Android常用BaseActivity封装

嘿,今天的你过的还好吗,今天分享自己的BaseActivity内容,仅供参考
package com.example.mall.base;

     * 保证同一按钮在1秒内只会响应一次点击事件

        }
    }

    /**

     */
    @SuppressLint("ShowToast")

        try {

                }
            });
        } catch (Exception e) {
            e.printStackTrace();
            //解决在子线程中调用Toast的异常情况处理

    //活动管理器

        /**

         *

         */
        public static void addActivity(Activity activity) {

            activitys.add(activity);
        }

        /**
         * 从List中移除活动
         *
         * @param activity 活动
         */
        public static void removeActivity(Activity activity) {

            activitys.remove(activity);
        }

        /**
         * 将List中存储的活动全部销毁掉
         */
        public static void finishAll() {

            for (Activity activity : activitys) {

                if (!activity.isFinishing()) {

                    activity.finish();
                }
            }
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        //activity管理
        ActivityCollector.removeActivity(this);
    }
}

调用也很容易

public class MainActivity extends BaseActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        //设置是否显示标题栏
        setShowTitle(true);
        //设置是否显示状态栏
        setShowStatusBar(true);
        //是否允许屏幕旋转
        setAllowScreenRoate(true);
        //以上设置一定要在 super.onCreate(savedInstanceState) 方法之前设置
        super.onCreate(savedInstanceState);
    }
 
    @Override
    protected int initLayout() {
        //初始化布局
        return R.layout.activity_main;
    }
 
    @Override
    protected void initView() {
        //初始化控件
        Button button = new Button(context);
        button.setText("click");
        //每秒只响应一次点击事件
        button.setOnClickListener(new OnSingleClickListener() {
            @Override
            public void onSingleClick(View view) {
 
            }
        });
        //每秒可以重复响应点击事件
        button.setOnClickListener(new OnMultiClickListener() {
            @Override
            public void onMultiClick(View view) {
 
            }
        });
    }
 
    @Override
    protected void initData() {
 
        //初始化、绑定数据
    }
 
 
}

没更新动态或者频繁更新动态的时候都是在认真生活
