Answer 1

private void shareImage(Uri imagePath) {
    Intent sharingIntent = new Intent(Intent.ACTION_SEND);
    sharingIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    sharingIntent.setType("image/*");
    sharingIntent.putExtra(Intent.EXTRA_STREAM, imagePath);
    //sharingIntent.setPackage("com.whatsapp"); for whatsapp only
    startActivity(Intent.createChooser(sharingIntent, "Share Image Using"));// for all generic options
}

最后在你的清单中添加此内容

        <activity
        android:name=".YourActivity"
        android:icon="@drawable/share_this"
        android:label="@string/shared_activity" >
        <intent-filter>
            <action android:name="android.intent.action.SEND" /> <!-- Send 
         action required to display activity in share list -->
            <category android:name="android.intent.category.DEFAULT" /> <!-- 
          Make activity default to launch -->
            <!-- Mime type i.e. what can be shared with this activity only image and text -->
            <data android:mimeType="image/*" />
            <data android:mimeType="text/*" />
        </intent-filter>
    </activity>

这将是owrk

Answer 2

ArrayList<Uri> uriArrayList = new ArrayList<>();
uriArrayList.add(getUriFromFile(your file path))
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND_MULTIPLE);

intent.setType("image/*");
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, myFilesUriList);
startActivity(intent);


public Uri getUriFromFile(File theSrcPath) {
        Uri requirdUri = null;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            requirdUri = FileProvider.getUriForFile(theCtx,
                    theCtx.getApplicationContext().getPackageName() + PROVIDER_FILE_EXTENSION,
                    theSrcPath);
        } else {
            requirdUri = Uri.fromFile(theSrcPath);
        }

}
