Android中的多个旋转器

Question

我想在一个页面上创建2个微调器。我的代码在onItemSelected;

下面

@Override

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

    switch(arg0.getId()) {
    case R.id.spinner1:

        switch(arg2){

        case 0:
        Toast.makeText(this,  "THIS IS SPINNER 1" ,  Toast.LENGTH_SHORT).show();
        break;
        case 1:
        Intent intent1 = new Intent(this, Screen2.class);
        startActivity(intent1);
        break;
        case 2:
        Intent intent2 = new Intent(this, Screen2.class);
        startActivity(intent2);
        break;}

    case R.id.spinner2:

        switch(arg2){
        case 0:
        Toast.makeText(this,  "THIS IS SPINNER 2" ,  Toast.LENGTH_SHORT).show();
        break;
        case 1:
        Intent intent1 = new Intent(this, Screen3.class);
        startActivity(intent1);
        break;
        case 2:
        Intent intent2 = new Intent(this, Screen3.class);
        startActivity(intent2);
        break;
        }
    }
    }

但是当我运行该程序时，案例没有像我预期的那样响应，例如，当它应该转到screen2时，spinner 2将它发送到screen3

Answer 1

我自己找到了答案，如下：

int a = arg0.getId();

    if (a==R.id.spinner1){
        switch(arg2) {

//Do something
                                 }

    if (a==R.id.spinner2){
        switch(arg2) {

//Do something
                                 }
