问题描述

我试图用作为出现在标题的网站上的第一个答案提供的code。我不能让它工作，尽管我试图修改它。问题是，当我检查比第一个单选按钮以外的单选按钮，它们都保持选中。

问题是：？办时，addView方法被调用

此外，这里是我的版本的code，我希望有人能告诉我我的错误：

解决方案

只需修改setChildrenOnClickListener：

 私人无效setChildrenOnClickListener（TR的TableRow）{
    最终诠释C = tr.getChildCount（）;
    的for（int i = 0;我c为C;我++）{
        最后的视图V = tr.getChildAt（I）
        如果（V的instanceof单选）{
            v.setOnClickListener（本）;
            如果（（（单选按钮）ⅴ）.isChecked（））
                activeRa​​dioButton =（单选）V;
        }
    }}
 

I tried to use the code provided as the first answer on the website that appears in the title. I can't make it work, although I tried to modify it. The problem is that when I check a radio button other than the first radio button, they both stay checked.

Question is: when do the addView methods get called?

Also, here is my version of the code, I hope somebody can show me my mistakes:

public class ToggleButtonGroupTableLayout extends TableLayout  implements     OnClickListener {

private static final String TAG = "ToggleButtonGroupTableLayout";
private ToggleButtonGroupTableLayout radGroup;
private RadioButton activeRadioButton;

/** 
 * @param context
 */
public ToggleButtonGroupTableLayout(Context context) {
    super(context);
    // TODO Auto-generated constructor stub
}

/**
 * @param context
 * @param attrs
 */
public ToggleButtonGroupTableLayout(Context context, AttributeSet attrs) {
    super(context, attrs);
    // TODO Auto-generated constructor stub
}

@Override
public void onClick(View v) {
    final RadioButton rb = (RadioButton) v;
    radGroup = (ToggleButtonGroupTableLayout) findViewById(R.id.radGroup1);
    int activeRadioButtonId = radGroup.getCheckedRadioButtonId(v);
    Log.i(TAG,"FIRST " + activeRadioButtonId);
//       if (activeRadioButtonId != -1 && activeRadioButton != null ) {
//           activeRadioButton.setChecked(false);
//       }
    rb.setChecked(true);
    //activeRadioButton = rb;
    if (activeRadioButtonId != -1 && activeRadioButton != null ) {
        activeRadioButton = (RadioButton) findViewById(activeRadioButtonId);
        activeRadioButton.setChecked(false);
    }
    else
        Log.i(TAG,"" + activeRadioButton + "  " + activeRadioButtonId);
}

/* (non-Javadoc)
 * @see android.widget.TableLayout#addView(android.view.View, int,   android.view.ViewGroup.LayoutParams)
 */
@Override
public void addView(View child, int index,
        android.view.ViewGroup.LayoutParams params) {
    super.addView(child, index, params);
    setChildrenOnClickListener((TableLayout)child);
}


/* (non-Javadoc)
 * @see android.widget.TableLayout#addView(android.view.View, android.view.ViewGroup.LayoutParams)
 */
@Override
public void addView(View child, android.view.ViewGroup.LayoutParams params) {
    super.addView(child, params);
    setChildrenOnClickListener((TableLayout)child);
}


private void setChildrenOnClickListener(TableLayout tl) {
    final int c = tl.getChildCount();
    for (int i=0; i < c; i++) {
        final View v = tl.getChildAt(i);
        if ( v instanceof TableRow ) {
            final int c1 = ((TableRow) v).getChildCount();
            for (int j = 0; j < c1; j++) {
               View v1 = ((TableRow) v).getChildAt(j);
               if (v1 instanceof RadioButton)
                   v1.setOnClickListener(this);
            }
        }
    }
}

public int getCheckedRadioButtonId(View v) {
    if ( activeRadioButton != null ) {
        return activeRadioButton.getId();
    }

    return -1;
}

解决方案

Just modify setChildrenOnClickListener:

 private void setChildrenOnClickListener(TableRow tr) {
    final int c = tr.getChildCount();
    for (int i=0; i < c; i++) {
        final View v = tr.getChildAt(i);
        if (v instanceof RadioButton) {
            v.setOnClickListener(this);
            if (((RadioButton) v).isChecked())
                activeRadioButton = (RadioButton) v;
        }
    }

}
