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.
My code is:
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");
}
}
});
}
}
xml file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity"
android:orientation="vertical">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/ed"/>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/btn"
android:text="Summit"/>
<ToggleButton
android:id="@+id/toggBtn"
android:layout_below="@+id/text6"

android
togglebutton
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
editString = ed.getText().toString();
if(editString.equals("1")){
toggle.setTextOff("TOGGLE ON");
toggle.setChecked(true);
}
else if(editString.equals("0")){
toggle.setTextOn("TOGGLE OFF");
toggle.setChecked(false);
}
}
<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:
public void onToggleClicked(View view) {
// Is the toggle on?
boolean on = ((ToggleButton) view).isChecked();
if (on) {
// Enable vibrate
} else {
// Disable vibrate
}
}
Try this Toggle Buttons
test_activity.xml
<ToggleButton
android:id="@+id/togglebutton"
android:layout_width="100px"
android:layout_height="50px"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:onClick="toggleclick"/>
Test.java
public class Test extends Activity {
private ToggleButton togglebutton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
togglebutton = (ToggleButton) findViewById(R.id.togglebutton);
}
public void toggleclick(View v){
if(togglebutton.isChecked())
Toast.makeText(TestActivity.this, "ON", Toast.LENGTH_SHORT).show();
else
Toast.makeText(TestActivity.this, "OFF", Toast.LENGTH_SHORT).show();
}
}
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.
I suggest using the radio button provided by Android by default.
Here is how to use it- http://www.mkyong.com/android/android-radio-buttons-example/
and the android documentation is here-
http://developer.android.com/guide/topics/ui/controls/radiobutton.html
Thanks.
You should follow the Google guide;
ToggleButton toggle = (ToggleButton) findViewById(R.id.togglebutton);
toggle.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
// The toggle is enabled
} else {
// The toggle is disabled
}
}
});
You can check the documentation here
Move this
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
editString = ed.getText().toString();
inside onClick
Also you change the state of the toogle button whether its 0
or 1
