本文实例为大家分享了Android实现触摸移动的悬浮窗的具体代码，供大家参考，具体内容如下
1.触摸移动的悬浮窗的快速实现 UI
2. 悬浮窗实现
2.1 悬浮窗权限
为了偷懒，我SDK选择比较低的17，如果不配置权限，则应用会运行报错
正规流程，查询是否有悬浮窗权限，如果没有需要提示，并跳转到悬浮窗设置界面“即是否允许运行在其他应用上面”
<uses-sdk android:minSdkVersion="17" android:targetSdkVersion="17" /><uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
2.2 悬浮窗配置初始化
这里主要关注 mParams.type 和 mParams.flags 这两个参数是核心，我们也可以使用View来加载一个布局，为了侧重悬浮窗界面，我直接使用TextView演示
private void initFloatWindow() { if (mShow == null) { mWm = (WindowManager) getSystemService(Context.WINDOW_SERVICE); mShow = new TextView(this); mShow.setText("I Love You"); mShow.setTextColor(Color.RED); mShow.setTextSize(50); mShow.setOnTouchListener(new View.OnTouchListener() { int lastX = 0; int lastY = 0; int paramX = 0; int paramY = 0; @Override public boolean onTouch(View view, MotionEvent motionEvent) { switch (motionEvent.getAction()) { case MotionEvent.ACTION_DOWN: lastX = (int) motionEvent.getRawX(); lastY = (int) motionEvent.getRawY(); paramX = mParams.x; paramY = mParams.y; break; case MotionEvent.ACTION_MOVE: int dx = (int) motionEvent.getRawX() - lastX; int dy = (int) motionEvent.getRawY() - lastY; mParams.x = paramX + dx; mParams.y = paramY + dy; mWm.updateViewLayout(mShow, mParams); break; } return true; } }); mParams = new WindowManager.LayoutParams(); mParams.width = WindowManager.LayoutParams.WRAP_CONTENT; mParams.height = WindowManager.LayoutParams.WRAP_CONTENT; mParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT; // 实现悬浮窗可以移动的属性 mParams.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE; mParams.format = PixelFormat.TRANSPARENT; } } 2.3 悬浮窗显示
mWm.addView(mShow, mParams);
2.4 悬浮窗隐藏
