android - 检测我的无障碍服务是否启用

Question

我想知道如何检测我自己的服务是否已启用。所以我可以检查我的服务是否未启用，然后告诉用户启用它。

Answer 1

以下是检查您的无障碍服务是否启用的方法。 

注意：YOURAccessibilityService使用您的服务 更改值。

// To check if service is enabled
private boolean isAccessibilitySettingsOn(Context mContext) {
    int accessibilityEnabled = 0;
    final String service = getPackageName() + "/" + YOURAccessibilityService.class.getCanonicalName();
    try {
        accessibilityEnabled = Settings.Secure.getInt(
                mContext.getApplicationContext().getContentResolver(),
                android.provider.Settings.Secure.ACCESSIBILITY_ENABLED);
        Log.v(TAG, "accessibilityEnabled = " + accessibilityEnabled);
    } catch (Settings.SettingNotFoundException e) {
        Log.e(TAG, "Error finding setting, default accessibility to not found: "
                + e.getMessage());
    }
    TextUtils.SimpleStringSplitter mStringColonSplitter = new TextUtils.SimpleStringSplitter(':');

    if (accessibilityEnabled == 1) {
        Log.v(TAG, "***ACCESSIBILITY IS ENABLED*** -----------------");
        String settingValue = Settings.Secure.getString(
                mContext.getApplicationContext().getContentResolver(),
                Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES);
        if (settingValue != null) {
            mStringColonSplitter.setString(settingValue);
            while (mStringColonSplitter.hasNext()) {
                String accessibilityService = mStringColonSplitter.next();

                Log.v(TAG, "-------------- > accessibilityService :: " + accessibilityService + " " + service);
                if (accessibilityService.equalsIgnoreCase(service)) {
                    Log.v(TAG, "We've found the correct setting - accessibility is switched on!");
                    return true;
                }
            }
        }
    } else {
        Log.v(TAG, "***ACCESSIBILITY IS DISABLED***");
    }

    return false;
}

并调用此方法：

if (!isAccessibilitySettingsOn(getApplicationContext())) {
    startActivity(new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS));
}

如果未启用，这将检查并启动可访问性设置。

这是Jakub Bláha在 java 中的答案的修改版本。

public boolean isAccessServiceEnabled(Context context, Class accessibilityServiceClass)
{
    String prefString = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES);

    return prefString!= null && prefString.contains(context.getPackageName() + "/" + accessibilityServiceClass.getName());
}

Answer 3

这在某种程度上是一个较小的版本，但它正在工作。

fun isAccessServiceEnabled(context: Context): Boolean {
    val prefString =
        Settings.Secure.getString(context.contentResolver, Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES)
    return prefString.contains("${context.packageName}/${context.packageName}.${context.getString(R.string.access_service_name)}")
}

如果有什么遗漏，请随时纠正我。

Kotlin 版本基于@Pankaj Kumar 的回答

inline fun <reified T> Context.isAccessibilityEnabled(): Boolean {
    var enabled = 0
    try {
        enabled = Settings.Secure.getInt(contentResolver, Settings.Secure.ACCESSIBILITY_ENABLED)
    } catch (e: SettingNotFoundException) {
        Timber.e(e)
    }
    if (enabled == 1) {
        val name = ComponentName(applicationContext, T::class.java)
        val services = Settings.Secure.getString(contentResolver, Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES)
        return services?.contains(name.flattenToString()) ?: false
    }
    return false
}

1：基于 Kotlin 的答案 2：添加了当前包名称检查，因为仅当为当前包启用可访问性服务时，它才会返回 true，最近，如果启用了任何包可访问性服务，则返回 true

  private fun checkAccessibilityPermission(): Boolean {
            var isAccessibilityEnabled = false
            (requireActivity().getSystemService(Context.ACCESSIBILITY_SERVICE) as AccessibilityManager).apply {
                installedAccessibilityServiceList.forEach { installedService ->
                    installedService.resolveInfo.serviceInfo.apply {
                        if (getEnabledAccessibilityServiceList(AccessibilityServiceInfo.FEEDBACK_ALL_MASK).any { it.resolveInfo.serviceInfo.packageName == packageName && it.resolveInfo.serviceInfo.name == name && permission == Manifest.permission.BIND_ACCESSIBILITY_SERVICE && it.resolveInfo.serviceInfo.packageName == requireActivity().packageName })
                            isAccessibilityEnabled = true
                    }
                }
            }
            if (isAccessibilityEnabled.not())
                startActivity(Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS).apply {
                    flags = Intent.FLAG_ACTIVITY_NEW_TASK
                })
            return isAccessibilityEnabled
        }
