I need to set different getPath() for different images . Below is the sample describing getPath for one image . I am not able to understand how to use it for setting 2 images .
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if (cursor != null) {
// HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
// THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} else
return null;
}
Bitmap :-
public void decodeFile(String filePath) {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeFile(filePath, o);
// The new size we want to scale to
final int REQUIRED_SIZE = 70;
// Find the correct scale value. It should be the power of 2.
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp < REQUIRED_SIZE && height_tmp < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
bitmap = BitmapFactory.decodeFile(filePath, o2);
bitmap2 = BitmapFactory.decodeFile(filePath, o2);
imgView.setImageBitmap(bitmap);
imgView2.setImageBitmap(bitmap2);
No actually you do not have to use different getPath for multiple images, you can have single method only for n
number of images,
Look at this below example,
//Button's click event i am openong phone's gallery
but1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
openGallery(SELECT_FILE1);
}
});
but2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
openGallery(SELECT_FILE2);
}
});
where here is a open gallery function.
public void openGallery(int req_code) {
Intent i = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(i, req_code);
}
and inside onActivity result i am setting different path which from which i get images,
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
if (requestCode == SELECT_FILE1) {
selectedPath1 = getPath(selectedImageUri);
editText1.setText(selectedPath1);
}
if (requestCode == SELECT_FILE2) {
selectedPath2 = getPath(selectedImageUri);
editText2.setText(selectedPath2);
}
}
}
and here at last
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
@SuppressWarnings("deprecation")
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
