我只是想设置一个文本视图，显示单击按钮时选中的复选框。
我希望有一天能够保留这些信息，但现在只知道选择了哪些信息就可以了。
我正在使用测试文本视图
有什么建议么？
public class skills_management extends Activity implements View.OnClickListener{
private Button buttonLocation;
private ListView mainListView ;
private Skill[] Skills ;
private ArrayAdapter<Skill> listAdapter ;
static CheckBox cb;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.skills);
Button buttonLocation = (Button) findViewById(R.id.buttonLocation);
buttonLocation.setOnClickListener(this);
// Find the ListView resource.
mainListView = (ListView) findViewById( R.id.mainListView );
// When item is tapped, toggle checked properties of CheckBox and Skill.
mainListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick( AdapterView<?> parent, View item, int position, long id) {
Skill Skill = listAdapter.getItem( position );
Skill.toggleChecked();
SkillViewHolder viewHolder = (SkillViewHolder) item.getTag();
viewHolder.getCheckBox().setChecked( Skill.isChecked() );
}
});
// Create and populate Management Skills.
Skills = (Skill[]) getLastNonConfigurationInstance() ;
if ( Skills == null ) {
Skills = new Skill[] {
new Skill("Fiscal Management"),
new Skill("Empowers Others"),
new Skill("Ethical"),
new Skill("Project Management"),
new Skill("Problem Solving"),
new Skill("Strategic"),
new Skill("Entrepreneurial"),
new Skill("Strong Communication"),
new Skill("Results Oriented"),
new Skill("Delegation"),
new Skill("Professional"),
new Skill("Decision Maker"),
new Skill("Sales"),
new Skill("Computer"),
new Skill("Marketing"),
new Skill("Training"),
new Skill("Executive")
};
}
ArrayList<Skill> SkillList = new ArrayList<Skill>();
SkillList.addAll( Arrays.asList(Skills) );
// Set our custom array adapter as the ListView's adapter.
listAdapter = new SkillArrayAdapter(this, SkillList);
mainListView.setAdapter( listAdapter );
}

}
@Override

// The child views in each row.

checkBox = (CheckBox) convertView.findViewById( R.id.CheckBox01 );
// Optimization: Tag the row with it's child views, so we don't have to
// call findViewById() later when we reuse the row.
convertView.setTag( new SkillViewHolder(textView,checkBox) );
// If CheckBox is toggled, update the Skill it is tagged with.
checkBox.setOnClickListener( new View.OnClickListener() {
public void onClick(View v) {

// Tag the CheckBox with the Skill it is displaying, so that we can
// access the Skill in onClick() when the CheckBox is toggled.
checkBox.setTag( Skill );
// Display Skill data
checkBox.setChecked( Skill.isChecked() );
textView.setText( Skill.getName() );
return convertView;
}//end class
}
}
