Mixing
Checkbox checked or not cannot be logged
-1
I am an android learner, I have a task from my course to write into the log when a checkbox is clicked.
My XML is:
<CheckBox
android:id="@+id/whippedCreamCheckBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Whipped Cream"
android:textSize="16sp"
android:paddingLeft ="24dp"
android:buttonTint="#008000"
android:textAppearance="?android:textAppearanceMedium" />
And corresponding java code is
public void indicateBoxChecked(View v) {
CheckBox whippedCreamCheckBox = findViewById(R.id.whippedCreamCheckBox);
boolean checked = whippedCreamCheckBox.isChecked();
Log.v(TAG, "Checkbox value is " + checked );
}
The remaining code builds, runs and functions without errors. However, in the log I cannot see the desired output. But I see
Not supplying enough data to HAL, expected position 4798584 , only
wrote 4798080

Add this attribute to the CheckBox:
android:onClick="indicateBoxChecked"
and change your code to this (it is inside your activity class isn't it?):
public void indicateBoxChecked(View v) {
CheckBox whippedCreamCheckBox = (CheckBox) v;
boolean checked = whippedCreamCheckBox.isChecked();
Log.v(TAG, "Checkbox value is " + checked );
}
now whenever you click the CheckBox, the method indicateBoxChecked() will be executed.
I guess the variable TAG has been initialized.
