Android Wear:具有FragmentPagerAdapter的WearableActivity [英] Android Wear: WearableActivity with FragmentPagerAdapter

问题描述

使用WearableActivity时，您无法达到FragmentPagerAdapter所需的getSupportFragmentManager()，因此您需要使用getFragmentManager().

When using the WearableActivity you can't reach getSupportFragmentManager() which FragmentPagerAdapter requires, so you need to use getFragmentManager().

public MyWearActivity extends WearableActivity {

    public ArrayList<Fragment> mFragments;
    public ArrayList<String> mTitles;
    public ViewPager mViewPager;
    public PageFragmentPagerAdapter mPagerAdapter;

    @Override
    public void onCreate(Bundle b) {
        super.onCreate(b);
        setContentView(R.layout.main);
        fragments = new ArrayList<>();
        mTitles = new ArrayList<>();
        mViewPager = (ViewPager) findViewById(R.id.viewpager);

        mPagerAdapter = new PageFragmentPagerAdapter(getFragmentManager()); <-- PROBLEM

        // More code
    }
}

寻呼机适配器

public class PageFragmentPagerAdapter extends FragmentPagerAdapter {

    public PageFragmentPagerAdapter(FragmentManager fm) {

        super(fm); <-- PROBLEM

    }

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

    @Override
    public PageFragment getItem(int position) {
        return mFragments.get(position);
    }

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

在WearableActivity中使用FragmentPagerAdapter怎么办?

推荐答案

遇到了同样的问题.

我已经添加了它

compile 'com.android.support:support-v13:23.1+'

到build.gradle文件中的依赖项.然后在其中使用FragmentPagerAdapter添加

to the dependencies in the build.gradle file. Then where you use the FragmentPagerAdapter add

import android.support.v13.app.FragmentPagerAdapter;

不确定是否还有更好的方法.

Not sure if there's a better way yet.
