我正在使用这样的意图:

Intent intent = new Intent(Intent.ACTION_PICK,
        android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);

在onActivityResult()我有这个:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode != Activity.RESULT_OK) {
        return; // user cancelled
    }

    Uri imageUri = data.getData();
    if (imageUri == null) {
        // (code to show error message goes here)
    return;
    }

    // Get image path from media store
    String[] filePathColumn = { android.provider.MediaStore.MediaColumns.DATA };
    Cursor cursor = this.getContentResolver().query(imageUri, filePathColumn,
            null, null, null);

    if (cursor == null || !cursor.moveToFirst()) { …

我正在使用以下代码在他/她的图库中使用用户自己的图像设置标记.但是我总是出现内存错误,所以我猜我的实现是错误的.我发现的另一个有趣的行为是,如果标记不在视图中,则不会立即发生错误.但是,一旦我将相机移动到该标记的位置,就会再次出现错误.(简而言之,我从未有机会看到我的形象)

我用的代码:

//on button click, send user to gallery to choose image he/she wants to use
changeAvatarButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            Intent i = new Intent(
                    Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(i, 1);
        }
    });


//use the selected image for marker icon
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 …
