我在片段中只创建了工具栏。我已经实现了多个删除列表视图的操作模式。但是动作模式将在工具栏（即）操作栏上方打开。如何在工具栏上显示该操作模式我在我的主题中尝试了<item name="windowActionModeOverlay">true</item>，但它不起作用。

答案 0 :(得分：0)
试试这个。
android.view.ActionMode mMode = toolbar.startActionMode(new Callback() {
@Override
public boolean onPrepareActionMode(
ActionMode mode, Menu menu) {
return false;
}
@Override
public void onDestroyActionMode(
ActionMode mode) {
}
@Override
public boolean onCreateActionMode(
ActionMode mode, Menu menu) {
return false;
}
@Override
public boolean onActionItemClicked(
ActionMode mode, MenuItem item) {
return false;
}
});
如果你想 Fininsh 动作模式
if (mMode != null) {
mMode.finish();
}
不要忘记在styles.xml
<item name="android:windowActionModeOverlay">true</item>
你很高兴。
