最近在使用Android studio，用到了androidannotations的库，但是有一些坑，为了记录一下，以备忘记。

annotation的配置
project的build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

今天和大家介绍下Android的懒人框架：annotation。
注意：很多人都添加了
上面的37行到42行的apt代码，导致不能使用，出现Cannot get property 'processResources' on null object 的错误，
其实只要把这几行代码删除就行了。但是之后还有问题，
The AndroidManifest.xml file contains the original component, and not the AndroidAnnotations generated component. Please register LoginActivity_ instead of LoginActivity
会报出这个问题，其实这个问题很蛋疼，只需要把原来的清单配置文件中的activity名字后面添加个“_”就行了。
之前名字是MainActivity，我给换成了“MainActivity_”.就好了。
见网址：http://www.4byte.cn/question/1068592/androidannotations2-7-1-androidmanifest-xml-file-contains-the-original-component.html
@EActivity
@EActivity(R.layout.main)
public class MyActivity extends Activity {
}
@EFragment
@EFragment(R.layout.my_fragment_layout)
public class MyFragment extends Fragment {
}
id="@+id/myFragment"
android:name="com.company.MyFragment_"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
MyFragment fragment = new MyFragment_();
@EBean
public class MyClass {
}
- 这个类必须仅仅只能有一个构造函数，参数最多有一个context
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@Bean
MyClass myClass;
}
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@Bean(MyClass.class)
MyClassInterface myClassInterface;
}
@EBean
public class MyClass {
@RootContext
Context context;
@RootContext
Activity activity;
@RootContext
Service service;
@RootContext
MyActivity myActivity;
}
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@AfterInject
public void doSomethingAfterInjection() {
}
}
- 如果想在类创建时期做一些操作可以这么做
@EBean(scope = Scope.Singleton)
public class MySingleton {
}
- 单例类
- 在单例类里面不可以注入view和事件绑定，因为单例的生命周期比Activity和Service的要长，以免发生内存溢出
@EView
@EView
public class CustomButton extends Button {
@App
MyApplication application;
@StringRes
String someStringResource;
public CustomButton(Context context, AttributeSet attrs) {
super(context, attrs);
}
}
<com.androidannotations.view.CustomButton_
android:layout_width="match_parent"
android:layout_height="wrap_content" />
CustomButton button = CustomButton_.build(context);
@EViewGroup
@EViewGroup(R.layout.title_with_subtitle)
public class TitleWithSubtitle extends RelativeLayout {
@ViewById
protected TextView title, subtitle;
public TitleWithSubtitle(Context context, AttributeSet attrs) {
super(context, attrs);
}
public void setTexts(String titleText, String subTitleText) {
title.setText(titleText);
subtitle.setText(subTitleText);
}
}

@EAplication
@EApplication
public class MyApplication extends Application {
}
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@App
MyApplication application;
}

@EService
public class MyService extends Service {

MyService_.intent(getApplication()).start();
MyService_.intent(getApplication()).stop()
@EReceiver
@EReceiver
public class MyReceiver extends BroadcastReceiver {

@EActivity(R.layout.main)
public class MyActivity extends Activity {
@Receiver(actions = "org.androidannotations.ACTION_1")
protected void onAction1() {
}
}
@EProvider
@EProvider
public class MyContentProvider extends ContentProvider {
}
@EViewById
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@ViewById
EditText myEditText;
@ViewById(R.id.myTextView)
TextView textView;
}
- 没有括号里定义的变量名称必须和布局的id名称一致
@EAfterViews
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@ViewById
TextView myTextView;
@AfterViews
void updateTextWithDate() {
myTextView.setText("Date: " + new Date());
}
}
一定要在这里进行view的一些设置，不要在oncreate()中设置，因为oncreate()在执行时 view还没有注入
@StringRes
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@StringRes(R.string.hello)
String myHelloString;
@StringRes
String hello;
}
- 不能将变量设置成私有变量
@ColorRes
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@ColorRes(R.color.backgroundColor)
int someColor;
@ColorRes
int backgroundColor;
}
@AnimationRes
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@AnimationRes(R.anim.fadein)
XmlResourceParser xmlResAnim;
@AnimationRes
Animation fadein;
}
@DimensionRes
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@DimensionRes(R.dimen.fontsize)
float fontSizeDimension;
@DimensionRes
float fontsize;
}
@DimensionPixelOffsetRes
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@DimensionPixelOffsetRes(R.string.fontsize)
int fontSizeDimension;
@DimensionPixelOffsetRes
int fontsize;
}
@DimensionPixelSizeRes
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@DimensionPixelSizeRes(R.string.fontsize)
int fontSizeDimension;
@DimensionPixelSizeRes
int fontsize;
}
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@Extra("myStringExtra")
String myMessage;
@Extra("myDateExtra")
Date myDateExtraWithDefaultValue = new Date();
}
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@Extra
String myMessage;
}
- The name of the extra will be "myMessage"，名字必须一致
MyActivity_.intent().myMessage("hello").start()
MyActivity_.intent().myMessage("hello").startForResult()
@SystemService
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@SystemService
NotificationManager notificationManager;
}
@HtmlRes
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@HtmlRes(R.string.hello_html)
Spanned myHelloString;
@HtmlRes
CharSequence helloHtml;
}
@FromHtml
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@ViewById(R.id.my_text_view)
@FromHtml(R.string.hello_html)
TextView textView;
@ViewById
@FromHtml
TextView hello_html;
}
- 必须用在TextView
@NonConfigurationInstance
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@NonConfigurationInstance
Bitmap someBitmap;
@NonConfigurationInstance
@Bean
MyBackgroundTask myBackgroundTask;
}
- 等同于Activity.onRetainNonConfigurationInstance()
@Click
@Click(R.id.myButton)
void myButtonWasClicked() {
}
@Click
void anotherButton() {
}
@Click
void yetAnotherButton(View clickedView) {
}
- LongClick和这个类似
@SeekBarProgressChange
@SeekBarProgressChange(R.id.seekBar)
void onProgressChangeOnSeekBar(SeekBar seekBar, int progress, boolean fromUser) {
}
@SeekBarProgressChange(R.id.seekBar)
void onProgressChangeOnSeekBar(SeekBar seekBar, int progress) {
}
@SeekBarProgressChange({R.id.seekBar1, R.id.seekBar2})
void onProgressChangeOnSeekBar(SeekBar seekBar) {
}
@SeekBarProgressChange({R.id.seekBar1, R.id.seekBar2})
void onProgressChangeOnSeekBar() {
}
- @SeekBarTouchStart 和 @SeekBarTouchStop 接受开始和结束事件的监听

@Background
void myMethod() {
someBackgroundWork("hello", 42);
}
@Background
void someBackgroundWork(String aParam, long anotherParam) {

- 后台运行
void myMethod() {
someCancellableBackground("hello", 42);
boolean mayInterruptIfRunning = true;
BackgroundExecutor.cancelAll("cancellable_task", mayInterruptIfRunning);
}
@Background(id="cancellable_task")

@Background(serial = "test")
void someSequentialBackgroundMethod(int i) {

}
- 非并发执行
@Background(delay=2000)
void doInBackgroundAfterTwoSeconds() {
}
- 延迟执行
@UIThread
void myMethod() {
doInUiThread("hello", 42);
}
@UiThread
void doInUiThread(String aParam, long anotherParam) {
}
- UI线程
@UiThread(delay=2000)
void doInUiThreadAfterTwoSeconds() {
}
- 延迟
@UiThread(propagation = Propagation.REUSE)
void runInSameThreadIfOnUiThread() {
}
- 优化UI线程
@EActivity(R.layout.main)
public class MyActivity extends Activity {
@Background
void doSomeStuffInBackground() {
publishProgress(0);
publishProgress(10);
publishProgress(100);
}
@UiThread

好了。关于annotation的介就是这么多。欢迎进群交流。还有，求工作啊！！！！
