全功能技能，有错误待改进

一、build.gradle加依赖app/build.gradle:32

    compile project(':imageloaderlibrary')
    compile 'com.google.code.gson:gson:2.2.4'
    compile project(':pullToRefreshlibrary')
    compile 'com.github.andyoom:draggrid:v1.0.1'

二、AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application
    android:name="com.bwie.main.lianxi_01.app.imageloader"

三、创建基类Baseactivity与Basefragment

Baseactivity

//基类Activity
public abstract class BaseActivity extends AppCompatActivity{

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //创建一个方法
        init();
    }

    //初始化
    private void init() {
        setFullScreen();
        setContentView(initLayout());
        findView();
        setOnClickLisener();
        initData();
    }
    //设置点击事件
    protected abstract void setOnClickLisener();

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

    //查找控件
    protected abstract void findView();

    //设置全屏
    protected abstract void setFullScreen();

    //填充布局
    protected abstract int initLayout();

    //全屏
    protected void fullScreen() {
        // 设置全屏
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }
}

Basefragment

//基类Fragment
public abstract class BaseFragment extends Fragment{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        //Inflate the layout for this fragment
        return initLayout(inflater, container);
    }

    //填充布局
    protected abstract View initLayout(LayoutInflater inflater, ViewGroup container);

4、activity_main

activity_main.xml 5秒跳转到 activity_show.xml ，实现渐变效果

public class MainActivity extends BaseActivity implements Animation.AnimationListener{

    //渐变动画
    private AlphaAnimation alphaAnimation;
    //根布局
    private RelativeLayout rlSplash;

    @Override
    protected void setOnClickLisener() {

    }

    @Override
    protected void initData() {
        //设置渐变时间
        alphaAnimation = new AlphaAnimation(0, 1);
        //设置跳转时间
        alphaAnimation.setDuration(2000);
        //设置跳转方法
        alphaAnimation.setAnimationListener(this);
        //开始渐变
        rlSplash.startAnimation(alphaAnimation);
    }

    @Override
    protected void findView() {
        //初始化控件
        rlSplash = (RelativeLayout) findViewById(R.id.rl_splash);
    }

    @Override
    protected void setFullScreen() {
        fullScreen();
    }

    @Override
    protected int initLayout() {
        return R.layout.activity_main;
    }

    @Override
    public void onAnimationStart(Animation animation) {

    }

    @Override
    public void onAnimationEnd(Animation animation) {
        //跳转
        Intent intent = new Intent(MainActivity.this,ShowActivity.class);
        startActivity(intent);
        finish();
    }

    @Override
    public void onAnimationRepeat(Animation animation) {

    }
}

        list = new ArrayList<>();
        list.add(fragment1);
        list.add(fragment2);
        list.add(fragment3);
        list.add(fragment4);
        //创建适配器+设置适配器
        adapterf = new MyFragmentAdapter(getSupportFragmentManager(),list);
        view_pager.setAdapter(adapterf);
        //滑动viewpager，按钮跟着改变。
        view_pager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

            }

            @Override
            public void onPageSelected(int position) {
                radio_group.check(radio_group.getChildAt(position).getId());
            }

            @Override
            public void onPageScrollStateChanged(int state) {

            }
        });
        //点击按钮，viewpager跟着改变。
        radio_group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) {
                switch (checkedId){
                    case R.id.dd1:
                        view_pager.setCurrentItem(0);
                        break;

            }
        });

    }

    @Override
    protected void initData() {
        // 选中第一个页面
