仿QQ控件，朋友圈

仿QQ空间列表显示，只要原理是自定义一个控件继承ClickableSpan，在Adapter里面动态添加内容，注释在代码里已经写的很清楚了

遗留了一个问题，希望有人看到解决了也分享一下解决办法：

就是人名和整个TextView的点击冲突，点人名两个点击事件都响应。。。。

Activity：

public class MyActivity extends Activity {    /**     * Called when the activity is first created.     */    private ListView listView;    private MyAdapter mAdapter;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        listView = (ListView) findViewById(R.id.my_list);        mAdapter = new MyAdapter(this);        listView.setAdapter(mAdapter);        // TODO ListView里面有ClickableSpan的时候会影响listview的点击事件        // TODO 需要在adapter的布局上添加 android:descendantFocusability="blocksDescendants" 设置属性        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {                Toast.makeText(MyActivity.this,"呵呵呵",Toast.LENGTH_SHORT).show();            }        });        listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {            @Override            public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) {                Toast.makeText(MyActivity.this,"呵ddd",Toast.LENGTH_SHORT).show();                return true;            }        });    }}

Adapter:

public class MyAdapter extends BaseAdapter {    private Context mContext;    private String name1 = "叶良辰";    private String name2 = "赵日天";    public MyAdapter(Context mContext) {        this.mContext = mContext;    }    @Override    public int getCount() {        return 6;    }    @Override    public Object getItem(int i) {        return null;    }    @Override    public long getItemId(int i) {        return 0;    }    @Override    public View getView(int i, View view, ViewGroup viewGroup) {        ViewHolder holder;        if (view == null){            holder = new ViewHolder();            view = LayoutInflater.from(mContext).inflate(R.layout.list_item_layout,null);            holder.mLlPrsise = (LinearLayout) view.findViewById(R.id.ll_praise);            holder.mLlReply = (LinearLayout) view.findViewById(R.id.ll_reply);            view.setTag(holder);        }else{            holder = (ViewHolder) view.getTag();        }        // TODO 点赞得人        // TODO 这里可以用for循环动态添加，这就就添加了两个人        holder.mLlPrsise.removeAllViews();        ImageView praiseIcon = new ImageView(mContext);        praiseIcon.setPadding(0, 0, 8, 0);        praiseIcon.setImageDrawable(mContext.getResources().getDrawable(R.drawable.praise));        holder.mLlPrsise.addView(praiseIcon);        final TextView praise = new TextView(mContext);        praise.setMovementMethod(LinkMovementMethod.getInstance());        praise.setTextColor(mContext.getResources().getColor(                R.color.comment_name));        praise.setTextSize(14);        // 设置间距        praise.setPadding(2, 0, 2, 0);        SpannableString user = new SpannableString(name1 + "、");//回复人的名字        TextViewSpan clickableSpan1 = new TextViewSpan(name1 + "、", mContext, 0, 0);        clickableSpan1.setInfo(name1);        user.setSpan(clickableSpan1, 0, name1.length(),                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);        praise.setText(user);        holder.mLlPrsise.addView(praise);        final TextView praise2 = new TextView(mContext);        praise2.setMovementMethod(LinkMovementMethod.getInstance());        praise2.setTextColor(mContext.getResources().getColor(                R.color.comment_name));        praise2.setTextSize(14);        praise2.setPadding(2, 0, 2, 0);        SpannableString user2 = new SpannableString(name2);//回复人的名字        TextViewSpan clickableSpan2 = new TextViewSpan(name2, mContext, 0, 0);        clickableSpan2.setInfo(name2);        user2.setSpan(clickableSpan2, 0, name2.length(),                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);        praise2.setText(user2);        holder.mLlPrsise.addView(praise2);        TextView count = new TextView(mContext);        count.setTextColor(mContext.getResources().getColor(                R.color.comment_bg));        count.setTextSize(14);        count.setPadding(2, 0, 2, 0);        count.setText("2人觉得很赞");        holder.mLlPrsise.addView(count);        // TODO 评论内容        holder.mLlReply.removeAllViews();        TextView comment = new TextView(mContext);        comment.setMovementMethod(LinkMovementMethod.getInstance());        comment.setTextColor(mContext.getResources().getColor(                R.color.comment_bg));        comment.setTextSize(14);        SpannableString commentTo = new SpannableString(name1);        TextViewSpan clickName = new TextViewSpan(name1, mContext, 0,0);        commentTo.setSpan(clickName,0,commentTo.length(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE);        // TODO 处理人名的点击事件，需要什么参数传递过去一个对象（这里只传了了一个字符串）        clickName.setInfo(name1);        comment.setText(commentTo);        comment.append(":在下叶良辰");        holder.mLlReply.addView(comment);        TextView comment2 = new TextView(mContext);        comment2.setMovementMethod(LinkMovementMethod.getInstance());        comment2.setTextColor(mContext.getResources().getColor(                R.color.comment_bg));        comment2.setTextSize(14);        SpannableString commentTo2 = new SpannableString(name2);        TextViewSpan clickName2 = new TextViewSpan(name2, mContext, 0,0);        commentTo2.setSpan(clickName2,0,commentTo2.length(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE);        clickName2.setInfo(name2);        comment2.setText(commentTo2);        comment2.append("回复");        comment2.append(commentTo);        comment2.append(":我赵日天第一个表示不服。。。");        holder.mLlReply.addView(comment2);        // TODO 设置textview的点击颜色和点击事件        comment2.setBackgroundResource(R.drawable.comment_bg);        comment2.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                Toast.makeText(mContext,"回复谁谁谁",Toast.LENGTH_SHORT).show();            }        });        return view;    }    class ViewHolder{        LinearLayout mLlPrsise;        LinearLayout mLlReply;    }}

自定义控件：

public class TextViewSpan<T> extends ClickableSpan {private String clickString;private Context mContext;private int selectClick;private T votePerson;private int mColor;/** * * @param clickString 点击的内容 * @param context * @param selectClick  点击事件分类 * @param mColor  字体的颜色选择 */public TextViewSpan(String clickString, Context context, int selectClick, int mColor) {this.clickString = clickString;this.mContext=context;this.selectClick=selectClick;this.mColor = mColor;}/** * 设置点赞人的信息 * @param t */public void setInfo(T t){votePerson = t;}@Overridepublic void updateDrawState(TextPaint ds) {if (mColor == 1 ){ds.setColor(mContext.getResources().getColor(R.color.event_reg_color_1));} else if (mColor == 2){ds.setColor(mContext.getResources().getColor(R.color.event_reg_color_2));} else if (mColor == 3){ds.setColor(mContext.getResources().getColor(R.color.event_reg_color_3));}else{ds.setColor(mContext.getResources().getColor(R.color.comment_name));}ds.setUnderlineText(false); // 去掉下划线}@Overridepublic void onClick(View widget) {switch (selectClick) {case 0://Toast.makeText(mContext,votePerson.toString(),Toast.LENGTH_SHORT).show();break;case 1:/*Map<String,String> reply = (Map<String,String>)votePerson;Toast.makeText(mContext, reply.get(Constants.TALK_REPLY_NAME),Toast.LENGTH_SHORT).show();*/break;default:break;}}}
