似乎我无法将requestFocus放在TextInputEditText内，因为它会在预览屏幕上出现渲染问题并显示此堆栈跟踪：

以下Java代码适用于我：

TextInputEditText tEdit = ( TextInputEditText ) findViewById(...);
tEdit.requestFocus(); // (java)

<requestFocus() /> //not work for TextinputEditText in xml.

答案 1 :(得分：0)

只需将TextInputEditText用TextInputLayout包装，然后将<requestFocus />标记添加到TextInputLayout，就可以解决问题。

所以您的XML看起来像这样-

<com.google.android.material.textfield.TextInputLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <com.google.android.material.textfield.TextInputEditText
        android:layout_width="match_parent"
        android:imeOptions="actionDone"
        android:layout_height="wrap_content"/>

   <requestFocus />
</com.google.android.material.textfield.TextInputLayout>
