BaseActivity的简单方法

不做过多的解释，直接上代码
这里先唠叨一句（初级的开发工程师，写代码一定要规范，注释要简洁，命名一定要规范，因为以后可能维护的项目不是你本人，你要对自己曾经写的代码负责，让继承者有一个舒适感，维护起来也很 easy）。

activity的用法

package com.hfga.myapplication.activity;

import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;

import com.hfga.myapplication.Base.BaseActivity;
import com.hfga.myapplication.R;

import butterknife.BindView;
import butterknife.ButterKnife;
import butterknife.OnClick;

public class MainActivity extends BaseActivity {

    @BindView(R.id.tv_back)
    TextView tvBack;
    @BindView(R.id.tv_intos)
    TextView tvIntos;
    private TextView tv_backs;
    private TextView tv_intoss;

    @Override
    public void initParms(Bundle parms) {
        setState(true); //设置是否隐藏状态栏
        setScreenRoate(true);
    }

    @Override
    public View bindView() {
        return null;
    }

    @Override
    public int bindLayout() {
        return R.layout.activity_main;
    }


    @Override
    public void initView(View view) {
    }

    @Override
    public void doBusiness(Context mContext) {

    }


    @Override
    public void onPointerCaptureChanged(boolean hasCapture) {
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // TODO: add setContentView(...) invocation
        ButterKnife.bind(this);
    }

    @OnClick({R.id.tv_back, R.id.tv_intos})
    public void onViewClicked(View view) {
        switch (view.getId()) {
            case R.id.tv_back:
                toastLong(MainActivity.this,"退出舞台。");
                finish();
                break;
            case R.id.tv_intos:
                toastLong(MainActivity.this,"开始show。");
                startActivity(DetialActivity.class);
