@Annotation的混淆配置库Android快速开发库，Android常用工具集。任务管理、数据加载、下载库请查阅其他项目。
对于初学者欢迎加 QQ群:215621863 相互学习探讨！
本库的所有代码都经过本人严格测试，字斟句酌，了如指掌，注释也很清晰。覆盖Android基础开发的方方面面，推荐作为项目的基础框架来使用，以便于各功能的正常便利集成。有任何疑问或建议请联系作者： weichou2010@gmail.com、微信 或 加群@群主。
仅通过几个常量即可便捷的取得内置或外置存储卡 Storage.SdCard 对象。例如：
//输出外置存储卡的路径到logcat
if (Storage.CARD_EXT != null) L.i(this, Storage.CARD_EXT.path);
//是否可以在默认的卡上创建任意目录
if (Storage.CARD_DEF.isCustomDirCreatable(context)) {
//...
try {
File dir = FileUtils.makeDir(dirPath, true);
L.i(this, dir.getPath());
//...
} catch (FileCreateFailureException e) {
L.e(this, e);
}
}
仅有存储卡工具就够了吗？它需要去判断存储卡是否存在、能否创建目录和文件，再决定是否写文件。而FStoreLoc可以一步完成：
public static File getImagesCacheDir() throws SdCardNotMountedException,
SdCardNotValidException, FileCreateFailureException {
return FStoreLoc.BIGFILE.getImagesCacheDir(get(), DirLevel.CUSTOM);
}
DirLevel.CUSTOM
表示选择自定义根目录，只有在存储卡支持创建自定义目录时才有效，否则抛异常。当然也可选择私有目录
DirLevel.PRIVATE
或自适应目录 DirLevel.DEFAULT，详见代码中的文档。FStoreLoc有三种预置存储模式：
FStoreLoc.DEFAULT;FStoreLoc.BIGFILE;FStoreLoc.SURVIVE.而大文件模式和生存模式根据业务需要可能需要设置存储卡根目录，那就放在App初始化里：
public class App extends AbsApp {
@Override
public void onCreate() {
Debug.DEBUG = isDebugMode();
if (Debug.DEBUG) {
//...
}
super.onCreate();
//...
/* 设置大文件模式的文件根目录。若存储卡根目录允许写文件，则创建该目录，否则会使用存储卡上的
* 系统为App分配的私有目录：Android/appname/files/
* 大文件模式，即只存放在内置或外置存储卡上，外置优先。
*/
FStoreLoc.BIGFILE.setBaseDirName(this, Const.APP_DIR_NAME);
//切换到外置卡（默认会自动选择剩余空间最大的那张卡）。但是读写文件过程中如果不存在会自动切换到内置卡。
FStoreLoc.BIGFILE.switchTo(this, Storage.CARD_EXT);
}
//...
}
具有多进程读写安全、基于Locale的文件隔离能力等。
基本用法：
public final class XxxKeeper extends Keeper.Wrapper {
private static final String SPREF_NAME = "spref_name";
// 以下为固定写法
public static WrapperImpl get() {
return get(AbsApp.get().getApplicationContext(), SPREF_NAME);
}
public static final String KEY_VIEW_PEGER_INDEX = "view_peger_index";
private static final String KEY_XXX_JSON = "xxx_json";
// ...
public static void saveXxxObj(XxxObj entity) {
get()
.withLocale() // 根据需求可选
.multiProcess() // 根据需求可选
.edit() // 根据需求可选
.keepString(KEY_XXX_JSON, AbsJson.toJsonWithAllFields(entity));
// 如果上面的Api无法满足需求，可用原生的
.getSharedPreferences()
.putString(KEY_XXX_JSON, AbsJson.toJsonWithAllFields(entity))
.xxx();
}
public static XxxObj getXxxObj() {
try {
return AbsJson.fromJsonWithAllFields(
get()
.withLocale() // 根据需求可选
.multiProcess() // 根据需求可选
.edit() // 根据需求可选
.readString(KEY_XXX_JSON)
// 如果上面的Api无法满足需求，可用原生的
.getSharedPreferences()
.getString(KEY_XXX_JSON, null)
, XxxObj.clazz);
} catch (Exception e) {
return null;
}
}
}
// 或者这样使用
XxxKeeper.get().
.withLocale() // 根据需求可选
.multiProcess() // 根据需求可选
.edit() // 根据需求可选
.keepInt(XxxKeeper.KEY_VIEW_PEGER_INDEX, 1);
// 如果上面的Api无法满足需求，可用原生的
.getSharedPreferences()
.putInt(XxxKeeper.KEY_VIEW_PEGER_INDEX, 1)
.xxx();
示例：
@Override
protected void onResume() {
super.onResume();
NetConnectionReceiver.registerObserver(mNetObserver);
StorageReceiver.registerObserver(mToastStorageObserver);
//StorageReceiver.registerObserver(mStorageObserver);
}
@Override
protected void onPause() {
StorageReceiver.unregisterObserver(mToastStorageObserver);
//StorageReceiver.unregisterObserver(mStorageObserver);
NetConnectionReceiver.unregisterObserver(mNetObserver);
super.onPause();
}
private final NetObserver mNetObserver = new NetObserver() {
@Override
public void onChanged(Type type, State state) {
ensureViewState(true, false);
}
};
private final ToastStorageObserver mToastStorageObserver = new ToastStorageObserver(this);
private final StorageObserver mStorageObserver = new StorageObserver() {
/**按下"MediaButton"按键时发出的广播,假如有"MediaButton"按键的话(硬件按键)，
* Intent.EXTRA_KEY_EVENT携带了这个KeyEvent对象**/
protected void onMediaButton(KeyEvent ev) {}
/**已经插入，但是不能挂载**/

}
基于但简化了Broadcast和LocalBroadcast的发送/接收操作，在页面初始化的时候可以调用AbsActivity/AbsFragment.hostingLocalEventReceiver(...)将事件监听器进行托管，不再需要在onPause()、onResume()以及onDestroy()等事件的时候进行unregisterXxx()和registerXxx()编码，托管组件将自动完成。受惠于Broadcast的松散耦合机制和简化了的发送/接收操作，可将传统的Callack模式用本事件模式重构，轻松解决由于某些原因导致的资源无法释放和内存泄露等问题。示例：
//在Activity或Fragment中发送事件
@ViewLayoutId(R.layout.m_f_tabs_left_btn_page)
public class MTabsLeftFrgmt extends AbsFragment {
public void scroll2TopAndRefresh() {
//发送事件
sendLocalEvent(mRbtnRecommend.isChecked() ? Const.EventName.SCROLL_2_TOP_AND_REFRESH_frgmt_recommend
: Const.EventName.SCROLL_2_TOP_AND_REFRESH_frgmt_favorite, null);
}
//...
}
//在子Fragment中接收事件
@ViewLayoutId(R.layout.f_m_f_tabs_left_btn_page_recommend)
public class RecommendFrgmt extends AbsFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//只需要提前托管就好了，不用考虑onPause()、onResume()以及onDestroy()的时候还要取消注册或重新注册事件监听
hostingLocalEventReceiver(Const.EventName.SCROLL_2_TOP_AND_REFRESH_frgmt_recommend, PeriodMode.PAUSE_RESUME, new EventReceiver() {
@Override
public void onEvent(Bundle data) {
scroll2TopAndRefresh();
}
});
}
public void scroll2TopAndRefresh() {
L.i(this, "scroll2TopAndRefresh");
//TODO 这里需要处理多次连续调用的情况
}
}
@ViewOnClick的用法非常灵活。示例：
@ViewLayoutId(R.layout.m_edit)
public class EditActy extends AbsActivity implements OnClickListener {
@ViewOnClick // 当本类 implements OnClickListener, 那么直接加上本注解即可，不用参数
@ViewId(R.id.m_edit_title_left_btn_back)
private ImageButton mBtnBack;
@ViewId(value = R.id.m_edit_magic_board, visibility = View.GONE) // 多参数
private MagicBoardView mMagicBoard;
@ViewId(name = "m_edit_text", visibility = View.INVISIBLE) // 对于库项目，R.id.xxx非final的情况下，可写name字符串
private TextView mText;
//...
@Override
@ViewOnClick(@Ids(R.id.m_edit_magic_board)) // 若前面没有加@ViewOnClick, 也可以写在onClick()上面，参数也可以像下面这样
@ViewOnClick(@Ids({R.id.m_edit_title_left_btn_back, R.id.m_edit_magic_board}))
public void onClick(View v) {
switch (v.getId()) {
case R.id.m_acty_btn_download:
//...
break;
}
@ViewOnClick(@Ids({R.id.m_edit_title_left_btn_back, R.id.m_edit_magic_board})) // 或者可以写在任意自定义方法上面
private void myOnClick(View v) { // 这里也可以不用参数，像这样: private void myOnClick() {}
//...
}
@ViewOnClick(@Ids({R.id.m_edit_title_left_btn_back, R.id.m_edit_magic_board})) //甚至还可以这样，有没有觉得很cool
private OnClickListener mOnClickListener = new OnClickListener() {
@Override
public void onClick(View v) {
//...
}
};
}
示例：
/**由于typeKey可能全局都一样，做一个抽象**/
public abstract class AbsData<T extends AbsData<T>> extends AbsJsonTyped<T> {
public static final String KEY_RESULT = "result";
@Expose
public String result;
protected String typeKey() {
return KEY_RESULT;
}
}
/**构建与Json字符串对应的类结构**/
public class EditBean extends AbsData<EditBean> {
@Expose
public long id;
@Expose
public long topicId;
@Expose
public boolean favorite;
@Expose
public Info info;
public boolean selected = false;
public static class Info {
public Temp[] temps;
public int total_number;
}
public static class Temp {
public long mid;
public MagicBoardBody body;
public int forwarding_count;
public int classify;
public long start_time;
public long end_time;
public int collect;
}
public EditBean() {}
@Override
public int hashCode() {
return (int)id;
}
@Override
public boolean equals(Object o) {
EditBean fb = ((EditBean)o);
return fb.id == id && fb.topicId == topicId;
}
@Override
public EditBean fromJson(String json) {
return fromJsonWithExposeAnnoFields(json, getTypeToken());
}
@Override
public String toJson() {
return toJsonWithExposeAnnoFields(this);
}
@Override
protected String[] typeValues() {
return null;
}
@Override
protected TypeToken<EditBean> getTypeToken() {
return new TypeToken<EditBean>(){};
}
}
/*以下为操作数据*/
EditBean edit = new EditBean();
//edit.xxx = xxx;
//...
//序列化
edit.toJson();
//判断是否属于本类型，一般情况用不到。
if (new EditBean().isBelongToMe(new JSONObject(jsonString))) {
//...
}
//反序列化
new EditBean().fromJson(jsonString);
既可用于ListView的Adapter：
@Override
public View getView(int position, View convertView, ViewGroup parent) {
return EditGridViewHolder.getAndBindView(position, convertView, parent, getInflater(), EditGridViewHolder.class, getItem(position), mOnFavoriteClick);
}
//...
@ViewLayoutId(R.layout.i_m_edit)
public static class EditGridViewHolder extends ViewHolder<EditBean, OnClickListener> {
@ViewId(R.id.i_m_edit_magic_board)
private MagicBoardView mMagicBoard;
@ViewId(R.id.i_m_edit_cb_favorite)
private CheckBox mCBFav;
private Animation mAnimYes, mAnimNo;
private boolean mAnimYesStarted = false, mAnimNoStarted = false;
public EditGridViewHolder(View view) {
super(view);
}
@Override
protected void init(OnClickListener... args) {
mCBFav.setOnClickListener(args[0]);
}
@Override
public void bind(int position, EditListBean data) {
mCBFav.setTag(this);
MagicBoardUtils.display(getView().getContext(), mMagicBoard, data.magicBoard);
mPanelTranslucence.setVisibility(data.selected ? View.VISIBLE : View.GONE);
updateFavorite(false);
}
//...
}
也可用于ViewPager的PagerAdapter:
mViewPager.setAdapter(new PagerAdapter() {
@Override
public int getCount() {
return 5;
}
@Override
public boolean isViewFromObject(View view, Object obj) {
return view == ((ViewHolder<?, ?>)obj).getView();
}
@Override
public int getItemPosition(Object obj) {
int position = super.getItemPosition(obj);
if (obj instanceof ViewHolder4) {
position = 4;
} else if (obj instanceof ViewHolder3) {
position = 3;
} else if (obj instanceof ViewHolder2) {
position = 2;
} else if (obj instanceof ViewHolder1) {
position = 1;
} else if (obj instanceof ViewHolder0) {
position = 0;
}
return position;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
ViewHolder<Void, OnClickListener> vHolder = null;
switch (position) {
case 0:
vHolder = ViewHolder.bindView(0, ViewHolder.makeView(ViewHolder0.class, getLayoutInflater(), container), ViewHolder0.class, null, mOnNextClick);
break;
case 1:
vHolder = ViewHolder.bindView(0, ViewHolder.makeView(ViewHolder1.class, getLayoutInflater(), container), ViewHolder1.class, null, mOnNextClick);
break;
case 2:
vHolder = ViewHolder.bindView(0, ViewHolder.makeView(ViewHolder2.class, getLayoutInflater(), container), ViewHolder2.class, null, mOnNextClick);
break;
case 3:
vHolder = ViewHolder.bindView(0, ViewHolder.makeView(ViewHolder3.class, getLayoutInflater(), container), ViewHolder3.class, null, mOnNextClick);
break;
case 4:
vHolder = ViewHolder.bindView(0, ViewHolder.makeView(ViewHolder4.class, getLayoutInflater(), container), ViewHolder4.class, null, mOnCompleteClick);
break;
}
container.addView(vHolder.getView());
return vHolder;
}
@Override
public void destroyItem(ViewGroup container, int position, Object obj) {
container.removeView(((ViewHolder<?, ?>)obj).getView());
}
});
}
//...
@ViewLayoutId(R.layout.i_m_guide_next)
private static class ViewHolder0 extends ViewHolder<Void, OnClickListener> {
@ViewId(R.id.i_m_guide_bg)
protected View mBg;
@ViewId(R.id.i_m_guide_btn_next)
protected ImageButton mBtnNext;
protected static final int WIDTH = 720;
protected static final int HEIGHT = 1280;
protected static final int WIDTH_BTN = 224;
protected static final int HEIGHT_BTN = 88;
protected static final int RIGHT_BTN = 16;
protected static final int BOTTOM_BTN = 29;
public ViewHolder0(View view) {
super(view);
}
@Override
protected void init(OnClickListener... args) {
mBg.setBackgroundResource(R.drawable.img_i_m_guide_0);
mBtnNext.setTag(0);
mBtnNext.setOnClickListener(args[0]);
initBtnNextPosition();
}
@Override
public void bind(int position, Void data) {}
protected void initBtnNextPosition() {
int screenWidth = Device.getInstance(getView().getContext()).width;
int screenHeight = Device.getInstance(getView().getContext()).height;
RelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams) mBtnNext.getLayoutParams();
float widthScale = screenWidth * 1.0f / WIDTH;
float heightScale = screenHeight * 1.0f / HEIGHT;
lp.width = (int) (widthScale * WIDTH_BTN);
lp.height = (int) (heightScale * HEIGHT_BTN);
lp.rightMargin = (int) (widthScale * RIGHT_BTN);
lp.bottomMargin = (int) (heightScale * BOTTOM_BTN);
mBtnNext.setLayoutParams(lp);
}
}
private static class ViewHolder1 extends ViewHolder0 {
public ViewHolder1(View view) {
super(view);
}
@Override
protected void init(OnClickListener... args) {
mBg.setBackgroundResource(R.drawable.img_i_m_guide_1);
mBtnNext.setTag(1);
mBtnNext.setOnClickListener(args[0]);
initBtnNextPosition();
}
}
//...
还可用于其他任何场景：
public class Xxx {
@Override
public void onClick(View v) {
//弹出删除对话框
FavoriteDeleteViewHolder.showDeleteDialog(FavoriteActy.this, (ViewGroup)getWindow().getDecorView(), mOnDeleteClick);
}
//...
