i am working on a image swipe app in which i am swiping images on ViewPager and i want to save current showing image to sd card on button click.
my code: SwipeActivity.java
package com.td.gridview;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.view.PagerAdapter;

import android.widget.ImageView;
public class SwipeActivity extends Activity {
protected int curruntPosition;
protected int hh;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.swipe_view);
// get intent data
Intent i = getIntent();
// Selected image id
final int position = i.getExtras().getInt("id");
final ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
ImagePagerAdapter adapter = new ImagePagerAdapter();
viewPager.setAdapter(adapter);
viewPager.setCurrentItem(position);
viewPager.setOnPageChangeListener(new OnPageChangeListener() {
#Override
public void onPageSelected(int arg0) {
// TODO Auto-generated method stub
// Here you can set the wallpaper
curruntPosition = arg0;
if (curruntPosition == arg0) {
hh = 1;
}
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
#Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
});
//
Button bx = (Button) findViewById(R.id.xoom);
bx.setOnClickListener(new View.OnClickListener() {
public void onClick(View vx) {
// // TODO Auto-generated method stub
if (hh == 1) {
// Sending image id to FullScreenActivity
Intent i2 = new Intent(getApplicationContext(),
Full_Zoom.class);
// passing array index
i2.putExtra("id", curruntPosition);
startActivity(i2);
} else {
// get intent data
Intent i3 = getIntent();
// Selected image id
int position = i3.getExtras().getInt("id");
// Sending image id to FullScreenActivity
Intent i2 = new Intent(getApplicationContext(),
Full_Zoom.class);
// passing array index
i2.putExtra("id", position);
startActivity(i2);
}
}
});
//
// Save ViewPager current image to sd card on button click
Button b1 = (Button) findViewById(R.id.wll);
b1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v2) {
// // TODO Auto-generated method stub

}
});
}
public class ImagePagerAdapter extends PagerAdapter {
int[] icons = MainActivity.ICONS;
#Override
public int getCount() {
return icons.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
Context context = SwipeActivity.this;
ImageView imageView = new ImageView(context);
// int padding = context.getResources().getDimensionPixelSize(
// R.dimen.padding_large);
// imageView.setPadding(padding, padding, padding, padding);
imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
imageView.setImageResource(icons[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
}
}
in this above code find this code: here i want to perform save image from viewpager to sd card
// Save ViewPager current image to sd card on button click
Button b1 = (Button) findViewById(R.id.wll);
b1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v2) {
// // TODO Auto-generated method stub
// Save ViewPager current image to sd card
}
});
Try something like this:
String filename;
Bitmap imageBitmap;
//....
//set file name and bitmap
//....
File imageFile = new File(Environment.getExternalStorageDirectory(), filename);
FileOutputStream out;
try {
out = new FileOutputStream(imageFile);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
outStream.flush();
outStream.close();
success = true;
} catch (Exception e) {
Log.e(TAG, "Error writing to file: ", e);
} finally {
if (out != null) {
try {
out.close();
} catch (IOException e) {
Log.e(TAG, "Error closing file: ", e);
}
}
}
i found my answer:

You're missing some braces and semicolons, and you've got an #Oveerride in there as well.
Try this, it should compile:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Gallery gallery = (Gallery) findViewById(R.id.gallery1);
//create adapter Gallery
gallery.setAdapter(new ImageAdapter(this));
imageView = (ImageView) findViewById(R.id.imageView1);
gallery.setOnItemClickListener( new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int arg2, long arg3) {
Toast.makeText(getApplicationContext(), "pic:" + arg2, Toast.LENGTH_SHORT).show();
imageView.setImageResource(pics[arg2]);
}
});
// look for the button we set in the view
ImageButton cameraButton = (ImageButton)
findViewById(R.id.button_camera);
// set a listener on the button
cameraButton.setOnClickListener(cameraListener);
}
Right I've looked at a shed load of tutorials, questions and so on but none have worked, so I don't need more links, I just need a fix for my current code..
So far I have this:
public class FullscreenActivity extends Activity {
protected int[] mThumbIds;
#SuppressWarnings("unused")
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fullscreen);
// get intent data
Intent i = getIntent();
// Selected image id
final int position = i.getExtras().getInt("id");
ImageAdapter imageAdapter = new ImageAdapter(this);
ImageView imageView = (ImageView) findViewById(R.id.full_image_view);
Button SetWallpaper = (Button)findViewById(R.id.setwallpaper);
imageView.setImageResource(imageAdapter.mThumbIds[position]);
}
private Object[] imageIDs;
private int position;
public void onClick(View arg0) {
try {
WallpaperManager.getInstance(this).setResource((Integer) imageIDs[position]);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
But when I click the button once the picture has been selected, it doesn't do anything?
I also have the permission in the manifest but it still doesn't work, so any help would be hugely appreciated
Thank you
I'm not sure if this has anything to do with it or not but I'm testing the app on a Samsung Galaxy S4
May be it can relate..

I've googled so much but I can't figure out what's wrong.
Any help would be really appreciated.
I solved it writing the following lines where you declare everything for the activity, before onCreate:
static {
if (!OpenCVLoader.initDebug()) {
// Handle initialization error
}
}
confirm your native_sample.so file has been contained in your libs-->armeabi folder, and usually, the native lib should be loaded in a static code block outside of the activity's life circle methods.
I'm really frustrated because of bad programming style, and inexperience in Android. Sorry to tell you guys that.
How the app works:
This is a todo app for my job training. There are 6 columns.
3 of these contain information about the todo and the other 3 contain a view detail, edit, and remove screen.
When the user clicks remove for some reason even after setting a notifyDataChange, my screen is not updated and the deleted row it's still displayed.
Any ideas of what is going on here? I've tried many solutions for about 3 hours now
The code is posted here sorry if its a bit tedious.

The delete method:
public void delete(int position) {
theDatabase.beginTransaction();
try {
theDatabase
.delete(DATABASE_TABLE, KEY_ROWID + "=" + position, null);
theDatabase.setTransactionSuccessful();
} catch (SQLiteException e) {
// TODO: handle exception
e.printStackTrace();
} finally {
theDatabase.endTransaction();
theDatabase.close();
}
}
before notifyDataSetChanged you need to remove the entry from the List
Did you see any exception when deleting from database. and you also need to delete pos entry from global list before notifying.
I've got an activity that presents a listview of tracks of songs. When an item is clicked, it streams the appropriate media file. I have a textview in each row that displays the length of the track. When the track is playing, I switch the backgroundresource of the textview in the row to a pause button drawable. In other words, when it's ready to play, it displays a play button and when its currently playing it displays a pause button. Simple enough....
Currently, I'm doing something like this to set the drawable to pause button if the mediaplayer is playing:
if(mp.isPlaying()) {
_player.setBackgroundResource(R.drawable.pausebtn);
_player.setText(" :" + String.valueOf(mp.getDuration()/1000));
I'm doing this in my Runnable which has the mediaplayer callback of onPrepared.
Problem is that I need the drawable to be set in THAT list item, i.e. the one which was clicked and whose track is being played. How can I grab hold of which one was clicked and set ITS textview to the new drawable?

As you can see, my inner class AudioCell which extends RelativeLayout is what I'm using for the rows of my ListView....
Any thoughts? Where should I be setting the drawable and how can I make sure it does it only for the row that was clicked (i.e. for the track that's actually being played).
change the TrackClicked method's siggnature. pass both arg1 and arg3 from onItemClick and in the TrackClicked method do this arg1.setBackgroundResource(R.drawable.thebackground);
Inside your TrackClicked method, add this:
getAdapter().getChildAt(arg2).setBackgroundResource(R.drawable.thebackground);
