Setting wallpaper from image URL when loaded into view

Question

I have set up my app to load lots of images/wallpapers from an external source/link then load those images into view so the user can scroll through them.

I am wanting to make it so once the user clicks on the image they have in view, it will then set is as their wallpaper.

Here's my class:

public class Question extends FragmentActivity implements OnClickListener {
private static final String IMAGE_CACHE_DIR = "images";
public static final String EXTRA_IMAGE = "extra_image";

private ImagePagerAdapter mAdapter;
private ImageFetcher mImageFetcher;
private ViewPager mPager;

@TargetApi(11)
@Override
public void onCreate(Bundle savedInstanceState) {
    if (BuildConfig.DEBUG) {
        Utils.enableStrictMode();
    }
    super.onCreate(savedInstanceState);
    setContentView(R.layout.image_detail_pager);

    AdView ad = (AdView) findViewById(R.id.ad);
    ad.loadAd(new AdRequest());

    final DisplayMetrics displayMetrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
    final int height = displayMetrics.heightPixels;
    final int width = displayMetrics.widthPixels;

    final int longest = (height > width ? height : width) / 2;

    ImageCache.ImageCacheParams cacheParams = new ImageCache.ImageCacheParams(
            this, IMAGE_CACHE_DIR);
    cacheParams.setMemCacheSizePercent(0.25f);

    mImageFetcher = new ImageFetcher(this, longest);
    mImageFetcher.addImageCache(getSupportFragmentManager(), cacheParams);
    mImageFetcher.setImageFadeIn(false);

    mAdapter = new ImagePagerAdapter(getSupportFragmentManager(),
            Images.imageUrlsQuestion.length);
    mPager = (ViewPager) findViewById(R.id.pager);
    mPager.setAdapter(mAdapter);
    mPager.setPageMargin((int) getResources().getDimension(
            R.dimen.image_detail_pager_margin));
    mPager.setOffscreenPageLimit(2);

    getWindow().addFlags(LayoutParams.FLAG_FULLSCREEN);

    if (Utils.hasHoneycomb()) {
        final ActionBar actionBar = getActionBar();

        actionBar.setDisplayShowTitleEnabled(false);
        actionBar.setDisplayHomeAsUpEnabled(true);

        mPager.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
            @Override
            public void onSystemUiVisibilityChange(int vis) {
                if ((vis & View.SYSTEM_UI_FLAG_LOW_PROFILE) != 0) {
                    actionBar.hide();
                } else {
                    actionBar.show();
                }
            }
        });

        mPager.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
        actionBar.hide();
    }

    final int extraCurrentItem = getIntent().getIntExtra(EXTRA_IMAGE, -1);
    if (extraCurrentItem != -1) {
        mPager.setCurrentItem(extraCurrentItem);
    }
}

@Override
public void onResume() {
    super.onResume();
    mImageFetcher.setExitTasksEarly(false);
}

@Override
protected void onPause() {
    super.onPause();
    mImageFetcher.setExitTasksEarly(true);
    mImageFetcher.flushCache();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    mImageFetcher.closeCache();
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case android.R.id.home:
        NavUtils.navigateUpFromSameTask(this);
        return true;
    case R.id.clear_cache:
        mImageFetcher.clearCache();
        Toast.makeText(this, R.string.clear_cache_complete_toast,
                Toast.LENGTH_SHORT).show();
        return true;
    }
    return super.onOptionsItemSelected(item);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main_menu, menu);
    return true;
}

public ImageFetcher getImageFetcher() {
    return mImageFetcher;
}

private class ImagePagerAdapter extends FragmentStatePagerAdapter {
    private final int mSize;

    public ImagePagerAdapter(FragmentManager fm, int size) {
        super(fm);
        mSize = size;
    }

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

    @Override
    public Fragment getItem(int position) {
        return ImageDetailFragment
                .newInstance(Images.imageUrlsQuestion[position]);
    }
}

@TargetApi(11)
@Override
public void onClick(View v) {
    final int vis = mPager.getSystemUiVisibility();
    if ((vis & View.SYSTEM_UI_FLAG_LOW_PROFILE) != 0) {
        mPager.setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
    } else {
        mPager.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
    }
}
}

Do you think you should at least prompt a dialog to ask the user whether or not they want to set it as wallpaper? — AndroidBegin.com, Sep 27 '13 at 08:25
Yes I also wanted to do that, I wanted this question to be as simplified as possible, would that be too complicated? — Jack, Sep 27 '13 at 08:27

Take a look in Set Wallpaper using WallpaperManager here and don't forget to add the below permission to your Manifest:

     <uses-permission android:name="android.permission.SET_WALLPAPER"/>
