////////////Code to Hide SoftKeyboard on Enter (DONE) Press///////////////
editText.setRawInputType(InputType.TYPE_CLASS_TEXT|InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD|InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

public boolean onEditorAction(TextView v, int actionId, KeyEvent event)

// Capture soft enters in a singleLine EditText that is the last EditText
// This one is useful for the new list case, when there are no existing ListItems
editText.clearFocus();
InputMethodManager inputMethodManager = (InputMethodManager) getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);
}
else if (actionId == EditorInfo.IME_ACTION_NEXT) {
// Capture soft enters in other singleLine EditTexts
} else if (actionId == EditorInfo.IME_ACTION_GO) {
} else {
// Let the system handle all other null KeyEvents
return false;
}
}
else if (actionId == EditorInfo.IME_NULL) {

// They supply a zero actionId and a valid keyEvent rather than
// a non-zero actionId and a null event like the previous cases.
if (event.getAction() == KeyEvent.ACTION_DOWN) {
// We capture the event when the key is first pressed.
} else {
// We consume the event when the key is released.

// To use this, do NOT set inputType on the EditText in the layout
fun EditText.setMultiLineCapSentencesAndDoneAction() {
imeOptions = EditorInfo.IME_ACTION_DONE
setRawInputType(InputType.TYPE_TEXT_FLAG_CAP_SENTENCES or InputType.TYPE_TEXT_FLAG_MULTI_LINE)
}
edittext.inputType = EditorInfo.TYPE_TEXT_FLAG_MULTI_LINE
edittext.setHorizontallyScrolling(false)
edittext.maxLines = Integer.MAX_VALUE // Or your preferred fixed value
我经常需要这样做,所以这样做是为了保持代码的整洁:
fun EditText.multilineIme(action: Int) {
imeOptions = action
inputType = EditorInfo.TYPE_TEXT_FLAG_MULTI_LINE
setHorizontallyScrolling(false)
maxLines = Integer.MAX_VALUE
}
// Then just call
edittext.multilineIme(EditorInfo.IME_ACTION_DONE)
如果你想在“完成”上添加一个可选的自定义操作,试试这个:
fun EditText.multilineDone(callback: (() -> Unit)? = null) {
val action = EditorInfo.IME_ACTION_DONE
multilineIme(action)
setOnEditorActionListener { _, actionId, _ ->
if (action == actionId) {
callback?.invoke()
true
}
false
}
}
}
// Then you can call
edittext.multilineDone { closeKeyboard() }
// or just
edittext.multilineDone()
