Android 复用自制的控件

项目每个页面都需要一个比较复杂的导航控件其实就是一个很多按钮的布局

当然这个一个一个写绑定事件完全没问题,但项目有20来个页面一个一个写就不好了,于是想到把他放到一widger包下那个页面用到了 include他的xml然后在Activity实例化他

FootView.java

[java]
package com.aijia.widget;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

import com.aijia.main.AijiaExitActivity;
import com.aijia.main.AijiaTabsActivity;
import com.aijia.main.R;
import com.aijia.main.AijiaIndexActivity;
import com.aijia.overall.Constant;

public class FootView {
    private Button index;
    private Button back;
    private Button shopcar;
    private Context context;
    private Button f_order;
    private Button f_exit;

    public FootView(Context context) {
        this.context = context;

    }

    public void init(View view) {

        index = (Button) view.findViewById(R.id.f_index);
        back = (Button) view.findViewById(R.id.f_back);
        shopcar = (Button) view.findViewById(R.id.f_shopcar);
        f_order = (Button) view.findViewById(R.id.f_order);
        f_exit = (Button) view.findViewById(R.id.f_exit);
        index.setOnClickListener(listener);
        back.setOnClickListener(listener);
        shopcar.setOnClickListener(listener);
        f_order.setOnClickListener(listener);
        f_exit.setOnClickListener(listener);
    }

    private OnClickListener listener = new OnClickListener() {

        @Override
        public void onClick(View v) {
            switch (v.getId()) {
            case R.id.f_index:
                gotoIntent(AijiaIndexActivity.class);
                break;
            case R.id.f_back:
                ((Activity) context).finish();
                break;
            case R.id.f_shopcar:
                Constant.CURRENTTABID = 3;
                gotoIntent(AijiaTabsActivity.class);
                break;
            case R.id.f_order:
                Constant.CURRENTTABID = 4;
                gotoIntent(AijiaTabsActivity.class);
                break;
            case R.id.f_exit:
                gotoIntent(AijiaExitActivity.class);
                break;
            default:
                break;
            }

        }
    };

    private void gotoIntent(Class<?> cls) {
        Intent intent = new Intent(context, cls);
        context.startActivity(intent);
        ((Activity) context).finish();
    }

}

如上可以进行跳转退出等操作注意他的init方法参数是一个view,哪里的view呢?我们看Activity调用他的代码
[java]
FootView footView = new FootView(context);
View roverall_footer = this.findViewById(R.id.overall_footer);
footView.init(roverall_footer);

这样的话就可以在应用中复用自己的控件了.
