Example on ToggleButton
提问by Durga
I am developing an application using a toggle button, I entered 1 or 0 in EditText. When button is clicked, the toggle button has to change if I enter 1 the toggle button shows TOGGLE ON, if I enter 0 the toggle button has to show TOGGLE OFF. I am unable to get toggle values when the button is clicked.
我正在使用切换按钮开发应用程序，我在EditText. 单击按钮时，切换按钮必须更改，如果我输入 1 切换按钮显示TOGGLE ON，如果我输入 0 切换按钮必须显示TOGGLE OFF。单击按钮时，我无法获得切换值。
My code is:
我的代码是：
public class MainActivity extends Activity {
String editString="";
Button btn;
EditText ed;
ToggleButton toggle;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button)findViewById(R.id.btn);
ed = (EditText)findViewById(R.id.ed);
toggle = (ToggleButton)findViewById(R.id.toggBtn);
editString = ed.getText().toString();
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
toggle.toggle();
if(editString.equals("1")){
toggle.setTextOff("TOGGLE ON");
}
else if(editString.equals("0")){
toggle.setTextOn("TOGGLE OFF");
}
}
});
}

<ToggleButton
android:id="@+id/togglebutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOn="Vibrate on"
android:textOff="Vibrate off"
android:onClick="onToggleClicked"/>
Within the Activity that hosts this layout, the following method handles the click event:
在承载此布局的 Activity 中，以下方法处理单击事件：
public void onToggleClicked(View view) {
// Is the toggle on?
boolean on = ((ToggleButton) view).isChecked();
if (on) {
// Enable vibrate
} else {
// Disable vibrate
}
}

Just remove the line toggle.toggle();from your click listener toggle()method will always reset your toggle button value.
只需toggle.toggle();从单击侦听器toggle()方法中删除该行将始终重置您的切换按钮值。
And as you are trying to take the value of EditTextin string variable which always remains same as you are getting value in onCreate()so better directly use the EditTextto get the value of it in your onClicklistener.
并且当您尝试获取EditTextin 字符串变量的值时，该值始终与获取值相同，onCreate()因此更好地直接使用EditText来获取它在onClick侦听器中的值。
Just change your code as below its working fine now.
只需更改您的代码，如下所示，现在可以正常工作了。
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//toggle.toggle();
if ( ed.getText().toString().equalsIgnoreCase("1")) {
toggle.setTextOff("TOGGLE ON");
toggle.setChecked(true);
} else if ( ed.getText().toString().equalsIgnoreCase("0")) {
toggle.setTextOn("TOGGLE OFF");
toggle.setChecked(false);
}
}
});

ToggleButton toggle = (ToggleButton) findViewById(R.id.togglebutton);
toggle.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

// The toggle is enabled
} else {
// The toggle is disabled

回答by Neeraj Shukla
I think what are attempting is semantically same as a radio button when 1 is when one of the options is selected and 0 is the other option.
当 1 是选择其中一个选项而 0 是另一个选项时，我认为尝试的内容在语义上与单选按钮相同。
I suggest using the radio button provided by Android by default.
我建议默认使用 Android 提供的单选按钮。
