Question

目前我正在尝试使用Fragments进行应用程序介绍，我成功创建了它。以下是片段应用程序介绍的屏幕截图，我没有上传所有3个屏幕截图：

第一个问题：如何在其中实现flycopageIndicator：

还有其他简单方法吗？

第二个问题：我在某个应用程序中看到，当我滑动片段时，下一个转换为完成如何做到这一点？第三个问题：我想模糊我的应用程序的图像。我知道它可能在Java中，但在我的代码中如何？

MainActivity.java

public class MainActivity extends AppCompatActivity {
private TabLayout tabLayout;
private ViewPager viewPager;
private FlycoPageIndicaor mFlycoPageIndicaor;

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


    viewPager = (ViewPager) findViewById(R.id.viewpager);
    setupViewPager(viewPager);

}

private void setupViewPager(ViewPager viewPager) {
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
    adapter.addFragment(new OneFragment(), "ONE");
    adapter.addFragment(new TwoFragment(), "TWO");
    adapter.addFragment(new ThreeFragment(), "THREE");
    viewPager.setAdapter(adapter);
}

class ViewPagerAdapter extends FragmentPagerAdapter {
    private final List<Fragment> mFragmentList = new ArrayList<>();
    private final List<String> mFragmentTitleList = new ArrayList<>();

    public ViewPagerAdapter(FragmentManager manager)
    {
        super(manager);
    }

    @Override
    public Fragment getItem(int position) {
        return mFragmentList.get(position);
    }

    @Override
    public int getCount() {
        return mFragmentList.size();
    }

    public void addFragment(Fragment fragment, String title) {
        mFragmentList.add(fragment);
        mFragmentTitleList.add(title);
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return mFragmentTitleList.get(position);
    }


}
}

activity_main.xml中

OneFragment.java

public class OneFragment extends android.support.v4.app.Fragment {


public void OneFragment(){

}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.one_fragment, container, false);
}}

one_fragment.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

<TextView
    android:text="TextView"

<ImageView

    android:scaleType="centerCrop"
    android:layout_toStartOf="@+id/textView3"
    android:id="@+id/imageView2"
    android:layout_alignParentEnd="true"/>

TwoFragment.java和ThreeFragment.java与OneFragment.java具有相同的代码

two_fragment.xml和three_fragment.xml与one_fragment.xml具有相同的代码，具有不同的可绘制图像

如何在AndroidFragment中使用FlycoPageIndicator？
