Android :: Trying To Add Image - Setting Layout Parameters
Jul 21, 2010
So Im trying to add an imageview to my current xml design - and its working decently. Now my main problem is that I cant seem to find a way to set the attributes for the image like where it needs to be displayed etc.
RelativeLayout mRelativeLayout = (RelativeLayout) findViewById(R.id.board);
ImageView i = new ImageView(this);
i.setImageResource(R.drawable.blue_1);
i.setAdjustViewBounds(true);
mRelativeLayout.addView(i);
setContentView(mRelativeLayout);
i tried messing around with setlayoutparams but got absolutely no clue what to do with it.

I'm programmatically adding views to a LinearLayout inside a ScrollView and i'm running into some issues setting margins and padding etc for child views of the LinearLayout.
i've tried child.setPadding() and adding the view with a MarginLayoutParams set up right, but the child view still fills the parent width.
what is the correct way to programmatically set the parameters which are set statically by layout_marginLeft, layout_marginRight, etc?

I like the layout of the toast widget very much, that means rounded corners, transparency, light grey border. Is there any way to see the layout parameters of such android standard widgets like the toast? I would like do define a TextView with the same layout parameters.

Is it possible to build a GridView object in XML with 3 columns and 4 rows of Image buttons? It doesn't seem to have similar containment relationship like LinearLayout or RelativeLayout viewgroups.
I want to do this entirely in an xml layout file. When I put ImageButton xml tags inside a GridView xml body, The layout panel in eclipse is throwing an exception: UnsupportedOperationException:addView(View, LayoutParams) is not supported in AdapterView.

simple question. In a class, if I wanted to set the text to the text value of a string I have, what is the code for that?
I have: TextView textView = (TextView) findViewById(R.string.noFaceFive); textView.setText(textView);
but setText says : The method setText(CharSequence) in the type TextView is not applicable for the arguments (TextView)
is there a set Text to display the text of a string? Serious mind fart on my part.

Is there a way to specify a background in a layout based on OS version?:
android:background_1.5="@color/white"android:background_above_1.5="@drawable/mybackground"
I'm running into a problem where using a 9 png drawable for the background causes a stack overflow exception on a listview item (stack trace shows its related to a child TextView -> drawText()). The layout is simple:
<LinearLayout><ImageView /><TextView /></LinearLayout>
and the background works fine on 1.6 and above. It's just 1.5 that's having the issue. If I set the background to be a color, it works fine.

I've got a ListActivity using the Theme.Dialog theme and windowNoTitle set to true.
Unfortunately, when I do this, the header rows (just normal rows in the list but they look like sub headers) refuse to fill_parent width (instead, they wrap_content - the header text).
I noticed this was not a problem when using the Theme theme so I started narrowing everything down to what was causing the problem.
The answer: windowIsFloating. Theme.Dialog sets this to true, and if I override this to false, then the headers happily fill the parent width.
Is there a way around this (because I would like to set windowIsFloating to true)?

At the moment I am attempting to set my camera on my Motorola Droid phone to take an image that matches the size of my screen (854 x 480 pixels), and I am attempting to accomplish via the parameters for the camera as such:
CODE:.................
I have my activity implement the Camera.PictureCallback method of onPictureTaken (excluding log calls), so when the takePicture method is called it runs this method:
CODE:..........
For some reason though, my camera is taking pictures in 1280 x 960. Is this some sort of minimum size the camera can capture an image in? From log calls I can see that the Camera's parameters are still set to have a picture size of 854 x 480, but image keeps coming out as 1280 x 960. Am I decoding the image incorrectly, am I setting the camera's parameters incorrectly, or am I doing something else wrong?

I'm setting background color based on a given state of an object in each row in a list. That part is working just fine but when I set the background color on the outermost layout the row no longer highlights when selected. Probably a specific attribute I'm not setting/changing?

i've got this simple layout in a file derived from Activity
<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dip" > <ImageView android:id="@+id/photo" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </ScrollView>
i'd like to change the imageview contents dynamically. which method do i need to overload - again this class is derived from Activity.

I 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 want to create an Android ImageButton in the xml file with a background image, and a smaller icon on top of that, right in the center. For some reason, it's not obvious how to do it, and documentation is no help.code...
However, no matter what I try (putting "wrap _ content" instead of absolute numbers on layout _ height and layout _ width, the icon remains in the top left corner of the button. If, however, I have no background image (i.e. a system default white button), the icon does go into the center. The button also goes into the top left corner when I use a color instead of an image for the background.
Why does this happen, and how would I actually get the behavior I want-- that is, a background image with the icon in the center?

I am trying to create a screen (in portrait mode) that shows 4 images (same size, intended to scale down to fit screen), taking up the entire screen, breaking up the screen into quadrants (a tall, 2x2 grid). This will act as a main menu type of activity and each image should be clickable, in order to take the user to a different activity.
I have tried using a GridView inside a LinerLayout (using a lot from Google's GridView tutorial) but cannot get the images to all scale properly to fill the entire screen. I get extra margins around the images and/or scrolling of the entire screen. I have also tried using a TableLayout, placing 2 images in each of the 2 rows. Visually, that worked perfectly. Unfortunately when using that, I cannot seem to reference the ImageView items in the TableLayout in my activity code (findViewById always returns null)..................

Can you please tell me if there is a way to layout textaround an image?I have gotten a response from an android developer about this question. But I am not sure what he means by doing my own version of TextView? Thank for any tips.This is not possible using only the supplied widgets and layouts. could write your own version of TextView to do this, it shouldn't be hard.

so hopefully this question/problem isn't as simple/dumb as my previous.I've somehow messed up my keyboard settings or language. the bottom right and bottom left buttons now have some Chinese/Japanese text on them and the bottom left button turns on some alternative keyboard options and changes my text output to Japanese.Now I presumed this was simply something in my language settings but I've set them back to UK and still no joy.I'm also using Handcent sms and the Handcent keyboard ui but that's not displaying either. Tried un-install/reinstall but no luck.

In my android application i am using a image as background initially. Then on top of that i need to place small images and on top of the small images i would like to place a textview with some text on it.
I am using below code for that.With this am able to place the small images but the textview if i am trying to place it place in the next row and not over the image.
I also tried with adding the image as the background and then placing textview but at that case the padding and size of the image is not getting decreased.
Is there any way that i can have the images of size 60 by 60 and place a textview on top of these images.
Please share your valuable suggestions.
