setOnItemClickListener在创建导航抽屉时不在ListView上工作 [英] setOnItemClickListener not working on ListView while creating Navigation Drawer

问题描述

我正在尝试添加一个肯定有listview的导航抽屉。实现`setOnItemClickListener`时，我什么都没得到。请告诉我我做错了什么。



//加载幻灯片菜单项

navMenuTitles = getResources（）。getStringArray（R.array .nav_drawer_items）;

//来自资源的导航抽屉图标

navMenuIcons = getResources（）

.obtainTypedArray（R.array.nav_drawer_icons）;

mDrawerLayout =（DrawerLayout）findViewById（R.id.drawer_layout）;

mDrawerList =（ListView）findViewById（R.id.left_drawer）;



navDrawerItems = new ArrayList< navdraweritem>（）;

navDrawerItems

.add（new NavDrawerItem（Profile，R.drawable） .ic_launcher））;

navDrawerItems.add（new NavDrawerItem（Achievement，

R.drawable.ic_launcher））;



//回收键入的数组

navMenuIcons.recycle（）;

mDrawerList.setOnItemClickListener（new SlideMenuClickListener（））;


//设置导航抽屉列表适配器

adapter = new NavDraweListAdapter（getApplicationContext（），

navDrawerItems）;

mDrawerList.setAdapter（adapter）;

mDrawerLayout.setDrawerListener（mDrawerToggle）;



if（savedInstanceState == null）{

//第一次导航项目的首次显示视图

displayView（0）;

}



}



这是SlideMenuItemClickListener类



私有类SlideMenuClickListener实现

ListView.OnItemClickListener {

@Override

public void onItemClick（AdapterView long id）{

//显示所选导航抽屉的视图item

// displayView（position）;

Toast.makeText（getApplicationContext（），hari ram，

Toast.LENGTH_LONG）。 show（）;

}

} < br $>


及以下是NavDrawerListAdapter类，它使用BaseAdapter类的方法



公共类NavDraweListAdapter扩展BaseAdapter {$ / $


私有上下文上下文;

private ArrayList< navdraweritem> navDrawerItems;



public NavDraweListAdapter（Context context，ArrayList< navdraweritem> navDrawerItems）{

this.context = context;

this.navDrawerItems = navDrawerItems;

}



@Override

public int getCount（）{

返回navDrawerItems.size（）;

}



@Override

public Object getItem（int position）{

返回navDrawerItems.get（position）;

}



@覆盖

public long getItemId（int position）{

返回位置;

}



@Override

public View getView（int position，View convertView，ViewGroup parent）{

if（convertView == null）{

LayoutInflater mInflater =（LayoutInflater）

context.getSystemService（Activity.LAYOUT_INFLATER_SERVICE）;

convertView = mInflater.inflate（R.layout.drawer_list_item，null）;

}



ImageView imgIcon =（ImageView）convertView.findViewById（R.id.icon）;

TextView txtTitle =（ TextView）convertView.findViewById（R.id.title）;

TextView txtCount =（TextView）convertView.findViewById（R.id.counter）;



imgIcon.setImageResource（navDrawerItems.get（position）.getIcon（））;

txtTitle.setText（navDrawerItems.get（position）.getTitle（））;





//显示计数

//检查它是否设置可见

if（navDrawerItems.get（position）.getCounterVisibility（））{

txtCount .setText（navDrawerItems.get（position）.getCount（））;

} else {

//隐藏计数器视图

txtCount。 setVisibility（View.GONE）;

}



返回convertView;

}



}

I'm trying to add a Navigation Drawer which definitely has a listview. When implementing the `setOnItemClickListener` I get nothing. Please tell me what am I doing wrong.

// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);

navDrawerItems = new ArrayList<navdraweritem>();
navDrawerItems
.add(new NavDrawerItem("Profile", R.drawable.ic_launcher));
navDrawerItems.add(new NavDrawerItem("Achievement",
R.drawable.ic_launcher));

// Recycle the typed array
navMenuIcons.recycle();
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());

// setting the nav drawer list adapter
adapter = new NavDraweListAdapter(getApplicationContext(),
navDrawerItems);
mDrawerList.setAdapter(adapter);
mDrawerLayout.setDrawerListener(mDrawerToggle);

if (savedInstanceState == null) {
// on first time display view for first nav item
displayView(0);
}

}

This is SlideMenuItemClickListener class

private class SlideMenuClickListener implements
ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView long id) {
// display view for selected nav drawer item
// displayView(position);
Toast.makeText(getApplicationContext(), "hari ram" ,
Toast.LENGTH_LONG).show();
}
}

and below is the NavDrawerListAdapter class, which uses the methods of BaseAdapter class

public class NavDraweListAdapter extends BaseAdapter{

private Context context;
private ArrayList<navdraweritem> navDrawerItems;

public NavDraweListAdapter(Context context, ArrayList<navdraweritem> navDrawerItems){
this.context = context;
this.navDrawerItems = navDrawerItems;
}

@Override
public int getCount() {
return navDrawerItems.size();
}

@Override
public Object getItem(int position) {
return navDrawerItems.get(position);
}

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.drawer_list_item, null);
}

ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
TextView txtCount = (TextView) convertView.findViewById(R.id.counter);

imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());


// displaying count
// check whether it set visible or not
if(navDrawerItems.get(position).getCounterVisibility()){
txtCount.setText(navDrawerItems.get(position).getCount());
}else{
// hide the counter view
txtCount.setVisibility(View.GONE);
}

return convertView;
}

}
