Question

我有两种适用于手机和平板电脑的布局，均来自单一代码。

...
<Spinner
            android:id="@+id/spin_font_sizes"
            android:layout_width="0px"
            android:layout_height="0px"
            android:entries="@array/lst_editor_font_sizes" />
...

在这两种布局中我都定义了一个隐藏的Spinner，以下代码适用于手机，但不适用于平板电脑：微调器显示在手机上，但点击它不会触发监听器事件。

spin_font_sizes=(Spinner)findViewById(R.id.spin_font_sizes);
        spin_font_sizes.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                            // THIS IS NOT CALLED ON PHONE!
                Resources res=getResources();
                String[] arr = res.getStringArray(R.array.lst_editor_font_sizes);
                float size= Float.parseFloat(arr[arg2]);
                editor.setTextSize(TypedValue.COMPLEX_UNIT_PT,size);
                SharedPreferences settings = getSharedPreferences("Abrar.Editor", 0);
                Editor edt = settings.edit();
                edt.putFloat("editorFontSize", size);
                edt.commit();
            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });

有时我在日志中看到此错误：

03-30 11:03:03.528: W/InputEventReceiver(8958): Attempted to finish an input event but the input event receiver has already been disposed.

平板电脑上未调用setOnItemSelectedListener
