程式碼記錄在部落格上，分享給想我一樣的菜鳥們，自己忘了的時候也可以拿來看看，免得到處找程式碼：
Fragment中ListView的程式碼
package com.example.administrator.myapplication14.Fragment;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import 介面卡程式碼，我的Item內部有個頭像，點選頭像要跳轉到其他頁面。點選事件和跳轉傳值就寫在介面卡裡面：
package com.example.administrator.myapplication14.Adapter;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import com.example.administrator.myapplication14.Activity.Main2Activity;
import com.example.administrator.myapplication14.R;
import com.example.administrator.myapplication14.be.MessageCommend;
import java.util.List;

public class MyCommendAdapter extends BaseAdapter {
List<MessageCommend> mList;
Context mContext;
public MyCommendAdapter(Context context, List<MessageCommend> list) {
mList = list;
mContext = context;
}
@Override
public int getCount() {
return mList.size();
}
@Override
public Object getItem(int i) {
return mList.get(i);
}
@Override
public long getItemId(int i) {
return i;
}
ViewHolder mHolder;
@Override
public View getView(final int position, View view, ViewGroup viewGroup) {
mHolder = new ViewHolder();
if (view == null) {
view = LayoutInflater.from(mContext).inflate(R.layout.commend_state, null);
mHolder.mImageView = (ImageView) view.findViewById(R.id.commend_item_tou_xiang);
mHolder.tv1 = (TextView) view.findViewById(R.id.commend_item_name);
mHolder.tv2 = (TextView) view.findViewById(R.id.commend_item_content);
mHolder.tv3 = (TextView) view.findViewById(R.id.commend_item_time);
view.setTag(mHolder);
} else {
mHolder = (ViewHolder) view.getTag();
}
//如果沒有這些內容，將會顯示佈局檔案中的內容
mHolder.mImageView.setImageResource(R.mipmap.ic_launcher);
mHolder.tv1.setText(mList.get(position).getName());
mHolder.tv2.setText(mList.get(position).getText());
mHolder.tv3.setText(mList.get(position).getTime());
//頭像的點選事件並傳值
mHolder.mImageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//開始傳值
Intent intent=new Intent(mContext, Main2Activity.class);
Bundle bundle=new Bundle();
bundle.putSerializable("key",mList.get(position));
intent.putExtras(bundle);
//利用上下文開啟跳轉
mContext.startActivity(intent);
}
});
return view;
}
class ViewHolder {
ImageView mImageView;
TextView tv1;
TextView tv2;
TextView tv3;
}
}
佈局檔案如下只顯示下Itemde 佈局了：
<?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="wrap_content"
android:orientation="horizontal"
android:padding="10dp">
<!-- 訊息中心普通訊息的佈局 -->
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2">
<ImageView
android:id="@+id/commend_item_tou_xiang"
android:layout_width="45dp"
android:layout_height="45dp"
android:src="@drawable/messagescenter_at"/>
</RelativeLayout>
<!-- 姓名、訊息內容 -->
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="7"
android:orientation="vertical">
<!-- 姓名 -->
<TextView
android:id="@+id/commend_item_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="小凡"
android:textSize="18sp"/>
<!-- 訊息內容 -->
<TextView
android:id="@+id/commend_item_content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="小凡你好小凡你好小凡你好小凡你好小凡你好小凡你好"
android:singleLine="true"
android:textSize="14sp"/>
</LinearLayout>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2">
<!-- 接收訊息時間 -->
<TextView
android:id="@+id/commend_item_time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="2016-12"/>
</RelativeLayout>
</LinearLayout>在跳轉到的介面接收值：
TextView textView= (TextView) findViewById(R.id.textview333);
Intent intent=getIntent();
Bundle bundle=intent.getExtras();
if (bundle!=null){
mMessageCommend =
(MessageCommend) bundle.getSerializable("key");
}
textView.setText(mMessageCommend.getName());效果圖：
