Question

我有一个在运行时创建控件的片段，首先创建一个微调器，然后是第二个，第二个微调器中的细节依赖于第一个选择。我可以根据第一个微调器的选择来更新第二个微调器的数据吗？

<div id="value"> </div> <div id="prueba"> ABCDE </div>

你可以做这样的事情

Spinner firstSpinner = (Spinner) findViewById(R.id.first_spinner);
// You can set your first spinner values here if not set already, and then
firstSpinner.setOnItemSelectedListener(onFirstSpinnerChange(firstSpinner));

进一步添加此

AdapterView.OnItemSelectedListener onFirstSpinnerChange(Spinner mySpinner) {
    return new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            // You can add this method to set the values of the second spinner in your activity
            // You can use the position, or alternatively selectedItemView for this purpose to identify the selected item
            setSecondSpinnerBasedOnFirstOnePositionSelected();

            // Or you can just set your spinner in this block
        }

        @Override
        public void onNothingSelected(AdapterView<?> parentView) {
            // do nothing
        }
    };
}
