启用ListView选择-安卓
启用ListView选择-安卓
提问于 2012-02-08 18:47:06
我遇到了奇怪的问题，我不能点击我的列表视图...我用和以前一样的方式实现了它，但问题是它不起作用。
listTags.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
listTags.setSelection(position);
Toast.makeText(getParent(), "hello", Toast.LENGTH_LONG).show();
}
});我正在扩展Activity类
我就是这样声明listview的
listTags = (ListView) viewToLoad.findViewById(R.id.listPack);这就是我在xml中做的事情。
<ListView
android:id="@+id/listPack"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginBottom="5dip"
android:layout_marginLeft="5dip"
android:layout_marginRight="5dip"
android:layout_weight="1" >
</ListView>这和任何地方一样正常，我不知道哪里出了问题，请帮我解决这个问题。
谢谢
听到适配器的代码
adapter = new KeywordAdapter(getApplicationContext(), id,
getLNApplication().getKeyworddetail());
listTags.setAdapter(adapter);我的KeywordAdapter类
public class KeywordAdapter extends BaseAdapter {
public KeywordAdapter(Context context, int id, ArrayList<ArrayList<Keyword>> keywordList) {
this.context = context;
if (id >= keywordList.size()) {
keyWordList = new ArrayList<Keyword>();
} else
keyWordList = keywordList.get(id);
}
// Implemented methods for BaseAdpter
public class ViewHolder {
TextView tagName;
//.... more code
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
View view = convertView;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.package_tag_details, null, true);
holder = new ViewHolder();
holder.tagName = (TextView) view.findViewById(R.id.tagName);
//.... more code
holder.layout = (LinearLayout) view
.findViewById(R.id.linearLayout1);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
holder.tagName.setText(keyWordList.get(position).getName());
ArrayList<Integer> rank = keyWordList.get(position).getRank();
@SuppressWarnings("unused")
holder.tagRank1.setText(rank.get(position));
//.... more code
return view;
}
public void forceReload() {
notifyDataSetChanged();
}

您放置在listView中的项目是什么，将所有项目设置为android:focusable="false"

只需在代码中更改以下内容即可。
listTags = (ListView)findViewById(R.id.listPack);你确定android:layout_width支持"match_parent“吗？请查看控制台。希望这对你有帮助。

我没有看到您设置适配器，即listTags.setAdapter(?);
Try this code (works for me):
// MainActivity
public class MainActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ListView listTags = (ListView) findViewById(R.id.listPack);
listTags.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item, mStrings));
listTags.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
listTags.setSelection(position);
// Toast.makeText(getParent(), "hello", Toast.LENGTH_LONG).show();
}
});
}
private String[] mStrings = {
"Comte", "Coolea", "Cooleney", "Coquetdale", "Corleggy", "Cornish Pepper",
"Cotherstone", "Cotija", "Cottage Cheese", "Cottage Cheese (Australian)",
"Cougar Gold", "Coulommiers", "Coverdale", "Crayeux de Roncq", "Cream Cheese",
"Cream Havarti", "Crema Agria", "Crema Mexicana", "Creme Fraiche", "Crescenza",
"Croghan", "Crottin de Chavignol", "Crottin du Chavignol", "Crowdie", "Crowley",
"Cuajada", "Curd", "Cure Nantais", "Curworthy", "Cwmtawe Pecorino",
};
