我這周上網(wǎng)看到動(dòng)態(tài)增加listview的每一項(xiàng)item的布局，今天抽空自己寫了一個(gè)，方便自己日后使用，這個(gè)效果還是很不錯(cuò)的，用到了Adapter的notifyDataSetChanged()方法，當(dāng)點(diǎn)擊每一個(gè)Item的時(shí)候，就通知adapter更新getView，系統(tǒng)得到通知就相應(yīng)的加載一遍布局，就達(dá)到了動(dòng)態(tài)加載item布局的效果。希望給大家?guī)睃c(diǎn)啟迪，有問題或想要代碼的可以留言，歡迎大家留言談?wù)搇istview的一些知識(shí)，以求共同進(jìn)步，轉(zhuǎn)載請(qǐng)標(biāo)明出處：

程序開啟界面，默認(rèn)選中貝貝item，點(diǎn)擊晶晶后的界面的效果，

點(diǎn)擊歡歡后界面的效果： 點(diǎn)擊迎迎后界面的效果：

點(diǎn)擊妮妮后界面的效果：

代碼奉上，真理還得看代碼：

在ListViewRunDemo工程中，

com.cn.daming包中的 MainActivity.java類中的代碼：

package com.cn.daming; import android.app.ListActivity; import android.content.Context; import android.os.Bundle; import android.view.Gravity; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.LinearLayout; import android.widget.TextView; public class MainActivity extends ListActivity { private ListAddLayoutAdapter mAdapter; @SuppressWarnings("unused") private LayoutInflater lInflater;; int[] image = { R.drawable.s_beibei, R.drawable.s_jingjing, R.drawable.s_huanhuan, R.drawable.s_yingying, R.drawable.s_nini }; String[] show_name = { "貝貝", "晶晶", "歡歡", "迎迎", "妮妮" }; private int id = 0; @SuppressWarnings("unused") private int last = 0; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mAdapter = new ListAddLayoutAdapter(this); this.setListAdapter(mAdapter); this.getListView().setOnItemClickListener(new OnItemClickListener(){ public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) { id = position; mAdapter.notifyDataSetChanged(); last = position; } }); } public class ListAddLayoutAdapter extends BaseAdapter { private Context context; private MainActivity activity; public ListAddLayoutAdapter(Context context) { this.context = context; this.activity = (MainActivity)context; lInflater = activity.getLayoutInflater(); } public int getCount() { return image.length; } public Object getItem(int arg0) { return null; } public long getItemId(int position) { return position; } public View getView(int position, View arg1, ViewGroup arg2) { LinearLayout layout = new LinearLayout(context); layout.setOrientation(LinearLayout.VERTICAL); layout.setPadding(0, 8, 0, 8); layout.addView(addTitleView(position)); if(id==position){ layout.addView(addCustomView(position)); } return layout; } public View addTitleView(int i){ LinearLayout layout = new LinearLayout(context); layout.setOrientation(LinearLayout.HORIZONTAL); ImageView iv = new ImageView(context); iv.setImageResource(image[i]); layout.addView(iv, new LinearLayout.LayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT)); TextView tv = new TextView(context); tv.setText(show_name[i]); tv.setTextSize(18f); layout.addView(tv, new LinearLayout.LayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT)); layout.setGravity(Gravity.CENTER); return layout; } public View addCustomView(int i){ View view = new View(context); switch(i){ case 0: ImageView iv1 = new ImageView(context); iv1.setImageResource(R.drawable.beibei); view = iv1; break; case 1: ImageView iv2 = new ImageView(context); iv2.setImageResource(R.drawable.jingjing); view = iv2; break; case 2: ImageView iv3= new ImageView(context); iv3.setImageResource(R.drawable.huanhuan); view = iv3; break; case 3: ImageView iv4 = new ImageView(context); iv4.setImageResource(R.drawable.yingying); view = iv4; break; case 4: ImageView iv5 = new ImageView(context); iv5.setImageResource(R.drawable.nini); view = iv5; break; } return view; } } }

說明：也可以動(dòng)態(tài)加載布局文件也可以的：

在addCustomView（）方法中這么寫也是可以的：

<span style="font-size: 16px;">case 1: view = lInflater.inflate(R.layout.main, null); break; </span>

工程的圖片沒有上傳，希望大家自己找些圖片就可以了：
