问题:

setOnItemClickListener Not Works with Spinner. Here is my code...

supplier.setOnItemClickListener(new OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position,
                        long id) {
                    // TODO Auto-generated method stub

                    String msupplier=supplier.getSelectedItem().toString();
                    Log.e("Selected item : ",msupplier);

                }
            });

回答1:

setOnItemClickListener will not works with spinner. Try using this method:

setOnItemSelectedListener

Change your code like following:

supplier.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                // TODO Auto-generated method stub
                String msupplier=supplier.getSelectedItem().toString();

                Log.e("Selected item : ",msupplier);
}

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

            }
        });

1. I think you should check your xml file which contains the spinner. Make sure haven't set android:clickable = "false".

2. please check your spinner adapter and make sure in your getView(int position, View convertView, ViewGroup parent) method, you haven't set any widget click callback event such as Button,Imageview,TextView

回答3:

OnItemSelectedListener() serves a different purpose than a click listener. Most importantly, it doesn't fire if you click on the currently selected item again. In some cases this might not be a problem but in other cases, it might well be. So the real answer is not to tell people to use a different and probably unsuitable listener but to solve the original problem. :-)

Fortunately, we can place the click listener on the adapter instead:

public class SpinnerClickAdapter extends BaseAdapter implements SpinnerAdapter {
  protected OnItemClickListener listener;

  public SpinnerClickAdapter(Context context, ..., OnItemClickListener listener) {
    super();

    this.listener = listener;
  }

  @Override
  public View getDropDownView(final int position, View convertView, final ViewGroup parent) {
    if (convertView == null)
      convertView = LayoutInflater.from(context).inflate(R.layout.yourlayout, false);

    convertView.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        if (listener != null)
          listener.onItemClick((AdapterView<?>) parent, v, position, getItemId(position));
      }
    });


    // ...

    return convertView;
  }
}

and then we can use it as usual, with the only difference of not setting it on the spinner but on the adapter instead:

Spinner spinner = (Spinner) findViewById(R.id.yourspinner);
SpinnerClickAdapter spinnerAdapter = new SpinnerClickAdapter(context, ..., new AdapterView.OnItemClickListener() {
  @Override
  public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    // TODO
  }
});
spinner.setAdapter(spinnerAdapter);

I may be going off course, but thought to suggest you to use OnItemSelectedListener which is broader than OnItemClickListener for Spinners:

supplier.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
        long arg3) {
        //do something here
    }
    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        //optionally do something here
    }
});

回答5:

Use getItemAtPosition:

supplier.getItemAtPosition(position).toString();

回答6:

Use this

supplier.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub

        }

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

        }
    });

回答7:

I think supplier in your code means spinner, do Replace this line

 String msupplier=supplier.getSelectedItem().toString();

with the below line:

 String msupplier= supplier.getItemAtPosition(position).toString();

i have faced this issues. setOnItemClickListener will not works with spinner. My solution is as following:

mSpinnerYears.setAdapter(adapter);
    mSpinnerYears.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            Logger.d(new StringBuilder(2).append("TAG:").append(TAG).toString(),
                    new StringBuilder(3).append("click pos = ").append(position).append(
                            mSpinnerYears.getItemAtPosition(position).toString()).toString());
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });
