为 EditText 实现文本观察器

问题描述

我有一个 EditText.当我点击它时，它变得可聚焦.我将键入要输入到 EditText 中的输入文本.我想为 EditText 实现一个监听器，这样当我停止输入时，它应该自动将该文本保存到数据库中，而不是有一个按钮.如何让 EditText 的监听器来监听输入是否停止?

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

set edittext imeOption

set edittext imeOption

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

通过使用这样的东西，

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;
    }
});

或者，您可以使用 OnEditorActionListener 接口来避免匿名内部类.

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