如何获取在 gridview 中单击的 android 切换按钮的位置?
如果我使用以下示例代码,我不会收到该职位的 Toast 消息。
public class HelloGridView extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ToggleButtonAdapter(this));
gridview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View v, int position,
long id) {
Toast.makeText(HelloGridView.this, "" + position, Toast.LENGTH_SHORT).show();
}
});
}
}
和切换适配器:
public class ToggleButtonAdapter extends BaseAdapter {
private Context mContext;
public ToggleButtonAdapter(Context c) {
mContext = c;
}
@Override
public int getCount() {
return 5;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view;
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) { // reuse it if it already exists
view = (View) inflater.inflate(R.layout.items, null);
} else {
view = (View) convertView;
}
ToggleButton toggleButton = (ToggleButton) view.findViewById(R.id.toggleButton1);
TextView textView = (TextView) view.findViewById(R.id.textView1);
textView.setText("Toggle Button " + position);
/*toggleButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
ToggleButton t = (ToggleButton) v.findViewById(R.id.toggleButton1);
Toast.makeText(mContext, Boolean.toString(t.isChecked()), Toast.LENGTH_SHORT).show();
}
});*/
return view;
}
}
取消注释切换侦听器以使用该部分并告诉我如何获得位置。有没有办法在构建网格视图时将一些数据注入到切换按钮中,以便我以后参考?我找不到阅读 ToggleButton javadoc 的方法。
非常感谢!

哎呀!这里是布局:
主要的.xml
