Android自定义BaseAdapter看看小动物们在说啥

ListView自带上下滑动

这里也是根据大神学习的就不装逼了

布局文件：activity_main.xml

<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:orientation="vertical"tools:context=".MainActivity"><TextView
        android:layout_width="match_parent"android:layout_height="48dp"android:textSize="18sp"android:text="动物的世界你们不懂"android:gravity="center"/><ListView
        android:layout_width="match_parent"android:layout_height="wrap_content"android:id="@+id/list_animal"android:layout_gravity="center_horizontal" />
LinearLayout>

展示视图控制文件：MainActivity

}

写个Animal.java，大家不陌生吧

package run.yang.com.baseadapterdemo;/*** Created by yang_zzheng on 2016/7/14* yangzhizheng2012@163.com*/
public class Animal {private String aName;private String aSpeak;private int aIcon;public Animal() {}public Animal(String aName, String aSpeak, int aIcon) {this.aName = aName;this.aSpeak = aSpeak;this.aIcon = aIcon;}public String getaName() {return aName;}public String getaSpeak() {return aSpeak;}public int getaIcon() {return aIcon;}public void setaName(String aName) {this.aName = aName;}public void setaSpeak(String aSpeak) {this.aSpeak = aSpeak;}public void setaIcon(int aIcon) {this.aIcon = aIcon;}
}

自定义的BaseAdapter—->AnimalAdapter.java

package run.yang.com.baseadapterdemo;import android.content.Context;
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 java.util.LinkedList;/*** Created by yang_zzheng on 2016/7/14* yangzhizheng2012@163.com*/
public class AnimalAdapter extends BaseAdapter {private LinkedList mData;private Context mContext;public AnimalAdapter(LinkedList mData, Context mContext) {this.mData = mData;this.mContext = mContext;}@Overridepublic int getCount() {return mData.size();}@Overridepublic Object getItem(int position) {return null;}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {ViewHolder holder = null;if(convertView == null){convertView = LayoutInflater.from(mContext).inflate(R.layout.item_list_animal,parent,false);holder = new ViewHolder();holder.img_icon = (ImageView) convertView.findViewById(R.id.img_icon);holder.txt_aName = (TextView) convertView.findViewById(R.id.txt_aName);holder.txt_aSpeak = (TextView) convertView.findViewById(R.id.txt_aSpeak);convertView.setTag(holder);   //将Holder存储到convertView中}else{holder = (ViewHolder) convertView.getTag();}holder.img_icon.setBackgroundResource(mData.get(position).getaIcon());holder.txt_aName.setText(mData.get(position).getaName());holder.txt_aSpeak.setText(mData.get(position).getaSpeak());return convertView;}static class ViewHolder{ImageView img_icon;TextView txt_aName;TextView txt_aSpeak;}
}

当然少不了我们的列表项目布局item_list_animal.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="horizontal"><ImageView
        android:id="@+id/img_icon"android:layout_width="64dp"android:layout_height="64dp"android:baselineAlignBottom="true"android:paddingLeft="8dp" /><LinearLayout
        android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="vertical"><TextView
            android:id="@+id/txt_aName"android:layout_width="wrap_content"android:layout_height="wrap_content"android:paddingLeft="8dp"android:textColor="#1D1D1C"android:textSize="20sp" /><TextView
            android:id="@+id/txt_aSpeak"android:layout_width="wrap_content"android:layout_height="wrap_content"android:paddingLeft="8px"android:textColor="#B4B4B9"android:textSize="14sp" />LinearLayout>LinearLayout>

这里我们还添加了view_header.xml表头

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"android:gravity="center"><TextView
        android:layout_width="match_parent"android:layout_height="48dp"android:textSize="18sp"android:text="表头"android:gravity="center"android:background="#43BBEB"android:textColor="#FFFFFF"/>
LinearLayout>

这里我们还添加了view_footer.xml表尾

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"android:gravity="center"><TextView
        android:layout_width="match_parent"android:layout_height="48dp"android:textSize="18sp"android:text="表尾"android:gravity="center"android:background="#43BBEB"android:textColor="#FFFFFF"/>
LinearLayout>

我越往后学，感觉越来兴趣了，猪神真的很牛
