多选对话框

实现的方法为：

public void click3(View view){
AlertDialog.Builder builder=new AlertDialog.Builder(this);
builder.setTitle(“请选择您喜欢的水果：”);
final String []items={“苹果”,”梨”,”香蕉”,”鸡蛋”,”火龙果”};
final boolean[]checked={false,false,false,false,false};
builder.setMultiChoiceItems(items, checked, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {

            Toast.makeText(getApplicationContext(),items[which]+isChecked,Toast.LENGTH_SHORT).show();            checked[which]=isChecked;        }    });    builder.setPositiveButton("提交", new DialogInterface.OnClickListener() {        @Override        public void onClick(DialogInterface dialog, int which) {            StringBuffer sb=new StringBuffer();            for(int i=0;i<checked.length;i++){                if (checked[i]){                    sb.append(items[i]+" ");                }            }            Toast.makeText(getApplicationContext(),"您喜欢的水果为："+sb.toString(),Toast.LENGTH_SHORT).show();        }    });    builder.show();}
