我正在尝试分享图片,但我不确定如何获取此处的图片URI:
imageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/jpeg");
intent.putExtra(Intent.EXTRA_STREAM, [image URI]);
startActivity(Intent.createChooser(intent, "Share image with"));
}
}
下面我列出了上述内容的所有代码。
public class ImagePagerActivity扩展了BaseActivity {
private ViewPager pager;
private DisplayImageOptions options;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ac_image_pager);
Context context = getSupportActionBar().getThemedContext();
ArrayAdapter<CharSequence> list = ArrayAdapter.createFromResource(context, R.array.locations, R.layout.sherlock_spinner_item);
list.setDropDownViewResource(R.layout.sherlock_spinner_dropdown_item);
getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
getSupportActionBar().setListNavigationCallbacks(list, this);
getSupportActionBar().setSelectedNavigationItem(1);
Bundle bundle = getIntent().getExtras();
String[] imageUrls = bundle.getStringArray(Extra.IMAGES);
int pagerPosition = bundle.getInt(Extra.IMAGE_POSITION, 0);
options = new DisplayImageOptions.Builder()
.showImageForEmptyUri(R.drawable.image_for_empty_url)
.cacheOnDisc()
.imageScaleType(ImageScaleType.EXACT)
.build();
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(new ImagePagerAdapter(imageUrls));
pager.setCurrentItem(pagerPosition);
}
@Override
protected void onStop() {
imageLoader.stop();
super.onStop();
}
private class ImagePagerAdapter extends PagerAdapter {
private String[] images;
private LayoutInflater inflater;
ImagePagerAdapter(String[] images) {
this.images = images;
inflater = getLayoutInflater();
}
@Override
public void destroyItem(View container, int position, Object object) {
((ViewPager) container).removeView((View) object);
}
@Override
public void finishUpdate(View container) {
}
@Override
public int getCount() {
return images.length;
}
@Override
public Object instantiateItem(View view, int position) {
final FrameLayout imageLayout = (FrameLayout) inflater.inflate(R.layout.item_pager_image, null);
final ImageView imageView = (ImageView) imageLayout.findViewById(R.id.image);
final ProgressBar spinner = (ProgressBar) imageLayout.findViewById(R.id.loading);
imageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/jpeg");
Uri uri = Uri.fromFile(null);
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(intent, "Share image with"));
}
});
imageLoader.displayImage(images[position], imageView, options, new ImageLoadingListener() {
@Override
public void onLoadingStarted() {
spinner.setVisibility(View.VISIBLE);
}
@Override
public void onLoadingFailed(FailReason failReason) {
String message = null;
switch (failReason) {
case IO_ERROR:
message = "Input/Output error";
break;
case OUT_OF_MEMORY:
message = "Out Of Memory error";
break;
case UNKNOWN:
message = "Unknown error";
break;
}
Toast.makeText(ImagePagerActivity.this, message, Toast.LENGTH_SHORT).show();
spinner.setVisibility(View.GONE);
imageView.setImageResource(android.R.drawable.ic_delete);
}
@Override
public void onLoadingComplete() {
spinner.setVisibility(View.GONE);
Animation anim = AnimationUtils.loadAnimation(ImagePagerActivity.this, R.anim.fade_in);
imageView.setAnimation(anim);
anim.start();
}
@Override
public void onLoadingCancelled() {
// Do nothing
}
});
((ViewPager) view).addView(imageLayout, 0);
return imageLayout;
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view.equals(object);
}
@Override
public void restoreState(Parcelable state, ClassLoader loader) {
}
@Override
public Parcelable saveState() {
return null;
}
@Override
public void startUpdate(View container) {
}
}
@Override
public boolean onNavigationItemSelected(int itemPosition, long itemId) {
if (itemPosition == 0){
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
}
getSupportActionBar().setSelectedNavigationItem(1);
return true;
}
}
如果有人可以提供帮助那就太棒了!

这就是你在drawable中获取图像的URI的方法:
Uri path = Uri.parse("android.resource://your.package.name/" + R.drawable.your_image);
