onActivityResult - resultCode始终为0

Question

我有onActivityResult的问题，无论我在做什么我无法得到resultCode的权利。

我知道有类似的问题，但最后他们并没有帮助我，我不能修复它

MainActivity：方法，该方法将打开新的活动Popup.class

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

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

次活动：方法，该方法将打开另一个活动Popup.class只是不同的布局

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：和有方法，其应的setResult和靠近活性

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"); 
      } 
     } 
    }); 

在末端有onActivityResult（）从MainActivity

@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I” m我无法启动if（resultCode == RESULT_OK） loop和resultCode始终为0 ..

感谢您的帮助

Answer 1

setResult必须次活动被调用，因为第二个活动的意图在startActivityForResult获得通过。

但是，您可以将第三活动的结果代码委托给第二活动，然后委托给第三活动。

您次活动更改为这样的事情：

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 
      } 
     }); 

然后也次活动添加此

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

    finish(); 
}
