How to share dynamic text in android ShareActionProvider

Question

I want to share dynamic text using ShareActionProvider. I'm using this code in my Fragment:

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.detailfragment, menu);
    MenuItem menuItem = menu.findItem(R.id.action_share);

    private ShareActionProvider mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);

    if (mForecast != null) {
            mShareActionProvider.setShareIntent(createShareForecastIntent());
        }
}  

private Intent createShareForecastIntent() {
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    shareIntent.setType("text/plain");
    shareIntent.putExtra(Intent.EXTRA_TEXT, editText.getText().toString());
    return shareIntent;
}

This will share the text that was before entering the Activity, even if I'll change it in EditText before pressing share button. And this code works as I want, but I don't want to make separate button for sharing:

@Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.button:
                Intent myIntent = new Intent();
                myIntent.setAction(Intent.ACTION_SEND);
                myIntent.putExtra(Intent.EXTRA_TEXT, editText.getText().toString());
                myIntent.setType("text/plain");
                startActivity(myIntent);
                break;
        default:
                //
    }
}

I'm using:

minSdkVersion 14
targetSdkVersion 19

Try setting the Share Intent in your onOptionsItemSelected method — Ariel Carbonaro, Aug 29 '14 at 20:19

Update your shareIntent when the text changes, using a TextWatcher. This sample project has an activity that does just what you describe:

import android.view.Menu;
import android.widget.EditText;
import android.widget.ShareActionProvider;

public class MainActivity extends Activity implements
    ShareActionProvider.OnShareTargetSelectedListener, TextWatcher {
  private ShareActionProvider share=null;
  private Intent shareIntent=new Intent(Intent.ACTION_SEND);
  private EditText editor=null;

  @Override
  public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.activity_main);

    shareIntent.setType("text/plain");
    editor=(EditText)findViewById(R.id.editor);
    editor.addTextChangedListener(this);
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.actions, menu);

    share=
        (ShareActionProvider)menu.findItem(R.id.share)
                                 .getActionProvider();
    share.setOnShareTargetSelectedListener(this);

    return(super.onCreateOptionsMenu(menu));
  }

  @Override
  public boolean onShareTargetSelected(ShareActionProvider source,
                                       Intent intent) {
    Toast.makeText(this, intent.getComponent().toString(),
                   Toast.LENGTH_LONG).show();

    return(false);
  }

  @Override
  public void afterTextChanged(Editable s) {
    shareIntent.putExtra(Intent.EXTRA_TEXT, s.toString());
    share.setShareIntent(shareIntent);
  }

  @Override
  public void beforeTextChanged(CharSequence s, int start, int count,
                                int after) {
    // ignored
  }

  @Override
  public void onTextChanged(CharSequence s, int start, int before,
                            int count) {
    // ignored
  }
}

Note that I am not sure if the setShareIntent() call is needed on every text change; I haven't tried removing that and just updating the extra.

I need to share text from 2 different textviews concated to one string and I set text with the setText method, but as I understood TextWatcher doesn't accept it as changed, is there else solutions? — Nikita Axyonov, Sep 07 '14 at 21:50
