在我的代码spinnerObj.setSelection(count)中不行。我在谷歌搜索它,但没有找到答案。

    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);

答案 0 :(得分:3)

您是否尝试使用两个参数设置微调器,第二个使用布尔值:

detailsOptionSpinner.setSelection(finalCount, true); 

从它显示的developers page

setSelection(int position, boolean animate)
