I have a linear layout containing an EditText and an ImageView. I've given the EditText a @null background and have given the LinearLayout a background of:
?android:attr/editTextBackground
to make it look like the whole thing is one widget. When the EditText gets focus/is selected I'd like to update the background drawable of the linear layout to show that the whole thing is selected.
My layout XML for the Linear Layout:
<LinearLayout
android:id="@+id/search_plate"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:attr/editTextBackground">
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="@+id/edit_text"
android:layout_weight="1"
android:background="@null"
android:height="36dp"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="@+id/image_view_close"
android:src="@drawable/ic_clear"
android:focusable="true"
android:background="?android:attr/selectableItemBackground"/>
</LinearLayout>
This is the code I'm using to try and change the background state of the LinearLayout when the EditText is focused:
public class IconEditText extends LinearLayout implements View.OnFocusChangeListener {
private static final String LOG_TAG = "IconEditText";
private View mSearchPlate; // Linear Layout
private EditText mEditTextSearch;
public IconEditText(Context context) {
this(context, null);
}
public IconEditText(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.icon_edit_text, this, true);
mSearchPlate = findViewById(R.id.search_plate);
mEditTextSearch = (EditText) findViewById(R.id.editText);
mEditTextSearch.setOnFocusChangeListener(this);
}
@Override
public void onFocusChange(View view, boolean focused) {
mSearchPlate.getBackground().setState(focused ? FOCUSED_STATE_SET : EMPTY_STATE_SET);
}
}
As well as using FOCUSED_STATE_SET, I've also tried the following:
ENABLED_FOCUSED_SELECTED_STATE_SET
FOCUSED_SELECTED_STATE_SET
ENABLED_SELECTED_STATE_SET
SELECTED_STATE_SET
None of the above seemed to change the background of the LinearLayout to the blue underline. Any help would be appreciated!
