我遇到了使用listview的問題,當我點擊它時什麼都沒有發生。我想爲它點擊列表視圖項目來做一個敬酒,所以我知道它正在被點擊。我一直在努力/研究一段時間,一無所獲。有人會介意看看我是否錯過了我剛剛忽略的一些東西嗎?提前謝謝了!listView項點擊事件沒有觸發
這裏是我的類:
public class MyCar extends Activity {
/**
* Called when the activity is first created.
*/
public ListView mylistView;
String carInfo;
private ArrayAdapter<String> mylistAdapter;
ArrayList<String> arrayListCar = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mycar);
mylistView = (ListView) findViewById(R.id.listView);
arrayListCar = new ArrayList<String>();
//Just had to remove setting this adapter 2 times. Took out line below to fix.
mylistView.setAdapter(mylistAdapter);
mylistView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
String item = ((TextView) view).getText().toString();
Toast.makeText(getBaseContext(), item, Toast.LENGTH_LONG).show();
}
});
}
@Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
carInfo = trySomethin();
fillList();
}
public void fillList() {
String make = "";
String model = "";
String[] pieces = carInfo.split("\"");
make = pieces[3];
model = pieces[7];
ArrayList<String> carList = new ArrayList<String>();
carList.add(make + " " + model);
// Create ArrayAdapter using the car list.
mylistAdapter = new ArrayAdapter<String>(MyCar.this, android.R.layout.simple_list_item_single_choice, carList);
mylistView.setAdapter(mylistAdapter);
mylistAdapter.notifyDataSetChanged();
}
}
你沒有看到「吐司」? – Raghunandan 2014-12-03 05:36:00
是的,我沒有看到烤麪包。當我點擊它時,列表視圖保持在那裏,我可以點擊它10次,什麼也沒有發生。 – Shawn 2014-12-03 05:36:16
哇,我很抱歉浪費時間,我沒有看到我將適配器設置爲mylistView 2次。刪除了onCreate中的一個,現在可以使用。感謝您的時間! – Shawn 2014-12-03 05:42:34
