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：

[java] view plain copy print ?

1. //绑定布局文件
2. @ContentView(R.layout.activity_main)
3. public class MainActivity extends Activity {
4. //绑定btn1的id
5. @(R.id.Button01 )
6. private Button btn1 ;
7. @ViewInject(R.id.Button02 )
8. private Button btn2 ;
9. @ViewInject(R.id.button3 )
10. private Button btn3 ;
12. @Override
13. protected void onCreate(Bundle savedInstanceState) {
14. super.onCreate(savedInstanceState);
15. //绑定对象
16. ViewUtils. inject(this);
17. }
18. //绑定按钮的监听器
19. @OnChildClick({ R.id.Button01, R.id.Button02, R.id. button3 })
20. private void onClick(View v) {
21. switch (v.getId()) {
22. case R.id.Button01 :
23. Toast. makeText(MainActivity.this, "Button1",Toast.LENGTH_SHORT).show();
24. break;
25. case R.id.Button02 :
26. Toast. makeText(MainActivity.this, "Button2",Toast.LENGTH_SHORT).show();
27. break;
28. case R.id.button3 :
29. startActivity( new Intent(MainActivity.this ,HttpActivity.class));
30. break;
31. default:
32. break;
33. }
34. }
36. }

三、BitmapUtils
[java] view plain copy print ?

1. 第一：首先自定义application,初始化配置
2. public class BaseApplication extends Application {
4. ***
5. * BitmpUtils BitmapGlobalConfig 配置缓存大小,储存位置 大小
6. *BitmapdisplayConfig 配置图片的大小
7. * 以及设置默认图片,下载错误的图片
8. *
9. *
10. */
11. private BitmapGlobalConfig globalConfig;
13. private BitmapDisplayConfig displayConfig;
15. private static BaseApplication application;
17. @Override
18. public void onCreate() {
19. super.onCreate();
20. application = this;
21. configBitmapParams();
22. }
23. //得到这个类的对象
24. public static BaseApplication getApplication() {
25. return application;
26. }
28. public void configBitmapParams() {
29. /**
30. * 单利模式初始化，并设置缓存的路径
31. */
32. globalConfig = BitmapGlobalConfig.getInstance(this, FileUtils.getAppImageCache());
33. int cacheSize = (int) Runtime.getRuntime().maxMemory() / 8;
34. // 设置缓存大小
35. globalConfig.setMemoryCacheSize(cacheSize);
37. }
39. public BitmapGlobalConfig getGlobalConfig() {
40. return globalConfig;
41. }
43. public void setGlobalConfig(BitmapGlobalConfig globalConfig) {
44. this.globalConfig = globalConfig;
45. }
47. public BitmapDisplayConfig getDisplayConfig() {
48. return displayConfig;
49. }
51. public void setDisplayConfig(BitmapDisplayConfig displayConfig) {
52. this.displayConfig = displayConfig;
53. }
55. }
58. 第二步：加载数据、通知adapter更新、在adapter里面进行加载图片
59. private void loadData() {
60. httpUtils.send(HttpMethod.GET, CommonURL.FRONT_IMAGE_TEST, new RequestCallBack() {
62. @Override
63. public void onSuccess(ResponseInfo responseInfo) {
64. String result = responseInfo.result;
65. try {
66. JSONObject jsonObject = new JSONObject(result);
67. JSONArray jsonArray = jsonObject.getJSONArray("items");
68. if (jsonArray != null && jsonArray.length() > 0) {
69. for (int j = 0; j < jsonArray.length(); j++) {
70. Items items = Items.getFromJSON(jsonArray.getJSONObject(j));
71. list.add(items);
72. }
73. adapter.notifyDataSetChanged();
74. }
76. } catch (JSONException e) {
77. e.printStackTrace();
78. }
80. }
82. @Override
83. public void onFailure(HttpException error, String msg) {
84. LogUtils.e(msg);
86. }
87. });
88. }
91. 第三步
93. package com.qianfeng.bitmaputils.adapter;
95. import java.util.List;
97. import android.content.Context;
98. import android.view.View;
99. import android.widget.ImageView;
100. import android.widget.TextView;
102. import com.lidroid.xutils.BitmapUtils;
103. import com.lidroid.xutils.ViewUtils;
104. import com.lidroid.xutils.view.annotation.ViewInject;
105. import com.qianfeng.bitmaputils.R;
106. import com.qianfeng.bitmaputils.bean.Items;
108. public class MainAdapter extends AppBaseAdapter {
110. private BitmapUtils bitmapUtils;
112. public MainAdapter(List list, Context context) {
113. super(list, context);
114. }
116. public MainAdapter(List list, Context context, BitmapUtils bitmapUtils) {
117. this(list, context);
118. this.bitmapUtils = bitmapUtils;
119. }
121. @Override
122. public View createView(int position, View convertView) {
123. ViewHolder vh = null;
124. if (convertView == null) {
125. convertView = inflater.inflate(R.layout.fm_listview_item_layout, null);
127. vh = new ViewHolder();
128. ViewUtils.inject(vh, convertView);
129. convertView.setTag(vh);
130. } else {
131. vh = (ViewHolder) convertView.getTag();
132. }
134. vh.contentTv.setText(list.get(position).getContent());
135. vh.otherNameTv.setText(list.get(position).getLogin());
136. bitmapUtils.display(vh.headIv, list.get(position).getImage());
139. //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
141. return convertView;
142. }
144. private static class ViewHolder {
145. @ViewInject(R.id.headIv)
146. ImageView headIv;
147. @ViewInject(R.id.otherName)
148. TextView otherNameTv;
149. @ViewInject(R.id.content)
150. private TextView contentTv;
155. }
157. }

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; }}

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
【android xUtils 2.6.14 jar 下载 使用 和混淆】
