最近在做个聊天软件 实现了弹出表情选择表情插入EditText
现在想实现用快捷键显示表情 像QQ一样输入/wx 就出现一个微笑表情
实现了写/wx出现微笑表情 接着写/wx就不行了 我郁闷了 帅哥.美女们帮帮忙
代码如下
public class MainActivity extends Activity { private static String TAG="MainActivity"; private Button expressionButton; private LayoutInflater inflater; private GridView mGridView; private EditText et; private Dialog dialog; //预定义的系统表情 private int[]face=new int[] { R.drawable.smiley_b_close,R.drawable.smiley_colon_apostrophe_open, R.drawable.smiley_colon_close,R.drawable.smiley_colon_d, R.drawable.smiley_colon_dollar,R.drawable.smiley_colon_e, R.drawable.smiley_colon_o,R.drawable.smiley_colon_open, R.drawable.smiley_colon_p,R.drawable.smiley_colon_pipe, R.drawable.smiley_colon_s,R.drawable.smiley_colon_slash, R.drawable.smiley_colon_star,R.drawable.smiley_colon_three, R.drawable.smiley_colon_x,R.drawable.smiley_greater_than_colon_open, R.drawable.smiley_kik,R.drawable.smiley_less_than_slash_three, R.drawable.smiley_less_than_three,R.drawable.smiley_semicolon_close }; private ImageGetter imageGetter = new ImageGetter() { @Override public Drawable getDrawable(String source) { int id = Integer.parseInt(source); Drawable draw = getResources().getDrawable(id); draw.setBounds(0, 0, draw.getIntrinsicWidth(), draw.getIntrinsicHeight()); return draw; } }; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); et=(EditText) findViewById(R.id.EditText1); expressionButton = (Button) findViewById(R.id.expressionButton); inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.customdialog, null); //获取自定义对话框中的GridView mGridView = (GridView) layout.findViewById(R.id.gridview); mGridView.setAdapter(new ImageAdapter(MainActivity.this)); //使用快捷键快速出现表情 et.setOnKeyListener(new EditText.OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { EditText ev = (EditText) v; String s_ev = ev.getText().toString().trim(); //Log.i(TAG, s_ev); //Log.i(TAG, ExpressShortCut.AX_POSITION+""); if(s_ev.equals(ExpressShortCut.SYSTEM_EXPRESS_MJ)) { et.setText(""); et.append(Html.fromHtml("<img src='"+face[ExpressShortCut.MJ_POSITION]+"'/>",imageGetter,null)); }return false; }});
