我正在使用代码从图库中选择图片。
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gallery);
Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, SELECT_PICTURE);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == SELECT_PICTURE && 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]);
picturePath = cursor.getString(columnIndex);
cursor.close();
Log.v("picturePath", "picturePath: " + picturePath);
Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
Intent intentUpload = new Intent(GalleryActivity.this, UploadActivity.class);
// intentUpload.putExtra("BitmapImage", bitmap);
MyApplicationGlobal.bitmap = bitmap;
startActivity(intentUpload);
finish();
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
但是我遇到了错误
