需求：我们要点击进入一家店铺，根据不同的店铺，显示不同条数的子条目 如：消毒间，洗菜间等。。。这些都是或多或少的，所以需要动态添加：
首先自定义View(linearLayout):
package cn.qust.fang.widget;
import io.vov.vitamio.MediaPlayer;
import io.vov.vitamio.widget.MediaController;
import io.vov.vitamio.widget.VideoView;
import android.app.Activity;
import android.content.ContentResolver;
import android.content.ContentValues;
import android.content.Context;
import android.net.Uri;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;
import cn.qust.fang.CHANGLIANG.ChangLiang;
import cn.qust.fang.DB.DBManager;
import cn.qust.fang.domain.Shop;
import cn.qust.fang.main.MvplayActivity123;
import cn.qust.fang.main.R;
public class RightTopChildsLayouts extends LinearLayout {
Shop shop=null;
private TextView text_name_sub,textview_mvurl;
View view;
MvplayActivity123 currentactivity;
/**
* 配菜间 消毒间什么的
*/
String zi_name;
/** * 配菜间 消毒间的 的视频url
*/
String zi_mvurl;
public RightTopChildsLayouts(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
// TODO Auto-generated constructor stub
}
//自定义构造函数
public RightTopChildsLayouts(MvplayActivity123 context,Shop shop,String zi_name,String zi_mvurl){
super(context );
view = LayoutInflater.from(context).inflate(R.layout.sub_right_top, null);
text_name_sub=(TextView) view.findViewById(R.id.textview1);
/**
* 存mv_url
*/
textview_mvurl=(TextView) view.findViewById(R.id.textview_gone);
//把获得的view加载到这个控件中
addView(view);
this.currentactivity=context;
this.shop=shop;
this.zi_mvurl=zi_mvurl;
this.zi_name=zi_name;
text_name_sub.setText(zi_name);
textview_mvurl.setText(zi_mvurl);
view.setOnClickListener(new OnClickListener(){
//点击事件
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(!getZi_mvurl().equals("collect")){
//若不是收藏 就切换视频
System.out.println("点击=====RightTopChildsLayouts==zi_name========"+getZi_name());
VideoView mVideoView = currentactivity.getmVideoView();
mVideoView.pause();
Uri uri = Uri.parse(getZi_mvurl());
mVideoView.setVideoURI(uri);
mVideoView.start();
}
else {
/**
* 在这里进行收藏 如果已收藏 显示已收藏
*/
System.out.println("点击=收藏====RightTopChildsLayouts==zi_name========"+getZi_name());
if (getShop() == null)
Toast.makeText(getContext(), "收藏失败", Toast.LENGTH_SHORT).show();
if (!(new DBManager(getContext()).exits(getShop().getShop_id()))) {
save2db(getShop());
} else {
//Toast.makeText(context, "已收藏", Toast.LENGTH_SHORT).show();
text_name_sub.setText(R.string.haven_collected);
}
}
}
});
}
private void save2db(Shop shop) {
ContentResolver resolver = getContext().getContentResolver();
ContentValues values = new ContentValues();
// System.out.println("baocun11前--------");
values.put("shop_name", shop.getShopname());
values.put("address", shop.getAddress());
values.put("mv_url", shop.getMv_url());
values.put("logo_url", shop.getLogo_url());
values.put("msg", shop.getMsg());
values.put("shop_id", shop.getShop_id());
values.put("shop_phone", shop.getShop_phone());
Uri url = Uri
.parse("content://fang.ContentProvider.MyContentProvider_media/"
+ ChangLiang.TABLE);
resolver.insert(url, values);
// System.out.println("baocun11成功-----------");
// Toast.makeText(getContext(), "收藏成功", Toast.LENGTH_SHORT).show();
}
public Shop getShop() {
return shop;
}
public void setShop(Shop shop) {
this.shop = shop;
}
public String getZi_name() {
return zi_name;
}
public void setZi_name(String zi_name) {
this.zi_name = zi_name;
}
public String getZi_mvurl() {
return zi_mvurl;
}
public void setZi_mvurl(String zi_mvurl) {
this.zi_mvurl = zi_mvurl;
}
//这个可能不太合适
@Override
public void setOnClickListener(OnClickListener l) {
// TODO Auto-generated method stub
super.setOnClickListener(l);
// this.currentactivity.finish();
VideoView mVideoView = currentactivity.getmVideoView();
mVideoView.pause();
Uri uri = Uri.parse(zi_name);
mVideoView.setVideoURI(uri);
mVideoView.start();
mVideoView
.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
// optional need Vitamio 4.0
mediaPlayer.setPlaybackSpeed(1.0f);
}
});
}
}
上面用到的sub_right_top.xml如下：
<pre name="code" class="html"> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.aaaa.MainActivity"
tools:ignore="MergeRootFrame">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<!-- <ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="8dp"
android:src="@drawable/mm_title_btn_compose_normal" /> -->
<TextView
android:id="@+id/textview1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="8dp"
android:text="洗菜间"
android:textColor="#fff"
android:textSize="18sp" />
<TextView
android:id="@+id/textview_gone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="8dp"
android:text="隐藏"
android:textColor="#fff"
android:textSize="18sp"
android:visibility="gone"
/>
</LinearLayout>
</RelativeLayout>
下面是动态添加的代码：在他们的父布局一加载的时候开始动态添加：
public class MainTopRightDialog extends Activity {
// private MyDialog dialog;
private LinearLayout layout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_top_right_dialog);
// dialog=new MyDialog(this);
layout = (LinearLayout) findViewById(R.id.main_dialog_layout);
Shop shop1 = (Shop) getIntent().getSerializableExtra("shop_inmvplayer");
MvplayActivity123 mvplayActivity123 = MvplayActivity123.getinstance();
List<Map<String, Object>> mv_urls_list = null;
String mv_urls = shop1.getMv_url();
if (!mv_urls.equals("null") && mv_urls != null && !mv_urls.equals("")) {
try {
mv_urls_list = (List<Map<String, Object>>) new ParseJson2List()
.ParseJson2List(shop1.getMv_url().toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else {
mv_urls_list = null;
return;
}
RightTopChildsLayouts layout_childs = null;
/**
* 根据 zi_mvurl 区分是url 还是收藏 若是收藏就为 collect
*/
RightTopChildsLayouts layout_collect = null; ///
for (int i = 0; i < mv_urls_list.size(); i++) {
layout_childs = new RightTopChildsLayouts(mvplayActivity123, shop1,
mv_urls_list.get(i).get("_skey").toString(), mv_urls_list.get(i).get("_svalue").toString());
if (layout_childs != null) {
/* android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"*/
layout.addView(layout_childs,130,LinearLayout.LayoutParams.WRAP_CONTENT);
}
}
/**
* 添加收藏 项 若收藏过显示已收藏
*/
layout_collect=new RightTopChildsLayouts(mvplayActivity123, shop1,
(new DBManager(this).exits(shop1.getShop_id())?"已收藏":"收藏"), "collect");
layout.addView(layout_collect,130,LinearLayout.LayoutParams.WRAP_CONTENT);
/* layout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "提示：点击窗口外部关闭窗口！",
Toast.LENGTH_SHORT).show();
}
});*/
}
@Override
public boolean onTouchEvent(MotionEvent event) {
finish();
return true;
}
}这个的布局文件（main_dialog_layout）如下：<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="46dp"
>
<LinearLayout
android:id="@+id/main_dialog_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:orientation="vertical"
android:background="@drawable/title_function_bg" >
<!-- <LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="3dp"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="8dp"
android:text="收藏"
android:textColor="#fff"
android:textSize="18sp"
/>
</LinearLayout>
-->
</LinearLayout>
</RelativeLayout>
