如何检测哪个按钮，并在该位置CustomList点击

问题描述

我正在使用中，我对每一个项目两个Button的自定义列表视图。以下是我的项目的XML。

I am using a custom listview in which i have two button for every item. following is the my item xml.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:weightSum="10">

            <Button
                android:id="@+id/btn_sound"
                android:layout_width="0dp"
                android:layout_height="fill_parent"
                android:layout_gravity="left"
                android:layout_marginLeft="3dp"
                android:layout_marginTop="3dp"
                android:layout_marginBottom="3dp"
                android:layout_marginRight="0dp"
                android:background="@drawable/btn_background"
                android:gravity="left|center_vertical"
                android:paddingLeft="10dp"
                android:text="Sound Name"
                android:textSize="20sp"
                android:textStyle="bold"
                 android:layout_weight="7" />

            <ImageButton
                android:id="@+id/ib_info"
                android:layout_width="0dp"
                android:layout_height="fill_parent"
                android:layout_gravity="right"
                android:gravity="left|center_vertical"
                android:layout_marginLeft="0dp"
                android:layout_marginTop="3dp"
                android:layout_marginBottom="3dp"
                android:layout_marginRight="3dp"
                android:layout_weight="3"
                android:src="@drawable/btn_info_source"
                android:background="@drawable/btn_info_background" />

</LinearLayout>

和以下是我使用的Addapter。

and Following is the Addapter I am using.

public class CustomListAdapter extends BaseAdapter implements OnClickListener {
    Context mContext;
    String[] mArrayList;

    public CustomListAdapter(Context context, String[] SoundNames) {
        this.mContext = context;
        this.mArrayList = SoundNames;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        Holder holder;
        if (convertView == null) {
            holder = new Holder();
            LayoutInflater inflater1 = (LayoutInflater) this.mContext
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            convertView = inflater1.inflate(R.layout.list_item, null);
            holder.btn_sound = (Button) convertView.findViewById(R.id.btn_sound);
            holder.ib_info = (ImageButton) convertView.findViewById(R.id.ib_info);
            convertView.setTag(holder);
        } else {
            holder = (Holder) convertView.getTag();
        }

        holder.btn_sound.setText(mArrayList[position]);
        //holder.btn_sound.setOnClickListener(this);
        return convertView;
    }

    private static class Holder {

        Button btn_sound;
        ImageButton ib_info;
    }

    @Override
    public int getCount() {
        return mArrayList.length;
    }

    @Override
    public Object getItem(int position) {
        return mArrayList[position];
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

}

和我设置列表视图在以下code。

and I am setting list view in following code.

public class SectionFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView;
        ListView mListView;
        Bundle args = getArguments();
        int currentView = args.getInt(Constants.ARG_SECTION_NUMBER) - 2;

        if (currentView == 0) {
            rootView = inflater.inflate(R.layout.deer, container, false);
            //mListView = (ListView) rootView.findViewById(R.id.listView_deer);
            CustomListAdapter mListAdapter = new CustomListAdapter(MainActivity.appContext, Constants.deer_Sound_Names);
            //mListView.setAdapter(mListAdapter);
            ((AdapterView<ListAdapter>) rootView.findViewById(R.id.listView_deer)).setAdapter(mListAdapter);
            ((AdapterView<ListAdapter>) rootView.findViewById(R.id.listView_deer)).setOnItemClickListener(mListner);


        } else if (currentView == 1) {
            rootView = inflater.inflate(R.layout.guide_layout, container, false);
            Toast.makeText(MainActivity.appContext, "Loading Guide...", Toast.LENGTH_LONG).show();
            WebView guideViewer = (WebView) rootView.findViewById(R.id.webView_guide);
            guideViewer.loadUrl("file:///android_asset/deer_html/guide.htm");

        } else {

            rootView = inflater.inflate(R.layout.activity_main, container,
                    false);
        }
        return rootView;
    }
    OnItemClickListener mListner = new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
            Log.d("HFI","Item Clicked: "+Constants.deer_Sound_Index[position]);
            switch (view.getId()) {
            case R.id.btn_sound:
                Log.d("HFI","Sound: "+Constants.deer_Sound_Index[position]);
                break;
            case R.id.ib_info:
                Log.d("HFI","Info: "+Constants.deer_Sound_Index[position]);
                break;
            default:
                break;
            }
        }
    };

}

问题：自定义列表视图不被registred与 setOnItemClickListener（mListner）;
Actualy我想检测哪个按钮，并在该位置已经被点击了 SectionFragment 类。

推荐答案

我在 getView 这对我的作品添加的onClick。
code：

I added onClick in the getView which works for me.Code:

public View getView(final int position, View convertView, ViewGroup parent) {
        Holder holder;
        if (convertView == null) {
            holder = new Holder();
            LayoutInflater inflater1 = (LayoutInflater) this.mContext
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater1.inflate(R.layout.list_item, null);
            holder.btn_sound = (Button) convertView.findViewById(R.id.btn_sound);
            holder.ib_info = (ImageButton) convertView.findViewById(R.id.ib_info);
            convertView.setTag(holder);
        } else {
            holder = (Holder) convertView.getTag();
        }

        holder.btn_sound.setText(mArrayList[position]);

        holder.btn_sound.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                //Sound Button Click
            }
        });
        holder.ib_info.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                //info Button Click
            }
        });
        return convertView;
    }
