本文探讨了如何在Android系统中获取默认桌面、输入法和动态壁纸的接口方法，详细阐述了相关API的使用和实现步骤。

获取默认桌面

public Set<String> getDefaultLaunchers() {
    Set<String> defaultLaunchers = new HashSet<String>();
    PackageManager packageManager = getPackageManager();
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    // 查询所有已安装的桌面应用
    List<ResolveInfo> launcherList = packageManager.queryIntentActivities(intent,
            PackageManager.MATCH_DEFAULT_ONLY);
    // 获取默认的桌面应用，没有指定默认桌面时返回"android"
    ResolveInfo defaultLauncher = packageManager.resolveActivity(intent,
            PackageManager.MATCH_DEFAULT_ONLY);
    if (launcherList != null && defaultLauncher != null) {
        String pkgName = defaultLauncher.activityInfo.packageName;
        System.out.println("zyf default launcher is : " + pkgName);
        // 没有指定默认桌面时返回的是“android”，故这里过滤下防止“android”被添加到默认桌面列表中
        for (ResolveInfo info : launcherList) {
            System.out.println("zyf launcher : " + info.activityInfo.packageName);
            if (info.activityInfo.packageName.equals(pkgName)) {
                defaultLaunchers.add(pkgName);
            }
        }
    }
    // 有多个桌面应用，且目前没有指定默认桌面时，返回所有的桌面应用
    if (defaultLaunchers.isEmpty() && launcherList != null) {
        for (ResolveInfo resolveInfo : launcherList) {
            defaultLaunchers.add(resolveInfo.activityInfo.packageName);
        }
    }
    System.out.println("zyf defaultLaunchers : " + defaultLaunchers);
    return defaultLaunchers;
}

获取默认输入法

public String getDefaultInputMethod() {
    String defaultInputMethod = null;
    String inputComponent = Settings.Secure.getString(getContentResolver(),
            Settings.Secure.DEFAULT_INPUT_METHOD);
    if (!inputComponent.isEmpty()) {
        System.out.println("zyf input method is : " + inputComponent);
        // 获取的结果是：com.sohu.inputmethod.sogouoem/.SogouIME，故需要截取一下字符串
        defaultInputMethod = inputComponent.substring(0, inputComponent.indexOf("/"));
    }
    return defaultInputMethod;
}

获取默认动态壁纸

public String getDefaultLiveWallper() {
    String defaultWallper = null;
    WallpaperManager wallpaperManager = WallpaperManager.getInstance(getApplicationContext());
	// 当前设置的是动态壁纸则返回相关信息，静态壁纸则返回null
    WallpaperInfo wallpaperInfo = wallpaperManager.getWallpaperInfo();
    if (wallpaperInfo != null) {
        defaultWallper = wallpaperInfo.getPackageName();
    }
    System.out.println("zyf default wallpaper is : " + defaultWallper);
    return defaultWallper;
}
