我如何在Android上一个EditText,使得用户不能输入多行文本,但显示效果还是多行(即有自动换行,而不是文字去到正确的)?
How do I make an EditText on Android such that the user may not enter a multi-line text, but the display is still multi-line (i.e. there is word-wrap instead of the text going over to the right)?
它类似于内置的,我们可以不输入新行,但文字会显示在多行的短信应用程序。
It's similar to the built-in SMS application where we can't input newline but the text is displayed in multiple lines.
我会继承窗口小部件并覆盖关键事件处理,以阻止输入键:
I would subclass the widget and override the key event handling in order to block the Enter
key:
class MyTextView extends EditText
{
...
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if (keyCode==KeyEvent.KEYCODE_ENTER)
{
// Just ignore the [Enter] key
return true;
}
// Handle all other keys in the default way
return super.onKeyDown(keyCode, event);
}
}
