I've been using 2-way databinding for a basic application, it was going
pretty well, until i start with custom views and attrs.
I want to create a custom view, with has a TextView and a EditText, and use
it inside another layout:
<TextView
android:text="Holder"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/tvTitle"
android:layout_weight="1" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="none"
android:text="Name"
android:ems="10"
android:id="@+id/etAnwser"
android:layout_weight="1" />
And i have the custom attr for it
<resources>
<declare-styleable name="form_item">
<attr name="tvTitle" format="string" />
<attr name="anwserHint" format="string" />
<attr name="anwserText" format="string" />
<attr name="android:enabled" />
</declare-styleable>
In the fragment i do the following:
<rhcloud.com.financialcontrol.tabutil.FormItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:enabled="@{state.get()}"
form_item:anwserText='@={expense.description}'
form_item:tvTitle="Description:" />
It works nice has 1-way databind, but whatever i change the text, he don't
send me the callback in class
@InverseBindingMethods(value = {
@InverseBindingMethod(type = FormItem.class, attribute = "anwserText"),
})
public class FormItem extends LinearLayout {
private TextView tvTitle;
private EditText etAnwser;
public FormItem(@NonNull Context context) {
super(context);
LayoutInflater inflater = (LayoutInflater)
getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.form_item, this);
tvTitle = (TextView) findViewById(R.id.tvTitle);
etAnwser = (EditText) findViewById(R.id.etAnwser);
}
public FormItem(@NonNull Context context, @NonNull String title) {
this(context);
setTvTitle(title);
}
public FormItem(@NonNull Context context, @NonNull String title, @NonNull
String hint) {
this(context, title);
setAnwserHint(hint);
}
public FormItem(@NonNull Context context, @NonNull String title, @NonNull
String hint, @NonNull String anwserText) {
this(context, title, hint);
setAnwserHint(anwserText);
}
public FormItem(@NonNull Context context, @NonNull AttributeSet attrs) {
super(context, attrs);
LayoutInflater inflater = (LayoutInflater)
getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.form_item, this);
tvTitle = (TextView) findViewById(R.id.tvTitle);
etAnwser = (EditText) findViewById(R.id.etAnwser);
TypedArray a = context.getTheme().obtainStyledAttributes(
attrs,
R.styleable.form_item,
0, 0);
try {
setTvTitle(a.getString(R.styleable.form_item_tvTitle));
setAnwserHint(a.getString(R.styleable.form_item_anwserHint));
setAnwserText(a.getString(R.styleable.form_item_anwserText));
String isEnabled =
a.getString(R.styleable.form_item_android_enabled);
if (isEnabled != null) {
setEnable(Boolean.parseBoolean(isEnabled));
}
} finally {
a.recycle();
}
}
public void setTvTitle(String title) {
tvTitle.setText(title);
}
public String getTvTitle() {
return tvTitle.getText().toString();
}
public void setAnwserHint(String hint) {
etAnwser.setHint(hint);
}
public String getAnwserHint() {
return etAnwser.getHint().toString();
}
public void setEnable(boolean isEnable) {
tvTitle.setEnabled(isEnable);
etAnwser.setEnabled(isEnable);
}
public void setAnwserText(String anwserText) {
etAnwser.setText(anwserText);
}
public String getAnwserText() {
return etAnwser.getText().toString();
}
@InverseBindingAdapter(attribute = "form_item:anwserText")
public static String setOnAnwserTextAttrChanged(final String value){
Log.d("Test","Calling InverseBindingAdapter: " + value);
return value;
}
@BindingAdapter(value = {"anwserTextAttrChanged"},
requireAll = false)
public static void setOnAnwserTextAttrChanged(final FormItem view,final
InverseBindingListener anwserTextAttrChanged){
Log.d("Test","Calling BindingAdapter: " + view.getAnwserText());
if(anwserTextAttrChanged == null){
}else{
Log.d("Test","Calling here");
anwserTextAttrChanged.onChange();
}
}
@BindingAdapter(value = {"android:enabled"})
public static void customEnable(FormItem formItem, boolean isEnable) {
formItem.setEnable(isEnable);
}
}
Does anyone know how to make it work properly?
