[android-beginners] Saving Pictures from /drawable in a app to SD Card
I kind of confussed and hope one of you nice people will help me.
I have written a app, and I have pictures which are stored in the /
drawable directory. My app makes a sliding gallery across the top,
(id gallery1) and as you select the picture in the gallery it load the
picture bigger underneath, (id image1). These a layed out in a XML
file. What I would like to do is be able to is when the image1 is
pressed it gives the option to save the picture on the SD Card.
My Whole Code is:
*
public class PicViews extends Activity
{
//---the images to display---
Integer[] imageIDs = {
R.drawable.pic01,
R.drawable.pic02,
R.drawable.pic03,
R.drawable.pic04,
R.drawable.pic05
};
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.displayview);
Gallery gallery = (Gallery) findViewById(R.id.gallery1);
gallery.setAdapter(new ImageAdapter(this));
gallery.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView parent,
View v, int position, long id)
{
//---display the images selected---
ImageView imageView = (ImageView)
findViewById(R.id.image1);
imageView.setImageResource(imageIDs[position]);
}
});
}
public class ImageAdapter extends BaseAdapter
{
private Context context;
private int itemBackground;
public ImageAdapter(Context c)
{
context = c;
//---setting the style---
TypedArray a =
obtainStyledAttributes(R.styleable.Gallery1);
itemBackground = a.getResourceId(
R.styleable.Gallery1_android_galleryItemBackground,
0);
a.recycle();
}
//---returns the number of images---
public int getCount() {
return imageIDs.length;
}
//---returns the ID of an item---
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
//---returns an ImageView view---
public View getView(int position, View convertView, ViewGroup
parent) {
ImageView imageView = new ImageView(context);
imageView.setImageResource(imageIDs[position]);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setLayoutParams(new Gallery.LayoutParams(150,
120));
imageView.setBackgroundResource(itemBackground);
return imageView;
}
}
}
*
The Section of code which pulls up the image and makes the bigger
picture show is:
*
gallery.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView parent,
View v, int position, long id)
{
//---display the images selected---
ImageView imageView = (ImageView)
findViewById(R.id.image1);
imageView.setImageResource(imageIDs[position]);
}
});
**
Its at this point I want to be able to have a option to save the
picture either by pressing a button or ideally pressing the picture
which will bring up options.
Also what alterations in the manifest do I need to make to be able to
access the SD Card Storage?
Please help, I'm only learning.

[android-beginners] Saving contents of a Spinner with onSaveInstanceState
I've got an app that uses a Spinner tied to an Adapter. I want to be
able to save its contents when onSaveInstanceState is called, but am
not sure which put method of the Bundle class I can use to do this?
protected void onSaveInstanceState(Bundle outState) {
//TODO: Figure out how to save mDirectories (spinner)
outState.putString(mStatus, mStatus.getText().toString());
outState.putString(mPath, mPath.getText().toString());
//outState.putSerializable(mDirectories, mDirectories); --
Spinner object
outState.putStringArray(links, links);
outState.putInt(linksPointer, linksPointer);
super.onSaveInstanceState(outState);
}

You do not want to put a Spinner in the onSaveInstanceState() Bundle.
Besides the fact that it is impossible, doing so would cause your new
activity to hold onto a reference to that Spinner, which holds onto a
reference to your old activity, which will cause a substantial memory
leak.
Your Spinner's contents are set via some sort of Adapter. You should
be making sure your new Activity can re-create that Adapter. Then, put
either getItemSelectedId() or getItemSelectedPosition() in the Bundle,
so you can restore the selection in the new Activity.

[android-beginners] Saving calculator result problem
Hi. I am trying to hack this bit of code to save the results of a
calculation to disk but it says that the variable (txt) cannot be
resolved.
Any ideas!
private void handleEquals(int newOperator) {
if (hasChanged) {
switch (operator) {
case 1:
num = num + Double.parseDouble(txtCalc.getText().toString());
break;
case 2:
num = num - Double.parseDouble(txtCalc.getText().toString());
break;
case 3:
num = num * Double.parseDouble(txtCalc.getText().toString());
break;
case 4:
num = num / Double.parseDouble(txtCalc.getText().toString());
break;
}
String txt = Double.toString(num);
txtCalc.setText(txt);
txtCalc.setSelection(txt.length());
readyToClear = true;
hasChanged = false;
}
FileOutputStream fOut = openFileOutput
(samplefile.txt,MODE_WORLD_READABL E);
OutputStreamWriter osw = new OutputStreamWriter(fOut);
osw.write(txt);
osw.flush();
fOut.close();
osw.close();
operator = newOperator;
}

[android-beginners] Saving
I am trying to understand what data is saved when I change the phone's orientation. For instance, I have a couple guys walking around and when I flip the orientation, they are still there walking. However, in a different part of code, I also spawn more guys, but this time, they wont be there when I flip the orientation. So how would one be saved while the other isn't?

[android-beginners] saving data to text file using eclipse
Hi everyone,
I am trying to save data to my google phone G1. I am able to create
the text file in sdcard by using the following code in eclipse :
//++
try {
FileWriter f = new FileWriter(/sdcard/test.txt);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//+
but I am not able to save any data to the created file. I found this
code from http://www.anddev.org/working_with_files-t115.html; which
says I can write to text file by running this code.
//+++
try { // catches IOException below
final String TESTSTRING = new String(hello);
FileOutputStream fOut = openFileOutput(/sdcard/test.txt,
MODE_WORLD_READABLE);
OutputStreamWriter osw = new OutputStreamWriter(fOut);
// Write the string to the file
osw.write(TESTSTRING);
// ensure that everything is
// really written out and close
osw.flush();
osw.close();
} catch (IOException ioe) {
ioe.printStackTrace();
}
//+
I run it but I do not see any change in my file.
first, I thought my problem is permission to file. The permission
setting on my phone is:
data: drwxrwx--x
sdcard: d---rwxrwx
system: drwxr-xr-x
would you please help me in either in correcting the code or finding a
way to save data into text file (saved in sdcard or the phone) in
eclipse environment
thanks in advance

[android-beginners] Saving a preference isn't working
I have a screen where a user can enter information about a Favorite drink. I want to save it to be recalled in the current an future sessions, but the save doesn't seem to be working. Here is my code where I do the save. getPreferences( MODE_PRIVATE ).edit().putString( DrinkName , FavName); getPreferences( MODE_PRIVATE ).edit().putFloat( Volume , ( float ) AlcVol); getPreferences( MODE_PRIVATE ).edit().putFloat( Percent , ( float ) AlcPerc); getPreferences( MODE_PRIVATE ).edit().commit(); MODE_PRIVATE ).edit().putString( DrinkName , FavName); getPreferences( MODE_PRIVATE ).edit().putFloat( Volume , ( float ) AlcVol); getPreferences( MODE_PRIVATE ).edit().putFloat( Percent , ( float ) AlcPerc); getPreferences( MODE_PRIVATE ).edit().commit(); MODE_PRIVATE ).edit().putFloat( Volume , ( float ) AlcVol); getPreferences( MODE_PRIVATE ).edit().putFloat( Percent , ( float ) AlcPerc); getPreferences( MODE_PRIVATE ).edit().commit(); MODE_PRIVATE ).edit().putFloat( Percent , ( float ) AlcPerc); getPreferences( MODE_PRIVATE ).edit().commit(); MODE_PRIVATE ).edit().commit(); Here is the code where I try to retrieve the saved infromation. String strName = getPreferences( MODE_PRIVATE ).getString( DrinkName , ); float fVolume = getPreferences( MODE_PRIVATE ).getFloat( Volume , ( float ) 0.0); float fPercent = getPreferences( MODE_PRIVATE ).getFloat( Precent , ( float ) 0.0); MODE_PRIVATE ).getString( DrinkName , ); float fVolume = getPreferences( MODE_PRIVATE ).getFloat( Volume , ( float ) 0.0); float fPercent = getPreferences( MODE_PRIVATE ).getFloat( Precent , ( float ) 0.0); float fVolume = getPreferences( MODE_PRIVATE ).getFloat( Volume , ( float ) 0.0); float fPercent = getPreferences( MODE_PRIVATE ).getFloat( Precent , ( float ) 0.0); float fPercent = getPreferences( MODE_PRIVATE ).getFloat( Precent , ( float ) 0.0); When I retrieve the information, I always end up with the Default values.

[android-beginners] Saving image to SD Card
I'm using Android SDK-1.0_rc2 on windows, I've emulated the sd card
and created on my D:\ drive as sdcard1.iso. My code for saving to the
SD card is as follows:
try
{
Log.e(filename,filename);
String filepath=Environment.getExternalStorageDirectory
().getAbsolutePath();
Log.e(FilePath,filepath);
FileOutputStream fos = openFileOutput(filepath +
filename, MODE_APPEND);
BufferedOutputStream bos = new BufferedOutputStream
(fos);
b.compress(CompressFormat.JPEG, 100, fos);
bos.flush();
bos.close();
}
When I view the Logcat I see the following error:
java.lang.IllegalArgumentException: File /sdcardobama.jpg contains a
path separator
So I changed the code to:
FileOutputStream fos = openFileOutput(filepath + / + filename,
MODE_APPEND);
The error is still occuring, so I tried to push the image using the
command:
adb push obama.jpg /sdcard/obama.jpg
I noticed 0 bytes are being pushed, any idea where I'm going wrong?
