customize select texts actions in android?

Question

please help me how can I do this: I have textView in my project and I want do this:

select text
do some actions like copy,save,... on texts

I find out this code for selecting part:

    text= (TextView) findViewById(R.id.speech);
    registerForContextMenu(text);
    text.setTextIsSelectable(true);

and the default Sellection texs with copy and select all actions are shown.

now my question is that how can I customize it and add other actions to it?

this is my class:

    public class SellectedTexts extends AppCompatActivity implements ActionMode.Callback {
    @Override
    public boolean onCreateActionMode(ActionMode mode, Menu menu) {
       // Log.d(Log, "onCreateActionMode");
        MenuInflater inflater = mode.getMenuInflater();
        inflater.inflate(R.menu.text_select, menu);
            return true;
        }

     @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            return false;
        }

    @Override
    public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
      //  Log.d(Log, String.format("onActionItemClicked item=%s/%d", item.toString(), item.getItemId()));

        switch(item.getItemId()) {

            case R.id.save:
                File outputTXT =new File(Environment.getExternalStorageDirectory(), "App Folder");
                outputTXT.mkdir();


                if (!outputTXT.exists() && !outputTXT.mkdirs()) { //Can't make path to save pic.


                    //Log.d(DEBUG_TAG, "Can't create directory to save image");
                    Toast.makeText(this, "File can't save.",Toast.LENGTH_LONG).show();
                }


                Calendar calender =Calendar.getInstance();
                SimpleDateFormat simpleDateFormat =new SimpleDateFormat("yyyymmdd_hhmmss");
                String fileName =outputTXT.getPath() + File.separator + simpleDateFormat.format(calender.getTime())+" .txt";
                File pictureFile =new File(fileName);

                try {
                    FileOutputStream fos = new FileOutputStream(pictureFile);
                    fos.write(MainActivity.speech_text.getText().toString().getBytes());
                    fos.close();
                    Toast.makeText(this, "File save in ExternalCard/Type-Yar folder.",Toast.LENGTH_LONG).show();
                } catch (Exception error) {  //Can't save image.

                  //  Log.d(DEBUG_TAG, "File not saved: " + error.getMessage());
                    Toast.makeText(this, "File can't save.", Toast.LENGTH_LONG).show();
                }
                mode.finish();// Finish and close the ActionMode
                return true;
        }
        return true;
    }

    @Override
    public void onDestroyActionMode(ActionMode mode) {

    }


}

Hope this helps

Check this answer https://stackoverflow.com/a/13004720/2826147, it has very good explaination with example as well as readout comment too.

TextView has a method setCustomSelectionActionModeCallback() which should be used instead of startActionMode(). Using this enables customisation of the menu used by TextView for text selection.

Sample code:

bodyView.setCustomSelectionActionModeCallback(new StyleCallback());

If you dont have space than you can remove any pre-populated menu items then add your own.

public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
        Log.e("", String.format("onActionItemClicked item=%s/%d", item.toString(), item.getItemId()));
        CharacterStyle cs;
        TextView bodyView = null;
        int start = bodyView.getSelectionStart();
        int end = bodyView.getSelectionEnd();
        SpannableStringBuilder ssb = new SpannableStringBuilder(bodyView.getText());

        /*Toast.makeText(getActivity(), (String)data.result,
                Toast.LENGTH_LONG).show();*/

        Toast.makeText(this, " toast shown ", Toast.LENGTH_LONG).show();


        switch (item.getItemId()) {

            case R.id.bold:
                cs = new StyleSpan(Typeface.BOLD);
                ssb.setSpan(cs, start, end, 1);
                bodyView.setText(ssb);
                return true;

            case R.id.italic:
                cs = new StyleSpan(Typeface.ITALIC);
                ssb.setSpan(cs, start, end, 1);
                bodyView.setText(ssb);
                return true;

            case R.id.underline:
                cs = new UnderlineSpan();
                ssb.setSpan(cs, start, end, 1);
                bodyView.setText(ssb);
                return true;
        }
        return false;
    }

thanks. if i want to use toast in this class, how can i define it? – Apr 29 '16 at 10:24
make your class **extend AppCompatActivity** and than **Toast.makeText(this, " toast shown ", Toast.LENGTH_LONG).show();** – Amit Vaghela Apr 29 '16 at 10:40
i do so, but my app has stoped. – Apr 29 '16 at 11:35
at android.widget.Toast.(Toast.java:132) at android.widget.Toast.makeText(Toast.java:434) at .SellectedTexts.onActionItemClicked(SellectedTexts.java:57) – Apr 29 '16 at 11:49
i try "this" , "context" but they are not work correctly. also i do "getActivity" but it doesn't recognize in android studio. – Apr 29 '16 at 17:47
My friend you need to extend your class to appcompatactivity than you will be able to use toast – Amit Vaghela Apr 29 '16 at 17:49
have you defined text in **string.xml** file ? that you are using in Toast ? – Amit Vaghela Apr 30 '16 at 09:01
i use char instead of string, so what is theproblem? – Apr 30 '16 at 10:04
Please do some other tutorials of basic android before doing this. – Amit Vaghela Apr 30 '16 at 10:17
