使用标题＆amp;创建全屏对话框取消/确定按钮

Question

我正在尝试进行类似于此的对话：

但Android Developer Guide和我看到的问题都无法解决我的问题：

1. 标题没有显示，我只是得到了我的服装布局。

2. 我不知道如何在左边放一个“x”，在右边放一个Save-Icon！它应该适用于WINDOW FEATURES ??

对话片段代码：

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    return inflater.inflate(R.layout.dialogfragment_statsentry, container, false);
}

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog mDialog = super.onCreateDialog(savedInstanceState);
    mDialog.setTitle("hello");
    return mDialog;
}

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
}

dialogfragment XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:minWidth="600dp"
    android:layout_height="match_parent"
    android:minHeight="400dp"
    android:orientation="vertical"
    android:padding="10dp">

    <TextView
        android:id="@+id/dialog_statsentry_txvTime"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/dialog_statsentry_edtName"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textPersonName" />
    </android.support.design.widget.TextInputLayout>

</LinearLayout>

我如何调用对话框：

StatsEntryFragmentDialog mFragment = new StatsEntryFragmentDialog();

FragmentManager mManager = getSupportFragmentManager();

if (Utils.isTablet(getApplicationContext())) {
    mFragment.show(mManager, mFragment.TAG); // no fullscreen for bigger displays
}
else {
    FragmentTransaction mTransaction = mManager.beginTransaction();
    mTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);

    mTransaction.add(CONTENT_CONTAINER, mFragment).addToBackStack(mFragment.TAG).commit();
}

提前致谢！

尝试使用Window编写对话框的高度和宽度，如下面的代码

Window window = customDialog.getWindow();
window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
window.setGravity(Gravity.CENTER);
customDialog.show();
