BaseActivity基本封装

开始新项目前的准备工作

一、BaseActivity类的基本封装，减少代码重复量

二、管理activity关系

BaseActivity.java:

public abstract class BaseActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ActivityController.addActivity(this);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        ActivityController.removeActivity(this);
    }

    //初始化控件
    protected abstract void initView();

    //初始化数据
    protected abstract void initData();

    //设置适配器
    protected abstract void setAdapter();

    //设置监听事件
    protected abstract void initEvent();

    //通过类名启动Activity
    protected void openActivity(Class pClass) {
        openActivity(pClass, null);
    }

    //通过类名启动Activity并携带Bundle数据
    protected void openActivity(Class pClass, Bundle pBundle) {
        Intent intent = new Intent(this, pClass);
        if (pBundle != null) {
            intent.putExtras(pBundle);
        }
        startActivity(intent);
    }

    //通过action启动Activity
    protected void openActivity(String pAction) {
        openActivity(pAction, null);
    }

    //通过action启动Activity并携带Bundle数据
    protected void openActivity(String pAction, Bundle pBundle) {
        Intent intent = new Intent(pAction);
        if (pBundle != null) {
            intent.putExtras(pBundle);
        }
        startActivity(intent);
    }

    //结束所有Activity允许子类调用
    protected void finishAll() {
        ActivityController.finishAll();
    }

}

ActivityController.java:

public class ActivityController {
    private static List activities = new ArrayList();


    //加入activity
    public static void addActivity(Activity activity) {
        activities.add(activity);
    }

    //移除某个activity
    public static void removeActivity(Activity activity) {
        activities.remove(activity);
    }

    //结束所有activity
    public static void finishAll() {
        //遍历activity
        for (Activity activity : activities) {
            if (!activity.isFinishing()) {
                activity.finish();
            }
        }
    }

}
