如何让禁用的微调器看起来不被禁用？

Question

I have made a spinner and when there is only one item on it I want to disable it, but I don't like the grayish look the text gets when it's disabled. I already tried to use .setClickable(false); but it did not work. I have seen a lot of posts with the other way around having a disabled one with look different than the default one, but it didn't help me.
My code right now is:

if (list.size() > 1) {
    list.setlistNumber("Select a list");
    list.add(0, list);
    mListSpinner.setClickable(true);
    return list;
} else {
    mAccountSpinner.setEnabled(false);
    // mListSpinner.set;
    t = 1;

but I have no idea on how to get the Enable(false), look like a Enable(true) without being selectable.

I hope this will helpful to you.

In xml

           <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="80dp"
            android:gravity="center">

            <Spinner
                android:id="@+id/spinner"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_margin="5dp" />

            <LinearLayout
                android:id="@+id/layout"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="#00000000"
                android:clickable="false"
                android:orientation="vertical" />
        </RelativeLayout>

And In java:

This is my code, which I tested.

 List<String> list = new ArrayList<>();
    list.add("Please select a item");
    list.add("Item1");
    list.add("Item2");
    list.add("Item3");

    LinearLayout layout = (LinearLayout) findViewById(R.id.layout);

    ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_dropdown_item, list);

    Spinner spinner = (Spinner) findViewById(R.id.spinner);
    spinner.setAdapter(adapter);

    if (list.size() > 1) {
        layout.setClickable(false);
    } else {
        layout.setClickable(true);
    }

Just remove the listener in order not to do anything but keeping the default behaviour.

spinner.setOnClickListener(null);

If you want to enable the spinner again, just add once again the listener

spinner.setOnClickListener(myListener);

Answer 3

Override with a custom styled background with no disabled drawable.

   <Spinner
      ...
      android:background="@drawable/spinner_background"
      ...
   />

res/drawable/spinner_background.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- changed from apptheme_spinner_disabled_holo_light -->
<item android:state_enabled="false"
      android:drawable="@drawable/apptheme_spinner_default_holo_light" />
<item android:state_pressed="true"
      android:drawable="@drawable/apptheme_spinner_pressed_holo_light" />
<item android:state_pressed="false" android:state_focused="true"
      android:drawable="@drawable/apptheme_spinner_focused_holo_light" />
<item android:drawable="@drawable/apptheme_spinner_default_holo_light" />

The drawables will depend on the style of your app. You can generate new holo style drawables here for example.

As for the text colour, this should be very similar, adding a similar xml descriptor:-

   <Spinner
      ...
      android:textColor="@color/spinner_text"
      ...
   />

res/values/spinner_text.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:state_focused="true" android:color="@color/black"/>
   <item android:state_pressed="true" android:state_enabled="false" android:color="@color/black" />
   <item android:state_enabled="false" android:color="@color/black" />
   <item android:color="@color/black"/>
</selector>

not even sure if that is needed, you may be able to set the color directly:

       <Spinner
      ...
      android:textColor="#000000"
      ...
   />
