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}

moudle的build.gradle配置

apply plugin: '
com.android.application'
apply plugin: '
android-apt'
def AAVersion = '
4.0+'
repositories {
jcenter() flatDir {
dirs '
libs'
}
}
android {
compileSdkVersion 19 buildToolsVersion "23.0.2" defaultConfig {
applicationId "source.code.watch.film" minSdkVersion 14 targetSdkVersion 14 versionCode 1 versionName "1.0" }
buildTypes {
release {
minifyEnabled false proguardFiles getDefaultProguardFile('
proguard-android.txt'
), '
proguard-rules.pro'
}
}
signingConfigs {
debug {
storeFile file("E:\psd\debug.keystore") }
}
}
dependencies {
compile fileTree(include: ['
*.jar'
], dir: '
libs'
) apt "org.androidannotations:androidannotations:$AAVersion" compile "org.androidannotations:androidannotations-api:$AAVersion"}
apt {
arguments {
androidManifestFile variant.outputs[0].processResources.manifestFile resourcePackageName '
source.code.watch.film'
}
}

今天和大家介绍下Android的懒人框架：annotation。

@EActivity

@EActivity(R.layout.main)public class MyActivity extends Activity {
}

@EFragment

@EFragment(R.layout.my_fragment_layout)public class MyFragment extends Fragment {
}

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;
}

@EBeanpublic 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

@EViewpublic class CustomButton extends Button {
@App MyApplication application;
@StringRes String someStringResource;
public CustomButton(Context context, AttributeSet attrs) {
super(context, attrs);
}
}

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

@EApplicationpublic class MyApplication extends Application {
}

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

EService

@EServicepublic class MyService extends Service {
}

MyService_.intent(getApplication()).start();

MyService_.intent(getApplication()).stop();

@EReceiver

@EReceiverpublic class MyReceiver extends BroadcastReceiver {
}

@EActivity(R.layout.main)public class MyActivity extends Activity {
@Receiver(actions = "org.androidannotations.ACTION_1") protected void onAction1() {
}
}

@EProvider

@EProviderpublic 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;
}

@Extra

@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() {
}
@Clickvoid anotherButton() {
}
@Clickvoid 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

@TextChange

@TextChange(R.id.helloTextView) void onTextChangesOnHelloTextView(CharSequence text, TextView hello, int before, int start, int count) {
}
@TextChange void helloTextViewTextChanged(TextView hello) {
}
@TextChange({
R.id.editText, R.id.helloTextView}
) void onTextChangesOnSomeTextViews(TextView tv, CharSequence text) {
}
@TextChange(R.id.helloTextView) void onTextChangesOnHelloTextView() {
}

@BeforeTextChange

@BeforeTextChange(R.id.helloTextView) void beforeTextChangedOnHelloTextView(TextView hello, CharSequence text, int start, int count, int after) {
}
@BeforeTextChange void helloTextViewBeforeTextChanged(TextView hello) {
}
@BeforeTextChange({
R.id.editText, R.id.helloTextView}
) void beforeTextChangedOnSomeTextViews(TextView tv, CharSequence text) {
}
@BeforeTextChange(R.id.helloTextView) void beforeTextChangedOnHelloTextView() {
}

@AfterTextChange

@AfterTextChange(R.id.helloTextView) void afterTextChangedOnHelloTextView(Editable text, TextView hello) {
}
@AfterTextChange void helloTextViewAfterTextChanged(TextView hello) {
}
@AfterTextChange({
R.id.editText, R.id.helloTextView}
) void afterTextChangedOnSomeTextViews(TextView tv, Editable text) {
}
@AfterTextChange(R.id.helloTextView) void afterTextChangedOnHelloTextView() {
}

@Background

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

void myMethod() {
for (int i = 0;
i < 10;
i++) someSequentialBackgroundMethod(i);
}
@Background(serial = "test")void someSequentialBackgroundMethod(int i) {
SystemClock.sleep(new Random().nextInt(2000)+1000);
Log.d("AA", "value : " + i);
}
- 非并发执行

@Background(delay=2000)void doInBackgroundAfterTwoSeconds() {
}
- 延迟执行

@UIThread

void myMethod() {
doInUiThread("hello", 42);
}
@UiThreadvoid 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 void publishProgress(int progress) {
}
}
- 后台向UI线程传值

@OnActivityResult

@OnActivityResult(REQUEST_CODE)void onResult(int resultCode, Intent data) {
}
@OnActivityResult(REQUEST_CODE)void onResult(int resultCode) {
}
@OnActivityResult(ANOTHER_REQUEST_CODE)void onResult(Intent data) {
}
@OnActivityResult(ANOTHER_REQUEST_CODE)void onResult() {
}

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