my problem : when I click on ListViews' item , it changes its' state in such order: if unchecked - Unchecked, Checked,Unchecked,Checked while I expect it simply become checked without any flashing and winkling
if checked : Checked - Unchecked (no problem)
this bug appears ONLY on pre-HoneyComb devices , on ICS everything is Ok
I think this bug refers to built-in mechanisms of Android . If so, is there any solution?
What I have :
1) Listview ( multiChoice = true
)
2) Selector :
<item android:drawable="@color/main_listview_item_pressed_longpressed"
android:state_pressed="true" />
<item android:drawable="@color/main_listview_item_pressed_longpressed"
android:state_checked="true" />
which is applied to ListViews' item layout
3) Item layout:
<com.sasha.medclock2.CheckedLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:paddingLeft="5dip"
android:background="@drawable/list_item_selector"
android:id="@+id/linerar_layout_checkable"
>
<TextView
android:id="@+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@drawable/textview_selector"
/>
<TextView
android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@drawable/textview_selector"
/>
<TextView
android:id="@+id/text3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@drawable/textview_selector"
/>
<TextView
android:id="@+id/text4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@drawable/textview_selector"
/>
</com.sasha.medclock2.CheckedLinearLayout>
4) CheckedLinearLayout :
public class CheckedLinearLayout extends LinearLayout implements Checkable {
private final static String TAG = "CheckableLinearLayout";
private static final int[] CHECKED_STATE_SET = {
android.R.attr.state_checked
};
private boolean checked = false;
public CheckedLinearLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CheckedLinearLayout(Context context) {
super(context);
}
@Override
public boolean isChecked() {
return checked;
}
@Override
public void setChecked(boolean checked) {
this.checked = checked;
refreshDrawableState();
//Propagate to childs
final int count = getChildCount();
for (int i = 0; i < count; i++) {
final View child = getChildAt(i);
if(child instanceof Checkable) {
((Checkable)child).setChecked(checked);
}
}
}
@Override
protected int[] onCreateDrawableState(int extraSpace) {
final int[] drawableState = super.onCreateDrawableState(extraSpace + 1);
if (isChecked()) {
mergeDrawableStates(drawableState, CHECKED_STATE_SET);
}
return drawableState;
}
@Override
public void toggle() {
this.checked = !this.checked;
}
}
5) I am using ActionBarSherlock
lib as well as HoloEverywhere
6) I check ListViews' items with ListView.setItemChecked(...)
Many thanks for any help,
