如何在不重叠状态栏/导航栏的情况下使对话片段全屏并保持状态栏颜色？

Question

我已经谷歌了几个小时，尝试了无数的东西，但我就是不能让这个工作...

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>

这几乎和我预期的一样…唯一的问题是调用window.setLayout（WindowManager.LayoutParams.MATCH_PARENT，WindowManager.LlayoutParams.MATCH_PAREN）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。

如果我删除了window.setLayout（…）行，状态栏将保留colorPrimaryDark，但对话框大小将是默认值（屏幕中间的一个小正方形）。

在我调用< code>window.setLayout(...)，我试着把下面的代码:

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颜色Primary黑暗，但它与状态栏和导航栏重叠。

我就是不能全屏显示，除非状态栏和导航条重叠，并保持< code>colorPrimaryDark在状态栏上。

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

• 带有半透明状态栏的全屏对话框片段
• Android全屏对话框片段如日历应用

Answer 1

根据材料设计指南创建全屏对话框。将此代码放入DialogFragment中：

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

通过以下方式调用此对话框:

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

在基础布局中将上边距设置为24dp。这样对话框就不会与状态栏重叠。

检查这个定制的对话片段，尝试它将满足您的需要。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);
}
}

根据需要更改对话框的大小。
