现在问题是我想点击单选按钮并获取textconfigurationid并传递给变量

请帮帮我..

由于

Answer 1

我无法正确理解您的问题，但我想您希望获得RadioButton和TextView（textconfigurationid）的值以存储在变量中。

您可以在BaseAdapter中的getView方法中处理点击事件。像这样：

public View getView(final int position, View convertView, ViewGroup parent) {
     //***
              Your code here..
                                 ***//      
    itemView.setBackgroundColor(color);

    //You can get value of radio button and textview like this.
    Boolean radioValue = shipping_title.isChecked();
    int configId = configuration_id.getText();

    return itemView;
}

Answer 2

尝试使用radioButton.isChecked（），它会告诉您是否选中了单选按钮。此外，您可以使用

radioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

        }

    });

Answer 3

我用这段代码解决了我的问题..

mconfiguration_id = configuration_id.getText().toString();
        shipping_title.setTag(mconfiguration_id);
        shipping_title.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                if (position != mSelectedPosition && mSelectedRB != null) {
                    mSelectedRB.setChecked(false);
                }

                mSelectedPosition = position;
                mSelectedRB = (RadioButton) v;

                String mconfiguration_id;
                mconfiguration_id = v.getTag().toString();
                Toast.makeText(context, mconfiguration_id, Toast.LENGTH_SHORT).show();
            }

        });

        if(mSelectedPosition != position){
            shipping_title.setChecked(false);
        }else{
            shipping_title.setChecked(true);
            if(mSelectedRB != null && shipping_title != mSelectedRB){
                mSelectedRB = shipping_title;
            }
        }
