Question

我的项目中有2个微调器，到目前为止只有一个微调器工作！我正在尝试使用2个微调器，当选择更改图像视图中的图像！第一个微调器从strings.xml中的数组中获取数据，并且还希望第二个数组执行相同操作并像第一个一样更新imageview！经过反复试验后，我无法弄清楚如何做到这一点并将编辑后的代码反馈给一个微调器！

public class SpinnerRes extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final String[] spstr = getResources().getStringArray(R.array.spinnervalue);
        final Spinner sp = (Spinner)findViewById(R.id.spinner1);

        final ArrayAdapter<String> ar = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item,spstr);
        sp.setAdapter(ar);

        sp.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                                       int arg2, long arg3) {
                final ImageView im = (ImageView)findViewById(R.id.imageView1);
                String s=((TextView)arg1).getText().toString();
                if(s.equals("A"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.a));
                if(s.equals("A6"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.a6));
                if(s.equals("A7"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.a7));
                if(s.equals("Am"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.am));

                if(s.equals("Am6"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.am6));
                if(s.equals("Am7"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.am7));
                if(s.equals("Amaj7"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.amaj7));
                if(s.equals("img8"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.img4));

                if(s.equals("img9"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.img1));
                if(s.equals("img10"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.img2));
                if(s.equals("img11"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.img3));
                if(s.equals("img12"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.img4));

                if(s.equals("img13"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.img1));
                if(s.equals("img14"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.img2));
                if(s.equals("img15"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.img3));
                if(s.equals("img16"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.img4));
            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub
            }
        });

    }
}

带有2个微调器的xml ..

<Spinner
    android:layout_height="40dp"
    android:layout_width="60dp"
    android:id="@+id/spinner1"
    android:layout_alignBottom="@+id/imageView"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_marginLeft="31dp"
    android:layout_marginStart="31dp">
</Spinner>
<Spinner
    android:layout_height="40dp"
    android:layout_width="50dp"
    android:id="@+id/spinner2"
    android:layout_alignTop="@+id/spinner1"
    android:layout_toRightOf="@+id/spinner1"
    android:layout_toEndOf="@+id/spinner1"
    android:layout_marginLeft="18dp"
    android:layout_marginStart="18dp">
</Spinner>

带有2个数组的strings.xml文件

<string-array name="spinnervalue">

Answer 1

使用这种方法：

public class SpinnerRes extends AppCompatActivity implements OnItemSelectedListener{

            @Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);

                final String[] spstr = getResources().getStringArray(R.array.spinnervalue);
                final Spinner sp = (Spinner)findViewById(R.id.spinner1);

                final ArrayAdapter<String> ar = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item,spstr);
                sp.setAdapter(ar);

               sp.setOnItemSelectedListener(this);

            }

        public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {

             Spinner spinner = (Spinner) parent;
             if(spinner.getId() == R.id.spinner1)
             {
               //do your staff                   
             }
             else if(spinner.getId() == R.id.spinner2)
             {
               //do your staff
             }

          }

    }

请查看此代码根据您做的更改，

    public class SpinnerRes extends Activity {
     ImageView im;
    Spinner sp,sp2;
     String[] spstr;
    String[] spstr2;
    ArrayAdapter<String> ar;
    ArrayAdapter<String> ar2;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.b);
        im = (ImageView)findViewById(R.id.imageView1);

        spstr = getResources().getStringArray(R.array.spinnervalue);
        spstr2 = getResources().getStringArray(R.array.spinnervalue2);
        sp = (Spinner)findViewById(R.id.spinner1);
        sp2 = (Spinner)findViewById(R.id.spinner2);

        ar = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item,spstr);
        ar2 = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item,spstr2);
        sp.setAdapter(ar);
        sp2.setAdapter(ar2);

        sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                                       int arg2, long arg3) {

                String text = sp.getSelectedItem().toString();
                if(text.equals("A"))
                    im.setImageDrawable(getResources().getDrawable(R.mipmap.ic_launcher));
                if(text.equals("A6"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.built_in_active));


            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub
            }
        });

        sp2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                                       int arg2, long arg3) {

                String text = sp2.getSelectedItem().toString();
                if(text.equals("A"))
                    im.setImageDrawable(getResources().getDrawable(R.mipmap.ic_launcher));
                if(text.equals("A6"))
                    im.setImageDrawable(getResources().getDrawable(R.drawable.built_in_active));


            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub
            }
        });

    }
}
