RadioGroup中延伸RelativeLayout的？ [英] RadioGroup extending RelativeLayout?

问题描述

我试图让一个单选按钮网格我的应用程序，我所学到的是，这是不可能使用普通的 RadioGroup中，因为它扩展的LinearLayout和如果您尝试安排单选按钮使用RelativeLayout的在 RadioGroup中的 RadioGroup中不看按钮在 RelativeLayout的。

因此​​，为了解决这个问题我想打一个自定义的RadioGroup中扩展RelativeLayout的，而不是LinearLayout中。

我如何做到这一点？

更新：我没有你所说的话，但我有这些错误，我不知道如何在类文件修复：

解决方案

您需要从<一个的 RadioGroup中的源$ C ​​$ C href="http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/java/android/widget/RadioGroup.java;h=393346a314f7b1ad20c617c494904f599391c081;hb=HEAD"相对=nofollow>此处，与 RelativeLayout的的LinearLayout 所有条目>。

将此code一些XML文件在您的项目（通常它的名字是attr​​s.xml）：

 ＆LT;资源＆GT;
    ＆LT;申报，设置样式名称=RadioGroup中＆GT;
        ＆LT; attr指示名=机器人：checkedButton/＆GT;
    ＆LT; /申报，设置样式＆GT;
＆LT; /资源＆GT;
 

替换 RadioGroup中的构造与这些：

 公共RadioGroup中（上下文的背景下）{
    超（上下文）;
    如果（！isInEditMode（））{
        在里面（）;
    }
}

公共RadioGroup中（上下文的背景下，ATTRS的AttributeSet）{
    超（背景下，ATTRS）;
    如果（！isInEditMode（））{
        TypedArray属性= context.obtainStyledAttributes（
                的attrs，R.styleable.RadioGroup，0，
                android.R.style.Widget_CompoundButton_RadioButton）;

        int值= attributes.getResourceId（R.styleable.RadioGroup_checkedButton，
            View.NO_ID）;
        如果（值！= View.NO_ID）{
            mCheckedId =价值;
        }

        attributes.recycle（）;
        在里面（）;
    }
}
 

拆下的LayoutParams 内部类下面的构造：

 公开的LayoutParams（INT W，INT小时，浮initWeight）{
    超（W，H，initWeight）;
}
 

替换 setOnCheckedChangeWidgetListener所有出现的（）与 setOnCheckedChangeListener（）方法方法调用。 重要：在这种情况下，将无法从使用该部件一个code使用这种方法

有没有试过，但希望这会工作。

I'm trying to make a grid of radio buttons for my app, what I have learned is that this isn't possible using regular RadioGroup because it extends LinearLayout and if you try to arrange the RadioButtons using RelativeLayout INSIDE the RadioGroup the RadioGroup doesn't see the Buttons inside the RelativeLayout.

So in order to fix this I want to make a custom RadioGroup that extends RelativeLayout instead of LinearLayout.

How do I do this?

UPDATE: I did what you said but I have these errors I don't know how to fix in the class file:

解决方案

You need to get the RadioGroup's source code from here, replace all entries of LinearLayout with RelativeLayout.

Add this code to some xml file in your project (usually its name is attrs.xml):

<resources>
    <declare-styleable name="RadioGroup">
        <attr name="android:checkedButton" />
    </declare-styleable>
</resources>

Replace RadioGroup's constructors with these:

public RadioGroup(Context context) {
    super(context);
    if (!isInEditMode()) {
        init();
    }
}

public RadioGroup(Context context, AttributeSet attrs) {
    super(context, attrs);
    if (!isInEditMode()) {
        TypedArray attributes = context.obtainStyledAttributes(
                attrs, R.styleable.RadioGroup, 0,
                android.R.style.Widget_CompoundButton_RadioButton);

        int value = attributes.getResourceId(R.styleable.RadioGroup_checkedButton,
            View.NO_ID);
        if (value != View.NO_ID) {
            mCheckedId = value;
        }

        attributes.recycle();
        init();
    }
}

Remove the following constructor from the LayoutParams inner class:

public LayoutParams(int w, int h, float initWeight) {
    super(w, h, initWeight);
}

Replace all occurrences of setOnCheckedChangeWidgetListener() method calls with the setOnCheckedChangeListener() method. IMPORTANT: In this case it won't be possible to use this method from a code that uses this widget.

Haven't tried this but hope this will work.
