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.
