I'm using the PhotoView library to have a slide view of images. That's easy. Then I wanted set as wallpaper the image I wanted, maybe on click in a button but I have a problem! The library seems that not allows create a layout but only its in this way.
<com.ex.paper.HackyViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
So i can't add any button. I need detect the right array position and in some way set that image as wallpaper.. So far the code is this:
`public class MainActivity extends Activity { Bitmap bitmap; int lastImageRef; private static final String ISLOCKED_ARG = "isLocked";
private ViewPager mViewPager;
private static MenuItem menuLockItem;
private WallpaperManager wallpaper;
private static int[] sDrawables = { R.drawable.wallpapertwo, R.drawable.twixkatfirst, R.drawable.wallpaper,
R.drawable.sfondo, R.drawable.wallpapertre};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mViewPager = (HackyViewPager) findViewById(R.id.view_pager);
setContentView(mViewPager);
mViewPager.setAdapter(new SamplePagerAdapter());
if (savedInstanceState != null) {
boolean isLocked = savedInstanceState.getBoolean(ISLOCKED_ARG, false);
((HackyViewPager) mViewPager).setLocked(isLocked);
}
}
static class SamplePagerAdapter extends PagerAdapter {
@Override
public int getCount() {
return sDrawables.length;
}
@Override
public View instantiateItem(ViewGroup container, int position) {
PhotoView photoView = new PhotoView(container.getContext());
photoView.setImageResource(sDrawables[position]);
WallpaperManager wallpaper = WallpaperManager.getInstance(container.getContext());
/*Toast number = Toast.makeText(container.getContext(), "wallpaper number "+position, Toast.LENGTH_LONG);
number.show();*/
// Now just add PhotoView to ViewPager and return it
container.addView(photoView, LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
try
{
wallpaper.setResource(sDrawables[position]);
}
catch (IOException e)
{
}
return photoView;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
}
}`
Now, in the try catch, I can set the wallpaper through position but without tapping any button!! And of course it's not a good way. Any solution? Maybe a button in the actionbar? But I can't find the array position at that point.
You can use FrameLayout:
<FrameLayout...>
<com.ex.paper.HackyViewPager/>
<Button/>
<FrameLayout/>
In onCreate
:
setContentView(your.layout.with.frameLayout);
mViewPager = (HackyViewPager) findViewById(R.id.view_pager);
mButton = (Button) findViewById(R.id.button);
mButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
wallpaper.setResource(sDrawables[mViewPager.getCurrentItem()]);
}
});
}
