I want to remove the first line from my ListView.
View 6 Replies View RelatedI have a ListView backed by customized ArrayAdapter where each item has 2 LinearLayouts - one I call head, and the other one - body. The body is hidden (gone) until user clicks on the row at which time it slides out. The second click (on the head) will hide the body. However if user clicks on the body it brings another activity. All of this works just fine, here comes the problem.When user presses on body I want a visual indication of the action just the same way as regular list item will flicker an orange background when pressed. I'm not getting this by default since (my theory) the onPress event is intercepted by body's view and not processed by the list item.The first thing I tried was to execute body.setBackground('#ff00ff') (never mind the color) in onPress event. That didn't work since (I suspect) there's no repainting after the call. Then I dig a little bit more and decided to use <selector/>-based background. I defined body_background.xml in drawable folder and assigned that to the body's background property.
There I noticed that background will only change if the even is processed by the list. For example if I set <item android:state_selected="true" android:drawable="@drawable/selected"/> then when I press on the head - the background of both elements (head and body) will change, however when I press on body - nothing. So to summarize my question.how do I change background of the child element in the list item if I assign custom onClick handler to it?
How to remove item from a list view? how to reload the list after removal?
View 3 Replies View RelatedI am new to android, and ended up (have to) ask a question here. Let's make it simple, I simply want to make my own TextView-like (MyView extends View), This is my code:
public class MyView extends View { private Paint mPaint;
private String mText; private Bitmap mBitmap1; private Bitmap mBitmap2;
public MyView(Context context) { super(context); initView(); }
public MyView(Context context, AttributeSet attrs) { super(context, attrs);
initView(); } private final void initView() { mPaint = new Paint(); }
public void setText(String text) { mText = text; }
@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int measuredWidth = measureWidth(widthMeasureSpec);
if (mBitmap1 == null) initBitmap1(measuredWidth);
int measuredHeight = measureHeight(heightMeasureSpec);
setMeasuredDimension(measuredWidth, measuredHeight);
}
private void initBitmap1(int measuredWidth) {
mBitmap1 = Bitmap.createBitmap(measuredWidth, Fonts.getHeight(), Bitmap.Config.ARGB_4444);
Canvas canvas = new Canvas(mBitmap1 ); canvas.drawText(mText, 0, 0, mPaint);
} private void initBitmap2() {
mBitmap2 = Bitmap.createBitmap(30, Fonts.getHeight(), Bitmap.Config.ARGB_4444);
Canvas canvas = new Canvas(mBitmap2); canvas.drawText(mText, 0, 0, mPaint);
} private int measureWidth(int widthMeasureSpec) {
int measuredWidth = 0; int specWidthMode = MeasureSpec.getMode(widthMeasureSpec);
int specWidthSize = MeasureSpec.getSize(widthMeasureSpec);
if (specWidthMode == MeasureSpec.EXACTLY) { measuredWidth = specWidthSize;
} else { measuredWidth = getWidth(); if (specWidthMode == MeasureSpec.AT_MOST) {
measuredWidth = Math.min(measuredWidth, specWidthSize);
} } return measuredWidth; }
private int measureHeight(int heightMeasureSpec) {
int measuredHeight = 0; int specHeightMode = MeasureSpec.getMode(heightMeasureSpec);
int specHeightSize = MeasureSpec.getSize(heightMeasureSpec);
if (specHeightMode == MeasureSpec.EXACTLY) { measuredHeight = specHeightSize;
} else { measuredHeight = 80; if (specHeightMode == MeasureSpec.AT_MOST) {
measuredHeight = Math.min(measuredHeight, specHeightSize);
} } return measuredHeight;
} @Override protected void onDraw(Canvas canvas) {
super.onDraw(canvas); canvas.drawBitmap(mBitmap1, getLeft(), 0, mPaint);
initBitmap2(); canvas.drawBitmap(mBitmap2, getLeft(), 30, mPaint);
} }
In my code, I populate some numbers of MyView (let's say 20) in a ListActivity. My question is why mBitmap1's order changes randomly while i scroll (up-down) fastly (if I scroll slowly, this problem not occur)? mBitmap2 stays where those should be.
I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item.For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example.I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure.

Below is a simplified version of what I am creating. Unfortunately the list covers(i.e. above on the z axis) the header so the header text is not visible instead of being underneath (on the y axis)

View 1 Replies View RelatedI have an issues, I want to show 20 items in the list.
But there is a catch: if the user scrolls down to the bottom of the list, there will be an item that says: "Show more items", and when the users click on it, more items will be added to the list.
My question is how is poosible to have a last item, that has a different style and looks different: and does different things,(I think this is used in QuickSearchbox)

When I click on the ImageButton "arrow", I trigger a method than need the id of the row to perform. By ID I mean the value of the field "_id" of the corresponding record in database. I did not find a direct way to do it, but I think I can if I get the index of the row in the ListView. Again, I don't know how to get this index from a click to a childview.

My application show a ListView with a button which allow user to add an element. When the user clicks on this button, another Activity is started to allow user to populate the new element. When the add is finished, we return to the previous Activity with the ListView and I would like to scroll to the new element.
Note that this element is not necessarily at the end of the ListView because there is an "order by" when I retrieve the datas from the database. I know I need the cursor position of the new element to make the ListView scrool to it, but the only info I have about this element is its id, so how to convert this id to cursor position ? Do I have to loop on the cursor to find the position?
