我如何触发一个动作，当用户按下回车键？

问题描述

如果（在Android中）我有一个EditText中，我怎么能触发事件，当用户完成数据输入和点击返回/下一页？

我用下面的code都试过，但它似乎没有任何效果。我也得到一个从类型新extView.OnEditorActionListener（该方法onEditorAction（EditText上，INT，KeyEvent的））{}从不在本地使用的错误。

  myEditText.setOnEditorActionListener（新EditText.OnEditorActionListener（）{
            公共布尔onEditorAction（的EditText V，INT actionId，KeyEvent的事件）{
                如果（actionId == EditorInfo.IME_ACTION_NEXT）
                {
 

解决方案

我打了一下周围的各种事物，发现下面的作品code：

  myEditText.setOnEditorActionListener（新OnEditorActionListener（）{
    @覆盖
    公共布尔onEditorAction（TextView的V，INT actionId，KeyEvent的事件）{
        //做一些东西
    }
}）;
 

If (in Android) I have an EditText box, how can I trigger an event when the user has finished entering data and hits return/Next?

I have tried using the code below but it seems to have no effect. I also get an 'The method onEditorAction(EditText, int, KeyEvent) from the type new extView.OnEditorActionListener(){} is never used locally' error.

myEditText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
            public boolean onEditorAction(EditText v, int actionId, KeyEvent event) {
                if (actionId == EditorInfo.IME_ACTION_NEXT)
                {

解决方案

I played around a bit with various things and found that the code below works:

myEditText.setOnEditorActionListener(new OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        // Do some stuff
    }
});
