1、build.gradle 需要添加的内容

标注的颜色是新建项目之后，build.gradle文件需要添加的内容。

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.1'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'android-apt'
def AAVersion = '3.3.1'

repositories {
    jcenter()
}

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.lpc.test3.app"
        minSdkVersion 9
        targetSdkVersion 14
        versionCode 1
        versionName "1.0"
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_6
        targetCompatibility JavaVersion.VERSION_1_6
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'

}

dependencies {
    apt "org.androidannotations:androidannotations:$AAVersion"
    compile "org.androidannotations:androidannotations-api:$AAVersion"
}


apt {
    arguments {
        androidManifestFile variant.outputs[0].processResources.manifestFile
        // if you have multiple outputs (when using splits), you may want to have other index than 0

        // If you're using flavors you should use the following line instead of hard-coded packageName
        // resourcePackageName android.defaultConfig.packageName

        // You can set optional annotation processing options here, like these commented options:
        // logLevel 'INFO'
        // logFile '/var/log/aa.log'
    }
}



2、activity_main内容

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
        >
    <Button
            android:id="@+id/btn1"
            android:text="发送通知"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

    <Button
            android:layout_marginTop="10dp"
            android:layout_below="@id/btn1"
            android:id="@+id/btn2"
            android:text="清除通知"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>
</RelativeLayout>


3、MainActivity 内容



package com.lpc.test3.app;

import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import org.androidannotations.annotations.Click;
import org.androidannotations.annotations.EActivity;
import org.androidannotations.annotations.ViewById;

@EActivity(R.layout.activity_main)
public class MainActivity extends ActionBarActivity {

    @ViewById
    Button btn1;

    @ViewById
    Button btn2;

    @Click
    void btn1(View v){
        Toast.makeText(MainActivity.this,"大家好",Toast.LENGTH_LONG).show();
    }


}
