Activity：

package com.example.mac.listviewandlistfragment.listview;

import android.os.Bundle;

import android.support.annotation.Nullable;

import android.support.v7.app.AppCompatActivity;

import android.view.View;

import android.widget.Button;

import android.widget.ListView;

import com.example.mac.listviewandlistfragment.R;

import java.util.ArrayList;

import java.util.List;

/**

* Created by mac on 16/9/1.

*/

public class ListViewActivity extends AppCompatActivity {

private ListViewBean lvb;

private List<ListViewBean> beanList;

private ListView lv;

private ListViewAdpter mAdapter;

private Button bt_add;

@Override

protected void onCreate(@Nullable Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.listview);

beanList = new ArrayList<>();

bt_add = (Button) findViewById(R.id.add_listview);

lv = (ListView) findViewById(R.id.listview);

//初始化模拟数据

for (int i = 0; i < 20; i++) {

//对象是地址引用的,改变其中一个数据,就会改变其他引用改对象的值,所以需要在for里面进行实例化

lvb = new ListViewBean();

lvb.setmName("listview");

lvb.setmChebox(false);

lvb.setmNumber(i + "");

lvb.setmImageURL("http://tupian.enterdesk.com/2013/mxy/0810/14/yoona%20%2812%29.jpg");

beanList.add(lvb);

}

mAdapter = new ListViewAdpter(this, beanList);

lv.setAdapter(mAdapter);

for (int i = 0; i < lv.getChildCount(); i++) {

View view = lv.getChildAt(i);

}

}

public void addView (View view){

lvb = new ListViewBean();

lvb.setmChebox(false);

lvb.setmName("添加的数据");

lvb.setmNumber(beanList.size() + "");

lvb.setmImageURL("http://tupian.enterdesk.com/2013/mxy/0810/14/yoona%20%2812%29.jpg");

beanList.add(lvb);

mAdapter.notifyDataSetChanged();

lv.setSelection(beanList.size()-1);

}

}
GlideCircleTransform（用于圆形的设置）：

package com.example.mac.listviewandlistfragment.listview;

import android.content.Context;

import android.graphics.Bitmap;

import android.graphics.BitmapShader;

import android.graphics.Canvas;

import android.graphics.Paint;

import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;

import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;

/**

* Created by mac on 16/9/1.

*/

public class GlideCircleTransform extends BitmapTransformation {

public GlideCircleTransform(Context context) {

super(context);

}

public GlideCircleTransform(BitmapPool bitmapPool) {

super(bitmapPool);

}

@Override

protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {

return circleCrop(pool, toTransform);

}

private static Bitmap circleCrop(BitmapPool pool, Bitmap source) {

if (source == null) return null;

int size = Math.min(source.getWidth(), source.getHeight());

int x = (source.getWidth() - size) / 2;

int y = (source.getHeight() - size) / 2;

// TODO this could be acquired from the pool too

Bitmap squared = Bitmap.createBitmap(source, x, y, size, size);

Bitmap result = pool.get(size, size, Bitmap.Config.ARGB_8888);

if (result == null) {

result = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);

}

Canvas canvas = new Canvas(result);

Paint paint = new Paint();

paint.setShader(new BitmapShader(squared, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));

paint.setAntiAlias(true);

float r = size / 2f;

canvas.drawCircle(r, r, r, paint);

return result;

}

@Override

public String getId() {

return getClass().getName();

}

}

listFragment篇：使用的是listview的adapter和数据，这个就是fragment加载适配器，Activity加载fragment；代码如下

listFragment：

package com.example.mac.listviewandlistfragment.lisetfragment;

import android.os.Bundle;

import android.util.Log;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ListView;

import com.example.mac.listviewandlistfragment.R;

import com.example.mac.listviewandlistfragment.listview.ListViewAdpter;

import com.example.mac.listviewandlistfragment.listview.ListViewBean;

import java.util.ArrayList;

import java.util.List;

/**

* Created by mac on 16/9/2.

*/

public class ListFragment1 extends android.app.ListFragment {

private ListViewBean lvb;

private List<ListViewBean> beanList=new ArrayList<>();

private ListViewAdpter mAdapter;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

//加载数据

for (int i = 0; i < 20; i++) {

lvb = new ListViewBean();

lvb.setmName("listview");

lvb.setmChebox(false);

lvb.setmNumber(i + "");

lvb.setmImageURL("http://tupian.enterdesk.com/2013/mxy/0810/14/yoona%20%2812%29.jpg");

beanList.add(lvb);

}

mAdapter = new ListViewAdpter(getActivity(), beanList);

}

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.fragemnt_list, null);

Log.d("shenYao","---------->onCreateView");

setListAdapter(mAdapter);

return view;

}

}

Activity：

package com.example.mac.listviewandlistfragment.lisetfragment;

import android.app.Activity;

import android.app.Fragment;

import android.app.FragmentManager;

import android.app.FragmentTransaction;

import android.os.Bundle;

import android.app.ListFragment;

import android.util.Log;

import android.view.View;

import android.widget.Button;

import com.example.mac.listviewandlistfragment.R;

/**

* Created by mac on 16/9/2.

*/

public class ListFragmentActivity extends Activity {

private Button button;

private FragmentTransaction transaction;

private FragmentManager manager;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.fragment);

button= (Button) findViewById(R.id.bt_zk);

manager=getFragmentManager();

transaction=manager.beginTransaction();

button.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

ListFragment fargment = new ListFragment1();

transaction.replace(R.id.replace, fargment);

transaction.commit();

}

});

}

}
