我的应用程序上有正常运行的搜索界面。现在,我试图使每个搜索结果列表项都可单击并显示在新活动中。我已经使它们可单击,但是我不知道如何将ListAdapter
值(记录)传递到onItemClick
方法中。
到目前为止,这是我的代码:
private void showResults(String query) {
Cursor cursor = DBHelper.searchDB(query);
startManagingCursor(cursor);
String[] searchFrom = new String[] { DBAdapter.KEY_MAKE,
DBAdapter.KEY_YEAR, DBAdapter.KEY_MAKE,
DBAdapter.KEY_MODEL };
int[] displayHere = new int[] { R.id.rDateTV, R.id.rYearTV,
R.id.rMakeTV, R.id.rModelTV };
final SimpleCursorAdapter records = new SimpleCursorAdapter(this,
R.layout.record_2, cursor, searchFrom, displayHere);
setListAdapter(records);
DBHelper.close();
// --- Click on list item ---
ListView clickList = getListView();
clickList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//--- here's the problem: how do I pass the ListAdapter values into onItemClick. the below doesn't like .getText()
String sYear = (view.findViewById(R.id.rYearTV)).getText().toString();
String sMake = (view.findViewById(R.id.rMakeTV)).getText().toString();
String sModel = (view.findViewById(R.id.rModelTV)).getText().toString();
// -- then pass these strings to an intent to launch a new activity
}
});
// --- END click on list item ----
}
有任何想法吗?我是这里的菜鸟,所以如果您可以向我展示代码,那将是AWSOME!
最佳答案
在OnItemClickListener.onItemClick
中,调用parent.getItemAtPosition(position)
。该方法返回设置到给定位置的光标。然后从该光标获取数据。不要关闭OnItemClickListener.onItemClick
内的光标。
例如:
ListView clickList = getListView();
clickList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Cursor c = (Cursor)parent.getItemAtPosition(position)
String sMake = c.getString(c.getColumnIndexOrThrow(DBAdapter.KEY_MAKE));//get data from cursor
...
}
});
