android-studio - Android 动态壁纸LayoutParams问题

Question

最近在做一个动态壁纸项目，我在Engine的onCreate方法里，去添加两只“蝴蝶”时，我使用了addView(imageview,new LayoutParams(width,height))方法，但是无论我怎么改变width和height，“蝴蝶”的大小都没有发生变化。我在网上查了下，貌似方法的使用是没有问题的，那么我应该怎么去调整imageview 的大小？

这个是效果图，下面是设置的代码：

LinearLayout.LayoutParams ivBlueParams=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
                    LinearLayout.LayoutParams.WRAP_CONTENT);
            ivBlueParams.gravity= Gravity.CENTER;

            LinearLayout.LayoutParams ivYellowParams=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
                    LinearLayout.LayoutParams.WRAP_CONTENT);
            widgetGroup.addView(ivYellowButterfly,ivYellowParams);
            widgetGroup.addView(ivBlueButterfly,ivBlueParams);

Answer 1

You should set ivYellowButterfly与ivBlueButterfly的setLayoutParams()或者获取ivYellowButterfly与ivYellowButterfly的LayoutParams to set it up.
