java - 全屏DialogFragment不适合屏幕

Question

我正在尝试制作一个对话框 fragment 以适合屏幕尺寸，但问题是我得到了这个结果:MainActivity DialogScreenShot

正如您所看到的，该对话框不太适合 Activity ，我已经尝试了很多方法，但没有任何运气。这就是我调用对话框的方式:

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            FragmentManager fragmentManager = getSupportFragmentManager();
            EventDialog newFragment = new EventDialog();
            FragmentTransaction transaction = fragmentManager.beginTransaction();
            transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
            transaction.add(android.R.id.content, newFragment).addToBackStack(null).commit();
        }
    });

这是对话框 fragment 类:

public class EventDialog extends DialogFragment {

public static final String TAG = "Event";

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.event_dialog_layout, container, false);
    Toolbar toolbar = (Toolbar) rootView.findViewById(R.id.toolbar);
    toolbar.setTitle("New Event");

    ((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);

    ActionBar actionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();
    if (actionBar != null) {
        actionBar.setDisplayHomeAsUpEnabled(true);
        actionBar.setHomeButtonEnabled(true);
        actionBar.setHomeAsUpIndicator(R.drawable.ic_close_white_24dp);
    }
    setHasOptionsMenu(true);
    return rootView;
}

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

    return dialog;
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    menu.clear();
    inflater.inflate(R.menu.event_dialog_menu, menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == R.id.action_save) {
        // handle confirmation button click here
        return true;
    } else if (id == android.R.id.home) {
        // handle close button click here
        dismiss();
        return true;
    }

    return super.onOptionsItemSelected(item);
}

这是布局 xml 文件:

<android.support.design.widget.CoordinatorLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay"
    android:fitsSystemWindows="false">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/AppTheme.AppBarOverlay" />

</android.support.design.widget.AppBarLayout>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Your content here" />

</LinearLayout>

你知道为什么会发生这种情况吗？

我的目标是制作一个全屏 Material 设计对话框

谢谢!

在 Eventdialog 类的 onResume() 中，您可以像这样设置 fragment 的高度和宽度 -

 public void onResume() {

        super.onResume();
        WindowManager.LayoutParams params = getDialog().getWindow().getAttributes();
        params.width = RelativeLayout.LayoutParams.MATCH_PARENT;
        params.height = RelativeLayout.LayoutParams.MATCH_PARENT;
        params.gravity = Gravity.CENTER;
        getDialog().getWindow().setAttributes(params);



    }

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.event_dialog_layout, container, false);
    Toolbar toolbar = (Toolbar) rootView.findViewById(R.id.toolbar);
    toolbar.setTitle("New Event");

    ((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);

    ActionBar actionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();
    if (actionBar != null) {
        actionBar.setDisplayHomeAsUpEnabled(true);
        actionBar.setHomeButtonEnabled(true);
        actionBar.setHomeAsUpIndicator(R.drawable.ic_close_white_24dp);
    }
    setHasOptionsMenu(true);
    return rootView;
}
