I have a listview which contains two buttons, when the button is clicked it should open a gallery. I tried to implement it and followed some post on stackoverflow but still I'm not able to get exact result. How to open the gallery using buttons in listViewlistview?
I have tried the following and used the adapter class as inner class
MyAdapter adapter=new MyAdapter(getApplicationContext(),videoFileList);
im my adapter class
private class MyAdapter extends BaseAdapter
{
ImageView picture;
Button imgbtn,videobtn;
ImageButton play;
Context context;
private LayoutInflater inflater;
private ArrayList<String> videolisty;
public MyAdapter(Context context,ArrayList<String> videolistx)
{
this.context=context;
inflater = LayoutInflater.from(context);
videolisty = videolistx;
Field[] arrayOfField = R.raw.class.getFields();
for (int i = 0; ; i++)
{
if (i >= arrayOfField.length)
{
System.out.println("-----------videolist------" +videoFileList);
return;
}
System.out.println("audio files-----" + arrayOfField[i].getName());
videoFilename.add(arrayOfField[i].getName());
Uri localUri = Uri.parse("android.resource://" + Listmodels.this.getPackageName() + "/" + "R.raw." + arrayOfField[i].getName());
System.out.println("--------uri path------" + localUri);
}
}
#Override
public int getCount() {
return videolisty.size();
}
#Override
public Object getItem(int i)
{
return videolisty.get(i);
}
#Override
public long getItemId(int i)
{
return i;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup)
{
View v = view;
final int xx = i;
if(v == null)
{
v = inflater.inflate(R.layout.clistview, viewGroup, false);
v.setTag(R.id.categoryimageView1, v.findViewById(R.id.categoryimageView1));
v.setTag(R.id.uploadimg, v.findViewById(R.id.uploadimg));
v.setTag(R.id.uploadvideo, v.findViewById(R.id.uploadvideo));
v.setTag(R.id.play, v.findViewById(R.id.play));
}
picture = (ImageView)v.getTag(R.id.categoryimageView1);
imgbtn = (Button)v.getTag(R.id.uploadimg);
videobtn = (Button)v.getTag(R.id.uploadvideo);
play=(ImageButton)v.getTag(R.id.play);
imgbtn.setOnClickListener(new OnClickListener() {

}
});
play.setOnClickListener(new View.OnClickListener() {

System.out.println("YEST"+xx);
Intent localIntent = new Intent(Listmodels.this, Videoplay.class);
localIntent.putExtra("videopath", videoFileList.get(xx));
startActivity(localIntent);
}
});
/*picture.setImageResource(item.drawableId);
name.setText(item.name);*/
return v;
}
protected void onActivityResult(int requestCode, int resultCode) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {

String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
System.out.println("------data path-------"+picturePath);
//filechoose.setText(picturePath);
}

I have a recycle View android and there's an image in each item. In that image i want to make a upload function. And I use MVP in this app. SO, There's a fragment, presenter and adapter.
My Fragment

rv.setAdapter(new PendingOrderAdapter(transactionHistories, getContext(), presenter));
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

Cursor cursor = getActivity().getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
file = new File(picturePath);
}
}
}
My Adapter
public class PendingOrderAdapter extends RecyclerView.Adapter<PendingOrderAdapter.PendingOrderHolder> {

The question is how to bring image file to my adapter?
Hello I made android gallery . I added capture image camera or gallery but I show only one image in display How can show two gallery item in gallery For example that is

First, I'm sorry for my bad English. please excuse me. :)..
I tried to make a custom listView which has ImageView, TextViews, and Button.
So, I want to change image after I click ImageView in listview and select image from gallery. But.. It's really hard to me.
In my code(customAdapter)Adapter class is not Activity, So it cannot call startActivityForResult directly. So I make new Activity(It is GalleryImage.java). and call startActivity using that class. But it is not working. What should I do...
(Error occur in ImageView.setOnClickListner, getView of PhoneBookAdapter)

Thanks for your help. :D.
Solution here is not creating a new instance of Activity but being able to access already existing instance created by Android Framework. Instance of an Activity should never be created by an application programmer.
Best approach would be to add a parameter of type Activity to the constructor of PhoneBookAdapter. Such as:
private Activity activity;
public PhoneBookAdapter(Activity activity, ArrayList<Contact> people) {
this.activity = activity;
m_people = people;
m_filteredPeople = people;
}
You can than then call activity.startActivityForResult on this instance of Activity.
You then pass in the instance of Activity when you create the adapter. In Activity you would simply pass this and in Fragment you can obtain the instance by calling getActivity() method of Fragment class.
As to processing the result of the started Activity you would need to implement this in the Activity or Fragment in which you display the list.
I'm beginner in Android. I have two screens. I am switching between the screens, but onActivityResult() is not called in my application. I'm getting my main screen back. I want result of my second screen.
This is my code:
mainActivity.java
loadPicture.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
Intent i = new Intent(context, ImageThumbnailsActivity.class);
startActivityForResult(i, 0);
return true;
}
});

public class ImageThumbnailsActivity extends Activity {
private Cursor imagecursor, actualimagecursor;
private int image_column_index, actual_image_column_index;

super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

setContentView(R.layout.image_gallery);
init_phone_image_grid();
}
private void init_phone_image_grid() {
String[] img = { MediaStore.Images.Thumbnails._ID };
imagecursor = managedQuery(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, img, null,
null, MediaStore.Images.Thumbnails.IMAGE_ID + "");
image_column_index = imagecursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
count = imagecursor.getCount();
imagegrid = (GridView) findViewById(R.id.PhoneImageGrid);
imagegrid.setAdapter(new ImageAdapterClass(getApplicationContext()));
imagegrid.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position,
long id) {
//System.gc();
String[] proj = { MediaStore.Images.Media.DATA };
actualimagecursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj,

//System.gc();
Intent intent = new Intent();
intent.putExtra("filename", i);

finish();
}

Add this to you main activity:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String filename = data.getStringExtra("filename");
}
}
}
It is not obvious that you have overloaded the activity's onActivityResult method.
