如何触发单选按钮以检查是否按了线性布局 [英] How to trigger radioButton to checked if I pressed on Linear layout

问题描述

如果我在1线性布局内的其他位置(而不是单选按钮)上但在图像，文本视图等上按下，如何使单选按钮被选中.

How can I make the radio button get selected if I pressed on other place ( not the radio button ) but on image, text view and etc inside 1 Linear layout.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <LinearLayout
        android:id="@+id/layout_1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <ImageView
            android:id="@+id/card_balance"
            android:layout_width="150dp"
            android:layout_height="150dp"
            android:layout_gravity="center_vertical"
            android:paddingLeft="20dp" />

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:paddingLeft="10dp"
            android:textColor="@color/dc_white" />

        <RadioGroup
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:gravity="right"
            android:paddingRight="20dp">

            <RadioButton
                android:id="@+id/radio_button_payment"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />
        </RadioGroup>

    </LinearLayout>
    
    
</RelativeLayout>

这是adapater:PaymentAdapter.java

And here is the adapater: PaymentAdapter.java

     @Override
        public View getView(final int position, View convertView, ViewGroup parent) {
            LayoutInflater inflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            View allView = inflater.inflate(R.layout.item_choose_payment, parent, false);
            TextView txt1 = (TextView) allView.findViewById(R.id.textView1);
            ImageView imageView = (ImageView) allView.findViewById(R.id.card_balance);
            final RadioButton r = (RadioButton) allView.findViewById(R.id.radio_button_payment);
            LinearLayout layout_card = (LinearLayout) allView.findViewById(R.id.layout_1);

            r.setChecked(position == selectedPosition);
            r.setTag(position);
            r.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    selectedPosition = (Integer) view.getTag();
                    notifyDataSetChanged();
                }
            });
}

现在的条件是我只能在单选按钮上按下.

Right now the condition is I can pressed only at radio button.

我已经尝试过将onClickListener添加到线性布局，是的，我可以按线性布局，但是单选按钮不仅选择了1，还选择了全部.

I've already tried to add onClickListener to linear layout, and yes I can pressed on the linear layout however the Radio button not select only 1 but all selected.

此代码用于linearLayout onClick

this code for linearLayout onClick

 layout_card.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                r.setChecked(position == selectedPosition);
                r.setTag(position);
                if (r.isChecked()) {
                    r.setChecked(true);
                    r.setSelected(true);
                } else if (!r.isChecked()) {
                    r.setChecked(false);
                    r.setSelected(false);
                }
            }
        });

对不起，我的解释很不好，对于我的帮助，我深表感谢. 谢谢

Sorry for my bad explanation, any help is very grateful for me. Thank you

推荐答案

在您的 getView(...)内，写

layout_card.setTag(position);

并将点击侦听器更改为

layout_card.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            selectedPosition = Integer.parseInt(v.getTag().toString());
            notifyDataSetChange();
        }
    });

如果不需要，请删除下面的代码

remove below code, if not needed

        r.setTag(position);
        r.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                selectedPosition = (Integer) view.getTag();
                notifyDataSetChanged();
            }
        });
