가로 스크롤 가능 메뉴로 사용되는 가로 스크롤 가능 ListView이 필요합니다.HListView의 항목을 HorizontalListView를 사용하여 클릭 할 수 없습니다.
나는 해결책을 찾고 나서 this library을 찾았다.
에 it.sephiroth.android.library.widget.HListView 개체에 it.sephiroth.android.library.widget.AdapterView.OnItemClickListener을 구현하려고합니다.
목록을 채울 수는 있지만 항목에 리스너를 연결할 수없는 것처럼 보입니다. 나는 이것을 알아 내기 위해 이틀 동안 노력했지만 아무런 게임도하지 않았다. 이 기능은 여전히 작동하지 않습니다. 이 내 viewitem.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#800000"
android:clickable="false"
android:focusable="false"
android:orientation="vertical" >
<ImageButton
android:id="@+id/ibScrollMenuImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#800000"
android:clickable="false"
android:focusable="false"
android:scaleType="centerCrop" />
<TextView
android:id="@+id/tvScrollMenuTitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="false"
android:focusable="false"
android:gravity="center_horizontal"
android:textColor="#f4f4f4" />
</LinearLayout>
입니다
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#800000"
android:descendantFocusability="blocksDescendants" >
<it.sephiroth.android.library.widget.HListView
android:id="@+id/hlvPlacesListScrollMenu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/transparent"
android:scrollbars="none"
android:divider="@android:color/transparent"
/>
이 내 main_activity_layout된다 그래서
이 fragment_layout.xml 내 DialogFragment의 XML입니다 .. 구원에 대한 기존의 WWW로 전환
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/llDialogFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#34f34f"
android:orientation="vertical"
tools:context=".MainActivity" >
</LinearLayout>
매우 기본입니다.
내 MainActicity은 다음과 같습니다
package com.example.hscrollviewtest;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
LifeStatsDialogFragment menuFragment = new LifeStatsDialogFragment();
ft.add(R.id.llDialogFragment, menuFragment).commit();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Dialogfrgment의 된 .java :
package com.example.hscrollviewtest;
import it.sephiroth.android.library.widget.AdapterView;
import it.sephiroth.android.library.widget.AdapterView.OnItemClickListener;
import it.sephiroth.android.library.widget.HListView;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class LifeStatsDialogFragment extends DialogFragment implements
OnItemClickListener {
private HListView scroll;
private View rootView;
private HorizontalScrollMenuAdapter mAdapter;
final String[] IMAGE_TITLE = new String[] { "Home", "Work", "School",
"Sport" };
final int[] MENU_IMAGES = new int[] { R.drawable.ic_circle_home,
R.drawable.ic_circle_work, R.drawable.ic_circle_school,
R.drawable.ic_circle_gym };
public LifeStatsDialogFragment newInstance() {
return new LifeStatsDialogFragment();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
rootView = inflater.inflate(R.layout.fragment_layout, container, false);
mAdapter = new HorizontalScrollMenuAdapter(getActivity(),
R.layout.fragment_layout, R.id.tvScrollMenuTitle, IMAGE_TITLE,
MENU_IMAGES);
scroll = (HListView) rootView
.findViewById(R.id.hlvPlacesListScrollMenu);
scroll.setAdapter(mAdapter);
scroll.invalidate();
scroll.setOnItemClickListener(this);
for (int i = 0; i < scroll.getAdapter().getCount(); i++) {
Log.i(this.getClass().getSimpleName(), "first item in scroll : "
+ scroll.getChildAt(i) + "and its clickable?? "
+ scroll.getAdapter().getItemViewType(i) + "\n");
}
Log.i(this.getClass().getSimpleName(),
"The number of children for HlistView is: "
+ scroll.getParent().toString());
return rootView;
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
}
}
와 (나는 HorizontalVariableListViewDemo에서 사용할 때 작동하는)이 어댑터입니다 :
package com.example.hscrollviewtest;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.ArrayAdapter;
import android.widget.ImageButton;
import android.widget.TextView;
public class HorizontalScrollMenuAdapter extends ArrayAdapter<String>{
private String[] mButtonText;
private int[] mIconId;
private final String TAG = this.getClass().getSimpleName();
//Constructor
public HorizontalScrollMenuAdapter(Context context, int resource,
int textViewResourceId, String[] menuItemName, int[] menuItemImage) {
super(context, resource, textViewResourceId, menuItemName);
// TODO Auto-generated constructor stub
mButtonText = menuItemName;
mIconId = menuItemImage;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return mIconId.length;
}
@Override
public String getItem(int position) {
// TODO Auto-generated method stub
return null;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater mInflater = (LayoutInflater) parent.getContext().getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.viewitem, null);
holder = new ViewHolder();
holder.name = (TextView) convertView.findViewById(R.id.tvScrollMenuTitle);
holder.icon=(ImageButton) convertView.findViewById(R.id.ibScrollMenuImage);
//holder.icon.setBackgroundResource(android.R.color.transparent);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
holder.name.setText(mButtonText[position]);
holder.icon.setImageResource(mIconId[position]);
holder.icon.setTag(mIconId[position]);
Log.d(TAG,"returned view to fragment");
return convertView;
}
static class ViewHolder{
TextView name;
ImageButton icon;
}
}
여러분 중 한 명이 내 맹점을 볼 수 있기를 바랍니다. Thaks
보기를 만들 때 어댑터 내부에서 클릭 리스너를 설정해보십시오. – Mikel
