要在Android应用中设置悬浮菜单窗口,可以通过使用系统提供的悬浮窗口权限来实现。以下是设置悬浮菜单窗口的一般步骤:
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !Settings.canDrawOverlays(this)) {
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, REQUEST_CODE_OVERLAY_PERMISSION);
}
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
View floatingView = LayoutInflater.from(this).inflate(R.layout.floating_menu, null);
windowManager.addView(floatingView, params);
请注意,在使用悬浮窗口时需要注意用户体验和隐私安全问题,避免滥用悬浮窗口功能。
