android - 微调 onitemclicklistener 不工作

Question

我的应用程序中有一个微调器，但在单击某个项目时它不起作用。我得到了值，但 if 条件不起作用。

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
                Object item = parent.getItemAtPosition(pos);

                String Text = effecttwo.getSelectedItem().toString();
                System.out.println("spinner is -"+item+"-");

// I get the correct values in System.out.println

                if(Text=="Hue"){

           // not entering into this condition or any other condition       

                }else if(Text=="Saturation"){


                }else if(Text=="Brightness"){



                }else{

                }


            }
            public void onNothingSelected(AdapterView<?> parent) {
            }
        });

请告诉我我做错了什么。

Answer 1

I get the values but the if condition is not getting worked.

if(Text=="Hue"){

错

使用.equals 或.equalsIgnoreCase 比较字符串

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#equals(java.lang.Object)

if(Text.equals("Hue"))
{

}

What is the difference between == vs equals() in Java?
