java - 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类似的对话框:

但是 Android 开发者指南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. 我不知道如何在左侧放置一个“x”，在右侧放置一个保存图标!它应该与窗口功能一起使用吗？

对话框 fragment 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);
}

对话框 fragment 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!

使用像下面的代码这样的窗口以编程方式尝试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();
