效果图:
以上效果类似于显示点赞用户的界面,我们可以通过点击不同的昵称进入每个人的个人主页。
关于公共控件,请点击文章下方的git地址。
第一步:
我们为每个点赞的人建一个类用来代表个人的信息:
Person:
public class Person { public String name; public int age;}
很简单,就一个名字和年龄
第二步:
自定义TextView控件
创建PersonListView并继承BaseOnTextView这个抽象类:
public class PersonListView extends BaseOnTextView<Person> { public PersonListView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public PersonListView(Context context, AttributeSet attrs) { super(context, attrs); } public PersonListView(Context context) { super(context); } public void setVoteName(ArrayList<Person> list, int index) { this.getInfo(list); setVoteList(list, index); } /** * 设置点赞姓名 */ @Override public String getVoteName(Person data) { return data.name; } /** * 获取点赞人的信息 */ @Override public List<Person> getInfo(List<Person> list) { return list; }}
第三步:
将自定义的TextView放入xml中。
person_item.xml:
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <com.example.ontextview.PersonListView android:id="@+id/tv_vote_names" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@android:color/white" android:textScaleX="2" android:textSize="14sp" > </com.example.ontextview.PersonListView></LinearLayout>
第四步:
创建我们的Activity。
MainActivity:
public class MainActivity extends Activity { private ListView lv_lsit; private ArrayList<Person> personList=new ArrayList<Person>(); private PersonListAdapter mPersonListAdapter=new PersonListAdapter(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); } private void initView(){ String[] strs = {"火影忍者", "卡卡西", "漩涡鸣人", "宇智波鼬" ,"宇智波佐助","小樱","李洛克","大蛇丸","取个名字好难啊","请不要再来伤害我"}; for(int i=0;i<strs.length;i++){ Person obj=new Person(); obj.name=strs[i]; personList.add(obj); } lv_lsit=(ListView)findViewById(R.id.lv_lsit); lv_lsit.setAdapter(mPersonListAdapter); mPersonListAdapter.notifyDataSetChanged(); } class PersonListAdapter extends BaseAdapter{ @Override public int getCount() { return 1; } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder viewHolder; if(convertView==null){ viewHolder=new ViewHolder(); convertView=LayoutInflater.from(MainActivity.this).inflate(R.layout.person_item, null); viewHolder.tv_vote_names=(PersonListView)convertView.findViewById(R.id.tv_vote_names); convertView.setTag(viewHolder); }else{ viewHolder=(ViewHolder) convertView.getTag(); } viewHolder.tv_vote_names.setVoteList(personList, 0); return convertView; } } static class ViewHolder{ PersonListView tv_vote_names; } }
最后在TextViewSpan类中的onClick方法中添加事件。
public class TextViewSpan<T> extends ClickableSpan { private String clickString; private Context mContext; private int selectClick; private T votePerson; public TextViewSpan(String clickString, Context context, int selectClick) { this.clickString = clickString; this.mContext = context; this.selectClick = selectClick; } /** * 设置点赞人的信息 * * @param t */ public void setInfo(T t) { votePerson = t; } @Override public void updateDrawState(TextPaint ds) { ds.setColor(mContext.getResources().getColor(R.color.main_link)); ds.setUnderlineText(false); } @Override public void onClick(View widget) { switch (selectClick) { case 0:// 打开个人主界面 Person person = (Person) votePerson; Toast.makeText(mContext, person.name, Toast.LENGTH_SHORT).show(); break; case 1: break; default: break; } }}
