Android 全屏DialogFragment

Full screen DialogFragment

提问by invertigo

I am trying to create a DialogFragment with a width of MATCH_PARENT so the dialog is nearly full screen (leaving the padding around the edges for the floating look). I have seen this solution Full Screen DialogFragment in Androidbut am trying to avoid the hack of setting the width to 1000dp. With my current layout, whether I use FILL_PARENT or MATCH_PARENT it seems to be setting the width and height to WRAP_CONTENT.

我正在尝试创建一个宽度为 MATCH_PARENT 的 DialogFragment，因此对话框几乎是全屏的（在边缘留下填充以实现浮动外观）。我在 Android 中看到了这个解决方案Full Screen DialogFragment，但我试图避免将宽度设置为 1000dp 的问题。对于我当前的布局，无论我使用 FILL_PARENT 还是 MATCH_PARENT，它似乎都将宽度和高度设置为 WRAP_CONTENT。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

I have used this solution for Dialog (not DialogFragment) and it works as expected:

我已将此解决方案用于 Dialog（不是 DialogFragment），它按预期工作：

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

this is perfect for me. when extends DialogFragmentoverride onCreateView()... impelments all logic

这对我来说是完美的。当扩展DialogFragment覆盖时onCreateView()......实现所有逻辑

dialog make it Full Screen just override this method

对话框使其全屏只需覆盖此方法

 @Override
public Dialog onCreateDialog(final Bundle savedInstanceState) {

    // the content
    final RelativeLayout root = new RelativeLayout(getActivity());
    root.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

    // creating the fullscreen dialog
    final Dialog dialog = new Dialog(getActivity());
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(root);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.YELLOW));
    dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

    return dialog;
}

The best solution I found was to set the width or minWidth to some arbitrarily large value to ensure it fills the screen. I don't like this solution, but I haven't seen anything better.

我发现的最佳解决方案是将宽度或 minWidth 设置为某个任意大的值以确保它填满屏幕。我不喜欢这个解决方案，但我没有看到更好的。

In my code, I was wanting a fullscreen dialog, but still show the notification bar at the top of the screen, so I'm using:

在我的代码中，我想要一个全屏对话框，但仍然在屏幕顶部显示通知栏，所以我正在使用：

setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_Black_NoTitleBar);

This makes it fullscreen, but I'm not using a fullscreen style so that I keep the notification bar.

这使其全屏显示，但我没有使用全屏样式，因此我保留了通知栏。

Hope it helps someone!

You can also do something like-

你也可以做类似的事情——

@Override
  public void onCreate(@Nullable final Bundle savedInstanceState) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
      setStyle(STYLE_NO_TITLE, android.R.style.Theme_Material_Light_NoActionBar_Fullscreen);
    } else {
      setStyle(STYLE_NO_TITLE, android.R.style.Theme_DeviceDefault_Light_NoActionBar);
    }
    super.onCreate(savedInstanceState);

  }

By this you will also be able to see the status bar colored for versions >= lollipop

通过这种方式，您还可以看到版本 >= 棒棒糖的颜色状态栏

To have a full screen dialog, you need use

要拥有全屏对话框，您需要使用

public class CustomDialogFragment extends DialogFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
        // Inflate the layout to use as dialog or embedded fragment
        return inflater.inflate(R.layout.purchase_items, container, false);
    }


    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        return dialog;
    }
}

And to show this dialog:

并显示此对话框：

CustomDialogFragment newFragment = new CustomDialogFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
// To make it fullscreen, use the 'content' root view as the container
// for the fragment, which is always the root view for the activity
fragmentManager.beginTransaction().add(android.R.id.content, newFragment).commit();

ATTENTION: You can't use following code to show the dialog, if not, the dialog will be shown in center of screen, not full screen.

注意：您不能使用以下代码来显示对话框，否则，对话框将显示在屏幕中央，而不是全屏。

//don't show dialog like this
newFragment.show(fragmentManager, "dialog");
