我正在尝试为DialogFragment设置进入和退出转换,这似乎很直接.以下是我的DrinkDetailActivity中创建对话框的代码:

    fab.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) {
            //create and display the dialog
            DialogFragment orderFragment = new OrderDrinkDialogFragment();

            //set the slide transition for the fragment
            Transition dialSlide = new Slide();
            dialSlide.setDuration(300);

            orderFragment.setEnterTransition(dialSlide);
            orderFragment.setExitTransition(dialSlide);
            orderFragment.show(getFragmentManager(), "order");
        }
    });

这是我的OrderDrinkDialogFragment类的代码:

public class OrderDrinkDialogFragment extends DialogFragment
{
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
        AlertDialog.Builder builder = new AlertDialog.Builder(DrinkDetailActivity.activity);

        //set up the Linear Layout of the dialog
        LinearLayout layout = new LinearLayout(DrinkDetailActivity.activity);
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
                                                                     LinearLayout.LayoutParams.WRAP_CONTENT);
        layout.setOrientation(LinearLayout.VERTICAL);
        layout.setLayoutParams(params);

        //set up the …

我的应用程序有问题.我像这样使用全屏选项:

public void setFullscreen() {
    requestWindowFeature(Window.FEATURE_NO_TITLE);

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

但是,稍后在游戏过程中,当我显示AlertDialog的帮助/信息时,状态栏会在几分之一秒内恢复并再次消失,从而产生闪烁或跳跃效果.此外,Dialog本身并不是应该居中,几乎就像它认为有一个状态栏一样.

以下是我显示对话框的方法:

protected Dialog onCreateDialog(int id) {
TextView tv;

switch (id) {
case MENU_HELP:
       tv = new TextView(this);
                   tv.setText(R.strings.help_msg);

       return new AlertDialog.Builder(BlackJackView.this)
       .setIcon(android.R.drawable.ic_menu_help)
       .setTitle("How-To")
       .setView(tv)
       .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int whichButton) {
                          /* User clicked OK so do some stuff */
                   }
       })
       .create();
  }

  ………

  }
  return null;
}

有谁知道可能导致这种情况出现/消失的原因是什么？如何让它停止这种跳跃行为？

感谢你的帮助.
