如何在 Android 上制作 EditText,这样用户可能不会输入多行文本,但显示仍然是多行的(即,有自动换行而不是向右移动的文本)?
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)?
类似于内置短信应用,我们不能输入换行符,但文本显示为多行.
It's similar to the built-in SMS application where we can't input newline but the text is displayed in multiple lines.
我将子类化小部件并覆盖键事件处理以阻止 Enter
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);
}
}
