带有半透明状态栏的 Android 4.4 上的 NavigationDrawer 边距

Question

在 Android 4.4 上，当使用带有 ActionBarCompat 和 NavigationDrawer 的半透明状态栏选项时，NavigationDrawer 列表视图与 ActionBar 略有重叠。它适用于我测试过的所有其他 API 级别。

据我所知，这是因为marginTop 选项从屏幕顶部而不是操作栏顶部（状态栏底部）开始。 状态栏的底部。有一个偏移量

有解决方法吗？我正在使用示例布局并将marginTop 当前设置为?attr/actionBarSize。

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout_drawer"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- As the main content view, the view below consumes the entire
     space available using match_parent in both dimensions. -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- android:layout_gravity="start" tells DrawerLayout to treat
     this as a sliding drawer on the left side for left-to-right
     languages and on the right side for right-to-left languages.
     The drawer is given a fixed width in dp and extends the full height of
     the container. A solid background is used for contrast
     with the content view. -->
    <ListView
        android:id="@+id/drawer_list"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_marginTop="?attr/actionBarSize"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="@drawable/bg_app" />
</android.support.v4.widget.DrawerLayout>

Answer 1

按照此处的代码进行操作 - https://github.com/afollestad/kitkat-transparency-demo

这让您可以设置半透明状态和导航栏，以及 NavigationDrawer。

如下覆盖 NavigationDrawer 中的 onViewCreated -

@Override
  public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) return;
    SystemBarTintManager tintManager = new SystemBarTintManager(getActivity());
    SystemBarTintManager.SystemBarConfig config = tintManager.getConfig();
    view.setPadding(0, config.getPixelInsetTop(true), config.getPixelInsetRight(), config.getPixelInsetBottom());
  }

这是假设您正在使用 SystemBarTint 库

最后，我不得不找到状态栏高度并手动设置边距。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
  DrawerLayout.LayoutParams lp = (DrawerLayout.LayoutParams) mDrawerList.getLayoutParams();
  lp.setMargins(0, lp.topMargin + getStatusBarHeight(), 0, 0);
  mDrawerList.setLayoutParams(lp);
}

public int getStatusBarHeight() {
  int result = 0;
  int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
  if (resourceId > 0) {
    result = getResources().getDimensionPixelSize(resourceId);
  }
  return result;
}
