リストビュー (レイアウトで膨らむ) と、BaseAdapter を拡張するカスタム アダプターがあります。リストビューの各行には、ラジオボタン、テキストビュー、およびイメージビューが含まれています。
私の問題は、すべてのラジオボタンを RadioGroup に追加できないことです。いつでも1つだけを選択できるようにラジオボタンを制御したい。
誰か助けてくれませんか?
リストビューの私のレイアウト:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/lv_activity_object_setup_final_objects"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
私のXMLは膨張していました:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RadioButton
android:id="@+id/rbn_activity_object_setup_final_list_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="22dp"
android:layout_marginTop="22dp"
android:text="" android:button="@drawable/radio_button"/>
<ImageView
android:id="@+id/img_activity_object_setup_final_list_layout_div_vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="22dp"
android:layout_marginTop="5dp"
android:layout_toRightOf="@id/rbn_activity_object_setup_final_list_layout"
android:src="@drawable/table_divider_vertical" />
<TextView
android:id="@+id/txv_activity_object_setup_final_list_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginTop="22dp"
android:layout_toRightOf="@id/img_activity_object_setup_final_list_layout_div_vertical"
android:text="Object"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ImageView
android:id="@+id/img_activity_object_setup_final_list_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginRight="16dp"
android:src="@drawable/object_icon_keys" />
カスタムアダプターの私のコード:
class ObjectAdapter extends BaseAdapter {
Context context;
List<ObjectType> objectTypeData;
LayoutInflater inflater;
public ObjectAdapter(Context context, List<ObjectType> objectTypeList) {
this.context = context;
inflater = LayoutInflater.from(context);
this.objectTypeData = objectTypeList;
}
@Override
public int getCount() {
return objectTypeData.size();
}
@Override
public Object getItem(int position) {
return objectTypeData.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewGroup vg;
if (convertView != null) {
vg = (ViewGroup) convertView;
} else {
vg = (ViewGroup) inflater.inflate(R.layout.activity_object_setup_final_list_layout, null);
}
ObjectType objectType = objectTypeData.get(position);
RadioButton radioButton = (RadioButton) vg.findViewById(R.id.rbn_activity_object_setup_final_list_layout);
radioButton.setButtonDrawable(getResources().getDrawable(R.drawable.radio_button));
if (objectType.getRadioButtonImage() == strDisabled) {
radioButton.setEnabled(false);
radioButton.setChecked(true);
}
else if (objectType.getRadioButtonImage() == strChecked) {
radioButton.setEnabled(true);
radioButton.setChecked(true);
}
else {
radioButton.setEnabled(true);
radioButton.setChecked(false);
}
TextView objectName = (TextView) vg.findViewById(R.id.txv_activity_object_setup_final_list_layout);
objectName.setText(objectType.getTitle());
ImageView objectImage = (ImageView) vg.findViewById(R.id.img_activity_object_setup_final_list_layout);
if (objectType.getObjectTypeImage() == getString(R.string.strKeys)) {
objectImage.setImageDrawable(getResources().getDrawable(R.drawable.object_icon_keys));
}
else if (objectType.getObjectTypeImage() == getString(R.string.strWallet)) {
objectImage.setImageDrawable(getResources().getDrawable(R.drawable.object_icon_wallet));
}
else if (objectType.getObjectTypeImage() == getString(R.string.strBag)) {
objectImage.setImageDrawable(getResources().getDrawable(R.drawable.object_icon_bag));
}
else if (objectType.getObjectTypeImage() == getString(R.string.strLaptop)) {
objectImage.setImageDrawable(getResources().getDrawable(R.drawable.object_icon_laptop));
}
else {
objectImage.setImageDrawable(getResources().getDrawable(R.drawable.object_icon_default));
}
return vg;
}
}
