两种选择样式：android:spinnerMode="dropdown"  下拉框样式android:spinnerMode="dialog"    弹窗样式

// 默认选择第一项 onItemSelected --> position == 0sp.setAdapter(new SpinnerStringAdapter(context, list));sp.setOnItemSelectedListener(listener);

// 选择最后一次设置的项 onItemSelected  --> position == 3(0-2的都不走)sp.setAdapter(new SpinnerStringAdapter(context, list));sp.setOnItemSelectedListener(listener);sp.setSelection(0);sp.setSelection(1);sp.setSelection(2);sp.setSelection(3);

// 设置监听顺序也无关 onItemSelected  --> position == 3(0-2的都不走)sp.setAdapter(new SpinnerStringAdapter(context, list));sp.setSelection(0);sp.setSelection(1);sp.setSelection(2);sp.setSelection(3);sp.setOnItemSelectedListener(listener);
