Android BaseActivity和BaseFragment封装写法！

一，前言：在常用的APP中，大致也就是这种写法，平时开项目的时候也常用，所以写在这里。用的时候这复制，然后再根据具体的业务逻辑更改下。如下

BaseActivity

public abstract class BaseActivity extends AppCompatActivity {
    /***封装toast对象**/
    private static Toast toast;
    /***获取TAG的activity名称**/
    protected final String TAG = this.getClass().getSimpleName();
    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(setLyoutId());
        initLogger();
        initView();
        initDate();
    }
    public void initLogger(){
        Logger.init(TAG)    //LOG TAG默认是PRETTYLOGGER
                .methodCount(3)                 // 决定打印多少行（每一行代表一个方法）默认：2
                .hideThreadInfo()               // 隐藏线程信息 默认：显示
                .logLevel(LogLevel.NONE)        // 是否显示Log 默认：LogLevel.FULL（全部显示）
                .methodOffset(2);                // 默认：0
    }
    /**
     * 所有初始化的空间放这个里面。
     * @param
     */

    public abstract void initView();
    public abstract int setLyoutId();

    /**
     * 数据初始化
     */
    public abstract void initDate();
    @Override
    public void onRestart() {
        super.onRestart();
        Logger.d(TAG, "onRestart: 重启" );
    }

    @Override
    public void onStart() {
        super.onStart();
        Logger.d(TAG, "onRestart: 启动" );

    }

    @Override
    public void onResume() {
        super.onResume();
        Logger.d(TAG, "onRestart: 绘制" );

    }

    @Override
    public void onPause() {
        super.onPause();
        Logger.d(TAG, "onRestart: 暂停" );

    }

    @Override
    public void onStop() {
        super.onStop();
        Logger.d(TAG, "onRestart: 停止" );

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Log.d(TAG, "onRestart: 销毁" );

    }
    /**
     * 显示长toast
     * @param msg
     */
    public void tLong(String msg){
        if (null == toast) {
            toast = new Toast(this);
            toast.setDuration(Toast.LENGTH_LONG);
            toast.setText(msg);
            toast.show();
        } else {
            toast.setText(msg);
            toast.show();
        }
    }

    /**
     * 显示短toast
     * @param msg
     */

            toast = new Toast(this);
            toast.setDuration(Toast.LENGTH_SHORT);
            toast.setText(msg);
            toast.show();
        } else {
            toast.setText(msg);
            toast.show();
        }
    }


    /**
     * 跳转页面
     *
     * @param clz 所跳转的目的Activity类
     */
    public void startActivity(Class<?> clz) {
        startActivity(new Intent(this, clz));
    }

    /**
     * 跳转页面
     *

     * @param requestCode 请求码
     */
    public void startActivityForResult(Class<?> clz, int requestCode) {
        startActivityForResult(new Intent(this, clz), requestCode);
    }

    /**
     * 跳转页面
     *

 }

BaseFragment

public abstract class BaseFragment extends Fragment {
    protected BaseActivity mActivity;
    protected final String TAG = this.getClass().getSimpleName();

    @Override
    public void onAttach(Context Context) {
        super.onAttach(Context);
        mActivity = (BaseActivity) Context;
        Logger.d(TAG + "：onAttach：附加");
    }

    @Override
    public void setUserVisibleHint(boolean isVisibleToUser) {
        if (isVisibleToUser){
            Logger.d(TAG + "不涉及UI：setUserVisibleHint：可见");
        }
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Logger.d(TAG + "：onCreate");
    }

//    @Nullable

    @Nullable

    }

    @Override

        super.onViewCreated(view, savedInstanceState);

    }

    @Override

        super.onActivityCreated(savedInstanceState);
        initData(savedInstanceState);
        Logger.d(TAG + "：onActivityCreated:页面完成");

    }

    @Override
    public void onStart() {
        super.onStart();
        Logger.d(TAG + "：onStart: 启动");
        if (getUserVisibleHint()){//涉及到UI
            Logger.d(TAG + "：onStart: 涉及到UI的数据填充。");
            httpDate();
        }
    }

    @Override
    public void onResume() {

    }

        Logger.d(TAG + "：onStop: 停止");

    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        Logger.d(TAG + "：onDestroyView：销毁视图");

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Logger.d(TAG + "：onDestroy: 销毁整个页面");

    }

    @Override

//    protected abstract void init(View view);

    protected abstract void initData(Bundle savedInstanceState);

    /**
     * 需要更新UI的网络数据
     */
    protected abstract void httpDate();

这里，有一个脚手架，每次直接调用就可以了。github-BaseAndroid
