Im trying to do this:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
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();
Bitmap bmp = BitmapFactory.decodeFile(picturePath);
b[1].setCompoundDrawablesWithIntrinsicBounds(null, new BitmapDrawable(bmp), null, null);
}
But it wont set the image, no matter what. I have tried several different methods too, like using an imagebutton instead of a button and using:
imageButton.setImageBitmap(bmp)
The gallery opens fine and and the callback comes to onActivityResult(...)
but the image wont appear on the button, I have an array of buttons.
I made a rapid test. The following code works for me. If with this you still can't set the image I would check if there's a layout problem (i.e. the image is set but there's no room to show it).
activity_main.xml has just an ImageButton set to wrap_content, inside the main layout which is match_parent.
public class MainActivity extends Activity {
ImageButton imgButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imgButton = (ImageButton) findViewById(R.id.imgButton);
imgButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, 0);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == RESULT_CANCELED) return;
ParcelFileDescriptor fd;
try {
fd = getContentResolver().openFileDescriptor(data.getData(), "r");
} catch (FileNotFoundException e) {
e.printStackTrace();
return;
}
Bitmap bmp = BitmapFactory.decodeFileDescriptor(fd.getFileDescriptor());
imgButton.setImageBitmap(bmp);
}
}

Closed 5 years ago.
Source Code for get image from gallery and set it to image view and i want to pass the selected image in another activity and set it to linear layout.
private void galleryIntent() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
startActivityForResult(Intent.createChooser(intent, "Select File"), SELECT_FILE);
}
private void onSelectFromGalleryResult(Intent data) {
bitmap = null;
if (data != null) {
filePath = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());
System.out.println("bitmap is :" +bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
set.setImageBitmap(bitmap);
}
private static int RESULT_LOAD_IMAGE = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
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();
Intent i=new Intent(this,NextActivity.class);
i.putExtra("path",picturePath);
startActivity(i);
}
}
NextActivity File :-
String picturePath =getIntent().getStringExtra("path");
LinearLayout imageView = (LinearLayout) findViewById(R.id.imgView);
Bitmap bmImg = BitmapFactory.decodeFile(picturePath);
BitmapDrawable background = new BitmapDrawable(bmImg);
imageView.setBackgroundDrawable(background);

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 2 && resultCode == RESULT_OK
&& null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);

cursor.close();
bitmap = BitmapFactory.decodeFile(picturePath);
image.setImageBitmap(bitmap);
if (bitmap != null) {
ImageView rotate = (ImageView) findViewById(R.id.rotate);
}
}
pass selectedImage URI in Other Activity and using intent and use same code for generate the Bitmap with that URI
i searched and i found how to can to get image from gallery and show it in image view.this is a my source

i can to show image from gallery in image view,but i have two imageviews and when i click second imageview and choose some image result is first image view.i can't to show image only imageview witch i clicked.
how i can solve my problem? if anyone knows solution please help me
In onActivityResult you use the same variable credouploadcenter1left for both if...
Try:
if(choosebutton==1)
credouploadcenter1left.setImageBitmap(BitmapFactory.decodeFile(picturePath));
if(choosebutton==2)
credouploadcenter1.setImageBitmap(BitmapFactory .decodeFile(picturePath));
if(choosebutton==1)
credouploadcenter1left.setImageBitmap(BitmapFactory.decodeFile(picturePath));
if(choosebutton==2)
credouploadcenter1left.setImageBitmap(BitmapFactory.decodeFile(picturePath));
Here is the error, independently of your choose, you will set image always on credouploadcenter1left.
You have to set it on centeruploadcenter1 when you choose second button.
How Can I put image from directory instead of load from media. I load from gallery like this
String[] filePathColumn = { MediaStore.Images.Media.DATA };. How can load from /assets or /drawable-mdpi ? This is my code. Kindly tell me how can i used this code to add image from my directory?
public class ImageGalleryDemoActivity extends Activity {
private static int RESULT_LOAD_IMAGE = 1;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
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();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
You can put the respective drawables in the android drawables folders and Android would automatically choose the required drawable based upon the device display density. You can set the drawables as
imageView = (ImageView)findViewById(R.id.imageView);
imageView.setImageDrawable(getResources().getDrawable(R.drawable.image));
You can also take help from here.
this is the code i'm using currently,the code only displays the image from gallery. but i want to access the pixels of the image.i am confused exactly where the image data is stored in the code as in which variable.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
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();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
}
Please refer this Answer on SO, here is described to get Pixels, you should use:
Bitmap bm = BitmapFactory.decodeFile(picturePath);
and then :
bm.getPixel(x,y);// will return an int that corresponds to an int in the Color class, such as Color.BLACK or Color.WHITE.
Hope this may help you
I am new to android. I want to pick image from gallery. For 4.3 and below following code works fine. But not in 4.4. Please help.
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
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();
ImageView imageView = (ImageView) findViewById(R.id.imageView1);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
Looks like they have completely changed the way to pick a photo from the Gallery in Android 4.4, you have to use the Storage Access Framework as described here:
