java - 微调器 setSelection() 不起作用

Question

在我的代码中 spinnerObj.setSelection(count) 不起作用。我在谷歌中搜索它，但没有找到适合我的答案。

    count = 0;
    repairDetailsAdapter = new RepairDetailsAdapter(this, R.layout.gas_station_spinner_item, details);
    detailsOptionSpinner.setAdapter(repairDetailsAdapter);
    for (RepairDetail detail : details) {
        if (detail.getId() == tempDetail.getId()) {
            detailsOptionSpinner.setSelection(count);
            detailsOptionSpinner.invalidate();
            break;
        }
        count++;
    }

这行(来自 stackOverFlow)不起作用:

 final int finalCount = count;
new Handler().postDelayed(new Runnable() {
    public void run() {
        detailsOptionSpinner.setSelection(finalCount);
        detailsOptionSpinner.invalidate();
    }
}, 13);

Answer 1

您是否尝试过使用两个参数来设置微调器，第二个使用 boolean 值:

detailsOptionSpinner.setSelection(finalCount, true); 

来自developers page它显示:

setSelection(int position, boolean animate)
//Jump directly to a specific item in the adapter data.
