I'm trying to set the z order of a UI element (i.e. a View) so that it will overlap another element, but calling ViewGroup.bringChildToFront() has a weird side effect....it moves the element to be the last item in the parent (the ViewGroup). Is this a bug, expected behavior, or what? More importantly, how can I set the z order or a View without this unfortunate side effect?

I have an XML layout with some custom tabs, a heading, and a ProgressBar(main.xml). I wish to add another XML layout(home.xml) to the main.xml layout, as i wish to keep main.xml re-usable for other activity's layouts and simply add things to it as necessary.The problem: after inflating R.layout.home into rootLayout, it seems as though the ProgressBar contained in rootLayout is hidden underneath the content of home.xml.Is there a way to tell certain views(via XML) to float above other views when the layout is constructed in this way?if not, am i forced to use methods such as progressBar.bringToFront() to raise targeted views to the top?what alternatives do i have in z-ordering views when some layouts are constructed using inflation?
View 2 Replies View RelatedI have a list view with several columns; things such as name, date, etc. I want to be able to click on the header TextView and sort the list by that field. When the list loads the variable works, and a list is queried and sorted by the field _id (no surprise other than it works), but when i click on the header TextView I get a force close:

The TextView gives no errors when not changing my orderby variable.
Setting Variable:

SimpleCursorAdapter notes =
new SimpleCursorAdapter(this, R.layout.notes_row, notesCursor,
from, to);
setListAdapter(notes);
}
Query (In DB Adapter):

please suggest me how to use bringchildtofront in the listview of an activity.

My main Layout is Absolute Layout and inside that i am using child views(each view is on Relative layout) .Inside Main Layout ,i have 5 sub Layouts ,(5 child views)by changing the x position.and i am giving the x positions like ,all the child's will overlap some part of the view(25%)with the next view. Now what i want to do is ,i want to set one view always should be on the top of the the next view. Is there any way to set Z order of the view so that it will be on the top of another view or on below of the another view .I need to change the Z order. If any body knows pls give me any idea.
View 4 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 got my desire just a few weeks back and the phone is the best one i used till now...Better than the iphone..But the sms threaded view in my phone is not being stored in order for some contacts.

View 1 Replies View RelatedI am trying to create a drawable in code and change the color based on some criteria. When I try and set the Drawable as the background of the ImageView it displays but won't let me set any padding. I realized I need to set the ImageView image via the setImageDrawable() function in order to be able to set the padding. The problem I am running into is that when I set it via the setImageDrawable() function nothing is displayed.
Here is what I have written:
<?xml version="1.0" encoding="utf-8"?>
ImageView icon = (ImageView) row.findViewById(R.id.icon);
ShapeDrawable mDrawable; int x = 0; int y = 0;
int width = 50; int height = 50;
float[] outerR = new float[] { 12, 12, 12, 12, 12, 12, 12, 12 };
mDrawable = new ShapeDrawable(new RoundRectShape(outerR, null, null));
mDrawable.setBounds(x, y+height, x + width, y);
switch(position){ case 0: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 1: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 2: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 3: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 4: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 5: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 6: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 7: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 8: mDrawable.getPaint().setColor(0xffffff00); //Yellow break;
case 9: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 10: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 11: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 12: mDrawable.getPaint().setColor(0xffa020f0); //Purple break;
case 13: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 14: mDrawable.getPaint().setColor(0xffffd700); //Gold break;
case 15: mDrawable.getPaint().setColor(0xffff6600); //Orange break;
} icon.setImageDrawable(mDrawable); icon.setPadding(5, 5, 5, 5);
This results in a space for the ImageView but no image.
I have built an app for the Motorola Droid which should automatically update a server with the phone's location. After the user performs a particular task on the main activity screen, an alarm is set to update the user's location periodically, using a service. The alarm is explicitly stopped when the user completes another task. Thing is, I have set up a location manager within the main activity's onCreate() method which is supposed to place the first acquired lat/long into two textview fields. Even though the manifest is set up for acquiring coarse and fine coords and I'm using requestLocationUpdates (String provider, long minTime, float minDistance, LocationListener listener), with minTime and minDistance set to zero, I'm not seeing the coords coming up on the screen.
With that, I'm not recording any locations on the server. When I seed the textviews with sample coords, they are being recorded fine on the server. I am not at a computer that can run the IDE, so don't currently have the code, but am desperate for some help on this. One other thing is that the main activity screen calls a photography app before the user manually clicks "send data". I'm suspicious that I may need to override the main activity's onResume() method to do this location acquisition.
Can someone know the answer tell me which is more efficient if the bmp is a big bmp? RemoteViews views
1. views.setImageVIewBitMap(R.id.icon, bmp)
2. bmp = BmpUtils.resizeToFitIconSize(bmp) views.setImageVIewBitMap(R.id.icon, bmp)
In short, will resizing the bmp before setting it on a remote view make it more efficient? Or should I just let the imageView take care the resizing? Code...

In ProgressDialog's documentation it says:"A dialog showing a progress indicator and an optional text message or view. Only a text message or a view can be used at the same time."I've gotten it working beautifully with a message, but I want to use a custom view instead - a message with a cancel button.

I've tried it with just a TextView with the text "hello", but it doesn't show up.

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
I want to build my own custom view which should look like the Crysis-GUI.At first I designed a XML-based Layout and made it visible via the setContentView(int resid)-Method. Worked pretty well.But now I wan't to go a step further and draw in my Layout. So I created a new Class, let it extend View and overrode the onDraw()-Method. So far so good.But how can I still use my XML-Layout? I can't do setContentView anymore, so how could the same effect be achieved?
