can anyone help me to solve this problem, how to call image from gallery/imagebutton to canvas for drawing? this is my snippet code :
buah1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(getBaseContext(), BelajarMewarnai.class);
startActivity(intent);
}
});
If anyone need a project I will send my project to email.
Actually i wanted to post the link in the comment for u but u seemed to bit less fimiliar with android(i thinking so), So i am posting my code to do that. First choose on which button click u want the user to be guided to gallery(only default gallery and not anything else, u may get a null pointer if u choose pic from any other).
On that button click u do this:
private void onClickOfButton(View v){
Intent galleryIntent=new Intent();
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
galleryIntent.setType("image/*");
startActivityForResult(Intent.createChooser(galleryIntent, "pic-select"), 10);//(10 its just a request code, u can give ur own, but same should there at receiving end )
}
Since u have started an activity for result, so u should be awaiting for a result from that started activity, so that activity will bring u the image and in ur activity u just collect it and put it into ur image view like this:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode==10 && resultCode==Activity.RESULT_OK){
try{
Uri selectImageUri=data.getData();
String selectedImagePath=getPath(selectImageUri);
Bitmap pic=BitmapFactory.decodeFile(selectedImagePath);
if(pic!=null){
yourImageView.setImageBitmap(pic);
}
}catch(NullPointerException ex){
Toast.makeText(getActivity().getBaseContext(), "Go to default gallery area and choose a pic", Toast.LENGTH_LONG).show();
}
}
else
super.onActivityResult(requestCode, resultCode, data);
}
The getPath method:
private String getPath(Uri uri) {
if( uri == null ) {
return null;
}
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getActivity().managedQuery(uri, projection, null, null, null);
if( cursor != null ){
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
return uri.getPath();
}
So this will do ur job...
try this:
buah1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(getBaseContext(), BelajarMewarnai.class);
Bundle bundle = new Bundle();
//Get the image name you clicked on
String imageName = getResources().getResourceName(imageId);;
//Send the image name as a string, which you want to load in the other activity
bundle.putString("image_to_load", imageName.split("/")[1].toString());
intent.putExtras(bundle);
startActivity(intent);
}
});
then you can get your image name in the next activity in onCreate like this:
//Here you can get the image name you already clicked in the previous activity to load in your canvas
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
String image_name = bundle.getString("image_to_load")
}
then you can set the image name to your imageView like this:
//Here you can get all resources in res folder
Resources res = getResources();
//define a new string which takes the image name you get from extras in the above code
String mDrawableName = image_name;
//Now you have the image name you clicked in theprevious activity, and ResID is to get the resource id from its name
int resID = res.getIdentifier(mDrawableName, "drawable", getPackageName());
//Here you can get the drawable from the resourceID you obtained in the above line
Drawable drawable = res.getDrawable(resID );
YOUR_IMAGE is the ImageView of the canvas you want to load the image inside in order to draw or whatever you want to do
drawView.setBackgroundDrawable(drawable);
I hope this will help..
