java - TouchWiz 启动器检测

Question

我目前正在 Android 中制作动态壁纸。事实证明，三星的 TouchWiz 启动器从未调用 onOffsetChanged 方法。这里唯一的方法是检测 TouchWiz 是否正在运行并相应地模拟滚动。有没有办法检测我的动态壁纸是否在三星的 TouchWiz 启动器下运行？

Answer 1

您可以使用下面示例中提供的代码来检测是否安装了启动器；

第一个

boolean isLauncherInstalled  () {
    final String myLauncherPackageName = "LAUNCHER PACKAGE NAME"; // com.sec.android.app.launcher

    final IntentFilter filterCategory = new IntentFilter(Intent.ACTION_MAIN);
    filter.addCategory(Intent.CATEGORY_HOME);

    List<IntentFilter> filters = new ArrayList<IntentFilter>();
    filters.add(filterCategory);

    List<ComponentName> activities = new ArrayList<ComponentName>();
    final PackageManager packageManager = (PackageManager) getPackageManager();

    packageManager.getPreferredActivities(filters, activities, null);

    for (ComponentName activity : activities) {
        if (myLauncherPackageName.equals(activity.getPackageName())) {
            return true; // Is a match so you have a Launcher installed. 
        }
    }
    return false; // No Launcher. 
}

第二个

public boolean isLauncherInstalled() {
    final String myLauncherPackageName = "LAUNCHER PACKAGE NAME"; // com.sec.android.app.launcher

    IntentFilter filterCategory = new IntentFilter(Intent.ACTION_MAIN);
    filterCategory.addCategory(Intent.CATEGORY_HOME);

    List<IntentFilter> filters = new ArrayList<IntentFilter>();
    filters.add(filterCategory);

    List<ComponentName> preferredActivities = new ArrayList<ComponentName>();
    final PackageManager packageManager = (PackageManager) getPackageManager();

    packageManager.getPreferredActivities(filters, preferredActivities, myLauncherPackageName);

    if (preferredActivities != null && preferredActivities.size()> 0) {
        return true; // Is a match so you have a Launcher installed.
    }
    return false; // No Launcher. 
}

但是，最好的选择是始终模拟滚动，因为有更多启动器不会触发 OnOffsetsChanged。但是，当您实际收到对 OnOffsetsChanged 的​​调用时，只需禁用模拟滚动即可。这样，如果可用，OnOffsetsChanged 就可以正常运行。
