创建带有标题和“取消/确定”按钮的全屏对话框

Question

我正在尝试创建一个与此对话框类似的对话框：

但是，无论是《 Android开发人员指南》还是我所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. 我不知道如何在左侧放置“ x”，在右侧放置保存图标！ 它应该与WINDOW功能一起使用吗？

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);
}

对话片段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>

以及如何调用对话框：

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！

像下面的代码一样使用Window尝试以编程方式设置对话框的高度和宽度

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