Java 全屏对话框片段与状态栏重叠

我创建了一个全屏对话框

问题是，我的工具栏与状态栏重叠，我不知道如何解决这个问题

对话框片段

    @Inject
    CreateAccountViewModel viewModel;

    @Override

                DataBindingUtil.inflate(inflater, R.layout.create_account_dialog_fragment, container, false);
        binding.setViewModel(viewModel);
        return binding.getRoot();
    }

    private void createToolbar(View rootView) {
        Toolbar toolbar = (Toolbar) rootView.findViewById(R.id.toolbar);

        // Set an OnMenuItemClickListener to handle menu item clicks
        toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
            @Override

编辑

从v21样式中删除StatusBarTransparency后，看起来是这样的

删除状态栏的透明颜色后，我发现现在可以添加填充，而状态栏不会变白

我的DialogFragment的

RelativeLayout

现在如下所示

 <RelativeLayout
      android:paddingTop="24dp"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="@android:color/background_light">

app/src/main/res/values-v21/styles.xml

<resources>>
      <style name="AppTheme.NoActionBar">
          <item name="windowActionBar">false</item>
          <item name="windowNoTitle">true</item>
          <item name="android:windowDrawsSystemBarBackgrounds">true</item>

          <!-- REMOVE THIS LINE 
          <item name="android:statusBarColor">@android:color/transparent</item>
          -->
      </style>
  </resources>

除了Nexus 5，我还没有在其他设备上测试过这个问题。

问题出在事务中。添加（containerId，fragment）部分

您已将其设置为：

transaction.add（android.R.id.content，fragment）

，是将其设置为android.R.id.content导致重叠

相反，将其设置为调用活动中父级内容框架的id

例如，在我的代码中，主活动父布局是一个抽屉布局，id为drawer_布局，因此我的修复是

 MyDialogFragment fragment = new MyDialogFragment ();
 FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
 transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
 transaction.add(R.id.drawer_layout, frag)
            .addToBackStack(null).commit();

---

如果您希望DialogFragment全屏显示，并且希望statusbar具有您自己的颜色，您可以在DialogFragment的onCreate（）方法中添加此选项

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

您还可以在onCreateView方法中为状态栏颜色添加以下代码

 getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
 getDialog().getWindow().setStatusBarColor(getResources().getColor(R.color.colorPrimaryDark));

---

如果可以，请包括您的

布局/toolbar.xml

。@AlexTownsend包括在内，谢谢您的注意。您的活动布局是否使用

FitsystemWindows=“true”

任何地方？@AlexTownsend不，如果我添加

FitsystemWindows=“true”

工具栏向下滑动，但状态栏只是一个白色空白条检查是否有

values/styles-v21/styles.xml

行

@android:color/transparent

。如果有的话，也可以尝试删除它。很好，

clearfags

对我很有效，但是

setStatusBarColor

不适用（Android 9）。
