活动结果始终为0

Question

我整天搜索这个问题：

mUploadImage.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
            intent.setType("image/*");

            startActivityForResult(
                    Intent.createChooser(intent, "Select a Picture"),
                    FILE_SELECT_CODE);
        }
    });

每当我点击mUploadImage OnActivityResult（）方法时，它会立即被触发（虽然我还没有选择任何文件）并且结果代码始终为0.任何人都可以帮助我吗？

编辑:(来自下面的评论）

protected void onActivityResult(int arg0, int arg1, Intent arg2) {
    if (arg0 == FILE_SELECT_CODE) {
        Log.v(TAG, "Selected a image. Result code: " + arg1);
        if (arg1 == Activity.RESULT_OK) {

检查这些答案。所有人都说活动的launchMode和报告结果之间存在依赖关系

onActivityResult() called prematurely

Android - startActivityForResult immediately triggering onActivityResult

onActivityResult() is being called at an unexpected time
