onActivityResult-resultCode始终为0

Question

我在onActivityResult上遇到问题，无论我在做什么，我都无法正确得到resultCode。

我知道也有类似的问题，但最后他们没有帮助我，我也无法解决

MainActivity：将打开新的Activity Popup.class的方法

public void openShopView(){
    Intent intent = new Intent(this, Popup.class);
    Bundle b = new Bundle();

    b.putString("which", "ShopMain");
    intent.putExtras(b);
    startActivityForResult(intent, 1);
}

第二个活动：方法将打开另一个具有不同布局的Activity Popup.class

shop_c1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent(getIntent());
            Bundle b = new Bundle();

            b.putString("which", "ShopBuildings");
            intent.putExtras(b);
            startActivity(intent);
            finish();
        }
    });

第三活动：并且有应该设置结果并关闭活动的方法

building2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Log.i("LOG_NEW: ", "" + getCurrentBuildingTable(1) + ", " + checkSlotTable(1));
            if(getCurrentBuildingTable(1) && checkSlotTable(1) == -1) {
                Intent returnIntent = getIntent();
                returnIntent.putExtra("result", 1);
                setResult(RESULT_OK, returnIntent);
                finish();
            }else if (checkSlotTable(1) == -1){
                Log.i("LOG_NEW: ", "Building already exist");
            }
            else{
                Log.i("LOG_NEW: ", "Not enough resources");
            }
        }
    });

最后是MainActivity的onActivityResult（）

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    Log.i("LOG_RES: ", "Checking.. " + requestCode + ", " + resultCode);
    if (requestCode == 1) {
        if(resultCode == RESULT_OK){
            String result = data.getStringExtra("result");
            Log.i("LOG_RES: ", result);

        }
    }
}

无论我在做什么，我都无法启动if（resultCode == RESULT_OK）循环，并且resultCode始终为0。

感谢帮助

由于在startActivityForResult中传递了第二个活动的意图，因此必须在Second Activity中调用setResult 。

但是，您可以将Third Activity的结果代码委托给Second Activity，然后委托给Third。

将您的第二个活动更改为以下内容：

shop_c1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(getIntent());
                Bundle b = new Bundle();

                b.putString("which", "ShopBuildings");
                intent.putExtras(b);
                startActivityForResult(intent,1);
                //Remove finish from here
            }
        });

然后在“ 第二活动”中添加

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode==1){
    setResult(resultCode,data);
    }

    finish();
}
