我的drawable会干扰我的按钮状态吗？

Question

现在，我有一个单选组作为父级，切换按钮作为子级。

所以是这样的：

布局.xml

<RadioGroup

                android:id="@+id/toggleGroup"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                android:background="@color/white"
                android:useDefaultMargins="true"

                android:layout_column="0"
                android:columnCount="11"
                android:rowCount="1"
                android:orientation="horizontal"
>

        <ToggleButton

                    android:id="@+id/number_zero"
                    android:layout_width="34sp"
                    android:layout_height="40sp"
                    android:layout_row="0"
                    android:layout_column="0"
                    android:textOn="@string/number_zero"
                    android:textOff="@string/number_zero"
                    android:layout_margin="5sp"

                    />
        <ToggleButton
                    android:id="@+id/number_one"
                    android:layout_width="34sp"
                    android:layout_height="40sp"
                    android:layout_row="0"
                    android:layout_column="1"
                    android:textOn="@string/number_one"
                    android:textOff="@string/number_one"
                    android:layout_margin="5sp"

                />
</RadioGroup>
</GridLayout> 

Adapter中的代码sn-p：

ToggleButton one;

one = (ToggleButton) view.findViewById(R.id.number_one);

 one.setOnClickListener(new View.OnClickListener()  {
                    public void onClick(View view) {
                        buttonValue = 1;

                        ToggleButton tb = (ToggleButton) view;

                        if(tb.isChecked()){

                            RadioGroup radioGroup = (RadioGroup) tb.getParent();

                            for(int i=0; i<(radioGroup).getChildCount(); ++i) {
                                View nextChild = (radioGroup).getChildAt(i);
                                if(nextChild instanceof ToggleButton && nextChild.getId()==tb.getId() ){


                                }else if (nextChild instanceof ToggleButton && nextChild.getId()!=tb.getId() ){

                                    ToggleButton tb2=(ToggleButton) nextChild;
                                    tb2.setChecked(false);
                                }
                            }

                        } else{
                            RadioGroup radioGroup = (RadioGroup) tb.getParent();

                            for(int i=0; i<(radioGroup).getChildCount(); ++i) {
                                View nextChild = (radioGroup).getChildAt(i);
                                if(nextChild instanceof ToggleButton && nextChild.getId()==tb.getId() ){
                                    ToggleButton tb2=(ToggleButton) nextChild;
                                    tb2.setChecked(false);
                                }else if (nextChild instanceof ToggleButton && nextChild.getId()!=tb.getId() ){
                                    ToggleButton tb2=(ToggleButton) nextChild;
                                    tb2.setChecked(false);

                                }
                            }
                        }
                    }
                });

以上内容针对我拥有的每个按钮重复。在此示例中为按钮 0 和 1。

可绘制：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item  android:state_pressed="true" android:state_checked="true" >
        <shape>
            <solid
                    android:color="@color/button_selected" />
            <stroke
                    android:width="1dp"
                    android:color="@color/button_selected"  />
            <padding
                    android:left="10dp"
                    android:top="10dp"
                    android:right="10dp"
                    android:bottom="10dp" />
        </shape>
    </item >
    <item>
        <shape android:state_checked="false">
            <solid
                    android:color="@color/number_button_grey" />
            <stroke
                    android:width="1dp"
                    android:color="@color/number_button_grey" />

            <padding
                    android:left="10dp"
                    android:top="10dp"
                    android:right="10dp"
                    android:bottom="10dp" />
        </shape>
    </item>
</selector>

我想要的行为：

我想在按钮之间切换，以便一次只按下一个按钮。例如，在这种情况下，如果我单击按钮零，则将按下零并且不按下按钮一。如果我单击按钮一，则按钮一被按下，而按钮零则不被按下。我希望按下状态为真。

出于某种原因，如果我删除了上面按钮的可绘制对象，我可以像单选按钮行为一样轻松切换，当我按下按钮时，它会保持按下状态。但是，当我应用我的可绘制对象时，按钮在按下时不会保持按下状态。只有当我单击按钮并用手指按住按钮时，状态才会改变。如果我移开手指，它会返回按下状态 = false。

我不确定为什么使用可绘制对象，这不是我想要的行为。

编辑：这是一个关于当我将切换按钮更改为单选按钮以及当我拥有切换按钮时的行为的视频。我在单选按钮之间切换，红色选择没有保持不变。我对切换按钮做同样的事情。 https://www.dropbox.com/s/9sinptgoucv1hvn/VIDEO0043.mp4?dl=0
