android - android EditText imeOption OnClick

Question

使用按钮很简单，

<Button 
    android:blablabla="blabla"
    ...
    android:onClick="doSomething" />

这将执行 doSomething(View) 函数。

我们如何使用 EditText 来模仿它？我已经读过这个，我读到大多数人使用一个 imeOptions （这似乎仍然是必要的），然后在那个 EditText 对象上实现一个 actionListener 。

这是我迷路了。有没有办法像使用 Button 一样实现从键盘到 onClick 函数的“完成”操作（或发送或...），或者我们需要显式实现侦听器？

问候 ！

当您按下Done软键盘中的键时，以下代码将执行一些操作。

editText.setOnEditorActionListener(new OnEditorActionListener() {        
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if(actionId==EditorInfo.IME_ACTION_DONE){
            //do your actions here that you like to perform when done is pressed
            //Its advised to check for empty edit text and other related 
            //conditions before preforming required actions
        }
    return false;
    }
});

希望能帮助到你 ！！

I am assuming what you are wanting to do is run some code when the EditText is clicked?

If so, I have found a solution from another thread on the site:

    EditText myEditText = (EditText) findViewById(R.id.myEditText);
    myEditText.setOnFocusChangeListener(new OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {

    then do this code here

    }
}
});
