android全局Dialog

全局的Dialog，可在service中显示

public static void ShowDialog(final Context context ,boolean cancle,DialogInterface.OnClickListener onClickListener,String messager,String title){AlertDialog.Builder builder = new AlertDialog.Builder(context,AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);builder.setTitle(title);builder.setCancelable(cancle);builder.setPositiveButton("确定",  onClickListener);builder.setMessage(messager);AlertDialog dialog = builder.create();dialog .getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);dialog.show()

必须添加权限

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
