接口EditTextWithAddInterFace.java

使用接口是爲了讓使用的Activity實現添加按鈕的監聽

package com.chinaunicom.yczft.util;
/**
 * 
 * @author lxg
 * 2014-12-09 12:19:30
 */
public interface EditTextWithAddInterFace {
public void addButtonListener();
}

Activity 調用

public class YcInformationSendActivity extends Activity implements EditTextWithAddInterFace{
private EditTextWithAdd selectUserNames;//已選接收人
public void onCreate(Bundle savedInstanceState) {
selectUserNames=(EditTextWithAdd)findViewById(R.id.selectUserNames);
		selectUserNames.setActivity(this);
}
@Override
	public void addButtonListener() {添加點擊按鈕事件}
}
