RadioGroup с двумя столбцами, которые имеют десять RadioButton

у меня естьRadioGroup и я хочу выровнять кнопки рядом друг с другом в два столбца и пять строк, и я не могу этого добиться. Вещи, которые я пробовал:

RelativeLayout -> Outside RadioGroup -> Inside RadioGroup. All RadioButtons are selected, but I want only one to be selected. RadioGroup : orientation Span, stretchcolumns TableRow TableLayout

Пожалуйста, дайте мне знать, как создатьRadioGroup и имеют две колонки и многоRadioButtons в.

попробуйте метод вthis post.

Спасибо Кенди, у Luksprog есть рабочее решение. Еще раз спасибо

Ответы на вопрос(8)

linearlayout не может этого сделать, поэтому RadioGroup не может этого сделать.

Почему бы не реализовать это самостоятельно.

Используйте RelativeLayout для размещения дочернего представления. И запишите состояние детского просмотра. используйте setLevel для управления состояниями.

Удачи тебе!.

Спасибо Чанвэй Яо.

используя LinearLayout, каждый из которых имеет 5 RadioButton и используя свойство layout_weight, разместите их рядом на экране. Затем создайте слушателя для этих радиогрупп, как показано ниже:

rg1 = (RadioGroup) findViewById(R.id.radiogroup1);
rg2 = (RadioGroup) findViewById(R.id.radiogroup2);
rg1.clearCheck();//this is so we can start fresh, with no selection on both RadioGroups
rg2.clearCheck();
rg1.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // TODO Auto-generated method stub
            if (checkedId != -1) {
                fun2();
            }
        }
    });

    rg2.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // TODO Auto-generated method stub
            if (checkedId != -1) {
                fun1();
            }
        }
    });

И fun1 () & amp; fun2 () будет определен как показано ниже:

public void fun1() {
     rg1.setOnCheckedChangeListener(null);
     rg1.clearCheck();
     rg1.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            fun2();
            Log.v("Inside fun1","fun2");
        }
    });
}

public void fun2() {
     rg2.setOnCheckedChangeListener(null);
     rg2.clearCheck();
     rg2.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // TODO Auto-generated method stub
            fun1();
            Log.v("Inside fun2","fun1");

        }
    });
}

Не работает! rg1 слушатель щелчка не срабатывает при смене переключателя в этой группе. Сначала нужно нажать кнопку-переключатель в rg2, прежде чем ударить хотя бы одного слушателя.

что на ваш вопрос уже дан ответ, но здесь есть другое решение. С помощью этого кода вы можете обернуть ваши радиокнопки в любой нужный вам макет (на самом деле вам вообще не нужна радиогруппа). Также я бы предложил использовать линейные макеты для создания нужных вам столбцов / строк.

Мой код основан на @infografnet и @lostdev (также спасибо, @ Neromancer за предложение «Составная кнопка»!)

public class AdvRadioGroup {
    public interface OnButtonCheckedListener {
        void onButtonChecked(CompoundButton button);
    }

    private final List<CompoundButton> buttons;
    private final View.OnClickListener onClick = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            setChecked((CompoundButton) v);
        }
    };

    private OnButtonCheckedListener listener;
    private CompoundButton lastChecked;


    public AdvRadioGroup(View view) {
        buttons = new ArrayList<>();
        parseView(view);
    }

    private void parseView(final View view) {
        if(view instanceof CompoundButton) {
            buttons.add((CompoundButton) view);
            view.setOnClickListener(onClick);
        } else if(view instanceof ViewGroup) {
            final ViewGroup group = (ViewGroup) view;
            for (int i = 0; i < group.getChildCount();i++) {
                parseView(group.getChildAt(i));
            }
        }
    }

    public List<CompoundButton> getButtons() { return buttons; }

    public CompoundButton getLastChecked() { return lastChecked; }

    public void setChecked(int index) { setChecked(buttons.get(index)); }

    public void setChecked(CompoundButton button) {
        if(button == lastChecked) return;

        for (CompoundButton btn : buttons) {
            btn.setChecked(false);
        }

        button.setChecked(true);

        lastChecked = button;

        if(listener != null) {
            listener.onButtonChecked(button);
        }
    }

    public void setOnButtonCheckedListener(OnButtonCheckedListener listener) { this.listener = listener; }
}

Использование (с включенным слушателем):

AdvRadioGroup group = new AdvRadioGroup(findViewById(R.id.YOUR_VIEW));
group.setOnButtonCheckedListener(new AdvRadioGroup.OnButtonCheckedList,ener() {
    @Override
    public void onButtonChecked(CompoundButton button) {
        // do fun stuff here!
    }
});

Бонус: Вы можете получить последнюю проверенную кнопку, список всех кнопок, и вы можете проверить любую кнопку по индексу с этим!

но сложнее, чем требуется для более простых случаев. Если вы просто хотите, чтобы несколько радиогрупп действовали как одна и могли обрабатывать все решения, принимаемые в момент нажатия, тогда вы можете сделать это:

В макете XML добавьте тот же обработчик кликов вall из RadioButtons, которые вы хотите объединить:

android:onClick="handleCombinedClick"

Затем, чтобы ваш обработчик кликов выглядел примерно так:

public void handleCombinedClick(View view) {
    // Clear any checks from both groups:
    rg1.clearCheck();
    rg2.clearCheck();

    // Manually set the check in the newly clicked radio button:
    ((RadioButton) view).setChecked(true);

    // Perform any action desired for the new selection:
    switch (view.getId()) {
        case R.id.radio_button_1:
            // do something
            break;

        case R.id.radio_button_2:
            // do something
            break;

        ...
    }
}

Это дает дополнительное преимущество, так как все ваши выборы обрабатываются в одном месте. И если вы хотите расширить это до 3 или более радиогрупп, то вам просто нужно добавить дополнительнуюrgX.clearCheck(); строка для каждой добавленной группы.

Решение Вопроса

RadioGroup чтобы он выглядел так, будто у тебя есть только один. Например, у вас естьrg1 а такжеrg2(RadioGroups с ориентацией, установленной наvertical(две колонки)). Чтобы настроить этиRadioGroups:

rg1 = (RadioGroup) findViewById(R.id.radioGroup1);
rg2 = (RadioGroup) findViewById(R.id.radioGroup2);
rg1.clearCheck(); // this is so we can start fresh, with no selection on both RadioGroups
rg2.clearCheck();
rg1.setOnCheckedChangeListener(listener1);
rg2.setOnCheckedChangeListener(listener2);

Чтобы выбрать только одинRadioButton в техRadioGroups слушатели выше будут:

private OnCheckedChangeListener listener1 = new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            if (checkedId != -1) {
                rg2.setOnCheckedChangeListener(null); // remove the listener before clearing so we don't throw that stackoverflow exception(like Vladimir Volodin pointed out)
                rg2.clearCheck(); // clear the second RadioGroup!
                rg2.setOnCheckedChangeListener(listener2); //reset the listener
                Log.e("XXX2", "do the work");
            }
        }
    };

    private OnCheckedChangeListener listener2 = new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            if (checkedId != -1) {
                rg1.setOnCheckedChangeListener(null);
                rg1.clearCheck();
                rg1.setOnCheckedChangeListener(listener1);
                Log.e("XXX2", "do the work");
            }
        }
    };

Чтобы получить проверенныйRadioButton отRadioGroups Вы могли бы сделать:

int chkId1 = rg1.getCheckedRadioButtonId();
int chkId2 = rg2.getCheckedRadioButtonId();
int realCheck = chkId1 == -1 ? chkId2 : chkId1;

Если вы используетеcheck() методRadioGroup Вы должны помнить, чтобы позвонитьclearCheck() с другойRadiogroup.

Должно работать, я исправил это сам, используя только логический флаг вместо отключения слушателя.

Смешно, что мы должны пройти через все это только для того, чтобы мы могли иметь более 2 столбцов радиокнопок.

Нет, мои настройки так же просты, как и ваши. Проблема в том, что clearCheck () всегда приводит к вызову onCheckedChangeListener ().

dioButtonGroup. Я динамически добавил переключатели в TableRows. Вот класс:

public class RadioGroupColumns extends TableLayout implements OnClickListener {

private static final String TAG = "RadioGroupColumns";
private RadioButton activeRadioButton;
private int mCheckedId = -1;
// tracks children radio buttons checked state
private CompoundButton.OnCheckedChangeListener mChildOnCheckedChangeListener;
// when true, mOnCheckedChangeListener discards events
private boolean mProtectFromCheckedChange = false;
private OnCheckedChangeListener mOnCheckedChangeListener;
private PassThroughHierarchyChangeListener mPassThroughListener;

public RadioGroupColumns(Context context) {
    super(context);
    setOrientation(VERTICAL);
    init();
}

public RadioGroupColumns(Context context, AttributeSet attrs) {
            super(context, attrs);
            Resources res = Resources.getSystem();
            int value = 0;
            // retrieve selected radio button as requested by the use,r in the
            // XML layout file

            TypedArray attributes = null;
            try {
                attributes = context.obtainStyledAttributes(attrs, getAttributes(context), R.attr.radioButtonStyle, 0);
                value = attributes.getResourceId(getAttribute(context), View.NO_ID);
            } catch (IllegalAccessException e) {
                // TODO Auto-generated catch block
                Log.d("Exception RadioGroupColumns Construct",e.toString());
                e.printStackTrace();
            }
            catch (ClassNotFoundException e) { 
                Log.d("Exception RadioGroupColumns Construct",e.toString());
                e.printStackTrace();
            }  


            if (value != View.NO_ID) {
                mCheckedId = value;
            }

            //hardcode it to vertical
            //final int index = attributes.getInt(com.android.internal.R.styleable.RadioGroup_orientation, VERTICAL);
            //setOrientation(index);

            attributes.recycle();

            setOrientation(VERTICAL);
            init();
}

@Override
public void onClick(View v) {
    if (v instanceof TableRow) {
        TableRow row = (TableRow)v;
        for (int j=0;j<row.getChildCount();j++) { 
            if (RadioButton.class.isAssignableFrom(row.getChildAt(j).getClass())) {

                ((RadioButton) row.getChildAt(j)).setChecked(true);
                activeRadioButton = (RadioButton) row.getChildAt(j);
            }
        }
    }
    else { 
        final RadioButton rb = (RadioButton) v;

        if (activeRadioButton != null) {
            activeRadioButton.setChecked(false);
        }
        rb.setChecked(true);
        activeRadioButton = rb;

Она не будет работать. Если я проверяю любую радиопереключатель, то другая радиопереключатель не отключается автоматически.

Я обновил код, так как я разместил его здесь. Обновленный находится по этой ссылке: https://github.com/Gavras/MultiLineRadioGroup/blob/master/app/src/main/java/com/whygraphics/multilineradiogroup/MultiLineRadioGroup.java

Что-то очень маленькое, что я сделал, когда мне нужно было многоканальное радио

Это пользовательское представление, которое расширяет RadioGroup.

у вас есть возможность выбрать максимальное количество кнопок в строке. Он основан на TableLayout, поэтому он также выравнивает кнопки. Все задокументировано.

/**
 * Layout that arranges radio buttons in multiple lines.
 * Only one radio button can be checked at the same time.
 * <p>
 * XML Attributes:
 * <p>
 * max_in_row:
 * A non-negative number that represents the maximum radio buttons in a row,
 * 0 for all in one line.
 * <p>
 * radio_buttons:
 * String-array resource reference that represents the texts of the desired radio buttons.
 * <p>
 * default_button:
 * String that represents the text or the index of the radio button to be checked by default.
 * The string should be in the following format:
 * for text: "text:[text-of-button]" where text-of-button is the text of the button to check.
 * for index: "index:[index-of-button]" where index-of-button is the index of the button to check.
 * when the prefix omitted, "text:" inserted implicitly.
