问题 I have two spinners that second spinner's value depend on the first spinner. every item in spinner has an id that came from JSON . Now, I want to get second spinner's item id. I get selected item's name but I need name and id of the selected item. call.enqueue(new Callback<Map<String, ResponseJSON2>>() { @Override public void onResponse (Call<Map<String, ResponseJSON2>> call, retrofit2.Response<Map<String, ResponseJSON2>> response) { responseJson = response.body(); if (responseJson != null) {

问题 I have been able to save Integers and Strings as Shared Preferences but have searched and cannot seem to be able to save a Spinners selected value as a shared preference? spinner = (Spinner)findViewById(R.id.spnCalorieRange); adapter = ArrayAdapter.createFromResource(this, R.array.Calorie_Range, android.R.layout.simple_spinner_dropdown_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); spinner.setOnItemSelectedListener(new

问题 I have a spinner which drops down when a button is clicked. But when I am trying to set onItemSelectedListener, it is not taking the click events. spnrLocation.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View arg1, int arg2, long arg3) { System.out.println("location clicked" + arg2); edtLocation.setText(parent.getItemAtPosition(arg2).toString()); System.out.println("wfefe" + parent.getItemAtPosition(arg2).toString()); }

问题 I have a series of ToggleButtons which represent a series of topics. When toggled, the ToggleButton changes its background color to indicate its state. When in the checked state, the ToggleButton has a darker color. A Spinner overlays the ToggleButton and allows the user to select a difficulty for the topic. How do I change the text color (to white) of the Spinner when the ToggleButton is pressed? I think I can handle changing the spinner selector, but I'm struggling to work out a way to

问题 It was hard to write a proper topic for this issue. So, let me make myself clear. I'm making a local app, dealing with data containing Turkish letters (ĞÜŞİÖÇğüşıöç). Problem is, the industrial tablet I must use don't have those chars on its virtual keyboard. So I need to have a special AutoCompleteTextView which treats some letters as same. For example if the client enters "sener" to the text box, "şener" should be shown as a result in the dropdown too. Is there even a way I could achieve

问题 I'm trying to give a custom background to my spinner. I've downloaded the HTC sense spinner design (Cf. following pictures) with the 9 patch format. I've created a new XML file with the following code inside: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/spinner_pressed" /> <item android:state_focused="true" android:state_pressed="true"

问题 Is there anyway to add two text views or strings inside of the Actionbar Spinner? Similar to how the Android GMAIL app does it. 回答1: You could use a custom ArrayAdapter: public class spinnerAdapter extends ArrayAdapter { private LayoutInflater inflater; public spinnerAdapter(Context context, int textViewResourceId) { super(context, textViewResourceId); inflater = LayoutInflater.from(context); } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder

问题 I have working activity with 12 spinners that are linked to a single database table of over 20,000 records. Each spinner is bound to a different query to make the selections dynamic (based upon the prior selections). The code works but I'm having awful performance due to the number of queries and size of the table in the database. The initial layout takes 20+ seconds to load. That is because the first spinner is set to an initial selection during the layout which causes the 11 other spinners

问题 I am able to save one spinner as shared preferences using Spinner not saving as Shared/Saved Preference. However I need multiple spinners to be interlinked and I am having issues when i try to save them and I am not sure why. Here is how my spinners are linked. The first Spinner enables second spinner when it is selected. spinner = (Spinner)findViewById(R.id.spnMondayExercise); adapter = ArrayAdapter.createFromResource(this, R.array.Exercise, android.R.layout.simple_spinner_dropdown_item);
