我必须将图像与文本共享给所有社交媒体。所以我尝试了以下代码： -
share.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Uri uri = imageUrl;
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/html");
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, (String)
v.getTag(R.string.app_name));
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT,
"Text for post");
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
context.startActivity(Intent.createChooser(shareIntent, "Share Using"));
}
});
它正在运行，现在我可以在gmail中与图像共享文本，就像应用程序一样。但问题是即使我已经安装并更新了所有这些应用程序，我也无法使用此共享意图来获取Facebook，Twitter和Instagram。
我需要获取所有社交媒体应用以进行共享。
使用＆＃34; text / plain＆＃34;作为shareIntent类型Facebook出现但无法共享图像...
有人可以帮我找到答案吗？
提前致谢。

试试这个为我工作，
public partial class Form1 : Form
{
List<double> values_1 = new List<double>();
List<double> values_2 = new List<double>();
public Form1()
{
InitializeComponent();
make_values();
for (int i = 0; i < values_1.Count; i++)
{
chart1.Series[0].Points.AddY(values_1[i]);
}
for (int i = 0; i < values_2.Count; i++)
{
chart1.Series[1].Points.AddY(values_2[i]);
}
// set the colour of grid to corresponding line
chart1.ChartAreas[0].AxisY2.MajorGrid.LineColor = chart1.Series[1].Color;
}
private void Form1_Load(object sender, EventArgs e)
{
}
public void make_values()
{
for (int i = 0; i < 600; i++)
{
values_1.Add(Math.Sin(i / 60.0));
values_2.Add(Math.Cos(i / 60.0));
}
}
}
在void share(String nameApp, Uri imagePath) {
boolean isAppExist = false;
try {
List<Intent> targetedShareIntents = new ArrayList<Intent>();
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/*");
List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(share, 0);
if (!resInfo.isEmpty()) {
for (ResolveInfo info : resInfo) {
Intent targetedShare = new Intent(Intent.ACTION_SEND);
targetedShare.setType("image/*"); // put here your mime type
if (info.activityInfo.packageName.toLowerCase().contains(nameApp) || info.activityInfo.name.toLowerCase().contains(nameApp)) {
targetedShare.putExtra(Intent.EXTRA_SUBJECT, getString(R.string.share_title));
targetedShare.putExtra(Intent.EXTRA_TEXT, shareMessage);
if (imagePath != null)
targetedShare.putExtra(Intent.EXTRA_STREAM, imagePath);
targetedShare.setPackage(info.activityInfo.packageName);
targetedShareIntents.add(targetedShare);
isAppExist = true;
}
}
Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select app to share");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
startActivityForResult(chooserIntent, REQUEST_SHARE);
}
} catch (Exception e) {
Utils.setLog("Exception while sending image on" + nameApp + " " + e.getMessage());
}
if (!isAppExist) {
Dialogs.showAlert(this, null, getString(R.string.share_no_application_found), true, false);
}
}
中，您必须传递您必须在其中发布图片的应用程序名称。在你的情况下通过nameApp。

尝试以下代码：
public void share(final String url, final String text) {
new Thread(new Runnable() {
@Override
public void run() {
try {
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
share.putExtra(
Intent.EXTRA_TEXT,
"Sharing from "
+ context.getString(R.string.app_name)
+ "\n" + text);
if (url != null) {
Bitmap bmp = null;
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
try {
byte[] chunk = new byte[4096];
int bytesRead;
InputStream stream = new URL(url).openStream();
while ((bytesRead = stream.read(chunk)) > 0) {
outputStream.write(chunk, 0, bytesRead);
}
outputStream.toByteArray();
bmp = BitmapFactory.decodeByteArray(
outputStream.toByteArray(), 0,
outputStream.toByteArray().length);
} catch (IOException e) {
e.printStackTrace();
Log.v("Error", e.toString());
}
String filename = Environment.getExternalStorageDirectory().getAbsoluteFile() + File.separator + File.separator
+ Utils.getCurrentTimeInFormate() + ".png";
Log.e("BITMAP", filename);
FileOutputStream out = new FileOutputStream(filename);
bmp.compress(Bitmap.CompressFormat.PNG, 50, out);
Bitmap icon = bmp;
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, "title");
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
Uri uri = context.getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
OutputStream outstream;
try {
outstream = context.getContentResolver()
.openOutputStream(uri);
icon.compress(Bitmap.CompressFormat.PNG, 60, outstream);
outstream.close();
} catch (Exception e) {
System.err.println(e.toString());
}
share.putExtra(Intent.EXTRA_STREAM, uri);
}
context.startActivity(Intent.createChooser(share, "Share"));
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
}
