        @Bind(R.id.tv_like_count)
        TextView tvLikecount;
        @Bind(R.id.tv_comment_count)
        TextView tvCommentcount;


        public MyViewHolder(View view) {
            super(view);
            ButterKnife.bind(this, view);
        }
    }
}

当用户喜欢或评论特定的提要时，我调用 fragment 类方法来更新它，并且我在应用程序中显示 friend 的提要。当我显示个别 friend 的提要时，这会造成泄漏关于如何解决这个问题的任何想法。任何帮助都是应用

Answer 1

您应该在焦点窗口消失时释放 mNextServedView(例如 onStop 或 onDestory)。

代码如下:

   InputMethodManager methodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
    try {
        Field mNextServedView = methodManager.getClass().getDeclaredField("mNextServedView");
        mNextServedView.setAccessible(true);
        mNextServedView.set(methodManager, null);

        Field mServedView = methodManager.getClass().getDeclaredField("mServedView");
        mServedView.setAccessible(true);
        mServedView.set(methodManager, null);

        Method method = methodManager.getClass().getDeclaredMethod("finishInputLocked");
        method.setAccessible(true);
        method.invoke(methodManager);
    } catch (Throwable e) {
        e.printStackTrace();
    }
