Activity-1(The images are shown in gallery and the selected image is sent to new activity)
public class Gallery 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.gallery);
Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
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);
}
});
}
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 contentUri = data.getData();
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String tmppath = cursor.getString(column_index);
Bitmap croppedImage = BitmapFactory.decodeFile(tmppath);
// Bitmap croppedImage = BitmapFactory.decodeFile(croppedImage);
Intent intent = new Intent(Gallery.this,GesturesActivity.class);
intent.putExtra("bmp",croppedImage);
startActivity(intent);
Log.v("sending image","sending image");
}
}
}
