android xUtils 2.6.14 jar 下载 使用 和混淆

一、ViewUtils

        你受够了重复冗长的findViewById了嘛？你受够了各种监听事件的绑定了嘛？在这里，你只需要一句注解，如@ViewInject、@OnClick，就能轻松摆脱小白似的代码，大大的上了一个档次。

二、HttpUtils

       支持的HTTP七种请求方式，非常便捷的满足你的接口请求的需要。同时还支持大文件上传下载，以及同步异步请求。

三、BitmapUtils

       你的程序因OOM强制关闭过嘛？你在为加在网络图片头疼嘛？有了组件，你将永久摆脱前面的问题。

四、DbUtils

       简单易用又出色的ORM框架，真的是谁用谁知道，直接轻松存储各种对象到sqlite数据库中，同时也能非常方便的进行各种条件查询，甚至分页查询，还有对表中数据的更新删除等操作，真正的实现。一行代码就可以进行增删改查。并且可通过注解自定义表名，列名，外键，唯一性约束，NOT NULL约束，CHECK约束等，支持事务。

先来看一看ViewUtils的代码：

//绑定布局文件
@ContentView(R.layout.activity_main)
public class MainActivity extends Activity {
     //绑定btn1的id
       @(R.id.Button01 )
       private Button btn1 ;
       @ViewInject(R.id.Button02 )
       private Button btn2 ;
       @ViewInject(R.id.button3 )
       private Button btn3 ;

       @Override
       protected void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);
             //绑定对象
            ViewUtils. inject(this);
      }
     //绑定按钮的监听器
       @OnChildClick({ R.id.Button01, R.id.Button02, R.id. button3 })
       private void onClick(View v) {
             switch (v.getId()) {
             case R.id.Button01 :
                  Toast. makeText(MainActivity.this, "Button1",Toast.LENGTH_SHORT).show();
                   break;
             case R.id.Button02 :
                  Toast. makeText(MainActivity.this, "Button2",Toast.LENGTH_SHORT).show();
                   break;
             case R.id.button3 :
                  startActivity( new Intent(MainActivity.this ,HttpActivity.class));
                   break;
             default:
                   break;
            }
      }

}

//绑定布局文件

             super.onCreate(savedInstanceState);
             //绑定对象
            ViewUtils. inject(this);
      }
     //绑定按钮的监听器
       @OnChildClick({ R.id.Button01, R.id.Button02, R.id. button3 })
       private void onClick(View v) {
             switch (v.getId()) {
             case R.id.Button01 :
                  Toast. makeText(MainActivity.this, "Button1",Toast.LENGTH_SHORT).show();
                   break;
             case R.id.Button02 :
                  Toast. makeText(MainActivity.this, "Button2",Toast.LENGTH_SHORT).show();
                   break;
             case R.id.button3 :
                  startActivity( new Intent(MainActivity.this ,HttpActivity.class));
                   break;

                   break;
            }
      }

}

二、HttpUtils

          list.add(pswNameValuePair);
          return list;

     }

}

三、BitmapUtils

第一：首先自定义application,初始化配置
public class BaseApplication extends Application {

***
* BitmpUtils BitmapGlobalConfig 配置缓存大小,储存位置 大小
*  BitmapdisplayConfig 配置图片的大小
* 以及设置默认图片,下载错误的图片
*
*
*/
     private BitmapGlobalConfig globalConfig;

     private BitmapDisplayConfig displayConfig;

     private static BaseApplication application;

     @Override
     public void onCreate() {
          super.onCreate();
          application = this;
          configBitmapParams();
     }
     //得到这个类的对象
     public static BaseApplication getApplication() {
          return application;
     }

     public void configBitmapParams() {
          /**
          * 单利模式初始化，并设置缓存的路径
          */
          globalConfig = BitmapGlobalConfig.getInstance(this, FileUtils.getAppImageCache());
          int cacheSize = (int) Runtime.getRuntime().maxMemory() / 8;
          // 设置缓存大小
          globalConfig.setMemoryCacheSize(cacheSize);

     }

     public BitmapGlobalConfig getGlobalConfig() {
          return globalConfig;
     }

     public void setGlobalConfig(BitmapGlobalConfig globalConfig) {
          this.globalConfig = globalConfig;
     }

     public BitmapDisplayConfig getDisplayConfig() {
          return displayConfig;
     }

     public void setDisplayConfig(BitmapDisplayConfig displayConfig) {
          this.displayConfig = displayConfig;
     }

}


第二步：加载数据、通知adapter更新、在adapter里面进行加载图片
private void loadData() {
          httpUtils.send(HttpMethod.GET, CommonURL.FRONT_IMAGE_TEST, new RequestCallBack() {

               @Override
               public void onSuccess(ResponseInfo responseInfo) {
                    String result = responseInfo.result;
                    try {
                         JSONObject jsonObject = new JSONObject(result);
                         JSONArray jsonArray = jsonObject.getJSONArray("items");
                         if (jsonArray != null && jsonArray.length() > 0) {
                              for (int j = 0; j < jsonArray.length(); j++) {
                                   Items items = Items.getFromJSON(jsonArray.getJSONObject(j));
                                   list.add(items);
                              }
                              adapter.notifyDataSetChanged();
                         }

                    } catch (JSONException e) {
                         e.printStackTrace();
                    }

               }

               @Override
               public void onFailure(HttpException error, String msg) {
                    LogUtils.e(msg);

               }
          });
     }


第三步

package com.qianfeng.bitmaputils.adapter;

import java.util.List;

import android.content.Context;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;

import com.lidroid.xutils.BitmapUtils;
import com.lidroid.xutils.ViewUtils;
import com.lidroid.xutils.view.annotation.ViewInject;
import com.qianfeng.bitmaputils.R;
import com.qianfeng.bitmaputils.bean.Items;

public class MainAdapter extends AppBaseAdapter {

     private BitmapUtils bitmapUtils;

     public MainAdapter(List list, Context context) {
          super(list, context);
     }

     public MainAdapter(List list, Context context, BitmapUtils bitmapUtils) {
          this(list, context);
          this.bitmapUtils = bitmapUtils;
     }

     @Override
     public View createView(int position, View convertView) {
          ViewHolder vh = null;
          if (convertView == null) {
               convertView = inflater.inflate(R.layout.fm_listview_item_layout, null);

               vh = new ViewHolder();
               ViewUtils.inject(vh, convertView);
               convertView.setTag(vh);
          } else {
               vh = (ViewHolder) convertView.getTag();
          }

          vh.contentTv.setText(list.get(position).getContent());
          vh.otherNameTv.setText(list.get(position).getLogin());
          bitmapUtils.display(vh.headIv, list.get(position).getImage());


//          bitmapUtils.display(container, uri, displayConfig, new )，这个方法里面有个回调监听器、可在这里设置进度条相关东西

          return convertView;
     }

     private static class ViewHolder {
          @ViewInject(R.id.headIv)
          ImageView headIv;
          @ViewInject(R.id.otherName)
          TextView otherNameTv;
          @ViewInject(R.id.content)
          private TextView contentTv;




     }

}

第一：首先自定义application,初始化配置
public class BaseApplication extends Application {

***
* BitmpUtils BitmapGlobalConfig 配置缓存大小,储存位置 大小
*  BitmapdisplayConfig 配置图片的大小
* 以及设置默认图片,下载错误的图片
*
*
*/

          application = this;
          configBitmapParams();
     }
     //得到这个类的对象
     public static BaseApplication getApplication() {
          return application;
     }

     public void configBitmapParams() {
          /**
          * 单利模式初始化，并设置缓存的路径
          */
          globalConfig = BitmapGlobalConfig.getInstance(this, FileUtils.getAppImageCache());
          int cacheSize = (int) Runtime.getRuntime().maxMemory() / 8;
          // 设置缓存大小
          globalConfig.setMemoryCacheSize(cacheSize);

     }

     public BitmapGlobalConfig getGlobalConfig() {
          return globalConfig;
     }

     public void setGlobalConfig(BitmapGlobalConfig globalConfig) {
          this.globalConfig = globalConfig;
     }

     public BitmapDisplayConfig getDisplayConfig() {
          return displayConfig;
     }

     public void setDisplayConfig(BitmapDisplayConfig displayConfig) {
          this.displayConfig = displayConfig;
     }

}


第二步：加载数据、通知adapter更新、在adapter里面进行加载图片
private void loadData() {
          httpUtils.send(HttpMethod.GET, CommonURL.FRONT_IMAGE_TEST, new RequestCallBack() {

               @Override
               public void onSuccess(ResponseInfo responseInfo) {
                    String result = responseInfo.result;
                    try {
                         JSONObject jsonObject = new JSONObject(result);
                         JSONArray jsonArray = jsonObject.getJSONArray("items");
                         if (jsonArray != null && jsonArray.length() > 0) {
                              for (int j = 0; j < jsonArray.length(); j++) {
                                   Items items = Items.getFromJSON(jsonArray.getJSONObject(j));
                                   list.add(items);
                              }
                              adapter.notifyDataSetChanged();
                         }

                    } catch (JSONException e) {
                         e.printStackTrace();
                    }

               }

               @Override
               public void onFailure(HttpException error, String msg) {
                    LogUtils.e(msg);

               }
          });
     }


第三步

package com.qianfeng.bitmaputils.adapter;

import java.util.List;

import android.content.Context;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;

import com.lidroid.xutils.BitmapUtils;
import com.lidroid.xutils.ViewUtils;
import com.lidroid.xutils.view.annotation.ViewInject;
import com.qianfeng.bitmaputils.R;
import com.qianfeng.bitmaputils.bean.Items;

public class MainAdapter extends AppBaseAdapter {

     private BitmapUtils bitmapUtils;

     public MainAdapter(List list, Context context) {
          super(list, context);
     }

     public MainAdapter(List list, Context context, BitmapUtils bitmapUtils) {
          this(list, context);
          this.bitmapUtils = bitmapUtils;
     }

     @Override
     public View createView(int position, View convertView) {
          ViewHolder vh = null;
          if (convertView == null) {
               convertView = inflater.inflate(R.layout.fm_listview_item_layout, null);
              
               vh = new ViewHolder();
               ViewUtils.inject(vh, convertView);
               convertView.setTag(vh);
          } else {
               vh = (ViewHolder) convertView.getTag();
          }

          vh.contentTv.setText(list.get(position).getContent());
          vh.otherNameTv.setText(list.get(position).getLogin());
          bitmapUtils.display(vh.headIv, list.get(position).getImage());
         
         
//          bitmapUtils.display(container, uri, displayConfig, new )，这个方法里面有个回调监听器、可在这里设置进度条相关东西
         
          return convertView;
     }

     private static class ViewHolder {
          @ViewInject(R.id.headIv)
          ImageView headIv;
          @ViewInject(R.id.otherName)
          TextView otherNameTv;
          @ViewInject(R.id.content)
          private TextView contentTv;
         
         
         

     }

}

XUtils混淆

第一：使用了ViewUtil的注解的监听事件，访问修饰符必须是public,否则混淆打包之后监听无效。

第二：在proguard-project中加入：

   -libraryjars libs/xUtils-2.6.14.jar 

   -keep class com.lidroid.** { *; } 

xUtils2.6.14.jar 和 source以及RecycleView-v7-24.1.1.jar 和source下载
