问题描述

我有一个EditText。当我点击它，它成为可获得焦点。我将输入的输入文字输入到的EditText。我想实现一个侦听器的EditText，所以，当我停止打字，电脑就会自动文本保存为一个按钮到数据库代替。如何有一个监听器的EditText听取了打字停止或不？

I have an EditText. When i click on it, it becomes focusable. I will type the input text to be entered into the EditText. I want to implement a listener for EditText, so that when i stop typing, it should automatically save that text into the database instead of having a button. How to have a listener for EditText to listen that typing is stopped or not?

推荐答案

设置的EditText imeOption

set edittext imeOption

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

通过使用这样的事情，

By using something like this,

editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            // Specify your database function here.
            return true;
        }
        return false;
    }
});

另外，你可以使用 OnEditorActionListener 接口，以避免匿名内部类。

Alternatively, you can use the OnEditorActionListener interface to avoid the anonymous inner class.
