android7.0实现分享图片到朋友圈功能

时间:2021-05-20

本文实例为大家分享了android实现分享图片到朋友圈功能的具体代码,供大家参考,具体内容如下

在Android7.0中,系统对scheme为file://的uri进行了限制,所以通过这种uri来进行分享的一些接口就不能用了,比如使用代码来调用分享朋友圈的接口。

此时就得使用其他的URI scheme来代替 file://,比如MediaStore的 content://。直接上代码:

private static boolean checkInstallation(Context context, String packageName) { try { context.getPackageManager().getPackageInfo(packageName, PackageManager.GET_ACTIVITIES); return true; } catch (PackageManager.NameNotFoundException e) { return false; } } public static void shareToWeChat(View view, Context context) { // TODO: 2015/12/13 将需要分享到微信的图片准备好 try { if (!checkInstallation(context, "com.tencent.mm")) { SnackBarUtil.show(view, R.string.share_no_wechat); return; } Intent intent = new Intent(); //分享精确到微信的页面,朋友圈页面,或者选择好友分享页面 ComponentName comp = new ComponentName("com.tencent.mm", "com.tencent.mm.ui.tools.ShareToTimeLineUI"); intent.setComponent(comp); intent.setAction(Intent.ACTION_SEND_MULTIPLE); intent.setType("image/*");// intent.setType("text/plain"); //添加Uri图片地址// String msg=String.format(getString(R.string.share_content), getString(R.string.app_name), getLatestWeekStatistics() + ""); String msg = context.getString(R.string.share_content); intent.putExtra("Kdescription", msg); ArrayList<Uri> imageUris = new ArrayList<Uri>(); // TODO: 2016/3/8 根据不同图片来设置分享 File dir = context.getExternalFilesDir(null); if (dir == null || dir.getAbsolutePath().equals("")) { dir = new File(Environment.getExternalStorageDirectory().getAbsolutePath()); } File pic = new File(dir, "bigbang.jpg"); pic.deleteOnExit(); BitmapDrawable bitmapDrawable; if (Build.VERSION.SDK_INT < 22) { bitmapDrawable = (BitmapDrawable) context.getResources().getDrawable(R.mipmap.bannar); } else { bitmapDrawable = (BitmapDrawable) context.getDrawable(R.mipmap.bannar); } try { bitmapDrawable.getBitmap().compress(Bitmap.CompressFormat.JPEG, 75, new FileOutputStream(pic)); } catch (FileNotFoundException e) { e.printStackTrace(); } if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) { imageUris.add(Uri.fromFile(pic)); }else { //修复微信在7.0崩溃的问题 Uri uri =Uri.parse(android.provider.MediaStore.Images.Media.insertImage(context.getContentResolver(), pic.getAbsolutePath(), "bigbang.jpg", null)); imageUris.add(uri); } intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris); ((Activity) context).startActivityForResult(intent, 1000); }catch (Throwable e){ SnackBarUtil.show(view,R.string.share_error); }

还有一种方式,就是FileProvider来分享文件,操作起来稍微复杂一点,大概代码如下(代码功能是拍照的):

String mCurrentPhotoPath;private File createImageFile() throws IOException { // Create an image file name String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); String imageFileName = "JPEG_" + timeStamp + "_"; File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES); File image = File.createTempFile( imageFileName, ".jpg", storageDir ); // Save a file: path for use with ACTION_VIEW intents mCurrentPhotoPath = "file:" + image.getAbsolutePath(); return image;}static final int REQUEST_TAKE_PHOTO = 1;private void dispatchTakePictureIntent() { Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); // Ensure that there's a camera activity to handle the intent if (takePictureIntent.resolveActivity(getPackageManager()) != null) { // Create the File where the photo should go File photoFile = null; try { photoFile = createImageFile(); } catch (IOException ex) { // Error occurred while creating the File ... } // Continue only if the File was successfully created if (photoFile != null) { Uri photoURI = FileProvider.getUriForFile(this, "com.example.android.fileprovider", photoFile); takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI); startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO); } }}

还要在manifest中声明这个FileProvider

<application> ... <provider android:name="android.support.v4.content.FileProvider" android:authorities="com.example.android.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths"></meta-data> </provider> ...</application>

在res/xml/文件夹下新建文件file_paths.xml:

<?xml version="1.0" encoding="utf-8"?><paths xmlns:android="http://schemas.android.com/apk/res/android"> <external-path name="my_images" path="Android/data/com.example.package.name/files/Pictures" /></paths>
