调用自定义活动为startActivityForResult [英] call custom Activity as startActivityForResult

问题描述

我开始一个活动的结果，为

I am starting an Activity for result as

startActivityForResult(new Intent(this,ActivityA.class),REQUEST_CODE)

ActivityA启动。有在ActivityA一个gridview，我想获得所选图像的方法onActivityResult主叫活动的位置（INT申请code，INT结果code，意图数据），但我没有得到这样做的方式

ActivityA is started. There is a gridview on ActivityA, I want to get the position of selected image in method onActivityResult(int requestCode, int resultCode, Intent data) of caller Activity but I am not getting the way to do that

推荐答案

在活动A，

onItemClick（） GridView控件的

//create a new intent...
Intent intent = new Intent();
intent.putInt("position",position);
setResult(RESULT_OK,intent);
//close this Activity...
finish();

在来电的活动，

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent){
        super.onActivityResult(requestCode, resultCode, intent);
        Bundle extras = intent.getExtras();
        if(extras != null)
        int position = extras.getInt("position");
    }
