下面給個小demo

布局文件：

package com.alan.demoapp;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

	private TextView tv_main_name;
	private TextView tv_main_code;
	private EditText et_main_name;
	private EditText et_main_code;
	private Button btn_main_ma;
	private Button btn_main_da;
	private OnClickListener l = new OnClickListener() {
		@Override
		public void onClick(View v) {
			String name = et_main_name.getText().toString();
			String code = et_main_code.getText().toString();
			if (v == btn_main_ma) {
				Toast.makeText(MainActivity.this, "你罵了工號："+code+",姓名："+name, 0).show();
			} else {
				Toast.makeText(MainActivity.this, "你打了工號："+code+",姓名："+name, 0).show();
			}
		}
	};
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		//加載布局文件
		setContentView(R.layout.activity_main);
		tv_main_name = (TextView) findViewById(R.id.tv_main_name);
		tv_main_code = (TextView) findViewById(R.id.tv_main_code);
		et_main_name = (EditText) findViewById(R.id.et_main_name);
		et_main_code = (EditText) findViewById(R.id.et_main_code);
		btn_main_ma = (Button) findViewById(R.id.btn_main_ma);
		btn_main_da = (Button) findViewById(R.id.btn_main_da);
		btn_main_ma.setOnClickListener(l);
		btn_main_da.setOnClickListener(l);
	}
}
