获取启用/禁用状态和可访问性颜色反转模式

Question

在我的应用程序中，当用户启用可访问性颜色反转模式时，我需要进行一些 UI 更改。

我们是否有任何 API 可以检查 Android 中颜色反转模式的启用/禁用状态？

Answer 1

以下是检查可访问性反转模式的启用/禁用状态的代码。在某些手机中，反转模式将作为“负色”提供。

public boolean isInversionModeEnabled() {
    boolean isInversionEnabled =  false;
    int accessibilityEnabled = 0;
    try {
        accessibilityEnabled = Settings.Secure.getInt(this.getContentResolver(),
                android.provider.Settings.Secure.ACCESSIBILITY_DISPLAY_INVERSION_ENABLED);
    } catch (SettingNotFoundException e) {
        Log.d(TAG, "Error finding setting ACCESSIBILITY_DISPLAY_INVERSION_ENABLED: " + e.getMessage());
        Log.d(TAG, "Checking negative color enabled status");
        final String SEM_HIGH_CONTRAST = "high_contrast";
        accessibilityEnabled = Settings.System.getInt(getContentResolver(), SEM_HIGH_CONTRAST, 0);
    }
    if (accessibilityEnabled == 1) {
        Log.d(TAG, "inversion  or negative colour is enabled");
        isInversionEnabled = true;
    } else {
        Log.d(TAG, "inversion  or negative colour is disabled");
    }
    return isInversionEnabled;

}
