监听AutoCompleteTextView？

Question

我有一个显示在AutoCompleteTextView中的项目数组，我想加载附加到AutoCompleteTextView中选择的值的html

所以我尝试使用OnItemSelected但没有任何反应

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_horarios);

        mytext = findViewById(R.id.displayResult);

        actv_grupos = (AutoCompleteTextView)findViewById(R.id.actv_grupos);

        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
                R.array.array_grupos, android.R.layout.simple_dropdown_item_1line);
        actv_grupos.setAdapter(adapter);
        actv_grupos.setOnItemSelectedListener(this);


    }

itemSelected函数

    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

        String grupo = (String) parent.getItemAtPosition(position);

        if(position != 0) {
            abrirUrl(grupo);

        }

    }

Answer 1

使用OnItemSelected()内的setOnItemClickListener()进行解决，如下所示：

actv_grupos.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

         String grupo = (String) parent.getItemAtPosition(position);

         if(position != 0) {
             abrirUrl(grupo);
         }
});
