在我的 android 应用程序中，我有“imageselect”模块从图库或相机捕获的图像中选择图像，以及“app”模块来处理和显示它。对于不同的请求代码我做了

public static final int REQUEST_CODE_PHOTO = 2000;
public static final int REQUEST_CODE_CAMERA = 2006;

在 imageselect 模块活动中完美地获取请求代码和结果代码

两个选项的开始活动结果

//to choose gallery image 
Intent intent = new Intent(getApplicationContext(), ImageSelectActivity.class);
intent.putExtra(Constants.INTENT_EXTRA_ALBUM, albums.get(position).name);
startActivityForResult(intent, Constants.REQUEST_CODE_PHOTO); 


// to capture camera image     
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, Constants.REQUEST_CODE_CAMERA);

OnActivity 结果：

if(requestCode == Constants.REQUEST_CODE_PHOTO && resultCode == RESULT_OK && data != null) {
        setResult(RESULT_OK, data);
        finish();
        Toast.makeText(AlbumSelectActivity.this,"Calling ALbum IF",Toast.LENGTH_SHORT).show();
    }else if(requestCode == Constants.REQUEST_CODE_CAMERA && resultCode == RESULT_OK && data != null){
        setResult(RESULT_OK, data);
        finish();
        Toast.makeText(AlbumSelectActivity.this,"Calling ALbum ELSE IF",Toast.LENGTH_SHORT).show();
    }

直到它工作正常。在我的应用程序模块活动中总是得到相同的请求代码。总是得到 2000，这是照片请求代码。

应用模块 MainActivity onActivityResult:

if (resultCode == RESULT_OK) {
        if (requestCode == Constants.REQUEST_CODE_PHOTO && data != null) {
           // always getting 'REQUEST_CODE_PHOTO' so this block is working 

        } else if (requestCode == Constants.REQUEST_CODE_CAMERA && data != null) {
            // this block never called even when 'REQUEST_CODE_CAMERA' passed 
        }
    }

试试这个App 模块 MainActivity onActivityResult：

if (resultCode == RESULT_OK) {
        if (requestCode == Constants.REQUEST_CODE_PHOTO && data != null) {
           // always getting 'REQUEST_CODE_PHOTO' so this block is working 

        } else if(requestCode == Constants.REQUEST_CODE_CAMERA && data != null) {
            // this block never called even when 'REQUEST_CODE_CAMERA' passed 
        }else{}
    }

对于OnActivity 结果：

if(requestCode == Constants.REQUEST_CODE_PHOTO && resultCode == RESULT_OK && data != null) {
        setResult(RESULT_OK, data);
        finish();
        Toast.makeText(AlbumSelectActivity.this,"Calling ALbum IF",Toast.LENGTH_SHORT).show();
    }else if(requestCode == Constants.REQUEST_CODE_CAMERA && resultCode == RESULT_OK && data != null){
        setResult(RESULT_OK, data);
        finish();
        Toast.makeText(AlbumSelectActivity.this,"Calling ALbum ELSE IF",Toast.LENGTH_SHORT).show();
    }else{}
