Question

我正在尝试构建聊天界面。我已经编写了用于录制动画的代码用于fab.my问题是当我按下按钮并且我的edittext聚焦时，edittext无缘无故地失去了焦点，这隐藏了键盘中的自动检测字条，而Fab在上面键盘1厘米。我知道这个问题是由循环视图引起的，因为当我将回收器视图的可见性设置为Gone时，编辑文本在我尝试记录时不会失去焦点。我也尝试过更改windowSoftInputMode。谢谢您的帮助。

Answer 1

在你的onclick事件中

YOUR_EDITTEXT.requestFocus()

Answer 2

我找到了解决方案。我使用linearLayout包装了recyclerView，并且我禁用了焦点并阻止了后代。

   <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/input_holder"
    android:focusable="false"
    android:focusableInTouchMode="false"
    android:descendantFocusability="blocksDescendants"
    >
<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView_chat_item_list"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginEnd="5dp"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    android:layout_marginStart="5dp"
    android:clipToPadding="false"
    android:paddingTop="8dp"
    android:visibility="visible"
    app:layoutManager="LinearLayoutManager"
    tools:listitem="@layout/item_chat_list_out"

    />
</LinearLayout>

如果我按下录制按钮，EditText将失去焦点
