获得按钮点击列表视图中的每一行 [英] Get click from button on every row in listview

问题描述

我产生了的ListView 所看到如下

我没有足够的代表处发布的图片，你将不得不破译我的网址：图片

I don't have enough rep to post images, you'll have to decipher my URL: image

的蓝色的上述图像中的行使用的HashMap 填充：

The blue rows in the above image are populated using HashMap:

private void showListView(JSONArray rows, JSONArray totals){

final ListView list = (ListView) findViewById(R.id.historylist);
ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map;
String[] titles = new String[]{"recordID","date","description","num1","num2"};
SimpleAdapter mSchedule = null;

try{

    for(int i=0;i<rows.length();i++){
        map = new HashMap<String, String>();
        for(int n=0;n<allRows.getJSONArray(i).length();n++){
            map.put(titles[n], allRows.getJSONArray(i).getString(n));
        }
        mylist.add(map);
    }

    mSchedule = new SimpleAdapter(
        History.this,
        mylist,
        R.layout.history_row,
        titles,
        new int[] {R.id.textView0, R.id.textView1, R.id.textView2, R.id.textView3, R.id.textView4}
    );

    list.setAdapter(mSchedule);

}catch(Exception e){
    Log.e("Creating ListView", e.toString());
}

}

<LinearLayout >

<LinearLayout >
    <LinearLayout >
        <TextView (recordID) />
        <TextView (date) />
        <TextView (num1) />
        <TextView (num2) />
    </LinearLayout>
    <TextView (description) />
</LinearLayout>

<LinearLayout (When this one is clicked) >
    <ImageView />
</LinearLayout>

在上面的图像中的绿色按钮后，我还想得到蓝色的行的信息。

When the green button in the above image is clicked, Id like to get the blue row information.

（日期，描述，NUM1，NUM2）

(date, description, num1, num2)

另外，如果你想有一个更好的方式来填充的ListView ，请让我知道。

Also, if you think there's a better way to populate the ListView, please let me know.

推荐答案

您将需要通过扩展的 BaseAdapter 。在 getView 方法，你需要绑定到按钮的Click事件。我建议有 OnClickListener 的一个实例，使用<一个href=\"http://developer.android.com/reference/android/widget/AdapterView.html#getPositionForView%28android.view.View%29\"相对=nofollow> 适配器视图＃getPositionForView 。一旦你有用于保持被点击，那么你可以得到你的数据的按钮视图的位置。无论是通过 适配器＃的getItem 或直接从您的数据源。

You will need to implement your own custom adapter by extending BaseAdapter. In the getView method you'll need to bind to that Button's click event. I suggest having one instance of OnClickListener and using AdapterView#getPositionForView. Once you have the position for the view holding the button that was clicked then you can get to your data. Either via Adapter#getItem or directly from your data source.
