Android 设置动态壁纸没有确认按钮处理方式

使用反射设置壁纸，

// wallpaperManager.setWallpaperComponent(new ComponentName(context.getPackageName(), name));

如果需要设置壁纸跟随移动需要设置

// wallpaperManager.setWallpaperOffsetSteps(0.5f, 0.0f);
// wallpaperManager.setWallpaperOffsets(windowToken, 0.5f, 0.0f);

    /*** 通过反射设置动态壁纸** @param context* @param name*/private void setLiveWallpaper(Context context, String name) {try {Class<?> aClass = Class.forName(WallpaperManager.class.getName());Method setWallpaperComponent = aClass.getMethod("setWallpaperComponent", new Class[]{ComponentName.class});boolean susccess = (boolean) setWallpaperComponent.invoke(WallpaperManager.getInstance(context), new ComponentName(context.getPackageName(), name));Log.d(TAG, "setLiveWallpaper: " + susccess);} catch (ClassNotFoundException e) {Log.d(TAG, "ClassNotFoundException: " + e.toString());e.printStackTrace();} catch (NoSuchMethodException e) {Log.d(TAG, "NoSuchMethodException: " + e.toString());e.printStackTrace();} catch (IllegalAccessException e) {Log.d(TAG, "IllegalAccessException: " + e.toString());e.printStackTrace();} catch (InvocationTargetException e) {Log.d(TAG, "InvocationTargetException: " + e.toString());e.printStackTrace();}
//        wallpaperManager.setWallpaperComponent(new ComponentName(context.getPackageName(), name));
//        wallpaperManager.setWallpaperOffsetSteps(0.5f, 0.0f);
//        wallpaperManager.setWallpaperOffsets(windowToken, 0.5f, 0.0f);}

使用方法：

changePaper(context, GifWallpaperService.class.getCanonicalName());

GIF和video壁纸加载器参考下面：
