如何在不重叠状态栏/导航栏和状态栏颜色的情况下使DialogFragment全屏显示？

Question

I've been googling for hours and tried countless things but I just can't get this to work...

This is MyFragment.java :

public class MyFragment extends DialogFragment {

    public MyFragment() {
        // Required empty public constructor
    }

    public static MyFragment newInstance() {
        MyFragment newFragment = new LoginDialogFragment();
        newFragment.setCancelable(false);
        return newFragment;
    }

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new Dialog(getActivity(), R.style.MyAppTheme_Dialog);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_my, container, false);
        ButterKnife.bind(this, view);
        return view;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        Window window = getDialog().getWindow();

        if (window != null) {
            window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
            window.setWindowAnimations(R.style.MyAppTheme_Dialog);
        }
    }

}

And this is styles.xml :

<style name="MyAppTheme" parent="PreferenceFixTheme.Light.NoActionBar">
    <item name="android:windowBackground">@color/background</item>
    <item name="android:colorBackground">@color/background</item>
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary_dark</item>
    <item name="colorAccent">@color/accent</item>
    <item name="preferenceCategory_marginBottom">0dp</item>
</style>

<style name="MyAppTheme.Dialog">
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:windowBackground">@null</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowEnterAnimation">@anim/slide_up</item>
    <item name="android:windowExitAnimation">@anim/slide_down</item>
    <item name="android:windowFrame">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
</style>

This almost works as I expect it... The only problem is that calling window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT); to fill the whole screen (minus the status/navigation bars) changes the status bar color to black. When I close the dialog, it changes back to colorPrimaryDark .

If I remove that window.setLayout(...) line, the status bar will keep the colorPrimaryDark but the dialog size will be the default (a small square on the middle of the screen).

In the same place I call window.setLayout(...) , I tried putting the following code:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
    getWindow().setStatusBarColor(ContextCompat.getColor(getActivity, R.color.primary_dark));
}

This sets the status bar color to colorPrimaryDark but it overlaps both the status and navigation bar.

I just can't get fullscreen without overlapping the status and navigation bars and keep colorPrimaryDark on the status bar.

A few questions I've found with the same problem but I couldn't get the suggestions to work. Neither have an accepted answer:

• Fullscreen DialogFragment with translucent StatusBar
• Android full screen dialog fragment like calendar app

check this customized dialog fragment, try it which will satisfy your need . and let me know.

 import android.content.pm.ActivityInfo;
 import android.content.res.Configuration;
 import android.graphics.Point;
 import android.os.Build;
 import android.os.Bundle;
 import android.support.v4.app.DialogFragment;
 import android.util.TypedValue;
 import android.view.Display;

/**

public class _DialogFragment extends DialogFragment {
  @Override
  public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
  //   preventScreenRotation();
  }

  @Override
  public void onDestroy() {
    // releaseScreenRotation();
    super.onDestroy();
}

@SuppressWarnings("deprecation")
@Override
public void onStart() {
    super.onStart();

    // change dialog width
    if (getDialog() != null) {

        int fullWidth = getDialog().getWindow().getAttributes().width;
        int fullHeight = getDialog().getWindow().getAttributes().height;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
            Display display =    getActivity().getWindowManager().getDefaultDisplay();
            Point size = new Point();
            display.getSize(size);

            fullWidth = size.x;
            fullHeight = size.y;
        } else {
            Display display = getActivity().getWindowManager().getDefaultDisplay();
            fullWidth = display.getWidth();
            fullHeight = display.getHeight();
        }

        final int padding = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 0, getResources()
                .getDisplayMetrics());

        int w = fullWidth - padding;
        int h = fullHeight - (padding * 2);

        getDialog().getWindow().setLayout(w, h);
    }
}


 private void preventScreenRotation() {
     if (getResources().getConfiguration().orientation ==  Configuration.ORIENTATION_PORTRAIT) {
                getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
     } else {  
      getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
  }

  private void releaseScreenRotation() {
      getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
}
}

change the size of the dialog depends on your need.

Answer 2

To create a fullscreen dialog according to Material design guidelines. Put this code in the DialogFragment:

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

Call this dialog by:

getSupportFragmentManager().beginTransaction().add(android.R.id.content, FullScreenDialog.newInstance()).addToBackStack(null).commit();

Set the top margin to 24dp in the base layout. So that the dialog doesn't overlap the statusbar.
