【问题描述】：

我想通过 Android 应用将两张不同的照片添加到数据库中。但是，当我为第一张照片选择一张照片时，它会为两张照片放置同一张照片并以相同的方式保存。我的代码在下面。我为两张不同的照片定义了两个单独的图像视图，但它不起作用。我能做什么？

 mDenemeImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(Intent.ACTION_PICK);
                intent.setType("image/*");
                startActivityForResult(intent, 1);
            }
        });


        mDenemeImage2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(Intent.ACTION_PICK);
                i.setType("image/*");
                startActivityForResult(i, 1);
            }
        });
     private void getUserInfo(){
        mDriverDatabase.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                if(dataSnapshot.exists() && dataSnapshot.getChildrenCount()>0){
                    Map<String, Object> map = (Map<String, Object>) dataSnapshot.getValue();

                    if(map.get("profileDenemeUrl")!=null){
                        mprofileDenemeUrl = map.get("profileDenemeUrl").toString();
                        Glide.with(getApplication()).load(mprofileDenemeUrl).into(mDenemeImage);
                    }
                     if(map.get("profileDenemeUrl2")!=null){
                        mprofileDenemeUrl2 = map.get("profileDenemeUrl2").toString();
                        Glide.with(getApplication()).load(mprofileDenemeUrl2).into(mDenemeImage2);
                    }


                }
            }

            @Override

            }
        });
    }

【问题讨论】：

您能否粘贴完整的代码，包括您将意图传递给画廊以选择两个不同图像的位置。

mDenemeImage.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) {
        Intent intent = new Intent(Intent.ACTION_PICK); 
        intent.setType("image/*"); 
        startActivityForResult(intent, 1); 
    }
}); 

mDenemeImage2.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) {
        Intent i = new Intent(Intent.ACTION_PICK); 
        intent.setType("image/*"); startActivityForResult(i, 2); 
    }
}); 

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

    if(requestCode == 1 && resultCode == RESULT_OK){
        Uri imageUri1 = data.getData();
        resultUri1 = imageUri1;

        mDenemeImage.setImageURI(resultUri1);
    }

    if (requestCode == 2 && resultCode == RESULT_OK)
    {
        Uri imageUri2 = data.getData();
        resultUri2 = imageUri2;

        mDenemeImage2.setImageURI(resultUri2);
    }
}
