I'm trying to build an android application that features a graphical display drawn within a RelativeLayout. I want to place "+" and "-" buttons next to several of the parameters, which are drawn at various points on the canvas. The positions are free-form don't seem to conform to any of the standard XML layouts.I know how to create the buttons programmatically, but I don't know how to place them over the canvas where I need them to be. I'm assuming that this would be done in the view thread's doDraw() method, after all the graphics have been drawn, but how?

View 2 Replies View RelatedI would like to change margin of my buttons in application. Suppose I have 5 buttons like this in a linear layout, one below d other. When I focus on a button, its width should increase (which I know how to handle) and at the same time, width should increase linearly towards both left and right. i.e. If the current width of the button is 250 with x co-ordinate as 50 (that means button's left is 50 and button's right is 300), when I focus on the button I should get x co-ordinate as 75 (left = 25 and right = 325). How to change the margin/x co-ordinate of the button?

View 1 Replies View RelatedI have a custom view that I had to write for a large scrollable image, as the images are larger than the size of the screen. Before, I had tried to do it by putting the image into a ScrollView but that of course didn't work. The view itself is within a RelativeLayout within the activity and at the bottom of the screen I have two buttons that are used for navigation and at the top a TextView with a caption for the activity (the main header is already being used here for instruction). In my below code, I've checked the Hierachy Viewer to confirm all the elements are loaded and in the Activity I can see the TextView, however it overlays the ZN5ScrollView area and below the image I just have a blank area of the size defined rather than my buttons. For the bottom navigation, the Hierachy Viewer is saying the absolute_y of the bottom navigation is 480. I'm wondering if anyone can help with my layout code here to get this working correctly? Bottom navigation is 50px high, ZN5ScrollView is 365px above the navigation, and the TextView takes up the rest of the area at the top

View 1 Replies View RelatedMy external button is stuck down, and when I press the power button to wake my phone up it thinks that I am pressing both at the same time. So the phone goes into the Hboot screen, where I cannot choose a function. (because the volume button is stuck down position.) I have to remove the battery and wait about an hour or so then re-insert the battery and pray that it loads up. What can I do to stop this from happening? Or is there a way to control the Hboot screen other than using the volume button?
View 2 Replies View Relatedi've just returned to Android after about a year and a half and I never remember having this "issue" with my old galaxy s2x. But i am finding that whenever i am scrolling down a list, facebook, instagram, or even a webpage, and i hit the back button, it always starts me from the very TOP of the page again. I am used to just hitting back and having it remember my position halfway down or wherever i was. is this just an android thing?!
View 6 Replies View RelatedIs it possible to place buttons at an X,Y position over the top of a Canvas?
For example, on the opening screen of my game, I would like to place buttons for "Play Now", "Instructions", etc, right on top of the canvas.
Right now, I'm looking at Touch locations on the Canvas and comparing them to various X,Y bounds. It works, but adding a button with a click listener would probably be much more efficient.
On my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.

View 2 Replies View RelatedI know this is possible as the built in clock app and other apps are able to do it. How do you turn off the button backlights from code? These would be those like the softkeys on the bottom of the Nexus One screen.
Update: Found this, but it only works on Froyo: WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.buttonBrightness = 0;
I was wondering how we could add objects such as textview and radio buttons to the activity through code and not the XML file and still have it run correctly. I tried adding a simple textview below but I got an error when I tried to run. Can any1 tell me how I could add the textview in correctly? import java.util.ArrayList; import android.app.Activity; import android.os.Bundle; import android.widget.ScrollView; import android.widget.TextView;public class Q_end extends Activity { /** Called when the activity is first created. */ private ArrayList<String> qs = new ArrayList<String>(10); private ArrayList<String[]> as = new ArrayList<String[]>(10); @Override public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState); setContentView(R.layout.end_app); ScrollView we = (ScrollView) findViewById(R.id.viewer); String[] temp = new String[4]; temp[0] = "the"; temp[1] = "the1"; temp[2] = "the2"; temp[3] = "the3"; as.add(temp); String temp2 = "the rocks says"; qs.add(temp2); qs.add("the question is"); String[] temp3 = new String[1]; temp3[0] = " "; as.add(temp3); TextView gg = new TextView(null); gg.setText(qs.get(0)) we.addView(gg);
View 4 Replies View RelatedI can't seem to find anywhere a way to programmatically change the the alignment of the button.
In the XML it is simply layout_gravity="Center" or something.
How do we do this in the code?
LayoutParams do not seem to cater for this.
I'm not sure what's wrong here, all i want to do is randomly grab an item from my array. Which is just like a random sentence. Then generate another once the button is pressed. All my code looks good to me but it's causing a crash when i hit the button. any ideas?
View 1 Replies View RelatedI was trying to do a memory game on android, but i can't figure out the code that matching 2 button with the same image..
CODE:..................
First of all, maybe i went about this the wrong way in the first place. Situation is, i have a listview that when an item is clicked, it creates an intent and calls startActivityForResult() to another activity, to be able to edit the entries in the row. and that other activity after editing the required values, returns back to the calling activity, when the user clicks on a save button. The activity then uses the row Id to update the item.My problem now is that, if the user presses the BACK button instead, the application crashes. i have been looking around and see solutions like using Shared Preferences or onSavedInstanceState(), but i don't know where exactly i should be putting the code?

I have a Relative Layout.
Which has 2 buttons, side by side and it is right-aligned.
So this is my layout xml file. My question is there are no spacing between the right-most button and the right border of the RelativeLayout and between the 2 buttons. How can I add that? I play with android:paddingRight, but nothing helps. code...

View 5 Replies View RelatedI know my original post (at http://groups.google.com/group/android-developers/browse_thread/threa..., I could not find a way to perform a reply, maybe it's too old) is not sexy, but I'm now facing that problem in many situations. Let me please rephrase what I attempt to do, and what my problem is.
I have a RelativeLayout made of three widgets (named 1, 2 and 3 on the illustrations below): one attached to its parent left border (labelled 1), one to its parent right border (labelled 2) and the third (labelled 3) inserted between the 2 previous ones (its left border is attached to the first widget right border, and its right border is attached to the second widget left border). The third widget (the middle/central one laballed "3") is far taller than the two others, and I would like the first and second items (1 and 2) to be vertically centered with the middle widget.
I have resorted to the "android:layout_centerVertical" attribute for both the first and second widget, but I do not get the expected result. See at the bottom the various layouts I'm mentionning. Could someone please help me, and tell me whether what I intend to do is feasible, and how? Thank you for your time.
Layout with no "android:layout_centerVertical" specified: ------- |1|3|2| --|3|-- |3| ---
Layout with "android:layout_centerVertical" set to "true":
--- |3| |3| |3| ------- |1| |2| --- ---
What I'd like: --- --|3|-- |1|3|2| --|3|-- ---
I've always been using RelativeLayout everytime I needed a View container, because of it's flexibility, even if I just wanted to display something really simple.Is it ok to do so, or should I try using a LinearLayout when I can, from a performance/good practices standpoint?
