自定義列表視圖的自定義警報對話框

Question

我需要創建一個單一選擇的自定義警報對話框。 但物品有自己的布局：

[視圖（只是顏色）_______ TEXT_______RADIOBUTTON]

我為listview，自定義適配器創建了一個自定義布局，並且結果很好

但我不能做出單一選擇，沒有一個聽眾設置為listview ...：這是我的適配器：

public class AlertListAdapter extends BaseAdapter {

ArrayList<AlertChoiceItem> mData;
Context mContext;
LayoutInflater inflater;
public AlertListAdapter(ArrayList<AlertChoiceItem> data, Context context) {
    mData = data;
    mContext = context;
    inflater = LayoutInflater.from(context);
}
@Override
public int getCount() {
    return mData.size();
}

@Override
public Object getItem(int arg0) {
    return null;
}

@Override
public long getItemId(int arg0) {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if (convertView == null) {
        LayoutInflater mInflater = (LayoutInflater) mContext
                .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = mInflater.inflate(R.layout.item_alert_list, null);
    }
    TextView tvTitle = (TextView) convertView.findViewById(R.id.tvTitleAlertList);
    View v = (View) convertView.findViewById(R.id.vPriorAlertList);
    v.setBackgroundColor(GetColorByPriority.getColor(position, mContext));
    tvTitle.setText(mData.get(position).getTitle());
    RadioButton rb = (RadioButton) convertView.findViewById(R.id.rbRadioAlertList);


    return convertView;
}

}

在這里我創建警報：

AlertDialog.Builder dialog = new AlertDialog.Builder(getActivity());
                // dialog.setContentView(R.layout.alert_list_radio);
                dialog.setTitle("List Title");
                View customView = LayoutInflater.from(getActivity()).inflate(
                        R.layout.alert_list_radio, null, false);
                ListView listView = (ListView) customView.findViewById(R.id.lvAlertList);

                // ArrayAdapter<String> ad = new ArrayAdapter<String>(this,
                // R.layout.single_item_layout , R.id.singleItem, dummies);
                ArrayList<AlertChoiceItem> itemList = new ArrayList<AlertChoiceItem>();
                itemList.add(new AlertChoiceItem(false, "Critical", 5));
                itemList.add(new AlertChoiceItem(false, "High", 4));
                itemList.add(new AlertChoiceItem(false, "Medium", 3));
                itemList.add(new AlertChoiceItem(false, "Low", 2));
                itemList.add(new AlertChoiceItem(false, "Very low", 1));
                itemList.add(new AlertChoiceItem(false, "Off filter", 0));

                AlertListAdapter mAdapter = new AlertListAdapter(itemList, getActivity());
                listView.setAdapter(mAdapter);
                listView.setOnItemClickListener(mOnItemClick);
                listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
                dialog.setView(customView);
                dialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // TODO Auto-generated method stub

                    }
                });
                dialog.show();

如何添加單選？

UPD：AlertChoiceItem實現：

public class AlertChoiceItem {

private boolean isChecked;
private String title;
private int prior;
public AlertChoiceItem(boolean isChecked, String title, int prior) {
    super();
    this.isChecked = isChecked;
    this.title = title;
    this.prior = prior;
}
public boolean isChecked() {
    return isChecked;
}
public void setChecked(boolean isChecked) {
    this.isChecked = isChecked;
}
public String getTitle() {
    return title;
}
public void setTitle(String title) {
    this.title = title;
}
public int getPrior() {
    return prior;
}
public void setPrior(int prior) {
    this.prior = prior;
}

}

Answer 1

以這種方式解決問題：

1）使布局中的所有（！）視圖都不可聚焦。

2）將活動中的onClickItemListener設置為listview

3）每次點擊發送到適配器信號以刪除所有檢查，設置新（按位置）並重新繪制列表視圖。

Answer 2

在item_alert_list xml文件中設置

android:focusable = "false"
android:focusableInTouchMode="false"

為您的所有UI元素。

Answer 3

您可以嘗試將ItemClick偵聽器添加到列表視圖中

listView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View v, int position,
                long id) {
            // do whatever you want

        }
    });

Answer 4

檢查AlertChoiceItem的實現。 確保它實現了Checkable接口，並將其傳遞給您正在使用的底層RadioButton 。
