活动结果始终为0 [英] Activity result is always 0

问题描述

我寻找整天针对此问题：

  mUploadImage.setOnClickListener（新OnClickListener（）{        @覆盖
        公共无效的onClick（视图v）{
            意向意图=新意图（Intent.ACTION_GET_CONTENT）;
            intent.setType（图像/ *）;            startActivityForResult（
                    Intent.createChooser（意向，选择图片），
                    FILE_SELECT_ code）;
        }
    }）;
 

每当我点击mUploadImage的onActivityResult（）方法，将立即触发（虽然我不选择任何文件还）和结果code始终为0。谁能帮助我？

编辑：（从下面的评论）

 保护无效的onActivityResult（INT为arg0，ARG1 INT，意图ARG2）{
    如果（arg0都== FILE_SELECT_ code）{
        Log.v（TAG，选择图像结果code：+ ARG1）;
        如果（ARG1 == Activity.RESULT_OK）{
 

解决方案

检查这些问题的答案。所有这些说，有活动的launchMode之间的依赖立即报告结果

<一个href=\"http://stackoverflow.com/questions/3354955/onactivityresult-called-$p$pmaturely\">onActivityResult()所谓prematurely

<一个href=\"http://stackoverflow.com/questions/7910840/android-startactivityforresult-immediately-triggering-onactivityresult\">Android - startActivityForResult立即触发的onActivityResult

<一个href=\"http://stackoverflow.com/questions/8460250/onactivityresult-is-being-called-at-an-unexpected-time\">onActivityResult()是被称为在一个意想不到的时间

I search whole day for this issue:

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);
        }
    });

Whenever I click on mUploadImage OnActivityResult() method it will be triggered immediately (Although i dont choose any file yet) and result code always 0. can anyone help me?

EDIT: (from comment below)

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) {

解决方案

Check these answers. All of them say that there's a dependence between activity's launchMode and reporting result immediately

onActivityResult() called prematurely

Android - startActivityForResult immediately triggering onActivityResult

onActivityResult() is being called at an unexpected time
