java - 如何使DialogFragment全屏而不重叠状态栏/导航栏并保持状态栏颜色？

Question

我已经在谷歌上搜索了几个小时并尝试了无数的方法，但我就是无法让它发挥作用......

这是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);
        }
    }

}

这是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>

这几乎按照我的预期工作...唯一的问题是调用 window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT); 来填充整个屏幕(减去状态/导航栏)将状态栏颜色更改为黑色。当我关闭对话框时，它会变回 colorPrimaryDark。

如果我删除 window.setLayout(...) 行，状态栏将保留 colorPrimaryDark 但对话框大小将是默认值(一个小方 block )在屏幕中间)。

在我调用 window.setLayout(...) 的同一位置，我尝试放置以下代码:

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));
}

这会将状态栏颜色设置为 colorPrimaryDark，但它会与状态栏和导航栏重叠。

如果不重叠状态栏和导航栏并将 colorPrimaryDark 保留在状态栏上，我就无法获得全屏。

我发现了一些与同样问题有关的问题，但我无法让建议发挥作用。两者都没有公认的答案:

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

查看这个自定义的对话框 fragment ，尝试一下，它会满足您的需求。并让我知道。

 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);
}
}

根据您的需要更改对话框的大小。
