封装Activity

1、这是封装的Activity

package com.example.day2017_10_21demo;

import android.app.Application;
import android.os.Bundle;
import android.os.PersistableBundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;

/**
 * Created by 墨鸦 on 2017/10/21.
 */

public abstract class BaseActivity extends AppCompatActivity {
    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //设置内容视图
        setContentView(getLayout());

        findView();

        initData();

        setListener();

        setDrawlayoutListview();

        setFragment();
    }
    //获取布局的id
    public abstract int getLayout();
    //查找页面上的组件
    public abstract void findView();
    //初始化数据
    public abstract void initData();
    //设置监听
    public abstract void  setListener();
    //设置Drawlayout的列表适配器
    public abstract void setDrawlayoutListview();
    //动态添加fragment
    public abstract void setFragment();

}

2、这是实际运行的Activity继承上一个Activity

package com.example.day2017_10_21demo;

import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.FrameLayout;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.RelativeLayout;

import com.example.day2017_10_21demo.Fragment.FragmentMain;
import com.example.day2017_10_21demo.Fragment.FragmentSouye;

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends BaseActivity {

    private DrawerLayout drawerLayout;
    private FrameLayout frameLayout;
    private RelativeLayout drawerlayut_layout_left;
    private ImageView drawer_layout_left_img;
    private ListView drawer_layout_left_listview;
    private List<String> list=new ArrayList<String>();
    //获取布局的id
    @Override
    public int getLayout() {
        //加载的布局id
        return R.layout.activity_main;
    }
    //查找页面上的组件
    @Override
    public void findView() {
        //主页面的控件
        drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        frameLayout = (FrameLayout) findViewById(R.id.frame_layout);
        drawerlayut_layout_left = (RelativeLayout) findViewById(R.id.drawer_layout_left);
        drawer_layout_left_img = (ImageView) findViewById(R.id.drawer_layout_left_img);
        drawer_layout_left_listview = (ListView) findViewById(R.id.drawer_layout_left_listview);
    }
    //初始化数据
    @Override
    public void initData() {
        //给drawerlayout的listview设置数据
        list.add("钱包");
        list.add("行程记录");
        list.add("好友邀请");
        list.add("设置");
    }
    //设置监听
    @Override
    public void setListener() {
        //drawerlayout的listview的条目监听
        drawer_layout_left_listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                //关闭drawlayout视图
                drawerLayout.closeDrawer(drawerlayut_layout_left);
            }
        });
    }
    //设置Drawlayout的列表适配器
    @Override
    public void setDrawlayoutListview() {
        //设置android默认适配器
        ArrayAdapter<String> adapter=new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1,list);
        //添加适配器
        drawer_layout_left_listview.setAdapter(adapter);
    }

    @Override
    public void setFragment() {
        getSupportFragmentManager().beginTransaction().replace(R.id.frame_layout,new FragmentMain()).commit();
    }
}
