我开始学习安卓了。我有问题。我有 autocompleteTextView,内容是 arrayList。然后我想在单击 autoCompleteTextView 时获取元素在 arraylist 中的位置。你能教我做吗?
太感谢了 !
这段代码!
/* ================= looping through All categories ==================== */
for(int i=0;i<product.length();i++){
JSONObject c = product.getJSONObject(i);
// Storing each json item in variable
pro_id = c.getString(TAG_ID);
pro_name = c.getString(TAG_NAME);
name_product.add(pro_name);
} // end for products
} catch (JSONException e) {
e.printStackTrace();
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, name_product);
AutoCompleteTextView textView = (AutoCompleteTextView)findViewById(R.id.result_search);
textView.setThreshold(1);
textView.setAdapter(adapter);
textView.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {
//here position is your selected item id
/*String selecteditem =name_product.get(position);
Log.d("Test",selecteditem.toString());
int pos = Integer.parseInt(selecteditem);
Toast.makeText(getApplicationContext(), "cvxcvcv",pos).show();*/
// I want to get position when i click element in autocompletetextView
}
});
