键盘打开时，Recyclerview不会滚动到结尾 [英] Recyclerview not scrolling to end when keyboard opens

问题描述

我在应用程序中使用recylerview，并且每当将新元素添加到recyclerview时，它就会通过使用滚动到最后一个元素

I am using recylerview in my application and whenever new element is added to recyclerview, it scrolls to last element by using

recyclerView.scrollToPosition(adapter.getCount());

但是，每当键盘打开时(由于editTextView)，它都会调整视图的大小，并且recyclerview会变小，但无法滚动到最后一个元素.

But, whenever keyboard opens(because of editTextView), it resizes the view and recyclerview gets smaller, but couldn't scroll to last element.

android:windowSoftInputMode="adjustResize"

我什至试图用下面的代码滚动到最后一个元素，但是没有用

I even tried to used the following code to scroll to last element, but it didn't work

editTextView.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus){
                recyclerView.scrollToPosition(chatAdapter.getItemCount());
            }
        }
    });

我可以尝试adjustPan向上移动平移，但是它隐藏了我的工具栏. 请提出任何纠正问题的方法.

I can try adjustPan to shift the pan up, but it is hiding my toolbar. Please suggest any way to rectify the issue.

推荐答案

您可以使用recyclerview.addOnLayoutChangeListener()捕捉键盘上的更改. 如果bottom小于oldBottom，则键盘处于向上状态.

You can catch keyboard up changes using recyclerview.addOnLayoutChangeListener(). If bottom is smaller than oldBottom then keyboard is in up state.

if ( bottom < oldBottom) { 
   recyclerview.postDelayed(new Runnable() { 
       @Override 
       public void run() {
           recyclerview.smoothScrollToPosition(bottomPosition); 
       }
    }, 100);
}
