我的目标是将选定的微调项目字符串的一部分显示为选定的项目。在微调器选项中，我想显示完整的字符串，但选择时仅显示其第一部分。示例:
选择:“赛车”> 显示:“赛车”，
选择:“快车” > 显示:“快”
这可能吗？我的代码:
private void defineRacingCarsArray(){
racingCarsArray = Arrays.asList(
"Racing Car",
"Fast Car"
);
}
private void defineRacingCarsCodeSpinner(){
racingCarsCodeSpinner = (Spinner) view.findViewById(R.id.cars_code_spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getContext(), android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
for (int i = 0; i < racingCarsArray.size(); ++i) {
adapter.add(racingCarsArray.get(i));
}
racingCarsCodeSpinner.setAdapter(adapter);
racingCarsCodeSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
parent.getItemAtPosition(position);
String car = racingCarsArray.get(position);
;
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
最佳答案
试试这个，
racingCarsCodeSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// here you have to update
TextView selectedView = (TextView) view;
selectedView.setText(racingCarsArray.get(position).split(" ",2)[0]);
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
