Java Code Examples for com.android.internal.util.XmlUtils#convertValueToBoolean()

/**
 * Retrieve the boolean value for the attribute at <var>index</var>.

 * If the attribute is an integer value, this method will return whether
 * it is equal to zero. If the attribute is not a boolean or integer value,
 * this method will attempt to coerce it to an integer using
 * {@link Integer#decode(String)} and return whether it is equal to zero.
 *
 * @param index Index of attribute to retrieve.
 * @param defValue Value to return if the attribute is not defined or
 *                 cannot be coerced to an integer.
 *
 * @return Boolean value of the attribute, or defValue if the attribute was
 *         not defined or could not be coerced to an integer.
 * @throws RuntimeException if the TypedArray has already been recycled.
