Umano SlidingPanel中状态栏下方的滑动布局 [英] Sliding layout below status bar in Umano SlidingPanel

问题描述

我已经使用 https://github.com/umano/AndroidSlidingUpPanel 实现了UmanoSlidingPanel。除了滑动面板展开后，滑动内容（sliding_view）移到状态栏下方，一切都正常。如何避免？我尝试删除

I have implemented UmanoSlidingPanel using https://github.com/umano/AndroidSlidingUpPanel . Everything is working fine except that my sliding panel when expanded, the sliding content (sliding_view) is going below the status bar. How can I avoid that?I tried removing

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

来自styles.xml，但这也使状态栏对于主要内容也不透明。有什么办法解决这个问题？

from styles.xml but that makes the status bar non-tranlucent for the main content also. Any way to fix this?

找到了解决该问题的另一种方法通过更改SlidingUpPanelLayout.java的onMeasure方法。将代码发布给以后的读者。需要添加4行代码。

Found another solution to the problem by making changes in onMeasure method of SlidingUpPanelLayout.java . Posting the code for future readers.Need to add 4 lines of code.

SlidingPanelLayout.java

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;
}
