Android OnKeyListener

Question

为什么我不能用参数View实现OnKeyListener， 例如参数是哪个例子 （View v，int keyCode，KeyEvent event）我被迫使用参数（ DialogInterface对话框，int keyCode，KeyEvent事件）而不是View as I想。

Answer 1

You need to delete the import statement at the top of your code and change it to the correct one. they probably both have the same same but are in different packages.

Delete

import android.content.DialogInterface.OnKeyListener;

Add

import android.view.View.OnKeyListener;
