Create Different Inversebindingadapter For Short And Integer Values On Android:text Of Edittext

I create these methods for custom data binding @BindingAdapter('android:text') public static void setShortText(TextView view, short value) { view.setText(String.valueOf(value))

Solution 1:

I find a solution, but really not satisfy myself. I change getIntText return value from Integer to int and problem is solved. if someone find other better solution please let me know.

@InverseBindingAdapter(attribute = "android:text")
publicstatic int getIntText(TextView view) {
    try {
        returnInteger.parseInt(view.getText().toString());
    } catch (NumberFormatException e) {
        return -1;
    }
}

Solution 2:

For this solution to work correctly, it is necessary to make it possible to receive a null value, and check if the new value of TextView is different from the previous value. If I contract, the Binding methods will be executed forever.

Here is my solution:

@BindingAdapter("android:text")funsetBindShortText(view: TextView, value: Short?) {
    value?.let {
        if (!it.toString().contentEquals(view.text))
            view.text = it.toString()
    }
}
@InverseBindingAdapter(attribute = "android:text")fungetBindShortText(view: TextView): Short? {
    returntry {
        view.text.toString().toShort()
    } catch (e: java.lang.NumberFormatException) {
        null
    }
}


@BindingAdapter("android:text")funsetBindIntText(view: TextView, value: Int?) {
    value?.let {
        if (!it.toString().contentEquals(view.text))
            view.text = it.toString()
    }
}
@InverseBindingAdapter(attribute = "android:text")fungetBindIntText(view: TextView): Int? {
    returntry {
        view.text.toString().toInt()
    } catch (e: NumberFormatException) {
        null
    }
}
