滑动Umano SlidingPanel状态栏下方的布局

标签: android android-layout android-sliding

我使用https://github.com/umano/AndroidSlidingUpPanel实现了UmanoSlidingPanel。一切都工作得很好,除了我的滑动面板扩展时,滑动内容(sliding_view)低于状态栏。我怎么能避免这种情况?我试着删除

 <item name="android:windowTranslucentStatus">true</item> 
来自styles.xml的

但是这也使主要内容的状态栏不是半透明的。有什么方法可以解决这个问题吗?

<com.sothree.slidinguppanel.SlidingUpPanelLayout xmlns:sothree="http://schemas.android.com/apk/res-auto"
    android:id="@+id/sliding_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="bottom"
    sothree:umanoDragView="@+id/firstPanelDragArea"
    sothree:umanoPanelHeight="@dimen/bottom_panel_height"
    sothree:umanoShadowHeight="4dp">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <include
            android:id="@+id/toolbar"
            layout="@layout/toolbar" />

        <FrameLayout
            android:id="@+id/frame_container"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>

    <!-- SLIDING LAYOUT -->
    <LinearLayout
        android:id="@+id/firstPanelDragArea"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <include layout="@layout/sliding_view" />

    </LinearLayout>

styles.xml

 <style name="AppTheme" parent="@style/Theme.AppCompat">
    <item name="windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowTranslucentNavigation">true</item>
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:windowTranslucentStatus">true</item>
    <item name="windowNoTitle">true</item>
</style>

修改

  public void onPanelSlide(View panel, float slideOffset) {
              if (slideOffset > 0.5 && !flagTransparent) {
                getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
                getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
                flagTransparent = true;
                Log.i(TAG, "onPanelSlide, offset " + slideOffset);
            } else if (slideOffset < 0.5 && flagTransparent){
                getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
                getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
                flagTransparent = false;
                Log.i(TAG, "onPanelSlide, offset " + slideOffset);
  }

1)看看我创建的以下Gist

文件sliding_up_activity.xml可以是包含向上滑动面板视图的活动布局。 在那里你应该设置android:fitsSystemWindows="true",以便任何孩子都能正确插入,而不是落在操作栏或导航栏后面。

文件sliding_view.xml可能是您的向上滑动视图。

您不需要在任何面板回调中执行任何其他操作。

您可以安全地删除onPanelSlide()内的半透明样式和代码。这应该导致滑动面板正确插入,以便永远不会落后于状态或导航栏。

或者,如果您没有相同的架构,则可以忘记sliding_up_activity.xml并在android:fitsSystemWindows="true"中设置CoordinatorLayout,而不是sliding_view.xml

2)我们谈论的第二件事是使状态栏保持半透明状态,让滑动面板落在状态栏后面,然后平滑地添加填充以正确插入内容。 为此,请设置android:fitsSystemWindows="false"或将其从您的向上滑动面板的任何可能的父级中移除。 然后在onPanelSlide你可以做这样的事情

    if (slideOffset >= ANCHOR_POINT) {
        // adjust the span of the offset
        float offset = (slideOffset - ANCHOR_POINT) / (1 - ANCHOR_POINT);
        // the padding top will be the base original padding plus a percentage of the status
        // bar height
        float paddingTop = mSlidePanelBasePadding + offset * mStatusBarInset;
        // apply the padding to the header container
        mContainer.setPadding(0, (int) paddingTop, 0, 0);
    }

其中:

  • mSlidePanelBasePadding将是您向上滑动面板的初始填充
  • mStatusBarInset将是状态栏高度。

当它越过锚点时,应该逐步向slideUp面板添加填充。

您可以像这样获取状态栏高度:

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

我希望这有点帮助。

通过在SlidingUpPanelLayout.java的onMeasure方法中进行更改,找到了另一个问题的解决方案。为未来的读者发布代码。需要添加4行代码。

SlidingPanelLayout.java

 @Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    final int widthMode = MeasureSpec.getMode(widthMeasureSpec);
    final int widthSize = MeasureSpec.getSize(widthMeasureSpec);
    final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
    final int heightSize = MeasureSpec.getSize(heightMeasureSpec);

    if (widthMode != MeasureSpec.EXACTLY) {
        throw new IllegalStateException("Width must have an exact value or MATCH_PARENT");
    } else if (heightMode != MeasureSpec.EXACTLY) {
        throw new IllegalStateException("Height must have an exact value or MATCH_PARENT");
    }

    final int childCount = getChildCount();

    if (childCount != 2) {
        throw new IllegalStateException("Sliding up panel layout must have exactly 2 children!");
    }

    mMainView = getChildAt(0);
    mSlideableView = getChildAt(1);
    if (mDragView == null) {
        setDragView(mSlideableView);
    }

    // If the sliding panel is not visible, then put the whole view in the hidden state
    if (mSlideableView.getVisibility() != VISIBLE) {
        mSlideState = PanelState.HIDDEN;
    }

    int layoutHeight = heightSize - getPaddingTop() - getPaddingBottom();
    int layoutWidth = widthSize - getPaddingLeft() - getPaddingRight();

    // First pass. Measure based on child LayoutParams width/height.
    for (int i = 0; i < childCount; i++) {
        final View child = getChildAt(i);
        final LayoutParams lp = (LayoutParams) child.getLayoutParams();

        // We always measure the sliding panel in order to know it's height (needed for show panel)
        if (child.getVisibility() == GONE && i == 0) {
            continue;
        }

        int height = layoutHeight;
        int width = layoutWidth;
        if (child == mMainView) {
            if (!mOverlayContent && mSlideState != PanelState.HIDDEN) {
                height -= mPanelHeight;
            }

            width -= lp.leftMargin + lp.rightMargin;
        } else if (child == mSlideableView) {
            // The slideable view should be aware of its top margin.
            // See https://github.com/umano/AndroidSlidingUpPanel/issues/412.
 //                height -= lp.topMargin;.
 // START OF CODE CHANGES
            if (height < SCREEN_HEIGHT) {  //SCREEN_HEIGHT = 900
                height = height - MARGIN_BOTTOM; //MARGIN_BOTTOM = 8
            } else {
                height = height - getStatusBarHeight();
            }
 // END OF CODE CHANGES
        }


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

在父版式中尝试android:fitsSystemWindows="true"。这应该可以解决你的问题。

我过去实现的另一个解决方案是,在包含slidingUpPanel的活动中,您可以使用半透明状态栏(API&gt; = 19)对其进行样式设置:

<item name="android:windowTranslucentStatus">true</item>

然后在onPanelSlide回调中,您可以修改slideUpPanel的填充,逐步添加,直到面板完全启动。在那一刻,添加的额外填充量应该是状态栏尺寸。
