It is possible to create a ToggleButton without text?

i want to create a android default ToggleButton like this: enter image description here

but i want to create it without TEXT

I tryed with this code: 

ToggleButton tb = new ToggleButton(map);
tb.setText(null);
tb.setTextOn(null);
tb.setTextOff(null);

But it is leaving a empty space in the top of the horizontal green bar.

I dont want that empty space, i only want the horizontal green bar.

How to achieve it?

Layout File.xml

       <ToggleButton
    android:id="@+id/toggle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="8dp"
    android:background="@drawable/check"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

In main activity.java

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final ToggleButton mic = (ToggleButton)findViewById(R.id.toggle);
    mic.setTextOff(null);
    mic.setTextOn(null);
    mic.setText(null);

check.xml which is used by layout.xml

<?xml version="1.0" encoding="utf-8"?>


    <item android:drawable="@drawable/mic_on"
        android:state_checked="true">

    </item>
    <!-- When not selected, use white-->
    <item android:drawable="@drawable/mic_off"
        android:state_checked="false">

    </item>

These lines are those what you are looking for

    mic.setTextOff(null);
    mic.setTextOn(null);
    mic.setText(null);

Fill style XML like this.. the magic is text color as transparent...

android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textOff="blabla"
android:textOn="blablabla"
android:textColor="@android:color/transparent"
android:background="@drawable/boutmediumrouge"

/>

It's much more hassle-free to use a CheckBox instead of the ToggleButton. They have the same states and thus achieve the same functionality, but you can easily change the CheckBox appearence by defining its <android:button="@drawable/..."> attribute.

Using 

<ToggleButton
    ...
    android:textOff="@null"
    android:textOn="@null"
    android:textSize="0dp" />

will not only make the text go away, but also get rid of the empty space where it would otherwise be shown.

The empty space in the top is caused by the 2 Ninepatch (btn_toggle_off.9.png and btn_toggle_on.9.png ) used in default toggleButton style.

To perfectly center the horizontal bar, you must create a new style for ToggleButton that will use two new ninepatch derived form original.

Edit: Method requiring minimal XML:

  • create your two ninepatches for your togglebutton, name it: my_btn_toggle_on and my_btn_toggle_off

  • in drawable folder, create my_btn_toggle.xml:

    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false" android:drawable="@drawable/my_btn_toggle_off" />
    <item android:state_checked="true" android:drawable="@drawable/my_btn_toggle_on" />
</selector>

  • in your code, add tb.setBackgroundResource(R.drawable.my_btn_toggle) :

    ToggleButton tb = new ToggleButton(map);
tb.setText(null);
tb.setTextOn(null);
tb.setTextOff(null);
tb.setBackgroundResource(R.drawable.my_btn_toggle)

Just set following things:

<ToggleButton android:id="@+id/tbtn1" 
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:background="@drawable/bg_check"
 android:textOn="" 
 android:textOff="" 
 android:text="" />

And, the style xml, if you need...

<selector xmlns:android="http://schemas.android.com/apk/res/android">

  <item android:state_checked="true" 
android:drawable="@drawable/bg_check_on" /> <!-- pressed -->

  <item android:drawable="@drawable/bg_check_off" /> <!-- default/unchecked -->
</selector>

Hope it helps~

Not the most elegant solution but you could try tb.setTextSize(0); if you're just trying to hide the extra space on top. May need to set the textOn/textOff to an empty string: tb.setTextOn("");

EDIT: I better option would be to create your own custom button by extending Button, hold the state (see this SO post for pressed/unpressed states: Pressed android button state) and find the assets to set as the appropriate state...
