如何实现可选择复制但不可编辑的多行EditText？

Hey there! I’ve dealt with this exact scenario before, so let me break down the reliable solutions for you. The issue with your initial textMultiLine|none approach is that none maps to InputType.TYPE_NULL, which forces the EditText into single-line mode—exactly why your multi-line behavior broke.

Here are two solid ways to get a multi-line, selectable-but-uneditable EditText:

Solution 1: XML + Code (Recommended for Compatibility) #

First, set up your EditText in XML with the multi-line input type, then disable editing via code while preserving selectability:

XML Layout #

<EditText
    android:id="@+id/readOnlyMultiLineEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textMultiLine"
    android:scrollbars="vertical" <!-- Optional: adds scroll for long content -->
    android:text="Your multi-line text here\nSecond line of content\nThird line to test wrapping" />

Java Code #

EditText readOnlyEditText = findViewById(R.id.readOnlyMultiLineEditText);
// Disable editing while keeping selectability
readOnlyEditText.setKeyListener(null);
// Ensure long press brings up copy/select menu
readOnlyEditText.setLongClickable(true);
// Optional: Hide cursor if you don't want it visible
readOnlyEditText.setCursorVisible(false);

Kotlin Code #

val readOnlyEditText = findViewById<EditText>(R.id.readOnlyMultiLineEditText)
readOnlyEditText.keyListener = null
readOnlyEditText.isLongClickable = true
readOnlyEditText.isCursorVisible = false // Optional

Solution 2: Pure XML (Simpler, Note Compatibility) #

You can also use XML attributes directly, though note that android:editable is marked as deprecated (but still works on most devices):

<EditText
    android:id="@+id/readOnlyMultiLineEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textMultiLine"
    android:editable="false"
    android:longClickable="true"
    android:scrollbars="vertical"
    android:text="Multi-line content\nthat's easy to select\nbut impossible to edit" />

Why This Works #

• textMultiLine keeps the line-wrapping and multi-line behavior intact.
• Disabling the key listener (or using editable="false") prevents any text input.
• longClickable="true" ensures users can trigger the text selection menu to copy content.
