安卓EActivity的佈局xml和Activity綁定

 添加定義：

def AAVersion = '4.4.0'

添加依賴：

annotationProcessor "org.androidannotations:androidannotations:$AAVersion"
implementation "org.androidannotations:androidannotations-api:$AAVersion"

apply plugin: 'com.android.application'
def AAVersion = '4.4.0'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.ndktest"
        minSdkVersion 20
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        ndk {
            moduleName "hello" 
            abiFilters "armeabi-v7a", "x86"
            ldLibs("log")
        }

        javaCompileOptions {
            annotationProcessorOptions {
                arguments = [resourcePackageName: project.getName()]
            }
        }

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

//    externalNativeBuild{
//        cmake{
//            path "src/main/jni/CMakeLists.txt"
//            version "3.10.2"
//        }
//    }

    sourceSets {
        main() {
            jniLibs.srcDirs = ['src/main/libs']
            jni.srcDirs = [] 
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    annotationProcessor "org.androidannotations:androidannotations:$AAVersion"
    implementation "org.androidannotations:androidannotations-api:$AAVersion"
}

在Activity中使用：

@EActivity(R.layout.activity_main)

package com.example.ndktest;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;

import org.androidannotations.annotations.EActivity;

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


    TextView tv_main;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        tv_main=findViewById(R.id.tv_main);
        tv_main.setText(Hello.sayHello());
    }
}
