如何在充满数组的AutoCompletetextview中查找项目的位置

问题描述

我有一个数组( array1 和States)和AutoCompleteTextview，其中用 array1 填充它.当我从AutocompleteTextView中选择值时，我从AutoCompleteTextView Dropdown

I have an array (array1 with States) and AutoCompleteTextview in which I'm filling it with array1. When I select the value from AutocompleteTextView I select a state from AutoCompleteTextView Dropdown

我想要从我选择的 array1 中获得项目的位置.
我试过的是AutocompelteTextView的OnClickEvent.

What I want is to get the position of the item from array1 which I've selected.
What I've tried is OnClickEvent of AutocompelteTextView.

STATE.setOnItemClickListener(new OnItemClickListener(){

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {
        String selection = (String) parent.getItemAtPosition(position);
        String num = selection;
    }
});

这是给我从下拉列表中选择的值，但是我想在 array1 中获取position of the value.例如，我有一个大小为4的数组，例如array1 = {A，B，C，D}，如果我选择B，它将返回我在Array中的B位置，即2.

It ss giving me the value which I selected from dropdown but i want to get the position of the value in array1. For Example I have an array of size 4, like array1 = {A,B,C,D}, and if I select B it should return me B position in Array i.e 2.

我希望我说清楚了.预先感谢.

I hope I made it clear. Thanks in advance.

推荐答案

使用onItemClick中的 position 变量.

STATE.setOnItemClickListener(new OnItemClickListener(){

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {
        String selection = (String) parent.getItemAtPosition(position);
        int pos = -1;

        for (int i = 0; i < yourarray.length; i++) {
            if (yourarray[i].equals(selection)) {
                pos = i;
                break;
            }
        }
        System.out.println("Position " + pos); //check it now in Logcat
    }
});
