現在很多流行的APP要表達的內容都很多，很多app為了節省布局資源，在listview 的靠右的部分加入了“更多”之類的字樣，提醒用戶點擊這里 可以看到跟多的內容，這樣整個listview要表達的內容就少了，看起來就要簡潔舒服。接下來我就為大家實現一下這個特效。先來看看效果，源碼放在最后供下載參看：  效果看完了，那就來一步一步實現這個效果。 1.布局代碼如下： 主布局： ~~~ <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:orientation="vertical" android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"> <ListView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/listView" android:layout_gravity="center_horizontal" /> </LinearLayout> ~~~ 單項布局： ~~~ <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="100dp"> <ImageView android:id="@+id/touXiang" android:background="#f00" android:layout_width="100dp" android:layout_height="match_parent" /> <TextView android:id="@+id/tv" android:layout_width="0dp" android:layout_weight="1" android:layout_height="match_parent"/> <Button android:id="@+id/more" android:layout_width="60dp" android:layout_height="match_parent" android:background="#ccc" android:text="更多"/> </LinearLayout> <LinearLayout android:id="@+id/moreLayout" android:layout_width="match_parent" android:layout_height="40dp" android:background="#aaa" android:gravity="center|center_horizontal"> <ImageButton android:id="@+id/dianZan" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <ImageButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/shoucang"/> </LinearLayout> </LinearLayout> ~~~ 效果如下：  2、主代碼如下： ~~~ package com.example.my.learnactionbarexample; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.widget.ListView; import java.util.ArrayList; public class MainActivity extends AppCompatActivity { private ListView lv; private item item; private ArrayList<item> items; private int[] touxiang ={R.drawable.touxiang1,R.drawable.touxiang2,R.drawable.touxiang3, R.drawable.touxiang4,R.drawable.touxiang5,R.drawable.touxiang6}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); lv = (ListView) findViewById(R.id.listView); items = new ArrayList<item>(); for (int i = 0; i < 6; i++) { item = new item(); item.setName("名字:"+i); item.setImg(touxiang[i]); item.setIsDianZan(false); items.add(item); } lv.setAdapter(new myAdapter(MainActivity.this,items)); } } ~~~ 自定義實體類如下： ~~~ package com.example.my.learnactionbarexample; /** * Created by Administrator on 2015/11/16. */ public class item { public Integer getImg() { return img; } public void setImg(Integer img) { this.img = img; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Boolean getIsDianZan() { return isDianZan; } public void setIsDianZan(Boolean isDianZan) { this.isDianZan = isDianZan; } private Integer img; private String name; private Boolean isDianZan; } ~~~ 實體類主要是封裝一些單項列表的數據，這個可以根據具體情況定義，我這拿點贊來做演示。 3、BaseAdapter的實現： ~~~ package com.example.my.learnactionbarexample; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.Button; import android.widget.ImageButton; import android.widget.ImageView; import android.widget.LinearLayout; import android.widget.TextView; import java.util.ArrayList; /** * Created by Administrator on 2015/11/16. */ public class myAdapter extends BaseAdapter { private Context context; private ArrayList<item> items; private LayoutInflater inflater; private Boolean[] isOpens = new Boolean[20]; public myAdapter(Context context, ArrayList<item> items) { this.context = context; this.items = items; inflater = LayoutInflater.from(context); for (int i = 0; i < items.size(); i++) { isOpens[i] = false; } } @Override public int getCount() { return items.size(); } @Override public Object getItem(int position) { return items.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder holder = null; if (convertView == null){ holder = new ViewHolder(); convertView = inflater.inflate(R.layout.list_item,null); holder.tv = (TextView) convertView.findViewById(R.id.tv); holder.touXiang = (ImageView) convertView.findViewById(R.id.touXiang); holder.more = (Button) convertView.findViewById(R.id.more); holder.ll = (LinearLayout) convertView.findViewById(R.id.moreLayout); holder.dianZan = (ImageButton) convertView.findViewById(R.id.dianZan); convertView.setTag(holder); }else { holder = (ViewHolder) convertView.getTag(); } holder.touXiang.setImageResource(items.get(position).getImg()); holder.tv.setText(items.get(position).getName()); if (items.get(position).getIsDianZan()){ holder.dianZan.setImageResource(R.drawable.dianzan1); }else { holder.dianZan.setImageResource(R.drawable.dianzan0); } holder.more.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (isOpens[position]) { isOpens[position] = false; notifyDataSetChanged(); } else { isOpens[position] = true; for (int i = 0; i < getCount(); i++) { if (i == position){ continue; } isOpens[i] = false; } notifyDataSetChanged(); } } }); if (isOpens[position]){ holder.ll.setVisibility(View.VISIBLE); }else { holder.ll.setVisibility(View.GONE); } holder.dianZan.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (items.get(position).getIsDianZan()){ items.get(position).setIsDianZan(false); }else { items.get(position).setIsDianZan(true); } notifyDataSetChanged(); } }); return convertView; } public final class ViewHolder{ private TextView tv; public ImageView touXiang; public Button more; public LinearLayout ll; public ImageButton dianZan; } } ~~~ [源碼下載地址](http://download.csdn.net/detail/oqihaogongyuan/9273377)
