java - Android MaterialBetterSpinner 更改事件

Question

我想知道，当所选项目发生变化时，是否可以设置 MaterialBetterSpinner 的事件监听器？

类似的事情:

String [] TIPLIST = "Elektro","Oprema","Vodovod","Ogrevanje","Internet","Požarne naprave","Drugo"};
ArrayAdapter<String> arrayAdapterTip = new ArrayAdapter<String>(this,
        android.R.layout.simple_dropdown_item_1line,TIPLIST);
MaterialBetterSpinner tipSpinner = (MaterialBetterSpinner)findViewById(spinnerTipNapake);
        tipSpinner.setAdapter(arrayAdapterTip);

tipSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
//MaterialBetterSpinner changed
}

但是MaterialBetterSpinner似乎没有setOnItemSelectedListener。

Answer 1

MaterialBetterSpinner 没有 setOnItemSelectedListener。 相反，你可以使用这个:

 tipSpinner.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {
            spinnerValue=tipSpinner.getText().toString();
              Log.i("value", spinnerValue);

        }
    });
