AptIntent是一个Android平台基于annotation的库,其目的是简化创建带数据的Intent和获取Intent内的数据。
1.添加依赖
Gradle
在你的工程目录下的build.gradle
添加android-apt
插件,添加jitpack
的maven
库:
buildscript {
repositories {
jcenter()
}
dependencies {
...
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}
allprojects {
repositories {
...
maven { url "https://www.jitpack.io" }
}
}
然后在你的模块下的build.gradle
应用android-apt
插件,添加AptIntent依赖:
apply plugin: 'android-apt'
android {
...
}
dependencies {
compile 'com.github.zhl3391.AptIntent:aptintent:1.0.1'
apt 'com.github.zhl3391.AptIntent:aptintent-compiler:1.0.1'
}
2.定义接口
public interface IntentCreator {
String KEY_STRING = "string";
String KEY_INT = "int";
String KEY_BOOLEAN = "boolean";
String KEY_OBJECT = "object";
String KEY_ARRAY_LIST = "array_list";
String KEY_BUNDLE = "bundle";
@CreateIntent(MainActivity.class)
Intent mainActivityIntent(Context context,
Bundle bundle,
@Extra(KEY_STRING)String stringTest,
@Extra(KEY_INT) int intTest,
@Extra(KEY_BOOLEAN) boolean booleanTest,
@Extra(KEY_OBJECT) ObjectTest objectTest,
@Extra(KEY_ARRAY_LIST) ArrayList<String> arrayListTest);
}
定义一个IntentCreator
接口,定义一个mainActivityIntent
的方法,通过@CreateIntent
注解声明, 通过@Extra
注解声明参数。
注:必须传入Context
。
3.获取参数和跳转
public class MainActivity extends AppCompatActivity {
@ExtraField(KEY_STRING)
String mStringTest;
@ExtraField(KEY_INT)
int mIntTest;
@ExtraField(KEY_BOOLEAN)
boolean mBooleanTest;
@ExtraField(KEY_OBJECT)
ObjectTest mObjectTest;
@ExtraField(KEY_ARRAY_LIST)
ArrayList<String> mArrayListTest;
@ExtraField(KEY_BUNDLE)
String mBundleTest;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
AptIntent.bind(this);
}
public void jump(View view) {
ArrayList<String> arrayList = new ArrayList<>();
arrayList.add("arrayList");
Bundle bundle = new Bundle();
bundle.putString(KEY_BUNDLE, "bundle");
Intent intent = AptIntent.create(IntentCreator.class).mainActivityIntent(this,
bundle, "haha", 888, true, new ObjectTest(), arrayList);
startActivity(intent);
}
}
通过@ExtraField
注解声明成员变量,调用AptIntent.bind(this)
获取intent
内数据。
调用AptIntent.create(IntentCreator.class)
创建IntentCreator接口的实现,再调用mianActivityIntent
创建intent
。
注:@ExtraField
注解的成员变量不能用private
,static
修饰。
