How to disable cursor positioning and text selection in an EditText? (Android)
提问by Louis
I'm searching for a way to prevent the user from moving the cursor position anywhere. The cursor should always stay at the end of the current EditText value. In addition to that the user should not be able to select anything in the EditText. Do you have any idea how to realize that in Android using an EditText?
我正在寻找一种方法来防止用户将光标位置移动到任何地方。光标应始终停留在当前 EditText 值的末尾。除此之外，用户不应该能够在 EditText 中选择任何内容。您知道如何在 Android 中使用 EditText 实现这一点吗？
To clarify: the user should be able to insert text, but only at the end.
澄清：用户应该能够插入文本，但只能在最后。

I had the same problem. This ended up working for me:
我有同样的问题。这最终对我有用：
public class CustomEditText extends EditText {
@Override
public void onSelectionChanged(int start, int end) {
CharSequence text = getText();
if (text != null) {
if (start != text.length() || end != text.length()) {
setSelection(text.length(), text.length());
return;
}
}
super.onSelectionChanged(start, end);
}
}

This will reset cursor focus to the last position of the text
这会将光标焦点重置到文本的最后一个位置
editText.setSelection(editText.getText().length());
This method will disable cursor move on touch
此方法将禁用触摸时光标移动
public class MyEditText extends EditText{
@Override
public boolean onTouchEvent(MotionEvent event)
{
final int eventX = event.getX();
final int eventY = event.getY();
if( (eventX,eventY) is in the middle of your editText)
{
return false;
}
return true;
}
}
And You can use either the xml attribute
你可以使用 xml 属性
android:cursorVisible
android:cursorVisible
or the java function
或 java 函数
setCursorVisible(boolean)
setCursorVisible（布尔值）

It sounds like the best way to do this is to make your own CustomEditTextclass and override/modify any relevant methods. You can see the source codefor EditTexthere.
听起来最好的方法是创建自己的CustomEditText类并覆盖/修改任何相关方法。你可以看到源代码，为EditText在这里。
public class CustomEditText extends EditText {
@Override
public void selectAll() {
// Do nothing
}
/* override other methods, etc. */
}
