatBallView.getWidth(); mFBParams.y = mScreenHeight / 2; mFBParams.width = WindowManager.LayoutParams.WRAP_CONTENT; mFBParams.height = WindowManager.LayoutParams.WRAP_CONTENT; mFBParams.gravity = Gravity.LEFT | Gravity.TOP; mFBParams.type = LayoutParams.TYPE_SYSTEM_ALERT | LayoutParams.TYPE_SYSTEM_OVERLAY;//顶层的View ,就要用这两个type mFBParams.format = PixelFormat.TRANSLUCENT;//半透明 mFBParams.flags = LayoutParams.FLAG_NOT_TOUCH_MODAL | LayoutParams.FLAG_NOT_FOCUSABLE;//设置没有焦点不能touch,这样其他的界面才可以滑动和操作 mWindowManager.addView(mFBWindow, mFBParams); //将View 按照mFBParams参数设置,添加到mWindowManager ,mFBParams是告诉mFBWindow 的父view } } //这个方法用来拖动时使用,更新位置 public void updateBallView(int deltaX,int deltaY) { mFBParams.x += deltaX; mFBParams.y += deltaY; if (mWindowManager != null) {// Log.d(TAG,"updateBallView mParams.x = "+mFBParams.x+" mParams.y = "+mFBParams.y); mWindowManager.updateViewLayout(mFBWindow, mFBParams); } }}悬浮球布局
