问题 I need to find the height of android ListView with custom ListVAdapter. Each of ListView items can be of varying height. I have tried the following code which I found here: public static void setListViewHeightBasedOnChildren(ListView listView) { ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) { return; } int totalHeight = 0; for (int i = 0; i < listAdapter.getCount(); i++) { View listItem = listAdapter.getView(i, null, listView); listItem.measure(0, MeasureSpec

问题 I have a XML layout which has two edit text fields, one for "title" and the the other for "story". When the user enters his data in these text fields and presses the back button the entry gets saved in a list view as the title set. The list view is present in an activity say A1.

问题 I have a simple LinearLayout with ListView inside it ( match_parent both for width and height). I need a context menu to show up upon a long touch on ANY place in the ListView. First, I called registerForContextMenu for the ListView. This makes the context menu show up ONLY if the touch is performed on a list item. Then I called registerForContextMenu for the LinearLayout as well, and set it attribute android:longClickable="true" . This did not help. So the question is how can one produce a
