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:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
/>
Answer
Just remove the line toggle.toggle(); from your click listener toggle() method will always reset your toggle button value.
And as you are trying to take the value of EditText in string variable which always remains same as you are getting value in onCreate() so better directly use the EditText to get the value of it in your onClick listener.
Just change your code as below its working fine now.
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);
}
}
});
