Question

我在PreferenceActivity中使用SwitchPreference。当我使用SwitchCompat更改开关样式以匹配Lollipop样式时，触摸窗口小部件（显示动画）不会更改SwitchPreference值，而触摸文本列表（无动画）会更改值。

我在Android冰淇淋设备中使用Android支持AppCompat-v7：23.1.1，它适用于Lollipop设备。

这是我的 preference.xml

<SwitchPreference
    android:defaultValue="false"
    android:key="enable stock"
    android:summary="POS can display and decrease stock if any transaction occurred"
    android:title="Enable stock" />

这里 SettingsActivity.java 中的 onCreateView（）方法使用Lollipop样式，使用 SwitchCompat（）方法

@Override
public View onCreateView(String name, Context context, AttributeSet attrs) {
    // Allow super to try and create a view first
    final View result = super.onCreateView(name, context, attrs);
    if (result != null) {
        return result;
    }

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
        // If we're running pre-L, we need to 'inject' our tint aware Views in place of the
        // standard framework versions
        switch (name) {
            case "EditText":
                return new AppCompatEditText(this, attrs);
            case "Spinner":
                return new AppCompatSpinner(this, attrs);
            case "CheckBox":
                return new AppCompatCheckBox(this, attrs);
            case "RadioButton":
                return new AppCompatRadioButton(this, attrs);
            case "CheckedTextView":
                return new AppCompatCheckedTextView(this, attrs);
            case "Switch":
                return new SwitchCompat(this, attrs);
        }
    }
}

有什么问题？

我和你有同样的问题。现在我修好了。只需禁用点击它即可。

@Override
    public View onCreateView(String name, Context context, AttributeSet attrs) {
        // Allow super to try and create a view first
        final View result = super.onCreateView(name, context, attrs);
        if (result != null) {
            return result;
        }

        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
            // If we're running pre-L, we need to 'inject' our tint aware Views in place of the
            // standard framework versions
            switch (name) {
                case "EditText":
                    return new AppCompatEditText(this, attrs);
                case "Spinner":
                    return new AppCompatSpinner(this, attrs);
                case "CheckBox":
                    return new AppCompatCheckBox(this, attrs);
                case "RadioButton":
                    return new AppCompatRadioButton(this, attrs);
                case "CheckedTextView":
                    return new AppCompatCheckedTextView(this, attrs);
                case "Switch":
                    SwitchCompat switchCompat = new SwitchCompat(this, attrs);
                    switchCompat.setFocusableInTouchMode(false);
                    switchCompat.setClickable(false);
                    switchCompat.setFocusable(false);
                    return switchCompat;

            }
        }

        return null;
    }

触摸SwitchCompat小部件不会更改SwitchPreference值
