先上效果图:
首先来写一个表情的GridView
public class EmotionView extends LinearLayout implements OnItemClickListener { private GridView mGridView; private static final ArrayList<Integer> emotionDisplayList = new ArrayList<Integer>(); public static final LinkedHashMap<Integer, String> emotionsKeySrc = new LinkedHashMap<Integer, String>(); public static final HashMap<String, Integer> emotionsKeyString = new HashMap<String, Integer>(); private class GridViewAdapter extends BaseAdapter { List<Integer> list; public GridViewAdapter(List<Integer> list) { super(); this.list = list; } public int getCount() { return list.size(); } public Object getItem(int position) { return list.get(position); } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { int resId = (Integer) getItem(position); ImageView iv = null; if (convertView == null) { iv = (ImageView) (convertView = new ImageView(getContext() .getApplicationContext())); } else { iv = (ImageView) convertView; } iv.setImageResource(resId); iv.setBackgroundResource(R.drawable.bg_face); int height = getResources().getDimensionPixelSize( R.dimen.emotion_item_view_height); iv.setPadding(0, height, 0, height); return iv; } } static { emotionsKeySrc.put(R.drawable.face1, "怒"); emotionsKeySrc.put(R.drawable.face2, "蛋糕"); emotionsKeySrc.put(R.drawable.face3, "蜡烛"); emotionsKeySrc.put(R.drawable.face4, "干杯"); emotionsKeySrc.put(R.drawable.face5, "抓狂"); emotionsKeySrc.put(R.drawable.face6, "衰"); emotionsKeySrc.put(R.drawable.face7, "晕"); emotionsKeySrc.put(R.drawable.face8, "粽子"); emotionsKeySrc.put(R.drawable.face9, "风扇"); emotionsKeySrc.put(R.drawable.face10, "花"); emotionsKeySrc.put(R.drawable.face11, "足球"); emotionsKeySrc.put(R.drawable.face12, "绿丝带"); emotionsKeySrc.put(R.drawable.face13, "哼"); emotionsKeySrc.put(R.drawable.face14, "心"); emotionsKeySrc.put(R.drawable.face15, "冰棍"); emotionsKeySrc.put(R.drawable.face16, "哈哈"); emotionsKeySrc.put(R.drawable.face17, "爱你"); emotionsKeySrc.put(R.drawable.face18, "月亮"); emotionsKeySrc.put(R.drawable.face19, "猪头"); emotionsKeySrc.put(R.drawable.face20, "下雨"); emotionsKeySrc.put(R.drawable.face21, "红牌"); emotionsKeySrc.put(R.drawable.face22, "泪"); emotionsKeySrc.put(R.drawable.face23, "哨子"); emotionsKeySrc.put(R.drawable.face24, "困"); emotionsKeySrc.put(R.drawable.face25, "呵呵"); emotionsKeySrc.put(R.drawable.face26, "阳光"); emotionsKeySrc.put(R.drawable.face27, "汗"); emotionsKeySrc.put(R.drawable.face28, "黄牌"); emotionsKeySrc.put(R.drawable.face29, "嘻嘻"); emotionsKeySrc.put(R.drawable.face30, "伤心"); Iterator<Integer> iterator = emotionsKeySrc.keySet().iterator(); int i = 0; while (iterator.hasNext()) { int temp = iterator.next(); emotionsKeyString.put(emotionsKeySrc.get(temp), temp); emotionDisplayList.add(temp); i++; } } public interface EmotionAdapter { void doAction(int resId, String desc); } public EmotionView(Context context) { super(context); initViews(); } public EmotionView(Context context, AttributeSet attrs) { super(context, attrs); initViews(); } private void initViews() { Context context = getContext(); LayoutInflater.from(context).inflate(R.layout.emotion_main, this); mGridView = (GridView) findViewById(R.id.gridView); mGridView.setAdapter(new GridViewAdapter(emotionDisplayList)); mGridView.setOnItemClickListener(this); } @Override public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) { int value = emotionDisplayList.get(position); listener.onclick(value); } MyListener listener; public void setListener(MyListener listener) { this.listener = listener; }}Layout是:
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="@dimen/emotion_view_height" android:background="#d1d8e3" > <GridView android:id="@+id/gridView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:numColumns="@integer/emotion_colnum" android:cacheColorHint="@null" android:stretchMode="columnWidth" android:listSelector="#00000000" android:fadingEdgeLength="0dp" > </GridView></RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" > <com.example.weibotest.view.EmotionView android:id="@+id/emotion_view" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerInParent="true" /> <EditText android:id="@+id/textview" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:textSize="18sp" android:textColor="#000000" android:layout_marginBottom="10dp" android:layout_above="@id/emotion_view" /></RelativeLayout>
Activity里这样来写:
EmotionView mEmotionView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final TextView textView = (TextView)findViewById(R.id.textview); mEmotionView = (EmotionView) findViewById(R.id.emotion_view); textView.setText("<strong>a[晕]dfsfdf[阳光]ds</strong>"); String str1 = textView.getText().toString(); SpannableString spannableString = new SpannableString(str1); Pattern pattern = null;<strong> pattern = Pattern.compile("\\[(\\S+?)\\]"); //这里是过滤出[XX]这种形式的字符串，下面是把这种形式的字符串替换成对应的表情</strong> Matcher matcher = pattern.matcher(str1); Integer drawableSrc = null; while (matcher.find()) { int start = matcher.start(); int end = matcher.end(); drawableSrc = EmotionView.emotionsKeyString.get<strong>(matcher.group(1))</strong>; if (drawableSrc != null && drawableSrc > 0) { <strong>spannableString.setSpan(new ImageSpan(MainActivity.this, drawableSrc), start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);</strong> } } textView.setText(spannableString,TextView.BufferType.SPANNABLE); mEmotionView.setListener(new MyListener() { @Override public void onclick(int value) { String str1 = textView.getText().toString(); SpannableString str = new SpannableString(str1); if (value > 0) { str.setSpan(new ImageSpan(MainActivity.this, value), 4, 5, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); textView.setText(str,TextView.BufferType.SPANNABLE); } } });代码:http://download.csdn.net/detail/baidu_nod/7697419
