How to lose the focus of a edittext when "done" button in the soft keyboard is pressed?
提问by SSS
I have 7 edittext boxes in my xml. I'm using the OnFocusChangeListener to read the value from edittext and i'm using that value for my calculation.I want to make my edittext to lose its focus when i click on the done button in the soft keyboard.so that i can get the value in the edittext.

Call clearFocusmethod of EditTextto lose focus when done button is clicked from soft-keyboard. do it as:
从软键盘单击完成按钮时调用失去焦点的clearFocus方法EditText。这样做：
editText.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if(actionId==EditorInfo.IME_ACTION_DONE){
//Clear focus here from edittext
editText.clearFocus();
}
return false;
}
});
and also add android:imeOptions="actionDone"in edittext xml
并添加android:imeOptions="actionDone"edittext xml

If anyone comes across this question wondering how they could unfocus everything at oncein their activity, they can set the focus on the parent layout(or any layout for that matter).
如果有人遇到这个问题，想知道如何在他们的Activity 中一次性取消所有内容的焦点，他们可以将焦点设置在父布局（或任何与此相关的布局）上。
findViewById(R.id.myLayout).requestFocus();

Just a little more complete answer
只是更完整的答案
// This will change the ‘RETURN' button in your the EditText's soft keyboard to a ‘DONE' button.
editText.setImeOptions(EditorInfo.IME_ACTION_DONE);
// Use the InputMethodManager to close the soft keyboard
editText.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if(actionId==EditorInfo.IME_ACTION_DONE){
//Clear focus here from edittext
InputMethodManager imm = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
return false;
}
});

Kotlin, it worked for me:
Kotlin，它对我有用：
main.clearFocus()
main is a root ConstraintLayout
main 是一个根 ConstraintLayout
