适配器代码

MyFragmentAdapter.java

打包com.example.buratinoapps.wallpaper.Adapter;

公共类MyFragmentAdapter扩展了FragmentPagerAdapter {

private Context context;

public MyFragmentAdapter(FragmentManager fm,Context context) {
    super(fm);
    this.context = context;
}

@Override
public Fragment getItem(int position) {
    if (position == 0)
        return CategoryFragment.getInstance();
    else if (position == 1)
        return DailyPopularFragment.getInstance();
    else if (position == 2)
        return RecentsFragment.getInstance();
    else return null;
}

@Override
public int getCount() {
    return 3;
}

// Ctrl+O


@Nullable
@Override
public CharSequence getPageTitle(int position) {
    switch (position) {
        case 0:
            return "Category";
        case 1:
            return "Daily Popular";
        case 2:
            return "Recents";
    }

    return "";

}

}

    if (INSTANCE == null)
        INSTANCE = new CategoryFragment();
    return INSTANCE;

Answer 1

提示在您的logcat的以下行中：

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.design.widget.TableLayout"

确保将设计库包含在gradle文件中：

compile 'com.android.support:design:28.0.0'

如果目标sdk不是28，请使用适当的库号来匹配您应用的sdk。
