Question

请教一个关于Android开发ListView的问题

我的LV每条item都有一个button,我该怎样通过点击item上的button获得当前item的position呢?不是直接点击item,如果直接点击item可以通过setOnItemClickListener去拿.
有懂的麻烦指导一下,谢谢!

Answer 1

在ListView的Item中有一个Switch控件，当Item过多屏幕装不下时，如果上下滑动使未显示的Item显示，这时开始和结尾的几个Item中的Switch控件会自动改变状态，并响应状态改变的事件。如果Item越多，会自动改变的Switch控件就越多。求解决方法，谢谢！
private class MAdapter extends CursorAdapter
{
private Context context;
private LayoutInflater mInflater;

public MAdapter(Context context, Cursor c)
{
super(context, c, true);

this.context = context;
mInflater = LayoutInflater.from(context);
}

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent)
{
View v = mInflater.inflate(R.layout.main_task_list_item, null);
return v;
}

@Override
public void bindView(View view, Context context, Cursor cursor)
{
final MZTask task = new MZTask(cursor);

// ic
ImageView ic = (ImageView) view
.findViewById(R.id.main_list_action_ic);
ic.setImageResource(task.getIcId());

// action name
TextView actionName = (TextView) view
.findViewById(R.id.main_list_action_name);
actionName.setText(task.getActionName(context));

// time
TextView time = (TextView) view
.findViewById(R.id.main_list_task_time);
time.setText(task.getTimeString());

// repeat
TextView repeat = (TextView) view
.findViewById(R.id.main_list_task_repeat);
repeat.setText(task.getDayStringOfWeek(context));

// switch view
final Switch stch = (Switch) view
.findViewById(R.id.main_list_task_switch);
stch.setOnCheckedChangeListener(getCheckedChangeListener(task));
stch.setChecked(task.state());

// list more
RelativeLayout icLayout = (RelativeLayout) view
.findViewById(R.id.main_list_more);
icLayout.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
popUpMenu(task);
}
});

// ..
RelativeLayout itemLayout = (RelativeLayout) view
.findViewById(R.id.main_list_layout_switch);
itemLayout.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
stch.setChecked(!stch.isChecked());
}
});

}

public OnCheckedChangeListener getCheckedChangeListener(
final MZTask task)
{
return new OnCheckedChangeListener()
{
public void onCheckedChanged(CompoundButton button,
boolean change)
{
if (change)
task.startTask(context, dbAdapter);
else
task.cancelTask(context, dbAdapter);
}
};
}

}
