Question

如何做出这样的东西？

？

对于我的应用程序，我想要一些图像按钮列表，如果我按下一个按钮，我想做一些事情。我真的在所有谷歌上搜索找到它，我找到了一些例子，但它们都太复杂了，而且有更多的细节

谁能给我一个关于如何制作简单的图像按钮列表的教程或示例？

制作按钮列表的一个简单方法是创建一个适配器。你可以通过做一些事情来使用它 list ButtonListAdapter buttonListAdapter = new ButtonListAdapter(context, List<"of whatever you send in">);.然后使用列表 list.setAdapter(buttonListAdapter);

class ButtonListAdapater  extends BaseAdapter
{
Context mContext;
private LayoutInflater mInflater;
List<"whatever you want to pass in such as images or textfiels or classes"> mDatas;

public ButtonListAdapater  (Context context, List<"whatever you want to pass in such as images or textfiels or classes"> results)
{
    mContext = context;
    mDatas = results;
    mInflater = LayoutInflater.from(mContext);
}

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

@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)
{
    ViewHolder holder;

    "whatever you want to pass in such as images or textfiels or classes" data = mDatas.get(position);

    if (convertView == null) {
                              "whatever layout you made, on click effect can be in layout on in code"
        convertView = mInflater.inflate(R.layout.data_list_item, null);

        holder = new ViewHolder();

        holder.tvButton = (TextView) convertView.findViewById(R.id.textViewButton);
        holder.lbButton = (ImageButton) convertView.findViewById(R.id.Button);

        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.tvButton.setText(data.getData());

    "With the button here it depends on what you want to do and how, since its perfectly fine to put an onclicklistener here or in the layout"
    holder.llButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(context, OTherActivity.class);
            startActivity(intent)
        }
     });


    return convertView;
}

static class ViewHolder
{
    TextView tvButton;
    ImageButton lbButton;
}

data_list_item 布局 xml 可以是一些简单的东西，例如

<?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" >
  <ImageButton
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:id="@+id/R.id.Button/>

 </LinearLayout>
