#第二章：工具类封装与首页引导页开发
##一、log类的封装
    public class L {

    //开关
    public static final  boolean DEBUG = true;
    //TAG
    public static final String TAG = "SmartButler";

    //五个等级  DIWE

    public static void d(String text){
        if(DEBUG){
            Log.d(TAG,text);
        }
    }

    public static void i(String text){
        if(DEBUG){
            Log.i(TAG,text);
        }
    }

    public static void w(String text){
        if(DEBUG){
            Log.w(TAG,text);
        }
    }

    public static void e(String text){
        if(DEBUG){
            Log.e(TAG,text);
        }
    }
    }
##二、SharedPreferences的封装
    public class ShareUtils {
    public static final String NAME = "config";
    //键 值
    public static void putString(Context mContext,String key,String value){
        SharedPreferences sp = mContext.getSharedPreferences(NAME,Context.MODE_PRIVATE);
        sp.edit().putString(key,value).commit();
    }
    //键 默认值
    public static String getString(Context mContext,String key,String defValue){
        SharedPreferences sp = mContext.getSharedPreferences(NAME,Context.MODE_PRIVATE);
        return sp.getString(key,defValue);
    }
    //键 值
    public static void putInt(Context mContext,String key,int value){
        SharedPreferences sp = mContext.getSharedPreferences(NAME,Context.MODE_PRIVATE);
        sp.edit().putInt(key,value).commit();
    }
    //键 默认值
    public static int getInt(Context mContext,String key,int defValue){
        SharedPreferences sp = mContext.getSharedPreferences(NAME,Context.MODE_PRIVATE);
        return sp.getInt(key,defValue);
    }
    //键 值
    public static void putBoolean(Context mContext,String key,boolean value){
        SharedPreferences sp = mContext.getSharedPreferences(NAME,Context.MODE_PRIVATE);
        sp.edit().putBoolean(key,value).commit();
    }
    //键 默认值
    public static boolean getBoolean(Context mContext,String key,boolean defValue){
        SharedPreferences sp = mContext.getSharedPreferences(NAME,Context.MODE_PRIVATE);
        return sp.getBoolean(key,defValue);
    }
    //刪除 单个
    public static void deleShare(Context mContext,String key){
        SharedPreferences sp = mContext.getSharedPreferences(NAME,Context.MODE_PRIVATE);
        sp.edit().remove(key).commit();
    }
    //刪除 全部
    public static void deleAll(Context mContext){
        SharedPreferences sp = mContext.getSharedPreferences(NAME,Context.MODE_PRIVATE);
        sp.edit().clear().commit();
    }
    }
##三、设置字体
    
    public static void setFonts(Context context, TextView textView){
        Typeface typeface = Typeface.createFromAsset(context.getAssets(), "fonts/FONT.TTF");
        textView.setTypeface(typeface);
    }
##四、启动界面的逻辑处理
    public class SplashActivity extends Activity {
    private TextView tv_splash;
    Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case StaticClass.HANDLER_SPLASH:

                    if (isFirst()) {
                        //进入引导页面
                        Intent intent = new Intent(SplashActivity.this, GuideActivity.class);
                        startActivity(intent);
                    } else {
                        //进入主页面
                        Intent intent = new Intent(SplashActivity.this, MainActivity.class);
                        startActivity(intent);
                    }
                    finish();
                    break;
            }
            super.handleMessage(msg);
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);
        tv_splash = (TextView) findViewById(R.id.tv_splash);
        UtilTools.setFonts(SplashActivity.this, tv_splash);
        handler.sendEmptyMessageDelayed(StaticClass.HANDLER_SPLASH, 2000);
    }

    /**
     * 判断是否是第一次进入主页面
     *
     * @return
     */
    private boolean isFirst() {
        boolean isFirst = ShareUtils.getBoolean(this, StaticClass.SHARE_IS_FIRST, true);
        if (isFirst) {
            ShareUtils.putBoolean(this, StaticClass.SHARE_IS_FIRST, false);
            return true;
        } else {
            return false;
        }
    }
    }
##五、按钮的背景资源
    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false">
        <shape>
            <solid android:color="#009ad6"/>
            <corners android:radius="30dp"/>
        </shape>
    </item>

    <item android:state_pressed="true">
        <shape>
            <solid android:color="#76becc"/>
            <corners android:radius="30dp"/>
        </shape>
    </item>
    </selector>
##六、引导界面的完成
###界面布局：
     <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <android.support.v4.view.ViewPager
        android:id="@+id/mViewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="15dp"
        android:gravity="center"
        android:orientation="horizontal">

        <ImageView
            android:id="@+id/point1"
            android:layout_width="10dp"
            android:layout_height="10dp"/>

        <ImageView
            android:id="@+id/point2"
            android:layout_width="10dp"
            android:layout_height="10dp"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"/>

        <ImageView
            android:id="@+id/point3"
            android:layout_width="10dp"
            android:layout_height="10dp"/>
    </LinearLayout>

    <ImageView
        android:id="@+id/iv_back"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_marginRight="25dp"
        android:layout_marginTop="25dp"
        android:src="@drawable/black"/>

     </RelativeLayout>
###界面逻辑处理

    public class GuideActivity extends AppCompatActivity implements View.OnClickListener {

    private ViewPager mViewPager;
    //容器
    private List<View> mList = new ArrayList<>();
    private View view1, view2, view3;
    //小圆点
    private ImageView point1, point2, point3;
    //跳过
    private ImageView iv_back;

    private TextView tv_pager_1,tv_pager_2,tv_pager_3;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_guide);

        initView();
    }

    //初始化View
    private void initView() {

        point1 = (ImageView) findViewById(R.id.point1);
        point2 = (ImageView) findViewById(R.id.point2);
        point3 = (ImageView) findViewById(R.id.point3);

        iv_back= (ImageView) findViewById(R.id.iv_back);
        iv_back.setOnClickListener(this);
        //设置默认图片
        setPointImg(true, false, false);
        mViewPager = (ViewPager) findViewById(R.id.mViewPager);
        view1 = View.inflate(this, R.layout.pager_item_one, null);
        view2 = View.inflate(this, R.layout.pager_item_two, null);
        view3 = View.inflate(this, R.layout.pager_item_three, null);
        view3.findViewById(R.id.btn_start).setOnClickListener(this);

        tv_pager_1 = (TextView) view1.findViewById(R.id.tv_pager_1);
        tv_pager_2 = (TextView) view2.findViewById(R.id.tv_pager_2);
        tv_pager_3 = (TextView) view3.findViewById(R.id.tv_pager_3);

        UtilTools.setFont(this,tv_pager_1);
        UtilTools.setFont(this,tv_pager_2);
        UtilTools.setFont(this,tv_pager_3);

        mList.add(view1);
        mList.add(view2);
        mList.add(view3);

        //设置适配器
        mViewPager.setAdapter(new GuideAdapter());

        //监听ViewPager滑动
        mViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

            }

            //pager切换
            @Override
            public void onPageSelected(int position) {
                L.i("position:" + position);
                switch (position){
                    case 0:
                        setPointImg(true,false,false);
                        iv_back.setVisibility(View.VISIBLE);
                        break;
                    case 1:
                        setPointImg(false,true,false);
                        iv_back.setVisibility(View.VISIBLE);
                        break;
                    case 2:
                        setPointImg(false,false,true);
                        iv_back.setVisibility(View.GONE);
                        break;
                }
            }

            @Override
            public void onPageScrollStateChanged(int state) {

            }
        });
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn_start:
            case R.id.iv_back:
                startActivity(new Intent(this, MainActivity.class));
                finish();
                break;
        }
    }

    class GuideAdapter extends PagerAdapter {

        @Override
        public int getCount() {
            return mList.size();
        }
        @Override
        public boolean isViewFromObject(View view, Object object) {
            return view == object;
        }

        @Override
        public Object instantiateItem(ViewGroup container, int position) {
            ((ViewPager) container).addView(mList.get(position));
            return mList.get(position);
        }

        @Override
        public void destroyItem(ViewGroup container, int position, Object object) {
            ((ViewPager) container).removeView(mList.get(position));
            //super.destroyItem(container, position, object);
        }
    }

    //设置小圆点的选中效果
    private void setPointImg(boolean isCheck1, boolean isCheck2, boolean isCheck3) {
        if (isCheck1) {
            point1.setBackgroundResource(R.drawable.point_on);
        } else {
            point1.setBackgroundResource(R.drawable.point_off);
        }

        if (isCheck2) {
            point2.setBackgroundResource(R.drawable.point_on);
        } else {
            point2.setBackgroundResource(R.drawable.point_off);
        }

        if (isCheck3) {
            point3.setBackgroundResource(R.drawable.point_on);
        } else {
            point3.setBackgroundResource(R.drawable.point_off);
        }
    }
    }
###拿第三个引导界面的布局为例:
      <?xml version="1.0" encoding="utf-8"?>
     <RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:gravity="center"
        android:orientation="vertical">

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/guide_strong"/>

        <TextView
            android:layout_marginTop="10dp"
            android:id="@+id/tv_pager_3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="強大"
            android:textSize="50sp"/>
    </LinearLayout>
    <Button
        android:id="@+id/btn_start"
        android:layout_width="150dp"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="50dp"
        android:background="@drawable/button_bg"
        android:text="进入主页"
        android:textColor="@android:color/white"/>
    </RelativeLayout>
