I have an image view in android and on that image view i have another image view.. Both image views contain two different images.. Now i want to save it as a single JPG image in my phone gallery.. So how can i do that??
I tried some code but it is not working.
Here is my code.
XML File:
<ImageView
android:id="#+id/innerImage"
android:layout_width="300dp"
android:layout_height="230dp"
android:layout_centerInParent="true"
android:layout_centerVertical="true"
android:contentDescription="#android:string/untitled"
android:background="#drawable/white"/>
<Button
android:id="#+id/btnselectPhoto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/ivImage"
android:layout_alignLeft="#+id/ivImage"
android:layout_marginBottom="16dp"
android:text="#string/select_photo" />
<ImageView
android:id="#+id/ivImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:contentDescription="#android:string/untitled" />
<Button
android:id="#+id/btnsave"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#id/btnselectPhoto"
android:layout_alignBottom="#id/btnselectPhoto"
android:layout_alignRight="#+id/ivImage"
android:layout_marginLeft="32dp"
android:layout_toRightOf="#id/btnselectPhoto"
android:text="#string/save" />
And here is my Java Code:

I worked on a similar issue once, and i solved it by putting both images in the same linear layout an creating Bitmap from that layout. Than you can just write a function to save that Bitmap where ever you want.
Here's some sample code:
private Bitmap getBitmap(View v) {
v.clearFocus();
v.setPressed(false);
boolean willNotCache = v.willNotCacheDrawing();
v.setWillNotCacheDrawing(false);
// Reset the drawing cache background color to fully transparent
// for the duration of this operation
int color = v.getDrawingCacheBackgroundColor();
v.setDrawingCacheBackgroundColor(0);
if (color != 0) {
v.destroyDrawingCache();
}
v.buildDrawingCache();
Bitmap cacheBitmap = v.getDrawingCache();
if (cacheBitmap == null) {
Toast.makeText(StopWarApp.getContext(), "Something went wrong",
Toast.LENGTH_SHORT).show();
return null;
}
Bitmap bitmap = Bitmap.createBitmap(cacheBitmap);
// Restore the view
v.destroyDrawingCache();
v.setWillNotCacheDrawing(willNotCache);
v.setDrawingCacheBackgroundColor(color);
return bitmap;
}
public void combineImages(Bitmap c, Bitmap s,String loc) {
Bitmap cs = null;
int width, height = 0;
if(c.getWidth() > s.getWidth()) {
width = c.getWidth();
height = c.getHeight() + s.getHeight();
} else {
width = s.getWidth();
height = c.getHeight() + s.getHeight();
}
cs = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas comboImage = new Canvas(cs);
comboImage.drawBitmap(c, 0f, 0f, null);
comboImage.drawBitmap(s, 0f, c.getHeight(), null);
String tmpImg = String.valueOf(System.currentTimeMillis()) + ".png";
OutputStream os = null;
try {
os = new FileOutputStream(loc + tmpImg);
cs.compress(CompressFormat.PNG, 100, os);
} catch(IOException e) {
Log.e("combineImages", "problem combining images", e);
}
}
You can combine two bitmaps using this.
LinearLayout ll;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.layout2);
ll=(LinearLayout)findViewById(R.id.linearlayout);
//Add button in your layout and write the below code onclick of button.
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
ll.setDrawingCacheEnabled(true);
Bitmap bitmap = ll.getDrawingCache();
String root = Environment.getExternalStorageDirectory().toString();
File newDir = new File(root + "/saved_picture");
newDir.mkdirs();
Random gen = new Random();
int n = 10000;
n = gen.nextInt(n);
String fotoname = n + ".jpg";
File file = new File(newDir, fotoname);
String s = file.getAbsolutePath();
System.err.print("Path of saved image." + s);
try {
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
}
}
});

Hi guys, how can I upload the image to my filemanager on my webhost when I click the button rent? As of now I don't start on anything because I tried to upload it the way I upload from gallery and It didnt work. Can you help me guys? As of now I cleaned my code and this is it

Is there any solution to use AQuery library of android for JSON parsing? Do give the code for it. Any solution that makes use of AQuery and no need to create JSONObject instance and to get object from there. Any direct solution for it, please do answer it with a sample of code.

bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(),
bitmapOptions);
Now you can use imagePath anywhere in the class.
I have problem with java class android for upload a file to a remote server.
In the form I select the file on gallery image on smartphone, but the output of bitmap always show null and the form start is blocked.
Log.d("HomeActivity.class", "Output: " + bitmap);
This is beginning to make me believe my structure as a whole is not correct.
What am I missing ?
What's wrong with the code?
I would greatly appreciate any help you can give me in working this problem.

You are starting your upload thread in onCreate. And so bitmap is null. Better start your thread in an onClick handler.
By the way: Log.d("HomeActivity.class", "Output: " + bitmap);. That is awfull trying to print a bitmap. If you want to check if the bitmap is null the do so:
if ( bitmap==null )
Log.d(TAG, "bitmap==null");
else
Log.d(TAG, "we have a nice bitmap");
I save a picture from imageView to SD. The image is saved.
The problem is that there is the first image, and saving the next image again saved the first with a different name.
As I understand need to catch the moment when the picture from imageView is loaded into playImage. But how to do it?
Thank's.
Load the image in imageView and save to sd:
public class Gallery extends Activity implements OnClickListener {
String item;
Button btnsave, btnhome;
ImageView playImage;
String fotoname;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.gallery);
btnhome = (Button) findViewById(R.id.btn_home);
btnhome.setOnClickListener(this);
btnsave = (Button)findViewById(R.id.btn_save);
btnsave.setOnClickListener(this);
playImage = (ImageView)findViewById(R.id.displayImage);
final ImageView playImage = (ImageView) findViewById(R.id.displayImage);
final LinearLayout myGallery = (LinearLayout) findViewById(R.id.mygallery1);
Bundle extras = getIntent().getExtras();
if(extras !=null) {
item = extras.getString("item");
if(item.equals("Item")){
try {
String galleryDirectoryName = "ITEM/item";
String[] listImages = getAssets().list(galleryDirectoryName);
for (String imageName : listImages) {
InputStream is = getAssets().open(galleryDirectoryName + "/" + imageName);
final Bitmap bitmap = BitmapFactory.decodeStream(is);
ImageView imageView = new ImageView(getApplicationContext());
imageView.setLayoutParams(new ViewGroup.LayoutParams(350, 225));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setImageBitmap(bitmap);
imageView.setPadding(10, 70, 10, 70);
imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
playImage.setImageBitmap(bitmap);
playImage.setPadding(5, 0, 5, 0);
}
});
myGallery.addView(imageView);
}
} catch (IOException e) {
Log.e("GalleryWithHorizontalScrollView", e.getMessage(), e);
}
}
}
}
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId()){
case R.id.btn_save:
playImage.setDrawingCacheEnabled(true);
Bitmap bitmap = playImage.getDrawingCache();
String root = Environment.getExternalStorageDirectory().toString();
File newDir = new File(root + "/." + (getString(R.string.app_name)));
newDir.mkdirs();
Random gen = new Random();
int n = 10000;
n = gen.nextInt(n);
String fotoname = "photo-"+ n +".jpg";
File file = new File (newDir, fotoname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();

mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
break;

}
Check this.
