android - variable string = value(string) 但结果为假

Question

请帮忙，

为什么结果 if(Title.toString().trim() == "camera") 是 false？
我的代码:

mGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
                //Get item at position
                GridMenuItem item = (GridMenuItem) parent.getItemAtPosition(position);
                String Title =item.getTitle();
                if(Title.toString().trim() == "camera"){

                    String strPhoneNumber;
                    Bundle b = getIntent().getExtras();
                    strPhoneNumber = b.getString("phonenumber");

                    Intent myIntent = new Intent(v.getContext(), UploadActivity.class);
                    Bundle bs = new Bundle();
                    bs.putString("phonenumber", strPhoneNumber); //Your id
                    myIntent.putExtras(b); //Put your id to your next Intent
                    startActivityForResult(myIntent, 0);
                    finish();
                }
                if(Title.toString() =="history"){
                    Intent myIntent = new Intent(v.getContext(), HistoryActivity.class);
                    startActivityForResult(myIntent, 0);
                }
                if(Title.toString() =="setting"){
                    Intent myIntent = new Intent(v.getContext(), HistoryActivity.class);
                    startActivityForResult(myIntent, 0);
                }

            }
        });

像这样更改代码:

mGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
                //Get item at position
                GridMenuItem item = (GridMenuItem) parent.getItemAtPosition(position);
                String Title =item.getTitle().toString().trim();
                Log.d("testString",Title);
                if(Title.equals("camera")){

                    String strPhoneNumber;
                    Bundle b = getIntent().getExtras();
                    strPhoneNumber = b.getString("phonenumber");

                    Intent myIntent = new Intent(v.getContext(), UploadActivity.class);
                    Bundle bs = new Bundle();
                    bs.putString("phonenumber", strPhoneNumber); //Your id
                    myIntent.putExtras(b); //Put your id to your next Intent
                    startActivityForResult(myIntent, 0);
                    finish();
                }
                if(Title.equals("history")){
                    Intent myIntent = new Intent(v.getContext(), HistoryActivity.class);
                    startActivityForResult(myIntent, 0);
                }
                if(Title.equals("setting")){
                    Intent myIntent = new Intent(v.getContext(), HistoryActivity.class);
                    startActivityForResult(myIntent, 0);
                }

            }
        });

请在下面的评论中发布日志“testString”的值。查看它是否显示“Camera”而不是“camera”，然后相应地更改 if 语句。
