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_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;

        	}

});
