Error message

More than one view in xml marked by qmui_layout_edge =

What it means

QMUIPullLayout.onFinishInflate throws when two children in the XML declare the same qmui_layout_edge (top/right/bottom/left). Each pull edge may host at most one action view; the duplicated edge name is appended to the message.

Solutions

  1. Ensure each qmui_layout_edge value (top/right/bottom/left) appears at most once among the direct children.
  2. Change the duplicated child to a different edge if you need actions on multiple sides.
  3. Remove the edge attribute from <include> roots that duplicate an already-declared edge.

Example fix

<!-- before -->
<View app:layout_qmui_layout_edge="top"/>
<View app:layout_qmui_layout_edge="top"/>
<!-- after -->
<View app:layout_qmui_layout_edge="top"/>
<View app:layout_qmui_layout_edge="bottom"/>
Defensive patterns

Strategy: validation

Validate before calling

// ensure each edge is used at most once
Set<Integer> seen = new HashSet<>();
for (int i = 0; i < pullLayout.getChildCount(); i++) {
    QMUIPullLayout.LayoutParams lp = (QMUIPullLayout.LayoutParams) pullLayout.getChildAt(i).getLayoutParams();
    if (!lp.isTarget && !seen.add(lp.edge)) {
        throw new IllegalStateException("duplicate qmui_layout_edge " + lp.edge);
    }
}

Try / catch

try {
    setContentView(R.layout.pull_screen);
} catch (RuntimeException e) {
    Log.e(TAG, "duplicate qmui_layout_edge in pull layout XML", e);
}

Prevention

When it happens

Trigger: Declaring two children with the same app:qmui_layout_edge value (e.g. both "top"), including duplicates introduced via <include> layouts inflated into the pull layout.

Common situations: Copy-pasting an action-view block (header/footer) in XML without changing its edge attribute; merging layouts where an included root already declares the same edge.
