微调器工作但是没有图像..我找不到问题!! 私人Spinner UnitSpinner; ArrayAdapter UnitArray; ArrayAdapter UnitArrayadapter; private static UnitConverter实例;
这是我的可绘制内容，假设显示在微调器中
int arr_images[] = { R.drawable.area, R.drawable.ds, R.drawable.feul,
R.drawable.legnth, R.drawable.temp, R.drawable.time, R.drawable.temp, R.drawable.time};
@SuppressLint("ShowToast")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
我的微调器在这里
UnitSpinner = (Spinner)findViewById(R.id.UnitSpinner);
UnitSpinner.setOnItemSelectedListener(this);
UnitArray=new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item);
UnitArray.setDropDownViewResource(android.R.layout.simple_expandable_list_item_1);
UnitSpinner.setAdapter(UnitArray);
**微调器的项目**
UnitArray.add(getResources().getString(R.string.Temperature));
UnitArray.add(getResources().getString(R.string.Weight));
UnitArray.add(getResources().getString(R.string.Length));
UnitArray.add(getResources().getString(R.string.Power));
UnitArray.add(getResources().getString(R.string.Energy));
UnitArray.add(getResources().getString(R.string.Velocity));
UnitArray.add(getResources().getString(R.string.Area));
UnitArray.add(getResources().getString(R.string.Volume));
UnitArray.setNotifyOnChange(true);
UnitArrayadapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item);
UnitArrayadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
UnitArrayadapter.setNotifyOnChange(true);
