单击图像时如何完整显示图像？

试试这个

Uri uri; Intent intent = new Intent(Intent.ACTION_VIEW);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { uri = Uri.parse("image_route"); } else { uri = Uri.fromFile(new File("image_route")); } String mime = "/"; MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton(); if (mimeTypeMap.hasExtension( mimeTypeMap.getFileExtensionFromUrl(uri.toString()))) mime = mimeTypeMap.getMimeTypeFromExtension( mimeTypeMap.getFileExtensionFromUrl(uri.toString())); intent.setDataAndType(uri, mime);
