[android]AndroidInject框架——我的第一個android小型框架

作為一個移動應用開發者，隨着需求的日益增多，Android項目的越來越臃腫，代碼量越來越大，

現在冷靜下來回頭看看我們的代碼，有多少代碼跟業務邏輯沒什么關系的

 

所以，本人自不量力，在github上建了個開源項目，希望能一定程度地簡化我的代碼-。-

現在第一個版本完成，希望有興趣的朋友能加入一起完善。

本人才疏學淺，代碼中有寫得不妥的地方希望大家不吝賜教哈！

github地址：

androidInject_1.0.jar：

主要的思想就是通過注解的方式，把我們要做的事情直接注入進來給我們，“不是我去調用對象，而是對象自己來找我”

現在剛寫完了10個注解：

@AINoTitle， @AIFullScreen， @AILayout， @AIView， @AIBean， @AISystemService， @AIClick， @AIItemClick， @AILongClick， @AIItemLongClick

使用方法如下：

Activity中使用：

package com.wangjie.androidinject;

import android.app.AlarmManager;
import android.content.Intent;
import android.location.LocationManager;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.*;
import com.wangjie.androidinject.annotation.annotations.*;
import com.wangjie.androidinject.annotation.present.AIActivity;
import com.wangjie.androidinject.model.Person;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

@AIFullScreen
@AINoTitle
@AILayout(R.layout.main)
public class MainActivity extends AIActivity{

    @AIView(id = R.id.btn1, clickMethod = "onClickCallback", longClickMethod = "onLongClickCallback")
    private Button btn1;

    @AIView(clickMethod = "onClickCallback", longClickMethod = "onLongClickCallback")
    private Button btn2;

//    @AIView(id = R.id.btn3)
//    private Button btn3;

//    @AIView(id = R.id.listView, itemClickMethod = "onItemClickCallback", itemLongClickMethod = "onItemLongClickCallbackForListView")
    @AIView(id = R.id.listView)
    private ListView listView;

    @AIBean
    private Person person;

    @AISystemService
    private AlarmManager alarmManager;
    @AISystemService
    private LocationManager locationManager;
    @AISystemService
    private LayoutInflater inflater;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        List<Map<String, String>> list = new ArrayList<Map<String, String>>();
        Map<String, String> map;
        for(int i = 0; i < 10; i++){
            map = new HashMap<String, String>();
            map.put("title", "item_" + i);
            list.add(map);
        }

        SimpleAdapter adapter = new SimpleAdapter(context, list, R.layout.list_item, new String[]{"title"}, new int[]{R.id.list_item_title_tv});
        listView.setAdapter(adapter);

        person.setName("wangjie");
        person.setAge(23);
        System.out.println(person.toString());

        System.out.println("alarmManager: " + alarmManager + ", locationManager: " + locationManager + ", inflater: " + inflater);


    }

    @Override
    public void onClickCallback(View view){
        if(view instanceof Button){
            Toast.makeText(context, "onClickCallback: " + ((Button)view).getText(), Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    public void onLongClickCallback(View view){
        if(view instanceof Button){
            Toast.makeText(context, "onLongClickCallback: " + ((Button)view).getText(), Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    public void onItemClickCallback(AdapterView<?> adapterView, View view, int i, long l) {
        Toast.makeText(context, "onItemClickCallback: " + ((Map<String, String>)adapterView.getAdapter().getItem(i)).get("title"), Toast.LENGTH_SHORT).show();
    }

    @AIClick({R.id.btn3, R.id.toFragmentBtn})
    public void onClickCallbackForBtn3(View view){
        if(view instanceof Button){
            Toast.makeText(context, "onClickForBtn3: " + ((Button)view).getText(), Toast.LENGTH_SHORT).show();
        }

        if(view.getId() == R.id.toFragmentBtn){
            startActivity(new Intent(context, SecendActivity.class));
        }

    }

    @AILongClick({R.id.btn3})
    public void onLongClickCallbackForBtn3(View view){
        if(view instanceof Button){
            Toast.makeText(context, "onLongClickCallbackForBtn3: " + ((Button)view).getText(), Toast.LENGTH_SHORT).show();
        }
    }

    @AIItemClick({R.id.listView})
    public void onItemClickCallbackForListView(AdapterView<?> adapterView, View view, int i, long l){
        Toast.makeText(context, "onItemClickCallbackForListView: " + ((Map<String, String>)adapterView.getAdapter().getItem(i)).get("title"), Toast.LENGTH_SHORT).show();
    }

    @AIItemLongClick(R.id.listView)
    public boolean onItemLongClickCallbackForListView(AdapterView<?> adapterView, View view, int i, long l) {
        Toast.makeText(context, "onItemLongClickCallbackForListView: " + ((Map<String, String>)adapterView.getAdapter().getItem(i)).get("title"), Toast.LENGTH_SHORT).show();
        return true;
    }



}

Fragment中使用：

package com.wangjie.androidinject;

import android.app.AlarmManager;
import android.os.Bundle;
import android.view.View;
import android.widget.*;
import com.wangjie.androidinject.annotation.annotations.*;
import com.wangjie.androidinject.annotation.present.AISupportFragment;
import com.wangjie.androidinject.model.Person;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

 */
@AILayout(R.layout.fragment_a)
public class FragmentA extends AISupportFragment{

    @AIView
    private Button fragmentABtn1;

    @AIView
    private GridView fragmentGv;

    @AIBean
    private Person person;

    @AISystemService
    private AlarmManager alarmManager;

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        List<Map<String, String>> list = new ArrayList<Map<String, String>>();
        Map<String, String> map;
        for(int i = 0; i < 10; i++){
            map = new HashMap<String, String>();
            map.put("title", "fragment_item_" + i);
            list.add(map);
        }

        SimpleAdapter adapter = new SimpleAdapter(context, list, R.layout.list_item, new String[]{"title"}, new int[]{R.id.list_item_title_tv});
        fragmentGv.setAdapter(adapter);

        person.setName("androidInject");
        person.setAge(1);
        System.out.println(person.toString());

        System.out.println("alarmManager: " + alarmManager);

    }

    @AIClick(R.id.fragmentABtn1)
    private void btnOnclick(View view){
        if(view instanceof Button){
            Toast.makeText(context, "btnOnclick: " + ((Button)view).getText(), Toast.LENGTH_SHORT).show();
        }
    }

    @AILongClick(R.id.fragmentABtn1)
    private void btnOnLongClick(View view){
        if(view instanceof Button){
            Toast.makeText(context, "btnOnLongClick: " + ((Button)view).getText(), Toast.LENGTH_SHORT).show();
        }
    }

    @AIItemClick(R.id.fragmentGv)
    private void gvOnItemClick(AdapterView<?> adapterView, View view, int i, long l){
        Toast.makeText(context, "gvOnItemClick: " + ((Map<String, String>)adapterView.getAdapter().getItem(i)).get("title"), Toast.LENGTH_SHORT).show();
    }

    @AIItemLongClick(R.id.fragmentGv)
    private void gvOnItemLongClick(AdapterView<?> adapterView, View view, int i, long l){
        Toast.makeText(context, "gvOnItemLongClick: " + ((Map<String, String>)adapterView.getAdapter().getItem(i)).get("title"), Toast.LENGTH_SHORT).show();
    }


}
