Changing Text Size

Ever wanted to change text size, font or do HTML inside a text box?

Spannable to the rescue

Detecting done / enter on an EditText

Had some trouble detecting DONE / ACTION_FINISHED / Pressing Enter - They can all fire a bit differently on the emulator and on different phones.

stackoverflow comes to the rescue again!

  myEditText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH ||
                actionId == EditorInfo.IME_ACTION_DONE ||
                event.getAction() == KeyEvent.ACTION_DOWN &&
                event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
            // Do something
        }
        return false;
  });

EditText & removing the popup keyboard

EditText = Like a TextView but designed for entering text


Example code sourced from

The XML file:

  <EditText android:id="@+id/search"
                      android:layout_width="wrap_content"
                      android:layout_height="wrap_content"
                      android:hint="search"
                      android:imeOptions="actionGo" />

This java code will remove the popup keyboard when Done is pressed
Adding the handler to your main Class

        final EditText edittext = (EditText) findViewById(R.id.search);
        edittext.setOnEditorActionListener(new TextView.OnEditorActionListener() {
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                if (actionId == EditorInfo.IME_ACTION_GO) {
                    // hide virtual keyboard
                    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(edittext.getWindowToken(), 0);
                    return true;
                }
                return false;
            }
        });
