Answer 1

使用

 myListView.setOnItemSelectedListener(new OnItemSelectedListener(){
public void onItemSelected(AdapterView<?> listView, View view, int position, long id)

{ EditText yourEditText =（EditText）view.findViewById（R.id.youredittextid）; listView.setDescendantFocusability（ViewGroup.FOCUS_AFTER_DESCENDANTS）; yourEditText.requestFocus（）; } }）;

问题是选择行会占用焦点但是为了编辑EditText你需要关注它

ListItem中的Edittext在android中不可编辑
