我想像这样创建一个android默认值ToggleButton：
but i want to create it without TEXT
但我想在没有文本的情况下创建它
I tryed with this code:
我尝试使用此代码：
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.
但它在水平绿色条的顶部留下了一个空白空间。
I dont want that empty space, i only want the horizontal green bar.
我不想要那个空的空间，我只想要水平的绿色条。
How to achieve it?
如何实现？

谢谢

The empty space in the top is caused by the 2 Ninepatch (btn_toggle_off.9.pngand btn_toggle_on.9.png) used in default toggleButton style.
顶部的空白是由默认切换按钮样式中使用的 2 Ninepatch (btn_toggle_off.9.png和btn_toggle_on.9.png)引起的。
To perfectly center the horizontal bar, you must create a new style for ToggleButton that will use two new ninepatch derived form original.
为了使水平条完美居中，您必须为 ToggleButton 创建一个新样式，该样式将使用两个新的 Ninepatch 派生形式原始。
Edit: Method requiring minimal XML:
编辑：需要最少 XML 的方法：
create your two ninepatches for your togglebutton, name it:
my_btn_toggle_on andmy_btn_toggle_offin 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)
为切换按钮创建两个九块，命名为：
my_btn_toggle_on 和my_btn_toggle_off在 drawable 文件夹中，创建
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>在您的代码中，添加
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:
只需设置以下内容：
<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...
而且，样式 xml，如果您需要...
<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~
希望有帮助~

Using
使用
<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.
不仅会使文本消失，还会消除原本会显示的空白区域。

It's much more hassle-free to use a CheckBoxinstead of the ToggleButton. They have the same states and thus achieve the same functionality, but you can easily change the CheckBoxappearence by defining its <android:button="@drawable/...">attribute.
使用 aCheckBox而不是ToggleButton. 它们具有相同的状态并因此实现相同的功能，但您可以CheckBox通过定义其<android:button="@drawable/...">属性轻松更改外观。

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
layout.xml 使用的 check.xml
<?xml version="1.0" encoding="utf-8"?>

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("");
不是最优雅的解决方案，但tb.setTextSize(0);如果您只是想隐藏顶部的额外空间，您可以尝试。可能需要将 textOn/textOff 设置为空字符串：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...
编辑：我更好的选择是通过extending创建您自己的自定义按钮Button，保持状态（请参阅此 SO 帖子以了解按下/未按下状态：按下 android 按钮状态）并找到要设置为适当状态的资产...
