好的,我找到了一個解決方案。首先 - 我們需要處理圖像保存意圖的活動,此活動可以啓動服務或其他內容。我做這樣的:
public class ShareActivity extends Activity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle extras = getIntent().getExtras();
String url = extras.getString("url");
String name = extras.getString("name");
String description = extras.getString("description");
SaveImageService.downloadFile(url, name, description);
finish();
}
}
凡SaveImageService
具有處理圖像保存到SD卡 二靜態方法,我們需要添加一些文字在清單:
<activity
android:name=".model.services.ShareActivity"
android:icon="@drawable/download_icon"
android:label="Save">
<intent-filter
android:label="Save"
android:icon="@drawable/download_icon">
<action android:name="com.my_app.random_text.SAVE_IMAGE" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*"/>
</intent-filter>
</activity>
這裏意圖過濾器自定義操作(這很重要),這個自定義操作只是一些字符串,而不是應用程序包或什麼(我只是因爲喜歡它而使用包名)。 接下來,我們需要添加這個活動,分享菜單列表:
這將讓位烏里從ImageView的
在其它應用程序共享
// Returns the URI path to the Bitmap displayed in specified ImageView
static public Uri getLocalBitmapUri(ImageView imageView) {
// Extract Bitmap from ImageView drawable
Drawable drawable = imageView.getDrawable();
Bitmap bmp = null;
if (drawable instanceof BitmapDrawable) {
bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
} else {
return null;
}
// Store image to default external storage directory
Uri bmpUri = null;
try {
File file = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DOWNLOADS), "share_image_" + System.currentTimeMillis() + ".png");
file.getParentFile().mkdirs();
FileOutputStream out = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.JPEG, 80, out);
out.close();
bmpUri = Uri.fromFile(file);
} catch (IOException e) {
e.printStackTrace();
}
return bmpUri;
}
,這將收集可以共享圖像加上我們保存所有的應用程序圖像意圖
public void shareExcludingApp(Context ctx, PhotoView snapImage) {
// Get access to the URI for the bitmap
Uri bmpUri = ShareTool.getLocalBitmapUri(snapImage);
if (bmpUri == null) return;
List<Intent> targetedShareIntents = new ArrayList<>();
//get all apps which can handle such intent
List<ResolveInfo> resInfo = ctx.getPackageManager().queryIntentActivities(createShareIntent(bmpUri), 0);
if (!resInfo.isEmpty()) {
for (ResolveInfo info : resInfo) {
Intent targetedShare = createShareIntent(bmpUri);
//add all apps excluding android system and ourselves
if (!info.activityInfo.packageName.equals(getContext().getPackageName())
&& !info.activityInfo.packageName.contains("com.android")) {
targetedShare.setPackage(info.activityInfo.packageName);
targetedShare.setClassName(
info.activityInfo.packageName,
info.activityInfo.name);
targetedShareIntents.add(targetedShare);
}
}
}
//our local save feature will appear in share menu, intent action SAVE_IMAGE in manifest
Intent targetedShare = new Intent("com.my_app.random_text.SAVE_IMAGE"); //this is that string from manifest!
targetedShare.putExtra(Intent.EXTRA_STREAM, bmpUri);
targetedShare.setType("image/*");
targetedShare.setPackage(getContext().getPackageName());
targetedShare.putExtra("url", iSnapViewPresenter.getSnapUrlForSave());
targetedShare.putExtra("name", iSnapViewPresenter.getSnapNameForSave());
targetedShare.putExtra("description", iSnapViewPresenter.getSnapDescriptionForSave());
targetedShareIntents.add(targetedShare);
//collect all this intents in one list
Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0),
"Share Image");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,
targetedShareIntents.toArray(new Parcelable[targetedShareIntents.size()]));
ctx.startActivity(chooserIntent);
}
該圖標是否也出現在其他應用程序中?你不想在其他活動中表示意思嗎? –
Yeap,它出現在其他應用程序中,即使android畫廊有我的應用程序的共享圖像菜單中的「保存」項目,我想排除我的「保存」活動從其他應用程序共享菜單 –
