Android应用程式强制关闭，请协助我找出错误

Question

I'm currently coding an Android application, but I am quite new to Java so I don't know much. I have an activity (the one below) but when I launch it it force closes. Eclipse detects no errors, I don't either (but thats just normal lol). Please can you tell me what I got wrong and how to fix it. Thanks :) PS: The string called app_name is fine. It not that the error.

package com.rezoluz.fsx_pocket;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;

public class Shortcuts extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.shortcuts);

        Spinner selection = (Spinner) findViewById(R.id.shortcutsSpinner);
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
                this, R.array.shortcut_selection, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        selection.setAdapter(adapter);

        selection.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                TextView Text = (TextView)findViewById(R.id.shortcutsText);
                Text.setText(R.string.app_name);
            }
        });
    }
}

EDIT: Logcat gets this, I now understand the error, but don't know hom to fix it...

More specificly:

Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead

Answer 1

 selection.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                TextView Text = (TextView)findViewById(R.id.shortcutsText);
                Text.setText(R.string.app_name);
            }
        });

Replace the above OnClickListener code with the below one :

 selection.setOnItemSelectedListener(new OnItemSelectedListener() {


        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            TextView Text = (TextView)findViewById(R.id.shortcutsText); 
            Text.setText(R.string.app_name);

        }

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

        }


      });

Answer 2

I agree, Log cat would make this much easier. off the bat, it seems that you either have two different spinners

simple_spinner_dropdown_item

and

simple_spinner_item

or a typo ;)

Answer 3

Your error is clear:

Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead

So try setOnItemClickListener instead.

IE selection.setOnItemClickListener .

selection.setOnItemClickListener(new AdapterView.onItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
      // Code
   } 
});
