問題描述

我有這個 EditText

I have this EditText

<EditText
    android:layout_width="match_parent"
    android:layout_height="72dp"
    android:hint="@string/write_message"
    android:textColorHint="@color/primary_color"
    android:ems="10"
    android:imeOptions="actionDone"
    android:inputType="textImeMultiLine"
    android:id="@+id/message_input"
    android:layout_gravity="center_horizontal"
    android:backgroundTint="@color/primary_color"/>

當框被用戶輸入的文本填滿時，它會向右滾動以為更多文本騰出空間，我不喜歡這種行為，如果 EditText 框在需要更多空間時向上擴展，我更喜歡它?有沒有辦法做到這一點?謝謝.

When the box is filled up with user inputted text, it scrolls to the right to make room for more text, I do not like this behavior, and would prefer it if the EditText box expanded upwards when it needs more room? Is there a way to do this? Thanks.

推薦答案

是的，這實際上涉及到兩件事:

Yes, this actually involves two things:

1. 使 EditText 接受多行輸入.
2. 隨著更多文本行的添加，其高度會增加.

因此，要實現這一點，您需要設置:

Therefore, to achieve this, you need to set up:

android:inputType="textMultiLine"
android:layout_height="wrap_content"

(請注意 textMultiLine 和 textImeMultiLine).

(Be mindful of the difference between textMultiLine and textImeMultiLine).

完整的 XML 片段是:

The full XML snippet would be:

<EditText
    android:layout_width="match_parent"
    android:inputType="textMultiLine"
    android:layout_height="wrap_content"
    android:hint="@string/write_message"
    android:textColorHint="@color/primary_color"
    android:ems="10"
    android:imeOptions="actionDone"
    android:id="@+id/message_input"
    android:layout_gravity="center_horizontal"
    android:backgroundTint="@color/primary_color"/>
