NumberPicker에서 소프트 키보드 비활성화

NumberPicker에서 소프트 키보드 비활성화

---

NumberPicker를 사용하여 숫자 값을 입력 할 때 (미학적 이유로) 소프트 키보드를 비활성화하려고합니다. 이것은 내 레이아웃 XML 코드입니다.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@+id/linearLayout2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginBottom="30dp"
        android:layout_marginTop="30dp" >

        <NumberPicker
            android:id="@+id/repetitionPicker"
            android:layout_width="40dp"
            android:layout_height="wrap_content" />

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:text="@string/repetitions_short_divider"
            android:textAppearance="?android:attr/textAppearanceMedium" />

        <NumberPicker
            android:id="@+id/weightPicker"
            android:layout_width="40dp"
            android:layout_height="wrap_content"
            android:layout_marginLeft="40dp" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:text="@string/pounds"
            android:textAppearance="?android:attr/textAppearanceMedium" />
    </LinearLayout>


    <Button
        android:id="@+id/saveButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:text="@string/save" />

</LinearLayout>

마지막으로 이것은 onCreate () 메소드에서 키보드를 차단하려고하는 코드입니다.

// hide keyboard
View.OnClickListener disableKeyBoardListener = new View.OnClickListener() {
    public void onClick(View v) {
        ((InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE))
                .hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    }
};

((EditText) weightPicker.getChildAt(1)).setInputType(InputType.TYPE_NULL);
((EditText) repetitionPicker.getChildAt(1)).setInputType(InputType.TYPE_NULL);

((EditText) weightPicker.getChildAt(1)).setOnClickListener(disableKeyBoardListener);
//((EditText) repetitionPicker.getChildAt(1)).setOnClickListener(disableKeyBoardListener);
//weightPicker.setOnClickListener(disableKeyBoardListener);
//repetitionPicker.setOnClickListener(disableKeyBoardListener);     

getWindow().setSoftInputMode(
        WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); 

슬프게도 NumberPicker를 클릭하면 소프트 키보드가 계속 나타납니다. 어떤 아이디어?

방금 이것을 발견했으며 매력처럼 작동합니다.

myNumberPicker.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS);

이것을 XML로 설정할 수도 있습니다 :

android:descendantFocusability="blocksDescendants"

Andrew Webber의 답변의 Xml 버전

android:descendantFocusability="blocksDescendants"

예

<NumberPicker
        android:id="@+id/your_numberpicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:descendantFocusability="blocksDescendants"/>

com / android / internal / widget / NumberPicker.java 소스 코드를 읽은 후 다음 해결책을 얻었습니다.

// Hide soft keyboard on NumberPickers by overwriting the OnFocusChangeListener
OnFocusChangeListener fcl = new OnFocusChangeListener() {
    public void onFocusChange(View v, boolean hasFocus) {
        // Do nothing to suppress keyboard
    }
};

((EditText) numberPicker.getChildAt(1)).setOnFocusChangeListener(fcl);

// Suppress soft keyboard from the beginning
((EditText) numberPicker.getChildAt(1)).setInputType(InputType.TYPE_NULL);

@MaxVogler의 답변을 향상 시켰으므로 (이 투표에서 @MaxVogler도 투표하고 싶다면) 강력한 해킹으로 만드십시오. 또한 우리는 호출 할 필요성을 해달라고 setOnFocusChangeListener하고 setInputType. setFocusable거짓으로 만 할 것입니다.

아래는 기능을 활성화 / 비활성화하는 도우미 API입니다.

public static void enableNumberPickerManualEditing(NumberPicker numPicker,
        boolean enable) {
    int childCount = numPicker.getChildCount();

    for (int i = 0; i < childCount; i++) {
        View childView = numPicker.getChildAt(i);

        if (childView instanceof EditText) {
            EditText et = (EditText) childView;
            et.setFocusable(enable);
            return;
        }
    }
}

Here's another way to do it which enables the user still to edit a number if they want to - it just suppresses the soft keyboard initially. Use NumberPicker.setDescendantFocusability(FOCUS_BLOCK_DESCENDANTS) to suppress the soft keyboard when the interface first shows as per answers above. Then get your dialog or activity to implement View.OnTouchListener, call setOnTouchListener(this) on your NumberPicker, and in your implementation of onTouch(View v,MotionEvent e) reset the numberpicker descendant focusability to its normal value, then return false.

Returning false means that the touch is still processed by the NumberPicker, which means that if the user taps the edit box the soft keyboard comes up. This happens to be exactly what I wanted faced with the same problem - having the soft keyboard come up with the dialog when it first shows is displeasing as it shifts the dialog up after it appears.

public class GetBufferDialog extends DialogFragment implements View.OnTouchListener {

after creating the Dialog in the onCreateDialog() method and finding the NumberPicker:

m_oldFocus = m_numberpicker.getDescendantFocusability();
m_numberpicker.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS); 
m_numberpicker.setOnTouchListener(this);

and here's the OnTouch method:

public boolean onTouch(View v, MotionEvent event) {
    m_numberpicker.setDescendantFocusability(m_oldFocus);
    return false;
}

The simplest I found to work was :

numberPicker               = (NumberPicker) myDialogView.findViewById(R.id.myViewId);
EditText numberPickerChild = (EditText) numberPicker.getChildAt(0);
numberPickerChild.setFocusable(false);
numberPickerChild.setInputType(InputType.TYPE_NULL);

If you only want to hide the software keyboard when loading the view with your number picker, but still want the users to be able to edit after the view loads, then you shouldn't block descendant focusability. Instead, just prevent the number picker from being the first focused item in your view.

See this answer for details.

Based on the above answer:

    <!-- Dummy item to prevent Number Picker from receiving focus -->
    <LinearLayout        
        android:focusable="true" 
        android:focusableInTouchMode="true"
        android:layout_width="0px" 
        android:layout_height="0px"/>

    <!-- :nextFocusUp and :nextFocusLeft have been set to the id of this component 
         to prevent the dummy from receiving focus again -->
    <NumberPicker 
        android:id="@+id/number_picker"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:nextFocusUp="@id/number_picker" 
        android:nextFocusLeft="@id/number_picker"/>

I don't know why it works, but setting OnClickListener which does nothing prevented keyboard from showing (Lollipop)

numberPicker.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View view) {
  }
});

/**
 * set focus to top level window
 * disposes descendant focus
 * disposes softInput
 * @param context - activity context
 * @param enable - state of focus
 * */
public static void topLevelFocus(Context context, boolean enable){
    if(Activity.class.isAssignableFrom(context.getClass())){
        ViewGroup tlView = (ViewGroup) ((Activity) context).getWindow().getDecorView();
        if(tlView!=null){
            tlView.setFocusable(enable);
            tlView.setFocusableInTouchMode(enable);
            tlView.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);
            tlView.requestFocus();
        }
    }
}

* calling this:

• will not block descendant focusability (numberpicker will be editable)

• will hide soft input on create

• before (processing input) getValue() will allow to get proper walue

Working code Programatically :

mp.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS);

XML:

android:descendantFocusability="blocksDescendants"
