Question

我有三个编辑文本字段。在这些字段中，我想仅为第一个字段显示软输入键盘，为后两个字段禁用这些字段，这些是日期和时间字段。

Edit-Text 1 //Show the keyboard
Edit-Text 2 and 3 //Hide the keyboard

通过使用下面的代码，我可以禁用字段2和3的键盘，但是当用户将焦点放在字段1上时，键盘会出现但当用户点击字段2或3时不会隐藏。虽然首先点击字段2或3，但不会出现键盘。

//Code to disable soft input keyboard
public static void disableSoftInputFromAppearing(EditText editText) {
    if (Build.VERSION.SDK_INT >= 11) {
        editText.setRawInputType(InputType.TYPE_CLASS_TEXT);
        editText.setTextIsSelectable(true);
    } else {
        editText.setRawInputType(InputType.TYPE_NULL);
        editText.setFocusable(true);
    }

如果软键盘已经打开，我怎么能隐藏它？

Answer 1

// 活动

public static void hideSoftKeyboard(Activity activity) {

   InputMethodManager inputMethodManager = (InputMethodManager)activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
   inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
 }

// 片段

public void hideSoftKeyboard() {
    InputMethodManager inputMethodManager = (InputMethodManager) getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
    inputMethodManager.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);
}

// 如果编辑文本失去焦点，隐藏键盘

edTxtMessage.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (isEditable){
                v.setFocusable(true);
                v.setFocusableInTouchMode(true);
            } else {
                edTxtMessage.setFocusable(false);
            }

            return false;
        }
    });

edTxtMessage.setOnFocusChangeListener(new View.OnFocusChangeListener({
        @Override
        public void onFocusChange(View view, boolean b) {
            if (!b){
                hideKeyboard(getContext(), view);
            }
        }
    });

private void hideKeyboard(Context context, View view) {
    if (view != null) {
        InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
}

Answer 2

简单的方法是使用xml

users: [
 {
   "name": "name1",
   "phone": "111111111",
   "address": "address1",
   "city": "city1",
   "pcap": 1111,
   "note": ""
 },
 {
   "name": "name2",
   "phone": "222222222",
   "address": "address2",
   "city": "city2",
   "pcap": 2222,
   "note": ""
 },
 {
   "name": "name3",
   "phone": "333333333",
   "address": "address3",
   "city": "city3",
   "pcap": 3333,
   "note": ""
 },
 {
   "name": "name4",
   "phone": "44444444",
   "address": "address4",
   "city": "city4",
   "pcap": 4444,
   "note": ""
 }
]

Answer 3

您可以将两个属性设置为edittext

  android:focusable="false"
  android:focusableInTouchMode="false"

注意：这样您的edittext可以点击日期和时间不会聚焦到软键盘

Answer 4

检查当前焦点是否不为null，否则可能导致null指针异常

if (getCurrentFocus() != null) {
        InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
        inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
}

如果Android软键盘处于打开状态，请将其隐藏
