这是我想出的解决方案:如果您知道包名称,此功能允许您分享到 instagram、facebook 或任何其他应用程序。如果未安装该应用程序,它会重定向到 Play 商店。如果您将“其他”作为参数发送,您将显示一个也支持图像共享的应用程序列表。
shareImageIntent(mActivity,"image/*", "/storage/emulated/0/Pictures/Instagram/IMG_20150120_095603.jpg", "Instagram Sharing test. #Josh","com.instagram.android"); // parameters - for facebook: "com.facebook.katana" , to display list of other apps you can share to: "others"
public void shareImageIntent(Activity a,String type, String mediaPath, String caption, String app){
Intent intent = mContext.getPackageManager().getLaunchIntentForPackage(app);
if ((intent != null)||(app.equals("others"))){
// Create the new Intent using the 'Send' action.
Intent share = new Intent(Intent.ACTION_SEND);
if(!app.equals("others"))
share.setPackage(app);
// Set the MIME type
share.setType(type);
// Create the URI from the media
File media = new File(mediaPath);
Uri uri = Uri.fromFile(media);
// Add the URI and the caption to the Intent.
share.putExtra(Intent.EXTRA_STREAM, uri);
share.putExtra(Intent.EXTRA_TEXT, caption);
// Broadcast the Intent.
//startActivity(Intent.createChooser(share, "Share to"));
a.startActivity(share);
}
else{
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//intent.setData(Uri.parse("market://details?id="+"com.instagram.android"));
intent.setData(Uri.parse("market://details?id="+app));
a.startActivity(intent);
}
}
