your project contains error(s),please fix them before running your application
如标题所示 eclipse中的 其中代码无显示任何错误 网上查阅良久 说什么重启或者删除项目重新导入 均试过 无效 就一个简单的spinner的练习 mars老师的 那么代码附上
package my.packge;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
public class SpinnerActivity extends Activity {
/** Called when the activity is first created. */
private Spinner spinner = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
spinner=(Spinner)findViewById(R.id.spinnerId);
ArrayAdapter<CharSequence> hsb=ArrayAdapter.createFromResource(this, R.array.planets_array, android.R.layout.simple_spinner_item);
hsb.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(hsb);
spinner.setPrompt("测试");
spinner.setOnItemSelectedListener(new SpinnerOnSelectedListener());
}
public class SpinnerOnSelectedListener implements OnItemSelectedListener{
public void onItemSelected(AdapterView<?> adapterView, View view, int position,
long id) {
String selected = adapterView.getItemAtPosition(position).toString();
System.out.println(selected);
}
public void onNothingSelected(AdapterView<?> adapterView) {
System.out.println("nothingSelected");
}}
}
